selenium接管方式

1、指定启动参数打开浏览器

# 指定chrome 远程调试接口与用户目录chrome.exe --remote-debugging-port=9222 --user-data-dir="C:\selenum\AutomationProfile"

2selenium接管

self.options = webdriver.ChromeOptions()
self.options.add_experimental_option("debuggerAddress", "127.0.1:9222")
self.chromeDriver = webdriver.Chrome(driverPath, options=self.options)

协议

webdriver协议

使用 DevTools 作为协议客户端

开发者工具前端可以附加到远程运行的 Chrome 实例进行调试。要使此方案正常运行,您应该使用 remote-debugging-port 命令行开关启动您的主机Chrome 实例

chrome.exe --remote-debugging-port=9222

然后,您可以使用不同的用户配置文件启动一个单独的客户端Chrome 实例:

chrome.exe --user-data-dir=<某个目录>

现在,您可以从客户端导航到给定端口并附加到任何发现的选项卡以进行调试:http://localhost:9222

监听协议

这对于理解 DevTools 前端如何使用协议特别方便。您可以在发生时查看所有请求/响应和方法。

协议监视器的屏幕截图

单击 DevTools 右上角的齿轮图标以打开设置面板。选择设置左侧的实验。打开“Protocol Monitor”,然后关闭并重新打开 DevTools。现在单击 ⋮ 菜单图标,选择更多工具,然后选择协议监视器

您还可以使用协议监视器(版本 92.0.4497.0+)发出您自己的命令。如果该命令不需要任何参数,请在“协议监视器”面板底部的提示中键入该命令,然后按 Enter,例如, Page.captureScreenshot。如果命令需要参数,请将它们作为 JSON 提供,例如 {"command":"Page.captureScreenshot","parameters":{"format": "jpeg"}}.

http获取启动信息

GET /json/version

Browser version metadata

{    "Browser": "Chrome/72.0.3601.0",    "Protocol-Version": "1.3",    "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3601.0 Safari/537.36",    "V8-Version": "7.2.233",    "WebKit-Version": "537.36 (@cfede9db1d154de0468cb0538479f34c0755a0f4)",    "webSocketDebuggerUrl": "ws://localhost:9222/devtools/browser/b0b8a4fb-bb17-4359-9533-a8d9f3908bd8"}

GET /json or /json/list

A list of all available websocket targets.

[ {
  "description": "",
  "devtoolsFrontendUrl": "/devtools/inspector.html?ws=localhost:9222/devtools/page/DAB7FB6187B554E10B0BD18821265734",

  "webSocketDebuggerUrl": "ws://localhost:9222/devtools/page/DAB7FB6187B554E10B0BD18821265734"} ]

GET /json/protocol/

The current devtools protocol, as JSON:

{
  "domains": [
      {
          "domain": "Accessibility",
          "experimental": true,
          "dependencies": [
              "DOM"
          ],
          "types": [

                  "enum": [
                      "boolean",
                      "tristate",// ...

GET /json/new?{url}

Opens a new tab. Responds with the websocket target data for the new tab.

GET /json/activate/{targetId}

Brings a page into the foreground (activate a tab).

For valid targets, the response is 200: "Target activated". If the target is invalid, the response is 404: "No such target id: {targetId}"

GET /json/close/{targetId}

Closes the target page identified by targetId.

For valid targets, the response is 200: "Target is closing". If the target is invalid, the response is 404: "No such target id: {targetId}"

WebSocket /devtools/page/{targetId}

The WebSocket endpoint for the protocol.

GET /devtools/inspector.html

A copy of the DevTools frontend that ship with Chrome.

远程调试步骤

1、设置远程调试端口

chrome.exe --remote-debugging-port=9222

2、http获取浏览信息

postman    http://localhost:9222/json/version
{    "Browser": "Chrome/91.0.4472.124",    "Protocol-Version": "1.3",    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36",    "V8-Version": "9.1.269.36",    "WebKit-Version": "537.36 (@7345a6d1bfcaff81162a957e9b7d52649fe2ac38)",    "webSocketDebuggerUrl": "ws://localhost:9222/devtools/browser/325848c7-f588-4b2a-8d53-871d0c407498"}

3、ws执行后续命令示例

# 获取sessionidimport websocketimport jsonws = websocket.create_connection("ws://localhost:9222/devtools/browser/325848c7-f588-4b2a-8d53-871d0c407498")cmd = {"id": 100, "method": "Target.attachToTarget", "params": {"targetId":"C6D11457622705623B8F5381612D197D", "flatten":True}}data = json.dumps(cmd, ensure_ascii=False)ws.send(data)while 1:
    result = ws.recv()
    print(result)

4、event示例

import websocketimport jsonws = websocket.create_connection("ws://localhost:9222/devtools/page/7064B86A54979CA238AABB1784858038")cmd = {"id": 1, "method": "Page.enable", "params": {"windowId": 1, "bounds":{

    result = ws.recv()
    print(result)
