驗證失敗的錯誤休息API在Java中

Question

我使用下面的代碼來執行一些要求：

DefaultHttpClient httpclient = new DefaultHttpClient(); 
    httpclient.getCredentialsProvider().setCredentials(
       new AuthScope("testrail.xyz.com", 80), 
       new UsernamePasswordCredentials("abc@xyz.com", "test123")); 

    try { 
     // specify the host, protocol, and port 
     HttpHost target = new HttpHost("testrail.xyz.com", 80, "http"); 

     // specify the get request 
     HttpGet getRequest = new HttpGet("/index.php?/api/v2/get_runs/52"); 
     getRequest.addHeader("Content-Type", "application/json;charset=UTF-8"); 

     System.out.println("executing request to " + target); 

     HttpResponse httpResponse = httpclient.execute(target, getRequest); 
     HttpEntity entity = httpResponse.getEntity(); 

     System.out.println("----------------------------------------"); 
     System.out.println(httpResponse.getStatusLine()); 
     Header[] headers = httpResponse.getAllHeaders(); 
     for (int i = 0; i < headers.length; i++) { 
     System.out.println(headers[i]); 
     } 
     System.out.println("----------------------------------------"); 

     if (entity != null) { 
     System.out.println(EntityUtils.toString(entity)); 
     } 

，我收到的迴應：

執行請求http://testrail.mypublisher.com:80

我傳遞憑據進行身份驗證，我仍然得到這個錯誤。當我手動登錄到應用程序或燒透Firefox的REST客戶端的上述要求，它工作正常。 我哪裏錯了？ 我使用4.5.1 HttpClient的jar文件。

試試這個（Apache的文檔的HTTPClient）：

/** 
* A simple example that uses HttpClient to execute an HTTP request against 
* a target site that requires user authentication. 
*/ 
public class ClientAuthentication { 

    public static void main(String[] args) throws Exception { 
     CredentialsProvider credsProvider = new BasicCredentialsProvider(); 
     credsProvider.setCredentials(
       new AuthScope("httpbin.org", 80), 
       new UsernamePasswordCredentials("user", "passwd")); 
     CloseableHttpClient httpclient = HttpClients.custom() 
       .setDefaultCredentialsProvider(credsProvider) 
       .build(); 
     try { 
      HttpGet httpget = new HttpGet("http://httpbin.org/basic-auth/user/passwd"); 

      System.out.println("Executing request " + httpget.getRequestLine()); 
      CloseableHttpResponse response = httpclient.execute(httpget); 
      try { 
       System.out.println("----------------------------------------"); 
       System.out.println(response.getStatusLine()); 
       System.out.println(EntityUtils.toString(response.getEntity())); 
      } finally { 
       response.close(); 
      } 
     } finally { 
      httpclient.close(); 
     } 
    } 
}
