认证具有的HttpClient 4.x的一个请求 [英] Authenticating a single request with httpclient 4.x

问题描述

我有一个是由多个线程共享一个的HttpClient 实例。我想用它做一个身份验证的请求。由于只有单个的请求，应进行身份验证，我不想作为<一个描述修改的HttpClient 实例href=\"http://svn.apache.org/repos/asf/httpcomponents/httpclient/branches/4.0.x/httpclient/src/examples/org/apache/http/examples/client/ClientAuthentication.java\"相对=nofollow>文档。以下是我已经计算出，而不是，这是行不通的。从我可以告诉，它看起来并不像 CredentialsProvider 正在使用的。任何提示？

  HttpContext的背景下= NULL;
如果（feedSpec.isAuthenticated（））{
  上下文=新BasicHttpContext（）;
  CredentialsProvider credsProvider =新BasicCredentialsProvider（）;
  credsProvider.setCredentials（AuthScope.ANY，新UsernamePasswordCredentials（feedSpec.getHttpUsername（），feedSpec.getHttpPassword（）））;
  context.setAttribute（ClientContext.CREDS_PROVIDER，credsProvider）;
  context.setAttribute（ClientPNames.HANDLE_AUTHENTICATION，真）;
}
HTTPGET HTTPGET =新HTTPGET（feedSpec.getUri（））;
HTT presponse HTT presponse = httpClient.execute（HTTPGET，背景）;
 

解决方案

原来我是连接到只提供NTLM身份验证服务器。我使用指南 rel=\"nofollow\">实施NTLM身份验证。我修改我的问题列出的code看起来像这样和它的作品：

  HttpContext的背景下= NULL;
如果（feedSpec.isAuthenticated（））{
    上下文=新BasicHttpContext（）;
    CredentialsProvider credsProvider =新BasicCredentialsProvider（）;
    credsProvider.setCredentials（AuthScope.ANY，新NTCredentials（feedSpec.getHttpUsername（），feedSpec.getHttpPassword（），，））;
    context.setAttribute（ClientContext.CREDS_PROVIDER，credsProvider）;
}
HTTPGET HTTPGET =新HTTPGET（feedSpec.getUri（））;
HTT presponse HTT presponse = httpClient.execute（HTTPGET，背景）;
 

I have an HttpClient instance that's shared by a number of threads. I would like to use it to make a single authenticated request. Because only the single request should be authenticated, I don't want to modify the HttpClient instance as described in the documentation. Here's what I've worked out instead, which isn't working. From what I can tell, it doesn't look like the CredentialsProvider is being used at all. Any tips?

HttpContext context = null;
if(feedSpec.isAuthenticated()) {
  context = new BasicHttpContext();
  CredentialsProvider credsProvider = new BasicCredentialsProvider();
  credsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(feedSpec.getHttpUsername(), feedSpec.getHttpPassword()));
  context.setAttribute(ClientContext.CREDS_PROVIDER, credsProvider);
  context.setAttribute(ClientPNames.HANDLE_AUTHENTICATION, true);
}
HttpGet httpGet = new HttpGet(feedSpec.getUri());
HttpResponse httpResponse = httpClient.execute(httpGet, context);

解决方案

It turns out the server I was connecting to was only offering NTLM authentication. I implemented NTLM authentication using the guide here. I modified the code listed in my question to look like so and it works:

HttpContext context = null;
if(feedSpec.isAuthenticated()) {
    context = new BasicHttpContext();
    CredentialsProvider credsProvider = new BasicCredentialsProvider();
    credsProvider.setCredentials(AuthScope.ANY, new NTCredentials(feedSpec.getHttpUsername(), feedSpec.getHttpPassword(), "", ""));
    context.setAttribute(ClientContext.CREDS_PROVIDER, credsProvider);
}
HttpGet httpGet = new HttpGet(feedSpec.getUri());
HttpResponse httpResponse = httpClient.execute(httpGet, context);
