如何删除mongodb中的多个ID？

Answer 1

通过为每个ID运行一次remove,或者使用in:

db.collection.remove( { _id : { $in: [
    ObjectId("51ee3966e4b056fe8f074f48"), 
    ObjectId("51ee3966e4b056fe8f074f4a"), 
    ObjectId("51ee3966e4b056fe8f074f4b") 
] } } );

Answer 2

您可以使用命令deleteMany完成此操作。

const objects = [
    ObjectId("51ee3966e4b056fe8f074f48"), 
    ObjectId("51ee3966e4b056fe8f074f4a"), 
    ObjectId("51ee3966e4b056fe8f074f4b") 
];

db.collection.deleteMany({_id: { $in: objects}});
