I am using html script tag to ping AWS gateway endpoint to trigger a function in AWS lambda.
In this lambda function, I need to retrieve the original client's full url. I can get referer data but can't figure out how to get the full url.
I tried to see if there is "origin" info in "event" object but there is no such data.
exports.handler = async (event, context) => {
return {
statusCode: 200,
body: "console.log(" +JSON.stringify(event) +","+JSON.stringify(context) +")"
};
}
Here is the client code that pings the http api gateway index.html
<html>
<script src="http api gateway endpoint" defer async />
<body></body>
</html>
Now how can I get the client full url in lambda function?
The information sent in a referrer header is restricted for security reasons. You can adjust this with a header or the referrerpolicy attribute.
Note that the <script> element is not a void element. The end tag is mandatory.
<script src="http api gateway endpoint" defer async referrerpolicy"unsafe-url"></script>
You could also generate the <script> element dynamically and pass data from window.location in the query string.
