如何编辑 PubNub 消息并添加对单个消息的反应

Question

I have been working with PubNub, I tried storage and playback to update ( edit ) message, but failed. Kindly make me understand with code example, how to do it.

Answer 1

Can you provide some examples of your code? You can find the docs for storage and playback at: https://www.pubnub.com/docs/web-javascript/api-reference-storage-and-playback

1st thing you need to do is create a PubNub Client:

var pubnub = new PubNub({
    subscribeKey: "mySubscribeKey",
    publishKey: "myPublishKey",
    cipherKey: "myCipherKey",
    authKey: "myAuthKey",
    logVerbosity: true,
    uuid: "myUniqueUUID",
    ssl: true,
});

Then you can make a history call to a specific channel you want messages for:

pubnub.history(
    {
        channel: 'channel ID you want history for',
        count: 100, // how many items to fetch
        stringifiedTimeToken: true, // false is the default
    },
    function (status, response) {
        // handle status, response
    }
);

After that you can just load the JSON into your UI

Docs on editing a message: https://www.pubnub.com/docs/web-javascript/message-update-delete

To edit a message

Using the Interleaving pattern, you publish new versions of the same message to the same channel just like normal publishes. The subsequent messages must use the same message_id as the original message...

Let me know if this helps! Mathew

thanks I found the solution: just using pubnub.addMessageAction() and pubnub.removeMessageAction() like this:

pubnub.addMessageAction(
{
    channel: 'channel1'
    messageTimetoken: '15610547826970040',
    action: {
        type: 'reaction',
        value: 'smiley_face',
    },
},
function(status, response) {

});
