那些遇到过的问题

在从 net.tcp 协议连接到 WCF 的端点上侦听的问题

Nɪs*_*ʜ ॐ 4 asp.net iis wcf endpoint net.tcp

这个奇怪的错误是在发布这篇文章的前一天出现的。以前它工作正常，但现在不行了。

在重新启动系统的一个动作中，错误消失并能够访问应用程序。

再次重新启动系统后，错误开始出现而不知道根本原因。

启用的协议： net.tcp,http

我可以浏览以下链接

这是导致异常的以下代码段

objCheckUserLoginResponse = AuthenticationManagerClient.Check(objCheckUserLoginRequest, objCustomer);

例外：

The message could not be dispatched because the service at the endpoint address 'net.tcp://localhost/TAServices/AuthenticationManager.svc' is unavailable for the protocol of the address. 
System.ServiceModel.EndpointNotFoundException: The message could not be dispatched because the service at the endpoint address 'net.tcp://localhost/TAServices/AuthenticationManager.svc' is unavailable for the protocol of the address.

我通过在启动英特尔® 显卡驱动程序更新后释放OneApp.IGCC.WinService.exe占用端口来解决此问题808。但这听起来很奇怪，因此请检查是否SMSvcHost.exe已列出808端口。

C:\Windows\system32>netstat -ano | find "808"
  TCP    0.0.0.0:808            0.0.0.0:0              LISTENING       4356

如果您发现该进程名称未SMSvcHost.exe列出，例如OneApp.IGCC.WinService.ex或具有其他名称，则继续执行这些步骤，否则停止此处。

因此，在我的情况下，按名称的进程OneApp.IGCC.WinService.ex已占用808具有唯一进程 ID 的端口作为从提升的提示符5068 执行命令TASKKILL /F /PID <ProcessId>。

C:\Windows\system32>netstat -ano | find "808"

  TCP    [::]:808               [::]:0                 LISTENING       5068

C:\Windows\system32>taskkill /F /PID 5068
SUCCESS: The process with PID 5068 has been terminated.

然后重新启动Net.Tcp Port Sharing Service从services.msc

即使在重新启动后，系统OneApp.IGCC.WinService.exe也会SMSvcHost.exe通过监听808端口来覆盖。所以禁用运行Intel(R) Graphics Command Center Service (C:\Windows\System32\DriverStore\FileRepository\igcc_dch.inf_amd64_26b207b939eae50e)fromservices.msc

看来您在 IIS 中托管 WCF 服务项目并尝试使其正常HTTP工作Nettcp。为了使其通过 NetTcp 协议工作，我们应该在 IIS 站点绑定模块中启用某些 Window 功能和 NetTcp 绑定。另外，我们应该使用 Nettcpbinding 配置服务端点，但您的Webconfig文件中没有设置该端点。System.servicemodel请考虑用以下配置替换该部分。

为了在 IIS 中支持 Net.tcp 协议，请启用以下 Windows 功能。 https://i.stack.imgur.com/15e3G.png
随后，在网站上添加Net.tcp支持。
https://i.stack.imgur.com/LM9jv.png
最后，添加与 net.tcp 协议的站点绑定。注意，808是net.tcp协议的默认端口。请勿使用其他网站已使用的端口号。
https://i.stack.imgur.com/0yVz4.png
请参考以下链接。
找不到与绑定 NetTcpBinding 的端点的方案 net.tcp 相匹配的基地址。基地址方案是 [http]
如果问题仍然存在，请随时告诉我。
