如何从根目录访问WCF服务的客户端访问策略操作? [英] How can I get my WCF service's client access policy operation to be accessible from the root?

问题描述

我可以通过以下操作在WCF服务中托管客户端访问策略:

I have the following operation for hosting my client access policy in my WCF service:

[OperationContract]
[WebGet(UriTemplate = "/clientaccesspolicy.xml")]
XElement RetrieveClientAccessPolicy();

public XElement RetrieveClientAccessPolicy()
{
    String policy = @"<?xml version=""1.0"" encoding=""utf-8""?>
                    <access-policy>
                        ...
                    </access-policy>";

    return XElement.Parse(policy);
}

当我尝试从Silverlight应用程序连接到我的服务时，出现错误，因为它找不到客户端访问策略.在这里寻找它:

When I try to connect to my the service from my silverlight app, I get an error because it can't find the client access policy. It's looking for it here:

http://MyServer/clientaccesspolicy.xml

在IE中浏览时，我得到一个404.但是，如果我浏览到这里，则可以找到clientaccesspolicy.xml文件:

When I browse there in IE, I get a 404. However, I can find the clientaccesspolicy.xml file if I browse to here:

http://MyServer/server/clientaccesspolicy.xml

如何使我的操作能够从根目录而不是从该目录(服务器是服务的名称)访问客户端访问策略文件?

How can I get my operation to make the client access policy file accessible from the root, and not from that directory (server is the service's name)?

推荐答案

我猜测您没有使用IIS来承载服务，因为您试图通过WCF调用返回clientaccesspolicy.xml.

I am guessing that you are not using IIS to host the service since you are trying to return the clientaccesspolicy.xml via a WCF call.

对于自托管WCF服务，我认为您将必须为App.config中的RetrieveClientAccessPolicy()调用设置单独的服务端点和协定.该服务的基本地址为http://localhost，而您的主服务的基本地址为http://localhost/server.

In the case of a self-hosted WCF service, I think you are going to have to set up a separate service endpoint and contract for your RetrieveClientAccessPolicy() call in your App.config. That service would have a baseAddress of http://localhost where your main service would have a base address of http://localhost/server.
