java - spring-security oauth2 REST 服务器在错误凭据(400)错误响应中不需要的 Stacktrace

Question

我们有一个基于 Oauth2 的 REST 服务器(资源 + 授权)，由 spring-security + spring web + jersey 提供，用于我们的 REST 资源。大多数情况都很好，但是当使用错误凭据在用户名-密码流中点击/oauth/token 时，我们不仅得到 400(按照规范是正确的)，而且响应中的整个堆栈跟踪为 JSON .我已经搜索、调试和摸索，但无法完全找到罪魁祸首。这可能是 Spring 安全设置吗？还是 Spring 网？还是使用 jersey 映射资源的 servlet？

示例响应(缩写):

有什么想法吗？如果您需要更多信息，请告诉我 (web.xml/security.xml/application.xml/servlet.xml)

谢谢!

编辑:使用带有错误凭据的客户端凭据流，它会给我一个 401 并且没有堆栈跟踪。只是当用户名/密码不匹配时抛出的 BadCredentials/InvalidGrant 异常会导致堆栈跟踪。

servlet-context.xml 只包含 freemarker 的东西，应该无关紧要jersey-servlet 也不重要，因为它只映射/rest/** 资源并且请求的资源是/oauth/token。只剩下 Spring 安全设置:

嗯，对我来说，这里似乎没有明显的配置位置。

堆栈跟踪表明，ResourceOwnerPasswordTokenGranter 引发了未处理的 InvalidGrantException。因此，我尝试在 web.xml 中的 spring-security 过滤器上方的过滤器链中添加过滤器，捕获所有异常并处理它们。但是不起作用，因为 spring-security 过滤器似乎自己处理 InvalidGrantException，这意味着没有异常会冒泡到我周围的过滤器。

TokenEndpoint (@RequestMapping(value = "/oauth/token")) 调用 ResourceOwnerPasswordTokenGranter 来验证用户名/密码:

@FrameworkEndpoint
@RequestMapping(value = "/oauth/token")
public class TokenEndpoint extends AbstractEndpoint {
    @RequestMapping
    public ResponseEntity<OAuth2AccessToken> getAccessToken(Principal principal,
            @RequestParam("grant_type") String grantType, @RequestParam Map<String, String> parameters) {
        // ...
        // undhandled:
        OAuth2AccessToken token = getTokenGranter().grant(grantType, authorizationRequest);
        // ...
        return getResponse(token);
    }

引发了正确的异常:

public class ResourceOwnerPasswordTokenGranter extends AbstractTokenGranter {   

    @Override
    protected OAuth2Authentication getOAuth2Authentication(AuthorizationRequest clientToken) {
        // ...
        try {
            userAuth = authenticationManager.authenticate(userAuth);
        }
        catch (BadCredentialsException e) {
            // If the username/password are wrong the spec says we should send 400/bad grant
            throw new InvalidGrantException(e.getMessage());
        }
    }

}

但即使在端点回击时也从未处理过。然后过滤器链进行异常处理并添加堆栈跟踪。相反，端点应该返回一个没有堆栈跟踪的干净 400，即处理该死的异常!

现在我能看到的唯一方法是覆盖 TokenEndpoint 并捕获异常。

有更好的想法吗？

Answer 1

您可以为该特定异常编写一个 ExceptionMapper 并对请求做任何您想做的事情。每当您的端点方法抛出定义的异常时，ExceptionMapper 都会处理响应。

import javax.ws.rs.core.Response;
import javax.ws.rs.ext.ExceptionMapper;
import javax.ws.rs.ext.Provider;

@Provider
public class MyExceptionMapper implements ExceptionMapper<InvalidGrantException>
{
    @Override
    public Response toResponse(InvalidGrantException exception)
    {
        return Response.status(Response.Status.BAD_REQUEST).build(); 
    }
}

我猜你总是可以覆盖 EntryPoint 类(如 this StackOverflow Question 所示)。

定制的 OAuth2ExceptionRenderer(参见 SO: Customize SpringSecurity OAuth2 Error Output 也可以。
