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。 这在团结中非常有效。 但不是在andoird ，一旦生成了apk，它就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:ZZh7y6dn@*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清单权限

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"

出于安全原因，某些应用程序和操作系统不再支持在网址中嵌入用户名和密码（http://username:password@example.com）。这是因为这不是执行HTTP身份验证的标准方法。很可能Unity或Android没有实现这一点。

我使用http://Administrator:ZZh7y6dn@*IP Address*:8080/Thingworx/Things/SimulationData/Properties/OvenTemperature/在内置Android浏览器上对此进行了测试，但无法正常运行。所以，我猜这个问题来自Android。

我在没有用户名和密码http://*IP Address**:8080/Thingworx/Things/SimulationData/Properties/OvenTemperature/的情况下再次测试，然后出现了登录窗口。当我输入用户名和密码时，它有效。

您仍然可以使用UnityWebRequest来解决此问题，方法是使用AUTHORIZATION函数向UnityWebRequest提供SetRequestHeader标头。这仅在授权类型为Basic而非Digest时才有效。在您的情况下，它是HTTP Basic。

一般解决方案：

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();
    .......
}

问题中的解决方案：

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";
                }
            }
        }
    }
}

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