各位大神,遇到个问题,几天了解决不了愁得我吃不下饭睡不了觉呀···

wcf上传文件,一超过48k就是400 bad request

以下为代码:

namespace WcfService1
{
   [ServiceContract]
    public interface IService1
        {
            [OperationContract]
            void UploadFile(FileData file);
        }
    
      [MessageContract]
        public class FileData
        {
            [MessageHeader]
            public string filename;
            [MessageBodyMember]
            public Stream data;
        }
}

 

namespace WcfService1 {     // 注意: 使用“重构”菜单上的“重命名”命令,可以同时更改代码、svc 和配置文件中的类名“Service1”。     public class Service1 : IService1     {

        public void UploadFile(FileData file)         {             FileStream fs = new FileStream(@"C:\"+file.filename, FileMode.OpenOrCreate);             try             {

                BinaryReader reader = new BinaryReader(file.data);                 byte[] buffer;                 BinaryWriter writer = new BinaryWriter(fs);                 long offset = fs.Length;                 writer.Seek((int)offset, SeekOrigin.Begin);                 do                 {                     buffer = reader.ReadBytes(1024);

                    writer.Write(buffer);

                } while (buffer.Length > 0);             }             catch (Exception e)             {

            }             finally             {

                fs.Close();                 file.data.Close();

            }         }     } }

 

 

apconfig:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.serviceModel>
        <services>
            <service name="WcfService1.Service1">
                <endpoint address="http://localhost:51094/Service1.svc" binding="basicHttpBinding"
                    bindingConfiguration="LargeDataTransferServicesBinding" contract="WcfService1.IService1" />
            </service>
        </services>
      <bindings>
        <basicHttpBinding>
          <binding name="LargeDataTransferServicesBinding" maxReceivedMessageSize="2147483647" messageEncoding="Mtom" transferMode="Streamed" sendTimeout="00:10:00">
            <readerQuotas maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxDepth="2147483647" maxNameTableCharCount="2147483647" maxStringContentLength="2147483647"/>
          </binding>
        </basicHttpBinding>
      </bindings>
    </system.serviceModel>
</configuration>

 

客户端:

namespace WebApplication8 {     public partial class _Default : System.Web.UI.Page     {

        protected void Button1_Click(object sender, EventArgs e)         {           ServiceReference1.Service1Client service = new ServiceReference1.Service1Client();             service.UploadFile(FileUpload1.PostedFile.FileName, FileUpload1.FileContent);         }     } }

 

 

webconfig:

  <system.serviceModel>     <bindings>       <basicHttpBinding>

        <binding name="BasicHttpBinding_IService1" maxBufferSize="2147483647"  messageEncoding="Mtom" transferMode="Streamed" maxReceivedMessageSize="2147483647">           <readerQuotas maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxDepth="2147483647" maxNameTableCharCount="2147483647" maxStringContentLength="2147483647"/>           <security mode="None" />         </binding>

      </basicHttpBinding>     </bindings>     <client>       <endpoint address="http://localhost:51094/Service1.svc" binding="basicHttpBinding"         bindingConfiguration="BasicHttpBinding_IService1" contract="ServiceReference1.IService1"         name="BasicHttpBinding_IService1" />     </client>   </system.serviceModel>

拜托你格式化下代码,这样的代码看起来很累,知道吗?

另外说明下你的网络条件,传输48K文件所用的时间留意下,是不是正好1分种,有个一分钟超时设置的。还有就是网络是否丢包,如果会丢包,文件大了也会导致失败。

我记得应该是64KB的限制啊,可以用流来传送大文件。

需要注意你的Server端和Client端的包大小设置要一样,如果不一样会出现400 Bad Request的问题
