Casperjs Google登录(V2)不起作用

Question

i都使用casperjs(中间的phantomjs(来访问某些Google实用程序，但是，在访问它们之前，我们应该登录Google。对于V1 Google身份验证，我们使用以下脚本：

var casper = require('casper').create();
url = 'https://accounts.google.com/ServiceLogin?passive=1209600&continue=https%3A%2F%2Faccounts.google.com%2FManageAccount&followup=https%3A%2F%2Faccounts.google.com%2FManageAccount&flowName=GlifWebSignIn&flowEntry=ServiceLogin&nojavascript=1#identifier';
casper.start(url, function() {
  this.fillSelectors('form#gaia_loginform', {
    'input[name="Email"]': 'your@email',
  }); //Fills the email box with email
  this.click("#next");
  this.wait(500, function() { //Wait for next page to load
    this.waitForSelector("#Passwd", //Wait for password box
      function success() {
        console.log("SUCCESS...");
        this.fillSelectors('form#gaia_loginform', {
          'input[name="Passwd"]': 'yourPassw',
        }); //Fill password box with PASSWORD
        this.click("#signIn"); //Click sign in button
        this.wait(500, function() {}); //Wait for it fully sigin
        casper.thenOpen('http://utility.google.com/', function() {
            this.wait(2000, function() {
                this.capture('media/status.png', undefined, {
                    format: 'png',
                    quality: 100`enter code here`
                });
            });
        });
      },
      function fail() {
        console.log("FAIL...");
      }
    );
  });
});
casper.run();

我们改变了操纵表格并填充字段的方式，到目前为止它正在运行。V2身份验证的问题在于，无法触发鼠标事件，这意味着我们无法单击使用this.click("＃next"(和this.click("＃signin"(。我尝试使用不同的鼠标事件在表单上进行发布，并尝试直接操纵JSACTION事件。没有什么可用。

有人对如何解决这个问题有一个想法？非常感谢！

casper使用phantomjs，而幻影本身无法在Google帐户登录中登录。它似乎使用了phantomjs中不支持的任何ES6功能，它会默默失败。

也许您可以使用Beta phantomjs 2.5有更多运气。无论如何，phantomjs被弃用而不是Chrome无头。如Phantom维护者Vitaly Slobodin所说https://groups.google.com/forum/# !! topic/phantomjs/9ai5d-ldune

好消息是，您可以以：/opt/google/chrome/chrome --headless --disable-gpu --repl并做任何您想做的事情。

您可以用--remote-debugging-port=9224替换--repl，以在任何远程代码中控制它，例如Node中的程序...有图书馆像phantomjs一样控制它。高级(例如幻影(：https：//github.com/googlechrome/puppeteer较低的级别具有更多的控制力：https：//github.com/cyrus-and/chrome-remote-interface#clientdomainmethodparams-callback

目前，我对Puppeteer没有运气

const CDP = require('chrome-remote-interface');
const argv = require('minimist')(process.argv.slice(2));
const file = require('fs');

  // Enable events on domains we are interested in.
  await Page.enable();
  await DOM.enable();
  await Network.enable();
  // If user agent override was specified, pass to Network domain
  if (userAgent) {
    await Network.setUserAgentOverride({userAgent});
  }
  // Set up viewport resolution, etc.
  const deviceMetrics = {
    width: viewportWidth,
    height: viewportHeight,
    deviceScaleFactor: 0,
    mobile: false,
    fitWindow: false,

  await Emulation.setDeviceMetricsOverride(deviceMetrics);
  await Emulation.setVisibleSize({width: viewportWidth, height: viewportHeight});
  // Navigate to target page
  await Page.navigate({url});
  // Wait for page load event to take screenshot
  Page.loadEventFired(async () => {

我也尝试了同样的尝试，我发现点击正在使用this.click('#identifierNext');，而Google加载程序开始工作。如果您在单击屏幕截图后使用以下代码使用以下代码，则可以看到加载程序出现，但是在此之后，它不是进入密码屏幕，而是返回电子邮件屏幕。

屏幕截图代码

this.wait(200, function(){
    this.capture('1.jpg',{
        top: 0,
        left: 0,
        width: 4608, 
        height: 3456,
        quality:20
    });
});
this.wait(100, function(){
    this.capture('2.jpg',{
        top: 0,
        left: 0,
        width: 4608, 
        height: 3456,
        quality:20
    });
});
this.wait(100, function(){
    this.capture('3.jpg',{
        top: 0,
        left: 0,
        width: 4608, 
        height: 3456,
        quality:20
    });
});
this.wait(100, function(){
    this.capture('4.jpg',{
        top: 0,
        left: 0,
        width: 4608, 
        height: 3456,
        quality:20
    });
});

，但我也无法到达密码屏幕，如果有了这样的帮助，您可以告诉我任何想法。
