CORS headers middleware

[Oleg]

Right now all requests forbidden do to cors restriction, when using the beaver from the browser. Is it possible to add cors middleware that will add required headers to the requests? All needed data can be described in the config file.

For example, the middleware may be something like that:

func Cors(allowedMethods, allowedHeaders []string, allowedOriginPattern string) gin.HandlerFunc {
	return func(c *gin.Context) {
		r := c.Request
		w := c.Writer

		w.Header().Set("Content-Type", "application/json; charset=utf-8")
		w.Header().Set("Access-Control-Allow-Methods", strings.Join(allowedMethods, ", "))
		w.Header().Set("Access-Control-Allow-Headers", strings.Join(allowedHeaders, ", "))

		reqOrigin := r.Header.Get("Origin")

		switch allowedOriginPattern {
		case "*", ".*", "/*":
			w.Header().Set("Access-Control-Allow-Origin", "*")
		default:
			if ok, _ := regexp.MatchString(allowedOriginPattern, reqOrigin); ok {
				w.Header().Set("Access-Control-Allow-Origin", reqOrigin)
			}
		}

		if r.Method == "OPTIONS" {
			c.AbortWithStatus(http.StatusOK)
		} else {
			c.Next()
		}
	}
}

Or maybe better to use gin cors middleware.
