推荐答案
您可能希望像某些应用程序一样使用您设备中已配置的 google 帐户之一对用户进行身份验证,请点击以下链接 -
You might want to authenticate the user using one of the google account already configured in your device like some of the apps do, for that follow the below link -
对 OAuth2 服务进行身份验证" - http://developer.android.com/training/id-auth/authenticate.html
"Authenticating to OAuth2 Services" - http://developer.android.com/training/id-auth/authenticate.html
从 Google 下载示例 - Android SDK Manager/Extras/Google Play Services
Download Sample from Google - Android SDK Manager/Extras/Google Play Services
只需简单的步骤
- 显示您手机中的帐户列表
- 从选定的帐户生成访问令牌
- 通过联系谷歌服务(单独调用)从访问令牌中获取帐户名称,以告知它已通过身份验证.
这是另一个可以很好地解释过程的链接 -http://android-developers.blogspot.in/2013/01/verifying-back-end-calls-from-android.html
This is another link which is good in explaining the process - http://android-developers.blogspot.in/2013/01/verifying-back-end-calls-from-android.html
您可以按照以下步骤在您的应用中登录
you can follow below steps for Login in your app
- 您将生成的访问令牌发送到您的后端服务器
- 后端服务器通过此 url "https://www.googleapis.com/oauth2/v1/userinfo?access_token=ACCESS_TOKEN"
- Next 后端服务器响应应用是否让用户登录.
下面是上面userinfo"调用的响应格式
Below is response format of above "userinfo" call
{
"id": "ID",
"name": "NAME",
"given_name": "GiVEN NAME",
"family_name": "FAMILY_NAME",
"link": "https://plus.google.com/ID",
"picture": "https://PHOTO.jpg",
"gender": "GENDER",
"locale": "LOCALE"
}
如果您想要电子邮件 ID 以及该回复,您必须修改
If you want Email id along with that response you have to modify
SCOPE = "oauth2:https://www.googleapis.com/auth/userinfo.profile";
SCOPE = "oauth2:https://www.googleapis.com/auth/userinfo.profile";
到
SCOPE = "oauth2:https://www.googleapis.com/auth/userinfo.profile https://www.googleapis.com/auth/userinfo.email";
SCOPE = "oauth2:https://www.googleapis.com/auth/userinfo.profile https://www.googleapis.com/auth/userinfo.email";
