Gorilla jsonrpc getting empty response
问题
为什么我的jsonrpc方法返回一个空响应？
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 *Response) error {
reply.sum = args.A + args.B
reply.message = "Do math"
// 这种方式也不起作用
//*reply = Response{
// sum : 12,
// message : "Do math",
//}
return nil
}
请求：
{"method":"Arith.Add","params":[{"A": 10, "B":2}], "id": 1}
响应：
{
"result": {},
"error": null,
"id": 1
}
然而，如果我将reply的类型设置为*string，那么它将正常工作：
*reply = "Responding with strings works"
响应：
{
"result": "Responding with strings works",
"error": null,
"id": 1
}

Response:
{
"result": {},
"error": null,
"id": 1
}
However, if I set the type of reply to *string, then this will work fine:
*reply = "Responding with strings works"
Response:
{
"result": "Responding with strings works",
"error": null,
"id": 1
}

你的Response字段是不可导出的。名称应该是大写的：
type Response struct {
Sum int
Message string
}
英文:
Your Response fields are unexported. The names should be uppercase:
type Response struct {
Sum int
Message string
}
