自动检测并更新driver文件,提高selenium代码的稳定性

Project description

介绍

浏览器的更新和driver文件的版本异常,经常是影响代码稳定性的一个原因,而每次driver文件的更新也是比较繁杂的工作,此次的safe-driver意在帮助维护driver的稳定性

作用

safe-driver导入后,可替换selenium的webdriver,使用方式和方法同selenium的webdriver 当启动浏览器driver文件出错时,程序将自动下载并更新浏览器驱动,并重新返回driver,提高代码的稳定性

导入

from SafeDriver.drivers import driver
from SafeDriver.drivers import option

使用

此操作同selenium的webdriver.Chrome()

driver = driver()
driver.get("https://www.baidu.com")

放入options参数

首先确定导入option配置参数 使用同selenium的ChromeOptions,可直接添加,添加后,无需再次写入到driver中

from SafeDriver.drivers import option
option.add_argument('--headless')

路径和系统配置

路径和系统保存在option中,配置需要导入option

from SafeDriver.drivers import option
option.pypath = 'xxx' # python的根目录路径
option.os_ = 'xxx'  # 当前使用的操作系统
option.chromedriver_path = 'xxx'    # 设置chromedriver保存路径

注意事项:

1、option.os_:参数不赋值,则视为自动查找当前操作系统 2、option.pypath:参数不赋值,则视为自动查到python路径(目前自动查找操作系统仅支持windows系统,linux和mac用户请手动配置option.pypath属性) 3、option.chromedriver_path:参数不赋值,则选择option.pypath作为保存路径

目前仅支持chrome浏览器,暂未更新其他浏览器

使用问题快查

在mac和linux上,SafeDriver不好使

SafeDriver自动查找的路径是python的路径,这个查找,在linux和mac上面并不一定能正常进行,linux和mac的用户,最好是手动配置好option.os_和option.pypath

如果更好保持稳定性?

建议代码中,指定driver的保存路径,此时的option.pypath则需要是你保存driver的路径

mac用户不能移动文件

这属于mac系统的限制,某些路径需要进行授权才能访问和显示,所以可以将driver文件放在可直接访问的目录,在代码中设置好driver路径,并将这个路径赋值给option.pypath
