wcf System.ServiceModel.AddressAlreadyInUseException [英] wcf System.ServiceModel.AddressAlreadyInUseException

问题描述

如果这个问题在 stackOverflow 上出现两次，我们深表歉意

Apologies if this question appears twice on stackOverflow

我正在尝试在 Windows Server 2003 机器上运行 wcf 服务.当服务主机调用 Open() 时，我收到 System.ServiceModel.AddressAlreadyInUseException 异常，它告诉我以下错误:

Im trying to run a wcf service on a windows server 2003 box. Im getting a System.ServiceModel.AddressAlreadyInUseException exception when the servicehost calls Open() and it tells gives me the following error:

HTTP 无法注册 URL http://+:8080/LogoResizer/mex/ 因为另一个应用程序正在使用 TCP 端口 8080

HTTP could not register URL http://+:8080/LogoResizer/mex/ because TCP port 8080 is being used by another application

我读到我需要使用 httpcfg.exe 来注册我的命名空间，并且我使用了 GUI 工具 here 这样做，但我仍然得到上述异常.运行netstat -a"不会显示在端口 8080 上侦听的任何其他内容，并且运行httpcfg.exe query urlacl"会返回以下已注册的命名空间.

Ive read that I need to use the httpcfg.exe to register my namespace and Ive used the GUI tool found here to do it but I still get the above exception. Running "netstat -a" doesnt show anything else listening on port 8080 and running "httpcfg.exe query urlacl" returns me the following registered namespaces.

C:\Program Files\Support Tools>httpcfg 查询 urlacl网址:http://+:80/Temporary_Listen_Addresses/

C:\Program Files\Support Tools>httpcfg query urlacl URL : http://+:80/Temporary_Listen_Addresses/

URL : http://+:8080/LogoResizer/

ACL : D:(A;;GX;;;WD)

URL : http://+:8080/LogoResizer/mex/

ACL : D:(A;;GX;;;WD)

我的应用程序的配置如下:

ACL : D:(A;;GX;;;WD)

The config for my app is as below:

                    <add baseAddress="net.tcp://localhost:9000/" />

            <endpoint  address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
        </service>
    </services>
</system.serviceModel>

有谁知道我做错了什么，或者我如何注册我的命名空间以便我的服务有一个 http 端点?

Does anyone have any idea what Im doing wrong or how I can register my namespace so I can have a http endpoint for my service?

推荐答案

解决了.

问题是我的两个端点都在同一个端口上运行.在 Windows XP 下开发时，这不是问题，但会为您提供我在 Vista 或 Windows Server 2003 下尝试运行该服务时所写的例外情况.我只需要将我的服务器配置更新为以下内容

Problem was having both my endpoints running off the same port. This isnt an issue when developing under windows XP, but will give you the exceptions I wrote about when trying to run the service under Vista or windows server 2003. I just needed to update my server config to the following

   <baseAddresses>
                                    <add baseAddress="http://localhost:9000/mex/"/>
                                    <add baseAddress="net.tcp://localhost:9001/" />
                            </baseAddresses>
