java中rest API的身份验证失败错误

Question

我正在使用以下代码执行一些请求：

    DefaultHttpClient httpclient = new DefaultHttpClient();
    httpclient.getCredentialsProvider().setCredentials(
                new AuthScope("testrail.xyz.com", 80), 
                new UsernamePasswordCredentials("[e-mail]", "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));
      }

我收到的答复是：

执行http://testrail.mypublisher.com:80请求

----------------------------------------

HTTP/1.1 401未授权日期：周三，11月4日2015 17:19:05GMT服务器：Apache X-Powerd-By：PHP/5.3.3 Content-Llong：87连接：关闭Content-Type：Application/json；charset=utf-8

----------------------------------------

{“error”：“身份验证失败：用户/密码或会话cookie无效或丢失。”}

我通过了身份验证的凭据，但仍然收到此错误。当我手动登录应用程序或通过Firefox Rest客户端触发上述请求时，它可以正常工作。我哪里出错了？我使用的是4.5.1 httpClient jar文件。

尝试以下操作（来自Apache HTTPClient文档）：

/**
 * 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();
        }
    }
}
