Cannot unmarshal string into Go value of type int64

Question

I have struct

type tySurvey struct {
    Id     int64            `json:\"id,omitempty\"`
    Name   string           `json:\"name,omitempty\"`
}

<

Answer 1

use json.Number

type tySurvey struct {
    Id     json.Number      `json:"id,omitempty"`
    Name   string           `json:"name,omitempty"`
}

Answer 2

This is handled by adding ,string to your tag as follows:

type tySurvey struct {
   Id   int64  `json:"id,string,omitempty"`
   Name string `json:"name,omitempty"`
}

This can be found about halfway through the documentation for Marshal.

Please note that you cannot decode the empty string by specifying omitempty as it is only used when encoding.
