首先到
https://github.com/astaxie/beego/tree/master/plugins/cors
下載cros檔案
然後在main中引入cors包 在程式開始插入如下程式碼

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,
	}))
 

引數說明

AllowAllOrigins 允許全部來源設定為true則所有域名都可以訪問本網站介面，可以將此配置換成為AllowOrigins：[“允許訪問的域名”]
AllowMethods :允許的請求型別
AllowHeaders：允許的頭部資訊
ExposeHeaders：允許暴露的頭資訊
AllowCredentials：如果設定，允許共享AuthTuffic證書，如Cookie
