Short Overview.
I host an Angular Application on an S3 Bucket. I also got an Cloudfront distribution to handle HTTPS and Redirects.
I try to form an querystring parameter depending on which URL the user is connecting to.
2 examples
test.example.com --> example.com?id=test
hello.example.com --> example.com?id?hello
So far i tried to implement an AWS lambda@Edge Function but nothing worked so far. If i try to manipulate the request it wont have any effects, if i try to manipulate the response the redirect does not work and i get an S3 bucket error or Cloudfront error.
'use strict';
const remove_suffix = '.example.com';
exports.handler = (event, context, callback) => {
const request = event.Records[0].cf.request;
const headers = request.headers;
const host_header = headers.host[0].value;
if(host_header.endsWith(remove_suffix)){
request.querystring = 'id=' + host_header.substring(0,host_header.length - remove_suffix.length);
}
return callback(null,request);
};
1) Which trigger should I use?
2) Which settings could I be missing on Cloudfront settings?
3) Is my Lambda function wrong?
