本文介绍了在控制台中托管简单的Wcf服务的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我试图创建一个简单的ConsoleApplication，其中我想主持一个简单的wcf服务。



这是我的代码

 命名空间HostConsoleApplication 
 {
 class Program 
 {
 static void Main（string [] args）
 {
 using（System.ServiceModel.ServiceHost host = new System.ServiceModel.ServiceHost（typeof（FirstWcfService.Service）））
 {
 host.Open（）; 
 Console.WriteLine（Sai）; 
 Console.ReadLine（）; 
} 
} 
} 
}

我添加了一个app.config，看起来像这样：

 <？xml version =1.0encoding =utf- 8→> 
< configuration> 
< system.serviceModel> 
< services> 
< service name =FirstWcfService.ServicebehaviorConfiguration =ServiceBehavior> 
< endpoint address =FirstWcfServicebinding =netTcpBindingcontract =FirstWcfService.IService/> 
< endpoint contract =IMetadataExchangebinding =mexHttpBindingaddress =mex/> 
< host> 
< baseAddresses> 
< add baseAddress =net.tcp：// localhost：9101 //> 
< / baseAddresses> 
< / host> 
< / service> 
< / services> 
< behaviors> 
< serviceBehaviors> 
< behavior name =ServiceBehavior> 
< serviceMetadata httpGetEnabled =false/> 
< / behavior> 
< / serviceBehaviors> 
< / behaviors> 
< /system.serviceModel> 
< / configuration>

当我运行主机控制台应用程序时，我得到这个异常：


System.InvalidOperationException是
unhandled Message =对于绑定$ b的端点，找不到与方案http
匹配的
基本地址$ b MetadataExchangeHttpBinding。
注册的基地址方案是
[net.tcp]。

解决方案

好吧，我想问题是这样：




  • 您有net.tcp

  • 的基地址定义了一个MEX http端点（但没有http基地址）



基本上，如果您想通过http使用MEX，则需要为 MEX端点或http基地址（如果只指定相对地址）。



解决方案1：指定MEX的完整地址端点：

 < services> 
< service name =FirstWcfService.Service
 behaviorConfiguration =ServiceBehavior> 
< endpoint 
 address =FirstWcfService
 binding =netTcpBinding
 contract =FirstWcfService.IService/> 
< endpoint 
 address =http：// localhost：9102 / FirstWcfService / mex
 binding =mexHttpBinding
 contract =IMetadataExchange/& 
 ...... 
< / service> 
< / services>解决方案2：也定义一个HTTP基地址：
 
 < services> 
< service name =FirstWcfService.Service
 behaviorConfiguration =ServiceBehavior> 
< endpoint 
 address =FirstWcfService
 binding =netTcpBinding
 contract =FirstWcfService.IService/> 
< endpoint 
 address =mex
 binding =mexHttpBinding
 contract =IMetadataExchange/& 
< host> 
< baseAddresses> 
< add baseAddress =net.tcp：// localhost：9101 //> 
< add baseAddress =http：// localhost：9102 //> 
< / baseAddresses> 
< / host> 
< / service> 
< / services>解决方案3：使用mexTcpBinding 
 $ b $ 。   b 
 
 < services> 
< service name =FirstWcfService.Service
 behaviorConfiguration =ServiceBehavior> 
< endpoint 
 address =FirstWcfService
 binding =netTcpBinding
 contract =FirstWcfService.IService/> 
< endpoint 
 address =mex
 binding =mexTcpBinding
 contract =IMetadataExchange/> 
 ...... 
< / service> 
< / services> 
  
这三个选项中的任何一个都应该可以解决。
 
 
 
谨慎的一句话：我发现调用你的服务行为配置ServiceBehavior是很危险的...... 
 < serviceBehaviors> 
< behavior name =ServiceBehavior> 
  
我的建议：调用你的第一个和默认配置只是普通的默认（或DefaultBehavior / p> 
 
 
 < serviceBehaviors> 
< behavior name =Default> 
  
，如果您有多个配置，只有开始给出其他名称。 
 
 
 
调用这个 ServiceBehavior 似乎在一段时间后要求麻烦..... 
 
I am trying to create a simple ConsoleApplication in which i would like to host a simple wcf service.



Here is the code for my 
namespace HostConsoleApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            using (System.ServiceModel.ServiceHost host = new System.ServiceModel.ServiceHost(typeof(FirstWcfService.Service)))
            {
                host.Open();
                Console.WriteLine("Sai");
                Console.ReadLine();
            }
        }
    }
}

Then i have added an app.config which looks like this:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <services>
            <service name="FirstWcfService.Service" behaviorConfiguration="ServiceBehavior">
                <endpoint address="FirstWcfService" binding="netTcpBinding" contract="FirstWcfService.IService"/>
                <endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />
                <host>
                    <baseAddresses>
                        <add baseAddress="net.tcp://localhost:9101/"/>
                    </baseAddresses>
                </host>
            </service>
        </services>
        <behaviors>
            <serviceBehaviors>
                <behavior name="ServiceBehavior" >
                    <serviceMetadata httpGetEnabled="false" />
                </behavior>
            </serviceBehaviors>
        </behaviors>
    </system.serviceModel>
</configuration>

When i run the host console app i get this exception:

  
System.InvalidOperationException was
  unhandled   Message="Could not find a
  base address that matches scheme http
  for the endpoint with binding
  MetadataExchangeHttpBinding.
  Registered base address schemes are

 解决方案 
Well, I think the problem is this:



    

  • you have a base address for net.tcp
    • 

  • you have a MEX http endpoint defined (but no http base address)
    • 




Basically if you want to use MEX over http, you need to supply either a full address for the MEX endpoint, or a http base address (if you only specify a relative address).



Solution 1: specify a full address for the MEX endpoint:
 <services>
    <service name="FirstWcfService.Service" 
              behaviorConfiguration="ServiceBehavior">
       <endpoint 
           address="FirstWcfService" 
           binding="netTcpBinding" 
           contract="FirstWcfService.IService"/>
       <endpoint 
           address="http://localhost:9102/FirstWcfService/mex"
           binding="mexHttpBinding" 
           contract="IMetadataExchange"  />
        ......
    </service>
</services>

Solution 2: define an HTTP base address, too:
 <services>
    <service name="FirstWcfService.Service" 
              behaviorConfiguration="ServiceBehavior">
       <endpoint 
           address="FirstWcfService" 
           binding="netTcpBinding" 
           contract="FirstWcfService.IService"/>
       <endpoint 
           address="mex"
           binding="mexHttpBinding" 
           contract="IMetadataExchange"  />
       <host>
           <baseAddresses>
               <add baseAddress="net.tcp://localhost:9101/"/>
               <add baseAddress="http://localhost:9102/"/>
           </baseAddresses>
       </host>
    </service>
</services>

Solution 3: use the mexTcpBinding instead 
 <services>
    <service name="FirstWcfService.Service" 
              behaviorConfiguration="ServiceBehavior">
       <endpoint 
           address="FirstWcfService" 
           binding="netTcpBinding" 
           contract="FirstWcfService.IService"/>
       <endpoint 
           address="mex"
           binding="mexTcpBinding" 
           contract="IMetadataExchange"  />
        ......
    </service>
</services>

Any of those three options should should solve it.



A word of caution: I find it quite risky to call your service behavior configuration "ServiceBehavior"...... 
<serviceBehaviors>
    <behavior name="ServiceBehavior" >

My recommendation: call your first and default configuation just plain "Default" (or "DefaultBehavior")
<serviceBehaviors>
    <behavior name="Default" >

and only start giving out other names if you have multiple configurations. 



Calling this ServiceBehavior just seems to be asking for trouble some time later on.....
