WWW class and HTTP Headers
Hi All,
Does anyone know if the WWW API will allow setting the HTTP headers for GET requests?
Thanks
No, it doesn't. If you read the docs on WWW you may have noticed that only the constructor with a single URL string will produce a GET request. All other versions use POST.
edit
I just had a look into the UnityEnigne.dll and it seems the single string argument constructor just uses WWW(url,null,null). So basically all use the same constructor. Now it depends on how Unity determines if it should send a POST or GET. Maybe they just look for the postData != null. So if you pass null it might send the request via GET. You have to try it yourself.
If you have new information, feel free to add an answer yourself that clears things up for others.
it didnt work. once i had a header value it changed to post. but thanks
That's a pity. Well, the only other way would be to use .NET / $$anonymous$$ono functions for the request. If you build for the webplayer, make sure the class / function is available and you provide a crossdomain-policy file.

@Bunny83, how did you looked inside it?
The key is leaving "postData" parameter to null. From Unity3D WWW reference
The WWW class will use GET by default and POST if you supply a postData parameter.
So this one works for me:
var form = new WWWForm();
var headers = new Hashtable();
headers.Add("Header_key", "Header_val");
www = new WWW("http://localhost/getpostheaders", null, headers);
yield return www;
Debug.Log("2. " + www.text);
The WWW class does not allow this. UniWeb does.
Using UniWeb comes with all sorts of other problems, such as having to setup a SocketPolicy listener on the server which requires another open port on the backend.
If you have control over your backend, I'd recommend changing it to support the given http endpoint using POST as well. It sucks and breaks the Restfulness if you'r backend api.
Unity not supporting custom headers for GETs really sucks.
