WCF 上传文件远程服务器返回错误：（413）请求实体太大

Question

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。所以我猜你有两个问题：

1. 为什么我传输后文件变大了？
2. 为什么我不能发送更大的文件而不出现此错误？

我的 Web 服务很好，但这里是代码：

[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>
<bindings>
    <basicHttpBinding>
        <binding name="uploadfilebinding" closeTimeout="10:01:00"

              address=""
              binding="basicHttpBinding"
              bindingConfiguration="uploadfilebinding"
              contract="sUploadFile.UploadFile">

        <endpoint

              binding="mexHttpBinding" contract="IMetadataExchange" />

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)
    {
    }

}

Answer 1

改变

byte[] bytearray = new byte[1000000];

到：

byte[] bytearray = new byte[fileSize+1];
