使用agent-browser进行浏览器自动化

安装

推荐使用npm

npm install -g agent-browser
agent-browser install
agent-browser install --with-deps

从源代码安装

git clone https://github.com/vercel-labs/agent-browser
cd agent-browser
pnpm install
pnpm build
agent-browser install

快速开始

agent-browser open <url>        # Navigate to page
agent-browser snapshot -i       # Get interactive elements with refs
agent-browser click @e1         # Click element by ref
agent-browser fill @e2 "text"   # Fill input by ref
agent-browser close             # Close browser

核心工作流程

1. 导航：agent-browser open <url>
2. 快照：agent-browser snapshot -i（返回带有引用标识的元素，例如@e1、@e2）
3. 使用快照中的引用标识进行交互
4. 导航或DOM发生显著变化后重新生成快照

命令

导航

agent-browser open <url>      # Navigate to URL
agent-browser back            # Go back
agent-browser forward         # Go forward
agent-browser reload          # Reload page
agent-browser close           # Close browser

快照（页面分析）

agent-browser snapshot            # Full accessibility tree
agent-browser snapshot -i         # Interactive elements only (recommended)
agent-browser snapshot -c         # Compact output
agent-browser snapshot -d 3       # Limit depth to 3
agent-browser snapshot -s "#main" # Scope to CSS selector

交互（使用快照中的@引用标识）

agent-browser click @e1           # Click
agent-browser dblclick @e1        # Double-click
agent-browser focus @e1           # Focus element
agent-browser fill @e2 "text"     # Clear and type
agent-browser type @e2 "text"     # Type without clearing
agent-browser press Enter         # Press key
agent-browser press Control+a     # Key combination
agent-browser keydown Shift       # Hold key down
agent-browser keyup Shift         # Release key
agent-browser hover @e1           # Hover
agent-browser check @e1           # Check checkbox
agent-browser uncheck @e1         # Uncheck checkbox
agent-browser select @e1 "value"  # Select dropdown
agent-browser scroll down 500     # Scroll page
agent-browser scrollintoview @e1  # Scroll element into view
agent-browser drag @e1 @e2        # Drag and drop
agent-browser upload @e1 file.pdf # Upload files

获取信息

agent-browser get text @e1        # Get element text
agent-browser get html @e1        # Get innerHTML
agent-browser get value @e1       # Get input value
agent-browser get attr @e1 href   # Get attribute
agent-browser get title           # Get page title
agent-browser get url             # Get current URL
agent-browser get count ".item"   # Count matching elements
agent-browser get box @e1         # Get bounding box

检查状态

agent-browser is visible @e1      # Check if visible
agent-browser is enabled @e1      # Check if enabled
agent-browser is checked @e1      # Check if checked

截图与PDF

agent-browser screenshot          # Screenshot to stdout
agent-browser screenshot path.png # Save to file
agent-browser screenshot --full   # Full page
agent-browser pdf output.pdf      # Save as PDF

视频录制

agent-browser record start ./demo.webm    # Start recording (uses current URL + state)
agent-browser click @e1                   # Perform actions
agent-browser record stop                 # Stop and save video
agent-browser record restart ./take2.webm # Stop current + start new recording

录制会创建一个新的上下文，但保留您会话中的Cookie/存储数据。如果未提供URL，将自动返回至当前页面。为确保演示流畅，请先浏览，再开始录制。

等待

agent-browser wait @e1                     # Wait for element
agent-browser wait 2000                    # Wait milliseconds
agent-browser wait --text "Success"        # Wait for text
agent-browser wait --url "/dashboard"    # Wait for URL pattern
agent-browser wait --load networkidle      # Wait for network idle
agent-browser wait --fn "window.ready"     # Wait for JS condition

鼠标控制

agent-browser mouse move 100 200      # Move mouse
agent-browser mouse down left         # Press button
agent-browser mouse up left           # Release button
agent-browser mouse wheel 100         # Scroll wheel

语义定位器（替代引用）

agent-browser find role button click --name "Submit"
agent-browser find text "Sign In" click
agent-browser find label "Email" fill "user@test.com"
agent-browser find first ".item" click
agent-browser find nth 2 "a" text

会话（并行浏览器）

agent-browser --session test1 open site-a.com
agent-browser --session test2 open site-b.com
agent-browser session list

JSON输出（用于解析）

添加--json以获取机器可读输出：

agent-browser snapshot -i --json
agent-browser get text @e1 --json

调试

agent-browser open example.com --headed              # Show browser window
agent-browser console                                # View console messages
agent-browser console --clear                        # Clear console
agent-browser errors                                 # View page errors
agent-browser errors --clear                         # Clear errors
agent-browser highlight @e1                          # Highlight element
agent-browser trace start                            # Start recording trace
agent-browser trace stop trace.zip                   # Stop and save trace
agent-browser record start ./debug.webm              # Record from current page
agent-browser record stop                            # Save recording
agent-browser --cdp 9222 snapshot                    # Connect via CDP

故障排除

• 如果在 Linux ARM64 上找不到命令，请使用 bin 文件夹中的完整路径。
• 如果找不到元素，请使用快照来找到正确的引用。
• 如果页面未加载，请在导航后添加等待命令。
• 使用 `--headed` 参数以查看浏览器窗口进行调试。

选项

• `--session``<name>`使用一个隔离的会话。
• `--json` 提供 JSON 格式的输出。
• `--full` 截取整个页面的屏幕截图。
• `--headed` 显示浏览器窗口。
• `--timeout` 设置命令超时时间（以毫秒为单位）。
• `--cdp``<port>`通过 Chrome DevTools 协议进行连接。

注意事项

• 引用在每次页面加载时是稳定的，但在导航后会改变。
• 导航后务必进行快照以获取新的引用。
• 对于输入字段，请使用 `fill` 而非 `type`，以确保清除现有的文本。
