Integrate Server Sent event api (EventSource) or streaming HTTP api

[theiosdevguy]

I have a .NET based HTTP streaming api that I need to integrate on my larval based PHP server application. I have been using Guzzle for it but it is blocking my entire server because of the infinite while loop I had to place. I was exploring this library but I am encountering issues with it. The streaming api is built in a way that it requires a GET HTTP call which redirects to the streaming URL.

Example - GET http://192.168.1.25:4590 (with Auth headers)
Response - Redirects to http://192.168.1.25:4591 (Streaming API)

The problem I am facing is that when I do a GET to http://192.168.1.25:4590, I see no chunk of data in

$response->on('data', function ($chunk) {
        echo $chunk;
});

In fact, the logs suggest that

$response->on('end', function() { echo 'DONE'; });

is called right away.

Please suggest a mechanism to integrate such a streaming api. Or may be the right question here should be how to handle HTTP redirects?

@theiosdevguy Thanks for your patience and welcome to ReactPHP 🎉

The way this API seems to works means you may have to manually follow the redirect by sending a new request to the address given in the Location header. There are plans to support this automatically in the future via #20.

Once you send a request to this ServerSentEvents API, you should see individual chunks coming in via the data events. Parsing this shouldn't be too hard, given that SSE uses a very simple text-based protocol. This implementation is likely out of scope for this project, but we're happy to hear back if you happen to have an implementation for this!

I hope this helps 👍
