我正在使用 WCF 在数据库（C#）中上传文件，但出现此错误。远程服务器返回意外响应 (413) 请求实体太大。
IService.cs 中的代码
[OperationContract]
void UploadFile(RemoteFileInfo request);
[MessageContract] 公共类 DownloadRequest { [MessageBodyMember] 公共字符串文件名；}
[MessageContract]
public class RemoteFileInfo : IDisposable
{
[MessageHeader(MustUnderstand = true)]
public string FileName;
[MessageHeader(MustUnderstand = true)]
public int ItemID;
[MessageHeader(MustUnderstand = true)]
public string FileExt;
[MessageBodyMember(Order = 1)]
public System.IO.Stream FileByteStream;
public void Dispose()
{
if (FileByteStream != null)
{
FileByteStream.Close();
FileByteStream = null;
}
}
Service.svc.cs 中的代码
public void UploadFile(RemoteFileInfo request)
{
AttachmentDTO objDTO = new AttachmentDTO();
//FileStream targetStream = null;
Stream stream = request.FileByteStream;
const int bufferLen = 65000;
// byte[] buffer = new byte[bufferLen];
// objDTO.FileData = buffer;
AttachmentBLL objBLL = new AttachmentBLL();
try
{
byte[] readBuffer = new byte[bufferLen];
int totalBytesRead = 0;
int bytesRead;
while ((bytesRead = stream.Read(readBuffer, totalBytesRead, readBuffer.Length - totalBytesRead)) > 0)
{
totalBytesRead += bytesRead;
if (totalBytesRead == readBuffer.Length)
{
int nextByte = stream.ReadByte();
if (nextByte != -1)
{
byte[] temp = new byte[readBuffer.Length * 2];
Buffer.BlockCopy(readBuffer, 0, temp, 0, readBuffer.Length);
Buffer.SetByte(temp, totalBytesRead, (byte)nextByte);
readBuffer = temp;
totalBytesRead++;
}
}
}
byte[] buffer = readBuffer;
if (readBuffer.Length != totalBytesRead)
{
buffer = new byte[totalBytesRead];
Buffer.BlockCopy(readBuffer, 0, buffer, 0, totalBytesRead);
}
objDTO.FileData = buffer;
objDTO.FileName = request.FileName;
objDTO.CreatedDate = DateTime.Now;
objDTO.CreatedBy = "user";
objDTO.IsActive = true;
objDTO.FileExt = request.FileExt;
objBLL.AddAttachment(objDTO);
}
catch (Exception ex)
{
}
}
objBLL.AddAttachment(objDTO); 此方法在业务逻辑文件中。BLL 可以与 DAL 通信，但 DAL 无法与 WCF 服务通信。
This Code is written in page.aspx.cs file.
if (fuAttachment.HasFile)
{
string abs = fuAttachment.PostedFile.FileName;
System.IO.FileInfo fileInfo = new System.IO.FileInfo(fuAttachment.PostedFile.FileName);
MyService.RemoteFileInfo uploadRequestInfo = new MyService.RemoteFileInfo();
using (System.IO.FileStream stream = new System.IO.FileStream(fuAttachment.PostedFile.FileName, System.IO.FileMode.Open, System.IO.FileAccess.Read))
{
uploadRequestInfo.FileName = fuAttachment.FileName;
uploadRequestInfo.Length = fileInfo.Length;
uploadRequestInfo.FileByteStream = fuAttachment.FileContent;
uploadRequestInfo.ItemID = itemId;
uploadRequestInfo.FileExt = fuAttachment.PostedFile.ContentType;
client.UploadFile(uploadRequestInfo.FileExt, uploadRequestInfo.FileName, uploadRequestInfo.ItemID, uploadRequestInfo.FileByteStream);
}
}
