英文:
Unable to unmarshal number into Go Value
问题
我尝试避免问一些简单答案的问题，但我似乎无法弄清楚问题出在哪里...（标题中的问题）
相关代码：
match := new(Match)
if _, msgB, err = ws.ReadMessage(); err != nil {
panic(err)
} else {
println(string(msgB))
err = json.Unmarshal(msgB, match)
if err != nil { panic(err) }
}
type Match struct {
Teams [][]Char
Map [][]Tile
ID string //uuid
Socket *websocket.Conn `json:'-'`
}
type Char struct {
ID int
HP int
CT int
Stats statList
X int
Y int
ACList Actions
}
type statList struct {
Str int
Vit int
Int int
Wis int
Dex int
Spd int
}
type Actions struct {
Actions []Action
TICKCT int
}
要解组的字符串（为了可见性进行格式化）：
{
"Teams": [
[
{
"ID": 1,
"HP": 10,
"CT": 0,
"Stats": [
1,

I try to refrain from asking questions with simple answers but I can't seem to figure out what the issue is here... (Issue in title)
Relevant code:
match := new(Match)
if _, msgB, err = ws.ReadMessage(); err != nil {
panic(err)
}else {
println(string(msgB))
err = json.Unmarshal(msgB, match)
if err != nil { panic(err) }

我修改了代码的固定版本（playground）。这似乎是主要的错误：
type Char struct {
ID int
HP int
CT int
Stats []int // 这里是 statList，这样是行不通的
X int
Y int
ACList Actions
}
另外请注意我对 Tile 的定义，允许数字为 nil。
type Tile struct {
Depth int
Type int
Unit *int
}
你没有提供所有的结构，所以我自己编写了一些——可能是错误的！总的来说，代码如下：
import (
"encoding/json"
"fmt"
)
type Match struct {
Teams [][]Char
Map [][]Tile
ID string //uuid
// Socket *websocket.Conn `json:'-'`
}
type Char struct {
ID int
HP int
CT int
Stats []int // 这里是 statList，这样是行不通的
X int
Y int
ACList Actions
}
type statList struct {
Str int
Vit int
Int int
Wis int
Dex int
Spd int
}
type Action string
type Actions struct {
Actions []Action
TICKCT int
}
type Tile struct {
Depth int
Type int
Unit *int
}
var data = `{

I made a fixed version of the code (playground). This seemed to be the main mistake:
type Char struct {
ID int
HP int
CT int
Stats []int // This was statList which won't work
X int
Y int
ACList Actions
}
Also note the definition I made of Tile which allows numbers to be nil.
type Tile struct {
Depth int
Type int
Unit *int
}
You didn't provide all the structures so I made some up - probably wrong! All together that is:
import (
"encoding/json"
"fmt"
)
type Match struct {
Teams [][]Char
Map [][]Tile
ID string //uuid
// Socket *websocket.Conn `json:'-'`
}
type Char struct {
ID int
HP int
CT int
Stats []int // This was statList which won't work
X int
Y int
ACList Actions
}
type statList struct {
Str int
Vit int
Int int
Wis int
Dex int
Spd int
}
type Action string
type Actions struct {
Actions []Action
TICKCT int
}
type Tile struct {
Depth int
Type int
Unit *int
}
var data = `{
