无法使 EnableOauth2Sso 工作 - BadCredentialsException：无法获取访问令牌答案

【问题标题】：Unable to get EnableOauth2Sso Working -- BadCredentialsException: Could not obtain access token无法使 EnableOauth2Sso 工作 - BadCredentialsException：无法获取访问令牌
【发布时间】：2015-10-01 17:25:29
【问题描述】：

我正在尝试让一个简单的 Spring OAuth2 SSO 应用程序正常工作，但我一直无法这样做。以下是所发生事情的步骤和结果：

点击端点/user，由OAuth2保护
我被转发到一个简单的 Spring OAuth2 授权服务器
我向授权服务器进行身份验证
我批准了访问

然后我在 OAuth2 SSO 应用程序上收到一个白标错误页面，其中包含以下内容：

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

Mon Jul 13 08:19:18 EDT 2015
There was an unexpected error (type=Unauthorized, status=401).
Authentication Failed: Could not obtain access token

授权码在 URL 中。下面是示例网址：

http://localhost:8083/login?code=9s63rU&state=Fo9S2M

我没有看到授权服务器 /oauth/token 端点的 HTTP POST 来获取 JWT。我通过授权服务器上的/trace 端点验证了这一点。

异常堆栈为：

:: 更新 1 ::

我开始调试它并发现实际抛出的异常是InvalidRequestException，并带有一条消息：Possible CSRF detected - state parameter was present but no state could be found on line 244 of AuthorizationCodeAccessTokenProvider。

我尝试将我的 Oauth2SsoConfigurerAdapter 修改为此，但我仍然遇到相同的异常：

@Configuration
protected static class SecurityConfiguration extends OAuth2SsoConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.logout().and().antMatcher("/**").authorizeRequests()
                .antMatchers("/index.html", "/home.html", "/", "/login").permitAll()
                .anyRequest().authenticated().and().csrf()
                .csrfTokenRepository(csrfTokenRepository()).and()
                .addFilterAfter(csrfHeaderFilter(), CsrfFilter.class);
    }

    private Filter csrfHeaderFilter() {
        return new OncePerRequestFilter() {
            @Override
            protected void doFilterInternal(HttpServletRequest request,
                                            HttpServletResponse response, FilterChain filterChain)
                    throws ServletException, IOException {
                CsrfToken csrf = (CsrfToken) request.getAttribute(CsrfToken.class
                        .getName());
                if (csrf != null) {
                    Cookie cookie = WebUtils.getCookie(request, "XSRF-TOKEN");
                    String token = csrf.getToken();
                    if (cookie == null || token != null
                            && !token.equals(cookie.getValue())) {
                        cookie = new Cookie("XSRF-TOKEN", token);
                        cookie.setPath("/");
                        response.addCookie(cookie);
                    }
                }
                filterChain.doFilter(request, response);
            }
        };
    }

    private CsrfTokenRepository csrfTokenRepository() {
        HttpSessionCsrfTokenRepository repository = new HttpSessionCsrfTokenRepository();
        repository.setHeaderName("X-XSRF-TOKEN");
        return repository;
    }
}

:: 更新 2 ::

InvalidRequestException 被抛出，因为来自DefaultAccessTokenRequest 的preservedState 正在返回null（请参阅AuthorizationCodeAccessTokenProvider 的line 239）。

preservedState 设置在Oauth2RestTemplate 中的DefaultAccessTokenRequest line 212 上，我确定DefaultOauth2ClientContext 映射为空并返回null。

接下来我将尝试在DefaultOAuth2ClientContext 中验证setPreserveState 调用。

:: 更新 3 ::

我更新了我的客户端配置以使用 Github 而不是我自己的 Spring OAuth2 授权服务器，它可以工作。对我来说，这表明我的授权服务器配置可能存在问题。

我将尝试在我的 OAuth 服务器上进行一些调试，看看我是否能找出问题所在。

:: 更新 4 ::

成功！我在同一主机上运行 OAuth2 授权和客户端服务器，但端口不同。当我将客户端的上下文路径设置为根以外的其他内容时，一切都开始工作了。

我怀疑这与 JSESSIONID 和 cookie 有关。谁能将我链接到文档以解释其工作原理以供将来参考？

谢谢！

【问题讨论】：

哇！由于您的研究，我遇到了完全相同的问题并且可以解决它！非常感谢你的坚持！ :)
谢谢！请提供它作为接受的答案。
请提供您在更新 4 中写的内容作为答案。您的问题仍然显示为未回答。
谢谢！为您解答。

【解决方案1】：

Centinul 你已经发现这是由于 cookie 冲突而发生的，不幸的是 cookie 不尊重端口号。所以这两个应用程序相互干扰，因为两者都设置JSESSIONID。

有两种简单的解决方法：

使用server.context-path 将每个应用程序移动到不同的路径，请注意，您需要为两者都这样做
将一个应用程序的server.session.cookie.name 设置为不同的值，例如APPSESSIONID

我建议将此解决方法放在您仅为 localhost 激活的配置文件中。

【讨论】：

【解决方案2】：

创建客户端应用程序：如果您在 localhost 上同时运行客户端和身份验证服务器，则上下文路径必须明确，否则 cookie 路径会发生冲突，并且两个应用程序无法就会话标识符达成一致。

但是在教程中你链接是错误的。使用 server.servlet.context-path 属性
