data using AWS API Gateway and Lambda

I am trying to get the form data from a multipart/form-data POST to my ASW Lambda web service via API Gateway.

The HTTP POST has Content-Type "multipart/form-data" and body that is URL encoded. File data is also sent in this post (hence the multipart, I guess).

The web service needs to integrate with a thirdparty service, so changing the format of the POST isn't really an option.

I have seen this thread talking about converting the URL encoded data to JSON object for use in Lambda, but this doesn't do the trick.

I have also tried setting the Integration Request -> Mapping Templates for content type multipart/form-data to Input passthrough. This didn't help either.

I did come across another question about uploading a file using multipart/form-data , but since I'm not interested in the file, just the body, that answer didn't help.

Below find screenshot (sorry) of the captured post via runscope.

If the goal is to use Lambda, you'll need to pass valid JSON to the function. Currently there isn't a way to JSON-ify data inside Api Gateway that comes in as non-JSON data.

Our short term fix (on our backlog) is to provide a variable in the mapping templates to grab the raw input of the request. That way you could do a simple JSON conversion using a template like:

{
    "body" : "$input.body"
}

or something like that.

Check out the mapping template reference for more info: http://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-mapping-template-reference.html

Edit 4/7 - feature has been released as $input.body
