WinHTTPRequest.ResponseText 未返回完整的 HTML？
我尝试使用 WinHTTP Request 在 VB.Net 中检索网页（HTTPS 网站），但由于某种原因它只返回部分 HTML，它可以接受的字符数是否有长度限制？如果是这样，我可以获取第 10000 个字符之后的内容吗？
相关代码在这里：
oRequest = New WinHttp.WinHttpRequest
oRequest.Open("GET", sQueryURL, False)
oRequest.SetTimeouts(0, 600000, 0, 0)
oRequest.Send()
If oRequest.Status = "200" Then
Debug.Print(oRequest.ResponseText)
Else
End If
I tried to use WinHTTP Request to retrieve a webpage (HTTPS website) in VB.Net and for some reason it was only returning the partial HTML, is there any length restriction on the number of characters it could take? If so, can I get the content after, say, 10000th character?
The relevant code is here:
oRequest = New WinHttp.WinHttpRequest
oRequest.Open("GET", sQueryURL, False)
oRequest.SetTimeouts(0, 600000, 0, 0)
oRequest.Send()
If oRequest.Status = "200" Then
Debug.Print(oRequest.ResponseText)
Else
End If

我已经有一段时间没有使用WinHttpRequest了，但我相信只要你读到ResponseText，WinHttpRequest就会放弃处理响应。由于您正在认真阅读响应，我猜当您打印 ResponseText 时，完整的响应尚未到达！
我认为您有 2 个选项可以尝试：
WinHttpRequest.WaitForResponse()等待整个响应准备好WinHttpRequest.ResponseStream分块处理响应（您需要将块从字节转换为可读文本）我无法判断您是否使用 VB.Net，但如果您是：请考虑使用 System.Web.HttpRequest。界面几乎相同，您将可以更轻松地找到工作示例和建议。
It's been a while since I've used WinHttpRequest, but I believe as soon as you read ResponseText, WinHttpRequest will abandon processing the response. Since you're diving right in reading the response I'd guess the full response hasn't arrived by the time you print ResponseText!
I think you have 2 options to try:
WinHttpRequest.WaitForResponse()to wait for the entire response to be readyWinHttpRequest.ResponseStreamto process the response in chunks (you'll need to convert the chunks from bytes to readable text)I can't tell if you're using VB.Net, but if you are: consider using System.Web.HttpRequest. The interface is pretty much the same and you will have an easier time finding working examples and advice.
