WCF SOAP服务方法无故超时 [英] WCF SOAP Service method timeout for no reason
问题描述
我有一个带有 wsHttpBinding 的 WCF SOAP 服务,我有 2 个方法,第一个执行正常,但由于某种原因,对第二个方法的调用超时.我调试了该方法,我的代码一切正常,它执行并返回,但是在客户端中,在同一台机器上,请求超时.我新建了一个WCF Service Application项目,把整个code+config复制到新项目中,运行一下,方法几次都没有超时,然后突然又开始了.
I have a WCF SOAP Service with wsHttpBinding, i have 2 methods, the first one executes fine, but for some reason the call to the second method times out. I debuged the method and the everything is fine i my code, it executes and returns, but the in the client, on the same machine, the requests times out. I created a new WCF Service Application project, copied the entire code + config to the new project, ran it, and the method didn't time out for a few times, then suddenly it started doing it again.
这里是配置:
<system.serviceModel>
<services>
<service behaviorConfiguration="PolicyServiceBehavior" name="IST.Broker.Services.PolicyServiceV2.PolicyService">
<endpoint address="" binding="wsHttpBinding" bindingConfiguration="PolicyServiceBindingConfiguration"
contract="IST.Broker.Services.PolicyServiceV2.IPolicyService" />
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
<host>

<add baseAddress="http://localhost:63915/" />
</baseAddresses>
<timeouts closeTimeout="00:01:00" openTimeout="00:01:00" />

</service>

服务合同:
[ServiceContract(SessionMode = SessionMode.Required)]
public interface IPolicyService
{
[OperationContract(IsInitiating = true)]
void Initialize(int employeeId);
[OperationContract(IsInitiating = false, IsTerminating = false)]
GetPolicyResponse GetPolicy(GetPolicyRequest request);
[OperationContract(IsInitiating = false, IsTerminating = false)]
CreateMtplApplicationResponse CreateMtplApplication(CreateMtplApplicationRequest request);
[OperationContract(IsInitiating = false, IsTerminating = true)]
void SignOut();
}
和实现:
[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, InstanceContextMode = InstanceContextMode.PerSession)]
public class PolicyService : IPolicyService
{
private Employee _currentEmployee;
public GetPolicyResponse GetPolicy(GetPolicyRequest request)
{
return new GetPolicyResponse(PolicyManager.GetPolicy(request.Id, request.PolicyNumber));
}
public void Initialize(int employeeId)
{
if (!InsuranceCompaniesServiceManager.IsInitialized)
{
var appPhysicalPath = HostingEnvironment.ApplicationPhysicalPath;
_currentEmployee = EmployeeManager.GetEmployee(employeeId);
InsuranceCompaniesServiceManager.Initialize(_currentEmployee, appPhysicalPath);
}
}
public CreateMtplApplicationResponse CreateMtplApplication(CreateMtplApplicationRequest request)
{
return new CreateMtplApplicationResponse(PolicyManager.CreateMtplApplication(request.CompanyId, request.Policy.ToBusinessObject(), request.Vehicle.ToBusinessObject(),
request.Clients.Select(x => x.ToBusinessObject()).ToList(), request.GreenCard.ToBusinessObject(), request.Sticker.ToBusinessObject()));
}
public void SignOut()
{
}
}
该方法正在调用内部正在调用另一个服务的 DLL.
The method is calling a DLL that inside is calling another service.
推荐答案
在下面注释掉,因为它会在配置代理时自动添加.
Comment out below line because it'll be added automatically while configuring the proxy.
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
如果要查看,请右键单击您添加服务代理的服务代理,然后选择配置服务引用",您会注意到最后在服务的 URL 中添加了/mex
If you want to check, Right click on service proxy where you added service proxy, and select "Configure Service Reference" and you'll notice /mex is added in URL of the service at last
