我有一个Silverlight应用程序,该应用程序运行良好,可以访问Silverlight应用程序本身中托管的WCF服务。它使用的端口是1794。
I have a silverlight application which works perfectly and can access the WCF services which are hosted in silverlight application itself. The port it is using is 1794.
当我部署到其他服务器(开发,测试或登台)时,应用程序无法访问WCF服务。
When I deploy to other servers (dev or test or staging), the application is not able to access WCF services.
这是我的ServiceReference.ClientConfig的一个片段,
This is a snippet from my ServiceReference.ClientConfig looks like
<endpoint address="localhost:1794/MyWebService.svc" binding="customBinding" bindingConfiguration="CustomBinding_MyWebService" contract="ConfigMgmtServiceReference.MyWebService" name="CustomBinding_MyWebService" />我的根文件夹也包含clientaccesspolicy.xml文件。
My root folder contains the clientaccesspolicy.xml file too.
如何解决这个问题?
推荐答案我怀疑 localhost:1794 会引起问题-当Silverlight应用程序在客户端计算机上执行时,本地主机不会将其返回给服务器。
I suspect the localhost:1794 would be causing the issue - when the silverlight application executes on a client machine the localhost will not get it back to the server.
该技术我用来消除此类问题的方法是,以编程方式在运行时设置终点。我需要的两条信息是服务的Web项目在我的Web项目中的位置(这是提前知道的),以及从中提供了Silverlight应用程序的地址(域)(我可以找到)。
The technique i use to eliminate issues like this is to programmatically set the end points at run time. The two pieces of info i need are the location within my web project of the service (which is known ahead of time), and the address (domain) that the silverlight app has been served from (which i can find out).
private void initEndpoint(ServiceEndpoint endPoint, string serviceName) { Uri hostUri = Application.Current.Host.Source; string wcfBaseUri = string.Format("{0}://{1}:{2}/WebServices/", hostUri.Scheme, hostUri.Host, hostUri.Port); endPoint.Address = new EndpointAddress(new Uri(wcfBaseUri + serviceName)); }在这段代码中,文件夹 / WebServices 是我的Web服务位于我的Web应用程序中的位置。然后,我这样调用该函数:
In this piece of code, the folder /WebServices is where my web services are located within my web app. I then call the function like this:
LoggingServiceClient loggingService = new LoggingServiceClient(); initEndpoint(loggingService.Endpoint, "LoggingService.svc");我的实际设置比这稍微复杂一些,因为我也希望能够覆盖它,并且手动配置终点,但是您已经明白了。通过这样做,我已经能够部署到各种设置,并且Web服务器在奇数端口上运行,并且silverlight-> webservice位每次都可以使用。
my actual setup is slightly more complex than that, because i also want to be able to override that and manually configure the end points, but you get the point. By doing this, i have been able to deploy to all sorts of setups, with webservers running on odd ports, and the silverlight->webservice bit just works every time.
