添加 templates

  • confirm.html
  • login.html

创建启动类启动项目

@SpringBootApplication
public class MingYueAuthApplication {

	public static void main(String[] args) {
		SpringApplication.run(MingYueAuthApplication.class, args);
		System.out.println("\nSa-Token-OAuth  Server端启动成功: http://localhost:9000/oauth2/authorize?response_type=code&client_id=1001&redirect_uri=https://sa-token.cc&scope=userinfo");
	}

}

启动项目,访问打印地址:

Sa-Token-OAuth Server端启动成功: http://localhost:9000/oauth2/authorize?response_type=code&client_id=1001&redirect_uri=https://sa-token.cc&scope=userinfo

API 列表

共四种模式,分别是授权码(Authorization Code)、隐藏式(Implicit)、密码式(Password)、凭证式(Client Credentials),本文介绍了两种常用的:授权码(Authorization Code)、密码式(Password)

1. 授权码(Authorization Code)

http://localhost:9000/oauth2/authorize
?response_type=code
&client_id=1001
&redirect_uri=https://sa-token.cc&scope=userinfo

参数详解:

参数 是否必填 说明
response_type 返回类型,这里请填写:code
client_id 应用id
redirect_uri 用户确认授权后,重定向的url地址
scope 具体请求的权限,多个用逗号隔开
state 随机值,此参数会在重定向时追加到url末尾,不填不追加

1.1 获取授权码

Code授权码具有以下特点:

  1. 每次授权产生的 Code 码都不一样
  2. Code码用完即废,不能二次使用
  3. 一个Code的有效期默认为五分钟,超时自动作废
  4. 每次授权产生新 Code 码,会导致旧 Code 码立即作废,即使旧 Code 码尚未使用

http://localhost:9000/oauth2/authorize?response_type=code&client_id=1001&redirect_uri=https://sa-token.cc&scope=userinfo

打开地址,登录并同意授权

地址栏拿到 code https://sa-token.cc/?code=ct0RB10UkGSwXINdBkGRGVKBvoKjIi6jzeYi3NFrCwoXzDr36Ljgm1ZBplYx

1.2 根据授权码获取 Access-Token

浏览器直接访问:

http://localhost:9000/oauth2/token
    ?grant_type=authorization_code
    &client_id=1001
    &client_secret=aaaa-bbbb-cccc-dddd-eeee
    &code=ktN6FvIfB7pKqp7Thvkm32EfUhbveoybwOtmvqCCbuLdxevmyr9FW09Kd6qL
参数 是否必填 说明
grant_type 授权类型,这里请填写:authorization_code
client_id 应用id
client_secret 应用秘钥
code 步骤1.1中获取到的授权码

打印如下:

{
    "code": 200,
    "msg": "ok",
    "data": {
        "access_token": "E1ZLgNXLiUIz8DmAxmgPeegMPsUCEJJLjUV9uwDQWCu4f6Tgg8U5JqKSrqSx",
        "refresh_token": "0IAWolcbMvoIpF8F1JcEuytfcoTe8nNVwsEdUHOy7rBX0V99vhPBvtFGfh62",
        "expires_in": 7199,
        "refresh_expires_in": 2591999,
        "client_id": "1001",
        "scope": "userinfo",
        "openid": "gr_SwoIN0MC1ewxHX_vfCW3BothWDZMMtx__"
    }
}

2. 密码式(Password)

首先在 Client 端构建表单,让用户输入 Server 端的账号和密码,然后在 Client 端访问接口

http://localhost:9000/oauth2/token
    ?grant_type=password
    &client_id=1001
    &client_secret=aaaa-bbbb-cccc-dddd-eeee
    &username=sa
    &password=123456
参数 是否必填 说明
grant_type 返回类型,这里请填写:password
client_id 应用id
client_secret 应用秘钥
username 用户的Server端账号
password 用户的Server端密码
scope 具体请求的权限,多个用逗号隔开

浏览器直接访问,打印如下:

{
    "code": 200,
    "msg": "ok",
    "data": {
        "access_token": "BvU1yja6sy4WT3orCvIiYExIOhGMBwVps38ZywZWGaeYaM6nJbPkJRbHpmSC",
        "refresh_token": "TzSGmGhtPuAZUZ5ndfVETdmmpGr3ZwAH5N5kbrEYeeR2LKbLBXEysqsLxuV6",
        "expires_in": 7199,
        "refresh_expires_in": 2591999,
        "client_id": "1001",
        "scope": "",
        "openid": "gr_SwoIN0MC1ewxHX_vfCW3BothWDZMMtx__"
    }
}

至此,一个基于 OAuth2 的认证中心 Demo 就完成啦,接下来我们先优化一下代码结构。
