Serverless Framework Python Lambda Return Json Directly

I'm trying to find out how can I return the response as a JSON directly using Serverless Framework. This is a function on AWS with Lambda Proxy Integration. All default setting. Th

Solution 1:

approach #1

Use json.dumps() to convert JSON to string.

import json
defhandle(event, context):
    log.info("Hello Wold")
    log.info(json.dumps(event, indent=2))
    return {
        "statusCode": 200,
        "body": json.dumps({"foo": "bar"}),
        "headers": {
            "Content-Type": "application/json"
        }
    }

approach #2

Use lambda integration and avoid json.dumps(). But this will transform your output as

{ foo = bar}

Solution 2:

The body needs to be stringified when working with API Gateway

The pythonish way to do it is to pass the JSON body into the json.dumps function.

defhandle(event, context):
  log.info("Hello Wold")
  log.info(json.dumps(event, indent=2))
  return {
      "statusCode": 200,
      "body": json.dumps({"foo": "bar"}),
      "headers": {
          "Content-Type": "application/json"
      }
  }
