## Summary
Adds six enterprise due-diligence data-source skills as local built-in
skills (SKILL.md + SKILL.zh-CN.md + catalog-metadata sidecar), per
ADR-038.
| Skill | Category | Risk | Source |
|---|---|---|---|
| baidu-poi-search | data | low | Baidu Map Place API (REST) |
| tianyancha-risk | business | low | Tianyancha risk API (REST) |
| ccgp-gov-procurement | business | medium | ccgp.gov.cn (WebBridge) |
| cnipa-patent-search | business | medium | CNIPA pss-system (WebBridge)
|
| creditchina-query | business | high | creditchina.gov.cn (WebBridge +
ddddocr) |

WebSearch |
## Changes
- 6 x skills/<id>/{SKILL.md, SKILL.zh-CN.md, catalog-metadata.v1.json}
- builtin-skills.json: 34 -> 40
- manifest.json: totalSkills 63 -> 69
- README.md counts + list
## Security
- Credentials replaced with env-var placeholders (BAIDU_MAP_AK,
TIANYANCHA_TOKEN); verified no secrets in diff
## Validation
- validate-i18n.py: 0 errors (remaining warnings pre-existing repo-wide)
- zh/en heading parity verified; source_hash computed per repo algorithm

# 信用中国查询
|
||||
|
||||
## L0
|
||||
|
||||
输入企业名称,通过 Kimi WebBridge 浏览器自动化 + ddddocr 本地 OCR 自动过图形验证码,返回企业信用信息。
|
||||
|
||||
## L1 概述
|
||||
|
||||
- **数据源**:信用中国(`creditchina.gov.cn`,国家发改委指导)
|
||||
- **认证**:图形验证码(ddddocr 本地 OCR 自动识别,~100ms)
|
||||
- **调用方式**:Kimi WebBridge + CDP 截图 + ddddocr Python OCR
|
||||
- **前置条件**:
|
||||
- Kimi WebBridge daemon 运行中
|
||||
- Python 已安装 `ddddocr`(`pip install ddddocr`)
|
||||
- Python 已安装 `Pillow`(`pip install pillow`)
|
||||
|
||||
## L2 操作步骤
|
||||
|
||||
### 1. 导航搜索页
|
||||
|
||||
写入 `C:\tmp\cc-nav.json`:
|
||||
|
||||
```json
|
||||
{
|
||||
"action": "navigate",
|
||||
"args": {
|
||||
"url": "https://www.creditchina.gov.cn/xinyongxinxi/?keyword={企业名称URL编码}&scenesVal=default&tableName=credit_xyzx_tyshxydm",
|
||||
"newTab": true,
|
||||
"group_title": "信用中国查询"
|
||||
},
|
||||
"session": "creditchina-query"
|
||||
}
|
||||
```
|
||||
|
||||
```bash
|
||||
curl.exe -s -X POST "http://127.0.0.1:10086/command" \
|
||||
-H "Content-Type: application/json" \
|
||||
--data-binary "@C:\tmp\cc-nav.json" --max-time 30
|
||||
```
|
||||
|
||||
等待 6 秒。
|
||||
|
||||
### 2. 确认验证码弹层
|
||||
|
||||
写入 `C:\tmp\cc-check.json`:
|
||||
|
||||
```json
|
||||
{
|
||||
"action": "evaluate",
|
||||
"args": {
|
||||
"code": "(function(){var v=document.getElementById('vcode');var i=document.getElementById('vcodeimg');return JSON.stringify({vcode:v?v.getBoundingClientRect().width>0:false,vimg:i?i.getBoundingClientRect().width>0:false});})()"
|
||||
},
|
||||
"session": "creditchina-query"
|
||||
}
|
||||
```
|
||||
|
||||
若 `vcode=true` 且 `vimg=true`,验证码弹层已出现,继续下一步。
|
||||
|
||||
### 3. 获取验证码图坐标
|
||||
|
||||
写入 `C:\tmp\cc-coord.json`:
|
||||
|
||||
```json
|
||||
{
|
||||
"action": "evaluate",
|
||||
"args": {
|
||||
"code": "(function(){var img=document.getElementById('vcodeimg');if(!img)return 'no-img';var r=img.getBoundingClientRect();return JSON.stringify({x:Math.round(r.x),y:Math.round(r.y),w:Math.round(r.width),h:Math.round(r.height),dpr:window.devicePixelRatio});})()"
|
||||
},
|
||||
"session": "creditchina-query"
|
||||
}
|
||||
```
|
||||
|
||||
记录返回的 `x` / `y` / `w` / `h`。
|
||||
|
||||
### 4. CDP 截图验证码区域
|
||||
|
||||
> **注意**:WebBridge 的 screenshot 工具对此页面存在间歇性失败(HTTP 000/400),**必须用 CDP `Page.captureScreenshot` 的 clip 参数**。
|
||||
|
||||
写入 `C:\tmp\cc-shot.json`(替换 `{x}` / `{y}` / `{w}` / `{h}` 为上一步返回值):
|
||||
|
||||
```json
|
||||
{
|
||||
"action": "cdp",
|
||||
"args": {
|
||||
"method": "Page.captureScreenshot",
|
||||
"params": {
|
||||
"format": "png",
|
||||
"clip": { "x": {x}, "y": {y}, "width": {w}, "height": {h}, "scale": 1 }
|
||||
}
|
||||
},
|
||||
"session": "creditchina-query"
|
||||
}
|
||||
```
|
||||
|
||||
```bash
|
||||
curl.exe -s -X POST "http://127.0.0.1:10086/command" \
|
||||
-H "Content-Type: application/json" \
|
||||
--data-binary "@C:\tmp\cc-shot.json" --max-time 40 -o "C:/tmp/cc-cdp-resp.json"
|
||||
```
|
||||
|
||||
解码 base64 并保存为图片:
|
||||
|
||||
```python
|
||||
import json, base64
|
||||
d = json.load(open(r'C:\tmp\cc-cdp-resp.json', encoding='utf-8'))
|
||||
b64 = d.get('data', {}).get('data', '')
|
||||
open(r'C:\tmp\cc-captcha.png', 'wb').write(base64.b64decode(b64))
|
||||
```
|
||||
|
||||
### 5. ddddocr 识别(~100ms)
|
||||
|
||||
```python
|
||||
import ddddocr, sys, time
|
||||
sys.stdout.reconfigure(encoding='utf-8')
|
||||
ocr = ddddocr.DdddOcr(show_ad=False)
|
||||
t0 = time.time()
|
||||
with open(r'C:\tmp\cc-captcha.png', 'rb') as f:
|
||||
code = ocr.classification(f.read())
|
||||
print(f'验证码: {code} ({(time.time()-t0)*1000:.0f}ms)')
|
||||
open(r'C:\tmp\cc-code.txt', 'w').write(code)
|
||||
```
|
||||
|
||||
### 6. 填入验证码 + 点击验证
|
||||
|
||||
写入 `C:\tmp\cc-submit.json`(替换 `{code}` 为识别结果):
|
||||
|
||||
```json
|
||||
{
|
||||
"action": "evaluate",
|
||||
"args": {
|
||||
"code": "(function(){var inp=document.getElementById('vcode');if(!inp)return 'no-input';var s=Object.getOwnPropertyDescriptor(window.HTMLInputElement.prototype,'value').set;s.call(inp,'{code}');inp.dispatchEvent(new Event('input',{bubbles:true}));inp.dispatchEvent(new Event('change',{bubbles:true}));for(var el of document.querySelectorAll('button, a, input[type=button]')){if((el.innerText||el.value||'').trim()==='验证'){el.click();break;}}return 'submitted';})()"
|
||||
},
|
||||
"session": "creditchina-query"
|
||||
}
|
||||
```
|
||||
|
||||
等待 5 秒。
|
||||
|
||||
### 7. 检查验证结果
|
||||
|
||||
写入 `C:\tmp\cc-result.json`:
|
||||
|
||||
```json
|
||||
{
|
||||
"action": "evaluate",
|
||||
"args": {
|
||||
"code": "(function(){var t=document.body.innerText||'';if(t.includes('验证码错误'))return '验证码错误';if(t.includes('失效'))return '验证码已失效';return JSON.stringify({hasResult:t.includes('共')||t.includes('条'),textSample:t.slice(0,500)});})()"
|
||||
},
|
||||
"session": "creditchina-query"
|
||||
}
|
||||
```
|
||||
|
||||
**三种结果**:
|
||||
|
||||
- `"验证码错误"` / `"验证码已失效"` → 返回步骤 3 重试(点"换一张"刷新验证码)
|
||||
- `hasResult=true` 且返回搜索数据 → 成功,继续步骤 8
|
||||
- `textSample` 含"很抱歉,没有找到您搜索的数据" → 验证码已通过,但搜索词无匹配(非技术错误)——建议换企业全名或简称重试
|
||||
|
||||
### 8. 读取搜索结果
|
||||
|
||||
```json
|
||||
{
|
||||
"action": "evaluate",
|
||||
"args": {
|
||||
"code": "(function(){return document.body.innerText.slice(0,1500);})()"
|
||||
},
|
||||
"session": "creditchina-query"
|
||||
}
|
||||
```
|
||||
|
||||
### 9. 标准化映射
|
||||
|
||||
```json
|
||||
{
|
||||
"query_status": "success",
|
||||
"source": "creditchina",
|
||||
"company_name": "{企业名称}",
|
||||
"captcha_solved": true,
|
||||
"search_result": "有结果 | 无匹配",
|
||||
"credit_info": [
|
||||
{
|
||||
"event_type": "行政处罚 | 行政许可 | 失信被执行 | 守信激励",
|
||||
"event_title": "...",
|
||||
"event_date": "...",
|
||||
"source_url": "...",
|
||||
"summary": "..."
|
||||
}
|
||||
],
|
||||
"timestamp": "2026-08-31T21:00:00+08:00"
|
||||
}
|
||||
```
|
||||
|
||||
### 10. 关闭会话
|
||||
|
||||
```json
|
||||
{
|
||||
"action": "close_session",
|
||||
"session": "creditchina-query"
|
||||
}
|
||||
```
|
||||
|
||||
## 重试策略
|
||||
|
||||
验证码识别失败(错误/失效)时自动重试,最多 3 轮:
|
||||
|
||||
1. 点击"换一张"刷新验证码:`evaluate` 点击文本含"换一张"的元素
|
||||
2. 等 2 秒(新图加载)
|
||||
3. 重复步骤 3-6(重新截图→识别→提交)
|
||||
|
||||
3 轮失败后:报告用户,请人工在浏览器中手动过一次验证码,然后智能体接管继续(验证通过后浏览器记住验证态,后续查询免验证码)。
|
||||
|
||||
## 已知限制
|
||||
|
||||
- **验证码时效极短**:从截图到提交需 <15 秒——**必须用 ddddocr 本地识别(~100ms),禁用云端 OCR(10~30 秒往返必超时)**
|
||||
- **CDP 截图替代 screenshot**:WebBridge screenshot 工具对此页面间歇性失败(HTTP 000/400),必须用 CDP `Page.captureScreenshot` 的 clip 参数
|
||||
- **验证态缓存**:一次验证通过后,浏览器记住验证态——后续搜索(导航到新 keyword URL)不再需要验证码,直接返回结果
|
||||
- **CORS 限制**:不能通过 `fetch+FileReader` 或 `canvas.toDataURL` 取图(跨子域 tainted)——只能用 CDP 截图
|
||||
- **搜索词建议**:精确企业全名可能"没有找到您搜索的数据"(信用库只收录有信用记录的主体)——先试全名,无结果再试简称
|
||||
|
||||
## 故障排查
|
||||
|
||||
| 问题 | 原因 | 处理 |
|
||||
|---|---|---|
|
||||
| 412(直连被 WAF 拦截) | 未用浏览器 | 必须通过 WebBridge 浏览器访问 |
|
||||
| 验证码弹层未出现 | keyword 参数未触发 | 检查 URL 中的 keyword 参数 |
|
||||
| CDP 截图返回空 | 坐标错误 / 页面滚动 | 重新获取 vcodeimg 的 getBoundingClientRect |
|
||||
| ddddocr 识别为空 | 图片损坏 / 识别失败 | 刷新验证码重试;确认 CDP 截图 bytes > 3000 |
|
||||
| 验证码错误/失效 | 识别错 / 超时 | 点"换一张"重试(最多 3 轮);仍失败转人工 |
|
||||
| "没有找到您搜索的数据" | 企业无信用记录 / 词不匹配 | 换简称重试;确认企业有信用记录 |
