从应用角度的NodeJS调用函数 [英] Call function in nodejs from angular application

问题描述

我有一个角应用（角种子应用程序），应调用一个的NodeJS功能（网络server.js）。
在该的NodeJS功能只是调用批处理文件。

I'm having an angular app(angular-seed app) which should call a function in nodejs(web-server.js). The function in nodejs is just calls a batch file.

推荐答案

该任择议定书没有提到前preSS所以我没有使用任何额外的框架，提供了服务器端（Node.js的一部分）的替代（这可能需要通过NPM安装它）。该解决方案只使用节点的核心：

The OP didn't mention express so I'll provide an alternative for the server side (Node.js part) without using any additional frameworks (which would require installing it via npm). This solution uses just node core:

网络server.js：

'use strict';

var http = require('http')
var spawn = require('child_process').spawn
var url = require('url')

function onRequest(request, response) {
  console.log('received request')
  var path = url.parse(request.url).pathname
  console.log('requested path: ' + path)
  if (path === '/performbatch') {
    // call your already existing function here or start the batch file like this:
    response.statusCode = 200
    response.write('Starting batch file...\n')
    spawn('whatever.bat')
    response.write('Batch file started.')
  } else {
    response.statusCode = 400
    response.write('Could not process your request, sorry.')
  }
  response.end()
}

http.createServer(onRequest).listen(8888)

假设你在Windows上，我会在第一次使用批处理文件这样来测试吧：

Assuming you are on Windows, I would at first use a batch file like this to test it:

whatever.bat：

REM Append a timestamp to out.txt
time /t >> out.txt

有关客户端，有什么要添加到 Spoike的解决方案。

For the client side, there is nothing to add to Spoike's solution.
