安装gin框架(使用mod,makefile方式)

## 1 新建一个项目目录 ``` mkdir wages_service ``` ## 2 新建`Makefile`文件 ``` touch Makefile ``` 文件内容如下 ``` all: clean deps clean: @rm -rf go.mod @rm -rf go.sum @rm -rf vendor deps: @echo "初始化模块" go mod init wages_service @echo "下载依赖" export GOPROXY=http://goproxy.io go mod tidy -v @echo "检查依赖是否全部下载" go mod verify @echo "创建vendor" go mod vendor ``` ## 3 新建main.go文件 ``` package main import ( "github.com/gin-gonic/gin" "net/http" "time" ) func main() { r := gin.Default() r.GET("/test", func(c *gin.Context) { data := map[string]interface{}{ "lang": "golang", } c.AsciiJSON(http.StatusOK, data) }) s := &http.Server{ Addr: ":9000", Handler: r, ReadTimeout: 30 * time.Second, WriteTimeout: 30 * time.Second, MaxHeaderBytes: 1 << 20, } s.ListenAndServe() } ``` ## 4 执行命令 安装依赖包 ``` make all 初始化模块 go mod init wages_service go: creating new go.mod: module wages_service 初始化模块结束 下载依赖 export GOPROXY=http://goproxy.io go mod tidy go mod vendor 下载依赖结束 ``` ## 5 启动服务 ``` go run main.go [GIN-debug] [WARNING] Creating an Engine instance with the Logger and Recovery middleware already attached. [GIN-debug] [WARNING] Running in "debug" mode. Switch to "release" mode in production. - using env: export GIN_MODE=release - using code: gin.SetMode(gin.ReleaseMode) [GIN-debug] GET /test --> main.main.func1 (3 handlers) ``` ## 6 浏览器访问 `http://localhost:9000/test`
