[网络协议]gitee三方登录

gitee三方登录

步骤

1、先在gitee设置的第三方应用上创建应用，编写回调地址，和网址主页，生成Client ID 和 Client Secret

2、在点击用户授权之后，会在回调地址栏上出现一个code获取到code，请求 https://gitee.com/oauth/token 地址，post请求， ‘https://gitee.com/oauth/token?grant_type=authorization_code&’ . $code . ‘&client_id=’ . $client_id . ‘&redirect_uri=’ . $redirect_uri . ‘&client_secret=’ . $client_secret; 拼接url请求可以获得一个token。

3、通过token请求https://gitee.com/api/v5/user地址，get请求，https://gitee.com/api/v5/user?access_token=’ . $token，获得用户的基本信息$userinfo.

4、创建一个三方关联表，将用户信息和三方关联的信息存在表中，用来判断该三方账号是否已经绑定用户账号，没有则新增一个用户，返回用户信息，有的话就返回用户信息。

CREATE TABLE `trilateral_login` (
  `id` int unsigned NOT NULL AUTO_INCREMENT,
  `type` int DEFAULT NULL COMMENT '三方服务 1:gitee',
  `user_id` int DEFAULT NULL COMMENT '用户的id',
  `auth_id` varchar(255) CHARACTER SET utf8 COLLATE utf8_bin DEFAULT NULL COMMENT '验证的三方登录的唯一标识',
  `init_time` int DEFAULT NULL,
  `last_time` timestamp NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=utf8mb3 COLLATE=utf8_bin COMMENT='三方关联表';

配置文件config.php新增的配置

$config['gitee_get_token'] = 'https://gitee.com/oauth/token';
$config['gitee_get_info'] = 'https://gitee.com/api/v5/user';
$config['gitee_client_id'] = '70fe5fdf4ed079a2998a*********1e0af6a61bb80ae92b691e025eef2607***';
$config['gitee_client_secret'] = '7c02b14f9ea47f67*********fbd3f2b0a914b89f1f42ab76febdc12cf******';
$config['gitee_redirect_uri'] = 'http://ci.com/gitCallback';
