urllib的坑

传输的data做url编码

import urllib.parse as parse
data =parse.quote_plus(formdata).encode(“utf-8”)

火狐缺少geckodriver

国内下载地址
放置于python目录下

常见报错

Expected browser binary location, but unable to find binary in default location……找不到火狐位置，需要

binary = FirefoxBinary('path/to/firefox.exe')
driver = webdriver.Firefox(firefox_binary=binary)
