javascript - puppeteer :如何获取页面中发送/接收的总字节数

是否有任何puppeteer api /解决方法来获取页面中发送/接收的总字节数。例如下面的代码为我提供了所有时序统计信息。

await page.evaluate(() => JSON.stringify(window.performance.timing))

同样，有什么办法或解决方法，我可以获得页面中收到的总字节数/发送的总字节数。字节数应包括HTTP，Websocket，XHR请求/响应标头，正文。

最佳答案

通过使用

const perfEntries = JSON.parse(
  await page.evaluate(() => JSON.stringify(performance.getEntries()))
);

console.log(perfEntries);

您将获得所有请求的条目。添加所有请求的大小。

transferSize / encodedBodySize / decodedBodySize
