Query Params include #, Javascript (Node) errors out

Question

To keep this simple, I am using Firebase Cloud Functions, and when/if I receive a param that contains a #, it doesn't recognize it.

For example: http://example.net?id=123#456. if I log the id, ill only get 123.

However, if I do something like http://example.net?id=123456, everything will be logged.

How can I include the # sign with the string value for id?

Better Detail:

URL: http://example.com?item=2019+#157&typeOfListing=sold

If I encode the request query

let item = encodeURIComponent(req.query.item);

I will get the following:

2019%20

It is not taking the # with it.

thats part of the hash of the url. you have to encode it. can you provide exactly the input and outputs and the workings of your code for details? — Daniel A. White, Jul 28 '20 at 19:52

That's because # is a special character in urls (just like /, :, ?, ... are), it's used to denote the fragment part of the url. You need to escape it using encodeURIComponent like so:

let idParam = encodeURIComponent("123#456");
let url = "http://example.net?id=" + idParam;

This isnt including the # sign. – letsCode Jul 28 '20 at 20:06
@soldfor you are on server side? The query param needs to be encoded on the side that generated the request. – ibrahim mahrir Jul 28 '20 at 20:13
so if its coming from an app (android, ios), it needs to be encoded on the client. – letsCode Jul 28 '20 at 20:14
@soldfor exactly. the hash generally isn't sent to the server – Daniel A. White Jul 28 '20 at 20:14
@soldfor yes, otherwise [it is never sent to server](https://stackoverflow.com/a/43280710/9867451). The app that sends the request should encode all special characters in the url before making the request – ibrahim mahrir Jul 28 '20 at 20:15
or deny them all together... which i probably rather. thanks for the help man. – letsCode Jul 28 '20 at 20:17
@soldfor you're welcome, buddy! Glad I could help :-) – ibrahim mahrir Jul 28 '20 at 20:18
