20、商品微服务-web层实现

2022-08-03 00:35:00 【无休止符】

目录

一、快速新建goods_web服务

1 - 新建项目goods_web

  • 参考之前的user_web服务：
    • 将项目拷贝过来，然后将不需要的删除，也可以直接跳过，下载之后的完整源码；以下介绍一些关键的修改
  • 使用目录的方式替换import：将user_web替换为goods_web
  • goods_web/api/goods/api_goods.go：新增一个List实现，不需要其他逻辑
    在这里插入图片描述
  • goods_web/initialize/init_router.go

在这里插入图片描述

  • nacos的namespace修改：这里以goods_web/config_zsz.yaml为例，另外2个自行修改
    在这里插入图片描述
host: '192.168.124.51'
port: 8848
namespace: 'b2f00e3b-4e22-4e87-8129-9c02b5f1220d'
user: 'nacos'
password: 'nacos'
dataid: 'goods_web.json'
group: 'zsz'
  • 克隆nacos配置：克隆user_web.json配置为goods_web.json，注意修改目标空间、DataId、Group
    在这里插入图片描述
{
    
  "name": "goods_web",
  "port": 8082,
  "goods_srv": {
    
    "name": "goods_srv"
  },
  "jwt": {
    
    "key": "VYLDYq3&hGWjWqF$K1ih"
  },
  "consul": {
    
    "host": "192.168.124.51",
    "port": 8500
  }
}

2 - 快速测试

二、商品列表接口

  • goods_web/api/goods/api_goods.go：实现List
func List(ctx *gin.Context) {
    
	fmt.Println("商品列表")
	//商品的列表
	 根据前端的请求参数构造request对象
	request := &proto.GoodsFilterRequest{
    }
	priceMin := ctx.DefaultQuery("pmin", "0")
	priceMinInt, _ := strconv.Atoi(priceMin)
	request.PriceMin = int32(priceMinInt)
	priceMax := ctx.DefaultQuery("pmax", "0")
	priceMaxInt, _ := strconv.Atoi(priceMax)
	request.PriceMax = int32(priceMaxInt)
	isHot := ctx.DefaultQuery("ih", "0")
	if isHot == "1" {
    
		request.IsHot = true
	}
	isNew := ctx.DefaultQuery("in", "0")
	if isNew == "1" {
    
		request.IsNew = true
	}
	isTab := ctx.DefaultQuery("it", "0")
	if isTab == "1" {
    
		request.IsTab = true
	}
	categoryId := ctx.DefaultQuery("c", "0")
	categoryIdInt, _ := strconv.Atoi(categoryId)
	request.TopCategory = int32(categoryIdInt)
	pages := ctx.DefaultQuery("p", "0")
	pagesInt, _ := strconv.Atoi(pages)
	request.Pages = int32(pagesInt)
	perNums := ctx.DefaultQuery("pnum", "0")
	perNumsInt, _ := strconv.Atoi(perNums)
	request.PagePerNums = int32(perNumsInt)
	keywords := ctx.DefaultQuery("q", "")
	request.KeyWords = keywords
	brandId := ctx.DefaultQuery("b", "0")
	brandIdInt, _ := strconv.Atoi(brandId)
	request.Brand = int32(brandIdInt)

	请求商品的service服务
	r, err := global.GoodsSrvClient.GoodsList(context.WithValue(context.Background(), "ginContext", ctx), request)
	if err != nil {
    
		zap.S().Errorw("[List] 查询 【商品列表】失败")
		HandleGrpcErrorToHttp(err, ctx)
		return
	}

	reMap := map[string]interface{
    }{
    
		"total": r.Total,
	}

	goodsList := make([]interface{
    }, 0)
	for _, value := range r.Data {
    
		goodsList = append(goodsList, map[string]interface{
    }{
    
			"id":          value.Id,
			"name":        value.Name,
			"goods_brief": value.GoodsBrief,
			"desc":        value.GoodsDesc,
			"ship_free":   value.ShipFree,
			"images":      value.Images,
			"desc_images": value.DescImages,
			"front_image": value.GoodsFrontImage,
			"shop_price":  value.ShopPrice,
			"category": map[string]interface{
    }{
    
				"id":   value.Category.Id,
				"name": value.Category.Name,
			},
			"brand": map[string]interface{
    }{
    
				"id":   value.Brand.Id,
				"name": value.Brand.Name,
				"logo": value.Brand.Logo,
			},
			"is_hot":  value.IsHot,
			"is_new":  value.IsNew,
			"on_sale": value.OnSale,
		})
	}
	reMap["data"] = goodsList

	ctx.JSON(http.StatusOK, reMap)
}

三、goods_web服务注册与注销

  • 需求分析：提高注册中心的扩展性，比如之后不想用consul，想换nacos、etcd等
  • nacos配置：
    在这里插入图片描述

  "host": "192.168.78.1",
  "name": "goods_web",
  "port": 8082,

  },
  "consul": {

	ShopPrice   float32  `form:"shop_price" json:"shop_price" binding:"required,min=0"`
	GoodsBrief  string   `form:"goods_brief" json:"goods_brief" binding:"required,min=3"`
	Images      []string `form:"images" json:"images" binding:"required,min=1"`
	DescImages  []string `form:"desc_images" json:"desc_images" binding:"required,min=1"`
	ShipFree    *bool    `form:"ship_free" json:"ship_free" binding:"required"`
	FrontImage  string   `form:"front_image" json:"front_image" binding:"required,url"`
	Brand       int32    `form:"brand" json:"brand" binding:"required"`
}

		//GoodsRouter.POST("", middlewares.JWTAuth(), middlewares.IsAdminAuth(), goods.New) //该接口需要管理员权限
		GoodsRouter.POST("", goods.New) // 我们测试先将这2个接口权限关闭掉
	}
}
  • goods_web/api/goods/api_goods.go
func New(ctx *gin.Context) {
    
	goodsForm := forms.GoodsForm{
    }
	if err := ctx.ShouldBindJSON(&goodsForm); err != nil {
    
		HandleValidatorError(ctx, err)
		return
	}

		GoodsFrontImage: goodsForm.FrontImage,
		CategoryId:      goodsForm.CategoryId,
		BrandId:         goodsForm.Brand,
	})
	if err != nil {
    
		HandleGrpcErrorToHttp(err, ctx)
		return
	}

	//如何设置库存
	//TODO 商品的库存 - 分布式事务
	ctx.JSON(http.StatusOK, rsp)

4 - 商品分类接口

  • goods_web/router/router_category.go
package router

import (
	"github.com/gin-gonic/gin"
	"web_api/goods_web/api/category"
)

func InitCategoryRouter(Router *gin.RouterGroup) {
    
	CategoryRouter := Router.Group("categorys")
	{
    
		CategoryRouter.GET("", category.List)          // 商品类别列表页
		CategoryRouter.DELETE("/:id", category.Delete) // 删除分类
		CategoryRouter.GET("/:id", category.Detail)    // 获取分类详情
		CategoryRouter.POST("", category.New)          //新建分类
		CategoryRouter.PUT("/:id", category.Update)    //修改分类信息
	}
}
  • goods_web/forms/form_category.go
package forms

type CategoryForm struct {
    
	Name           string `form:"name" json:"name" binding:"required,min=3,max=20"`
	ParentCategory int32  `form:"parent" json:"parent"`
	Level          int32  `form:"level" json:"level" binding:"required,oneof=1 2 3"`
	IsTab          *bool  `form:"is_tab" json:"is_tab" binding:"required"`
}

type UpdateCategoryForm struct {
    
	Name  string `form:"name" json:"name" binding:"required,min=3,max=20"`
	IsTab *bool  `form:"is_tab" json:"is_tab"`
}
  • goods_web/api/category/category.go：代码太多，就贴下方法图片，具体查看完整源码
    在这里插入图片描述

这里总结下套路：
1、先添加form表单的struct
2、实现API方法
3、添加router

5 - 轮播图接口

  • goods_web/forms/form_banner.go
package forms

type BannerForm struct {
    
	Image string `form:"image" json:"image" binding:"url"`
	Index int    `form:"index" json:"index" binding:"required"`
	Url   string `form:"url" json:"url" binding:"url"`
}
  • goods_web/api/banners/api_banner.go
    在这里插入图片描述
  • goods_web/router/router_banner.go
package router

import (
	"github.com/gin-gonic/gin"
	"web_api/goods_web/api/banners"
)

func InitBannerRouter(Router *gin.RouterGroup) {
    
	BannerRouter := Router.Group("banners")
	{
    
		BannerRouter.GET("", banners.List) // 轮播图列表页
		//BannerRouter.DELETE("/:id", middlewares.JWTAuth(), middlewares.IsAdminAuth(), banners.Delete) // 删除轮播图
		//BannerRouter.POST("", middlewares.JWTAuth(), middlewares.IsAdminAuth(), banners.New) //新建轮播图
		//BannerRouter.PUT("/:id", middlewares.JWTAuth(), middlewares.IsAdminAuth(), banners.Update) //修改轮播图信息
		BannerRouter.DELETE("/:id", banners.Delete) // 删除轮播图
		BannerRouter.POST("", banners.New)          //新建轮播图
		BannerRouter.PUT("/:id", banners.Update)    //修改轮播图信息
	}
}

6 - 品牌接口

  • goods_web/api/brands/api_brand.go

在这里插入图片描述

  • goods_web/forms/form_brand.go
package forms

type BrandForm struct {
    
	Name string `form:"name" json:"name" binding:"required,min=3,max=10"`
	Logo string `form:"logo" json:"logo" binding:"url"`
}

type CategoryBrandForm struct {
    
	CategoryId int `form:"category_id" json:"category_id" binding:"required"`
	BrandId    int `form:"brand_id" json:"brand_id" binding:"required"`
}
  • goods_web/router/router_brand.go
package router

import (
	"github.com/gin-gonic/gin"
	"web_api/goods_web/api/brands"
)

// InitBrandRouter
//1. 商品的api接口开发完成
//2. 图片的坑
func InitBrandRouter(Router *gin.RouterGroup) {
    
	BrandRouter := Router.Group("brands")
	{
    
		BrandRouter.GET("", brands.BrandList)          // 品牌列表页
		BrandRouter.DELETE("/:id", brands.DeleteBrand) // 删除品牌
		BrandRouter.POST("", brands.NewBrand)          //新建品牌
		BrandRouter.PUT("/:id", brands.UpdateBrand)    //修改品牌信息
	}

	CategoryBrandRouter := Router.Group("categorybrands")
	{
    
		CategoryBrandRouter.GET("", brands.CategoryBrandList)          // 类别品牌列表页
		CategoryBrandRouter.DELETE("/:id", brands.DeleteCategoryBrand) // 删除类别品牌
		CategoryBrandRouter.POST("", brands.NewCategoryBrand)          //新建类别品牌
		CategoryBrandRouter.PUT("/:id", brands.UpdateCategoryBrand)    //修改类别品牌
		CategoryBrandRouter.GET("/:id", brands.GetCategoryBrandList)   //获取分类的品牌
	}
}

六、完整源码

  • 完整源码下载：mxshop_srvsV8.3.rar
  • 源码说明：（nacos的ip配置自行修改，全局变量DEV_CONFIG设置：1=zsz，2=comp，3=home）
    • goods_srv/model/sql/mxshop_goods.sql：包含了建表语句
    • other_import/api.json：YApi的导入文件
    • other_import/nacos_config_export_user.zip：nacos的user配置集导入文件
    • other_import/nacos_config_export_goods.zip：nacos的goods配置集导入文件

附：YApi快速添加接口方法

  • 这里以轮播图举例
    • 一开始我们还没有轮播图的数据，这里有4个接口
      在这里插入图片描述
  • 我们可以先实现添加轮播图的接口

在这里插入图片描述

在这里插入图片描述

  • 反复编辑 -> 运行几次：数据库数据就有了
    在这里插入图片描述
  • 这时候我们再查询轮播图列表数据就有了
    在这里插入图片描述
  • 将返回的body中的json数据复制下，编辑接口-轮播图列表
    • 在返回数据设置这选择导入，粘贴复制的json数据，就会自动帮我们生成返回数据的json
    • 而我们需要做的仅仅就是修改下备注就可以了
      在这里插入图片描述
