网上的源码大都失效 经 @Timi.杨 提醒吾爱一位老哥的源码 2018最新根据群号得到idkey以及加群链接 还可以用

所以简单修改了一下改成了API接口

使用示例

• API服务：https://tenapi.cn/v2/group?qun=679849986&format=json
• 文档地址：https://docs.tenapi.cn/tencent/group.html

返回数据

{
  "code": 200,
  "data": {
    "gid": 679849986,
    "idkey": "a5cef71d9834cdf84e87850ead503d4bf91a7405e6ac6518bcc0e622bfb85669",
    "url": "http://wp.qq.com/wpa/qunwpa?idkey=a5cef71d9834cdf84e87850ead503d4bf91a7405e6ac6518bcc0e622bfb85669"
  }
}

PHP源码

<?php
$qqun = $_GET['qun'];
$type = $_GET['type'];
$t = time() * 1000;
if ($qqun == '') {
    echo "参数不能为空";
}
if ($qqun != null) {
    $url = "http://wp.qq.com/wpa/g_wpa_get?guin=" . $qqun . "&t=" . $t;
    $arr = json_decode($url, true);
    $ResArray = json_decode(file_get_content($url, 'get'), true);
    $uid = $ResArray['result']['data'][0]['guin'];
    $idkey = $ResArray['result']['data'][0]['key'];
    if ($type == 301) {
        $cs = 'http://wp.qq.com/wpa/qunwpa?idkey=' . $idkey . '';
        header("Location:{$cs}");
    }
    $Json = array("code" => 200, "data" => array("uid" => $uid, "idkey" => $idkey, "url" => 'http://wp.qq.com/wpa/qunwpa?idkey=' . $idkey . ''));
    $Json = json_encode($Json, JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE);
    echo stripslashes($Json);
    return $Json;
}
