當前商城(uid標識)授權第三方開發平臺.

網頁授權成功后跳轉到另一個商城項目鏈接并帶上當前微信用戶信息和微信初始化驗證簽名.

創建一個跳轉到微信掃二維碼授權頁面

/**
 * 開發平臺授權跳轉
 *
 * @return void
 */
public function accessView(){
    // 
    $uid = Request()->route("uid" , 0);
    $url = "http://qgcloud.capsui.com/public/index/wxopen/config?uid=" . $uid;
    $this->assign("url" , $url);
    return $this->fetch();
}

跳轉方法(為什么我不寫到上一個方法呢 因為微信要求同一個地址)

/**
 * 開發平臺跳轉授權掃碼頁
 *
 * @return void
 */
public function config(){
    $uid = Request()->get("uid" , 0);
    $config = [
        "app_id"   => "開放平臺第三方平臺 APPID",
        "secret"   => "開放平臺第三方平臺 Secret",
        "token"    => "開放平臺第三方平臺 Token",
        "aes_key"  => "開放平臺第三方平臺 AES Key"
    ];
    $openPlatform = Factory::openPlatform($config);
    
    $url = $openPlatform->getPreAuthorizationUrl("http://qgcloud.capsui.com/public/index/wxopen/wxcallback?uid=" . $uid);

    $this->redirect($url);
}

授權回調(注意:掃碼確認授權后他第一次回調不會帶uid參數,)
