Question by timkulp · Aug 28, 2017 at 01:01 AM · webservice

Zero byte post

Hello,

I am working with a web API that requires a zero byte post. In my research I'm seeing there is not a way to do that but wanted to ping the team here to see if anyone's had a creative solution. I was looking at this post: http://answers.unity3d.com/questions/340236/error-when-creating-request-post-request-with-a-ze.html and saw that I'm not the only person running into this issue. Unfortunately, the web API I'm trying to use doesn't like the proposed solution in that post.

Here's my code (pretty basic):

 WWWForm form = new WWWForm();
 Dictionary<string,string> headers = form.headers;
 headers["Authorization"] = "Bearer " + Secret;
 WWW www = new WWW(APIUrls.Urls["TokenGenerate"], form.data, headers);
 yield return www;

I have tried sending in fake fields, zero byte arrays, empty lines, spaces, etc... but nothing is working except an empty body. Specifically, I get a BAD REQUEST error for anything other than an empty body. I have validated this via Fiddler as well. Any advice would be greatly appreciated!

My next thought is to create a proxy service that will accept a body and then relay to the API I want to use but before I do all that, I wanted to check in here.

Thank you!

I took a different approach to achieve a zero byte POST using WebRequest (System.Net). This works for the POST I was looking for. I've read this will have issues with WebGL but my app isn't going to WebGL so I think this will be fine. If anyone has thoughts on why I shouldn't go that path please feel free to let me know.
