URI格式不受支持。远程服务器返回错误：（401）未经授权。 [英] URI format not supported.the remote server returned an error: (401) unauthorized.

问题描述

Hi,

I want to download the document from below mentioned URL. When i try to download directly in the IE URL, it will be asking username and password credential to open the document.

But, when i try to download through application i am getting below error.

"The remote server returned an error: (401) Unauthorized."

ASP.NET Code:

downloadbutton_click event

URIFile = http://sr1250kl.vrmnet.vrm.intranet/A1/servlet/Download?auth=basic&event_name=k1_view&_file=emparea&id=0000008763&version=01

Dim client As New WebClient()
client.Credentials = CredentialCache.DefaultCredentials
client.UseDefaultCredentials = True
client.Credentials = New NetworkCredential("XXXXXX", "XXXXXXX", "vrmnet.vrm.intranet")
Dim buffer As Byte() = client.DownloadData(URIFile )
Dim download As String = Encoding.ASCII.GetString(buffer)
Console.WriteLine(download)
Console.WriteLine("Download successful.")
Response.ContentType = "application/pdf"
Response.AddHeader("content-length", buffer.Length.ToString())
Response.BinaryWrite(buffer)

The above code is not working when i click the download button using above code. Error : "The remote server returned an error: (401) Unauthorized."

How to download the file..?

我尝试过：



URIFile = http：//sr1250kl.vrmnet.vrm.intranet/A1/servlet/Download？auth = basic& event_name = k1_view& _file = emparea& id = 0000008763& version = 01



Dim client As New WebClient（）

client.Credentials = CredentialCache.DefaultCredentials

client.UseDefaultCredentials =真的

client.Credentials =新的NetworkCredential（XXXXXX，XXXXXXX，vrmnet.vrm.intranet）

Dim buffer As Byte（）= client.DownloadData （URIFile）

昏暗下载As String = Encoding.ASCII.GetString（缓冲区）

Console.WriteLine（下载）

Console.WriteLine（ 下载成功。）

回复。 ContentType =application / pdf

Response.AddHeader（content-length，buffer.Length.ToString（））

Response.BinaryWrite（buffer）

What I have tried:

URIFile = http://sr1250kl.vrmnet.vrm.intranet/A1/servlet/Download?auth=basic&event_name=k1_view&_file=emparea&id=0000008763&version=01

Dim client As New WebClient()
client.Credentials = CredentialCache.DefaultCredentials
client.UseDefaultCredentials = True
client.Credentials = New NetworkCredential("XXXXXX", "XXXXXXX", "vrmnet.vrm.intranet")
Dim buffer As Byte() = client.DownloadData(URIFile )
Dim download As String = Encoding.ASCII.GetString(buffer)
Console.WriteLine(download)
Console.WriteLine("Download successful.")
Response.ContentType = "application/pdf"
Response.AddHeader("content-length", buffer.Length.ToString())
Response.BinaryWrite(buffer)

推荐答案

Finally i did R&D i found the solution.it's very simple code.

Dim fileName As String = grd.DataKeys(gvrow.RowIndex).Values(0).ToString()

ScriptManager.RegisterStartupScript(Me, Page.GetType(), "Open", "window.open('" + fileName + "');", True)
