###一个基于HttpURLConnection的轻量级HttpClient，请求实体均继承于RequestEntity，可拓展性强。 public class Test {
public static void main(String[] args) throws HttpException, IOException {
HttpClient httpClient = new HttpClient();
HttpRequest httpRequest = new HttpRequest(HttpMethod.POST,"http://localhost:8080/HttpClientTest/NewFile.jsp");
FormRequestEntity body = new FormRequestEntity();
body.addParam("name", "admin");
body.addParam("pass", "121212");
httpRequest.setRequestEntity(body);
HttpResponse response = httpClient.excute(httpRequest);
System.out.println(response.body());
}
}
