Puppeteer:如何听取具体的回应?

问题描述

我正在修改名为 puppeteer 的无头 chrome 节点 API.

I'm tinkering with the headless chrome node api called puppeteer.

我想知道如何听取特定的请求响应以及如何采取相应的行动.

I'm wondering how to listen to a specific request response and how to act in consequence.

我查看了事件 requestfinish 和 response 但它给了我所有页面中已经执行的请求/响应.

I have look at events requestfinish and response but it gives me all the request/responses already performed in the page.

如何实现评论行为?

谢谢！

推荐答案

一种选择是执行以下操作:

One option is to do the following:

  page.on('response', response => {
    if (response.url().endsWith("your/match"))
      console.log("response code: ", response.status());
      // do something here
  });

这仍然会捕获所有请求，但允许您过滤事件发射器并对其进行操作.

This still catches all requests, but allows you to filter and act on the event emitter.
