}С помощью Gin
func Options() gin.HandlerFunc {
return func(ctx *gin.Context) {
if ctx.Request.Method != "OPTIONS" {
ctx.Next()
} else {
ctx.Header("Access-Control-Allow-Origin", "*")
ctx.Header("Access-Control-Allow-Methods", "GET,POST,PUT,PATCH,DELETE,OPTIONS")
ctx.Header("Access-Control-Allow-Headers", "authorization, origin, content-type, accept")
ctx.Header("Allow", "HEAD,GET,POST,PUT,PATCH,DELETE,OPTIONS")
ctx.Header("Content-Type", "application/json")
ctx.AbortWithStatus(200)
}
}
}Или например отключить кэш
func NoCache() gin.HandlerFunc {
return func(ctx *gin.Context) {
ctx.Header("Cache-Control", "no-cache, no-store, max-age=0, must-revalidate, value")
ctx.Header("Expires", "Thu, 01 Jan 1970 00:00:00 GMT")
ctx.Header("Last-Modified", time.Now().UTC().Format(http.TimeFormat))
ctx.Next()
}
}
