当然，您可以使用 GET 或 POST

 public static String makeGETRequest(String s,String encoding)
{   
    DefaultHttpClient http = new DefaultHttpClient();
    HttpResponse res;
    try {

        res = http.execute(new HttpGet(s));
        InputStream is = res.getEntity().getContent();
        BufferedInputStream bis = new BufferedInputStream(is);
        ByteArrayBuffer baf = new ByteArrayBuffer(50);
        int current = 0;
        while((current = bis.read()) != -1){
              baf.append((byte)current);
         }

        return  new String(baf.toByteArray(),encoding);
       } 
    catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        return "error: " + e.getMessage();
    } 
    catch (IOException e) {
        // TODO Auto-generated catch block
        return "error: " + e.getMessage();
    } 

}

Post：

public static String makePOSTRequest(String s, List <NameValuePair> nvps,String encoding)
{

    DefaultHttpClient http = new DefaultHttpClient();


    HttpResponse res;
    try {
        HttpPost httpost = new HttpPost(s);
        httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.DEFAULT_CONTENT_CHARSET));

        res = http.execute(httpost);


        InputStream is = res.getEntity().getContent();
        BufferedInputStream bis = new BufferedInputStream(is);
        ByteArrayBuffer baf = new ByteArrayBuffer(50);
        int current = 0;
        while((current = bis.read()) != -1){
              baf.append((byte)current);
         }
        res = null;
        httpost = null;
        String ret = new String(baf.toByteArray(),encoding);
        return  ret;
       } 
    catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        return e.getMessage();
    } 
    catch (IOException e) {
        // TODO Auto-generated catch block
        return e.getMessage();
    } 

}
