在 2.2 版更改: In previous versions ObjectId.toString() returns the value of the ObjectId as a hexadecimal string.
In the following example, call the toString() method on an ObjectId (e.g. ObjectId("507c7f79bcf86cd7994f6c0e")), as follows:
ObjectId("507c7f79bcf86cd7994f6c0e").toString()
This will return the following string:
ObjectId("507c7f79bcf86cd7994f6c0e")
You can confirm the type of this object using the following operation:
typeof ObjectId("507c7f79bcf86cd7994f6c0e").toString()
