Hand in hand, take you to use the Beego Mall series three (system configuration)

Full project address: Go-shop-B2C

preface

This article will explain some basic configuration to start the project, such as through the bee tool to generate model layer, CORS configuration, router configuration, log configuration and so on

The Bee tool generates the Model layer

Bee Tool Introduction

Bee tool is a project created to assist in rapid development of Beego projects. Through Bee, you can easily create, heat compile, develop, test, and deploy Beego projects.

Bee tool installation

go get -u github.com/beego/bee/v2
Copy the code

The input

bee version
Copy the code

As shown below:

This section only describes bee reverse generation of API applications based on MySql

API command

Bee API [appname] [-tables=""] [-driver=mysql] [-conn="root:<password>@tcp(127.0.0.1:3306)/test"]Copy the code

Description of optional commands

• Appname, the name of the generated API application
• -tables: indicates the generated table name. “” reflects all tables. If a fixed table name is entered, only the entered table name is reflected
• – Driver Indicates a database driver that supports Mysql, Oracle, and Mongodb
• -conn, connection address, root:@tcp(127.0.0.1:3306)/test

Enter the following command:

Bee API appname-tables ="" -driver= mysql-conn ="root:123456@tcp(127.0.0.1:3306)/go-shop-b2c"Copy the code

The directory structure is as follows:

Project Routing Settings

We’ve created the BeeGo project and we’ve seen it up and running, so how does it work? Let’s start with the import file:

package main

import(_"quickstart/routers"
    "github.com/beego/beego/v2/server/web"
)

func main(a) {
    web.Run()
}
Copy the code

We see that main is the entry function, but we know that Go is executed in the following way:

The quickstart/routers package has been added to the interface, and the init function has been added to the interface.

package routers

import (
	"appname/controllers"

	beego "github.com/beego/beego/v2/server/web"
)

func init(a) {
    ns := beego.NewNamespace("/v1",
    
        beego.NSNamespace("/ad",
            beego.NSInclude(
                &controllers.AdController{},
            ),
        ),
    )
	beego.AddNamespace(ns)
}
Copy the code

CORS configuration

API projects typically require cross-domain configuration to facilitate front-end local debugging, as follows:

func corsInit(a) {
	beego.InsertFilter("*", beego.BeforeRouter, cors.Allow(&cors.Options{
		/ / optional parameters "GET", "POST", "PUT", "DELETE", "OPTIONS" (*) for all
		// where Options cross-domain complex request precheck
		AllowMethods: []string{"GET"."POST"."PUT"."DELETE"."OPTIONS"},
		// Specifies the types of headers allowed
		AllowHeaders: []string{"Origin"."Authorization"."Access-Control-Allow-Origin"."Access-Control-Allow-Headers"."Content-Type"},
		// A list of exposed HTTP headers
		ExposeHeaders: []string{"Content-Length"."Access-Control-Allow-Origin"."Access-Control-Allow-Headers"."Content-Type"},
		// If set, authentication credentials such as cookies are allowed to be shared
		AllowCredentials: true.// Specify the accessible domain name AllowOrigins
		AllowOrigins: []string{"*"}}}))Copy the code

The log configuration

_ = logs.SetLogger("console")
logs.EnableFuncCallDepth(true)
