具体使用，参考我的代码

     * @throws GuzzleException
     */
    public function handleMpCallback(User $UserRepository, MiniProgram $miniProgram, $name)
    {
        $key  = $miniProgram->getSessionKey($name);
        $data = $miniProgram->getDecryptData($key);
        if ($data) {
            $snsInfo = $miniProgram->snsUserInfo($data);
            $user    = $UserRepository->fromSns($snsInfo);
            $visible = [ 'id', 'nick', 'avatar', 'api_token' ];
            return prettyJson([ 'code' => 200, 'data' => $user->setVisible($visible)->toArray() ]);
        } else {
            return response()->json([ 'error' => 'Can not decrypt data' ], 500);
        }
    }
