Python: using httplib2 and ThreadPoolExecutor to create a large number of concurrent HTTP requests

concurrent-http.py

import httplib2
import concurrent.futures

EMPTY_REQ_BODY = body = ""
URI = "http://0.0.0.0:8001/admin/v1/timestamp"
REQ_HEADERS = headers = {'Accept': 'text/plain'}

EXECUTOR = concurrent.futures.ThreadPoolExecutor(max_workers=64)


def print_http_response(num):
    h = httplib2.Http()
    h.add_credentials('q', 'q')
    response_header, response_body = h.request(URI, "GET", EMPTY_REQ_BODY, REQ_HEADERS)
    print(num, response_header.status, response_body)

for i in range(1000):
    EXECUTOR.submit(print_http_response, i)
