func init() {
extension. SetFilter("myCustomFilter", NewMyClientFilter)
}
func NewMyClientFilter() filter. Filter {
return &MyClientFilter{}
}
type MyClientFilter struct {
}
func (f *MyClientFilter) Invoke(ctx context.Context, invoker protocol.Invoker, invocation protocol.Invocation) protocol.Result {
fmt.Println("MyClientFilter Invoke is called, method Name = ", invocation.MethodName())
return invoker. Invoke(ctx, invocation)
}
func (f *MyClientFilter) OnResponse(ctx context.Context, result protocol.Result, invoker protocol.Invoker, protocol protocol.Invocation) protocol.Result {
fmt.Println("MyClientFilter OnResponse is called")
return result
}
