Golang - convert array / map to JSON
问题
我正在尝试将一个map[]转换为JSON，以便我可以将其作为请求的一部分进行提交。但是我的map[]包含了不同的类型，包括字符串和整数。
我目前的代码如下：
mapD := map[string]string{"deploy_status": "public", "status": "live", "version": 2}
mapB, _ := json.Marshal(mapD)
fmt.Println(string(mapB))
//输出结果
prog.go:17: cannot use 2 (type int) as type string in map value
请问如何使得我可以在同一个map中包含字符串和整数呢？
谢谢。

I am trying to convert a map[] to JSON so I can post it as part of a request. But my map[] has various types including strings / ints.
I currently have:
mapD := map[string]string{"deploy_status": "public", "status": "live", "version": 2}
mapB, _ := json.Marshal(mapD)
fmt.Println(string(mapB))
//output
prog.go:17: cannot use 2 (type int) as type string in map value
How do I make it so that I can include strings and ints within the same map?
Thanks

使用map[string]interface{}：
mapD := map[string]interface{}{"deploy_status": "public", "status": "live", "version": 2}
英文:
Use map[string]interface{} :
mapD := map[string]interface{}{"deploy_status": "public", "status": "live", "version": 2}

你正在尝试将一个类型为int的值用作字符串，但是你的映射被定义为[string]string。你需要将第一行修改为：
mapD := map[string]string{"deploy_status": "public", "status": "live", "version": "2"}
如果你不知道值的类型，可以使用interface{}代替。
英文:
You are trying to use a value of type int as a string, but your map is defined as [string]string. You have to modify the first line as:
mapD := map[string]string{"deploy_status": "public", "status": "live", "version": "2"}
If you do not know the type of the values, you can use interface{} instead.
