我正在尝试使用 WebDav 添加多个文件。我试图上传到的目录是空的。
我遍历文件并发送文件。
1 使用 HTTP Put 将 doc1.txt 添加到 WebDav 服务器 - 即使文件已经存在,也总是成功。
2 使用 HTTP Put 将 doc2.txt 添加到 WebDav 服务器 - 始终失败并显示 409 错误。
我处理文件的文件或顺序无关紧要,它总是在第二个文件上失败。任何人有和想法?
这是我正在使用的方法:
public static bool UploadFile(string url, string filePath)
{
if (!File.Exists(filePath))
{
return false;
}
long fileLen = new FileInfo(filePath).Length;
HttpWebRequest Request = (HttpWebRequest)HttpWebRequest.Create(url);
Request.Credentials = mCredentials;
Request.Method = WebRequestMethods.Http.Put;
Request.ContentLength = fileLen;
Request.SendChunked = true;
// Specify that overwriting the destination is allowed.
Request.Headers.Add(@"Overwrite", @"T");
Request.AllowWriteStreamBuffering = true;
System.IO.Stream stream = Request.GetRequestStream();
FileStream fileStrem = new FileStream(filePath, FileMode.Open, FileAccess.Read);
int transferRate = 4096;
byte[] data = new byte[transferRate];
int read = 0;
long totalRead = 0;
try
{
do
{
read = fileStrem.Read(data, 0, data.Length);
if (read > 0)
{
totalRead += read;
stream.Write(data, 0, read);
}
} while (read > 0);
}
catch (Exception ex)
{
throw ex;
}
finally
{
stream.Close();
stream.Dispose();
stream = null;
fileStrem.Close();
fileStrem.Dispose();
fileStrem = null;
}
HttpWebResponse Response;
try
{
Response = (HttpWebResponse)Request.GetResponse();
}
catch (WebException e)
{
if (e.Response == null)
{
Debug.WriteLine("Error accessing Url " + url);
throw;
}
HttpWebResponse errorResponse = (HttpWebResponse)e.Response;
//if the file has not been modified
if (errorResponse.StatusCode == HttpStatusCode.NotModified)
{
e.Response.Close();
return false;
}
else
{
e.Response.Close();
Debug.WriteLine("Error accessing Url " + url);
throw;
}
}
//This case happens if no lastmodedate was specified, but the specified
//file does exist on the server.
Response.Close();
if (totalRead == fileLen)
{
return true;
}
else
{
return false;
}
}

这对我来说是一个愚蠢的错误。WebDave 文档说,“将导致创建没有适当范围的父集合的资源的 PUT 必须以 409(冲突)失败。”。
好吧,我正在遍历我的文件并连接文件名,而不是仅仅替换文件名。
这就是我调用 UploadFile 的方式:
string url = "http://someurl"
foreach (string file in files)
{
url = url.TrimEnd(new char[] { '/' }) + @"/" + System.IO.Path.GetFileName(file);
UploadFile(url, file);
fileCount++;
}

当我将其更改为此时,它可以工作:
string url = "http://someurl"
string temp;
foreach (string file in files)
{
temp = url.TrimEnd(new char[] { '/' }) + @"/" + System.IO.Path.GetFileName(file);
UploadFile(temp, file);
fileCount++;
}
