Golang-无法将数字解组为字符串类型的Go值

Question

When trying to json.Unmarshal some JSON code from a website into a struct I created, I receive the following error:

cannot unmarshal number into Go value of type string

Here is my code: https://play.golang.org/p/-5nphV9vPw

this works for me (corrected version):

package main

import (
    "encoding/json"
    "fmt"
    "log"
)
