Restful WCF 默认值

Question

lyDefinition of the resources

[OperationContract]
[WebGet(UriTemplate = "getbydaterange/{insId}/{startDate}/{endDate}", ResponseFormat = WebMessageFormat.Json)]
List<RestfulServiceObj> GetMyObjectsByDateRange(string insId, string startDate, string endDate);

如何使最后两个参数可选？即，我希望底部三个调用起作用，

"http://domain.com/service.svc/myid/"

"http://domain.com/service.svc/myid/07-07-2011"

"http://domain.com/service.svc/myid/01-01-2011/07-08-2011"

但只有最后一个调用起作用，其余调用给出丢失参数错误。

谢谢 看涨

我相信您这样做的方式与重载方法调用的方式相同：

[OperationContract]
[WebGet(UriTemplate = "getbydaterange/{insId}", ResponseFormat = WebMessageFormat.Json)]
List<RestfulServiceObj> GetMyObjectsByDateRange(string insId);

[OperationContract]
[WebGet(UriTemplate = "getbydaterange/{insId}/{startDate}", ResponseFormat = WebMessageFormat.Json)]
List<RestfulServiceObj> GetMyObjectsByDateRange(string insId, string startDate);

[OperationContract]
[WebGet(UriTemplate = "getbydaterange/{insId}/{startDate}/{endDate}", ResponseFormat = WebMessageFormat.Json)]
List<RestfulServiceObj> GetMyObjectsByDateRange(string insId, string startDate, string endDate);
