[Python知识库]Selenium+ubuntu+firefox找不到profile文件解决

使用的firefox为商店snap安装

Python:
1.在firefox地址栏中输入：about:profiles
2. 创建新配置文件，名称如selenium
3. 取消新配置作为默认配置
4. 将新配置本地目录/home/user/snap/firefox/common/.cache/mozilla/firefox/a1nwuiny.selenium指定给selenium。

from selenium import webdriver
from selenium.webdriver.firefox.options import Options
options = Options()
options.add_argument("-profile")
options.add_argument("/home/user/snap/firefox/common/.cache/mozilla/firefox/a1nwuiny.selenium")
br=webdriver.Firefox(options=options)
br.get(“http://www.baidu.com/”)

如果使用原有的profile给selenium, 当firefox已打开时，会提示已经运行，需要新建profile.

Golang:
golang也需要额外指定profile.
按照https://firefox-source-docs.mozilla.org/testing/geckodriver/Profiles.html的说明，将profile添加到Capablities的Args参数中
原文：

1. by appending --profile /some/location to the args capability, which will instruct geckodriver to use the profile in-place;
2. or by setting the profile capability to a Base64-encoded ZIP of the profile directory.
   第二种方法没成功。
