在沙箱环境内设置代理：

gsettings set org.gnome.system.proxy mode manual
# 设置 HTTP 代理
gsettings set org.gnome.system.proxy.http host localhost
gsettings set org.gnome.system.proxy.http port 端口号
# 设置 HTTPS 代理
gsettings set org.gnome.system.proxy.https host localhost
gsettings set org.gnome.system.proxy.https port 端口号

gsettings set org.gnome.system.proxy.socks host localhost
gsettings set org.gnome.system.proxy.socks port 端口号

gsettings set org.gnome.system.proxy mode manual
gsettings set org.gnome.system.proxy.http host localhost
gsettings set org.gnome.system.proxy.http port 7890
gsettings set org.gnome.system.proxy.https host localhost
gsettings set org.gnome.system.proxy.https port 7890
gsettings set org.gnome.system.proxy.socks host localhost
gsettings set org.gnome.system.proxy.socks port 7890
