关于 agent-browser

基于 CDP 的命令行浏览器自动化技能，适用于网页测试、CI 工作流和会话式抓取。它通过无障碍快照与元素引用进行交互，无需依赖 GUI 操作。

主要功能

  1. 01命令行浏览与页面交互
  2. 02带元素引用的无障碍快照
  3. 03表单填写与语义定位器
  4. 04会话和浏览器状态管理
  5. 05网络拦截与请求跟踪
  6. 06截图、PDF 和视频录制

适用场景

  1. 01在 CI 工作流中运行浏览器测试
  2. 02自动完成表单提交和登录流程
  3. 03通过会话式浏览抓取网页
  4. 04录制浏览器操作以制作演示或调试

详细介绍

使用 agent-browser 进行浏览器自动化

何时使用 agent-browser： 基于 CLI 的无头 CDP 自动化——无需浏览器扩展，也不使用像素级截图。适用于脚本化网页工作流、适配 CI 的浏览器测试，以及基于会话的抓取；在这些场景中，你更希望使用 shell 命令，而不是通过 GUI 交互。

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

  1. 导航：agent-browser open <url>
  2. 快照：agent-browser snapshot -i（返回带有 @e1、@e2 等引用标记的元素）
  3. 使用快照中的引用标记进行交互
  4. 导航或 DOM 发生重大变化后，重新生成快照

命令

导航
agent-browser open <url>      # Navigate to URL (aliases: goto, navigate)
                              # Supports: https://, http://, file://, about:, data://
                              # Auto-prepends https:// if no protocol given
agent-browser back            # Go back
agent-browser forward         # Go forward
agent-browser reload          # Reload page
agent-browser close           # Close browser (aliases: quit, exit)
agent-browser connect 9222    # Connect to browser via CDP port
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 @refs）
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 (alias: 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 option
agent-browser select @e1 "a" "b"  # Select multiple options
agent-browser scroll down 500     # Scroll page (default: down 300px)
agent-browser scrollintoview @e1  # Scroll element into view (alias: scrollinto)
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
agent-browser get styles @e1      # Get computed styles (font, color, bg, etc.)
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 "body" path.png  # Viewport screenshot to file
agent-browser screenshot --full "body" path.png  # Full page to file
agent-browser screenshot "body"           # Viewport screenshot (auto-saved to tmp)
agent-browser screenshot ".modal" modal.png  # Screenshot specific element
agent-browser pdf output.pdf              # Save as PDF

v0.9.1 注意事项：screenshot 要求将 CSS 选择器作为第一个位置参数。 使用 "body" 可截取整个视口。省略选择器会导致 Validation error: selector: Expected string, received null。

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

录制会创建新的上下文，但会保留会话中的 Cookie 和存储数据。如果未提供 URL，它会自动返回当前页面。若要制作流畅的演示，请先探索，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 (or -t)
agent-browser wait --url "**/dashboard"    # Wait for URL pattern (or -u)
agent-browser wait --load networkidle      # Wait for network idle (or -l)
agent-browser wait --fn "window.ready"     # Wait for JS condition (or -f)
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（替代引用标记）
agent-browser find role button click --name "Submit"
agent-browser find text "Sign In" click
agent-browser find text "Sign In" click --exact      # Exact match only
agent-browser find label "Email" fill "[email protected]"
