[英]The remote server returned an error: (401) Unauthorized when requesting RestApi data
[英]“The remote server returned an error: (401) Unauthorized” error when trying to upload a file
我發現了很多有關(401)未經授權的錯誤的問題,但是沒有一個問題向我解釋了如何診斷問題。
我創建了一個新的MVC ASP.net應用程序,以了解如何將文件上傳到sharepoint文件夾。 截至目前,我似乎無法將文件從C:\\ testfolder \\ file.txt復制到C:\\ testfolder \\ UploadedFiles
這是我在源文件路徑和目標文件夾中發送位置的方法:
//Flag to indicate whether file was uploaded successfuly or not
bool isUploaded = true;
try
{
// Create a PUT Web request to upload the file.
WebRequest request = WebRequest.Create(targetDocumentLibraryPath);
//Set credentials of the current security context
request.PreAuthenticate = true;
request.UseDefaultCredentials = true;
ICredentials credentials = new NetworkCredential( "Username", "password", "Domain"); //I used my username and password here
request.Credentials = credentials;
//request.Credentials = CredentialCache.DefaultCredentials;
request.Method = "PUT";
// Create buffer to transfer file
byte[] fileBuffer = new byte[1024];
// Write the contents of the local file to the request stream.
using (Stream stream = request.GetRequestStream())
{
//Load the content from local file to stream
using (FileStream fsWorkbook = File.Open(sourceFilePath, FileMode.Open, FileAccess.Read))
{
//Get the start point
int startBuffer = fsWorkbook.Read(fileBuffer, 0, fileBuffer.Length);
for (int i = startBuffer; i > 0; i = fsWorkbook.Read(fileBuffer, 0, fileBuffer.Length))
{
stream.Write(fileBuffer, 0, i);
}
}
}
// Perform the PUT request
WebResponse response = request.GetResponse();
//Close response
response.Close();
}
catch (Exception ex)
{
//Set the flag to indiacte failure in uploading
isUploaded = false; //The remote server returned an error: (401) Unauthorized.
}
//Return the final upload status
return isUploaded;
}
我嘗試了以下方法:
關於如何解決此問題的任何想法嗎? 任何對如何調試問題的准見解也將受到贊賞。
更新:可能是我的帳戶被設置為IIS中的應用程序池帳戶。 我仍然不確定是什么問題。
這不會像代理設置那樣嗎?
您是否需要將默認代理設置添加到您的
WebRequest
還需要添加
<system.net>
<defaultProxy useDefaultCredentials="true" />
</system.net>
到您的網絡配置?
這可能會有所幫助。
我決定嘗試另一種方法,並使用此處描述的httpposted文件和.saveAs()
