Function GetReqHeader

req.go:480–486

GetReqHeader returns the HTTP request header specified by filed. This function is generic and can handle different headers type values. If the generic type cannot be matched to a supported type, the function returns the default value (if provided) or the zero value of type V.

(c Ctx, key string, defaultValue ...V)

// If the generic type cannot be matched to a supported type, the function
// returns the default value (if provided) or the zero value of type V.
func GetReqHeader[V GenericType](c Ctx, key string, defaultValue ...V) V {
	v, err := genericParseType[V](c.App().toString(c.Request().Header.Peek(key)))
	if err != nil && len(defaultValue) > 0 {
		return defaultValue[0]
	}
	return v
}

// GetHeaders (a.k.a GetReqHeaders) returns the HTTP request headers.
// Returned value is only valid within the handler. Do not store any references.
