如何登录Puppeteer？ [英] How to login in Puppeteer?

问题描述

我是javascript和puppeteer的新手。
我在下面尝试了一个登录代码并失败了。
相比之下，我添加了pages2并成功了。
我该如何解决？
提前致谢。

I'm new to javascript and puppeteer. I tried a login code below and failed. In comparison, I added pages2 and succeeded. How can I solved it? Thanks in advance.

const CREDS = require('./creds');

async function main() {
const puppeteer = require('puppeteer');
const browser = await puppeteer.launch({headless: false});

const page = await browser.newPage();
await page.setViewport({width: 1200, height: 720})
await page.goto('https://www.daum.net');
await page.waitForNavigation();
await page.type('#id', CREDS.username);
await page.type('#loginPw', CREDS.password);
await page.click('#loginSubmit');

const page2 = await browser.newPage();
await page2.setViewport({width: 1200, height: 720})
await page2.goto('https://google.com');
await page2.type('#lst-ib', 'Headless Chrome');
}

main();

推荐答案

page.waitForNavigation（） ; 在点击或从页面触发的任何导航操作后等待导航。你应该在page.click之后添加waitForNavigation。 / p>

page.waitForNavigation(); waits for navigation after a click or any navigation action that triggers from the page.you should probably add the waitForNavigation after the page.click.

await Promise.all([
      page.click('#loginSubmit'),
      page.waitForNavigation({ waitUntil: 'networkidle0' }),
]);

它会等到两个承诺结算。

It will wait until both promises resolves.

所以现在你的初始代码看起来像这样，

So now your initial code would look like this,

const puppeteer = require('puppeteer');
async function main() {
const browser = await puppeteer.launch({headless: false});
const page = await browser.newPage();
await page.setViewport({width: 1200, height: 720})
await page.goto('https://www.daum.net', { waitUntil: 'networkidle0' }); // wait until page load
await page.type('#id', CREDS.username);
await page.type('#loginPw', CREDS.password);
// click and wait for navigation
await Promise.all([
          page.click('#loginSubmit'),
          page.waitForNavigation({ waitUntil: 'networkidle0' }),
]);
}

main();

注意：回答一下，我无法测试这个，因为我没有<$ c的登录$ c> daum.net ，我看不到您面临的实际错误。如果您可以尝试上面提供的解决方案并分享结果，那将会更有帮助。

Note: Answer aside, I cannot test this since I don't have a login for daum.net and I cannot see the actual error you are facing. If you can try the solution provided above, and share the results, it'd be much more helpful.
