访问WCF Rest服务（WebGet）时出现错误请求400

Question

我在visual studio 2008上构建了一个WCF REST Web服务（在windows xp上）

当我尝试通过URL访问webservice时，它返回400错误的请求错误。

[WebGet(ResponseFormat = WebMessageFormat.Xml, UriTemplate = "hello/{Name}")]
[OperationContract]
string SayHello(string Name);

请帮忙。

的web.config

<system.serviceModel>
    <services>
      <service behaviorConfiguration="DNNServiceBehavior" name="DNNService">
        <endpoint address="" binding="wsHttpBinding" contract="IDNNService">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding"  contract="IMetadataExchange" />
        <endpoint address="rest" binding="webHttpBinding" behaviorConfiguration="httpBehavior" contract="IDNNService"/>
