在golang中，解析json是一項非常常見的任務。而當需要解析的json中有多維嵌套數據時，該如何進行解析呢？本文將介紹如何使用golang解析多維json。

首先，定義一個用于解析json的結構體。結構體中的字段名稱必須與json中的key名稱保持一致：

type person struct {
Name    string   `json:"name"`
Gender  string   `json:"gender"`
Age     int      `json:"age"`
Hobbies []string `json:"hobbies"`
}
type company struct {
Name     string   `json:"name"`
Location string   `json:"location"`
Employees []person `json:"employees"`
}

假設我們有如下的json數據：

{
"name": "Google",
"location": "Mountain View, CA",
"employees": [
{
"name": "John Doe",
"gender": "male",
"age": 30,
"hobbies": ["reading", "jogging"]
},
{
"name": "Jane Smith",
"gender": "female",
"age": 25,
"hobbies": ["swimming", "painting", "hiking"]
}
]
}

那么我們可以使用如下代碼進行解析：

jsonData := `{"name": "Google","location": "Mountain View, CA","employees": [{"name": "John Doe","gender": "male","age": 30,"hobbies": ["reading", "jogging"]},{"name": "Jane Smith","gender": "female","age": 25,"hobbies": ["swimming", "painting", "hiking"]}]}`
var c company
err := json.Unmarshal([]byte(jsonData), &c)
if err != nil {
panic(err)
}
fmt.Printf("Company name: %s\n", c.Name)
fmt.Printf("Location: %s\n", c.Location)
for _, e := range c.Employees {
fmt.Printf("Employee name: %s\n", e.Name)
fmt.Printf("Gender: %s\n", e.Gender)
fmt.Printf("Age: %d\n", e.Age)
fmt.Printf("Hobbies: %v\n\n", e.Hobbies)
}

運行上述代碼將會輸出如下結果：

Company name: Google
Location: Mountain View, CA
Employee name: John Doe
Gender: male
Age: 30
Hobbies: [reading jogging]
Employee name: Jane Smith
Gender: female
Age: 25
Hobbies: [swimming painting hiking]

如此便完成了golang解析多維json的操作。
