java后端-携带String参数请求URL

package io.sage.utils;import java.io.BufferedReader;import java.io.InputStreamReader;import java.io.PrintWriter;import java.net.URI;import java.net.URL;import java.net.URLConnection;/** * 携带参数请求(跨项目)url */public class PushMsg {
       public static String pushMsg(String allConfigUrl, String params) {
           BufferedReader in = null;        StringBuffer result = null;        try {
               //url请求中如果有中文，要在接收方用相应字符转码            URI uri = new URI(allConfigUrl);            URL url = uri.toURL();            URLConnection connection = url.openConnection();            connection.setRequestProperty("Content-type", "application/json; charset=utf-8");            connection.setRequestProperty("Accept-Charset", "utf-8");            connection.setRequestProperty("contentType", "utf-8");            connection.setDoOutput(true);            connection.setDoInput(true);            PrintWriter printWriter = new PrintWriter(connection.getOutputStream());            printWriter.print(params);            printWriter.flush();            connection.connect();            result = new StringBuffer();            //读取URL的响应            in = new BufferedReader(new InputStreamReader(connection.getInputStream(), "utf-8"));            String line;            while ((line = in.readLine()) != null) {
                   result.append(line);            }            return result.toString();        } catch (Exception e) {
               e.printStackTrace();        } finally {
               try {
                   if (in != null) {
                       in.close();                }            } catch (Exception e2) {
                   e2.printStackTrace();            }        }        return null;    }}

其中,参数String params可以使用JSONObject.toJSONString(Object)有序转化;
