# add the push_stream_shared_memory_size to your http context
http {
push_stream_shared_memory_size 32M;
# define publisher and subscriber endpoints in your server context
server {
location /channels-stats {
# activate channels statistics mode for this location
push_stream_channels_statistics;
# query string based channel id
push_stream_channels_path $arg_id;
}
location /pub {
# activate publisher (admin) mode for this location
push_stream_publisher admin;
# query string based channel id
push_stream_channels_path $arg_id;
}
location ~ /sub/(.*) {
# activate subscriber (streaming) mode for this location
push_stream_subscriber;
# positional channel path
push_stream_channels_path $1;
}
}
}
You can feel the flavor right now at the command line. Try using more than
one terminal and start playing http pubsub:
# Subs
curl -s -v --no-buffer 'http://localhost/sub/my_channel_1'
curl -s -v --no-buffer 'http://localhost/sub/your_channel_1'
curl -s -v --no-buffer 'http://localhost/sub/your_channel_2'
# Pubs
curl -s -v -X POST 'http://localhost/pub?id=my_channel_1' -d 'Hello World!'
curl -s -v -X POST 'http://localhost/pub?id=your_channel_1' -d 'Hi everybody!'
curl -s -v -X POST 'http://localhost/pub?id=your_channel_2' -d 'Goodbye!'
# Channels Stats for publisher (json format)
curl -s -v 'http://localhost/pub?id=my_channel_1'
# All Channels Stats summarized (json format)
curl -s -v 'http://localhost/channels-stats'
# All Channels Stats detailed (json format)
curl -s -v 'http://localhost/channels-stats?id=ALL'
# Prefixed Channels Stats detailed (json format)
curl -s -v 'http://localhost/channels-stats?id=your_channel_*'
# Channels Stats (json format)
curl -s -v 'http://localhost/channels-stats?id=my_channel_1'
# Delete Channels
curl -s -v -X DELETE 'http://localhost/pub?id=my_channel_1'
