Go gin框架CORS
Go gin框架CORS
提问于 2015-04-02 17:03:17
我正在使用gin框架杜松子酒
func CORSMiddleware() gin.HandlerFunc {
return func(c *gin.Context) {
c.Writer.Header().Set("Content-Type", "application/json")
c.Writer.Header().Set("Access-Control-Allow-Origin", "*")
c.Writer.Header().Set("Access-Control-Max-Age", "86400")
c.Writer.Header().Set("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, DELETE, UPDATE")
c.Writer.Header().Set("Access-Control-Allow-Headers", "Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token, Authorization, X-Max")
c.Writer.Header().Set("Access-Control-Allow-Credentials", "true")
if c.Request.Method == "OPTIONS" {
c.AbortWithStatus(200)
} else {
c.Next()
}
}
}我有状态代码:200 OK，但是在选项请求之后什么都不会发生。看上去我好像错过了什么，但我不知道我哪里错了。
有人能帮我吗？

FWIW，这是我的CORS中间件，可以满足我的需要。
func CORSMiddleware() gin.HandlerFunc {
return func(c *gin.Context) {
c.Writer.Header().Set("Access-Control-Allow-Origin", "*")
c.Writer.Header().Set("Access-Control-Allow-Credentials", "true")
c.Writer.Header().Set("Access-Control-Allow-Headers", "Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token, Authorization, accept, origin, Cache-Control, X-Requested-With")
c.Writer.Header().Set("Access-Control-Allow-Methods", "POST, OPTIONS, GET, PUT")
if c.Request.Method == "OPTIONS" {
c.AbortWithStatus(204)
return
}
c.Next()
}

还有官方的gin中间件来处理CORS请求Github.com/gin-cont肋骨/cors。
您可以使用$ go get github.com/gin-contrib/cors安装它，然后在应用程序中添加以下中间件: package
import (
"time"
"github.com/gin-contrib/cors"
"github.com/gin-gonic/gin"
)
func main() {
router := gin.Default()
// CORS for https://foo.com and https://github.com origins, allowing:
// - PUT and PATCH methods
// - Origin header
// - Credentials share
// - Preflight requests cached for 12 hours
router.Use(cors.New(cors.Config{
AllowOrigins: []string{"https://foo.com"},
AllowMethods: []string{"PUT", "PATCH"},
AllowHeaders: []string{"Origin"},
ExposeHeaders: []string{"Content-Length"},
AllowCredentials: true,
AllowOriginFunc: func(origin string) bool {
return origin == "https://github.com"
},
MaxAge: 12 * time.Hour,
}))
router.Run()

func CORSMiddleware() gin.HandlerFunc {
return func(c *gin.Context) {
c.Header("Access-Control-Allow-Origin", "*")
c.Header("Access-Control-Allow-Credentials", "true")
c.Header("Access-Control-Allow-Headers", "Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token, Authorization, accept, origin, Cache-Control, X-Requested-With")
c.Header("Access-Control-Allow-Methods", "POST,HEAD,PATCH, OPTIONS, GET, PUT")
if c.Request.Method == "OPTIONS" {
c.AbortWithStatus(204)
return
}
c.Next()
}
}那就用它
router = gin.New()
