Question

在网络上看不到涵盖Angular2和SailsJS Resourceful Pub / Sub场景的任何内容。我正在尝试观看新记录的模型并在我的Angular2应用程序中显示它们。我正在使用angular2-sails模块。下面的代码成功将数据导入我的角度应用程序，但需要页面刷新才能获取新数据。目标是在不刷新页面的情况下实时获取数据。

Sails Controller Actions：

  ngOnInit() {
    let sails = this._sailsService;
    sails.connect("http://localhost:1337")
    sails.get('/socket/getCalls')
    .subscribe(
      (resData) => { this.calls = resData.data.length},
      (error) => { console.log("oooops, error occured") },
      () => { console.log("we are finished") }
    )
  }

Angular2组件：

import os, sys, urllib2, urllib, zipfile, arcpy
from arcpy import env

path = os.getcwd()

def pickData():
    myCount = 1
    path1 = 'path2URL'
    response = urllib2.urlopen(path1)
    print "Enter the name of the files you need"
    numZips = raw_input()
    numZips2 = numZips.split(",")
    myResponse(myCount, path1, response, numZips2)

def myResponse(myCount, path1, response, numZips2):
    myPath = os.getcwd()
    for each in response:
        eachNew = each.split("  ")
        eachCounty = eachNew[9].strip("\n").strip("\r")
        try:
            myCountyDir = os.mkdir(os.path.expanduser(myPath+ "\\counties" + "\\" + eachCounty))
        except:
            pass
        myRetrieveDir = myPath+"\\counties" + "\\" + eachCounty

只需要.on("model")我.publishCreate

 sails.on("call")
  .subscribe(
  (resData) => {
    this.call_count = this.call_count + 1;
    this.calls_realtime.push(resData.data);
  },
  (error) => { console.log("Error") },
  () => { console.log("End") }
  )
