SpringCloud-Gateway网关实现入参统一解密

1.添加依赖

剩下的依赖自行添加...

    
            org.springframework.cloud
            spring-cloud-starter-gateway
        

2.创建配置文件

这里我使用了Nacos，使用时需要添加Nacos依赖 及配置

server:
  port: 8081

spring:
  application:
    name: itvgetway
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
      config:
        server-addr: 127.0.0.1:8848
        file-extension: yaml
    gateway:
      discovery:
        locator:
          enabled: true
      routes:
        - id: smsinterface
          uri: lb://smsinterfacecloud
          predicates:
            - Path=/smsinterface/**
          filters:
           - RequestSign

3.过滤器

直接看代码

package com.example.itvgetway.filter;

import com.alibaba.fastjson.JSONObject;
import com.example.itvcommoncore.commons.AESCoder;
import org.springframework.cloud.gateway.filter.GatewayFilter;
import org.springframework.cloud.gateway.filter.GatewayFilterChain;
import org.springframework.cloud.gateway.filter.factory.AbstractGatewayFilterFactory;
import org.springframework.core.Ordered;
import org.springframework.http.server.reactive.ServerHttpRequest;
import org.springframework.stereotype.Component;
import org.springframework.util.MultiValueMap;
import org.springframework.web.server.ServerWebExchange;
import org.springframework.web.util.UriComponentsBuilder;
import reactor.core.publisher.Mono;
import java.net.URLEncoder;
import java.net.URI;
import java.nio.charset.StandardCharsets;


@Component
public class RequestSignGatewayFilterFactory extends AbstractGatewayFilterFactory
