conf>app.conf 文件添加一下參數

copyrequestbody=true
sessionon =true

routers>router.go 文件添加初始化路由

func init() {
    
    ///api/v1.0/areas
    // beego.Router("/api/v1.0/areas", &controllers.AreaController{},"get:GetArea")
    beego.Router("api/v1.0/areas", &controllers.LAreaControllers{}, "get:GetArea")
    //TODO /api/v1.0/session
    //TODO /api/v1.0/houses/index
    beego.Router("/api/v1.0/session",&controllers.SessionController{},"get:GetSessionData;delete:DeleteSessionData")

main.go beego前后端分離靜態頁面承載有點費勁，不過也好只是比gin多幾句代碼而已

package main

import (
    _ "lovehome/routers"
    _ "lovehome/models"
    "github.com/astaxie/beego"

    "github.com/astaxie/beego/context"
    "net/http"
    "strings"
)

func main() {
    ignoreStaticPath()
    beego.Run()
}

func ignoreStaticPath()  {
    beego.InsertFilter("/",beego.BeforeRouter,TransparentStatic)
    beego.InsertFilter("/*",beego.BeforeRouter,TransparentStatic)
}

func TransparentStatic(ctx *context.Context){
    orpath := ctx.Request.URL.Path
    beego.Info("request url:",orpath)
    //如果請求url包含api字段，說明指令應該取消靜態資源重定向
    if strings.Index(orpath,"api") >= 0{
        return
    }


    http.ServeFile(ctx.ResponseWriter,ctx.Request,"static/html/"+ctx.Request.URL.Path)

}
