Httpcomponents客户端代理问题

使用新httocomponent客户端模块Httpcomponents客户端代理问题

当试图通过代理连接到互联网，我有问题，如果我直接使用代理对象和HttpURLConnection的一切顺利：

URL u = new URL("http://www.google.com"); 
Proxy proxy = new Proxy(Type.HTTP, new InetSocketAddress("somehost", 8080)); 
HttpURLConnection con = (HttpURLConnection) u.openConnection(proxy); 
con.setRequestMethod("GET"); 
System.out.println(con.getResponseCode());

现在，我尝试做相同的新的API：

HttpHost proxy = new HttpHost("somehost", 8080, "http"); 
httpClient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy); 
HttpHost targetHost = new HttpHost("http://www.google.com"); 
HttpGet httpGet = new HttpGet("/"); 
try { 
    HttpResponse httpResponse = httpClient.execute(targetHost, httpGet); 
    System.out.println(httpResponse.toString()); 
} catch (Exception e) { 
    e.printStackTrace(); 
}

，但我得到这个：

HTTP/1.1 407 Proxy Authentication Required (Forefront TMG requires authorization to fulfill the request. Access to the Web Proxy filter is denied. ) [Via: 1.1 xxx, Proxy-Authenticate: Negotiate, Proxy-Authenticate: Kerberos, Proxy-Authenticate: NTLM, Connection: Keep-Alive, Proxy-Connection: Keep-Alive, Pragma: no-cache, Cache-Control: no-cache, Content-Type: text/html, Content-Length: 7079 ]

我也试过

ProxySelectorRoutePlanner routePlanner = new ProxySelectorRoutePlanner(
httpClient.getConnectionManager().getSchemeRegistry(),new MyProxySelector()); 
    httpClient.setRoutePlanner(routePlanner);

凡MyProxySelector返回我NNED代理，但没有结果。

为什么使用新API使代码内部需要代理认证？

我不知道为什么使用ProxySelectorRoutePlanner的解决方案不起作用，您确定使用代理设置启动您的JVM吗？

它看起来像你需要添加此行：

httpClient.getCredentialsProvider().setCredentials(new AuthScope("yourProxyHost", Port), 
      new UsernamePasswordCredentials("yourUsername", "yourPass"));
