Go gin framework CORS
FWIW, this is my CORS Middleware that works for my needs. 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() } }
