Java-apache http客户端用法示例，显示cookie的使用以及从HTTPResponse对象提取响应

1）AS为cookie，请参见示例：

httpcomponents-client-4.1.3 examples org apache http examples
client ClientCustomContext.java

主要代码：

HttpClient httpclient = new DefaultHttpClient();        try { // Create a local instance of cookie store cookieStore cookieStore = new BasiccookieStore(); // Create local HTTP context HttpContext localContext = new BasicHttpContext(); // Bind custom cookie store to the local context localContext.setAttribute(ClientContext.cookie_STORE, cookieStore); HttpGet httpget = new HttpGet("http://www.google.com/"); System.out.println("executing request " + httpget.getURI()); // Pass local context as a parameter HttpResponse response = httpclient.execute(httpget, localContext);        } finally { // When HttpClient instance is no longer needed, // shut down the connection manager to ensure // immediate deallocation of all system resources httpclient.getConnectionManager().shutdown();        }

2）您可以从响应中获得所需的一切，并且：

HttpEntity entity = response.getEntity();entity.getContent()
