我對WCF服務很陌生，當上傳的文件太大而無法上傳時，我遇到了這個已知問題。我的情況很奇怪，因爲我同時設置了maxAllowedContentLength和maxRequestLength，因此它應該沒有上傳300 MB文件的問題......對於小文件，它完美地工作，所以對我來說似乎只是忘記了關於我的設置。我嘗試了很多想法來解決這個問題，所以也許我在配置文件中搞砸了一些東西，可能會有一些不必要的部分，但我仍然找不到解決方案。WCF服務 - 404.13錯誤 - 儘管maxAllowedContentLength和maxRequestLength設置爲
我正在使用IIS 10和.Net 4.5。
我的WCF服務配置：

從我的ASP.NET Web應用程序，如該服務引用的web.config文件。
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_ITileService"/>

</bindings>
<client>

</client>
我上傳的方法是這樣實現的：
public void UploadFile(FileUploadMessage request)
{
string basePath = AppDomain.CurrentDomain.BaseDirectory + @"\Images\";
string serverFileName = Path.Combine(basePath, request.Filename);
using (FileStream outfile = new FileStream(serverFileName, FileMode.Create))
{
const int bufferSize = 65536; // 64K
Byte[] buffer = new Byte[bufferSize];
int bytesRead = request.FileByteStream.Read(buffer, 0, bufferSize);
while (bytesRead > 0)
{
outfile.Write(buffer, 0, bytesRead);
bytesRead = request.FileByteStream.Read(buffer, 0, bufferSize);
}
}
}
哪裏FileUploadMessage是這樣的：
[MessageContract]
public class FileUploadMessage
{
[MessageHeader(MustUnderstand = true)]
public string Filename;
[MessageBodyMember(Order = 1)]
public Stream FileByteStream;
}
編輯1：
我發現這篇文章是關於這個問題的。也許我的問題不是與WCF服務或配置，但與IIS？
我將默認應用程序池的requestLimits也設置爲1000000000.錯誤仍然出現。
同樣在選項3中，本文將介紹如何更改ApplicationHost.config。奇怪的是我沒有關於requestLimits的文件。也許這是主要問題？
確保您已安裝IIS請求過濾模塊。或者嘗試重新安裝它。 （轉到添加刪除Windows功能 - >萬維網服務 - >安全 - >請求過濾）。這將添加模塊，它應該更新applicationhost文件。 – Dhanuka777
