化零为整WCF(7) - 消息处理(使用消息传输优化机制 - MTOM)
作者:webabcd
介绍
WCF(Windows Communication Foundation) - 消息处理:MTOM(Message Transmission Optimization Mechanism) - 消息传输优化机制。本文以web方式上传大文件为例。
示例
1、服务
IMtom.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;using System.ServiceModel;
using System.IO;namespace WCF.ServiceLib.Message
{
/**//// <summary>
/// IMtom接口
/// </summary>
[ServiceContract]
public inte易做图ce IMtom
{
/**//// <summary>
/// 上传文件
/// </summary>
/// <param name="path">文件目标路径</param>
/// <param name="fileData">文件字节数组</param>
[OperationContract]
void UploadFile(string path, byte[] fileData);
}
}Mtom.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;using System.ServiceModel;
using System.IO;namespace WCF.ServiceLib.Message
{
/**//// <summary>
/// Mtom类
/// </summary>
public class Mtom : IMtom
{
/**//// <summary>
/// 上传文件
/// </summary>
/// <param name="path">文件目标路径</param>
/// <param name="fileData">文件字节数组</param>
public void UploadFile(string path, byte[] fileData)
{
FileStream fs = new FileStream(path, FileMode.Create, FileAccess.Write, FileShare.None);
fs.Write(fileData, 0, fileData.Length);
fs.Flush();
fs.Close();
}
}
}
2、宿主
Mtom.svc
<%@ ServiceHost Language="C#" Debug="true" Service="WCF.ServiceLib.Message.Mtom" %>
Web.config
<?xml version="1.0"?>
<configuration>
<system.serviceModel>
<services>
<!--name - 提供服务的类名-->
<!--behaviorConfiguration - 指定相关的行为配置-->
<service name="WCF.ServiceLib.Message.Mtom" behaviorConfiguration="MessageBehavior">
<!--address - 服务地址-->
<!--binding - 通信方式-->
<!--contract - 服务契约-->
<!--bindingConfiguration - 指定相关的绑定配置-->
<endpoint address="" binding="wsHttpBinding" contract="WCF.ServiceLib.Message.IMtom" bindingConfiguration="MtomBindingConfiguration" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="MessageBehavior">
<!--httpGetEnabled - 使用get方式提供服务-->
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
<bindings>
<wsHttpBinding>
<!--messageEncoding - 指定用 MTOM 还是 Text 对 SOAP 消息编码-->
<!--maxReceivedMessageSize - 在采用此绑定配置的通道上可接收的最大消息大小(单位:字节)-->
<!--receiveTimeout - 在传输引发异常之前可用于完成读取操作的时间间隔-->
<binding name="MtomBindingConfiguration" messageEncoding="Mtom" maxReceivedMessageSize="1073741824" receiveTimeout="00:10:00">
<!--maxArrayLength - 配额控制:允许的最大数组长度-->
<readerQuotas maxArrayLength="1073741824" />
</binding>
</wsHttpBinding>
</bindings>
</system.serviceModel>
</configuration>
3、客户端
Mtom.aspx
<%@ Page Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeFile="Mtom.aspx.cs"
Inherits="Message_Mtom" Title="消息处理(使用消息传输优化机制 - MTOM)" %><asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">

<div>
<ul>
<li>可以指定用 MTOM 还是 Text 对 SOAP 消息编码</li>
<li>抓soap消息的时候可以用tcpTrace</li>
<li>用17,766,901字节大小的文件测试:Text编码(soap大小:31,591,929字节);MTOM编码(soap大小:23,696,066字节)</li>
</ul>
</div>
<div>
源文件:
<asp:FileUpload ID="file" runat="server" />
上传路径:
<asp:TextBox ID="txtDestination" runat="server" Text="C:"></asp:TextBox>
<asp:Button ID="btnUpload" runat="server" Text="上传" OnClick="btnUpload_Click" />
</div>
