Navigate to the search page Write `C:\tmp\cc-nav.json`: ```json { "action": "navigate", "args": { "url": "https://www.creditchina.gov.cn/xinyongxinxi/?keyword={company-name-URL-encoded}&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 ``` Wait 6 seconds. ### 2. Confirm the captcha overlay Write `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" } ``` If `vcode=true` and `vimg=true`, the captcha overlay is visible — continue. ### 3. Get the captcha image coordinates Write `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" } ``` Record `x` / `y` / `w` / `h`. ### 4. CDP screenshot of the captcha region > **Note**: the WebBridge screenshot action fails intermittently on this site (HTTP 000/400) — **always use CDP `Page.captureScreenshot` with the clip parameter**. Write `C:\tmp\cc-shot.json` (replace `{x}` / `{y}` / `{w}` / `{h}`): ```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" ``` Decode the base64 payload and save the image: ```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 recognition (~100 ms) ```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. Fill and submit the captcha Write `C:\tmp\cc-submit.json` (replace `{code}`): ```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" } ``` Wait 5 seconds. ### 7. Check the verification result Write `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" } ``` **Three outcomes**: - `"验证码错误"` / `"验证码已失效"` → retry from step 3 (click 换一张 to refresh) - `hasResult=true` with data → success, go to step 8 - `textSample` contains "很抱歉，没有找到您搜索的数据" → captcha passed but the keyword has no match — retry with the full name or a short name ### 8. Read the search results ```json { "action": "evaluate", "args": { "code": "(function(){return document.body.innerText.slice(0,1500);})()" }, "session": "creditchina-query" } ``` ### 9. Normalized mapping ```json { "query_status": "success", "source": "creditchina", "company_name": "{company name}", "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. Close the session ```json { "action": "close_session", "session": "creditchina-query" } ``` ## Retry Strategy On captcha failure (wrong/expired), retry automatically up to 3 rounds: 1. Click 换一张 to refresh the captcha via `evaluate` 2. Wait 2 seconds for the new image 3. Repeat steps 3-6 (screenshot → recognize → submit) After 3 failed rounds: ask the user to solve the captcha manually once in the browser, then resume — once verified, the browser remembers the state and subsequent queries skip the captcha. ## Known Limitations - **Very short captcha TTL**: screenshot-to-submit must stay under ~15 s — **use ddddocr locally (~100 ms); cloud OCR (10-30 s round trips) always times out** - **CDP screenshot required**: the WebBridge screenshot action fails intermittently here; use CDP `Page.captureScreenshot` with clip - **Verification caching**: once passed, subsequent searches (navigating to new keyword URLs) return results without another captcha - **CORS**: `fetch+FileReader` or `canvas.toDataURL` cannot capture the image (cross-origin taint) — CDP screenshots only - **Keyword advice**: exact full names may return "no data" (the database only covers entities with credit records) — try the full name first, then the short name ## Troubleshooting | Problem | Cause | Fix | |---|---|---| | 412 on direct HTTP | WAF blocks non-browser calls | always go through WebBridge | | Captcha overlay missing | keyword param not triggered | check the keyword in the URL | | Empty CDP screenshot | wrong coordinates / scrolled page | re-read `vcodeimg` bounding rect | | ddddocr returns empty | broken image / recognition failure | refresh and retry; confirm screenshot bytes > 3000 | | Wrong/expired captcha | misread / timeout | refresh (up to 3 rounds); fall back to manual | | "没有找到您搜索的数据" | no credit records / keyword mismatch | retry with the short name |
