Python Authorizer with API Gateway-CodePudding

I am trying to make a custom python authorizer with payload format 2.0, right now I'm keeping it really simple and just returning the json "{isAuthorized:true}" regardless of what token is presented.

However, I am still getting failures in cloudwatch saying that the format is incorrect..

I've tried "isAuthorized" as a simple response as well.

I am using the Simple response mode.

Here is the simple python authorizer:

import os
import re
import json
import logging
import base64
import boto3

def lambda_handler(event, context):
    try:
        response = "{isAuthorized:True}"
        y = json.dumps(response)
        return y;
    except:
        return "";

I've also tried it without the json.dumps like this:

...
try: 
    response = {"isAuthorized": True}
    return response;
...

Here's the error in CloudWatch:

The response from the Lambda Authorizer function doesn't match the format that API Gateway expects. Simple response did not include 'isAuthorized'

Any idea what I'm doing wrong?

CodePudding user response：

You are returning it as a string, which is not even a valid JSON.

You can try with:

        response = {"isAuthorized":True}
        y = json.dumps(response)

        y = {"isAuthorized":True}
