BUG

Describe the bug panic: interface conversion on function GetStringAttribute / GetIntAttribute can't read null memory

To Reproduce

Check kws.attributes map variable before return interface conversion.

func (kws *Websocket) GetIntAttribute(key string) int { kws.mu.RLock() defer kws.mu.RUnlock() val, ok := kws.attributes[key] if !ok || val == nil { return 0 } return val.(int) }

func (kws *Websocket) GetStringAttribute(key string) string { kws.mu.RLock() defer kws.mu.RUnlock() val, ok := kws.attributes[key] if !ok || val == nil { return "" } return val.(string) }
