为什么我的jsonrpc方法返回空响应？ type Args struct {
A, B int
}
type Response struct {
sum int
message string
}
type Arith int
func (t *Arith) Add(r *http.Request, args *Args, reply *Respons
当我启动我的程序： import bitcoinrpc
import csv
# docs at https://github.com/massanchik/bitcoin-python3
# docs at https://docs.python.org/3.3/library/csv.html
user = 'user'
password = 'password'
port
