我是否必须显式释放/取消绑定套接字才能重用它？我正在考虑使用，close()但我已经看到了一些选项，例如tcp.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1). 我必须使用它还是就close()足够了？

有什么方法可以确保该端口可用于新绑定？

TorPorts = {}
def port_setup(workers):
    for worker in range(workers):
        for i in range(2):
            tcp = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
            tcp.bind(('', 0))
            port = tcp.getsockname()[1]
            print("{0} port {1}, tcp {2}".format(i,port,tcp))
            if not TorPorts.has_key(worker):
                TorPorts[worker] = {0:{},1:{}}
            TorPorts[worker][i] = {"port":port,"tcp":tcp}
    # do some programing

    # close ports I s this enough?
    for thread,ports in TorPorts[0].items():
        tcp_port = ports["tcp"]
        tcp_port.close()

我想知道启动驱动程序后如何更新/更改硒中的下载位置？

创建配置文件和启动Webdriver期间设置下载目录不是问题。启动webdriver根据数据类型更改目录后出现问题。

例如，-如果dl doc是Word保存在Docs \ Word中-如果dl doc是pdf保存在Docs \ pdf中

这是我的代码

profile = webdriver.FirefoxProfile()
profile.set_preference('browser.download.dir', os.getcwd())
profile.set_preference("browser.download.folderList", 2)
profile.set_preference('browser.helperApps.neverAsk.saveToDisk', 'application/download,application/octet-stream,application/pdf')
profile.update_preferences()
driver = webdriver.Firefox(firefox_profile=profile)
driver.delete_all_cookies()
sleep(10)
# this part doesn't work
driver.profile.set_preference('browser.download.dir',"{0}\{1}".format(os.getcwd(),"Docs"))
driver.profile.update_preferences()
