多线程中的电子过程在发生错误后不会关闭

Question

情况： 我想创建一个多线程脚本，我用CSV加载IP列表和帐户信息。 我加载数据并调用一个函数，我打开电子并与Vo一起运行我的恶梦脚本。在剧本里面，我去了一个网站，循环浏览一个链接列表，检查是否有人住在澳大利亚。 当我有错误时，例如Timeout，浏览器停止工作。 错误示例 - ＆gt;

{ message: 'navigation error',
  code: -7,
  details: 'Navigation timed out after 30000 ms',
  url: 'https://facebook.com/login' }

这是我的代码

var fs = require('fs');
var csv = require('fast-csv');
var vo = require('vo');
var Nightmare = require('nightmare');

    var count = 0;
    var urls = fs.readFileSync('uniqueIds.csv').toString().split("\n");

    var arrayUrls = Object.keys(urls).map(function (key) {return urls[key]});

    var bloqNumber = 0;
    function *run(proxy, user, pass, urlsID) {
        var nightmare = new Nightmare({ 
            webPreferences: { partition: 'your-custom-partition'},
            switches:{
            'proxy-server': proxy,
            'ignore-certificate-errors': true
        }, show: true });

        yield nightmare
        .goto('https://facebook.com/login')
        .wait(".inputtext._55r1.inputtext._1kbt.inputtext._1kbt")

        .wait(29000);

        var range = urlsID * 2000;
        var rangeStart = range - 2000;
        var urlsarray = arrayUrls.slice(rangeStart, range);

期望的结果： 我希望每次我得到某种错误，我的线程正在关闭。

解决。只需在下面的示例中附加.catch即可。

yield nightmare
.goto('https://facebook.com/login')
.wait(".inputtext._55r1.inputtext._1kbt.inputtext._1kbt")
.type('input[name="email"]', user)
.type('input[name="pass"]', pass)
.click('button[name=login]')
.wait(29000).catch(function(err){
                  console.dir(err);
                  nightmare.end();
                });
