**遇到以下情况立即切换到 explorer,不要在 oneshot 里继续硬撑:**
- Step 3 验证 fetch 始终拿不到数据(签名/风控,非 cookie/header 能解决的)
- 需要 Pinia Store Action 触发 API
- 同一站点要生成 2 个以上命令
- `opencli browser network` 完全空,JS bundle 里也找不到 baseURL

## 输入
| 项目 | 示例 |
|------|------|
| **URL** | `https://x.com/jakevin7/lists` |
| **Goal** | 获取我的 Twitter Lists |
---
## 流程
### Step 1: 打开页面 + 抓包
```bash
opencli browser open <目标 URL> # 打开目标页面(自动开始抓包)
opencli browser wait time 3 # 等页面加载完、API 请求触发
opencli browser network # 查看捕获的 JSON API 请求
```
**关键**:`network` 默认已过滤静态资源,只显示 JSON/XML/text 的 API 请求。
如果没有自动触发 API,用 `opencli browser state` 找到按钮索引,`opencli browser click <N>` 点击后再 `network` 抓一次。
**`network` 为空?** ① 重新 `open` 刷新捕获窗口;② 如果是 SPA,API domain 可能是 `api.xxx.com` 而非 `app.xxx.com`,用 Step 2 里的 bundle 搜索找真实 baseURL。
### Step 2: 锁定一个接口
从 `opencli browser network` 结果中找到**那个**目标 API,用 `--detail` 查看完整响应:
```bash
opencli browser network --detail <N> # 查看第 N 条请求的完整响应体
```
关注这几个字段:
| 字段 | 关注什么 |
|------|----------|
| URL | API 路径 pattern(如 `/i/api/graphql/xxx/ListsManagePinTimeline`) |
| Method | GET / POST |
| Headers | 有 Cookie? Bearer? CSRF? 自定义签名? |
| Response | 数据在哪个路径(如 `data.list.lists`) |
> **SPA 注意**:如果 `network` 里 API 的 host 和页面 host 不同(如 `api.xxx.com` vs `app.xxx.com`),后续 `fetch` 要用完整 URL。
> 如果 `network` 完全没有 API 请求,搜 JS bundle 找 baseURL:
> ```bash
> opencli browser eval "(async()=>{const s=[...document.querySelectorAll('script[src]')].map(e=>e.src).find(s=>s.match(/index|main|app/));const t=await fetch(s).then(r=>r.text());const m=t.indexOf('baseURL')>-1?t.indexOf('baseURL'):t.indexOf('baseUrl');return m>-1?t.slice(m-10,m+80):'not found'})()"
> ```
### Step 3: 验证接口能复现
用 `opencli browser eval` 在页面内 `fetch` 复现请求:
```bash
# Tier 2 (Cookie): 传统网站
opencli browser eval "fetch('/api/endpoint', { credentials: 'include' }).then(r => r.json())"
# Tier 2.5 (localStorage Bearer): 现代 SaaS 主流(slock、Linear、Notion 等)
opencli browser eval "(async () => {
const token = localStorage.getItem('access_token'); // 换成实际 key
const res = await fetch('https://api.example.com/endpoint', {
headers: { 'Authorization': 'Bearer ' + token },
credentials: 'include'
});
return res.json();
})()"
# Tier 3 (Header): 如 Twitter 需要额外 header
opencli browser eval "(async () => {
const ct0 = document.cookie.match(/ct0=([^;]+)/)?.[1];
const res = await fetch('/api/endpoint', {
headers: { 'Authorization': 'Bearer ...', 'X-Csrf-Token': ct0 },
credentials: 'include'
});
return res.json();
})()"
```
> 带了 Bearer 但返回 `{ error: "Missing X-Xxx-Id header" }`(HTTP 400)→ 多租户 SaaS 需要业务上下文 Header。先调 `/servers` 或 `/workspaces` 拿 ID,再加进 headers。
如果 fetch 能拿到数据 → 用 TS adapter(`cli()` pipeline 或 `func()`)。
如果 fetch 拿不到(签名/风控)→ 用 intercept 策略(TS `func()` + `installInterceptor`)。
### Step 4: 套模板,生成 adapter
根据 Step 3 判定的策略,选一个模板生成文件。
---
## 认证速查
```
fetch(url) 直接能拿到? → Tier 1: public (browser: false)
fetch(url, {credentials:'include'})? → Tier 2: cookie
localStorage 有 token + Bearer header 能拿到? → Tier 2.5: localStorage Bearer ← 现代 SaaS 主流
带了 Bearer 但返回 400 "Missing X-Xxx header"? → 先拿业务上下文 ID,加进 header
加 CSRF/Bearer header 后拿到? → Tier 3: header
都不行,但页面自己能请求成功? → Tier 4: intercept (installInterceptor)
```

## 模板
### JS — Cookie/Public(最简,`func()` 模式)
```javascript
// clis/<site>/<name>.js
import { cli, Strategy } from '@jackwener/opencli/registry';
cli({
site: 'mysite',
name: 'mycommand',
description: '一句话描述',
domain: 'www.example.com',
strategy: Strategy.COOKIE, // 或 Strategy.PUBLIC (加 browser: false)
browser: true,
args: [
{ name: 'limit', type: 'int', default: 20 },
],
columns: ['rank', 'title', 'value'],
func: async (page, kwargs) => {
await page.goto('https://www.example.com/target-page');
const data = await page.evaluate(`(async () => {
const res = await fetch('/api/target', { credentials: 'include' });
const d = await res.json();
return (d.data?.items || []).map(item => ({
title: item.title,
value: item.value,
}));
})()`);
return (data as any[]).slice(0, kwargs.limit).map((item, i) => ({
rank: i + 1,
title: item.title || '',
value: item.value || '',
}));
},
});
```
### JS — localStorage Bearer(现代 SaaS)
```javascript
// clis/<site>/<name>.js
import { cli, Strategy } from '@jackwener/opencli/registry';
cli({
site: 'mysite',
name: 'mycommand',
description: '一句话描述',
domain: 'app.example.com',
strategy: Strategy.COOKIE,
browser: true,
args: [
{ name: 'limit', type: 'int', default: 20 },
],
columns: ['rank', 'title', 'value'],
func: async (page, kwargs) => {
await page.goto('https://app.example.com');
const data = await page.evaluate(`(async () => {
const token = localStorage.getItem('access_token');
// 多租户 SaaS:先拿工作空间 ID
const servers = await fetch('https://api.example.com/api/servers', {
headers: { 'Authorization': 'Bearer ' + token }
}).then(r => r.json());
const server = servers[0];
const res = await fetch('https://api.example.com/api/items', {
headers: { 'Authorization': 'Bearer ' + token, 'X-Server-Id': server.id }
});
return res.json();
})()`);
return (data as any[]).slice(0, kwargs.limit).map((item, i) => ({
rank: i + 1,
title: item.title || '',
value: item.value || '',
}));
},
});
```
### JS — Intercept(抓包模式)
```javascript
// clis/<site>/<name>.js
import { cli, Strategy } from '@jackwener/opencli/registry';
cli({
site: 'mysite',
name: 'mycommand',
description: '一句话描述',
domain: 'www.example.com',
strategy: Strategy.INTERCEPT,
browser: true,
args: [
{ name: 'limit', type: 'int', default: 20 },
],
columns: ['rank', 'title', 'value'],
func: async (page, kwargs) => {
// 1. 导航
await page.goto('https://www.example.com/target-page');
await page.wait(3);
// 2. 注入拦截器(URL 子串匹配)
await page.installInterceptor('target-api-keyword');
// 3. 触发 API(滚动/点击)
await page.autoScroll({ times: 2, delayMs: 2000 });
// 4. 读取拦截的响应
const requests = await page.getInterceptedRequests();
if (!requests?.length) return [];
let results: any[] = [];
for (const req of requests) {
const items = req.data?.data?.items || [];
results.push(...items);
}
return results.slice(0, kwargs.limit).map((item, i) => ({
rank: i + 1,
title: item.title || '',
value: item.value || '',
}));
},
});
```
### TS — Header(如 Twitter GraphQL)
```typescript
import { cli, Strategy } from '@jackwener/opencli/registry';
import { AuthRequiredError } from '@jackwener/opencli/errors';
cli({
site: 'twitter',
name: 'mycommand',
description: '一句话描述',
domain: 'x.com',
strategy: Strategy.HEADER,
browser: true,
args: [
{ name: 'limit', type: 'int', default: 20 },
],
columns: ['rank', 'name', 'value'],
func: async (page, kwargs) => {
await page.goto('https://x.com');
const data = await page.evaluate(`(async () => {
const ct0 = document.cookie.match(/ct0=([^;]+)/)?.[1];
if (!ct0) return { error: 'Not logged in' };
const bearer = 'AAAAAAAAAAAAAAAAAAAAANRILgAAAAAAnNwIzUejRCOuH5E6I8xnZz4puTs%3D...';
const res = await fetch('/i/api/graphql/QUERY_ID/Endpoint', {
headers: {
'Authorization': 'Bearer ' + decodeURIComponent(bearer),
'X-Csrf-Token': ct0,
'X-Twitter-Auth-Type': 'OAuth2Session',
},
credentials: 'include',
});
return res.json();
})()`);
if ((data as any).error) throw new AuthRequiredError('x.com');
// 解析 data...
return [];
},
});
```

## 测试(必做)
<!-- keep in sync with explorer SKILL.md §Step4 -->
> **两种开发场景**:
> - **Repo 贡献**:文件放 `clis/<site>/<name>.js`,`npm run build` 后自动注册
> - **私人 adapter**(本地使用,无需提 PR):文件放 `~/.opencli/clis/<site>/<name>.js`,无需 build
```bash
# Repo 贡献:build 后直接运行
npm run build
opencli list | grep mysite # 确认注册
opencli mysite mycommand --limit 3 -v # 实际运行
# 私人 adapter(~/.opencli/clis/):一键验证
opencli browser verify <site>/<name>
```
**Done 标准**:命令运行后返回非空表格,且字段符合预期。
