Puppeteer 获取请求重定向 [英] Puppeteer get request redirects

问题描述

有什么方法可以使用 puppeteer 来获取请求的响应正文(如果有)的重定向?

Is there any way to use puppeteer to get the redirects with the response body (if there are any) of the request?

我实现了以下代码，但找不到获得重定向的方法...

I implemented the following code but I can't find a way to get the redirects...

const page = await browser.newPage()

page.on('request', (data) => console.log(data));    

await page.on('response', response => {
    const url = response.url();
    response.buffer()
    .then (
        buffer => {
            bufferString = buffer.toString();         
        },
        error => {
          console.log(error)
        }
    )
})

await page.goto('https://www.ford.com', {waitUntil: 'networkidle0'});

推荐答案

只需在 response 处理程序中检查 response.status() - 重定向将是 3xx:

Just check response.status() in your response handler - it will be 3xx for redirects:

page.on('response', response => {
  const status = response.status()
  if ((status >= 300) && (status <= 399)) {
    console.log('Redirect from', response.url(), 'to', response.headers()['location'])
  }
})

(重定向通常在响应正文中没有任何有趣的内容，因此您可能不想为它们调用 response.buffer().)

(Redirects don't usually have anything interesting in the response body, so you don't probably want to call response.buffer() for them.)
