我正在尝试使用cUrl连接到Chrome远程调试,但是Chrome的响应返回“ 200 OK”,但没有数据。
我使用以下方法设置chrome:
chrome.exe --headless --remote-debugging-port=12345
我可以使用以下方法成功获取页面列表:
>curl -i "http://localhost:12345/json"
HTTP/1.1 200 OK
Content-Length:612
Content-Type:application/json; charset=UTF-8
[ {
"description": "",
"devtoolsFrontendUrl": "/devtools/inspector.html?ws=localhost:12345/devtools/page/19d24d3a-25b7-4ee8-a5cf-4f3d17778575",
...
"webSocketDebuggerUrl": "ws://localhost:12345/devtools/page/19d24d3a-25b7-4ee8-a5cf-4f3d17778575"
} ]
但是,我只能从调试器URL获得空的成功响应:
>echo {"id":0,"method":"Page.navigate","params":{"url":"https://stackoverflow.com/"}}|curl -i "http://localhost:12345/devtools/page/19d24d3a-25b7-4ee8-a5cf-4f3d17778575" -H "Content-Type: application/json" -d -
HTTP/1.1 200 OK
Content-Length:0
Content-Type:text/plain
诸如Page.navigate
之类的命令以及格式错误的请求均返回200 OK
,但什么也不执行。
我想念的是什么?
答案 0 :(得分:1)
您需要使用websocket来管理chrome。引用chromedevtools.github.io:
您的应用程序可以通过请求以下内容来发现可用页面: http://localhost:9222/json并获取带有信息的JSON对象 关于可检查页面以及您的WebSocket地址 可以用来开始检测它们
这是它的工作方式(至少在我的Mac上是这样):
docker pull deepsweet/chromium-headless-remote:69
docker run -it --rm -p 9222:9222 deepsweet/chromium-headless-remote:69
curl -i "http://localhost:9222/json"
HTTP/1.1 200 OK
Content-Length:361
Content-Type:application/json; charset=UTF-8
[ {
"description": "",
"devtoolsFrontendUrl": "/devtools/inspector.html?ws=localhost:9222/devtools/page/DC33B65CA373BE2770F2A1031C3B4CBF",
"id": "DC33B65CA373BE2770F2A1031C3B4CBF",
"title": "about:blank",
"type": "page",
"url": "about:blank",
"webSocketDebuggerUrl": "ws://localhost:9222/devtools/page/DC33B65CA373BE2770F2A1031C3B4CBF"
} ]
echo '{ "id":2, "method":"Page.navigate", "params":{"url": "http://www.stackoverflow.com"} }' | websocat -t - ws://localhost:9222/devtools/page/DC33B65CA373BE2770F2A1031C3B4CBF
在示例中使用websocat。您也可以编写一个简单的脚本来完成此操作,例如here
curl -i "http://localhost:9222/json"
HTTP/1.1 200 OK
Content-Length:432
Content-Type:application/json; charset=UTF-8
