尝试通过c# RESTful服务接收COSM触发器HTTP Post，未收到警报。我采用了COSM API JSON有效负载，并在测试客户端中使用了它——这是有效的。当我设置提要并尝试调试触发器测试，或者只是强制触发器正常触发时，我的REST服务不会被调用。如果我尝试任何形式的测试客户端，服务都可以很好地处理JSON POST。
c#服务在这里:
[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = "cosm",
RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
string CosmAlert(CosmTrigger data);
其中CosmTrigger是我的类，镜像了cosmm Trigger字段。
我的COSM提要在这里。
我从COSM门户开始触发一个触发器，基于Twitter的触发器工作得很好，HTTP Post到我的URL不是。如何调试这个?
Cosm触发器目前不以JSON主体的形式发送触发器，它实际上发送一个URL编码的请求，其中JSON触发器主体编码为一个名为'body'的参数。
在测试触发器上使用http://requestb.in，并查看原始输出，基本请求如下所示:
POST /103s0dh1 HTTP/1.1
X-Request-Id: e05e9d699edbd5f584fc491cf9416df747be4df4

不幸的是，我不是c#专家，但我怀疑问题是与服务没有配置为从标准的urlencoded请求体中提取JSON体有关，但也许这可能会为了解c#的人提供线索，以找出问题所在。
测试和工作代码-
[OperationContract]
[WebInvoke(Method = "POST",
BodyStyle = WebMessageBodyStyle.WrappedRequest,
UriTemplate = "cosm")]
string cosmStream(Stream body);
