Question

尝试通过C＃RESTful服务接收COSM触发器HTTP Post，但不接收警报。我使用了COSM API JSON有效负载并从测试客户端使用它 - 这很有用。当我设置我的源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，该服务处理JSON POST就好了。

C＃服务在这里：

    [OperationContract]
    [WebInvoke(Method = "POST", UriTemplate = "cosm", 
        RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
    string CosmAlert(CosmTrigger data);

CosmTrigger是我的班级镜像COSM Trigger fields。

我的COSM Feed是here。

我从COSM门户开始触发触发器，基于Twitter的触发器工作正常，HTTP Post到我的URL不是。如何调试？

Answer 1

Cosm触发器当前不会将触发器作为JSON主体发送，它实际上发送了一个URL编码请求，其中JSON触发器主体被编码为一个名为＆＃39; body＆＃39;。

的参数。

在测试触发器上使用http://requestb.in，并查看原始输出，这显示基本请求如下所示：

POST /103s0dh1 HTTP/1.1
X-Request-Id: e05e9d699edbd5f584fc491cf9416df747be4df4

不幸的是，我不是C＃专家，但我怀疑这个问题与未配置为从标准urlencoded请求体中提取JSON主体的服务有关，但也许这可能会提供如何解决的问题弄清楚知道C＃的人会出现什么问题。

Answer 2

经过测试和运作的代码 -

[OperationContract]  
[WebInvoke(Method = "POST",  
BodyStyle = WebMessageBodyStyle.WrappedRequest,  
UriTemplate = "cosm")]  
string cosmStream(Stream body);

COSM触发器使用HTTP Post中的C＃提取JSON值
