Go gin framework CORS

Question

I\'m using Go gin framework gin

func CORSMiddleware() gin.HandlerFunc {
    return func(c *gin.Context) {
        c.Writer.Header().Set(\"Content-Type\", \"a         


        

Answer 1

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()
    }
}

then use it

router = gin.New()  
router.Use(CORSMiddleware())
