# How To
|
|
|
|
|
|
|
|
Define some types and routes:
|
|
|
|
|
|
|
|
```
|
|
|
|
// Define a type for results and register concrete versions with go-wire
|
|
|
|
type Result interface{}
|
|
|
|
|
|
|
|
type ResultStatus struct {
|
|
|
|
Value string
|
|
|
|
}
|
|
|
|
|
|
|
|
var _ = wire.RegisterInterface(
|
|
|
|
struct{ Result }{},
|
|
|
|
wire.ConcreteType{&ResultStatus{}, 0x1},
|
|
|
|
)
|
|
|
|
|
|
|
|
// Define some routes
|
|
|
|
var Routes = map[string]*rpcserver.RPCFunc{
|
|
|
|
"status": rpcserver.NewRPCFunc(StatusResult, "arg"),
|
|
|
|
}
|
|
|
|
|
|
|
|
// an rpc function
|
|
|
|
func StatusResult(v string) (Result, error) {
|
|
|
|
return &ResultStatus{v}, nil
|
|
|
|
}
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
Now start the server:
|
|
|
|
|
|
|
|
```
|
|
|
|
mux := http.NewServeMux()
|
|
|
|
rpcserver.RegisterRPCFuncs(mux, Routes)
|
|
|
|
wm := rpcserver.NewWebsocketManager(Routes, nil)
|
|
|
|
mux.HandleFunc("/websocket", wm.WebsocketHandler)
|
|
|
|
go func() {
|
|
|
|
_, err := rpcserver.StartHTTPServer("0.0.0.0:46657", mux)
|
|
|
|
if err != nil {
|
|
|
|
panic(err)
|
|
|
|
}
|
|
|
|
}()
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
Note that unix sockets are supported as well (eg. `/path/to/socket` instead of `0.0.0.0:46657`)
|
|
|
|
|
|
|
|
Now see all available endpoints by sending a GET request to `0.0.0.0:46657`.
|
|
|
|
Each route is available as a GET request, as a JSONRPCv2 POST request, and via JSONRPCv2 over websockets
