Through a series of debugging, we found that the provder did not resolve to
attchments (the reason should be that the client did not pass the relevant
parameters), so i gave an initialized value:
(dubbo-go/protocol/dubbo/impl/hessian.go
```
attachments, err := decoder.Decode()
...
if attachments == nil {
attachments = map[interface{}]interface{}{"interface": target}
}
```
ps: the above code is only a preliminary judgment and ultimately needs to be
discussed with the developers.
