弹簧安全性，启用Oauth2时出现cors错误

Question

我在查询我的oauth / token端点时遇到错误。

我已经为我的资源配置了cors，并且还试图允许所有资源，但没有任何工作。

XMLHttpRequest无法加载http://localhost:8080/oauth/token。对预检请求的响应未通过访问控制检查：请求的资源上不存在“Access-Control-Allow-Origin”标头。因此，'http://localhost:1111'原产地不允许进入。响应具有HTTP状态代码401。

邮差一切都很完美。

我的cors安全配置：

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedOrigins("*")
                .allowedHeaders("*")
                .allowedMethods("*")
                .allowCredentials(true);
    }
}

还尝试在允许的起源中添加http://localhost:1111

邮递员代码：

require 'uri'
require 'net/http'

url = URI("http://localhost:8080/oauth/token")

http = Net::HTTP.new(url.host, url.port)

request = Net::HTTP::Post.new(url)
request["content-type"] = 'application/x-www-form-urlencoded'
request["authorization"] = 'Basic Y2hhdHRpbzpzZWNyZXRzZWNyZXQ='
request["cache-control"] = 'no-cache'
request["postman-token"] = 'daf213da-e231-a074-02dc-795a149a3bb2'
request.body = "grant_type=password&username=yevhen%40gmail.com&password=qwerty"

response = http.request(request)
puts response.read_body

Answer 1

经过很多努力，我已经超越了WebSecurityConfigurerAdapter类的方法配置（WebSecurity web），因为授权服务器自己配置了这个，而我还没有找到另一个解决方案。你还需要permit所有“/ oauth / token”Http.Options方法。我的方法：

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers(HttpMethod.OPTIONS, "/oauth/token");
}

在此之后，我们需要添加cors过滤器以将Http状态设置为OK。我们现在可以通过Http.Options方法来实现。

@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
@WebFilter("/*")
public class CorsFilter implements Filter {

    public CorsFilter() {
    }

    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        final HttpServletResponse response = (HttpServletResponse) res;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, PUT, GET, OPTIONS, DELETE");
        response.setHeader("Access-Control-Allow-Headers", "x-requested-with, authorization");
        response.setHeader("Access-Control-Max-Age", "3600");
        if ("OPTIONS".equalsIgnoreCase(((HttpServletRequest) req).getMethod())) {
            response.setStatus(HttpServletResponse.SC_OK);
        } else {
            chain.doFilter(req, res);
        }
    }

    @Override
    public void destroy() {
    }

    @Override
    public void init(FilterConfig config) throws ServletException {
    }
}

Answer 2

我找到了一种方法来修复Spring Security 5和Spring Security OAuth 2.3.5上的401错误，而不会关闭令牌端点上所有OPTIONS请求的安全性。我意识到您可以通过AuthorizationServerSecurityConfigurer向令牌端点添加安全过滤器。我尝试添加一个CorsFilter，它的工作原理。我用这种方法唯一的问题是我无法利用Spring MVC的CorsRegistry。如果有人能弄清楚如何使用CorsRegistry，请告诉我。

我已经为我的解决方案复制了一个示例配置：

import org.springframework.context.annotation.Configuration;
import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerSecurityConfigurer;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;

@Configuration
@EnableAuthorizationServer
public static class AuthServerConfiguration extends AuthorizationServerConfigurerAdapter {
    //... other config

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) {
        //... other config

        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration config = new CorsConfiguration();
        config.applyPermitDefaultValues();

        // Maybe there's a way to use config from AuthorizationServerEndpointsConfigurer endpoints?
        source.registerCorsConfiguration("/oauth/token", config);
        CorsFilter filter = new CorsFilter(source);
        security.addTokenEndpointAuthenticationFilter(filter);
    }
}
