Java实现HTTP GET 通过 Body 来发送数据

 1 public class HttpGetWithEntity extends HttpEntityEnclosingRequestBase {
 2     public final static String METHOD_NAME = "GET";

 4     public HttpGetWithEntity() {
 5         super();
 6     }

 8     public HttpGetWithEntity(final URI uri) {
 9         super();
10         setURI(uri);
11     }
12     
13     public HttpGetWithEntity(final String uri) {
14         super();
15         setURI(URI.create(uri));
16     }
17 
18     @Override
19     public String getMethod() {
20     // TODO Auto-generated method stub
21         return METHOD_NAME;
22     }
23 
24 }

public class test {
