[英]Laravel Socialite token refreshing
Socialite(通过Socialite::driver(self::PROVIDER)->user()
获取的access_token
是有时间限制的,Google是一个小时。
我可以通过将重定向调用更改为以下方式来获取refresh_token
:
Socialite::driver(self::PROVIDER)->stateless()->with([
'access_type' => 'offline',
])->redirect()
一个小时后,我可以通过调用来读取基于access_token
的用户数据
// $token = read_stored_access_token()
\Socialite::driver(self::PROVIDER)->userFromToken($accessToken);
一个小时后,当令牌无效时,Google API 开始返回401 Unauthorized
并且 Socialite 将其传播出去:
(1/1) ClientException
Client error: `GET https://www.googleapis.com/plus/v1/people/me?prettyPrint=false` resulted in a `401 Unauthorized` response:
{"error":{"errors":[{"domain":"global","reason":"authError","message":"Invalid Credentials","locationType":"header","loc (truncated...)
现在有了refresh_token
,我应该能够轻松地刷新access_token
。 但是我在 Socialite 文档或源代码中找不到允许我这样做的提及。
真的是使用 Google 的 API 库并手动执行此操作的唯一方法吗? 它不会扼杀使用 Socialite 的整个想法吗?
注意:我试图避免再次调用redirect()
,因为它可能会迫使用户每小时选择一个他的 Google 帐户,这很烦人。
谢谢!
这是我通过离线访问从 Socialite 中保存用户的方式:
$newUser = new User;
$newUser->name = $user->name;
$newUser->email = $user->email;
$newUser->google_id = $user->id;
$newUser->google_token = $user->token;
$newUser->token_expires_at = Carbon::now()->addSeconds($user->expiresIn);
$newUser->google_refresh_token = $user->refreshToken;
$newUser->avatar = $user->avatar;
$newUser->avatar_original = $user->avatar_original;
$newUser->save();
这是我的令牌刷新解决方案。 我通过在我的用户模型中为令牌属性创建访问器来实现它:
/**
* Accessor for google token of the user
* Need for token refreshing when it has expired
*
* @param $token
*
* @return string
*/
public function getGoogleTokenAttribute( $token ) {
//Checking if the token has expired
if (Carbon::now()->gt(Carbon::parse($this->token_expires_at))) {
$url = "https://www.googleapis.com/oauth2/v4/token";
$data = [
"client_id" => config('services.google.client_id'),
"client_secret" => config('services.google.client_secret'),
"refresh_token" => $this->google_refresh_token,
"grant_type" => 'refresh_token'
];
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/x-www-form-urlencoded']);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$result = curl_exec($ch);
$err = curl_error($ch);
curl_close($ch);
if ($err) {
return $token;
}
$result = json_decode($result, true);
$this->google_token = isset($result['access_token']) ? $result['access_token'] : "need_to_refresh";
$this->token_expires_at = isset($result['expires_in']) ? Carbon::now()->addSeconds($result['expires_in']) : Carbon::now();
$this->save();
return $this->google_token;
}
return $token;
}
return Socialite::driver('google')
->scopes()
->with(["access_type" => "offline", "prompt" => "consent select_account"])
->redirect();
默认情况下,refresh_token 仅在第一次授权时返回,通过添加“prompt”=>“consent select_account”,我们强制每次都返回它。
