Load and save text from web server

Question

Hi all,

I'm doing an app for mobile, and i need to load text from web to use it after i unity.

So i would like to load the text and save it in a text asset (or .txt file).

There is my script :

 using UnityEngine;
 using System.Collections;
 
 public class http : MonoBehaviour {
     public string url = "http://www.mywebsite.com/largetextfile.txt";
     public float progress = 0;
     private string text;
 
     IEnumerator demarre() {
         WWW www = new WWW(url);
         yield return www;
         text = www.text;
     progress = www.progress;
 
         // how to save it in a file ?
 
     }
     
 
 }

When i debug (Debug.Log(www.text);)i have an error :

count <= std::numeric_limits::max() UnityEditor.DockArea:OnGUI() maxVertices < 65536 && maxIndices < 65536*3

Make sure that the "www.progress" part is completed 100% first.... and then you can call the following function. Stream reader and writer uses "System.IO" so you will have to make the header entry.

 void WriteIntoMyLocalFile(string textFromServerFile)
     {
     string filePath;
         
     filePath = Application.persistentDataPath + "/LocalLargeTextFile.txt";
         
         using (FileStream fs = new FileStream(filePath, FileMode.OpenOrCreate))
         {
             using (StreamWriter writer = new StreamWriter(fs))
             {                
                 writer.Write(textFromServerFile);
                 writer.Close();
                 writer.Dispose();
             }
             fs.Close();
             fs.Dispose();
     }        
     }

Use this function... This part of code is tested on iOS, Android and WP8. It was a bit tricky to read the content from web for me....but I see that you have already figured that out.

I use Application.persistent data path because it is convenient and consistent throughout all the platforms... you can use your resource directories as well but I have not tested working with them...

get the length of the text and see if it's over 16K characters. You might have a good string, but the editor might have problems displaying it to the debug log because it's too large.

As for saving it, easiest way is WriteAllText.
