获取GOOGLE永久token

第一步：获取code

    public function googleToken()
    {
  
        if (Input::has('code') && ($code = Input::get('code', 'str', ''))) {
            var_dump($_REQUEST);
            die;
        } else {
            $this->redirect("https://accounts.google.com/o/oauth2/auth?scope=https://www.googleapis.com/auth/androidpublisher&response_type=code&access_type=offline&redirect_uri=您的域名接口/googleToken&client_id=". Config::get('google.clientid'));
        }
    } 

第二步：获取永久token[字段名：refresh_token]

请求地址： https://accounts.google.com/o/oauth2/token
请求方式：POST

结果：

{
    "access_token": "ya29.a0ARrdaM_KAdN0Eojm8LMIr2WyVEorQv3iOdHbgtSqPhEFN8m9JiEcuwf4UFIKKAKtT-ocRsY8Q9uGBe8t2G6ys9zt0x9KchV2VFmOY_zxJQ6g7xhhh3alBoZvW-JYV3acI6T_O5Xd-JZXWmk2xMocj1jXxymU",
    "expires_in": 3599,
    "refresh_token": "1//0Y_mLA",  //這個參數只會返回一次，記得存起來，GOOGLE後臺可以設置有效期的
    "scope": "https://www.googleapis.com/auth/androidpublisher",
    "token_type": "Bearer"
}
