|
38
|
|
|
The <info>channels:history</info> command returns a portion of messages/events from the specified channel. |
|
39
|
|
|
To read the entire history for a channel, run the command with no `latest` or `oldest` options, and then continue paging |
|
40
|
|
|
using the instructions below. |
|
41
|
|
|
|
|
42
|
|
|
The messages array up to 100 messages between `--latest` and `--oldest`. If there were more than 100 messages between |
|
43
|
|
|
those two points, then has_more will be true. |
|
44
|
|
|
|
|
45
|
|
|
If a message has the same timestamp as latest or oldest it will not be included in the list. This allows a client to fetch |
|
46
|
|
|
all messages in a hole in channel history, by running the <info>channels.history</info> command with `--latest` |
|
47
|
|
|
set to the oldest message they have after the hole, and `--oldest` to the latest message they have before the hole. |
|
48
|
|
|
If the response includes `has_more` then the client can make another call, using the `ts` value of the final messages as |
|
49
|
|
|
the latest param to get the next page of messages. |
|
50
|
|
|
|
|
51
|
|
|
If there are more than 100 messages between the two timestamps then the messages returned are the ones closest to latest. |
|
52
|
|
|
In most cases an application will want the most recent messages and will page backward from there. If oldest is provided |
|
53
|
|
|
but not latest then the messages returned are those closest to oldest, allowing you to page forward through history if desired. |
|
54
|
|
|
|
|
55
|
|
|
If either of the latest or oldest arguments are provided then those timestamps will also be included in the output. |
