(节点:11340)不建议使用警告:不推荐使用collection.findAndModify。使用findOneAndUpdate,findOneAndReplace或findOneAndDelete代替

我在api nodejs上有一个方法发布,而在angular上有一个客户端应用程序,当我在邮递员上测试方法发布时,这项工作有效,但是当我从客户端应用程序发送数据时,它不起作用:

这是我的代码nodejs api:

'use strict'

var historial = require('../models/historial');

var controller={

    saveHistorial: function(req, res){
        console.log("entro")
        var Historial = new historial();

        var params = req.body;
        Historial.nombre= params.nombre;
        Historial.cantidad= params.cantidad;
        Historial.unidadMedida= params.unidadMedida;
        Historial.fecha= params.fecha;
        Historial.costo= params.costo

        Historial.save((err, HistorialStored)=>{
            if(err)return res.status(500).send({message: 'error en la peticion'});
            if(!HistorialStored) return res.status(404).send({message: 'no se ha podido guardar'});

            return res.status(200).send({Historial: HistorialStored});
        });
    },

    getHistorial: function(req, res){
        historial.find({}).exec((err, Historial)=> {
            if(err) return res.status(500).send({message: 'error al devolver los datos'});
            if(!Historial) return res.status(404).send({message:'No hay Historials'});
            return res.status(200).send({Historial});
        });
    },

};

module.exports = controller;

这是我对angular的服务:

import { Injectable } from '@angular/core';
import {HttpClient, HttpHeaders} from '@angular/common/http';
import {Observable} from 'rxjs/Observable';
import {historial} from '../models/historial';
import {Global} from './global';


@Injectable({
  providedIn: 'root'
})
export class HistorialService {
public url: string; 

  constructor(private _httpclient:HttpClient ) { 

    this.url= Global.url;
  }

  saveRegistro(_historial:historial): Observable<any>{
      let params = JSON.stringify(_historial);
      let headers = new HttpHeaders().set('Content-Type', 'application/json');
      debugger
      return this._httpclient.post(this.url + 'save-registro', params, {headers: headers});
   }


   getHistorial():Observable<any>{
      let headers = new HttpHeaders().set('Content-Type', 'application/json');

      return this._httpclient.get(this.url+'historial', {headers:headers});
   }
}

当我执行此服务时,服务器上的控制台上会出现此错误:

(node:11340) DeprecationWarning: collection.findAndModify is deprecated. Use findOneAndUpdate, findOneAndReplace or findOneAndDelete instead.
