问题描述
我正在尝试使用VbNet从我们公司的网站上下载报告。我有以下代码：
I am trying to download a report off of our company website using VbNet. I have the following code:
Dim hwrequest As Net.HttpWebRequest = Net.HttpWebRequest.Create("https://delph.am.mycompany.com/apps/Reports/ExportDocument11.asp?ID=826&Request=List&OpenType=Edit")
hwrequest.CookieContainer = cookies
hwrequest.Accept = "*/*"
hwrequest.AllowAutoRedirect = False
hwrequest.UserAgent = "http_requester/0.1"
hwrequest.Timeout = 60000
hwrequest.Method = "GET"
Dim hwresponse As Net.HttpWebResponse = hwrequest.GetResponse()
If hwresponse.StatusCode = Net.HttpStatusCode.OK Then
Dim responseStream As IO.StreamReader = _
New IO.StreamReader(hwresponse.GetResponseStream())
responseData = responseStream.ReadToEnd()
End If
但是Response对象只返回
But the Response object just returns
<head><title>Object moved</title></head>
<body><h1>Object Moved</h1>This object may be found <a HREF="/Security/ErrorTrap.asp?
ErrorID=7">here</a>.</body>
和响应的Location标头返回：{X = 46，Y = 46}和我我不确定这意味着什么。
有谁能告诉我我做错了什么？在此先感谢。
and the Location header of the response returns: {X=46,Y=46} and I am not sure what that means.
Can anyone please tell me what I am doing wrong? Thanks in advance.
推荐答案
HttpWebRequest类不会像浏览器那样遵循重定向。您必须获取报告文件的实际URL，而不是您正在使用的URL。您正在检索的是一个重定向到另一个页面的HTML页面。
The HttpWebRequest class will not follow redirects like a browser will. You have to get the actual URL of the report file, not the one you're using. What you're retrieving is a HTML page that redirects to another page.
