I'm trying to grab the IP of users.
I followed guides on how to do this, and found answers that use event.source_ip in the lambda function, which connects to the API Gateway.
The result returns 'null' in my Lex & Facebook bots, and returns 'test-invoke-source-ip' in the API Gateway Test.
Lambda:
exports.handler = (event, context, callback) => {
callback(null, event.source_ip);
};
API Gateway: Integration Request
Use lambda proxy integration, then you can handle the event and context from the lamda function yourself. You can read more here. https://docs.aws.amazon.com/apigateway/latest/developerguide/set-up-lambda-proxy-integrations.html
You will need to return expected output for it to work.
Example using node (untested):
exports.handler = (event, context, callback) => {
var res = {
"statusCode": 200,
"body": context.identity.sourceIp,
"isBase64Encoded": false,
}
callback(null, res);
}
