Browser Use的安装和使用

一、介绍

背景

• Browser Use：用AI控制你的浏览器，你可以使用它帮你购物、找资料并总结内容、发送邮件给你的老师等等。
• Browser Use UI：做了一个Browser Use的可视化界面，便于使用。

项目地址

• Browser Use
• Browser Use UI

二、安装教程

1、使用Conda创建虚拟环境

没有这个工具的可以去搜一下安装教程，非常好用的一个虚拟环境管理工具

conda create --name browser_use_env python=3.12 -y

2、激活环境

conda activate browser_use_env

3、安装browser use

pip install browser-use -i https://pypi.tuna.tsinghua.edu.cn/simple some-package

4、安装Playwright

playwright install

之前忘安装了，执行任务后出现下面错误，在命令行输入上面这个命令安装一下就行

5、克隆git仓库

git clone https://github.com/browser-use/web-ui.git

6、安装项目的依赖

pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple

三、使用教程

1、启动WebUI

python webui.py --ip 127.0.0.1 --port 7788

Agent Settings

这个页面可以控制BU最多执行步骤、每个步骤最多几个动作以及是否使用大模型的视觉推理能力，如果你调用的大模型没有视觉能力例如deepseek，记得把勾去掉，否则执行任务会失败。

LLM Configuration

大模型设置，主要填写API Key

Browser Settings

可以不动默认设置，我勾选过“Use Own Browser”，执行任务直接失败。

Run Agent

前面配置好了就可以在这里输入待执行任务，然后点击“Run Agent”就可以等待BU执行你的任务。任务的执行结果可以在页面的“Results”和“Recordings”查看，也可以在控制台中看BU每个步骤的思考过程和执行结果

2、案例1

• 任务： 打开网站https://www.csdn.net/?spm=1000.2115.3001.4476，找到用户madkeyboard并打开他最近的一篇博客文章，最后总结文章的内容
• API：使用的谷歌免费提供的gemini-2.0-flash
• 结果：无法执行任务，卡在Step1。我看网上有人用这个API执行任务成功，指出响应时间是分钟级别，不过我等了差不多8分钟还是卡在第一步，然后弹出一个空白的浏览器页面。

3、案例2

• 任务：打开网站https://www.csdn.net/?spm=1000.2115.3001.4476，找到页面的输入框并输入”madkeyboard“，然后点击用户，点击粉丝数量最多的”madkeyboard“，打开他最近的一篇博客文章，最后总结文章的内容。

• API：使用deepseek，注意deepseek并没有视觉推理能力，所以在使用时要把Agent Settings下面的User Vison去掉

• 结果：大致能完成任务，不过耗时太长了，效率远远比不上使用一些自动化脚本去完成该任务。首先BU会调用deepseek去分析用户的需求，然后拆分成若干步骤依次执行。相比案例1我重新描述了下任务需求，使其更加详细，因为前一次测试时BU操作浏览器进入CSDN网站后就无法找到搜索框进行下一步然后退出任务。BU执行的步骤中，导航到网页、搜索目标内容都没有问题，不过中途显示需要登录CSDN，这里需要人工登录一下，否则BU会由于CSDN登录失败无法显示搜索内容而重复搜索这一步骤，直到超过重试次数退出任务。此外，在BU执行任务时还弹出了一些广告栏（下图中选择您的身份是什么），不过没有影响后面任务的执行。BU在执行最后一个步骤找到用户最近的一篇博客并总结内容时输出的结果有些偏差，不知道为什么把20年一篇关于“JavaFX”的博客内容也写在答案里面了。

  

• API消耗量：官方统计token消耗的结果

  

• 小结：初次使用成功最大的感受就是效率太慢了，执行完整个任务花了大概6分钟，如果我自己用selenium写一个脚本去完成该任务可能20-30s就够了，而且还能保证任务成功率。

执行步骤

下面是BU执行任务时每个步骤的思考过程。
