鱿鱼代理配置允许少量的youtube网址

Question

我想完全禁止youtube.com网站通过squid访问。封锁youtube后，我想允许少数100个youtube的网址通过squid访问。只允许访问教育类的视频。我的squid安装工作正常。但是我在url_regex部分卡住了。我不能允许几个youtube的网址。要么youtube被屏蔽，要么youtube被完全打开。这是我的 sqid 配置文件。

# Only allow cachemgr access from localhost

# Example rule allowing access from your local networks.
# Adapt localnet in the ACL section to list your (internal) IP networks

http_access allow localnet
http_access allow localhost

# And finally deny all other access to this proxy
http_access deny all

# Squid normally listens to port 3128
http_port 3128

# Uncomment and adjust the following to add a disk cache directory.
cache_dir ufs /var/spool/squid 512 16 256

# Leave coredumps in the first cache dir
coredump_dir /var/spool/squid

#
# Add any of your own refresh_pattern entries above these.

允许的视频文件的内容如下.youtube.comwatch?v=6tO_isJQfCY。

被屏蔽的网站文件内容如下.youtube.com。

请帮助我，使我可以部分地允许通过鱿鱼访问YouTube视频。

• 你不能使用Squid Proxy作为防火墙进行内容过滤。
• 鱿鱼浏览器 是很好的，谁想要过滤大量的URLS和网站与一个DB文件。
• url_regex 对你来说不是好事，因为Youtube频道中含有未知字符。

因此，你应该使用一些应用程序或用Python开发代码来检查整个网站的内容，使其允许或拒绝你的客户。

但在这种情况下，我建议你手动允许URL（如白名单）。

这是你想要的示例代码。

• 首先将URLS保存在文件中："etcsquidmywhitelist.txt"

• 那么你就应该像这段代码一样只允许你的客户使用这个文件。

acl youtube_access src "/etc/squid/mywhitelist.txt"
http_access allow youtube_access
http_access deny all
