我到处寻找并尝试了很多修复来解决这个问题，但我很茫然，也许它只是我看不到的东西。我有一个带有 WCF 服务的 ASP.NET 网站，用于上传文件，我可以上传小文件（虽然 16kb 在另一端变成了 977）但是当我上传更大的文件（150kb）时，我得到一个错误远程服务器返回错误：（413）请求实体太大。我增加了可以上传的内容的最大大小，但据我所知，这就是我需要做的一切。所以我想你有两个问题：
- 为什么传输后文件变大了？
- 为什么我不能发送更大的文件而不会出现此错误？
我的 Web 服务很好，但为了它，这里是代码：
[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = "FileUpload/{fileName}")]
void FileUpload(string fileName, Stream fileStream);
public void FileUpload(string fileName, Stream fileStream)
{
FileStream fileToupload = new FileStream("C:\\" + fileName, FileMode.Create);
byte[] bytearray = new byte[1000000];
int bytesRead, totalBytesRead = 0;
do
{
bytesRead = fileStream.Read(bytearray, 0, bytearray.Length);
totalBytesRead += bytesRead;
} while (bytesRead > 0);
fileToupload.Write(bytearray, 0, bytearray.Length);
fileToupload.Close();
fileToupload.Dispose();
}
我的 web.config 文件如下
<system.serviceModel>

我这样称呼它：
string baseServiceAddress = "http://" + Environment.MachineName + ":8000/suploadfile.svc/FileUpload";
ServiceHost host = new ServiceHost(typeof(sUploadFile), new Uri(baseServiceAddress));
host.AddServiceEndpoint(typeof(IsUploadFile), new WebHttpBinding(), "").Behaviors.Add(new WebHttpBehavior());
host.Open();
byte[] bytearray=null ;
string name = "";
//throw new NotImplementedException();
if (FileUpload1.HasFile)
{
name = FileUpload1.FileName;
Stream 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://" + Environment.MachineName + ":8000/suploadfile.svc/FileUpload/";
HttpWebRequest request = (HttpWebRequest) HttpWebRequest.Create(baseAddress+name);
request.Method = "POST";
request.ContentType = "text/plain";
try
{
Stream serverStream = request.GetRequestStream();
serverStream.Write(bytearray, 0, bytearray.Length);
serverStream.Close();
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
int statusCode = (int)response.StatusCode;
StreamReader reader = new StreamReader(response.GetResponseStream());
}
}
catch (Exception ess)
{
}
}
