我正在尝试使用WebDav添加多个文件。我尝试上传到的目录为空。
我循环遍历这些文件并发送这些文件。
1使用HTTP Put将doc1.txt添加到WebDav服务器--总是成功,即使文件已经在那里。
2使用HTTP Put将doc2.txt添加到WebDav服务器--总是失败,出现409错误。
无论我处理的是什么文件或顺序,它总是在第二个文件上失败。有谁有想法吗?
下面是我使用的方法:
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;
}

这是我犯的一个愚蠢的错误。WebDave文档说,“如果PUT会导致创建一个没有适当作用域的父集合的资源,那么它肯定会失败,并返回409 (冲突)。”
我循环遍历我的文件,并连接文件名,而不是简单地替换文件名。
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++;
}当我把它改成这样的时候,它就起作用了:
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++;
