botframework - how to get back the "payload" of the button " Get Started " in c# -


i work microsoft bot framework in messenger , know how "payload" of button " started ", function should create in c# ?

you don't have - payload returned regular message, can use this:

if (activity.channelid == "facebook" && activity.text == "get_started_payload") {    // etc

note documentation lists restrictions on feature:

  • the welcome screen shown first time user interacts page on messenger.
  • only admins, developers, , testers of app can see when app in development mode.
  • your app must subscribed postback webook events.

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
