本文小编为大家详细介绍“Golanggin跨域问题怎么解决”，内容详细，步骤清晰，细节处理妥当，希望这篇“Golanggin跨域问题怎么解决”文章能帮助大家解决疑惑，下面跟着小编的思路慢慢深入，一起来学习新知识吧。
gin跨域解决方案
cors1.go
packagemiddlewaresimport("github.com/gin-gonic/gin""net/http")funcCors()gin.HandlerFunc{returnfunc(c*gin.Context){method:=c.Request.Methodorigin:=c.Request.Header.Get("Origin")iforigin!=""{c.Header("Access-Control-Allow-Origin",origin)//主要设置Access-Control-Allow-Originc.Header("Access-Control-Allow-Methods","POST,GET,OPTIONS,PUT,DELETE,UPDATE")c.Header("Access-Control-Allow-Headers","Origin,X-Requested-With,Content-Type,Accept,Authorization")c.Header("Access-Control-Expose-Headers","Content-Length,Access-Control-Allow-Origin,Access-Control-Allow-Headers,Cache-Control,Content-Language,Content-Type")c.Header("Access-Control-Allow-Credentials","false")c.Set("content-type","application/json")}ifmethod=="OPTIONS"{c.AbortWithStatus(http.StatusNoContent)}c.Next()}}
cors2.go
funcCors()gin.HandlerFunc{returncors.New(cors.Config{AllowAllOrigins:false,AllowOrigins:nil,AllowOriginFunc:func(originstring)bool{returntrue},AllowMethods:[]string{"GET","POST","PUT","PATCH","DELETE","HEAD"},AllowHeaders:[]string{"Authorization","ts","Accept","Origin","DNT","X-CustomHeader","Keep-Alive","User-Agent","X-Requested-With","If-Modified-Since","Cache-Control","Content-Type","Content-Range","Range"},AllowCredentials:true,MaxAge:10*time.Minute,})}
使用中间件
packagerouterimport("github.com/gin-gonic/gin""goproejct/controllers""goproejct/middlewares"//引入中间件goproject是项目名根据自己情况)funcInitRouter(){router:=gin.Default()router.Use(Cors())//使用中间件v1:=router.Group("v1"){v1.POST("/login",controllers.Login)v1.POST("/regist",controllers.Regist)}router.Run(":8000")}
