tips:blog.51cto.com/fei007/1166… (1)在vim中,进入命令模式输入:set paste,在进行粘贴,就不会乱码了。但是这样存在一个问题,就是不会自动产生缩进了,因此需要在粘贴完成之后命了输入:set nopaste,恢复缩进模式。

4、代码测试

# 单进程
from selenium import webdriver
from loguru import logger
from concurrent.futures import ProcessPoolExecutor

firefox_options = webdriver.FirefoxOptions()


def get_title(link):
    firefox_options = webdriver.FirefoxOptions()
    with webdriver.Remote(
            command_executor='http://10.89.104.53:4444/wd/hub',
            options=firefox_options
    ) as driver:
        driver.get(link)
        logger.info(driver.title)


# 单进程
for i in range(20):
    link = f"https://www.bing.com/search?q={i}&mkt=zh-CN"
    get_title(link)

# 多进程
# pool = ProcessPoolExecutor(8)
# for i in range(20):
#     link = f"https://www.bing.com/search?q={i}&mkt=zh-CN"
#     pool.submit(get_title, link)
