##Golang JSON-RPC Server example
####SMS Args
type SmsArgs struct {
Number, Content string
}####Email Args
type EmailArgs struct {
To, Subject, Content string
}####Response structure for email and SMS service
type Response struct {
Result string
}####Simple example of SMS service without logic
type SmsService struct{}
func (t *SmsService) SendSMS(r *http.Request, args *SmsArgs, result *Response) error {
*result = Response{Result: fmt.Sprintf("Sms sent to %s", args.Number)}
return nil
}####Simple example of Email service without logic
type EmailService struct{}
func (t *EmailService) SendEmail(r *http.Request, args *EmailArgs, result *Response) error {
*result = Response{Result: fmt.Sprintf("Email sent to %s", args.To)}
return nil
}####Example how to register services and start rpc server
func main() {
rpcServer := rpc.NewServer()
rpcServer.RegisterCodec(json.NewCodec(), "application/json")
rpcServer.RegisterCodec(json.NewCodec(), "application/json;charset=UTF-8")
sms := new(SmsService)
email := new(EmailService)
rpcServer.RegisterService(sms, "sms")
rpcServer.RegisterService(email, "email")
router := mux.NewRouter()
router.Handle("/delivery", rpcServer)
http.ListenAndServe(":1337", router)
}####Example how to use JSON-RPC server written in Go with JSON-RPC client written in python
import json
import requests
def rpc_call(url, method, args):
headers = {'content-type': 'application/json'}
payload = {
"method": method,
"params": [args],
"jsonrpc": "2.0",
"id": 1,
}
response = requests.post(url, data=json.dumps(payload), headers=headers).json()
return response['result']
url = 'http://localhost:1337/delivery'
emailArgs = {'To': 'demo@example.com','Subject': 'Hello', 'Content': 'Hi!!!'}
smsArgs = {'Number': '381641234567', 'Content': 'Sms!!!'}
print rpc_call(url, 'email.SendEmail', emailArgs)
print rpc_call(url, 'sms.SendSMS', smsArgs)
