我正在尝试使用 puppeteer 构建一个网络抓取工具,它会抓取我的 venmo 页面以查找付款。当我尝试运行我的脚本时,我收到一条错误消息,指出“page.goto 不是函数”
老实说,我不太确定从哪里开始
const puppeteer = require('puppeteer');
const url = 'generic.com';
(async () => {
//running in headless to observe what happens for now
const browser = await puppeteer.launch({headless: false});
const page = browser.newPage();
await page.goto(url);
let data = await page.evaluate(() => {
let amount = document.querySelector('span.bold.medium.green').innerText;
let timePayed = document.querySelector('a.grey_link').innerText;
return {
amount,
timePayed
}
});
console.log(data);
debugger;
await browser.close();
})();
这是我的错误信息
UnhandledPromiseRejectionWarning: TypeError: page.goto is not a function

(node:13212) UnhandledPromiseRejectionWarning: Unhandled promise

最佳答案
线,
const page = browser.newPage();
应该写成,
const page = await browser.newPage();
browser.newPage() 返回 Promise 。
