Question

我正在使用Vue.js作为客户端框架来构建Electron应用程序。当我尝试运行节点脚本时，出现未捕获（承诺）TypeError：self._form.on不是函数

我不确定这是否是由于它是通过电子在浏览器上运行的，但是当我通过控制台中的Node运行脚本时，它运行良好。甚至可以运行此节点脚本客户端吗？我通过要求文件通过前端vue.js组件之一运行节点文件。 让raffleScript = require（'../ raffles / index.js'）;

节点脚本：

var cheerio = require('cheerio');
var fs = require('fs');

var retryDelay = 300; 
var tasks = 200; 


var userAgent = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36';
var tasksComplete = 0;
var exportedCount = 0;
// Export the values
//setInterval(countUpdate, 4000);

initProxies();

function sleep(ms) {
    return new Promise(resolve => setTimeout(resolve, ms));
  }

async function initProxies() {
    for (var i = 0; i < tasks; i++) {
        submitRaffle(i);
        await sleep(retryDelay);
        // setTimeout(function () {
        //  submitRaffle(i);
        // }, retryDelay)
    }
}

function submitRaffle(taskNum) {
    var jar = require('request').jar()
    var request = require('request').defaults({
        jar: jar
    });


    console.log('Making request.............................');
    request({
        url: 'bungeedesign.com/dev',
        method: 'POST',
        headers: {

            'Content-Type': 'application/x-www-form-urlencoded'
        },
        formData: 
        { firstname: 'James',
          name: '',
          lastname: 'Rogers',
          mobileNumber: '00000000',
          email: 'email@email.com',
          raffle_type: 'Development',
          checkbox_0: 'Backend',
          personal_or_business: 'Personal',
          model: 'Register Of Interests',
          'submit-0': 'Keep me posted' },
    }, function (error, response, body) {
        // console.log('REQ RES --------->>>> ', response);
        //console.log('Req Completed', response);
        if (error) {
            console.log('Error.............................');
            setTimeout(function () {
                submitRaffle(taskNum)
            }, retryDelay)
            return;
        }
        $ = cheerio.load(body);
        if (response.statusCode == 302) {
            //if (JSON.parse(body).message == "successfully") {
                console.log('\x1b[1;32m', "[" + taskNum + "] - Raffle entry submitted");
                tasksComplete++;
                //module.exports.exportedCount = tasksComplete;
                console.log('\x1b[1;32m', "[" + taskNum + "] - " + tasksComplete + " Entries submitted.")
            //}
        } else {
            setTimeout(function () {
                submitRaffle(taskNum)
            }, retryDelay)
            return;
        }
    });
}


// Increment Exports

// function countUpdate() {
//  module.exports.exportedCount = exportedCount++;
// }

Main.vue组件（脚本）

无法使其与“节点请求”模块一起使用。我尝试了Axios，尽管我在CORS方面遇到了一些问题，但是仍然可以使用。然后，我遇到了工作得很好的Needle https://www.npmjs.com/package/needle！

不确定使用formData时节点请求为何不起作用。

在电子应用程序中使用节点请求时获取“ self._form.on不是函数”
