@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
