我非常喜欢异步/等待功能的Express/Mongoose应用程序中的这种模式:

app.delete('/:idToDelete', asyncHandler(async (req, res) => {
  const deletedItem = await YourModel
    .findByIdAndDelete(req.params.idToDelete) // This method is the nice method for deleting
    .catch(err => res.status(400).send(err.message))

  res.status(200).send(deletedItem)
}))

这招对我很管用，试试这个:

const id = req.params.id;
      YourSchema
      .remove({_id: id})
      .exec()
      .then(result => {
        res.status(200).json({
          message: 'deleted',
          request: {
            type: 'POST',
            url: 'http://localhost:3000/yourroutes/'
          }
        })
      })
      .catch(err => {
        res.status(500).json({
          error: err
        })
      });

你可以随时使用Mongoose内置函数:

var id = req.params.friendId; //here you pass the id
    FBFriendModel
   .findByIdAndRemove(id)
   .exec()
   .then(function(doc) {
       return doc;
    }).catch(function(error) {
       throw error;
    });

db.collection.remove(<query>,
 {
  justOne: <boolean>,
  writeConcern: <document>
})

model.remove({title:'danish'}, function(err){
    if(err) throw err;
});

裁判:http://mongoosejs.com/docs/api.html # model_Model.remove

如果只寻找一个要删除的对象，则可以使用

Person.findOne({_id: req.params.id}, function (error, person){
        console.log("This object will get deleted " + person);
        person.remove();

    });

在本例中，Mongoose将根据匹配的req.params.id进行删除。
