Send message to bot on click of menu item bot framework

问题

I am having a challenge to send message to bot on click of static menu item in Microsoft boframework webchat. I have modified the top nav and have static menu items and on click of any menu item that text should be sent to bot as message.

I read over the Microsoft documentation and I see that we need to post to direct line so send message to bot. please refer https://docs.microsoft.com/en-us/azure/bot-service/rest-api/bot-framework-rest-direct-line-3-0-send-activity?view=azure-bot-service-4.0

I am wondering if there is any alternative apart from this as I am not able to make the api properly and invoke on click of item.

MenuItemClick(event) {
console.log(event.target.innerText);
Needle('post','https://directline.botframework.com/v3/directline/conversations', headers, {});
}

I am expecting on click of the menu item the text associated with menu item should go to the bot as message.

I'm assuming you are building on top of the Minimizable Web Chat sample. Instead of making a post request to Direct Line to send a message, I would recommend dispatching a sendMessage action from Web Chat's store. Most of the logic is already there for you. You just need to import the sendAction method from Web Chat Core and define a handleMenuItemClick function. Take a look at the code snippets bellow.

Minimizable Web Chat Sample

...
// Import `sendMessage` actiion from Web Chat Core
import sendMessage from 'botframework-webchat-core/lib/actions/sendMessage';

...

export default class extends React.Component {
  constructor(props) {
    super(props);
    ...
    // bind `handleMenuItemClick` to component
    this.handleMenuItemClick = this.handleMenuItemClick.bind(this);
    ...
  }

  // add `handleMenuItemClick` to component
  handleMenuItemClick({ target: { innerText }}) {
    const { store: { dispatch }} = this.state;
    dispatch(sendMessage(innerText));
  }

  render() {
    const { state: {
      minimized,
      newMessage,
      side,
      store,
      styleSet,
      token
    } } = this;

    return (
      <div className="minimizable-web-chat">
         ...
      </div>
  }
}

Hope this helps!
