Puppeteer 简明教程

Puppeteer - Disable JavaScript

我们可以使用 Puppeteer 禁用 JavaScript。为此，我们必须根据其类型阻止请求/响应。让我们尝试禁用 JavaScript 来启动页面。

We can disable JavaScript using Puppeteer. For this, we have to block the requests/response based on its type. Let us make an attempt to launch a page by disabling JavaScript.

首先，按照人偶基本测试章节执行步骤 1 至 2，如下所示 -

To begin, follow Steps 1 to 2 from the Chapter of Basic Test on Puppeteer which are as follows −

Step 1 - 在创建 node_modules 文件夹的目录中创建一个新文件（人偶和人偶核已安装的位置）。

Step 1 − Create a new file within the directory where the node_modules folder is created (location where the Puppeteer and Puppeteer core have been installed).

人偶安装的详情在人偶安装篇章中进行了讨论。

The details on Puppeteer installation is discussed in the Chapter of Puppeteer Installation.

右击创建 node_modules 文件夹的文件夹，然后点击新建文件按钮。

Right-click on the folder where the node_modules folder is created, then click on the New file button.

node modules

Step 2 - 输入文件名，如 testcase1.js。

Step 2 − Enter a filename, say testcase1.js.

testcase1 js

Step 3 - 将以下代码添加到新创建的 testcase1.js 文件中。

Step 3 − Add the below code within the testcase1.js file created.

//Puppeteer library
const pt = require('puppeteer')
pt.launch().then(async browser => {
//browser new page
   const page = await browser.newPage()
   //monitor requests
   await page.setRequestInterception(true)
   //check resourceType is script
   page.on('request', request => {
      if (request.resourceType() === 'script')
         request.abort();
      else
         request.continue();
   })
   //launch application
   await page.goto('https://www.tutorialspoint.com/index.htm')
   //browser close
   await browser.close()
})

Step 4 - 使用以下命令执行代码 -

Step 4 − Execute the code with the command given below −

node <filename>

因此，在我们的示例中，我们将运行以下命令 -

So in our example, we shall run the following command −

node testcase1.js
