# Hello Service
|
|
|
|
A minimal HTTP service using Go Micro, with a single endpoint.
|
|
|
|
## Service
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"context"
|
|
"go-micro.dev/v6"
|
|
)
|
|
|
|
type Request struct { Name string `json:"name"` }
|
|
|
|
type Response struct { Message string `json:"message"` }
|
|
|
|
type Say struct{}
|
|
|
|
func (h *Say) Hello(ctx context.Context, req *Request, rsp *Response) error {
|
|
rsp.Message = "Hello " + req.Name
|
|
return nil
|
|
}
|
|
|
|
func main() {
|
|
svc := micro.NewService("helloworld")
|
|
svc.Init()
|
|
svc.Handle(new(Say))
|
|
svc.Run()
|
|
}
|
|
```
|
|
|
|
Run it:
|
|
|
|
```bash
|
|
go run main.go
|
|
```
|
|
|
|
Call it:
|
|
|
|
```bash
|
|
curl -XPOST \
|
|
-H 'Content-Type: application/json' \
|
|
-H 'Micro-Endpoint: Say.Hello' \
|
|
-d '{"name": "Alice"}' \
|
|
http://127.0.0.1:8080
|
|
```
|
|
|
|
Set a fixed address:
|
|
|
|
```go
|
|
svc := micro.NewService("helloworld",
|
|
micro.Address(":8080"),
|
|
)
|
|
```
