Unity3D WWW Fehler C#

Question

Ich arbeite in Unity versucht, die WWW-Klasse, um herauszufinden, und Zugang API von online-go.com

ich aber einen Fehler in der debug.log bekommen. Darüber hinaus gibt das Debug on Line 58 nur eine leere Zeichenfolge zurück. Ich glaube nicht, dass ich vollständig verstehe, wie man WWW benutzt, da dies das erste Mal ist, dass ich es benutze.

Notwendige Daten zurückspulen war nicht möglich UnityEngine.Debug:Log(Object) <LoadWWW>c__Iterator0:MoveNext() (bei Aktiva/OGS.cs: 60)

Answer 1

necessary data rewind wasn't possible hauptsächlich tritt auf, wenn die Umleitung während des WWW Anruf beteiligt ist.

Um dies zu beheben, stellen Sie sicher, dass die von Ihnen aufgerufene URL Sie nicht auf eine andere Seite im Prozess umleitet. Es wäre auch eine gute Idee, eine Fehlerbehandlung durchzuführen, bevor Sie den Wert verwenden.

// 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.
