Multi-threaded http stress test code implemented by Python

This article mainly introduces the multi-threaded http stress testing code implemented by Python, and analyzes the implementation skills related to Python multi-threaded operations in the form of examples, for more information, see the example in this article to describe the multi-threaded http stress test code implemented by Python. We will share this with you for your reference. The details are as follows:

# Python version 3.3__author__ = 'Toil'import sys, getoptimport threadingdef httpGet(url, file):  import http.client  conn = http.client.HTTPConnection(url)  conn.request("GET", file)  r = conn.getresponse()  #print(r.getheaders())  while not r.closed:    r.read(200)  conn.close()def Usage():  print('''  Options are:  -c concurrency Number of multiple requests to make  -u host     The host  -f file     File on web  Example: httpget.py -c 100 -u www.example.com -f /  ''')if __name__ == '__main__':  opts, args = getopt.getopt(sys.argv[1:], "hc:u:f:")  global u, c, f  for op, value in opts:    if op == '-c':      c = int(value)    elif op == '-u':      u = value    elif op == '-f':      f = value    elif op == '-h':      Usage()      sys.exit(0)    else:      sys.exit(0)  threads = []  times = c  print('Test for ', u, f)  print('waiting...')  for i in range(0, times):    t = threading.Thread(target=httpGet(u, f))    threads.append(t)  for i in range(0, times):    threads[i].start()  for i in range(0, times):    threads[i].join()

I hope this article will help you with Python programming.
