浅谈Java代码的 微信长链转短链接口使用 post 请求封装Json(实例)

废话不多说，直接上代码

string longurl = "https://open.weixin.qq.com/connect/oauth2/authorize?appid=" + mputil.appid + "&redirect_uri=" + mputil.homepage + "/nweixinloginpc.fo%3frandomcode=" + randomcode + "&response_type=code&scope=snsapi_userinfo&state=account#wechat_redirect";//什么不重要 ，自己的长链
        
        string accesstoken = mputil.getaccesstoken(mputil.appid, mputil.appsecret);        
        string shorturl = null;//短连接地址，生成二维码用，识别快
        string httpurl = "https://api.weixin.qq.com/cgi-bin/shorturl?access_token="+accesstoken; //此处访问微信短链方法
        
        /**
         * 调用举例
            curl -d "{\"action\":\"long2short\",
            \"long_url\":\"http://wap.koudaitong.com/v2/showcase/goods?alias=128wi9shh&spm=h56083&redirect_count=1\"}"
            "https://api.weixin.qq.com/cgi-bin/shorturl?access_token=access_token"
         */
        jsonobject jsonobject = new jsonobject();
        
        jsonobject.put("action", "long2short");
        jsonobject.put("long_url", longurl);
  
        string transjson = jsonobject.tostring()+httpurl;
        requestentity se = new stringrequestentity(transjson, "application/json", "utf-8");
        //微信返回的字符串
        //成功 {"errcode":0,"errmsg":"ok","short_url":"http:\/\/w.url.cn\/s\/avco6ih"}
        //失败 {"errcode":40013,"errmsg":"invalid appid"}
        string resultsstring = post(jsonobject,httpurl); //封装的post方法
　　　　　　　　　　
       string shorturl = mputil.getjsonvalue(resultsstring, "short_url");//得到的短链
