Question

mgo （mongodb go）如何进行类似shell 的save 或者c#驱动的replace操作？

Answer 1

I have solved it myself

See [httpmongo]https://github.com/golangframework/httpmongo/blob/master/collection.go for details

Mongodb provides a method of complete replacement based on _id
I used the method of remove first, then insert to implement the save operation, which also ensures that data that meets the filter conditions will not be repeated multiple times.
