如何檢查網絡流量並獲取資源請求的URL？

我想監視一個頁面的網絡並獲取JavaScript網絡事件的所有URL，類似於PhantomJS'page.onResourceRequested正在做的事情，但我無法弄清楚如何使用Google Chrome的Puppeteer完成此操作。如何檢查網絡流量並獲取資源請求的URL？

我已經涉足與Google Chrome's puppeteer，但我無法弄清楚如何使它工作，因爲它的輸出看起來是這樣的：

能否請你告訴我，我怎樣才能得到JavaScript與Puppeteer的網絡事件的所有網址？

查看攔截圖像請求的sample。易於修改，以查看其他類型的資源請求：

await page.setRequestInterceptionEnabled(true); 
page.on('request', request => { 
    if (/\.js$/i.test(request.url)) { 
    // request for js resource 
    } 
    request.continue(); 
}); 
await page.goto('https://example.com');
