# Page Agent 浏览器插件 API
|
||||
|
||||
在你的网页应用中接入 Page Agent 插件,并通过页面 JavaScript 发起多页面浏览器任务。
|
||||
|
||||
## 安装
|
||||
|
||||
### 1. 安装浏览器插件
|
||||
|
||||
首选渠道:
|
||||
|
||||
- Chrome 应用商店:https://chromewebstore.google.com/detail/page-agent-ext/akldabonmimlicnjlflnapfeklbfemhj
|
||||
|
||||
通常更快提供最新构建的渠道:
|
||||
|
||||
- GitHub Releases:https://github.com/alibaba/page-agent/releases
|
||||
|
||||
### 2. 安装类型定义(推荐)
|
||||
|
||||
```bash
|
||||
npm install @page-agent/core --save-dev
|
||||
```
|
||||
|
||||
### 3. 授权(Token)
|
||||
|
||||
token 用于让页面 JS 调用扩展 API(`window.PAGE_AGENT_EXT`)并执行多页面任务。
|
||||
|
||||
为什么必须使用 token:
|
||||
|
||||
- 插件具备较广的浏览器权限(页面访问、导航、多标签控制)。
|
||||
- 若被滥用,可能危害用户隐私与安全。
|
||||
- 用户必须主动将 token 提供给其信任的应用。
|
||||
|
||||
配置步骤:
|
||||
|
||||
1. 在扩展侧边栏中复制 auth token。
|
||||
2. 在页面中设置 token:
|
||||
|
||||
```typescript
|
||||
localStorage.setItem('PageAgentExtUserAuthToken', 'your-token')
|
||||
```
|
||||
|
||||
## 快速开始
|
||||
|
||||
```typescript
|
||||
import type {
|
||||
AgentActivity,
|
||||
AgentStatus,
|
||||
ExecutionResult,
|
||||
HistoricalEvent,
|
||||
} from '@page-agent/core'
|
||||
|
||||
// 等待插件注入(最多 1 秒)
|
||||
async function waitForExtension(timeout = 1000): Promise<boolean> {
|
||||
const start = Date.now()
|
||||
while (Date.now() - start < timeout) {
|
||||
if (window.PAGE_AGENT_EXT) return true
|
||||
await new Promise((r) => setTimeout(r, 100))
|
||||
}
|
||||
return false
|
||||
}
|
||||
|
||||
// 使用
|
||||
if (await waitForExtension()) {
|
||||
const result = await window.PAGE_AGENT_EXT!.execute('点击登录按钮', {
|
||||
baseURL: 'https://api.openai.com/v1',
|
||||
apiKey: 'your-api-key',
|
||||
model: 'gpt-5.2',
|
||||
onStatusChange: (status) => console.log('状态:', status),
|
||||
onActivity: (activity) => console.log('活动:', activity),
|
||||
})
|
||||
console.log('结果:', result)
|
||||
}
|
||||
```
|
||||
|
||||
## 全局 API
|
||||
|
||||
token 匹配后,插件会在 `window` 上注入 API。
|
||||
|
||||
### `window.PAGE_AGENT_EXT_VERSION`
|
||||
|
||||
插件版本号字符串,可用于在访问主 API 前做能力检查。
|
||||
|
||||
### `window.PAGE_AGENT_EXT`
|
||||
|
||||
主命名空间对象。
|
||||
|
||||
#### `PAGE_AGENT_EXT.execute(task, config)`
|
||||
|
||||
执行 Agent 任务。
|
||||
|
||||
参数:
|
||||
|
||||
| 名称 | 类型 | 必填 | 说明 |
|
||||
| ---- | ---- | ---- | ---- |
|
||||
| `task` | `string` | 是 | 任务描述 |
|
||||
| `config` | `ExecuteConfig` | 是 | LLM 设置、执行选项和回调 |
|
||||
|
||||
返回:`Promise<ExecutionResult>`
|
||||
|
||||
#### `PAGE_AGENT_EXT.stop()`
|
||||
|
||||
停止当前任务。
|
||||
|
||||
## 类型定义
|
||||
|
||||
安装 `@page-agent/core` 获取完整类型:
|
||||
|
||||
```typescript
|
||||
import type {
|
||||
AgentActivity,
|
||||
AgentStatus,
|
||||
ExecutionResult,
|
||||
HistoricalEvent,
|
||||
} from '@page-agent/core'
|
||||
|
||||
export interface ExecuteConfig {
|
||||
baseURL: string
|
||||
apiKey: string
|
||||
model: string
|
||||
|
||||
// 是否包含启动脚本所在标签页。默认 true。
|
||||
includeInitialTab?: boolean
|
||||
|
||||
onStatusChange?: (status: AgentStatus) => void
|
||||
onActivity?: (activity: AgentActivity) => void
|
||||
onHistoryUpdate?: (history: HistoricalEvent[]) => void
|
||||
}
|
||||
|
||||
export type Execute = (task: string, config: ExecuteConfig) => Promise<ExecutionResult>
|
||||
```
|
||||
|
||||
`AgentStatus`
|
||||
|
||||
```typescript
|
||||
type AgentStatus = 'idle' | 'running' | 'completed' | 'error'
|
||||
```
|
||||
|
||||
`AgentActivity`
|
||||
|
||||
```typescript
|
||||
type AgentActivity =
|
||||
| { type: 'thinking' }
|
||||
| { type: 'executing'; tool: string; input: unknown }
|
||||
| { type: 'executed'; tool: string; input: unknown; output: string; duration: number }
|
||||
| { type: 'retrying'; attempt: number; maxAttempts: number }
|
||||
| { type: 'error'; message: string }
|
||||
```
|
||||
|
||||
`HistoricalEvent`
|
||||
|
||||
```typescript
|
||||
type HistoricalEvent =
|
||||
| { type: 'step'; stepIndex: number; reflection: AgentReflection; action: Action }
|
||||
| { type: 'observation'; content: string }
|
||||
| { type: 'user_takeover' }
|
||||
| { type: 'retry'; message: string; attempt: number; maxAttempts: number }
|
||||
| { type: 'error'; message: string; rawResponse?: unknown }
|
||||
```
|
||||
|
||||
`ExecutionResult`
|
||||
|
||||
```typescript
|
||||
interface ExecutionResult {
|
||||
success: boolean
|
||||
data: string
|
||||
history: HistoricalEvent[]
|
||||
}
|
||||
```
|
||||
|
||||
## 使用示例
|
||||
|
||||
### 基础执行
|
||||
|
||||
```typescript
|
||||
const result = await window.PAGE_AGENT_EXT!.execute(
|
||||
'在邮箱输入框填入 test@example.com 然后点击提交',
|
||||
{
|
||||
baseURL: 'https://api.openai.com/v1',
|
||||
apiKey: process.env.OPENAI_API_KEY!,
|
||||
model: 'gpt-5.2',
|
||||
includeInitialTab: false, // 可选:排除当前标签页
|
||||
onStatusChange: (status) => console.log(status),
|
||||
onActivity: (activity) => console.log(activity),
|
||||
}
|
||||
)
|
||||
```
|
||||
|
||||
### 停止当前任务
|
||||
|
||||
```typescript
|
||||
window.PAGE_AGENT_EXT!.stop()
|
||||
```
|
||||
|
||||
## Window 类型声明
|
||||
|
||||
如果你不直接引入 `@page-agent/core`,可添加以下声明:
|
||||
|
||||
```typescript
|
||||
import type {
|
||||
AgentActivity,
|
||||
AgentStatus,
|
||||
ExecutionResult,
|
||||
HistoricalEvent,
|
||||
} from '@page-agent/core'
|
||||
|
||||
interface ExecuteConfig {
|
||||
baseURL: string
|
||||
apiKey: string
|
||||
model: string
|
||||
includeInitialTab?: boolean
|
||||
onStatusChange?: (status: AgentStatus) => void
|
||||
onActivity?: (activity: AgentActivity) => void
|
||||
onHistoryUpdate?: (history: HistoricalEvent[]) => void
|
||||
}
|
||||
|
||||
declare global {
|
||||
interface Window {
|
||||
PAGE_AGENT_EXT_VERSION?: string
|
||||
PAGE_AGENT_EXT?: {
|
||||
version: string
|
||||
execute: Execute
|
||||
stop: () => void
|
||||
}
|
||||
}
|
||||
}
|
||||
```
