Question

我的客户遇到此错误。 System.ServiceModel.CommunicationException：'收到对http://localhost:8099/IService的HTTP响应时发生错误。这可能是由于服务端点绑定未使用HTTP协议。这也可能是由于服务器终止了HTTP请求上下文（可能是由于服务关闭了）。请参阅服务器日志以获取更多详细信息。客户端配置

我拒绝的代码

ServiceReferenceMrChicken.ProgrammServiceClient client = new ServiceReferenceMrChicken.ProgrammServiceClient();
            var users = client.GetUsers();
            dataGrid.ItemsSource = users;

我拒绝的代码

ServiceReferenceMrChicken.ProgrammServiceClient client = new ServiceReferenceMrChicken.ProgrammServiceClient();
            var users = client.GetUsers();

在托管服务的过程中，对我来说似乎有些不对劲。您可以通过访问服务的WSDL来验证它是否被正确托管。

http://x.x.x.x:8009/service1.svc?wsdl

通常，服务端点地址由IIS站点绑定而不是服务配置文件的基地址提供，因为WCF服务也由IIS托管为网站。因此，以下代码段是不必要的。

   <host>
      <baseAddresses>
        <add baseAddress="http://localhost:8099/" />
      </baseAddresses>
    </host>

同时，我们应该在IIS网站绑定模块中提供一个http基地址。
然后服务地址将为http://x.x.x.x:9001/service1.svc，我们可以使用“添加服务引用向导”键入服务基址以在客户端使用它。

随时让我知道是否有什么可以帮助您的。
