按索引jsonparser訪問字段

-2

我有問題通過索引訪問字段。這個庫https://github.com/buger/jsonparser 按索引jsonparser訪問字段

例如從https://github.com/buger/jsonparser：

// Or use can access fields by index! 
jsonparser.GetInt("person", "avatars", "[0]", "url")

我的代碼：

package main 

    import (
     "github.com/buger/jsonparser" 
     "fmt" 
    ) 
    func main() { 
     data := []byte(`{ 
     "person": { 
      "name": { 
      "first": "Leonid", 
      "last": "Bugaev", 
      "fullName": "Leonid Bugaev" 
      }, 
      "github": { 
      "handle": "buger", 
      "followers": 109 
      }, 
      "avatars": [ 
      { 
       "url": "https://avatars1.githubusercontent.com/u/14009?v=3&s=460", 
       "type": "thumbnail" 
      } 
      ] 
     }, 
     "company": { 
      "name": "Acme" 
     } 
     }`) 

     fmt.Println(jsonparser.GetInt(data, "person", "[2]", "[0]", "url")) 
    }

結果在終端： 0鑰匙未找到路徑
