I am trying to fill a form in a php application from a C# client (Outlook addin). I used Fiddler to see the original request from within the php application and the form is transmitted as a multipart/form. Unfortunately .Net does not come with native support for this type of forms (WebClient has only a method for uploading a file).
Does anybody know a library or has some code to achieve this? I want to post different values and additionally (but only sometimes) a file.

Thanks for your help,
Sebastian

Multipart forms from C# client

&gt; *Wrong question asked, see my update below*

I need to integrate my AngularJS Project with an existing RESTful API. These API consume POST request which `upload a file`, and also submit the form data in a request. Unfortunately, one of the form input requires to be in `Content-Type: Application/json`.

After search on the web, I could only `POST` with `Content-Type: multipart/form-data` in which each of the parts does not have a specific `MIME`. 
How can I compose my `multipart/form-data` with a different `MIME`  for each parts in Javascript?

    POST /api/v1/inventory
    Host: localhost:8000
    Origin: http://localhost:9000
    Content-Type: multipart/form-data; boundary=------border

    ------border
    Content-Disposition: form-data; name=&quot;owner&quot;
    
    john doe
    ------border
    Content-Disposition: form-data; name=&quot;image&quot;; filename=&quot;mybook.png&quot;
    Content-Type: image/png


    ------border
    Content-Disposition: form-data; name=&quot;items&quot;
    Content-Type: application/json

    {&quot;name&quot;: &quot;Book&quot;, &quot;quantity&quot;: &quot;12&quot;}
    ------border--

# Update

Apologize for asking a wrong question. The original problem is that, I can see the server calling the logic something like, 

    func POST(req):
         owner = req.owner // This is string
         image = req.image // This is file object
         itemQuantity = req.items.quantity // Items is an object with attribute quantity
         itemName = req.items.name // Items is an object with attribute name
         
I have also managed to figure out how to submit such a post request. I will post my answer below. 

Once again sorry for asking a wrong question.


Composing multipart/form-data with a different Content-Type on each parts with Javascript (or Angular)

Problem: When POSTing data with Python&#39;s urllib2, all data is URL encoded and sent as Content-Type: application/x-www-form-urlencoded.  When uploading files, the Content-Type should instead be set to multipart/form-data and the contents be MIME-encoded.

To get around this limitation some sharp coders created a library called MultipartPostHandler which creates an OpenerDirector you can use with urllib2 to mostly automatically POST with multipart/form-data. A copy of this library is here: [MultipartPostHandler doesn&#39;t work for Unicode files ][1]

I am new to Python and am unable to get this library to work. I wrote out essentially the following code. When I capture it in a local HTTP proxy, I can see that the data is still URL encoded and not multi-part MIME-encoded. Please help me figure out what I am doing wrong or a better way to get this done. Thanks :-)

    FROM_ADDR = &#39;my@email.com&#39;
    
    try:
    	data = open(file, &#39;rb&#39;).read()
    except:
    	print &quot;Error: could not open file %s for reading&quot; % file
    	print &quot;Check permissions on the file or folder it resides in&quot;
    	sys.exit(1)
    
    # Build the POST request
    url = &quot;http://somedomain.com/?action=analyze&quot;		
    post_data = {}
    post_data[&#39;analysisType&#39;] = &#39;file&#39;
    post_data[&#39;executable&#39;] = data
    post_data[&#39;notification&#39;] = &#39;email&#39;
    post_data[&#39;email&#39;] = FROM_ADDR
    
    # MIME encode the POST payload
    opener = urllib2.build_opener(MultipartPostHandler.MultipartPostHandler)
    urllib2.install_opener(opener)
    request = urllib2.Request(url, post_data)
    request.set_proxy(&#39;127.0.0.1:8080&#39;, &#39;http&#39;) # For testing with Burp Proxy
    
    # Make the request and capture the response
    try:
    	response = urllib2.urlopen(request)
    	print response.geturl()
    except urllib2.URLError, e:
    	print &quot;File upload failed...&quot;

EDIT1: Thanks for your response. I&#39;m aware of the ActiveState httplib solution to this (I linked to it above). I&#39;d rather abstract away the problem and use a minimal amount of code to continue using urllib2 how I have been. Any idea why the opener isn&#39;t being installed and used?

Using MultipartPostHandler to POST form-data with Python

i am having a problem with uploading image with multipart-form

here is my code i used from this [answer](https://stackoverflow.com/questions/26162616/upload-image-with-parameters-in-swift)

        var request = NSMutableURLRequest(URL: url!)
        request.HTTPMethod = &quot;POST&quot;
        
        var boundary = generateBoundaryString()
        request.setValue(&quot;multipart/form-data; boundary=\(boundary)&quot;, forHTTPHeaderField: &quot;Content-Type&quot;)
        
        var body = NSMutableData()
        
        if self.img.image != nil {
            var imageData = UIImagePNGRepresentation(self.img.image)
            
            if imageData != nil {
                body.appendString(&quot;--\(boundary)\r\n&quot;)
                body.appendString(&quot;Content-Disposition: form-data; name=\&quot;image\&quot;; filename=\&quot;image.png\&quot;\r\n&quot;)
                body.appendString(&quot;Content-Type: image/png\r\n\r\n&quot;)
                body.appendData(imageData!)
                body.appendString(&quot;\r\n&quot;)
            }
            
        }
        
        body.appendString(&quot;--\(boundary)--\r\n&quot;)
        request.setValue(&quot;\(body.length)&quot;, forHTTPHeaderField:&quot;Content-Length&quot;)
        request.HTTPBody = body

then i use NSURLSession to apply the request

the server says that i didn&#39;t choose image to upload i only want to upload the image for now 

do i have to use paths of images to upload any image or it&#39;s data is enough?

do i miss any thing , any help to understand this ?

Upload image with multipart form-data iOS in Swift

I&#39;m using FormData to upload files. I also want to send an array of other data. 

When I send just the image, it works fine. When I append some text to the formdata, it works fine. When I try to attach the &#39;tags&#39; array below, everything else works fine but no array is sent.

Any known issues with FormData and appending arrays?

Instantiate formData:

`formdata = new FormData();`
   
The array I create. Console.log shows everything working fine.

            // Get the tags
    		tags = new Array();
    		$(&#39;.tag-form&#39;).each(function(i){
    			article = $(this).find(&#39;input[name=&quot;article&quot;]&#39;).val();
    			gender = $(this).find(&#39;input[name=&quot;gender&quot;]&#39;).val();
    			brand = $(this).find(&#39;input[name=&quot;brand&quot;]&#39;).val();
    			this_tag = new Array();
    			this_tag.article = article;
    			this_tag.gender = gender;
    			this_tag.brand = brand;
    			tags.push(this_tag);	
    			console.log(&#39;This is tags array: &#39;);
    			console.log(tags);
    		});
    		formdata.append(&#39;tags&#39;, tags);
    		console.log(&#39;This is formdata: &#39;);
    		console.log(formdata);
    
How I send it: 

    		// Send to server
    		$.ajax({
    			url: &quot;../../build/ajaxes/upload-photo.php&quot;,
    			type: &quot;POST&quot;,
    			data: formdata,
    			processData: false,
    			contentType: false,
    			success: function (response) {
    				console.log(response);
    				$.fancybox.close();
    			}
    		});

Can I append an array to &#39;formdata&#39; in javascript?

How can I can convert my JS Object to `FormData`?

The reason why I want to do this is, I have an object that I constructed out of the ~100 form field values. 

    var item = {
       description: &#39;Some Item&#39;,
       price : &#39;0.00&#39;,
       srate : &#39;0.00&#39;,
       color : &#39;red&#39;,
       ...
       ...
    }

Now I am asked to add the upload file functionality to my form which, of-course is impossible via JSON and so I am planning on moving to `FormData`. So is there any way that I can convert my JS object to `FormData`?

Convert JS Object to form data

Does anyone know how to use the `HttpClient` in .Net 4.5 with `multipart/form-data` upload? 

I couldn&#39;t find any examples on the internet.

C# HttpClient 4.5 multipart/form-data upload

I am currently using the Chrome Addon Postman - REST Client to easily create POST / GET request.

Now I want to debug an upload script and I am **looking for a way to make requests encoded as &quot;multipart/form-data&quot;** so that I can send also a file.



How to send multipart/form-data request using Postman

I am wondering if anyone can share with me an example of multipart/form-data that contains:

 1. Some form parameters
 2. Multiple files

Example of multipart/form-data

I&#39;ve got a problem sending a file to a serverside PHP-script using jQuery&#39;s ajax-function.
It&#39;s possible to get the File-List with `$(&#39;#fileinput&#39;).attr(&#39;files&#39;)` but how is it possible to send this Data to the server? The resulting array (`$_POST`) on the serverside php-script is 0 (`NULL`) when using the file-input.

I know it is possible (though I didn&#39;t find any jQuery solutions until now, only Prototye code ([http://webreflection.blogspot.com/2009/03/safari-4-multiple-upload-with-progress.html][1])).

This seems to be relatively new, so please do not mention file upload would be impossible via XHR/Ajax, because it&#39;s definitely working.

I need the functionality in Safari 5, FF and Chrome would be nice but are not essential.

My code for now is:

    $.ajax({
        url: &#39;php/upload.php&#39;,
        data: $(&#39;#file&#39;).attr(&#39;files&#39;),
        cache: false,
        contentType: &#39;multipart/form-data&#39;,
        processData: false,
        type: &#39;POST&#39;,
        success: function(data){
            alert(data);
        }
    });

Sending multipart/formdata with jQuery.ajax

I am developing Windows Phone 8 app. I want to upload SQLite database via PHP web service using HTTP POST request with MIME type multipart/form-data &amp; a string data called &quot;userid=SOME_ID&quot;. 

I don&#39;t want to use 3rd party libs like HttpClient, RestSharp or MyToolkit. I tried the below code but it doesn&#39;t upload the file &amp; also doesn&#39;t give me any errors. It&#39;s working fine in Android, PHP, etc so there&#39;s no issue in web service. Below is my given code (for WP8). what&#39;s wrong with it?

I&#39;ve googled and I&#39;m not getting specific for WP8

&lt;!-- language: lang-csharp --&gt;

        //IsolatedStorageFile instead of StorageFile
        //var file = await ApplicationData.Current.LocalFolder.GetFileAsync(DBNAME);
        byte[] fileBytes = null;
        using (var stream = await file.OpenReadAsync())
        {
            fileBytes = new byte[stream.Size];
            using (var reader = new DataReader(stream))
            {

How to upload file to server with HTTP POST multipart/form-data?

The [XMLHttpRequest Level 2](http://www.w3.org/TR/XMLHttpRequest2/) standard (still a working draft) defines the `FormData` interface. This interface enables appending `File` objects to XHR-requests (Ajax-requests).

Btw, this is a new feature - in the past, the &quot;hidden-iframe-trick&quot; was used (read about that in [my other question](https://stackoverflow.com/questions/6718664/is-it-possible-to-peform-an-asynchronous-cross-domain-file-upload/6963843)).

This is how it works (example):

    var xhr = new XMLHttpRequest(),
        fd = new FormData();
    
    fd.append( &#39;file&#39;, input.files[0] );
    xhr.open( &#39;POST&#39;, &#39;http://example.com/script.php&#39;, true );
    xhr.onreadystatechange = handler;
    xhr.send( fd );

where `input` is a `&lt;input type=&quot;file&quot;&gt;` field, and `handler` is the success-handler for the Ajax-request.

This works beautifully in all browsers (again, except IE).

Now, I would like to make this functionality work with jQuery. I tried this:


    var fd = new FormData();    
    fd.append( &#39;file&#39;, input.files[0] );

    $.post( &#39;http://example.com/script.php&#39;, fd, handler );

Unfortunately, that won&#39;t work (an &quot;Illegal invocation&quot; error is thrown - [screenshot is here](http://i.imgur.com/Uy8Xu.png)). I assume jQuery expects a simple key-value object representing form-field-names / values, and the `FormData` instance that I&#39;m passing in is apparently incompatible.

Now, since it is possible to pass a `FormData` instance into `xhr.send()`, I hope that it is also possible to make it work with jQuery.

**Update:**

I&#39;ve created a &quot;feature ticket&quot; over at jQuery&#39;s Bug Tracker. It&#39;s here: http://bugs.jquery.com/ticket/9995

I was suggested to use an &quot;Ajax prefilter&quot;...

---

**Update:**

First, let me give a demo demonstrating what behavior I would like to achieve. 

HTML:

    &lt;form&gt;
        &lt;input type=&quot;file&quot; id=&quot;file&quot; name=&quot;file&quot;&gt;
        &lt;input type=&quot;submit&quot;&gt;
    &lt;/form&gt;

JavaScript:

    $( &#39;form&#39; ).submit(function ( e ) {
        var data, xhr;
        
        data = new FormData();
        data.append( &#39;file&#39;, $( &#39;#file&#39; )[0].files[0] );
        
        xhr = new XMLHttpRequest();
        
        xhr.open( &#39;POST&#39;, &#39;http://hacheck.tel.fer.hr/xml.pl&#39;, true );
        xhr.onreadystatechange = function ( response ) {};
        xhr.send( data );
        
        e.preventDefault();
    });

The above code results in this HTTP-request:

![multipartformdata][1]

**This is what I need** - I want that &quot;multipart/form-data&quot; content-type!

---

The proposed solution would be like so:

    $( &#39;form&#39; ).submit(function ( e ) {
        var data;
        
        data = new FormData();
        data.append( &#39;file&#39;, $( &#39;#file&#39; )[0].files[0] );
       
        $.ajax({
            url: &#39;http://hacheck.tel.fer.hr/xml.pl&#39;,
            data: data,
            processData: false,
            type: &#39;POST&#39;,
            success: function ( data ) {
                alert( data );
            }
        });
        
        e.preventDefault();
    });

However, this results in:

![wrongcontenttype][2]

As you can see, the content type is wrong...

How to send FormData objects with Ajax-requests in jQuery?

When I curl something, it works fine:

    curl -L -i -H &#39;x-device-id: abc&#39; -F &quot;url=http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4&quot;  http://example.com/upload

How do I get this to work right with axios? I&#39;m using react if that matters:

    uploadURL (url) {
      return axios.post({
        url: &#39;http://example.com/upload&#39;,
        data: {
          url: url
        },
        headers: {
          &#39;x-device-id&#39;: &#39;stuff&#39;,
          &#39;Content-Type&#39;: &#39;multipart/form-data&#39;
        }
      })
      .then((response) =&gt; response.data)
    }

This doesn&#39;t work for some reason.

How do I set multipart in axios with react?

I have problem uploading file using POST request in Node.js. I have to use `request` module to accomplish that (no external npms). Server needs it to be multipart request with the `file` field containing file&#39;s data. What seems to be easy it&#39;s pretty hard to do in Node.js without using any external module.

I&#39;ve tried using [this example][1] but without success:

    request.post({
      uri: url,
      method: &#39;POST&#39;,
      multipart: [{
        body: &#39;&lt;FILE_DATA&gt;&#39;
      }]
    }, function (err, resp, body) {
      if (err) {
        console.log(&#39;Error!&#39;);
      } else {
        console.log(&#39;URL: &#39; + body);
      }
    });

I&#39;m pretty green to HttpClient and I&#39;m finding the lack of (and or blatantly incorrect) documentation extremely frustrating.  I&#39;m trying to implement the following post (listed below) with Apache Http Client, but have no idea how to actually do it.

Apache HttpClient making multipart form post

I&#39;m trying to do something I thought would be relatively simple: Upload an image to a server with the Android SDK. I&#39;m found a lot of example code:

[http://groups.google.com/group/android-developers/browse_thread/thread/f9e17bbaf50c5fc/46145fcacd450e48][1]

[http://linklens.blogspot.com/2009/06/android-multipart-upload.html][2]


But neither work for me. The confusion I keep running into is what is really needed to make a multipart request. What is the _simplest_ way to have a multipart upload (with an image) for Android?

Any help or advice would be greatly appreciated!

Post multipart request with Android SDK

What does `enctype=&#39;multipart/form-data&#39;` mean in an HTML form and when should we use it?

What does enctype=&#39;multipart/form-data&#39; mean?

I ran into a problem while trying to upload a file to my S3 bucket. Everything works except that my file paramters do not seem appropriate. I am using Amazon S3 sdk to upload from nodejs to s3.

These are my routes settings:

	var multiparty = require(&#39;connect-multiparty&#39;),
	    multipartyMiddleware = multiparty();
    app.route(&#39;/api/items/upload&#39;).post(multipartyMiddleware, items.upload);

This is items.upload() function:

    exports.upload = function(req, res) {
    	var file = req.files.file;
    	var s3bucket = new AWS.S3({params: {Bucket: &#39;mybucketname&#39;}});
    	s3bucket.createBucket(function() {
    		var params = {
    			Key: file.name,
    			Body: file
    		};
    		s3bucket.upload(params, function(err, data) {
    			console.log(&quot;PRINT FILE:&quot;, file);
        		if (err) {
          			console.log(&#39;ERROR MSG: &#39;, err);
       			} else {
         			console.log(&#39;Successfully uploaded data&#39;);
      			}
      		});
    	});
    };

Setting `Body` param to a string like `&quot;hello&quot;` works fine. According to [doc][1], `Body` param must take  *(Buffer, Typed Array, Blob, String, ReadableStream) Object data.* However, uploading a file object fails with the following error message:

    [Error: Unsupported body payload object]

This is the file object:

    { fieldName: &#39;file&#39;,
      originalFilename: &#39;second_fnp.png&#39;,

I want to create an employee information in the system by uploading an image along with employee data. I am able to do it with different rest calls using jersey. But I want to achieve in one rest call.
I provide below the structure. Please help me how to do in this regard.


    @POST
	@Path(&quot;/upload2&quot;)
	@Consumes({MediaType.MULTIPART_FORM_DATA,MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
	public Response uploadFileWithData(
			@FormDataParam(&quot;file&quot;) InputStream fileInputStream,
			@FormDataParam(&quot;file&quot;) FormDataContentDisposition contentDispositionHeader,
            Employee emp) {

    //..... business login
    
    }



Whenever I am trying to do, I get error in Chrome postman. The simple structure of my Employee json is given below.

    {
        &quot;Name&quot;: &quot;John&quot;,
        &quot;Age&quot;: 23,
        &quot;Email&quot;: &quot;john@gmail.com&quot;,
        &quot;Adrs&quot;: {
            &quot;DoorNo&quot;: &quot;12-A&quot;,
            &quot;Street&quot;: &quot;Street-11&quot;,
            &quot;City&quot;: &quot;Bangalore&quot;,
            &quot;Country&quot;: &quot;Karnataka&quot;
        }
    }

However I can do it by making two different call, but I want to achieve in one rest call so that I can receive the file as well as the actual data of the employee.

Request you to help in this regard.


File upload along with other object in Jersey restful web service

I am trying to figure this out. I was not getting any useful error messages with my code so I used something else to generate something. I have attached that code after the error message.  I have found a [tutorial][1] on it but I do not know how to implement it with what I have. This is what I currently have:

How to set up a Web API controller for multipart/form-data

I am trying to develop a sidebar gadget that automates the process of checking a web page for the evolution of my transfer quota. I am almost at it but there is one last step I need to get it working: Sending an HttpRequest with the correct POST data to a php page. Using a firefox plugin, here is what the &quot;Content-Type&quot; of the header looks like:

    Content-Type=multipart/form-data; boundary=---------------------------99614912995

with the parameter &quot;boundary&quot; seeming to be random, and the POSTDATA is this:

    POSTDATA =-----------------------------99614912995
    Content-Disposition: form-data; name=&quot;SOMENAME&quot;

    Formulaire de Quota
    -----------------------------99614912995
    Content-Disposition: form-data; name=&quot;OTHERNAME&quot;

    SOMEDATA
    -----------------------------99614912995--


I do not understand how to correctly emulate the POSTDATA with the mystery &quot;boundary&quot; parameter coming back.

Would someone know how I can solve this? 

What is the boundary parameter in an HTTP multi-part (POST) Request?

So this HTML code submits the data in the correct format for me.

	&lt;form action=&quot;https://www.example.com/register.php&quot; method=&quot;post&quot; enctype=&quot;multipart/form-data&quot;&gt;
		Name: &lt;input type=&quot;text&quot; name=&quot;userName&quot;&gt;&lt;BR /&gt;
		Email: &lt;input type=&quot;text&quot; name=&quot;userEmail&quot;&gt;&lt;BR /&gt;
		Password: &lt;input type=&quot;text&quot; name=&quot;userPassword&quot;&gt;&lt;BR /&gt;
		Avatar: &lt;input type=&quot;file&quot; name=&quot;avatar&quot;&gt;&lt;BR /&gt;
		&lt;input type=&quot;submit&quot;&gt;
	&lt;/form&gt;

I&#39;ve looked into a good number of articles on how to do a multipart/form-data POST on iOS, but none really explain what to do if there were normal parameters as well as the file upload.

Could you please help me with the code to POST this in Obj-C?

Thanks!

Over the internet I found there are plenty of example which shows How to upload MULTIPART file using RESTFul API. But with same solution. I am not able to run those code as well.
I think I am doing something wrong with the JAR files. Could anyone please help me on this?
