Go nested map iteration
问题
我正在尝试迭代整个eventObj映射的键，包括其中的嵌套对象，并检查每个键和值以进行进一步的操作。
因此，如果我看到另一个嵌套映射，我也需要对其进行迭代。
我尝试使用类型比较map[string]interface{}或map[string]interface {}来实现，但似乎出现了语法错误。
我的问题是如何识别嵌套映射？
（请注意，我可能有多个嵌套映射）
func lookForEmailsInEvent(eventObj map[string]interface {}) {
for key, _ := range eventObj {
valueType := reflect.TypeOf(eventObj[key]).String()
fmt.Printf("%v : %v\n", key, valueType)
if valueType == "map[string]interface {}" {
lookForEmailsInEvent(eventObj[key].(map[string]interface {}))
} else if key == "email" {
// do something...
}
}
}
这是eventObj的值（从终端截图）：
英文:
I'm trying to iterate over the entire keys of a map eventObj, including the nested objects inside it and check every key and value for further actions.
So, if I see another nested map I will need to iterate it as well.
I've tried to do so with the comparison of the type to map[string]interface or map[string]interface{} but it seems to be a syntax error.
My question is how to identify a nested map?
(note that I can have several nested maps)
func lookForEmailsInEvent(eventObj map[string]interface {}) {
for key, _ := range eventObj {
valueType := reflect.TypeOf(eventObj[key]).String()
fmt.Printf("%v : %v\n", key, valueType)
if valueType == map[string]interface {
lookForEmailsInEvent(eventObj[key])
} else if key == "email" {
// do something...
}
}
}
This is the value of eventObj (screenshot from terminal):

以下是如何通过嵌套数据进行递归的方法：
func lookForEmailsInEvent(eventObj map[string]any) {
for k, v := range eventObj {
if v, ok := v.(map[string]any); ok {
lookForEmailsInEvent(v)
} else if k == "email" {
// 做一些操作
}
}
}
这段代码使用了 类型断言 来确定一个值是否为 map[string]any 类型。
英文:
Here's how to recurse through the nested data:
func lookForEmailsInEvent(eventObj map[string]any) {
for k, v := range eventObj {
if v, ok := v.(map[string]any); ok {
lookForEmailsInEvent(v)
} else if k == "email" {
// do something
}
}
}
This code uses a type assertion to determine if a value is a map[string]any.
