AngularJS $http.get which contains a parameter with null value

Question

I've got a strange issue and can't figure it out. When I'm calling $http.get with params like

{oneId: 111
 twoId: 222
 stringValue: null}

then stringValue is absent and the request goes like

http://my-uri.com/action?oneId=111&twoId=222

But if stringValue setted as undefined then it goes ok. What's wrong there?

Answer 1

null is a reserved keyword, that's why it's behaving like that. You can resolve this in a number of way -

1. as you are using asp.net web api - you can re-write your action -

public IHttpActionResult someAction(long oneId, long twoId, string stringValue = null)

In this way if stringValue doesn't get passed in param, then it will be received as null.

2. you can send null as string int the get method -

{oneId: 111
 twoId: 222
 stringValue: "null"}

Sending an empty string("") instead of "null" is also an option.

3. Also as per this answer - sending url encoded null value(%00) will also work.
