问题描述
从一个来源我不能影响我在地图中给出的数据,它以 map [interface {}] interface {}
。
我需要处理包含的数据,最好是以 map [string] string
(内部的数据非常适合)。 >
我还需要从数据中生成密钥列表,因为这些不是事先知道的。
我可以在网上找到类似的问题或多或少地说,这是不可能的,但如果我的地图是 m
, fmt.Println(m)
显示数据,可读为 map [k0:v0 K1:v1 k2:v2 ...]
。
如何做fmt.Println能够做的事情?
也许我误会了这个问题,但这个工作吗?
m:= make(map [interface {}] interface {})
m [foo] =bar
m2:= make(map [string] string)
为键值:=范围m {
SW it键:= key。(type){
case string:
switch value:= value。(type){
case string:
m2 [key] = value
}
}
}
From a source I cannot influence I am given data in a map, which arrives as map[interface {}]interface {}
.
I need to process the contained data, preferably as map[string]string
(the data within is perfectly suitable for that).
I need to generate a list of the keys from the data as well, as those are not known beforehand.
Most similar questions I could find on the web say more or less, that this is impossible, but if my map is m
, fmt.Println(m)
shows the data is there, readable as map[k0:v0 K1:v1 k2:v2 ... ]
.
How can I do what fmt.Println is able to do?
Perhaps I misunderstand the question, but would this work?
m := make(map[interface{}]interface{})
m["foo"] = "bar"
m2 := make(map[string]string)
for key, value := range m {
switch key := key.(type) {
case string:
switch value := value.(type) {
case string:
m2[key] = value
}
}
}
