HttpClient介绍

[英]Interface for an HTTP client. HTTP clients encapsulate a smorgasbord of objects required to execute HTTP requests while handling cookies, authentication, connection management, and other features. Thread safety of HTTP clients depends on the implementation and configuration of the specific client.
[中]HTTP客户端的接口。HTTP客户端封装了执行HTTP请求所需的大量对象，同时处理cookie、身份验证、连接管理和其他功能。HTTP客户端的线程安全取决于特定客户端的实现和配置。

代码示例

HttpClient httpclient = new DefaultHttpClient(); // Create HTTP Client
HttpGet httpget = new HttpGet("http://yoururl.com"); // Set the action you want to do
HttpResponse response = httpclient.execute(httpget); // Executeit
HttpEntity entity = response.getEntity(); 
InputStream is = entity.getContent(); // Create an InputStream with the response
BufferedReader reader = new BufferedReader(new InputStreamReader(is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) // Read line by line
  sb.append(line + "\n");

String resString = sb.toString(); // Result is here

is.close(); // Close the stream
