我正在尝试使用 ChromeWebDriver 和MSXML2.ServerXMLHTTPVBA 打开 Google Chrome 的实例。该代码可以正常打开浏览器的新实例,但是当我尝试向 WebDriver 发送自定义用户数据目录时(存储在D:\Profiles\tdmsoares\Desktop\tmpChromeUserData\User Data其中不起作用:


Private Function SendRequest() As Dictionary
    Dim client As Object
    Set client = CreateObject("MSXML2.ServerXMLHTTP")   'ServerXMLHTTP
    
    client.Open "POST", "http://localhost:9515/session"
    
    client.setRequestHeader "Content-Type", "application/json"
    Dim strJsonRequest As String
    strJsonRequest = 'the comments bellow was made intentionally to show different ways I tried
    'strJsonRequest = "{""capabilities"":{""alwaysMatch:""{""args"":""[--user-data-dir=D:/Profiles/tdmsoares/Desktop/tmpChromeUserData/User Data]""},}""sessionId"":""""}"
    'strJsonRequest = "{""capabilities"":{""args"":""[--user-data-dir=D:\Profiles\tdmsoares\Desktop\tmpChromeUserData\User Data\]""},""sessionId"":""}"
    'strJsonRequest = "{""capabilities"":{},{""desiredCapabilities"":{""args"":""[--user-data-dir=D:\Profiles\tdmsoares\Desktop\tmpChromeUserData\User Data]""},""sessionId"":""""}
    'strJsonRequest = "{""capabilities"":{""userDataDir"":""D:\\Profiles\\tdmsoares\\Desktop\\tmpChromeUserData\\User Data\\]""},""sessionId"":""""}"
    'strJsonRequest = "{""capabilities"":{""goog:chromeOptions:args"":""[--[user-data-dir=D:\\Profiles\\tdmsoares\\Desktop\\tmpChromeUserData\\User Data]""},""sessionId"":""""}

    client.send strJsonRequest

    Do While client.readyState < 4
        DoEvents
    Loop

    Set SendRequest = JsonConverter.ParseJson(client.responseText)
End Function

笔记:

  1. 当试图clientMSXML2.ServerXMLHTTP使用中查看对象的结果时,Debug.print client.responseText我得到:
{"value":{"capabilities":{"acceptInsecureCerts":false,"browserName":"chrome","browserVersion":"91.0.4472.124","chrome":{"chromedriverVersion":"91.0.4472.101 (af52a90bf87030dd1523486a1cd3ae25c5d76c9b-refs/branch-heads/4472@{#1462})","userDataDir":"D:\\Profiles\\tdmsoares\\AppData\\Local\\Temp\\scoped_dir7064_314199858"},"goog:chromeOptions":{"debuggerAddress":"localhost:52688"},"networkConnectionEnabled":false,"pageLoadStrategy":"normal","platformName":"windows","proxy":{},"setWindowRect":true,"strictFileInteractability":false,"timeouts":{"implicit":0,"pageLoad":300000,"script":30000},"unhandledPromptBehavior":"dismiss and notify","webauthn:extension:largeBlob":true,"webauthn:virtualAuthenticators":true},"sessionId":"e29d73791d5eec0dfcf2f51426233979"}}

这意味着 user-data-dir 设置为 Temp 尽管尝试更改它

  1. 我在 W3.org 和https://chromedriver.chromium.org/capabilities上查看 WebDriver 的文档,但现在我还没有找到解决方案

  2. 我没有使用 Selenium(互联网上有很多资源)

对于那些面临同样问题的人:

问题是由于错误的 json 请求。我在再次阅读 W3.org 上的 Webdriver 文档以及 Ish Abb 的这篇很棒的帖子https://dev.to/rookieintraining/understanding-the-selenium-webdriver-o8o时发现了这一点(谢谢!)并在 curl 上测试它然后在 vba 本身上使用 MSXML2.ServerXMLHTTP

对于旨在使用自定义用户数据目录(除了 URL 之外,例如:http://localhost:9515/session)启动 Google Chrome 的新会话请求,json 对象具有(基于对我有用的内容):

{"capabilities":{"firstMatch":[{"goog:chromeOptions":{"args":["user-data-dir=Your path\\\ToCustomProfile"]}}]}}

或者

{"capabilities":{"alwaysMatch":{"goog:chromeOptions":{"args":["user-data-dir=Your path\\\ToCustomProfile"]}}}}

简而言之,我必须考虑它的工作方式不同:

  • user-data-dir它放置时没有双破折号“--”
  • 定义"alwaysMatch": {}""firstMatch":[]记住firstMatch需要括号 [] 中的列表
  • 在 Windows 操作系统中,我们需要在处理文件路径时转义 \
  • user-data-dir根据 Chrome 驱动程序文档,是args其中的成员goog:chromeOptions
