Beego框架解决'Access-Control-Allow-Origin'跨域问题

配置方法如下:

package main

import (
	beego "github.com/beego/beego/v2/server/web"
	"github.com/beego/beego/v2/server/web/filter/cors"
)

func main() {

	// 解决跨域问题
	beego.InsertFilter("/*", beego.BeforeRouter, cors.Allow(&cors.Options{
		AllowAllOrigins:  true,
		AllowMethods:     []string{"GET", "POST", "PUT", "DELETE", "OPTIONS"},
		AllowHeaders:     []string{"Origin", "Authorization", "Access-Control-Allow-Origin", "Access-Control-Allow-Headers", "Content-Type"},
		ExposeHeaders:    []string{"Content-Length", "Access-Control-Allow-Origin", "Access-Control-Allow-Headers", "Content-Type"},
		AllowCredentials: true,
	}))

	beego.Run()
}
