# 问题

项目技术架构： 前端：vue 后端：springcloud h版 1、网关：gateway （ 1）作为所有资源的统一访问入口，需要支持跨域 （2）依赖oauth2，使用resource相关api，同时作为资源服务器，进行权限认证

当写好接口后，本机使用postman测试，接口都正常返回，但配合前端测试时，一直出现下面两个问题，而前端使用proxy代理，也仍然无法解决。

# springcloud gateway + oauth2引起的跨域问题
# 问题一
Access to XMLHttpRequest at 'http://ip:port/userInfo' from origin 'http://localhost:8081' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

不论是自己写跨域过滤器，还是调整yml的配置，都得不到解决。

1、百度后，有人说要关掉weblfux的跨域，但不知道如何关。 2、后来发现，浏览器在发起options 探测请求时，一直被网关阻止，出现了401错误，怀疑可能是oauth2引起的。结合1中的提法，尝试引入oauth2的跨域配置，引入自定义跨域过滤器，问题得到解决。

解决办法：关掉ResourceServerConfig的跨域配置，并且引入自定义的跨域过滤器

SecurityWebFilterChain配置

 @Bean
    public SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
        // 关掉跨域
        http.cors().and().csrf().disable();
      // 增加自定义拦截器
        http.addFilterAt(new CorsFilter(), SecurityWebFiltersOrder.SECURITY_CONTEXT_SERVER_WEB_EXCHANGE);
        http.oauth2ResourceServer().jwt()
                .jwtAuthenticationConverter(jwtAuthenticationConverter());
        // 如果是token过期了，需要加到oauth2ResourceServer上，才会起作用，下面不知道为什么不起作用
        http.oauth2ResourceServer().authenticationEntryPoint(restAuthenticationEntryPoint);
        http.authorizeExchange()
                .pathMatchers(ArrayUtil.toArray(ignoreUrlsConfig.getUrls(), String.class)).permitAll()//白名单配置
                .pathMatchers("/login", "/new/login", "/webjars/**",
                        "/js/**", "/config/**", "/images/**", "/css/**", "/commonlib/**", "/thirdlibs/**",
                        "/favicon.ico", "/loginServer/**", "/randCodeImage/**",
                        "/oauth/**", "*.js", "/**/*.json", "/**/*.css", "/**/*.js", "/portal/**", "/**/*.map", "/**/*.html",
                        "/**/*.png", "uum/region/enum/**").permitAll()
                .anyExchange().access(authorizationManager)//鉴权管理器配置
                .and().exceptionHandling()
                .accessDeniedHandler(restfulAccessDeniedHandler)//处理未授权
                .authenticationEntryPoint(restAuthenticationEntryPoint)//处理未认证
                .and().headers().frameOptions().disable() //允许iframe
        ;

        return http.build();
    }

CorsFilter定义：

@Configuration
public class CorsFilter implements WebFilter {

    @Override
    public Mono<Void> filter(ServerWebExchange ctx, WebFilterChain chain) {
        ServerHttpRequest request = ctx.getRequest();
        if (CorsUtils.isCorsRequest(request)) {
            ServerHttpResponse response = ctx.getResponse();
            HttpHeaders headers = response.getHeaders();
            headers.set(HttpHeaders.ACCESS_CONTROL_ALLOW_ORIGIN, "*");
            headers.add(HttpHeaders.ACCESS_CONTROL_ALLOW_HEADERS, "*");
            headers.add(HttpHeaders.ACCESS_CONTROL_ALLOW_METHODS, "");
            headers.add(HttpHeaders.ACCESS_CONTROL_ALLOW_CREDENTIALS, "false");
            headers.add(HttpHeaders.ACCESS_CONTROL_EXPOSE_HEADERS, "*");
            headers.add(HttpHeaders.ACCESS_CONTROL_MAX_AGE, "3600");
            if (request.getMethod() == HttpMethod.OPTIONS) {
                response.setStatusCode(HttpStatus.OK);
                return Mono.empty();
            }
        }
        return chain.filter(ctx);
    }

# 问题二

# 网关报413
  1. Request header fields too large（header超过限制）
  2. Request Entity Too Large（params超过限制）

解决方法：

修改Netty配置文件

新建NettyConfiguration文件

package com.sun.gateway.config;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.web.embedded.netty.NettyReactiveWebServerFactory;
import org.springframework.boot.web.server.WebServerFactoryCustomizer;
import org.springframework.stereotype.Component;

/**
 * @author sungang
 * @date 2021/9/13 7:01 下午
 *
 */

@Component
public class NettyConfiguration implements WebServerFactoryCustomizer<NettyReactiveWebServerFactory> {

    @Value("${server.max-initial-line-length:1000485760}")
    private int maxInitialLingLength;

    @Override
    public void customize(NettyReactiveWebServerFactory container) {
        //處理Params中傳遞數據過大問題（但好像和header不能同時修改，過大的參數推薦用json處理）
        container.addServerCustomizers(
                httpServer -> httpServer.httpRequestDecoder(
                        httpRequestDecoderSpec -> httpRequestDecoderSpec.maxInitialLineLength(maxInitialLingLength)
                )
        );
        //處理Header中 token參數過大問題
        container.addServerCustomizers(
                httpServer -> httpServer.httpRequestDecoder(
                        httpRequestDecoderSpec -> httpRequestDecoderSpec.maxHeaderSize(1000485760)
                )
        );
    }

}

# 解决问题

# header头传递token过大

权限控制问题，spring gateway +oauth2.0 ，JWT token过大
