Utility Methods API for Vue SDK

The methods on this page are utility methods that don't fit into other categories.

decrypt(data: string, customCipherKey: ?string)

* required

Parameter	Description
data * Type: String	The data to decrypt.
customCipherKey Type: String	If it's not provided, the cipher key from config will be used.

Time

This function will return a 17 digit precision Unix epoch.

The timetoken is constructed using the following algorithm:

timetoken = (Unix epoch time in seconds) * 10000000

Example of creating a timetoken for a specific time and date

08/19/2013 @ 9:20pm in UTC = 1376961606
timetoken = 1376961606 * 10000000

import PubNubVue from 'pubnub-vue';

const pubnub = PubNubVue.getInstance();

pubnub.time(function(status, response) {
    if (status.error) {
        // handle error if something went wrong based on the status object
    } else {
        console.log(response.timetoken);
    }
});

Response

//Example of status
{
    error: false,
    operation: 'PNTimeOperation',
    statusCode: 200

    console.log(timetoken);
}).catch((error) => {
    console.log(error);
});

Example above show how to create notification payload which APNS will try to redeliver few times (if devices not active) and give up after 10 seconds since moment when it has been scheduled.

Additionally this invitation notification will be grouped along with other invitation notifications (using provided collapse_id as group identifier) and shown as one in notification center.

Returns

Configured and ready to use NotificationsPayload instance.
