Spring Security OAuth

Casdoor可以使用OIDC协议作为IDP连接各种应用程序。在本指南中，我们将以Spring Security为例，向您展示如何使用OIDC连接到您的应用程序。

步骤1：部署Casdoor

Deploy Casdoor. See Server installation. Ensure the server is running and you can open the login page and sign in (e.g. admin / 123).

步骤2。配置Casdoor应用程序

创建一个新的Casdoor应用程序或使用现有的一个。
添加您的重定向URL（您可以在下一节中找到如何获取重定向URL的更多详细信息）。 ```
添加所需的提供者并填写任何其他设置。

Note Client ID and Client secret from the application page for the next step. OIDC discovery: http://<CASDOOR_HOSTNAME>/.well-known/openid-configuration.

步骤3。配置Spring Security

Spring Security原生支持OIDC。

您可以自定义Spring Security OAuth2 客户端的设置：

注意事项

Replace the placeholders with your own Casdoor instance (Client ID, Client secret, etc.).

application.yml
application.properties

spring:
  security:
    oauth2:
      client:
        registration:
          casdoor:
            client-id: <Client ID>
            client-secret: <Client Secret>
            scope: <Scope>
            authorization-grant-type: authorization_code
            redirect-uri: <Redirect URL>
        provider:
          casdoor:
            authorization-uri: http://CASDOOR_HOSTNAME:7001/login/oauth/authorize
            token-uri: http://CASDOOR_HOSTNAME:8000/api/login/oauth/access_token
            user-info-uri: http://CASDOOR_HOSTNAME:8000/api/get-account
            user-name-attribute: name

spring.security.oauth2.client.registration.casdoor.client-id=<Client ID>
spring.security.oauth2.client.registration.casdoor.client-secret=<Client Secret>
spring.security.oauth2.client.registration.casdoor.scope=<Scope>
spring.security.oauth2.client.registration.casdoor.authorization-grant-type=authorization_code
spring.security.oauth2.client.registration.casdoor.redirect-uri=<Redirect URL>

spring.security.oauth2.client.provider.casdoor.authorization-uri=http://CASDOOR_HOSTNAME:7001/login/oauth/authorize
spring.security.oauth2.client.provider.casdoor.token-uri=http://CASDOOR_HOSTNAME:8000/api/login/oauth/access_token
spring.security.oauth2.client.provider.casdoor.user-info-uri=http://CASDOOR_HOSTNAME:8000/api/get-account
spring.security.oauth2.client.provider.casdoor.user-name-attribute=name

注意事项

对于Spring Security的默认情况，<Redirect URL>应该像http://<Your Spring Boot Application Endpoint>/<Servlet Prefix if it is configured>/login/oauth2/code/custom这样。例如，对于下面的演示来说，重定向URL应该是 http://localhost:8080/login/oauth2/code/code/custom。您也应该在casdoor应用程序中配置这个。

您还可以在代码中使用ClientRegistration来自定义设置。您可以在这里找到映射

步骤4：开始使用演示

我们可以创建 Spring Boot 应用程序。

我们可以添加一个配置，保护所有端点，除了/和/login**供用户登录。

@EnableWebSecurity
public class UiSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .antMatchers("/", "/login**")
            .permitAll()
            .anyRequest()
            .authenticated()
            .and()
            .oauth2Login();

    }
}

我们可以为用户添加一个简单的登录页面。

<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Spring OAuth Client Thymeleaf - 1</title>
<link rel="stylesheet"
    href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" />
</head>
<body>
    <nav
        class="navbar navbar-expand-lg navbar-light bg-light shadow-sm p-3 mb-5">
        <a class="navbar-brand" th:href="@{/foos/}">Spring OAuth Client
            Thymeleaf - 1</a>
    </nav>
    <div class="container">
        <label>Welcome!</label> <br /> <a th:href="@{/foos/}"
            class="btn btn-primary">Login</a>
    </div>
</body>
</html>

当用户点击login按钮时，他们将被重定向到casdoor。

接下来，我们可以定义我们的受保护资源。我们可以公开一个名为/foos的端点和一个用于显示的网页。

数据模型

public class FooModel {
    private Long id;
    private String name;

    public FooModel(Long id, String name) {
        super();
        this.id = id;
        this.name = name;
    }
    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

控制器

@Controller
public class FooClientController {
    @GetMapping("/foos")
    public String getFoos(Model model) {
        List<FooModel> foos = new ArrayList<>();
        foos.add(new FooModel(1L, "a"));
        foos.add(new FooModel(2L, "b"));
        foos.add(new FooModel(3L, "c"));
        model.addAttribute("foos", foos);
        return "foos";
    }
}
