推荐答案
可以使用HttpPost,有方法可以给Request添加Header.
You can use HttpPost, there are methods to add Header to the Request.
DefaultHttpClient httpclient = new DefaultHttpClient();
String url = "http://localhost";
HttpPost httpPost = new HttpPost(url);
httpPost.addHeader("header-name" , "header-value");
HttpResponse response = httpclient.execute(httpPost);
