Node.js 木偶演员1.16.0可以'；t导航到https://google.ca?

运行

npm audit fix

fto修复漏洞后，Pupeter不再能够导航到任何东西，甚至连谷歌也不能

npm列表显示我正在使用1.16.0

在名为

invoice\u to_pdf.js的脚本中：

  2 const puppeteer = require('puppeteer');
...
 18 const headers = new Map();
...
 31 console.log("Starting " + new Date());
 32 
 33 
 34 (async () => {
 35   const browser = await puppeteer.launch();
 36   const page = await browser.newPage();
 37   await page.setExtraHTTPHeaders(headers);
 38   page.setDefaultNavigationTimeout(50000)
 39 
 40   process.on("unhandledRejection", (reason, p) => {
 41             console.error("Unhandled Rejection at: Promise", p, "reason:", reason);
 42             browser.close();
 43             process.exit(1)
 44   });
 45 
 46   url = 'https://google.ca'
 47   console.log(`For testing, navigating to ${url}`);
 48   await page.goto(url);
 49   console.log(`Waiting for naviation to ${url}`);
 50   await page.waitForNavigation({waitUntil: 'load'});
 51   console.log(`Arrived at ${url}`);
 52 

输出为：

你能试试吗

wait page.waitForNavigation（{waitUntil:'networkidle2'}）

而不是

wait page.waitForNavigation（{waitUntil:'load'}）
在此代码中：

 48   await page.goto(url);
 49   console.log(`Waiting for naviation to ${url}`);
 50   await page.waitForNavigation({waitUntil: 'load'});

。。。
waitForNavigation
不是必需的：

 64   url = 'https://google.ca'
 65   console.log(`For testing, navigating to ${url}`);
 66   await page.goto(url);
 67   console.log(`Arrived at ${url}`);

输出：

For testing, navigating to https://google.ca
Arrived at https://google.ca

wait
执行等待
goto
完成的任务

它有一个
页面。单击
必须使用
waitForNavigation
。我还看到了必须在调用
页面之前创建的引用（，）。单击
：

80   logInAwait = page.waitForNavigation({waitUntil: ['networkidle0', 'load', 'domcontentloaded']});
 81   await page.click('[name="commit"]')
 82   console.log("logging in....");
 83
... 
 87   await logInAwait

反馈最受欢迎，因为我不认为自己是JS专家。
当无头模式的转动时，你能检查你是否在导航？const浏览器=等待木偶程序。启动（{无头：false，}）；我在{headless:false，}中看到了相同的输出。我正在通过远程连接执行，也许明天当我站在执行机器前面时，我会看到一些不同的东西。我运行了一个较小的脚本，并直接从命令行执行（OP是在bash脚本中调用的）。浏览器出现了，但我仍然得到相同的
，等待导航http://google.ca
直到我关闭浏览器：抱歉，我忘了在出现此问题时提到我们已经在使用networkidle2。我再次测试它只是为了确定是否发生了相同的超时行为：。我将尝试下一步关闭无头。
80   logInAwait = page.waitForNavigation({waitUntil: ['networkidle0', 'load', 'domcontentloaded']});
 81   await page.click('[name="commit"]')
 82   console.log("logging in....");
 83
... 
 87   await logInAwait
