如何在page.evaluate中使用另一个模块？

Question

我需要在浏览器上下文之外调用外部api /模块，然后在if语句之后切换回puppeteer上下文。 感谢您的协助。

const puppeteer =require('puppeteer');

(async () => {
const browser = await puppeteer.launch({headless: false}); 
const page = await browser.newPage();
await page.goto('https://example.com');



await page.evaluate(() => {




var x = 
document.documentElement.outerHTML

var  s = x.includes('Example')


if (s = true) {
// **Must simply use other module / {api} and switch back to puppeteer
 context** 
}


});



})();
