I am doing R&D on how to implement a pubnub access manager in swift, and after some research, I come to know :
- Swift SDK does not include pubnub.grant
- I need to achieve this using a pubnub function for serverless computing
I have created one function in the pubnub dashboard and created a module PubNub, also created a function with event type "On Request" and added code of grant.
export default (request, response) => {
const pubnub = require('pubnub');
const kvstore = require('kvstore');
let headersObject = request.headers;
let paramsObject = request.params;
let methodString = request.method;
let bodyString = request.body;
response.headers['Access-Control-Allow-Origin'] = '*';
response.headers['Access-Control-Allow-Headers'] = 'Origin, X-Requested-With, Content-Type, Accept';
response.headers['Access-Control-Allow-Methods'] = 'GET, POST, OPTIONS, PUT, DELETE';
response.headers['Content-Type'] = 'application/json';
var uuid = 'aartisagarvadgama'
return pubnub.grant({
channels: ['channel_atts_pubnub'],
read: true, // false to disallow
write: false, // false to disallow,
authKeys: [uuid],
ttl: 0
}).then(() => {
console.log('grant success')
response.status = 200;
return response.send(uuid);
}).catch((error) => {
console.log(error);
response.status = 400;
return response.send();
});
};
I am calling this above function by copying URL from function and getting success code, But how this can reflect my iOS application.
Please let me know anyway by which I can achieve the access manager in my app.
As per my understanding, I need to create a function and by calling that function I can grant the user. After that When I will try to subscribe or publish, I will get 200 instead of 403. Any help will be appreciated. Please help me.
