在与 ChromeDriver 和 MSXML2 交互时发送自定义用户数据目录.ServerXMLHTTP (VBA).



我正在尝试使用ChromeWebDriver打开Google Chrome的实例,并在VBA上MSXML2.ServerXMLHTTP。代码可以很好地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(存储在D:ProfilestdmsoaresDesktoptmpChromeUserDataUser Data中时,它不起作用:


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:ProfilestdmsoaresDesktoptmpChromeUserDataUser Data]""},""sessionId"":""}"
'strJsonRequest = "{""capabilities"":{},{""desiredCapabilities"":{""args"":""[--user-data-dir=D:ProfilestdmsoaresDesktoptmpChromeUserDataUser 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. 当尝试使用Debug.print client.responseText查看对象client的结果时MSXML2.ServerXMLHTTP,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"}}

这意味着用户数据目录设置为Temp,尽管试图更改此内容

  1. 我在 W3.org 和 https://chromedriver.chromium.org/capabilities 查看了WebDriver的文档,但现在我仍然没有找到解决方案

  2. 我没有使用硒(互联网上有很多资源)

对于那些面临相同问题的人:

问题是由于错误的 json 请求造成的。我在再次阅读 W3.org 的 Web 驱动程序文档以及 Ish Abb https://dev.to/rookieintraining/understanding-the-selenium-webdriver-o8o 的这篇很棒的帖子时想通了(谢谢!),并在 curl 上测试它,然后在 vba 本身上使用 MSXML2 对其进行测试。服务器XMLHTTP

对于旨在使用自定义用户数据目录启动谷歌浏览器的新会话请求(除了网址之外,例如:http://localhost:9515/session),json 对象具有(基于对我有用的):

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

{"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放置时没有双破折号"--">
  • 定义"alwaysMatch": {}""firstMatch":[]记住firstMatch需要括号中的列表 []
  • 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的成员,是goog:chromeOptions的成员
