MS BOT框架（自适应卡）：如何从directline发送值（Stepcontext.Value）？

Question

我在Azure中部署了一个Bot，Bot显示欢迎消息OnMemberAdd。它的自适应卡，所以输入的值都发送到stepcontext.value。我已经将其与多个渠道集成，对于directline，我想绕过欢迎卡，直接将消息传递到stepcontext.value，因此显示第二个提示而不是第一个。我试过下面的方法，但没有用，请大家帮忙。

      (async function() {
        // In this demo, we are using Direct Line token from MockBot.
        // Your client code must provide either a secret or a token to talk to your bot.
        // Tokens are more secure. To learn about the differences between secrets and tokens
        // and to understand the risks associated with using secrets, visit https://docs.microsoft.com/en-us/azure/bot-service/rest-api/bot-framework-rest-direct-line-3-0-authentication?view=azure-bot-service-4.0

        const { token } = { token};

        // We are using a customized store to add hooks to connect event
        const store = window.WebChat.createStore({}, ({ dispatch }) => next => action => {
 if (action.type === 'DIRECT_LINE/CONNECT_FULFILLED') {
   dispatch({
     type: 'WEB_CHAT/SEND_EVENT',
     payload: { 
                name: 'userInfo',
       value: { fname:'user', lname:'test', pnumber:'0678775453'} 
                }
   });
 }

 return next(action);
        });

        const styleOptions = {
 botAvatarImage:
   '',
 botAvatarInitials: 'Chatbot',
 userAvatarImage: '',
 userAvatarInitials: 'User',
 showNub: true,
 bubbleFromUserNubOffset: 'bottom',
 bubbleFromUserNubSize: 10,
 bubbleFromUserBorderColor: '#0077CC',
 bubbleNubOffset: 'top',
 bubbleNubSize: 0,
 bubbleBorderColor: '#009900',
 sendBoxButtonColor: '#009900',
 hideUploadButton: true,
 hideSendBox : true
        };
        window.WebChat.renderWebChat(
 {
   directLine: window.WebChat.createDirectLine({ token }),
   store,
            styleOptions
 },
 document.getElementById('webchat')
        );

        document.querySelector('#webchat > *').focus();
      })().catch(err => console.error(err));
    </script>
  </body>
</html>

我试过通过postman发送数据，效果很好，但是当我用上面的代码发送时，却不能正常工作。

{
    "type": "message",
    "from": {
        "id": "user1"
    },
    "value": 
    {
        "fname":"user",
        "lname":"test",
        "pnumber":"0678787543"
    }
}
