Question

我用Python编写了一个简单的代理检查器。我有一个问题-如何加快速度？我试图使用队列和线程，但是没有用。如果可能的话，使用线程库

代码：

import socks

red = "\033[1;31m"
green = "\033[1;32m"
yellow = "\033[1;33m"
blue = "\033[1;34m"
defaultcolor = "\033[0m"

linesinfile = len(open('proxy.txt', 'rU').readlines())

def proxygff():
    global fp
    with open('proxy.txt') as fp:
        pff = fp.readline()
        global cnt
        cnt = 1
        while pff:
            global PROXYIP, PROXYPORT
            PROXYIP, PROXYPORT = pff.split(":")
            pff = fp.readline()
            cnt = cnt + 1
            checkmain()


def savetofile(proxy):
    with open("proxywork.txt", 'a') as file:
        file.write(proxy)


def checkmain():
    try:
        socks.setdefaultproxy(socks.SOCKS5, str(PROXYIP), int(PROXYPORT))
        s = socks.socksocket()
        s.settimeout(1)
        s.connect(("google.com", 80))
        print blue + "Proxy working! " + green + str(cnt) + defaultcolor + "/" + green + str(linesinfile)
        proxy = PROXYIP + ":" + PROXYPORT
        savetofile(proxy)
        s.close()
    except:
        print red + "Proxy not working! " + green + str(cnt) + defaultcolor + "/" + green + str(linesinfile)


proxygff()

用Python 2.7编写

仅当您创建与google.com的连接并等待它们的响应时，Python的多线程才会帮助您。由于GIL，Python解释器一次只运行一个线程。您可以使用asyncio模块（Python> = 3.4）执行相同的操作（避免IO等待）。而且您必须重写代码，因为您为所有打开的套接字全局设置了socks.setdefaultproxy默认代理。
