C# 如何用C语言提取通道数据#

我正在通过通道数据将数据从web聊天客户端发送到Bot，方法如下：

const store = window.WebChat.createStore({}, ({ dispatch }) => next => action => {
  if (action.type === 'DIRECT_LINE/POST_ACTIVITY') {
   // The channelData submitted here is very similar to HTTP cookies and vulnerable to forgery attack.
   // Make sure you use signature to protect it and verify the signature on the bot side.
   // To minimize unexpected behaviors, we recommend to treat the "action" object as if it is immutable.
   // We use simple-update-in package to update "action" with partial deep cloning.
   action = window.simpleUpdateIn(
     action,
     ['payload', 'activity', 'channelData', 'myCustomProperty'],
     () => 'Custom value'
   );
 }

 return next(action);
});

如何使用C#？

在服务器端访问此数据您可以在下面的上下文对象完整路径下的channelData下访问它

dialogContext.Context.Activity.ChannelData
