If you want to submit a POST request

 1. You have to set the “**request header**” section of the Firefox plugin to have a “**name**” = “**`Content-Type`**” and “**value**” = “**`application/x-www-form-urlencoded`**”
 2. Now, you are able to submit parameter like “`name=mynamehere&amp;title=TA`” in the “request body” text area field

Here is a step by step guide (I think this should come pre-loaded with the add-on):

1. In the top menu of RESTClient -&gt; Headers -&gt; Custom Header
2. In the pop-up box, enter **Name**: `Content-Type` and **Value**: `application/x-www-form-urlencoded` 
3. Check the &quot;Save to favorite&quot; box and click Okay.  
 Now you will see a &quot;Headers&quot; section with your newly added data.
5. Then in the Body section, you can enter your data to post like:

        username=test&amp;name=Firstname+Lastname

6. Whenever you want to make a post request, from the Headers main menu, select the `Content-Type:application/x-www-form-urlencoded` item that you added and it should work.

You can send the parameters in the URL of the POST request itself. 

Example URL: 

    localhost:8080/abc/getDetails?paramter1=value1&amp;parameter2=value2

Once you copy such type of URL in Firefox REST client make a POST call to the server you want

Request header needs to be set as per below image.[![add request header][1]][1]


request body can be passed as json string in text area.

I tried the methods mentioned in some other answers, but they look like workarounds to me. Using Firefox Add-on RESTclient to send HTTP POST requests with parameters is not straightforward in my opinion, at least for the version I&#39;m currently using, 2.0.1.

Instead, try using other free open source tools, such as Apache JMeter. It is simple and straightforward (see the screenshot as below)

I have a pip requirements file that changes during development.

Can `pip` be made to **uninstall** packages that do not appear in the requirements file as well as installing those that do appear? Is there a standard method?

This would allow the pip requirements file to be the canonical list of packages - an &#39;if and only if&#39; approach.

**Update**: I suggested it as a new feature at https://github.com/pypa/pip/issues/716

How can I use a pip requirements file to uninstall as well as install packages?

Firefox Add-on RESTclient - How to input POST parameters?

<p>I've installed Firefox RESTclient add-on but , I'm having hard time figuring out how to pass POST parameters. Is there a specific format to do this? Or is there any other tool which can be used to debug an REST API on Mac OS X ?</p>


I would like to use $resource to call my RESTful web service, (which I am still working on) but I would like to find out if I got my AngularJS script correct first.

The todo DTO has: `{id, order, content, done}`

`:cmd` is so I can call `api/1/todo/reset` to clear the todo table in database.

Here is the code with comment of my understanding:

    function TodoService($resource) {
        var src = $resource(&#39;api/1/todo/:id:cmd&#39;,
                  {id: &quot;@id&quot;, cmd: &quot;@cmd&quot;}, //parameters default
                  {
                    ListTodos: { method: &quot;GET&quot;, params: {} },
                    GetTodo: { method: &quot;GET&quot;, params: { id: 0 } },                            
                    CreateTodo: { method: &quot;POST&quot;, params: { content: &quot;&quot;, order: 0, done: false } },
                    UpdateTodo: { method: &quot;PATCH&quot;, params: { /*...*/ } },
                    DeleteTodo: { method: &quot;DELETE&quot;, params: { id: 0 } },
                    ResetTodos: { method: &quot;GET&quot;, params: { cmd: &quot;reset&quot; } },
                  });
    
        //Usage:

        //GET without ID
        //it calls -&gt; api/1/todo
        src.ListTodos();
        
        //GET with ID
        //it calls -&gt; api/1/todo/4
        src.GetTodo({ id: 4 });
    
        //POST with content, order, done
        //it calls -&gt; api/1/todo
        src.CreateTodo({ content: &quot;learn Javascript&quot;, order: 1, done: false });
    
        //UPDATE content only
        //it calls -&gt; api/1/todo/5
        src.UpdateTodo({ id: 5, content: &quot;learn AngularJS&quot; }); 
   
        //UPDATE done only
        //it calls -&gt; api/1/todo/5
        src.UpdateTodo({ id: 5, done: true });
        
        //RESET with cmd
        //it calls -&gt; api/1/todo/reset
        src.ResetTodos();
    }

One particular thing I am not sure is the PATCH method, I don&#39;t want to update everything, can I update just one field? Am I constructing this piece of code correctly?

AngularJS $resource RESTful example

Let&#39;s say you want to get list of users by calling `GET` to `api/users`, but currently the table was truncated so there are no users. What is the proper response for this scenario: `404` or `204`?

Proper REST response for empty table?

I am planning to develop a web based chat application which takes in ReSTful requests, translate them to XMPP and deliver them to an XMPP server.

Using websockets for this kind of chat based application looked promising as the events (or responses) can be delivered asynchronously. But if I use websockets as the underlying protocol for transferring the requests from the browser, can this still be considered as a ReSTful design? If yes, how are the URIs, verbs (GET, POST...), parameters represented in the websocket message? Wrap them in an xml/json and send it?

Also, ReSTful architecture states that no session state will be stored on the server. But here in this case when an XMPP client session is created, the state of this session will be stored on the server (violating the stateless constraint)

Is ReST over websockets possible?

I&#39;m using the ASP.NET WebApi to create a RESTful API.  I&#39;m creating a PUT method within one of my controllers, and the code looks like this:

	public HttpResponseMessage Put(int idAssessment, int idCaseStudy, string value) {
		var response = Request.CreateResponse();
		if (!response.Headers.Contains(&quot;Content-Type&quot;)) {
			response.Headers.Add(&quot;Content-Type&quot;, &quot;text/plain&quot;);
		}

		response.StatusCode = HttpStatusCode.OK;
		return response;
	}

When I PUT to that location with the browser via AJAX, it gives me this Exception:

&gt; Misused header name. Make sure request headers are used with
&gt; HttpRequestMessage, response headers with HttpResponseMessage, and
&gt; content headers with HttpContent objects.

But isn&#39;t `Content-Type` a perfectly valid header for a response?  Why am I getting this exception?

Can&#39;t set Content-Type header on HttpResponseMessage headers?

When designing resource hierarchies, when should one use sub-resources?

I used to believe that when a resource could not exist without another, it should be represented as its sub-resource. I recently ran across this counter-example:

* An employee is uniquely identifiable across all companies.
* An employee&#39;s access control and life-cycle depend on the company.

I modeled this as: `/companies/{companyName}/employee/{employeeId}`

Notice, I don&#39;t need to look up the company in order to locate the employee, so should I? If I do, I&#39;m paying a price to look up information I don&#39;t need. If I don&#39;t, this URL mistakenly returns HTTP 200:

`/companies/{nonExistingName}/employee/{existingId}`

1. How should I represent the fact that a resource to *belongs* to another?
2. How should I represent the fact that a resource *cannot be identified* without another?
3. What relationships are sub-resources meant and not meant to model?

RESTful design: when to use sub-resources?

I&#39;ve written the following piece of code in my nodeJS/Expressjs server:

```
app.post(&#39;/settings&#39;, function(req, res){
	var myData = {
		a: req.param(&#39;a&#39;)
		,b: req.param(&#39;b&#39;)
		,c: req.param(&#39;c&#39;)
		,d: req.param(&#39;d&#39;)
	}

	var outputFilename = &#39;config.json&#39;;

	fs.writeFile(outputFilename, JSON.stringify(myData, null, 4), function(err) {
		if(err) {
		  console.log(err);
		} else {
		  console.log(&quot;Config file as been overwriten&quot;);
		}
	}); 
});
```

This allows me to get the submitted form data and write it to a JSON file.

This works perfectly. But the client remains in some kind of posting state and eventually times out. So I need to send some kind of success state or success header back to the client. 

How should I do this?

Thank you in advance!

How can I send a success status to browser from nodejs/express?

I have a link that I need to submit a post request with. Normally, I&#39;d use jQuery and prevent the link&#39;s default behavior and then submit a form to the destination. This seems like something Rails should be able to help me out with. Sure enough, the `link_to` method has an option for specifying a POST http method:

    link_to &quot;Profile&quot;, &#39;http://example.com/profile&#39;, method: :post

That works, but I need to add 2 parameters too. I tried:

    link_to &quot;Profile&quot;, &#39;http://example.com/profile&#39;, method: post, param1: &#39;value1&#39;, param2: &#39;value2&#39;

That just added those parameters to the `&lt;a&gt;` HTML element, but didn&#39;t submit those when clicking the link:

    &lt;a rel=&quot;nofollow&quot; param1=&quot;value1&quot; param2=&quot;value2&quot; data-method=&quot;post&quot; href=&quot;http://example.com/profile&quot;&gt;Profile&lt;/a&gt;

Is there a way to do a POST request with parameters using `link_to` or any other Rails method? I&#39;m using Rails 3.2.9.

Using Rails link_to for links that post

I am using Flask and MongoDB. I am trying to convert the content of request.form into something suitable for saving via PyMongo. It seems like something that should come up often enough to have a ready-made solution.

So what Flask give me is something like:

    ImmutableMultiDict([(&#39;default&#39;, u&#39;&#39;), (&#39;required&#39;: u&#39;on&#39;), (&#39;name&#39;, u&#39;short_text&#39;), (&#39;name&#39;, u&#39;another&#39;), (&#39;submit&#39;, u&#39;Submit&#39;)])

And what I am looking to get is something close to this:

    {
      &#39;default&#39;: &#39;&#39;,
      &#39;name&#39;: [&#39;short_text&#39;, &#39;another&#39;],
      &#39;required&#39;: true
    }


In Flask convert form POST object into a representation suitable for mongodb

After reading many similar sounding problems and the relevant Flask docs, I cannot seem to figure out what is generating the following error upon submitting a form:

&gt; 400 Bad Request
&gt;
&gt; The browser (or proxy) sent a request that this server could not understand.

While the form always displays properly, the bad request happens when I submit an HTML form that ties to either of these functions: 

    @app.route(&#39;/app/business&#39;, methods=[&#39;GET&#39;, &#39;POST&#39;])
    def apply_business():
        if request.method == &#39;POST&#39;:    
            new_account = Business(name=request.form[&#39;name_field&#39;], email=request.form[&#39;email_field&#39;], account_type=&quot;business&quot;, 
                q1=request.form[&#39;q1_field&#39;], q2=request.form[&#39;q2_field&#39;], q3=request.form[&#39;q3_field&#39;], q4=request.form[&#39;q4_field&#39;], 
                q5=request.form[&#39;q5_field&#39;], q6=request.form[&#39;q6_field&#39;], q7=request.form[&#39;q7_field&#39;],
                account_status=&quot;pending&quot;, time=datetime.datetime.utcnow())
            db.session.add(new_account)
            db.session.commit()
            session[&#39;name&#39;] = request.form[&#39;name_field&#39;]    
            return redirect(url_for(&#39;success&#39;))
        return render_template(&#39;application.html&#39;, accounttype=&quot;business&quot;)          
    
    @app.route(&#39;/app/student&#39;, methods=[&#39;GET&#39;, &#39;POST&#39;])
    def apply_student():    
        if request.method == &#39;POST&#39;:    
            new_account = Student(name=request.form[&#39;name_field&#39;], email=request.form[&#39;email_field&#39;], account_type=&quot;student&quot;, 
                q1=request.form[&#39;q1_field&#39;], q2=request.form[&#39;q2_field&#39;], q3=request.form[&#39;q3_field&#39;], q4=request.form[&#39;q4_field&#39;], 
                q5=request.form[&#39;q5_field&#39;], q6=request.form[&#39;q6_field&#39;], q7=request.form[&#39;q7_field&#39;], q8=request.form[&#39;q8_field&#39;], 
                q9=request.form[&#39;q9_field&#39;], q10=request.form[&#39;q10_field&#39;],
                account_status=&quot;pending&quot;, time=datetime.datetime.utcnow())
            db.session.add(new_account)
            db.session.commit()
            session[&#39;name&#39;] = request.form[&#39;name_field&#39;]    
            return redirect(url_for(&#39;success&#39;)) 
        return render_template(&#39;application.html&#39;, accounttype=&quot;student&quot;)

The relevant part of HTML is

&lt;!-- language: lang-html --&gt;

    &lt;html&gt;
    &lt;head&gt;
        &lt;title&gt;apply&lt;/title&gt;
    &lt;/head&gt;
    &lt;body&gt;
        {% if accounttype==&quot;business&quot; %}
        &lt;form action=&quot;{{ url_for(&#39;apply_business&#39;) }}&quot; method=post class=&quot;application_form&quot;&gt;
        {% elif accounttype==&quot;student&quot; %}
        &lt;form action=&quot;{{ url_for(&#39;apply_student&#39;) }}&quot; method=post class=&quot;application_form&quot;&gt;     
        {% endif %} 
        &lt;p&gt;Full Name:&lt;/p&gt;
        &lt;input name=&quot;name_field&quot; placeholder=&quot;First and Last&quot;&gt;
        &lt;p&gt;Email Address:&lt;/p&gt;
        &lt;input name=&quot;email_field&quot; placeholder=&quot;your@email.com&quot;&gt;
        ...

The problem for most people was not calling ``GET`` or ``POST``, but I am doing just that in both functions, and I double checked to make sure I imported everything necessary, such as ``from flask import request``. I also queried the database and confirmed that the additions from the form weren&#39;t added.

In the Flask app, I was requesting form fields that were labeled slightly different in the HTML form. Keeping the names consistent is a must. More can be read at this question https://stackoverflow.com/questions/8552675/form-sending-error-flask

What is the cause of the Bad Request Error when submitting form in Flask application?

I am writing some code to interface with redmine and I need to upload some files as part of the process, but I am not sure how to do a POST request from python containing a binary file.

I am trying to mimic the commands [here][1]:

    curl --data-binary &quot;@image.png&quot; -H &quot;Content-Type: application/octet-stream&quot; -X POST -u login:password http://redmine/uploads.xml

In python (below), but it does not seem to work. I am not sure if the problem is somehow related to encoding the file or if something is wrong with the headers.

    import urllib2, os

    FilePath = &quot;C:\somefolder\somefile.7z&quot;
    FileData = open(FilePath, &quot;rb&quot;)
    length = os.path.getsize(FilePath)

    password_manager = urllib2.HTTPPasswordMgrWithDefaultRealm()
    password_manager.add_password(None, &#39;http://redmine/&#39;, &#39;admin&#39;, &#39;admin&#39;)
    auth_handler = urllib2.HTTPBasicAuthHandler(password_manager)
    opener = urllib2.build_opener(auth_handler)
    urllib2.install_opener(opener)
    request = urllib2.Request( r&#39;http://redmine/uploads.xml&#39;, FileData)
    request.add_header(&#39;Content-Length&#39;, &#39;%d&#39; % length)
    request.add_header(&#39;Content-Type&#39;, &#39;application/octet-stream&#39;)
    try:
        response = urllib2.urlopen( request)
        print response.read()
    except urllib2.HTTPError as e:
        error_message = e.read()
        print error_message

I&#39;m planning to develop a simple Firefox extension that will shorten URL of a currently active tab, display a popup with the shortened URL, and place it into the clipboard.

In Google Chrome, this would be pretty easy (according to http://developer.chrome.com/extensions/getstarted.html) -- pure JavaScript plus a few calls to JavaScript API-s of interacting with the browser&#39;s UI.

However, after searching around for a good Firefox extensions tutorial, the most officially-looking links I found are:

 * https://developer.mozilla.org/en-US/docs/Extensions
 * https://developer.mozilla.org/en-US/docs/Building_an_Extension
 * https://stackoverflow.com/questions/24772/how-do-i-write-a-firefox-addon

According to them, it looks like I will have to learn the XUL language for even the simplest interactions with the browser&#39;s UI. On top of that, I will have to set up custom Firefox profile so as not to hose my default profile during development, create complicated directory structure, write manifest in obscure XML, figure out how to package and test whatever I implement, etc.

It&#39;s 2013, isn&#39;t there an easier way of building Firefox extensions?

Recently I&#39;ve realised that, some adblocker extensions (such as adBlocker plus) block some Ajax calls. I get that error on the console:

    GET http://localhost/prj/conn.php?q=users/list/ net::ERR_BLOCKED_BY_CLIENT 

Why does it block some Ajax call but not the others and what causes that? Is there any workaround other than telling user to turn off adblocker?

Reference: [FileReader.readAsDataURL](https://developer.mozilla.org/en-US/docs/Web/API/FileReader.readAsDataURL)

Considering the following example:

    function previewFile(file) {
      
      var reader  = new FileReader();
    
      reader.onloadend = function () {
        console.log(reader.result);

&gt; 
&gt; blob: The Blob or File from which to read.

 1. How can a local file URL like: `&#39;file:///C:/path-to/root.png&#39;` be
    passed to the `readAsDataURL()`   
 
 2. Is `FileReader()` available in a Firefox Addon?

**EDIT**
After looking at JSHint I found this &#39;**destructuring expression&#39; is available in ES6 (use esnext option) or Mozilla JS extensions (use moz)** and [this][1]  however after reading it I still don&#39;t understand why it is used 


I have come across the following code on [MDN][2]


    
    var ui = require(&quot;sdk/ui&quot;);
    var { ActionButton } = require(&quot;sdk/ui/button/action&quot;);
What do the braces on the second line do and why are they used? Why are there no braces on the first line?
