二.创建leadnews-wemedia和leadnews-wemedia-gateway

?

?

①:资料中找到heima-leadnews-wemedia.zip解压

拷贝到heima-leadnews-service工程下,并指定子模块

执行leadnews-wemedia.sql脚本

添加对应的nacos配置

spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/leadnews_wemedia?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
    username: root
    password: root
# 设置Mapper接口所对应的XML文件位置,如果你在Mapper接口中有自定义方法,需要进行该配置
mybatis-plus:
  mapper-locations: classpath*:mapper/*.xml
  # 设置别名包扫描路径,通过该属性可以给包中的类注册别名
  type-aliases-package: com.heima.model.media.pojos

②:资料中找到heima-leadnews-wemedia-gateway.zip解压

拷贝到heima-leadnews-gateway工程下,并指定子模块

添加对应的nacos配置

spring:
  cloud:
    gateway:
      globalcors:
        cors-configurations:
          '[/**]': # 匹配所有请求
            allowedOrigins: "*" #跨域处理 允许所有的域
            allowedMethods: # 支持的方法
              - GET
              - POST
              - PUT
              - DELETE
      routes:
        # 平台管理
        - id: wemedia
          uri: lb://leadnews-wemedia
          predicates:
            - Path=/wemedia/**
          filters:
            - StripPrefix= 1

③:在资料中找到类文件夹

拷贝wemedia文件夹到heima-leadnews-model模块下的com.heima.model

?

?

通过nginx的虚拟主机功能,使用同一个nginx访问多个项目

搭建步骤:

①:资料中找到wemedia-web.zip解压

②:在nginx中leadnews.conf目录中新增heima-leadnews-wemedia.conf文件

  • 网关地址修改(localhost:51602)

  • 前端项目目录修改(wemedia-web解压的目录)

  • 访问端口修改(8802)

upstream  heima-wemedia-gateway{
    server localhost:51602;
}

server {
	listen 8802;
	location / {
		root D:/workspace/wemedia-web/;
		index index.html;
	}
	
	location ~/wemedia/MEDIA/(.*) {
		proxy_pass http://heima-wemedia-gateway/$1;
		proxy_set_header HOST $host;  # 不改变源请求头的值
		proxy_pass_request_body on;  #开启获取请求体
		proxy_pass_request_headers on;  #开启获取请求头
		proxy_set_header X-Real-IP $remote_addr;   # 记录真实发出请求的客户端IP
		proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;  #记录代理信息
	}
}

?

③:启动nginx,启动自媒体微服务和对应网关

④:联调测试登录功能

?

?三.导入素材实体类:

package com.heima.model.wemedia.pojos;

import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import lombok.Data;

import java.io.Serializable;
import java.util.Date;

/**

 * 自媒体图文素材信息表
 * </p>
 *
 * @author itheima
 */
@Data
@TableName("wm_material")
public class WmMaterial implements Serializable {

    private static final long serialVersionUID = 1L;

    /**
     * 主键
     */
    @TableId(value = "id", type = IdType.AUTO)
    private Integer id;

    /**
     * 自媒体用户ID
     */
    @TableField("user_id")
    private Integer userId;

    /**
     * 图片地址
     */
    @TableField("url")
    private String url;

    /**
     * 素材类型
            0 图片
            1 视频
     */
    @TableField("type")
    private Short type;

    /**
     * 是否收藏
     */
    @TableField("is_collection")
    private Short isCollection;

    /**
     * 创建时间
     */
    @TableField("created_time")
    private Date createdTime;

}

?四.素材图片上传

?4.1在gateway中创建过滤器

package com.heima.wemedia.gateway.filter;


import com.heima.wemedia.gateway.util.AppJwtUtil;
import io.jsonwebtoken.Claims;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang.StringUtils;
import org.springframework.cloud.gateway.filter.GatewayFilterChain;
import org.springframework.cloud.gateway.filter.GlobalFilter;

import reactor.core.publisher.Mono;

@Component
@Slf4j
public class AuthorizeFilter implements Ordered, GlobalFilter {
    @Override
    public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
        //1.获取request和response对象
        ServerHttpRequest request = exchange.getRequest();
        ServerHttpResponse response = exchange.getResponse();

        //2.判断是否是登录
        if(request.getURI().getPath().contains("/login")){
            //放行
            return chain.filter(exchange);
        }

        //3.获取token
        String token = request.getHeaders().getFirst("token");

        //4.判断token是否存在
        if(StringUtils.isBlank(token)){
            response.setStatusCode(HttpStatus.UNAUTHORIZED);
            return response.setComplete();
        }

        //5.判断token是否有效
        try {
            Claims claimsBody = AppJwtUtil.getClaimsBody(token);
            //是否是过期
            int result = AppJwtUtil.verifyToken(claimsBody);
            if(result == 1 || result  == 2){
                response.setStatusCode(HttpStatus.UNAUTHORIZED);
                return response.setComplete();
            }
            //获取用户信息
            Object userId = claimsBody.get("id");
            //将id存到header中
            request.mutate().headers(headers -> headers.add("userId",userId.toString())).build();
            //重置请求
            exchange.mutate().request(request);


        } catch (Exception e) {
            e.printStackTrace();
        }

        //6.放行
        return chain.filter(exchange);
    }

    /**
     * 优先级设置  值越小  优先级越高
     * @return
     */
    @Override
    public int getOrder() {
        return 0;
    }
}

4.2在wemedia中创建拦截器

?

package com.heima.wemedia.interceptor;

import com.heima.model.wemedia.pojos.WmUser;
import com.heima.utils.thread.WmThreadLocalUtil;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Optional;
@Slf4j
public class WmTokenInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        //得到header中的信息
        String userId = request.getHeader("userId");
        Optional<String> optional = Optional.ofNullable(userId);
        if(optional.isPresent()){
            //把用户id存入threadloacl中
            WmUser wmUser = new WmUser();
            wmUser.setId(Integer.valueOf(userId));
            WmThreadLocalUtil.setUser(wmUser);
            log.info("wmTokenFilter设置用户信息到threadlocal中...");
        }

        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
        log.info("清理threadlocal...");
        WmThreadLocalUtil.clear();
    }
}

4.3WmThreadLocalUtil工具类

package com.heima.utils.thread;

import com.heima.model.wemedia.pojos.WmUser;

public class WmThreadLocalUtil {

    private final static ThreadLocal<WmUser> WM_USER_THREAD_LOCAL = new ThreadLocal<>();

    /**
     * 添加用户
     * @param wmUser
     */
    public static void  setUser(WmUser wmUser){
        WM_USER_THREAD_LOCAL.set(wmUser);
    }

    /**
     * 获取用户
     */
    public static WmUser getUser(){
        return WM_USER_THREAD_LOCAL.get();
    }

    /**
     * 清理用户
     */
    public static void clear(){
        WM_USER_THREAD_LOCAL.remove();
    }
}

4.5.4配置

首先要导入oss-starter依赖

<!--    minio-->
    <dependencies>

        <dependency>
            <groupId>com.common.oss</groupId>
            <artifactId>common-oss-starter</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
    </dependencies>

然后在nacos中添加配置

minio:
  endpoint: http://192.168.81.128:9000
  access-key: minio
  bucket: leadnews
  secret-key: dodo123456

4.6测试图片上传

在图片上传之前一定要记得先登录,否则会报空指针异常

图片上传成功并且回显了,下面看一下Minio中的图片:

?

?数据库中也有该图片,图片上传功能完结!

五.素材列表查询

5.1接口

说明
接口路径/api/v1/material/list
请求方式POST
参数WmMaterialDto
响应结果ResponseResult

?WmMaterialDto :

@Data
public class WmMaterialDto extends PageRequestDto {

    /**
     * 1 收藏
     * 0 未收藏
     */
    private Short isCollection;
}
{
  "host":null,
  "code":200,
  "errorMessage":"操作成功",
  "data":[
    {
    "id":52,
      "userId":1102,

    },
    ....
  ],
  "currentPage":1,
  "size":20,
  "total":0
}

5.2业务层

在WmMaterialService中新增方法

/**
     * 素材列表查询
     * @param dto
     * @return
     */
public ResponseResult findList( WmMaterialDto dto);

实现方法:

/**
     * 素材列表查询
     * @param dto
     * @return
     */
@Override
public ResponseResult findList(WmMaterialDto dto) {

    //1.检查参数
    dto.checkParam();

    //2.分页查询
    IPage page = new Page(dto.getPage(),dto.getSize());
    LambdaQueryWrapper<WmMaterial> lambdaQueryWrapper = new LambdaQueryWrapper<>();
    //是否收藏
    if(dto.getIsCollection() != null && dto.getIsCollection() == 1){
        lambdaQueryWrapper.eq(WmMaterial::getIsCollection,dto.getIsCollection());
    }

    //按照用户查询
    lambdaQueryWrapper.eq(WmMaterial::getUserId,WmThreadLocalUtil.getUser().getId());

    //按照时间倒序
    lambdaQueryWrapper.orderByDesc(WmMaterial::getCreatedTime);


    page = page(page,lambdaQueryWrapper);

    //3.结果返回
    ResponseResult responseResult = new PageResponseResult(dto.getPage(),dto.getSize(),(int)page.getTotal());
    responseResult.setData(page.getRecords());
    return responseResult;
}

5.3:控制器

@PostMapping("/list")
public ResponseResult findList(@RequestBody WmMaterialDto dto){
    return wmMaterialService.findList(dto);
}

?⑤:在自媒体引导类中天mybatis-plus的分页拦截器

@Bean
public MybatisPlusInterceptor mybatisPlusInterceptor() {
    MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
    interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
    return interceptor;
}
