RuoYi-App实现了与RuoYi-Vue后台完美对接，也能与RuoYi-Cloud完美对接。只需要简单修改一下，流程如下：

1、RuoYi-Cloud微服务版本后端新增跨域支持类CorsConfig.java

package com.ruoyi.gateway.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.HttpStatus;
import org.springframework.http.server.reactive.ServerHttpRequest;
import org.springframework.http.server.reactive.ServerHttpResponse;
import org.springframework.web.cors.reactive.CorsUtils;
import org.springframework.web.server.ServerWebExchange;
import org.springframework.web.server.WebFilter;
import org.springframework.web.server.WebFilterChain;
import reactor.core.publisher.Mono;

/**
 * 跨域配置
 * 
 * @author ruoyi
 */
@Configuration
public class CorsConfig
{
    /**
     * 这里为支持的请求头，如果有自定义的header字段请自己添加
     */
    private static final String ALLOWED_HEADERS = "X-Requested-With, Content-Type, Authorization, credential, X-XSRF-TOKEN, token, Admin-Token, App-Token";
    private static final String ALLOWED_METHODS = "GET,POST,PUT,DELETE,OPTIONS,HEAD";
    private static final String ALLOWED_ORIGIN = "*";
    private static final String ALLOWED_EXPOSE = "*";
    private static final String MAX_AGE = "18000L";

    @Bean
    public WebFilter corsFilter()
    {
        return (ServerWebExchange ctx, WebFilterChain chain) -> {
            ServerHttpRequest request = ctx.getRequest();
            if (CorsUtils.isCorsRequest(request))
            {
                ServerHttpResponse response = ctx.getResponse();
                HttpHeaders headers = response.getHeaders();
                headers.add("Access-Control-Allow-Headers", ALLOWED_HEADERS);
                headers.add("Access-Control-Allow-Methods", ALLOWED_METHODS);
                headers.add("Access-Control-Allow-Origin", ALLOWED_ORIGIN);
                headers.add("Access-Control-Expose-Headers", ALLOWED_EXPOSE);
                headers.add("Access-Control-Max-Age", MAX_AGE);
                headers.add("Access-Control-Allow-Credentials", "true");
                if (request.getMethod() == HttpMethod.OPTIONS)
                {
                    response.setStatusCode(HttpStatus.OK);
                    return Mono.empty();
                }
            }
            return chain.filter(ctx);
        };
    }
}

2、RuoYi-App编辑api/login.js，修改几个接口。

import request from '@/utils/request'

// 登录方法
export function login(username, password, code, uuid) {
  const data = {
    username,
    password,
    code,
    uuid
  }
  return request({
    'url': '/auth/login',
    headers: {
      isToken: false
    },
    'method': 'post',
    'data': data
  })
}

// 获取用户详细信息
export function getInfo() {
  return request({
    'url': '/system/user/getInfo',
    'method': 'get'
  })
}

// 退出方法
export function logout() {
  return request({
    'url': '/auth/logout',
    'method': 'delete'
  })
}

// 获取验证码
export function getCodeImg() {
  return request({
    'url': '/code',
    headers: {
      isToken: false
    },
    method: 'get',
    timeout: 20000
  })
}

3、RuoYi-App编辑store/modules/user.js，修改一下token返回值。

// res.token 更换为 res.data.access_token
....
login(username, password, code, uuid).then(res => {
  setToken(res.data.access_token)
  commit('SET_TOKEN', res.data.access_token)
  resolve()
})
....

按照上述修改完成后我们就支持微服务了，微服务和分离版本接口基本上是一样的，都能互相通用。
