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：

  1. match := new(Match)
  2. if _, msgB, err = ws.ReadMessage(); err != nil {
  3.     panic(err)
  4. } else {
  5.     println(string(msgB))
  6.     err = json.Unmarshal(msgB, match)
  7.     
  8.     if err != nil { panic(err) }
  9. }
  12. type Match struct {
  13.     Teams [][]Char
  14.     Map [][]Tile
  15.     ID string //uuid
  16.     Socket *websocket.Conn `json:'-'`
  17. }
  18. type Char struct {
  19.     ID int
  20.     HP int
  21.     CT int
  22.     Stats statList 
  23.     X int
  24.     Y int
  25.     ACList Actions
  26. }
  27. type statList struct {
  28.     Str int
  29.     Vit int
  30.     Int int
  31.     Wis int
  32.     Dex int
  33.     Spd int
  34. }
  35. type Actions struct {
  36.     Actions []Action
  37.     TICKCT int
  38. }

要解组的字符串（为了可见性进行格式化）：

得分: 1

我修改了代码的固定版本（playground）。这似乎是主要的错误：

  1. type Char struct {
  2.     ID     int
  3.     HP     int
  4.     CT     int
  5.     Stats  []int // 这里是 statList，这样是行不通的
  6.     X      int
  7.     Y      int
  8.     ACList Actions
  9. }

另外请注意我对 Tile 的定义，允许数字为 nil。

  1. type Tile struct {
  2.     Depth int
  3.     Type  int
  4.     Unit  *int
  5. }

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：

  1. import (
  2.     "encoding/json"
  3.     "fmt"
  4. )
  6. type Match struct {
  7.     Teams [][]Char
  8.     Map   [][]Tile
  9.     ID    string //uuid
  10.     //    Socket *websocket.Conn `json:'-'`
  11. }
  13. type Char struct {
  14.     ID     int
  15.     HP     int
  16.     CT     int
  17.     Stats  []int // 这里是 statList，这样是行不通的
  18.     X      int
  19.     Y      int
  20.     ACList Actions

I made a fixed version of the code (playground). This seemed to be the main mistake:

  1. type Char struct {
  2. ID     int
  3. HP     int
  4. CT     int
  5. Stats  []int // This was statList which won't work
  6. X      int
  7. Y      int
  8. ACList Actions
  9. }

Also note the definition I made of Tile which allows numbers to be nil.

  1. type Tile struct {
  2. Depth int
  3. Type  int
  4. Unit  *int
  5. }

You didn't provide all the structures so I made some up - probably wrong! All together that is:

  1. import (
  2. "encoding/json"
  3. "fmt"
  4. )
  5. type Match struct {
  6. Teams [][]Char
  7. Map   [][]Tile
  8. ID    string //uuid
  9. //    Socket *websocket.Conn `json:'-'`
  10. }
  11. type Char struct {
  12. ID     int
  13. HP     int
  14. CT     int
  15. Stats  []int // This was statList which won't work
  16. X      int
  17. Y      int
  18. ACList Actions
  19. }
  20. type statList struct {
  21. Str int
  22. Vit int
  23. Int int
  24. Wis int
  25. Dex int
  26. Spd int
  27. }
  28. type Action string
  29. type Actions struct {
  30. Actions []Action
