python - Flask get_json does not return correct JSON -


i having problem decoding json flask.

from ajax send following request:

$.ajax ({ type: "post", url: 'http://localhost:5000/getsurveyresult/', datatype: 'json', contenttype: 'application/json', async: true, data: '{"1":"utf-16","2":"ja"}', success: function () { alert("thanks!"); }

server side:

@app.route('/getsurveyresult/', methods=['post']) def get_survey_result():     request_json = request.get_json()     print request_json     return "ok"

the print gives me weird output , cannot access fields using request_json[1]:

{u'1': u'utf-16', u'2': u'ja'}

the u in front of strings in printout signifies string unicode, it's standard python behaviour, see here : what 'u' symbol mean in front of string values?

as request_json variable, keys both strings , accessed request_json["1"] (note quotes around 1).

json allows keys strings design: https://www.w3schools.com/js/js_json_objects.asp

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
