【Go】十八、http 调用服务的编写

http_0">http接口框架的搭建

这个http接口框架的搭建参考之前的全量搭建，这里是快速搭建的模式：

直接对已有的http模块进行复制修改，主要修改点在于 proto部分与api、router 部分，剩余的要针对进行修改模块名称。

接口的具体编写

在 api/goods/goods.go 中编写具体的代码：

例如：goods的List接口的开发：

func List(ctx *gin.Context) {request := &proto.GoodsFilterRequest{}priceMin := ctx.DefaultQuery("pmin", "0") // 取出设定的最小价格,默认为 0priceMinInt, _ := 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 = keywordsbrandId := ctx.DefaultQuery("b", "0")brandIdInt, _ := strconv.Atoi(brandId)request.Brand = int32(brandIdInt)r, err := global.GoodsSrvClient.GoodsList(context.Background(), 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,"data":  r.Data,}ctx.JSON(http.StatusOK, reMap)
}

但是呢，这种写法存在一定的问题，就是在http接口中未存在对于后端数据的修正，这样子不便于前端与后端的数据对接，所以我们在 http 端一般可以做一个修改确定：

	reMap := map[string]interface{}{"total": r.Total,}// 这里一般会进行数据处理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"] = goodsListctx.JSON(http.StatusOK, reMap)

注册中心内容抽取

有时候，我们的项目不是完全基于某一个注册中心，我们不希望将注册中心的逻辑集成在 main文件中，我们希望我们的项目具有快速替换性，这个时候就需要我们将注册中心的内容抽取出来

注册中心服务注册

我们在 util 包下创建一个 register 包，再在 register包下创建 consul包，再在 consul包下创建register.go：

package consulimport ("fmt""github.com/hashicorp/consul/api""mxshop-api/goods-web/global"
)// 重新配置Register，令其单独拎出来
// 注册类，这是一个类
type Registry struct {Host stringPort int
}// 这个是类的能力，能干什么
type RegistryClient interface {Register(address string, port int, name string, tags []string, id string) errorDeRegister(serviceId string) error
}func NewRegistryClient(host string, port int) RegistryClient {return &Registry{Host: host,Port: port,}
}func (r *Registry) Register(address string, port int, name string, tags []string, id string) error {cfg := api.DefaultConfig()cfg.Address = fmt.Sprintf("%s:%d", r.Host, r.Port) // consul 的地址client, err := api.NewClient(cfg)if err != nil {panic(err)}// 生成 consul 的注册对象// 配置基础信息registration := new(api.AgentServiceRegistration)registration.Name = nameregistration.ID = idregistration.Tags = tagsregistration.Port = portregistration.Address = address// 配置检查对象，也就是健康检查机制check := &api.AgentServiceCheck{HTTP:                           fmt.Sprintf("http://%s:%d/health", global.ServerConfig.Host, global.ServerConfig.Port), // 发送 GET 请求来进行健康检查，服务的地址Timeout:                        "5s",                                                                                   // 每次健康检查中，多久没有回复视为健康检查失败Interval:                       "5s",                                                                                   // 进行健康检查的频率DeregisterCriticalServiceAfter: "10s",                                                                                  // 不健康服务允许存活的时间，当一个服务被检查为不健康时，若 10s 内其没有转为健康，则将其从服务中删除}// 将检查对象配置进 consul 的注册对象 registration 中registration.Check = check// 将配置的 consul 注册进去err = client.Agent().ServiceRegister(registration)client.Agent().ServiceDeregister(name)if err != nil {panic(err)}return nil}func (r *Registry) DeRegister(serviceId string) error {return nil
}

在这个程序中，我们要注意的是程序的注册与鸭子类型的实际应用，同时理解golang的设计思想

main.go

	// 动态配置 Consul 相关信息register_client := consul.NewRegistryClient(global.ServerConfig.ConsulInfo.Host, global.ServerConfig.ConsulInfo.Port)serviceId := fmt.Sprintf("%s", uuid.NewV4())err := register_client.Register(global.ServerConfig.Host, global.ServerConfig.Port, global.ServerConfig.Name, global.ServerConfig.Tags, serviceId)if err != nil {zap.S().Panic("服务注册失败", err.Error())}

注册中心服务注销

优雅的利用go 的队列机制注销服务

	quit := make(chan os.Signal)// 如果接收到了 kill 或 ctrl C，则进入quitsignal.Notify(quit, syscall.SIGINT, syscall.SIGTERM)<-quitif err = register_client.DeRegister(serviceId); err != nil {zap.S().Panic("注销失败：", err.Error())} else {zap.S().Panic("注销成功")}

新建商品接口

在router中添加路由，这个商品需要管理员权限才可以新建

func InitGoodsRouter(Router *gin.RouterGroup) {// 这样就需要 /user/list 才可以进行访问了GoodsRouter := Router.Group("goods"){// 在这里添加拦截器的作用响应位置GoodsRouter.GET("", goods.List)GoodsRouter.POST("", middlewares.JWTAuth(), middlewares.IsAdminAuth(), goods.New)}
}

同时我们在 api/goods.go 中添加新建商品的接口

func New(ctx *gin.Context) {// 由于这里使用了 类似于 Vo 的感觉，所以先构建一个用来绑定获取到的前端数据goodsForm := forms.GoodsForm{}// 绑定 ShouldBind可以同时绑定form和json，这里就写的明确一点，视为json形式if err := ctx.ShouldBindJSON(&goodsForm); err != nil {HandleValidatorError(ctx, err)return}// 利用proto 从 grpc服务中获取所需的信息goodsClient := global.GoodsSrvClientrsp, err := goodsClient.CreateGoods(context.Background(), &proto.CreateGoodsInfo{Name:            goodsForm.Name,GoodsSn:         goodsForm.GoodsSn,Stocks:          goodsForm.Stocks,MarketPrice:     goodsForm.MarketPrice,ShopPrice:       goodsForm.ShopPrice,GoodsBrief:      goodsForm.GoodsBrief,GoodsDesc:       goodsForm.GoodsDesc,ShipFree:        *goodsForm.ShipFree,Images:          goodsForm.Images,DescImages:      goodsForm.DescImages,GoodsFrontImage: goodsForm.FrontImage,CategoryId:      goodsForm.CategoryId,BrandId:         goodsForm.Brand,})if err != nil {HandleGrpcErrorToHttp(err, ctx)return}// todo 如何设置库存ctx.JSON(http.StatusOK, rsp)
}

商品详情接口

在 router 中创建单独商品详情接口：

GoodsRouter.GET("/:id", goods.Detail) // 捕捉类似于/goods/123 的内容中的 123

func Detail(ctx *gin.Context) {// 获取拼接在 链接之后的参数id := ctx.Param("id") // 获取 /goods/123i, err := strconv.ParseInt(id, 10, 32)if err != nil {ctx.Status(http.StatusNotFound)return}// 发送 grpc 请求查询相关内容r, err := global.GoodsSrvClient.GetGoodsDetail(context.Background(), &proto.GoodInfoRequest{Id: int32(i),})if err != nil {api.HandleGrpcErrorToHttp(err, ctx)}rsp := map[string]interface{}{"id":          r.Id,"name":        r.Name,"goods_brief": r.GoodsBrief,"desc":        r.GoodsDesc,"ship_free":   r.ShipFree,"images":      r.Images,"desc_images": r.DescImages,"front_image": r.GoodsFrontImage,"shop_price":  r.ShopPrice,"category": map[string]interface{}{"id":   r.Category.Id,"name": r.Category.Name,},"brand": map[string]interface{}{"id":   r.Brand.Id,"name": r.Brand.Name,"logo": r.Brand.Logo,},"is_hot":  r.IsHot,"is_new":  r.IsNew,"on_sale": r.OnSale,}ctx.JSON(http.StatusOK, rsp)
}

删除商品接口

在 router 中创建删除商品的接口：

GoodsRouter.DELETE("/:id", middlewares.JWTAuth(), middlewares.IsAdminAuth(), goods.Delete)

func Delete(ctx *gin.Context) {id := ctx.Param("id")i, err := strconv.ParseInt(id, 10, 32)if err != nil {ctx.Status(http.StatusNotFound)return}_, err = global.GoodsSrvClient.DeleteGoods(context.Background(), &proto.DeleteGoodsInfo{Id: int32(i)})if err != nil {api.HandleGrpcErrorToHttp(err, ctx)return}ctx.Status(http.StatusOK)return
}

获取商品库存接口

库存接口正在开发中

在router 中新增接口

GoodsRouter.GET("/:id/stocks", goods.Stocks) // 获取商品库存

func Stocks(ctx *gin.Context) {id := ctx.Param("id")_, err := strconv.ParseInt(id, 10, 32)if err != nil {ctx.Status(http.StatusNotFound)return}// TODO 商品库存相关信息
}

更新商品状态接口

GoodsRouter.PATCH("/:id", middlewares.JWTAuth(), middlewares.IsAdminAuth(), goods.UpdateStatus)

func UpdateStatus(ctx *gin.Context) {id := ctx.Param("id")i, err := strconv.ParseInt(id, 10, 32)if err != nil {ctx.Status(http.StatusNotFound)return}goodsStatusForm := forms.GoodsStatusForm{}if err := ctx.ShouldBindJSON(&goodsStatusForm); err != nil {api.HandleValidatorError(ctx, err)return}if _, err = global.GoodsSrvClient.UpdateGoods(context.Background(), &proto.CreateGoodsInfo{Id:     int32(i),IsNew:  *goodsStatusForm.IsNew,IsHot:  *goodsStatusForm.IsHot,OnSale: *goodsStatusForm.OnSale,}); err != nil {api.HandleGrpcErrorToHttp(err, ctx)return}ctx.JSON(http.StatusOK, gin.H{"msg": "修改成功",})
}

更新商品接口

GoodsRouter.PUT("/:id", middlewares.JWTAuth(), middlewares.IsAdminAuth(), goods.Update)

func Update(ctx *gin.Context) {id := ctx.Param("id")i, err := strconv.ParseInt(id, 10, 32)if err != nil {ctx.Status(http.StatusNotFound)return}goodsForm := forms.GoodsForm{}if err = ctx.ShouldBindJSON(&goodsForm); err != nil {api.HandleValidatorError(ctx, err)return}if _, err = global.GoodsSrvClient.UpdateGoods(context.Background(), &proto.CreateGoodsInfo{Id:              int32(i),Name:            goodsForm.Name,GoodsSn:         goodsForm.GoodsSn,Stocks:          goodsForm.Stocks,MarketPrice:     goodsForm.MarketPrice,ShopPrice:       goodsForm.ShopPrice,GoodsBrief:      goodsForm.GoodsBrief,GoodsDesc:       goodsForm.GoodsDesc,ShipFree:        *goodsForm.ShipFree,Images:          goodsForm.Images,DescImages:      goodsForm.DescImages,GoodsFrontImage: goodsForm.FrontImage,CategoryId:      goodsForm.CategoryId,BrandId:         goodsForm.Brand,}); err != nil {api.HandleGrpcErrorToHttp(err, ctx)return}ctx.JSON(http.StatusOK, gin.H{"msg": "修改成功",})}

分类的相关接口

我们在做分类接口之前，意识到有三个接口是大家都共用的，分别是：removeTopStruct、HandleGrpcErrorToHttp、HandleValidatorError ，所以我们可以把这三个接口都抽到base.go 中：

base.go（在 api 包下创建的新接口）

package apiimport ("github.com/gin-gonic/gin""github.com/go-playground/validator/v10""google.golang.org/grpc/codes""google.golang.org/grpc/status""mxshop-api/goods-web/global""net/http""strings"
)func HandleGrpcErrorToHttp(err error, c *gin.Context) {// 将 grpc 的状态码转换为 http 的状态码if err != nil {if e, ok := status.FromError(err); ok {switch e.Code() {case codes.NotFound:c.JSON(http.StatusNotFound, gin.H{"msg": e.Message(),})case codes.Internal:c.JSON(http.StatusInternalServerError, gin.H{"msg": "内部错误",})case codes.InvalidArgument:c.JSON(http.StatusBadRequest, gin.H{"msg": "参数错误",})default:c.JSON(http.StatusInternalServerError, gin.H{"msg": "其他错误：" + e.Message(),})}}}
}// 在最后返回错误时调用，用来将返回中的对象名去掉
func RemoveTopStruct(fields map[string]string) map[string]string {rsp := map[string]string{}for field, err := range fields {rsp[field[strings.Index(field, ".")+1:]] = err // 将map中的 key 中的 . 前面的信息去掉}return rsp
}func HandleValidatorError(c *gin.Context, err error) {errs, ok := err.(validator.ValidationErrors)if !ok {c.JSON(http.StatusOK, gin.H{"msg": err.Error(),})}c.JSON(http.StatusBadRequest, gin.H{"msg": RemoveTopStruct(errs.Translate(global.Trans)),})return
}

创建所需表单

forms/category.go

package formstype 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"`
}

添加品牌API

注意这里的分页是不好的写法，正确的应该在service层中实现，所以这里不要参考，具体可以参考商品那里的接口

添加品牌Router

package routerimport ("github.com/gin-gonic/gin""mxshop-api/goods-web/api/brands"
)// 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}
}

品牌路由导入路由表

	ApiGroup := Router.Group("/g/v1")router2.InitGoodsRouter(ApiGroup)router2.InitCategoryRouter(ApiGroup)router2.InitBannerRouter(ApiGroup)router2.InitBrandRouter(ApiGroup)router2.InitHealthCheckRouter(Router.Group(""))
