二、HttpAsyncClient

@Override public Map<String, Object> updateStoreProduct(String product) {  List<Param> param = Arrays.asList(new Param("product", product));  return this.post("storeproductapi.do", "updateStoreProduct", param); }Map<String, Object> post(String url, String method, List<Param> param) {  List<Param> params = param;  if (params == null) {   params = new ArrayList<>();  } else {   params = new ArrayList<>(param);  }  params.add(new Param("method", method));  params.add(new Param("charset", "gbk"));  //设置请求的来源，W:触屏版，A：android App，I：ios App  params.add(new Param("source", "W"));  logger.debug("param:" + JsonUtil.writeValue(params));  try {   Map<String, Object> ret = HttpClientUtil.post(this.base + "api/"     + url, params, "gbk");   logger.debug("ret:" + JsonUtil.writeValue(ret));   return ret;  } catch (Exception e) {   e.printStackTrace();  }  return null; }/**  * @param url  * @param params  * @param charset  * @return  * @throws IOException   * @throws ExecutionException Http  * @throws InterruptedException   */ public static Map<String,Object> post(String url,List<Param> params,String charset) throws IOException, InterruptedException, ExecutionException{  CloseableHttpAsyncClient httpclient = HttpAsyncClients.createDefault();  try{   httpclient.start();   HttpPost post=new HttpPost(url);   List<NameValuePair> form=new ArrayList<>();   for(Param p:params){    form.add(new BasicNameValuePair(p.getName(), p.getValue()));   }   post.setEntity(new UrlEncodedFormEntity(form, charset));   HttpResponse resp=httpclient.execute(post, null).get();   return JsonUtil.readValue(IOUtils.toString(resp.getEntity().getContent(), charset),Map.class);  }finally{   httpclient.close();  }   }

三、UrlConnection

四、volley

五、okhttp、retrofit

后两种是android通用通信框架
