我有,我想其他.NET應用程序使Web請求發送到Web API服務,但是我發現了以下錯誤這樣做時:的Web請求的.NET Web API服務得到401未經授權錯誤

」遠程服務器返回錯誤:(401)未經授權。「

只是爲了澄清,這些是2個獨立的.net應用程序試圖溝通。

下面是客戶端的.Net C#應用程序試圖使Web請求到其他Web API服務的代碼:

public string MakeWebRequest() 
    { 
     var requestUrl = "http://localhost:8081/api/Tests/results"; 

     var request = WebRequest.Create(requestUrl); 
     var username = "test"; 
     var password = "test"; 
     SetBasicAuthHeader(request, username, password); 

     var postData = "thing1=hello"; 
     postData += "&thing2=world"; 
     var data = Encoding.ASCII.GetBytes(postData); 

     request.Method = "POST"; 
     request.ContentType = "application/json"; 
     request.ContentLength = data.Length; 
     //request.Expect = "application/json"; 

     using (var stream = request.GetRequestStream()) 
     { 
      stream.Write(data, 0, data.Length); 
     } 

     string text; 
     var response = (HttpWebResponse)request.GetResponse(); 

     using (var sr = new StreamReader(response.GetResponseStream())) 
     { 
      text = sr.ReadToEnd(); 
     } 

     return null; 
    } 

    public static void SetBasicAuthHeader(WebRequest request, String userName, String userPassword) 
    { 
     string authInfo = userName + ":" + userPassword; 
     authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo)); 
     request.Headers["Authorization"] = "Basic " + authInfo; 
    } 

而這裏的淨C#的Web API服務的代碼時,應該接收從其他應用程序的網絡請求:

[RoutePrefix("api/Tests")] 
public class TestsApiController : ApiController 
{ 
    [POST("results")] 
    [AcceptVerbs("POST")] 
    [HttpPost] 
    [BasicAuthAuthorize(Roles="Admin")] 
    public JObject resultsFinished() 
    { 
    //do something 
    } 
} 

而這裏的基本認證的屬性我創建的,它甚至不會從客戶服務的打擊。

public class BasicAuthAuthorizeAttribute : AuthorizeAttribute 
{ 
    private const string BasicAuthResponseHeader = "WWW-Authenticate"; 
    private const string BasicAuthResponseHeaderValue = "Basic"; 

    public override void OnAuthorization(HttpActionContext actionContext) 
    { 
     try 
     { 
      AuthenticationHeaderValue authValue = actionContext.Request.Headers.Authorization; 

      if (authValue != null && !String.IsNullOrWhiteSpace(authValue.Parameter) && authValue.Scheme == BasicAuthResponseHeaderValue) 
      { 
       var parsedCredentials = ParseAuthorizationHeader(authValue.Parameter); 

       if (parsedCredentials != null) 
       { 
        if (parsedCredentials.Username == IoC.Username && parsedCredentials.Password == IoC.Password) 
         return; 
       } 
      } 
     } 
     catch (Exception) 
     { 
      //actionContext.Response = actionContext.Request.CreateResponse(HttpStatusCode.Unauthorized); 
      actionContext.Response.Headers.Add(BasicAuthResponseHeader, BasicAuthResponseHeaderValue); 
      return; 

     } 
    } 

    private Credentials ParseAuthorizationHeader(string authHeader) 
    { 
     string[] credentials = Encoding.ASCII.GetString(Convert.FromBase64String(authHeader)).Split(new[] { ':' }); 

     if (credentials.Length != 2 || string.IsNullOrEmpty(credentials[0]) || string.IsNullOrEmpty(credentials[1])) 
      return null; 

     return new Credentials() { Username = credentials[0], Password = credentials[1], }; 
    } 
} 
//Client credential 
public class Credentials 
{ 
    public string Username { get; set; } 
    public string Password { get; set; } 
}

是我還是你發送**通過HTTP原始明文密碼* * –

抱歉忘記包含更多編碼密碼的代碼。上面的通知編輯。謝謝! – jre247

Web服務中可以運行「HelloWorld」或「Test」方法嗎?這可能是運行該服務的應用程序池的id的問題。 – Duston

嘗試使用諸如Fiddler一個工具來解決什麼被髮送到Web服務:?

我沒有看到任何與客戶端應用程序向服務器應用程序發出請求有關的小提琴手。 :( – jre247

所有的提琴手將看到的是從服務器回來的401錯誤 – Duston

@Duston由於某種原因提琴手沒有顯示任何與401.相關的任何想法? – jre247
