Puppeteer cors犯了错误

Question

你好我的代码使用puppeteer有问题，cors错误随机发生，但在80％的测试中。这是我的代码感谢帮助。服务器响应是

从'https://secure-store.nike.com/eu/services/jcartService/?action=addItem&rt=json&country=GB&region=eu&lang_locale=en_GB&catalogId=1&productId=12238990&qty=1&skuId=21502246'获取'https://www.nike.com'的访问权限已被CORS政策阻止：请求的资源上没有“Access-Control-Allow-Origin”标头。如果不透明响应满足您的需求，请将请求的模式设置为“no-cors”以获取禁用CORS的资源。

const puppeteer = require('puppeteer');
const jsonfile = require('jsonfile')

function evaluate_click(element,page){
  page.evaluate((el) => {
     el.click()
  },element);
}

async function bot(){
const browser = await puppeteer.launch({headless: false})
const page = await browser.newPage()
setTimeout(function(){
    browser.close()
},120000)
await page.goto('https://www.nike.com/gb/launch/t/air-max-deluxe-midnight-navy-laser-orange-persian-violet/')
await page.waitForSelector('button.ncss-btn-accent.ncss-brand.pt3-sm.pb3-sm.pt2-lg.pb2-lg.u-uppercase.ta-sm-c.u-full-width')
await page.click('button.ncss-btn-accent.ncss-brand.pt3-sm.pb3-sm.pt2-lg.pb2-lg.u-uppercase.ta-sm-c.u-full-width')
await page.waitFor(1000)
await page.waitForSelector('button[aria-haspopup="true"]')
await page.click('button[aria-haspopup="true"]')
await page.waitForXPath("//ul[contains(@class,'')]//li[11]//button[1]")
var select_size = await page.$x("//ul[contains(@class,'')]//li[11]//button[1]")
await evaluate_click(select_size[0],page)
await page.waitFor(1000)
await page.waitForSelector('button.ncss-brand.ncss-btn-black.pb3-sm.prl5-sm.pt3-sm.u-uppercase.u-full-width')
await page.click('button.ncss-brand.ncss-btn-black.pb3-sm.prl5-sm.pt3-sm.u-uppercase.u-full-width')
await page.waitForSelector('a[data-qa="checkout-link"]')
await page.click('a[data-qa="checkout-link"]')

您可以将--disable-web-security标志传递给puppeteer.launch()以禁用Web安全性：

const browser = await puppeteer.launch({
  args: [
    '--disable-web-security',
  ],
  headless: false,
});
