一、网关相关配置
1、在pom.xml引入依赖
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
<parent>
<artifactId>infrastructure</artifactId>
<groupId>com.javaclimb</groupId>
<version>0.0.1-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>api_gateway</artifactId>
<dependencies>
<!-- 网关 -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-gateway</artifactId>
</dependency>
<!--服务注册-->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>
<dependency>
<groupId>com.javaclimb</groupId>
<artifactId>common_util</artifactId>
<version>0.0.1-SNAPSHOT</version>
<!-- 排除 spring-boot-starter-web, 否则和 gateway 中的 webflux 冲突 -->
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</exclusion>
</exclusions>
</dependency>
<!--将随着spring-boot-starter-web排除的servlet-api添加回来 -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>4.0.1</version>
<scope>provided</scope>
</dependency>
<!--gson-->
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
</project>
2、application.yml
server:
port: 8090
spring:
profiles:
active: dev
application:
name: infrastructure-apigateway
cloud:
# nacos 服务
nacos:
discovery:
server-addr: 127.0.0.1:8848
gateway:
discovery:
locator:
# gateway 可以发现 nacos 中的微服务
enabled: true
routes:
- id: service-edu # 随便起
# uri: http://localhost:9110 # 目标路由
# 目标路由,必须和 nacos 中微服务名称一样, lb -> 以负载均衡的方式访问
uri: lb://service-edu
predicates:
# 路径断言,只要这个条件成立,就转发到上面的地址
- Path=/user/**, /*/edu/**
- id: service-cms
uri: lb://service-cms
predicates:
- Path=/*/cms/**
# 过滤器
filters:
- SetStatus=250 # 修改响应状态码为 250
- id: service-oss
uri: lb://service-oss
predicates:
- Path=/*/oss/**
- id: service-trade
uri: lb://service-trade
predicates:
- Path=/*/trade/**
- id: service-ucenter
uri: lb://service-ucenter
predicates:
- Path=/*/ucenter/**
- id: service-vod
uri: lb://service-vod
predicates:
- Path=/*/vod/**
- id: service-statistics
uri: lb://service-statistics
predicates:
- Path=/*/statistics/**
- id: service-acl
uri: lb://service-acl
predicates:
- Path=/*/acl/**
3、编写启动类
package com.stu.infrastructure;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
/******************************
* 用途说明:
* 作者姓名: Administrator
* 创建时间: 2022-07-27 22:56
******************************/
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
@EnableDiscoveryClient
public class ApiGatewayApplication {
public static void main(String[] args) {
SpringApplication.run(ApiGatewayApplication.class, args);
}
}
4、网关解决跨域问题
package com.stu.infrastructure.confing;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.reactive.CorsWebFilter;
import org.springframework.web.util.pattern.PathPatternParser;
/******************************
* 用途说明:
* 作者姓名: Administrator
* 创建时间: 2022-07-27 23:16
******************************/
@Configuration
public class CorsConfig {
@Bean
public CorsWebFilter corsFilter() {
CorsConfiguration config = new CorsConfiguration();
// #允许向该服务器提交请求的URI，*表示全部允许，在SpringMVC中，如果设成*，会自动转成当前请求头中的Origin
config.addAllowedOrigin("*");
// #允许访问的头信息,*表示全部
config.addAllowedHeader("*");
// 允许提交请求的方法类型，*表示全部允许
config.addAllowedMethod("*");
org.springframework.web.cors.reactive.UrlBasedCorsConfigurationSource source =
new org.springframework.web.cors.reactive.UrlBasedCorsConfigurationSource(new PathPatternParser());
source.registerCorsConfiguration("/**", config);
return new CorsWebFilter(source);
}
}
5、全局Filter，统一处理会员登录与外部不允许访问的服务
package com.stu.infrastructure.filter;
/******************************
* 用途说明:
* 作者姓名: Administrator
* 创建时间: 2022-07-27 23:35
******************************/
import com.stu.service.base.utils.JwtUtils;
import com.google.gson.JsonObject;
import org.springframework.cloud.gateway.filter.GatewayFilterChain;
import org.springframework.cloud.gateway.filter.GlobalFilter;
import org.springframework.core.Ordered;
import org.springframework.core.io.buffer.DataBuffer;
import org.springframework.http.server.reactive.ServerHttpRequest;
import org.springframework.http.server.reactive.ServerHttpResponse;
import org.springframework.stereotype.Component;
import org.springframework.util.AntPathMatcher;
import org.springframework.web.server.ServerWebExchange;
import reactor.core.publisher.Mono;
import java.nio.charset.StandardCharsets;
import java.util.List;
@Component
public class AuthGlobalFilter implements GlobalFilter, Ordered {
@Override
public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
// 获取请求对象
ServerHttpRequest request = exchange.getRequest();
String path = request.getURI().getPath();
// 匹配路由
AntPathMatcher antPathMatcher = new AntPathMatcher();
// 判断路径中如果含有 /api/**/auth/**,则需要鉴权
if (antPathMatcher.match("/api/**/auth/**", path)) {
// 获取 token
List<String> tokenList = request.getHeaders().get("token");
// 没有 token
if (tokenList == null) {
ServerHttpResponse response = exchange.getResponse();
// 鉴权失败
return this.out(response);
}
// token 检验失败
boolean isCheck = JwtUtils.checkJwtToken(tokenList.get(0));
if (!isCheck) {
ServerHttpResponse response = exchange.getResponse();
// 鉴权失败
return this.out(response);
}
}
// 放行: 使用过滤器链,将请求继续向下传递
return chain.filter(exchange);
}
/**
* 定义当前过滤器的优先级
* - 值越小, 优先级越高
*/
@Override
public int getOrder() {
return 0;
}
/**
* 使用 webflux 输入请求信息
*/
private Mono<Void> out(ServerHttpResponse response) {
JsonObject message = new JsonObject();
message.addProperty("success", false);
message.addProperty("code", 28004);
message.addProperty("data", "");
message.addProperty("message", "鉴权失败");
byte[] bytes = message.toString().getBytes(StandardCharsets.UTF_8);
DataBuffer buffer = response.bufferFactory().wrap(bytes);
//指定编码，否则在浏览器中会中文乱码
response.getHeaders().add("Content-Type", "application/json;charset=UTF-8");
//输出http响应
return response.writeWith(Mono.just(buffer));
}
}
六、前端俩项目修改连接地址
把前端请求地址的端口修改位网关的接口
