java - 没有 client_secret 的 Spring Security OAuth 2.0

Question

我正在使用 Spring Boot 和 Spring Security OAuth 2.0 为我的 Android 应用程序开发登录系统。

我的起点是以下演示存储库:https://github.com/royclarkson/spring-rest-service-oauth。在演示中，您可以找到以下设置:

OAuth2 客户端:

clients
    .inMemory()
        .withClient("clientapp")
            .authorizedGrantTypes("password", "refresh_token")
            .authorities("USER")
            .scopes("read", "write")
            .resourceIds(RESOURCE_ID)
            .secret("123456");

在其测试中获取访问 token 的方法:

private String getAccessToken(String username, String password) throws Exception {
    String authorization = "Basic " + new String(Base64Utils.encode("clientapp:123456".getBytes()));

    String content = mvc
        .perform(
                post("/oauth/token")
                        .header("Authorization", authorization)
                        .contentType(MediaType.APPLICATION_FORM_URLENCODED)
                        .param("username", username)
                        .param("password", password)
                        .param("grant_type", "password")
                        .param("scope", "read write")
                        .param("client_id", "clientapp")
                        .param("client_secret", "123456"))
        .andExpect(status().isOk())
        .andReturn().getResponse().getContentAsString();

    return content.substring(17, 53);
}

项目中的每个测试都提供完美的工作，但我想以不同的方式做事，但我在这样做时遇到了麻烦。如您所见，演示客户端定义了一个 client_secret(也在测试中使用)但是 client_secret 在 Android 环境中真的毫无值(value)，我不能保证它的 '隐私”。

参见 https://apigility.org/documentation/auth/authentication-oauth2:

If we are using a public client (by default, this is true when no secret is associated with the client) you can omit the client_secret value;

并查看 https://datatracker.ietf.org/doc/html/draft-ietf-oauth-v2-31#section-2.1 :

Public:Clients incapable of maintaining the confidentiality of theircredentials (e.g. clients executing on the device used by theresource owner such as an installed native application or a webbrowser-based application), and incapable of secure clientauthentication via any other means.

所以我所做的就是删除客户端配置中的 secret :

clients
    .inMemory()
        .withClient("books_password_client")
        .authorizedGrantTypes("password", "refresh_token")
        .authorities("USER")
        .scopes("read", "write")
        .resourceIds(RESOURCE_ID);

还修改了getAccessToken(...)方法:

private String getAccessToken(String username, String password) throws Exception {
    String authorization = "Basic " + new String(Base64Utils.encode("books_password_client:123456".getBytes()));

    String content = mvc
        .perform(
                post("/oauth/token")
                        .contentType(MediaType.APPLICATION_FORM_URLENCODED)
                        .param("username", username)
                        .param("password", password)
                        .param("grant_type", "password")
                        .param("client_id", "books_password_client"))
        .andExpect(status().isOk())
        .andReturn().getResponse().getContentAsString();

    return content.substring(17, 53);}
}

但是当我使用这个新设置时，我的测试失败了，我无法获得访问 token ，我不断收到 HTTP 错误 401 Unauthorized。

这就是我的工作:

Response response =
    given().
        auth()
            .preemptive().basic("clientapp", "")
            .formParam("username", username)
            .formParam("password", password)
            .formParam("grant_type", "password")
            .formParam("scope", "read%20write")
    when()
        .post("/oauth/token").
    then()
        .extract().response();
