UnityWebRequest嵌入用于HTTP基本身份验证的用户密码数据不适用于Android

Question

以下代码用于从我们自己的系统中托管的Thingworx服务器获取温度值。 这在团结完美。 但不是在andoird中，一旦生成apk，它将不会从服务器获取任何数据，并且会建立连接。但是，它只是不会获取数据并将其放入文本网格中。

我使用统一5.4.1 32位。检查同时在Android - 5.0.2和6

using UnityEngine; 
using System.Collections; 
using UnityEngine.Networking; 
using System.Text.RegularExpressions; 
using System; 
using UnityEngine.UI; 

public class GETTempValue : MonoBehaviour { 


public GameObject TempText; 
static string TempValue; 

void Start() 
{ 
    StartCoroutine(GetText()); 
} 

IEnumerator GetText() 
{ 
    Debug.Log("Inside Coroutine"); 
    while (true) 
    { 
     yield return new WaitForSeconds(5f); 
     string url = "http://Administrator:[email protected]*IP Address*:8080/Thingworx/Things/SimulationData/Properties/OvenTemperature/"; 

     Debug.Log("Before UnityWebRequest"); 
     UnityWebRequest www = UnityWebRequest.Get (url); 
     yield return www.Send(); 
     Debug.Log("After UnityWebRequest"); 
     if (www.isError) { 
      Debug.Log ("Error while Receiving: "+www.error); 
     } else { 
      Debug.Log("Success. Received: "+www.downloadHandler.text); 
      string result = www.downloadHandler.text; 
      Char delimiter = '>'; 

      String[] substrings = result.Split(delimiter); 
      foreach (var substring in substrings) 
      { 
       if (substring.Contains ("</TD")) 
       { 
        String[] Substrings1 = substring.Split ('<'); 
        Debug.Log (Substrings1[0].ToString()+"Temp Value"); 
        TempValue = Substrings1 [0].ToString(); 
        TempText.GetComponent<TextMesh>().text = TempValue+"'C"; 
       } 
      } 
     } 

    } 

} 

} 

这是Android清单许可

uses-permission android:name="android.permission.INTERNET" 
uses-permission android:name="android.permission.CAMERA" 
uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" 
uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"

在URL中嵌入用户名和密码（http://username:[email protected]）在一些应用和操作系统不再支持出于安全原因。这是因为这不是执行HTTP身份验证的标准方式。 Unity或Android很可能没有实现这一点。

我在内置Android浏览器上用http://Administrator:[email protected]*IP Address*:8080/Thingworx/Things/SimulationData/Properties/OvenTemperature/进行了测试，结果失败。所以，我猜这个问题来自Android。

我再次测试没有用户名和密码http://*IP Address**:8080/Thingworx/Things/SimulationData/Properties/OvenTemperature/然后出现登录窗口。当我输入用户名和密码时，它工作。

你仍然可以使用UnityWebRequest通过提供AUTHORIZATION头到UnityWebRequest与SetRequestHeader功能来解决这个问题。这只适用于授权类型为Basic而不是Digest。在你的情况下，它是HTTP Basic。

对于一般的解决方案：

string authenticate(string username, string password) 
{ 
    string auth = username + ":" + password; 
    auth = System.Convert.ToBase64String(System.Text.Encoding.GetEncoding("ISO-8859-1").GetBytes(auth)); 
    auth = "Basic " + auth; 
    return auth; 
} 

IEnumerator makeRequest() 
{ 
    string authorization = authenticate("YourUserName", "YourPassWord"); 
    string url = "yourUrlWithoutUsernameAndPassword"; 


    UnityWebRequest www = UnityWebRequest.Get(url); 
    www.SetRequestHeader("AUTHORIZATION", authorization); 

    yield return www.Send(); 
    ....... 
} 

对于你的问题的解决方案：

public GameObject TempText; 
static string TempValue; 

void Start() 
{ 
    StartCoroutine(GetText()); 
} 

string authenticate(string username, string password) 
{ 
    string auth = username + ":" + password; 
    auth = System.Convert.ToBase64String(System.Text.Encoding.GetEncoding("ISO-8859-1").GetBytes(auth)); 
    auth = "Basic " + auth; 
    return auth; 
} 

IEnumerator GetText() 
{ 
    WaitForSeconds waitTime = new WaitForSeconds(2f); //Do the memory allocation once 

    string authorization = authenticate("Administrator", "ZZh7y6dn"); 
    while (true) 
    { 
     yield return waitTime; 
     string url = "http://*IP Address*:8080/Thingworx/Things/SimulationData/Properties/OvenTemperature/"; 


     UnityWebRequest www = UnityWebRequest.Get(url); 
     www.SetRequestHeader("AUTHORIZATION", authorization); 
     yield return www.Send(); 

     if (www.isError) 
     { 
      Debug.Log("Error while Receiving: " + www.error); 
     } 
     else 
     { 
      string result = www.downloadHandler.text; 
      Char delimiter = '>'; 

      String[] substrings = result.Split(delimiter); 
      foreach (var substring in substrings) 
      { 
       if (substring.Contains("</TD")) 
       { 
        String[] Substrings1 = substring.Split('<'); 
        Debug.Log(Substrings1[0].ToString() + "Temp Value"); 
        TempValue = Substrings1[0].ToString(); 
        TempText.GetComponent<TextMesh>().text = TempValue + "'C"; 
       } 
      } 
     } 
    } 
}
