c# - How to read Json data from Instagram RealTime API updates -

-

i'm trying use instagram realtime api updates whenever posts image specific tag, i've followed steps, i'm having problems read json data sent callback url. according instagram's documentation :

when posts new photo , triggers update of 1 of subscriptions, make post request callback url defined in subscription. post body contains raw text json body update objects.

i'm using c# , mvc 5, here's code read "raw text json body", note i'm saving json string in text file.

[httppost] public httpstatuscoderesult receive() {     string json;      using (var reader = new streamreader(request.inputstream))     {         json = reader.readtoend();     }      file.writealltext(path.combine(server.mappath("~/"), "test.txt"), json);      return new httpstatuscoderesult(200); }

the problem is, when receive request, file create, empty. there's wrong code? problem instagram's api? i'd appreciate this.

found it! set inputstream position 0 , works!
