如何在Java中的HttpClient请求上设置代理主机

我认为这可能会有所帮助：

HttpClient client = new HttpClient();HostConfiguration config = client.getHostConfiguration();config.setProxy("someProxyURL", "someProxyPort");Credentials credentials = new UsernamePasswordCredentials("username", "password");AuthScope authScope = new AuthScope("someProxyURL", "someProxyPort");client.getState().setProxyCredentials(authScope, credentials);EntityEnclosingMethod method = new PostMethod(url);method.setRequestEntity(new StringRequestEntity(requestXML, "text/xml", "utf-8"));
