Golang如何通过反射检查结构体嵌套字段

func inspectStruct(v interface{}) {
    rv := reflect.ValueOf(v)
    if rv.Kind() == reflect.Ptr {
        rv = rv.Elem() // 解引用指针
    }
    if rv.Kind() != reflect.Struct {
        return
    }
<pre class="brush:php;toolbar:false;"><pre class="brush:php;toolbar:false;">t := rv.Type()
for i := 0; i < t.NumField(); i++ {
    field := t.Field(i)
    value := rv.Field(i)

    fmt.Printf("字段名: %s, 类型: %s\n", field.Name, field.Type)

    if field.Anonymous {
        fmt.Println("  → 是匿名字段")
    }

    // 检查是否为结构体或结构体指针
    fieldType := field.Type
    if fieldType.Kind() == reflect.Ptr {
        fieldType = fieldType.Elem()
    }

    if fieldType.Kind() == reflect.Struct {
        fmt.Printf("  → 嵌套结构体: %s\n", fieldType.Name())
        // 递归检查嵌套结构体
        nestedVal := value
        if nestedVal.Kind() == reflect.Ptr && !nestedVal.IsNil() {
            nestedVal = nestedVal.Elem()
        }
        if nestedVal.Kind() == reflect.Struct {
            inspectStruct(nestedVal.Interface())
        }
    }
}

if tag := field.Tag.Get("json"); tag != "" {
    fmt.Printf("  标签 json: %s\n", tag)
}
