TELEGRAM with FIVEWIN (Tutorial)

[dagiayunus]

Dear Sir,

Thanks to Mr. Antonio to encourage to write the application.

1. install TELEGRAM (message application like whatsapp) and setup
2. talk with botfather and create bot and write down the TOKEN
https://telegram.me/BotFather
http://botsfortelegram.com/project/the-bot-father/

Now send few text msg to your BOT using your mobile.

Below is the example to retrive messages

Code: Select all  Expand view

function Main()  

   local odoc  := CreateObject( "MSXML2.DOMDocument" )
   local ohttp := CreateObject( "MSXML2.XMLHTTP" )
   local cTOKEN:= "Paste your TOKEN here"
   local URL:="https://api.telegram.org/bot"+cTOKEN+"/getUpdates"

   ohttp:Open( "POST" ,URL, .F. )
   oHttp:SetRequestHeader("Accept" ,"application/xml")
   oHttp:SetRequestHeader("Content-Type","application/json")
   oDoc:async:=.f.
   oDoc:LoadXml('<?xml version=""1.0"" encoding=""utf-8""?>')
   oHttp:Send(oDoc:xml)
   
   cText:=Alltrim(oHttp:responseText)
   cText=strtran(cText,'{"ok":true,"result":[','')
   cText=alltrim(cTExt)

   ar:=HB_ATOKENS( cTEXT, '{"update_id":' )  // split json string to array

 
 
 for i=2 to len(ar)
      x:=ar[i]
      nUpdateId:=GetUpdateId(x)
      ?nUpdateId, "Message_id",ExtractValue(x,"message_id"),"From_Id",ExtractValue(x,'from":{"id'),"Chat_Id",ExtractValue(x,'"chat":{"id')
      fName:=ExtractValue(x,"first_name")
      fname:=strTran(fname,'}','')
      ?fname
      ?GetMsg(x)
   
 next i

return nil

function ExtractValue(x,srchValue)

return SubStr( x, nAt := At( srchValue, x ) + Len( srchValue )+2, At( ",", SubStr( x, nAt  ))-1)
//?SubStr( x, nAt := At( "message_id", x ) + Len( "message_id" )+2, At( ",", SubStr( x, nAt + Len( "message_id" ) )) -1 )


function GetUpdateId(x)
substr(x,1,at(",",x)-1)

function Getmsg(x)
cMsg:=RIGHT(x,LEN(x) - RAT(":", x) - 1)
cMsG:=substr(cMsg,1,rat('"',cMsg)-1)
return cMsg
