Www.text returns weird value in Unity3D (C #)

Question

I use Unity 3D WWW to create http requests: http://docs.unity3d.com/ScriptReference/WWW.html

It seems that no matter what data I try to get, it just returns: every time. I tried json files, I tried php, which just generates a string. I cannot access the values ​​on the server.

WITH#:

public string url = "http://www.onelittledesigner.com/data.php"; IEnumerator Start() { WWW www = new WWW(url); yield return www; if (!string.IsNullOrEmpty(www.error)) { Debug.Log(www.error); } else { Debug.Log(www.text); } } 

PHP:

 <?php echo "textiness"; ?> 

---

Note: I used www.texture to delete images from the server. However, www.text does not seem to work.

Copy response from comment with some additional tests. My results are given in the comments. Please note that using default, ASCII or UTF8 really works on my machine - it should also be on yours.

  // returned from www.bytes, copied here for readability byte[] bytes=new byte[]{116, 101, 120, 116, 105, 110, 101, 115, 115}; string customDecoded=""; foreach(var b in bytes) customDecoded+=(char)b; Debug.Log(customDecoded); // textiness Debug.Log(System.Text.Encoding.Default); // System.Text.ASCIIEncoding Debug.Log(System.Text.Encoding.Default.GetString(bytes)); // textiness Debug.Log(System.Text.Encoding.ASCII.GetString(bytes)); // textiness Debug.Log(System.Text.Encoding.Unicode.GetString(bytes)); // 整瑸湩獥Debug.Log(System.Text.Encoding.UTF7.GetString(bytes)); // textiness Debug.Log(System.Text.Encoding.UTF8.GetString(bytes)); // textiness Debug.Log(System.Text.Encoding.UTF32.GetString(bytes)); // 整湩Debug.Log(System.Text.Encoding.BigEndianUnicode.GetString(bytes)); // 瑥硴楮敳 

Please check if System.Text.Encoding.Default ASCIIEncoding, maybe something changed the default value?

My answer suggests that this script is attached to MonoBehaviour. The reason it doesn't work is because you tried to turn the Start method into a collaborative procedure, but only half done it.

Here is what you need to do

 private void Start() { StartCoroutine(StartCR()); } IEnumerator StartCR() { WWW www = new WWW(url); yield return www; if (!string.IsNullOrEmpty(www.error)) { Debug.Log(www.error); } else { Debug.Log(www.text); } } 

Unity will call the Start method, which in turn will correctly call your co-programmed WWW code. This will wait for your web response to complete, instead of just returning nothing.
