Cannot send POST data to Lambda

问题

I am trying to send data to my lambda function however the function is not getting my data, the event variable is empty. I am not getting any errors and when I test the function in my API Gateway it works fine. So I am not sure what is happening. My code for sending data to Lambda is below.

var options = { 
    method: 'POST', 
    url: 'correct api url', 
    contentType: "application/json",
    dataType: "json",
    data: s
}

for data: s within my console looks like this data: '{"article_url":"a url here"}'

Any idea what the problem is?

In the "Integration Request" configuration, make sure you've checked the "Use Lambda Proxy integration" checkbox.

And make sure your output matches the schema defined here to avoid errors:

http://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-set-up-simple-proxy.html#api-gateway-simple-proxy-for-lambda-output-format

{
    "isBase64Encoded": true|false,
    "statusCode": httpStatusCode,
    "headers": { "headerName": "headerValue", ... },
    "body": "..."
}
