Server Side Events (SSE) client for Python
A Python client for SSE event sources that seamlessly integrates with
urllib3 and requests.
Installation
$ pip install sseclient-py
Usage
import json
import pprint
import sseclient
def with_urllib3(url, headers):
"""Get a streaming response for the given event feed using urllib3."""
import urllib3
http = urllib3.PoolManager()
return http.request('GET', url, preload_content=False, headers=headers)
def with_requests(url, headers):
"""Get a streaming response for the given event feed using requests."""
import requests
return requests.get(url, stream=True, headers=headers)
def with_httpx(url, headers):
"""Get a streaming response for the given event feed using httpx."""
import httpx
with httpx.stream('GET', url, headers=headers) as s:
# Note: 'yield from' is Python >= 3.3. Use for/yield instead if you
# are using an earlier version.
yield from s.iter_bytes()
url = 'http://domain.com/events'
headers = {'Accept': 'text/event-stream'}
response = with_urllib3(url, headers) # or with_requests(url, headers)
client = sseclient.SSEClient(response)
