基本概念

QQ群idkey：没有官方解释，在QQ群推广页面可以获得。

QQ群加群链接：即带有QQ群idkey的一个特殊URL。

问题描述

 QQ群推广官网：https://qun.qq.com/join.html

可以获得当前登入QQ号所管理的QQ群的 idkey ，但是不能自定义QQ群号并获取QQ群的 idkey。

问题分析 

 经分析获取QQ群的 idkey 的API如下所示：

GET请求：

参数如下所示：

注：QQ群列表以 ","（英文逗号）分割。 

必须的Request Headers如下所示： 

但查找资料过程中发现替换成

http://qun.qq.com/join.html

亦可。 

Request示例： 

Response示例：
