如何在 Playwright 中添加自定义标题

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。

而在木偶师这是可能的page.setUserAgent()应用自定义 UA 的方法和page.setExtraHTTPHeaders()设置任何自定义标头，在剧作家您可以设置自定义用户代理（userAgent) 和标题 (extraHTTPHeaders）作为选项browser.newPage() or browser.newContext() like:

const page = await browser.newPage({ userAgent: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36' })

const page = await browser.newPage({ 
  extraHTTPHeaders: { 
    'Cache-Control': 'no-cache' 
  } 
})

Edit:如果您将其与newContext()用法看起来像这样（确保设置userAgent在设置中newContext并且不在newPage!):

const context = await browser.newContext({ userAgent: 'hello' })
const page = await context.newPage()
// to check the UA:
console.log(await page.evaluate(() => navigator.userAgent))
