# Client/Server
|
|
|
|
Go Micro uses a client/server model for RPC communication between services.
|
|
|
|
## Client
|
|
The client is used to make requests to other services.
|
|
|
|
## Server
|
|
The server handles incoming requests.
|
|
|
|
Both client and server are pluggable and support middleware wrappers for additional functionality.
|
|
|
|
## Example Usage
|
|
|
|
Here's how to define a simple handler and register it with a Go Micro server:
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"context"
|
|
"go-micro.dev/v6"
|
|
"log"
|
|
)
|
|
|
|
type Greeter struct{}
|
|
|
|
func (g *Greeter) Hello(ctx context.Context, req *struct{}, rsp *struct{Msg string}) error {
|
|
rsp.Msg = "Hello, world!"
|
|
return nil
|
|
}
|
|
|
|
func main() {
|
|
service := micro.NewService("greeter",
|
|
)
|
|
service.Init()
|
|
micro.RegisterHandler(service.Server(), new(Greeter))
|
|
if err := service.Run(); err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
}
|
|
```
