I cant get response json from rest call in Unity

Question

Hi all,

I had a problem while using www class for rest calls. I wrote the following code.

        void Start () 
        {
              WWW www = new WWW ("http://ip.jsontest.com/");
              StartCoroutine(WaitForRequest (www));
         }

         private IEnumerator WaitForRequest(WWW www) 
         {

              yield return www;

              // check for errors
              if (www.error == null) {
                 print (www.text);
              } else {
                     print ("error: "+www.error);
              }
         }

"http://ip.jsontest.com/" this url returns simple json that shows an ip.

Ex: { "ip": "193.202.18.14" }

But I didnt get that json in unity. What i get is below.

         <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"             "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
         <html xmlns="http://www.w3.org/1999/xhtml">
         <head>
         <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
         <title>IIS Windows Server</title>
         <style type="text/css">
         <!--
         body {
             color:#000000;
             background-color:#0072C6;
             margin:0;
         }

         #container {
             margin-left:auto;
             margin-right:auto;
             text-align:center;
             }

         a img {
             border:none;
         }

         -->
         </style>
         </head>
         <body>
         <div id="container">
         <img src="iis-85.png" alt="IIS"  />
         </div>
         </body>
         </html>
         UnityEngine.MonoBehaviour:print(Object)
         <WaitForRequest>c__Iterator0:MoveNext() (at Assets/ApplicationController.cs:56)
         UnityEngine.SetupCoroutine:InvokeMoveNext(IEnumerator, IntPtr)

I have read many documents and I have tried many solutions but I couldn't solve it. How could i get that json?

Thanks,

At first I wanted to suggest the things below the line, but now I think you have some local problem. Did you try the same request using curl or any other program? I thought the headers might be the problem, but both curl and a request from within java HTTPUrlConnection return the expected contents.

I don't know what you have tried yet and cannot test it here, but you could try a different constructor to pass an "Accept: application/json" header value.

To keep it a GET request, check out this answer:

Yes, you are right it is a local problem. I didn't realize it before because i could send request via rest client tools such as "postman". But I realized that Firewall or proxy settings blocking my request. Now it works like a charm. Thanks.
