我有这个界面:
[ServiceContract]
public interface ILocationService
{
[OperationContract]
bool RegisterForNotification(string name, string uri);
[OperationContract]
bool UnRegisterForNotification(string name);
}
和这项服务:
[ServiceBehavior(InstanceContextMode=InstanceContextMode.Single)]
public class LocationBasedService : ILocationService
{
#region Registrations
public bool RegisterForNotification(string name, string uri)
{
return true;
}
public bool UnRegisterForNotification(string name)
{
return true;
}
#endregion
}
以及以下配置:
<configuration>
<system.serviceModel>
<services>
<service name="PushNotifications.Server.Service.LocationBasedService" >
<endpoint address="http://localhost:8000/LocationBasedService"
binding="basicHttpBinding"
contract="Services.Interface.ILocationService"/>
</service>
</services>
</system.serviceModel>
使用ServiceHost在WPF应用程序中托管自托管。代码如下:
private void startSrv_Click(object sender, RoutedEventArgs e)
{
try
{
host = new ServiceHost(typeof(LocationBasedService));
host.Open();
AddDiagnosticMessage("service successfully initialized");
AddDiagnosticMessage(string.Format("{0} is up and running with these end points", host.Description.ServiceType));
foreach (var se in host.Description.Endpoints)
AddDiagnosticMessage(se.Address.ToString());
}
catch (TimeoutException ex)
{
AddDiagnosticMessage(string.Format("The service operation timeod out. {0}", ex));
}
catch (CommunicationException ex)
{
AddDiagnosticMessage(string.Format("Could not start host service. {0}", ex));
}
catch (Exception ex)
{
AddDiagnosticMessage(ex.Message);
}
}
服务无异常启动。但是,当我将URL http://localhost:8000/LocationBasedService提交到浏览器时,我收到HTTP 400 Bad Request。如果我尝试使用Visual Studio的添加服务引用创建WCF客户端,则会出现以下错误:
的 'http://本地主机:8000 / LocationBasedService'。 内容类型application / soap + xml;服务http://localhost:8000/LocationBasedService不支持charset = utf-8。客户端和服务绑定可能不匹配。 远程服务器返回错误:(415)无法处理消息,因为内容类型为'application / soap + xml; charset = utf-8'不是预期的类型'text / xml;字符集= UTF-8' .. 如果在当前解决方案中定义了服务,请尝试构建解决方案并再次添加服务引用。
如果我尝试使用以下代码调用客户端,则会出现超时异常。
private void Button_Click(object sender, RoutedEventArgs e)
{
statusMessages.Add(GetFormattedMessage("initiailing client proxy"));
var ep = new EndpointAddress("http://localhost:8000/LocationBasedService");
var proxy = ChannelFactory<ILocationService>.CreateChannel(new BasicHttpBinding(), ep);
var register = proxy.RegisterForNotification("name1", @"http://google.com");
if (register)
{ Console.Writeline(register.ToString()); }
}
有人可以对我错过的内容给出一些见解。这应该是一个简单的练习:
TIA。
答案 0 :(得分:2)
通过添加以下代码解决了错误的HTTP请求:
host = new ServiceHost(typeof(LocationBasedService), new Uri("http://localhost:8000/LocationBasedService"));
// Enable metadata publishing.
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
host.Description.Behaviors.Add(smb);
host.Open();
至于服务超时,这是由我的个人防火墙引起的。我不得不将Visual Studio添加到允许的应用程序列表中。
重新开始营业。
