我试图实现文件上传到我的WCF服务在ASP.NET的C#文件上传(413)请求实体过大
下面是文件上传在WCF服务器的代码。
public void FileUpload(string fileName, Stream fileStream)
{
FileStream fileToupload = new FileStream("D:\\FileUpload\\" + fileName, FileMode.Create);
// byte[] bytearray = new byte[10000];
byte[] bytearray = new byte[1000];
int bytesRead, totalBytesRead = 0;
do
{
bytesRead = fileStream.Read(bytearray, 0, bytearray.Length);
totalBytesRead += bytesRead;
if(bytesRead > 0)
fileToupload.Write(bytearray, 0, bytearray.Length);
} while (bytesRead > 0);
// fileToupload.Write(bytearray, 0, bytearray.Length);
fileToupload.Close();
fileToupload.Dispose();
}
下面是客户端上传文件的代码:(固定的字节数组大小)
protected void bUpload_Click(object sender, EventArgs e)
{
byte[] bytearray = null;
Stream stream;
string fileName = "";
//throw new NotImplementedException();
if (FileUpload1.HasFile)
{
fileName = FileUpload1.FileName;
stream = FileUpload1.FileContent;
stream.Seek(0, SeekOrigin.Begin);
bytearray = new byte[stream.Length];
int count = 0;
while (count < stream.Length)
{
bytearray[count++] = Convert.ToByte(stream.ReadByte());
}
}
string baseAddress = "http://localhost/WCFService/Service1.svc/FileUpload/";
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(baseAddress + fileName);
request.Method = "POST";
request.ContentType = "text/plain";
Stream serverStream = request.GetRequestStream();
serverStream.Write(bytearray, 0, bytearray.Length);
serverStream.Close();
try
{
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
int statusCode = (int)response.StatusCode;
System.Diagnostics.Debug.WriteLine("statusCode: " + statusCode);
StreamReader reader = new StreamReader(response.GetResponseStream());
System.Diagnostics.Debug.WriteLine("reader: " + reader.ToString());
}
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine("--- EXCEPTION ---");
ex.ToString();
}
}
这是工作好具有体积小文件,当我和大大小的文件试过 我将固定大小的字节数组更改为动态字节数组写入流。 这里是更新的代码:(1024个字节的字节数组数据块用于发送数据)
request.Method = "POST";
request.ContentType = "text/plain";
// Stream serverStream = request.GetRequestStream();
if (FileUpload1.HasFile)
{
fileName = FileUpload1.FileName;
stream = FileUpload1.FileContent;
stream.Seek(0, SeekOrigin.Begin);
bytearray = new byte[1024];//stream.Length];
}
int TbyteCount = 0;
Stream requestStream = request.GetRequestStream();
int bufferSize = 1024;
byte[] buffer = new byte[bufferSize];
int byteCount = 0;
while ((byteCount = stream.Read(buffer, 0, bufferSize)) > 0)
{
TbyteCount = TbyteCount + byteCount;
requestStream.Write(buffer, 0, byteCount);
}
requestStream.Close();
try
{
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
int statusCode = (int)response.StatusCode;
System.Diagnostics.Debug.WriteLine("statusCode: " + statusCode);
StreamReader reader = new StreamReader(response.GetResponseStream());
System.Diagnostics.Debug.WriteLine("reader: " + reader.ToString());
}
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine("--- EXCEPTION ---");
ex.ToString();
}
}
但是在读响应我得到异常 远程服务器返回一个错误:(413)请求实体过大。
我是否正确地在请求流中写入多次!
我使用的文件大小22.4 KB,则使用第一代码(固定大小的数组) 成功上传如果我在1024个字节的倍数分割文件的大小,并试图发送再有一个问题。

感谢您的评论。我使用的文件大小为22.4 KB,使用第一个代码(固定大小的数组)成功上传。如果我将文件大小以1024字节的倍数分割并尝试发送,则会出现问题。 – Ashok
您似乎没有将数据以块的形式发送到服务 - 您正在以块的形式构建流,但是您将它作为一个请求发送。你可以发布你的服务的绑定配置(最好是整个配置的部分)。您可能没有创建特定的绑定,也没有将所述绑定分配给显式端点。 –
