You might be looking for the invoke url,&lt;br&gt;&lt;br&gt;
1. go to https://console.aws.amazon.com/apigateway&lt;br&gt;&lt;br&gt;
2. select **api link** (which you have deployed on aws lambda).&lt;br&gt;

3. select **stages** in left side panel and
see the **invoke url**.

Adding a http listener can be done by going to your lambda function, selecting the &#39;triggers&#39; tab and &#39;add trigger&#39;, finally selecting API Gateway - but as others mentioned this does create a public facing url.

Duh, I was in the wrong AWS logon previously so the API GW was not showing any matching Serverless API and that was why I couldn&#39;t understand how they did it...

Once I logged into the AWS account that hosts the Serverless structure I can see the API GW GET API&#39;s for the Serverless HTTP listener.

I made a change on one of the `.js` files that I use and no matter what I do, flask insists on picking up, from memory cache, the last version of the file, without the change.

To clarify, I have the following structure. It all starts with `foo.html`

    return render_template foo.html

`foo.html` has a form inside that  calls flask with some data and then returns a second template `bar.html`:

    return render_template bar.html

This second template calls some `.js` file, placed in the `static` folder, but it doesn&#39;t update when the code changes.


I mention the structure above because if the `.js` file was placed on `foo.html` instead of `bar.html` then Flask **would** pick up the new changes on the file. But in `bar.html` Flask completely ignores them.

What is happening? 

The only thing that worked was to click on &quot;disable cache&quot; on the browser and reload again.

I am unable to rotate the image by 90 degrees in swift. I have written below code but there is an error and doesn&#39;t compile

      func imageRotatedByDegrees(oldImage: UIImage, deg degrees: CGFloat) -&gt; UIImage {

        //Calculate the size of the rotated view&#39;s containing box for our drawing space
        let rotatedViewBox: UIView = UIView(frame: CGRect(x: 0, y: 0, width: oldImage.size.width, height: oldImage.size.height))
        let t: CGAffineTransform = CGAffineTransform(rotationAngle: degrees * CGFloat(M_PI / 180))
        rotatedViewBox.transform = t
        let rotatedSize: CGSize = rotatedViewBox.frame.size

        //Create the bitmap context
        UIGraphicsBeginImageContext(rotatedSize)
        let bitmap: CGContext = UIGraphicsGetCurrentContext()!

        //Move the origin to the middle of the image so we will rotate and scale around the center.
        bitmap.translateBy(x: rotatedSize.width / 2, y: rotatedSize.height / 2)

        //Rotate the image context
        bitmap.rotate(by: (degrees * CGFloat(M_PI / 180)))

        //Now, draw the rotated/scaled image into the context
        bitmap.scaleBy(x: 1.0, y: -1.0)
        bitmap.draw(oldImage, in:  CGRect(origin: (x: -oldImage.size.width / 2,  y: -oldImage.size.height / 2, width:  oldImage.size.width, height: oldImage.size.height), size: oldImage.cgImage))
        
        let newImage: UIImage = UIGraphicsGetImageFromCurrentImageContext()!
        UIGraphicsEndImageContext()

        return newImage

      }

below is the code i am not sure about

    bitmap.draw(oldImage, in:  CGRect(origin: (x: -oldImage.size.width / 2,  y: -oldImage.size.height / 2, width:  oldImage.size.width, height: oldImage.size.height), size: oldImage.cgImage))

I am fairly new to `AWS Lambda` but sure can see the benefits of it and stumbled upon the superb framework `Serverless` to help me built solutions on Lambda.

I started out building solutions using `AWS API` Gateway but really need `&quot;internal&quot; VPC API`&#39;s and not public Internet facing API&#39;s like API GW creates.

I found that `Servless` indeed can expose a `HTTP` endpoint but I can&#39;t figure out how this is done and how the URL is created.
When I deploy the Lambda from Serverless it gives me the URL, e.g.:

https://uxezd6ry8z.execute-api.eu-west-1.amazonaws.com/dev/ping

I would like to be able to find (or create) this same http listener for already existing `Lambdas` so my question is how is the `URL` created and where is teh actual `HTTP` listener deployed?

I am fairly new to <code>AWS Lambda</code> but sure can see the benefits of it and stumbled upon the superb framework <code>Serverless</code> to help me built solutions on Lambda.

I am trying to create a lambda service on AWS and have it accessed from outside via the API gateway with no authentication or restriction required.

To make things easy I set the gateway for now to be a Mock.

On the Get method of the API, the Authorization is set to `None` and the API Key is `not required`.

When I try this, I get `{&quot;message&quot;:&quot;Forbidden&quot;}`
(same message if I connect it to the actual lambda service). 

Any advice on how to make it accessible?

The AWS has introduced Environment variables for accessing in the Lambda function. I could not find any documentation which shows how to access the environment variables from the Lambda function using Java. Can anyone help me?

Accessing AWS Lambda environment variables in Java code

Today I have a new AWS Lambda question, and can&#39;t find anywhere in Google.

I new a Lambda function, there is no question.
But when I input any code in this function[eg. console.log();] and click  &quot;Save&quot;, error is occured:
&quot;The provided execution role does not have permissions to call DescribeNetworkInterfaces on EC2&quot; 

    exports.handler = (event, context, callback) =&gt; {
        callback(null, &#39;Hello from Lambda&#39;);
        console.log();  // here is my code   
    }; 

I bound the function with Role: lambda_excute_execution(Policy:AmazonElasticTranscoderFullAccess)
And this function is not bound with any triggers now.

And then, I give the role &quot;AdministratorAccess&quot; Policy, I can save my source code correctly.

This role can run Functions successfully before today.

Is anyone know this error?

Thanks Very much!

I created a lambda function in AWS (Python) using &quot;upload .zip&quot;
I lost those files and I need to make some changes, is there is any way to download that .zip?

Using the new [environment variable support in AWS Lambda](http://docs.aws.amazon.com/lambda/latest/dg/env_variables.html), I&#39;ve added an env var via the webui for my function.

How do I access this from Python? I tried:

    import os
        
    MY_ENV_VAR = os.environ[&#39;MY_ENV_VAR&#39;]

but my function stopped working (if I hard code the relevant value for `MY_ENV_VAR` it works fine).

How to access an AWS Lambda environment variable from Python

I have an AWS api that proxies lamba functions. I currently use different endpoints with separate lambda functions:

    api.com/getData --&gt; getData
    api.com/addData --&gt; addData
    api.com/signUp --&gt; signUp

The process to manage all the endpoints and functions becomes cumbersome. Is there any disadvantage when I use a single endpoint to one lambda function which decides what to do based on the query string?

    api.com/exec&amp;func=getData --&gt; exec --&gt; if(params.func === &#39;getData&#39;) { ... }

What do you think are the Pros and Cons of using Lambda integration with and without the proxy feature in AWS API Gateway (and more specifically, when using the Serverless framework)? Here&#39;s what I think up to now:

**Lambda Integration with Proxy**

 - **Pro**: One can rapidly prototype and code without worrying about all the needed configuration details (and reinventing a few wheels like generic template mappings, etc).
 - **Pro**: It&#39;s really easy to return any status code and custom headers, while at the same time there&#39;s a generic way to read the body, headers, parameters, of the request.
 - **Con**: Everything is done in code, so autogenerating documentation is a bit more difficult. Dependencies (headers, models, returned status codes) are &quot;hidden&quot; in the code.

**Lambda Integration without Proxy**

 - **Con**: Involves *a lot* more of work to set it up, and this configuration might be duplicated in different resources.
 - **Pro**: It allows one to decouple what the lambda receives and returns, and how it gets mapped to different HTTP status codes, headers, and payloads.
 - **Pro**: Very useful because it stipulates upfront what it returns, and what it requires in terms of headers and payloads.
 - **Pro**: The hard work when setting up everything is useful in the long run because one can export everything to Swagger, so others can use this to generate different SDKs for it.

What are your thoughts? Do you generally use Lambda Proxy or plain Lambda integrations? What do you prefer, and why?

**EDIT**: So far, I&#39;m inclined to always choose not to use the proxy features due to the reasons mentioned (decoupling and stating dependencies -headers, status codes, etc- upfront).

Lambda Integration vs. Lambda Proxy: Pros and Cons

I&#39;m finding it hard to understand the difference between SAM template and Cloudformation template. I know that SAM template can be used to define Serverless Applications like Lambda, but how does that make it different from Cloudformation template? Is the syntax different? I can still specify the Lambda definitions in cloudformation template. So, my question is why should I care about SAM? Won&#39;t knowing about just cloud formation template be sufficient?

I&#39;m working on a aws serverless project and need to test the lambda functions locally.
&lt;br&gt;
I am using `serverless invoke local -f {function_name}` command to test the API calls that does not request any path or query parameters.
&lt;br&gt;
My question is how can I use this command to pass any path or query parameter to the function?

***Example serverless description***

    getFoodDetails:
        handler: handler.getFoodDetails
        events:
          - http:
              method: get
              path: /foods/{food_id}
              cors: true
              request:
                parameters:
                  paths:
                    food_id: true
