Question

使用WCF，可以为webHTTPBinding生成帮助。通过WebGet操作，它就像魅力一样。但是，使用WebInvoke（Method =“POST”）并没有给我任何帮助。在页面中，我可以看到：

URL：   http://localhost/edumatic3/trunk/services/service.svc/rest/saveUser

HTTP方法：POST

消息方向格式正文

请求未知无法生成架构文档。

响应未知无法生成架构文档。

有什么想法吗？

Web.Config system.serviceModel

服务合同： GetNodeByKey给了我明确的帮助。 SaveUser没有。

[ServiceContract]
public interface IService
{
    [OperationContract]
    [WebGet(UriTemplate = "login?userName={userName}&password={password}")]
    void Login(string userName, string password);


    [OperationContract]
    [WebGet(UriTemplate = "getNodeByKey/{key}?getAllDescendants={getAllDescendants}"
        , ResponseFormat = WebMessageFormat.Json)]
    [ServiceKnownType(typeof(BranchNodeDTO))]
    [ServiceKnownType(typeof(LeafNodeDTO))]
    [ServiceKnownType(typeof(CasusNodeDTO))]
    [ServiceKnownType(typeof(BucketNodeDTO))]
    NodeDTO GetNodeByKey(string key, string getAllDescendants);

    [OperationContract]
    [WebInvoke(UriTemplate = "saveUser", Method = "POST"
        , BodyStyle = WebMessageBodyStyle.WrappedRequest)]
    UserDto SaveUser(UserDto user, int channelId);
}

您的DataContract怎么样？有没有FlagsAttribute的枚举？看来当你使用 [Flags] 时，WCF无法正确生成帮助页面。
