从过去 2 天开始,我不知怎么地就被 JSON 和 Go 困住了。我的目标非常简单,一个 Go 程序可以读取 JSON 文件,正确输出它并向该 JSON 添加一些项目,然后将其重写回磁盘。保存的 JSON 文件。{"Category": ["food","music"],"Time(min)": "351","Channel": { "d2d": 10, "mkbhd": 8, "coding Train": 24},"Info": { "Date":{ "date":["vid_id1","vid_id2","vid_id3"], "02/11/2019":["id1","id2","id3"], "03/11/2019":["SonwZ6MF5BE","8mP5xOg7ijs","sc2ysHjSaXU"] }, "Videos":{ "videos": ["Title","Category","Channel","length"], "sc2ysHjSaXU":["Bob Marley - as melhores - so saudade","Music","So Saudade","82"], "SonwZ6MF5BE":["Golang REST API With Mux","Science & Technology","Traversy Media","44"], "8mP5xOg7ijs":["Top 15 Funniest Friends Moments","Entertainment","DjLj11","61"] } }}我已经在 Go 中成功解析了 JSON,但是当我尝试获取 JSON["Info"]["Date"] 时,它会抛出接口错误。我无法创建特定的结构,因为每当调用代码/API 时,所有项目都会动态更改。我用来解析数据的代码// Open our jsonFilejsonFile, err := os.Open("yt.json")if err != nil {fmt.Println(err)}fmt.Println("Successfully Opened yt.json")defer jsonFile.Close()byteValue, _ := ioutil.ReadAll(jsonFile)var result map[string]interface{}json.Unmarshal([]byte(byteValue), &result)json_data := result["Category"] //returns correct ansjson_data := result["Info"]["Date"] // returns error - type interface {} does not support indexing任何帮助/领导都将受到高度赞赏。非常感谢。json去编组解组

您无法使用 访问内部属性result[][]。你需要做如下的事情,
info:= result["Info"]
v := info.(map[string]interface{})
json_data = v["Date"]
