php – 如何使用google访问令牌获取用户电子邮件？

使用OAuth2,您可以通过scope参数请求权限. ( Documentation.)我想象你想要的范围是 https://www.googleapis.com/auth/userinfo.email和 https://www.googleapis.com/auth/userinfo.profile.

然后,获取访问令牌后,获取配置文件信息就很简单了. (我假设您已经能够兑换访问令牌的返回的授权码？)只需获得一个获取请求,到https://www.googleapis.com/oauth2/v1/userinfo?access_token= {accessToken},该访问返回一个JSON数组的配置文件数据,包括电子邮件：

{
    "id": "00000000000000","email": "fred.example@gmail.com","verified_email": true,"name": "Fred Example","given_name": "Fred","family_name": "Example","picture": "https://lh5.googleusercontent.com/-2Sv-4bBMLLA/AAAAAAAAAAI/AAAAAAAAABo/bEG4kI2mG0I/photo.jpg","gender": "male","locale": "en-US"
}

没有保证,但尝试这样：

$url = "https://www.googleapis.com/oauth2/v1/userinfo";
$request = apiClient::$io->makeRequest($client->sign(new apiHttpRequest($url,'GET')));

if ((int)$request->getResponseHttpCode() == 200) {
    $response = $request->getResponseBody();
    $decodedResponse = json_decode($response,true);
    //process user info
  } else {
    $response = $request->getResponseBody();
    $decodedResponse = json_decode($response,true);
    if ($decodedResponse != $response && $decodedResponse != null && $decodedResponse['error']) {
      $response = $decodedResponse['error'];
    }
  }
}
