Is it possible to set the system proxy from golang app in macOS or Linux distributes?
问题
你好！你想在你的golang应用程序中创建一个代理服务器，并且希望能够将其设置为系统代理。这是可能的吗？如何实现呢？

代理通常通过HTTP_PROXY、HTTPS_PROXY和NO_PROXY环境变量进行配置。在类Unix操作系统中，这些变量会从父进程继承给其子进程。
话虽如此：
- 您的程序可以修改自己的环境并启动其他进程作为子进程（传递
_PROXY变量）。 - 您的程序可以修改shell启动脚本（如
.bashrc、.cshrc），新启动的shell将获取这些值并将它们传递给新启动的进程。
但我不知道修改其他（活动的）进程的环境是否可行。
英文:
Proxies are often configured through the HTTP_PROXY, HTTPS_PROXY and NO_PROXY environment variables. In Unix-style operating systems, these variables are inherited from the parent process to its child processes.
This being said:
- your program can modify its own environment and start other processes as child processes (passing in the
_PROXYvariables). - your program may modify the shell startup scripts (like
.bashrc,.cshrc), and a newly started shell will pick the values up and pass them to newly started processes.
But I am not aware that modifying the environment of other (active) processes is possible.
