const { webkit } = require('playwright');

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

  // Log and continue all network requests
  page.route('**', route => {

    route.continue();
  });

  await page.goto('https://www.sahibinden.com');
  //await browser.close();

但是我无法通过执行上述代码来获取这些标头。我如何得到这些？

编辑：我使用了答案，它工作正常。只有一个缺失的部分。

page.route('**', route => {
    const request = route.request()
    //console.log(request.url(), JSON.stringify(request.headers()));
    return route.continue();
  });
  let pageRes = await page.goto(url);
  await page.waitForTimeout(3 * 1000)
  //await page.unroute("**");
  return pageRes;

当我打印 PageRes.request().headers() 它没有给出 j3pop 标题。它只是给出

{
  accept: 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
  'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_4) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/13.2 Safari/605.1.15'
}

编辑：这是我在交互式剧作家中尝试过的

const { webkit } = require('playwright');

(async () => {
  const browser = await webkit.launch();
  const context = await browser.newContext();
  const page = await context.newPage();

  // Log and continue all network requests
  headers = {}
  page.route('**/*', route => {
    const request = route.request()
    console.log(request.url(), JSON.stringify(request.headers()));
    headers = JSON.stringify(request.headers());
    return route.continue();
  });

  let url = await page.goto('https://www.sahibinden.com/en/cars?sorting=date_desc');
  console.log("headerw");
  console.log(headers)
  await page.waitForTimeout(3 * 1000)
  
  await browser.close();
})();

标头没有给我 j3pop 标头

问题是，在从浏览器的角度完全加载页面后，将发出请求。因此，您必须使用waitForTimeout等待 X 毫秒之类的东西，或者waitForSelector如果您有一个元素最终会在您的请求发出后出现，则使用它。

请参阅这个稍作修改的示例，它会再等待 3 秒，然后将带有特殊标头的请求记录到控制台。

const { webkit } = require('playwright');

(async () => {
  const browser = await webkit.launch();
  const context = await browser.newContext();
  const page = await context.newPage();

  // Log and continue all network requests
  await page.route('**', route => {
    const request = route.request()
    console.log(request.url(), JSON.stringify(request.headers()));
    return route.continue();
  });

  await page.goto('https://www.sahibinden.com');
  await page.waitForTimeout(3 * 1000)
  await browser.close();
})();

您需要在await之前添加，page.route(...否则运行时可能尚未设置路由page.goto。

参考：https ://playwright.dev/docs/api/class-page#page-route
