我对这个问题的公认答案感到非常失望。这是无法缩放的。如果你读了游标上的小字。跳过():

cursor.skip()方法通常开销很大，因为它需要服务器从集合或索引的开始处遍历以获得偏移或跳过位置，然后才开始返回结果。随着偏移量(例如上面的pageNumber)的增加，cursor.skip()将变得更慢，更消耗CPU。对于较大的集合，cursor.skip()可能成为IO绑定。

要以可伸缩的方式将limit()与至少一个筛选条件结合起来实现分页，createdOn日期适合多种用途。

MyModel.find( { createdOn: { $lte: request.createdOnBefore } } )
.limit( 10 )
.sort( '-createdOn' )

下面的代码是为我工作良好。 你也可以在countDocs查询中添加查找过滤器和user same来获得准确的结果。

export const yourController = async (req, res) => {
  const { body } = req;

  var perPage = body.limit,
  var page = Math.max(0, body.page);

  yourModel
    .find() // You Can Add Your Filters inside
    .limit(perPage)
    .skip(perPage * (page - 1))
    .exec(function (err, dbRes) {
      yourModel.count().exec(function (err, count) { // You Can Add Your Filters inside
        res.send(
          JSON.stringify({
            Articles: dbRes,
            page: page,
            pages: count / perPage,
          })
        );
      });
    });
};

您可以像这样编写查询。

mySchema.find().skip((page-1)*per_page).limit(per_page).exec(function(err, articles) {
        if (err) {
            return res.status(400).send({
                message: err
            });
        } else {
            res.json(articles);
        }
    });

Page:来自客户端作为请求参数的页码。 Per_page:每页显示的结果数目

如果你正在使用MEAN堆栈，下面的博客文章提供了很多信息，在前端使用angular-UI引导和在后端使用猫鼬跳过和限制方法创建分页。

参见:https://techpituwa.wordpress.com/2015/06/06/mean-js-pagination-with-angular-ui-bootstrap/

这是一个示例函数，用于获得具有分页和限制选项的技能模型的结果

 export function get_skills(req, res){
     console.log('get_skills');
     var page = req.body.page; // 1 or 2
     var size = req.body.size; // 5 or 10 per page
     var query = {};
     if(page < 0 || page === 0)
     {
        result = {'status': 401,'message':'invalid page number,should start with 1'};
        return res.json(result);
     }
     query.skip = size * (page - 1)
     query.limit = size
     Skills.count({},function(err1,tot_count){ //to get the total count of skills
      if(err1)
      {
         res.json({
            status: 401,
            message:'something went wrong!',
            err: err,
         })
      }
      else 
      {
         Skills.find({},{},query).sort({'name':1}).exec(function(err,skill_doc){
             if(!err)
             {
                 res.json({
                     status: 200,
                     message:'Skills list',
                     data: data,
                     tot_count: tot_count,
                 })
             }
             else
             {
                 res.json({
                      status: 401,
                      message: 'something went wrong',
                      err: err
                 })
             }
        }) //Skills.find end
    }
 });//Skills.count end
