puppeteer - Chrome puppeteer 在错误事件上关闭页面

Question

我想在 puppeteer 遇到任何错误时关闭页面，有时页面我尝试加载的页面崩溃并且它不调用 .close();

(async () => {
const page = await browser.newPage();
await page.setViewport({width: resWidth, height: resHeight});
await page.goto(d["entities"]["urls"][0]["expanded_url"], {timeout :90000});
await page.screenshot({path: './resimdata/'+d['id']+'.png' ,fullPage: true});
await page.close();
})();

puppeteer repo 上有一个关于此的问题/PR，这在类似情况下会有所帮助。

同时，你可以试试这个小技巧，如果0.12+版本有PR，我们就不用担心下面的代码了。

(async() => {
  const browser = await puppeteer.launch({headless: false});
  const page = await browser.newPage();

    function handleClose(msg){
        console.log(msg);
        page.close();
        browser.close();
        process.exit(1);
    }

    process.on("uncaughtException", () => {
        handleClose(`I crashed`);
    });

    process.on("unhandledRejection", () => {
        handleClose(`I was rejected`);
    });

    await page.goto("chrome://crash");

})();

这将输出如下内容，

▶ node app/app.js
I was rejected
