小编Amn*_*had的帖子

headers["user-agent"] = fakeUa();
  console.log(fakeUa())
  let firstReq = true;
    page.route('**/*', route => {
    const request = route.request()
    //console.log(request.url(), JSON.stringify(request.headers()));
    
    if("x-j3popqvx-a" in request.headers()){
        headers = request.headers();
        //console.log(headers);
        console.log("exiting");
        return;
    }
    else {
        console.log("in");
        return route.continue({headers: headers});
    }
  });
  let pageRes = await page.goto(url, {waitUntil: 'load', timeout: 0});

我想在向 url 发送请求时添加假用户代理。但它不会添加假用户代理，而是使用默认用户代理。

我的代码如下：

 const browser = await puppeteer.launch({headless: params["headless"]});

 
    const page = await browser.newPage();
    await page.setJavaScriptEnabled(true);
    await page.setRequestInterception(true);
...

问题是我无法运行它。我收到以下异常。

我有这个基本的帖子请求：

(async () => {

  // Create browser instance, and give it a first tab
    const browser = await puppeteer.launch({headless: false});
    const page = await browser.newPage();

    // Allows you to intercept a request; must appear before
    // your first page.goto()
    await page.setRequestInterception(true);


    // Request intercept handler... will be triggered with 
    // each page.goto() statement
    page.on('request', interceptedRequest => {

        // Here, is where you change the request method and 
        // add your post data
        var data = {
            'method': 'POST',
            'postData': …

我在 Windows 中安装了 azure cli。但我无法找到它的位置。我确实有一个名为 .azure 的文件夹，但我找不到其他任何内容。有什么办法可以查到它安装在哪里吗？就像蟒蛇一样

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 => {
    console.log(route.request());
    route.continue();
  });

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

当我在隐身窗口中打开它并使用 fiddler 拦截时，我能够获得这些标题：

但是我无法通过执行上面的代码来获取这些标头。我如何获得这些？

编辑：我使用了答案，效果很好。只有一个缺失的部分。
