使用chromedrive可执行文件

这适用于我(Windows+Postman)，但也应该适用于Curl Linux/Mac。

• 1下载您的Chrome版本的chromeDriver：https://chromedriver.chromium.org/downloads。*
• 2启动chromeDriver*

start chromedriver.exe

输出：

Starting ChromeDriver 97.0.4692.71 on port 9515...

• 3向本地主机发送请求：9515/*
• 3.1创建会话：

POST localhost:9515/session

request json body:
{"capabilities":{"goog:chromeOptions": {}}}

status 200

response:
 "value": {
        "capabilities": {
            ...
        },
        "sessionId": "b8ac49ce2203739fa0d32dfe8d1a23b5"

• 3.2导航一些url(可选，只需根据会话ID检查请求即可)：

POST localhost:9515/session/b8ac49ce2203739fa0d32dfe8d1a23b5/url

request json body:
{"url": "https://example.com"}

status 200

• 3.3执行CDP命令(截图)：

POST localhost:9515/session/b8ac49ce2203739fa0d32dfe8d1a23b5/goog/cdp/execute

request json body:
{"cmd":"Page.captureScreenshot", "params":{}}

status 200

response:
{
    "value": {
        "data": "iVBORw0KGgoAAAANSUhEUgA...."
    }
}

允许远程连接

默认情况下，chromeDriver仅允许本地连接。
允许某些远程IP的步骤：

start chromedriver.exe --allowed-ips="some-remote-ip"

使用Selify Grid运行CDP命令

最终，它开始对我起作用，

• ChromeDriver 97.0.4692.71
• Selify-SERVER-4.1.1
• Chrome 97.0.4692.71(官方版本)(64位)

注意：对于Selify Grid HTTP请求，Content-Type标头应该具有charset=utf-8 Content-Type:application/json;charset=utf-8。

前提条件

• 1根据*https://www.selenium.dev/documentation/grid/getting_started/下载并运行Selify服务器

java -jar selenium-server-<version>.jar standalone --driver-configuration display-name='Chrome' stereotype='{"browserName":"chrome"}'

• 2创建会话：*

POST localhost:4444/wd/hub/session

request json body:
{
  "desiredCapabilities": {
    "browserName": "chrome",
    "goog:chromeOptions": {
      "args": [
      ],
      "extensions": [
      ]
    }
  },
  "capabilities": {
    "firstMatch": [
      {
        "browserName": "chrome",
        "goog:chromeOptions": {
          "args": [
          ],
          "extensions": [
          ]
        }
      }
    ]
  }
}

status 200

response:
{
    "status": 0,
    "sessionId": "69ac1c82306f72c7aaf53cfbb28a30e7",
    ...
    }
}

• 3执行CDP命令(截图)：*

POST localhost:4444/wd/hub/session/69ac1c82306f72c7aaf53cfbb28a30e7/goog/cdp/execute

request json body:
{"cmd":"Page.captureScreenshot", "params":{}}

status 200

response:
{
    "value": {
        "data": "iVBORw0KGgoAAAANSUhEUgA...."
    }
}
