Question

在Google Cloud Functions中，当我尝试使用puppeteer时，我尝试的所有网站都收到以下错误，例如google.com：

Error: net::ERR_NAME_RESOLUTION_FAILED at http://www.google.com
    at navigate (/srv/node_modules/puppeteer/lib/FrameManager.js:101:37)
    at <anonymous>
    at process._tickDomainCallback (internal/process/next_tick.js:229:7)
  -- ASYNC --
    at Frame.<anonymous> (/srv/node_modules/puppeteer/lib/helper.js:110:27)
    at Page.goto (/srv/node_modules/puppeteer/lib/Page.js:656:49)
    at Page.<anonymous> (/srv/node_modules/puppeteer/lib/helper.js:111:23)
    at /srv/index.js:35:20
    at <anonymous>
    at process._tickDomainCallback (internal/process/next_tick.js:229:7)

云功能代码：

```
const functions = require("firebase-functions");
const cors = require("cors")({origin: true});
const Firestore = require("@google-cloud/firestore");
const puppeteer = require("puppeteer");
const cheerio = require("cheerio");

exports.getSiteOne = functions
  .runWith({ memory: "2GB" })
  .https.onRequest((req, res) => {
    cors(req, res, async function() {
      try {
        const browser = await puppeteer.launch({
          headless: true,
          args: ["--no-sandbox", "--disable-setuid-sandbox"]
        });
        const page = await browser.newPage();

        await page.setUserAgent('Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3419.0 Safari/537.36');

        await page.goto("http://www.google.com", {
          waitUntil: "networkidle0"
        });

        var html = await page.content();

        res.status(200).json({
          message: "cron added",
          html
        });
      } 
      catch (err) {
        console.log(err);
        res.status(500).json({
          error: err
        });
      }
    });
  });
```

该错误表明DNS查找失败。我假设您使用的是免费的"Spark Plan"。那是不允许任何传出流量：

出站网络：仅适用于Google服务
