在你开始之前运行脚本

Playwright是一个开源自动化库，旨在测试 Web 应用程序并自动与 Web 浏览器交互。它提供对浏览器操作的全面控制，包括导航、表单填写、元素点击和从网页提取数据。

在本文中，我们将提供一个简单的脚本，启动浏览器配置文件并将其与Playwright连接起来。

您可以使用Playwright为您的网络爬虫自动Mimic浏览器配置文件。请注意， Multilogin X中尚未提供Stealthfox的Playwright。

在你开始之前

JavaScript

从官方网站下载Node.js并安装
确保 Node.js 和 npm（Node 包管理器）已正确安装：

node -v 
npm -v

创建一个项目目录，然后运行此命令来初始化一个新的 Node.js 项目并创建一个package.json文件：

npm init -y

安装Playwright作为你的项目的依赖项：

npm install playwright

安装Axios和MD5库：

npm install axios 
npm install md5

将您的值插入到脚本中的以下变量中：
1. email ：您的Multilogin X账户电子邮件
2. password ：您的Multilogin X账户密码（无需MD5加密）
3. folder_id 、 profile_id ：使用DevTools或Postman上的指南查找这些值

Python

安装以下 Python 库：
1. 要求
2. 剧作家
安装必要的浏览器二进制文件：

playwright install

将您的值插入到脚本中的以下变量中：
1. USERNAME ：您的Multilogin X账户电子邮件
2. PASSWORD ：您的Multilogin X账户密码（无需MD5 加密）
3. FOLDER_ ID 、 PROFILE_ ID ：使用DevTools或Postman上的指南查找这些值

使用自动化代码运行.js文件

脚本示例

const { chromium } = require('playwright');
const md5 = require ('md5');
const axios = require('axios');

const HEADERS =  { 
  "Content-Type": "application/json", 
  "Accept": "application/json",
};
const acc_info = {
  // Insert your account information in both variables below
  "email": "",
  "password": md5("")
};

async function get_token() {
  const signIn_URL = "https://api.multilogin.com/user/signin";
  try {
    const response = await axios.post(signIn_URL, acc_info, { headers: HEADERS });
    return response.data.data.token;
  } catch (error) {
    console.log(error.message);
    console.log("Response data:", error.response.data);
    return false;
  }
};
// Insert the Folder ID and the Profile ID below
const folder_id = "";
const profile_id = "";

async function start_browserProfile(){
  const token = await get_token();
  if (!token) return;
  // Update HEADERS with bearer token retrived from the get_token function
  HEADERS.Authorization = 'Bearer ' + token;
  // Launch a profile defining "Playwright" as automation type
  const profileLaunch_URL = `https://launcher.mlx.yt:45001/api/v2/profile/f/${folder_id}/p/${profile_id}/start?automation_type=playwright&headless_mode=false`;
  try {
    const response = await axios.get(profileLaunch_URL, { headers: HEADERS });
    const browserURL = `http://127.0.0.1:${response.data.data.port}`;
    // if you prefer to connect with browserWSEndpoint, try to get the webSocketDebuggerUrl by following request
    // const {data : {webSocketDebuggerUrl}} = await axios.get(`${browserURL}/json/version`)
    const browser = await chromium.connectOverCDP(browserURL,{timeout:10000});
    const context = browser.contexts()[0];
    const page = await context.newPage();
    await page.goto("https://multilogin.com/");
    await page.screenshot({path: "example.png"});
    await page.close();
  } catch (error) {
    console.log("Error:", error.message);
    if (error.response) {
      console.log("Response data:", error.response.data); 
  } 
  }
};

start_browserProfile();
