question: how to use github.com/go-playground/validator to validate the request

[westwin]

I'm thinking if there's a way to write a server plugin to validate the request ?
looks like server PreCall plugin can do this.

but what if with the use of AddHandler() ?

thanks

and btw, in https://github.com/smallnest/rpcx/blob/master/client/xclient.go, line 889
c.Plugins.DoPreCall(ctx, c.servicePath, serviceMethod, args)

what if the DoPreCall() returns an error ?
