Unity3D WWW错误C＃

Question

我团结奋斗试图弄清楚从online-go.com

的WWW类和访问API我在得到的debug.log一个错误，但。此外，58行调试只是返回一个空白字符串。我不认为我完全理解如何使用WWW，因为这是我第一次使用它。

必要的数据倒带是不可能 UnityEngine.Debug:Log(Object) <LoadWWW>c__Iterator0:MoveNext()（在资产/ OGS.cs：60）

Answer 1

necessary data rewind wasn't possible当WWW呼叫期间参与重定向主要发生。

要解决此问题，请确保您调用的URL不会将您重定向到过程中的另一个页面。另外，在使用该值之前进行一些错误处理是一个好主意。

// wait for the result 
yield return text; 

// Handle the error if there is any 
if (!string.IsNullOrEmpty(text.error)) { 
    Debug.Log(text.error); 
} 
// Now do with POSTResponse whatever you want if there were no errors.
