在木偶中捕获错误ERR_CONNECTION_RESET

Question

我正在使用"puppeteer": "^1.16.0",测试我的网站是否可以承受代理服务器。

我开发了一个简短的木偶脚本，该脚本可以处理一系列代理，而且我的网站的响应应为：

在示例脚本下面找到：

function shuffle(dataObjArr) {
    let res = dataObjArr.sort(() => Math.random() - 0.5);
    return res
}

/**
 * Create random number between start and end value
 * @param {*} start 
 * @param {*} end 
 */
function randomNumberBetween(start, end) {
    return Math.floor(Math.random() * end) + start
}

/**
 * get 10 proxies from a list
 */
function getProxies() {
    // ...
    return proxies
}

async function main() {
    let issuerUrls = JSON.parse('[{"id":62,"name":"Product 1","ecomUrl":"/product/252","createdAt":"2019-05-25T07:51:49.000Z","updatedAt":"2019-05-25T07:51:49.000Z"},  {"id":15,"name":"Product 2","ecomUrl":"/product/251","createdAt":"2019-05-25T07:51:49.000Z","updatedAt":"2019-05-25T07:51:49.000Z"},  {"id":15,"name":"Product 2","ecomUrl":"/product/251","createdAt":"2019-05-25T07:51:49.000Z","updatedAt":"2019-05-25T07:51:49.000Z"},  {"id":15,"name":"Product 2","ecomUrl":"/product/251","createdAt":"2019-05-25T07:51:49.000Z","updatedAt":"2019-05-25T07:51:49.000Z"}]')

    let issuerUrlsShuffled = shuffle(issuerUrls)
    let BASE_URL = "https://www.webscraper.io/test-sites/e-commerce/allinone"

    let p = await getProxies();
    let proxies = [].concat(...p)
    let shuffledProxies = shuffle(proxies)
    let randNumbBool = true

    let i = 0
    let randNumb = 0
    // for (let i = 0; i < issuerUrlsShuffled.length; i++) {
    while (i < issuerUrlsShuffled.length) {

        if (randNumbBool) {
            randNumb = randomNumberBetween(0, shuffledProxies.length)
        }

        let proxy = '--proxy-server=' + shuffledProxies[randNumb].ipAddress + ":" + shuffledProxies[randNumb].port

        await puppeteer.launch({
            headless: false,
            args: ["--disable-notifications", proxy] // --proxy-server=127.0.0.1:9876 
        }).then(async browser => {
            const page = await browser.newPage()
            await page.setViewport({
                width: 800,
                height: 600
            })

            try {

                let URL = BASE_URL + issuerUrlsShuffled[i].ecomUrl;

                await page.goto(URL)

                page.waitForNavigation({
                    timeout: 0,
                    waitUntil: 'domcontentloaded'
                });

                await page.exposeFunction('formatDate', (date) =>
                    moment(date, 'M/DD/YYYY').toDate()
                );

                const data = await page.evaluate(async () => {

                    const priceData = []

                    let date = "9/23/2016" // this is needed for testing purposes only!!!

                    priceData.push({
                        price_date: await window.formatDate(date)
                    })
                    return priceData
                })

                // show data
                // should be emtpy!!!
                console.log(JSON.stringify(data, null, 2))

                await page.waitFor(3000)

                await browser.close()

                randNumbBool = false
                    ++i // next step in list
            } catch (error) {
                randNumbBool = true // get another random proxy
                console.log(error)
            }
        })
    }
}

main()

当我的网站对浏览器测试回应以上图片时，我的脚本停止运行，并且不再执行其他代理进行测试。

如何捕获错误ERR_CONNECTION_RESET，并仍然运行我的脚本以完成所有可用代理的测试。

提前谢谢！
