Question

美好的一天，我是python的新手，我已经尽力在下面构建代码：

import http.client
import random
import string
import multiprocessing

def worker():
    """worker function"""
    if res.status == 200:
        print("Valid key found: " + key + " Got status: ", + res.status)
    elif res.status == 302:
        print("invalid key! " + key + "!")
    return

def randomStringDigits(stringLength=6):
    """Generate a random string of letters and digits """
    lettersAndDigits = string.ascii_letters + string.digits
    return ''.join(random.choice(lettersAndDigits) for i in range(stringLength))

key = randomStringDigits(14);

conn = http.client.HTTPSConnection("www.pra1ser.com", timeout=10)

payload = "comment_text=%40asnikuwait1%20test2&replied_to_comment_id="

headers = {
    'cookie': "md5=5; prm_124024574287414=base_domain=api.pra1ser.com; csrftoken=5es0TEJiV6JOOjEzqyAfyeyN1FtnRIi1; session=CVzZzZz%3A" + key + "%3A8;",
    'x-csrftoken': "5es0TEJiV6JOOjEzqyAfyeyN1FtnRIi1",
    'content-type': "application/x-www-form-urlencoded"
    }

conn.request("POST", "/web/comments/2050815839087051573/add/", payload, headers)

res = conn.getresponse()
data = res.read()

#print(data.decode("utf-8"))
#print(headers)
#print(res.status)

if __name__ == '__main__':
    jobs = []
    for i in range(100):
        p = multiprocessing.Process(target=worker)
        jobs.append(p)
        p.start()

我想让它无限多地工作，可以容纳100个工人，直到它从服务器获得响应“ 200”，然后它就中断了。

我曾经尝试过，但我破坏了代码，出现了很多错误。而且我尝试了无限循环，但尝试失败。

我希望有人能帮助我。

谢谢你，问候。 pra1

当您使用多进程时，没有必要使用循环（可能会使整个过程变慢），实现您想要的多进程的最简单方法是使用with语句，我不是可以尝试执行此操作，因为我不知道您要尝试访问的真实网站，但它应该看起来像这样：

from concurrent.futures import ThreadPoolExecutor

... 
...

def worker(con):
    """worker function"""
    while res.status != 200:
        res = conn.getresponse()
        if res.status == 200:
            return "Valid key found: " + key + " Got status: ", + res.status
        elif res.status == 302:
            print( "invalid key! " + key + "!")

...

with ThreadPoolExecutor(max_workers=100) as pool:
        results = pool.map(worker, res)
