I have an API in the AWS API gateway, connected to an AWS Lambda function in python, using lambda proxy integration. On my local computer, I am testing this API in python. I want to send a dictionary to the api and have the api return me a function of the elements in the dictionary.
The python code I use to test is:
import requests
import json
url = "https://p68yzl6gu6.execute-api.us-west-1.amazonaws.com/test/helloworld"
headers = {'data': [0,1]}
response = requests.post(url, json=headers)
print(response.text)
Since I cannot send a list through the header argument of requests.post I thought I'd use json. When I try this, I get a {"message": "Internal server error"}. This is my AWS lambda function (python):
import json
def lambda_handler(event, context):
return {
'statusCode': 200,
'body': event['data']
}
Looking at the logs, 'data' is not a key of event. How do I access the list in the AWS Lambda function? How do I find out what the event dictionary looks like when I test this? Looking forward I want to send a large dict containing dicts and lists. Is this the right way to do it?
Try
import json
def lambda_handler(event, context):
body = json.loads(event['body'])
return {
'statusCode': 200,
'body': json.dumps(body['data'])
}
