如何访问 silverlight 中的工作流服务？

发布于 2024-12-01 04:59:26 字数 638 浏览 2 评论 0原文

我有一个名为 GetDataWorkflowService.xamlx 的工作流服务，我想在 Silverlight 中使用它。

当我向应用程序添加服务引用时，它会显示一条消息“相对 URI 不支持此操作”。不过，它仍然添加了引用。

当我使用参考：时

Servicelient proxy=new ServiceClient();
proxy.GetDataCompleted += (o, a) => Debug.WriteLine("Result is " + a.Result);
proxy.GetDataAsync(123);

出现以下错误：

尝试向 URI“http://localhost:1234/GetDataWorkflowService.xamlx”发出请求时发生错误。这可能是由于尝试以跨域方式访问服务而没有适当的跨域策略，或者策略不适合 SOAP 服务。您可能需要联系服务的所有者来发布跨域策略文件并确保它允许发送与 SOAP 相关的 HTTP 标头。此错误也可能是由于在 Web 服务代理中使用内部类型而不使用 InternalsVisibleToAttribute 属性造成的。请参阅内部异常以了解更多详细信息。

我不明白发生了什么事。

原文

I have one worflow service named GetDataWorkflowService.xamlx that I want to use in Silverlight.

When I add a service reference to my application, it gives a message 'This Operation is not supported for the relative URI.' It still adds the reference, however.

When I use the referece:

Servicelient proxy=new ServiceClient();
proxy.GetDataCompleted += (o, a) => Debug.WriteLine("Result is " + a.Result);
proxy.GetDataAsync(123);

I get the following error:

An error occurred while trying to make a request to URI 'http://localhost:1234/GetDataWorkflowService.xamlx'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details.

I don't understand what's happening.
