how to use different config files on build?
问题
我有一个用于我的Go程序的配置文件，在本地运行和在服务器上运行时，它的值明显不同。
我的老板最近要求我切换部署方法，即在本地运行"go build"，然后部署该构建版本。因此，我需要每次构建时切换我的全局配置文件。
不幸的是，我记性很差，我几乎肯定会忘记切换这些文件。如果有一种方法（可能是在构建脚本文件中或其他任何地方）可以在构建时使用不同的配置文件，而不是像我在本地开发时通常做的那样运行"go run main.go"，那就太好了。
有人有任何想法或最佳实践吗？
注意：我已经将这个文件添加到了gitignore中，但由于构建基本上将整个程序（包括这些设置变量）固化到一个单独的文件中，只有在服务器上有另一个文件是不够的。
谢谢大家！
英文:
I have a config file for my go program, and clearly it has different values when I run locally vs on my server.
My boss recently asked me to switch deployment methods so that I run "go build" locally, and then deploy that build. Thus, I need to switch out my global config file each time I build.
Unfortunately, I have a piss poor memory, and I'll almost certainly forget to switch these files out. I would love if there were way (maybe in a build script file, or anything) to use different config file when building as opposed to running "go run main.go" as I usually do when I am working locally on development.
Does anyone have any ideas or best practices here?
Note: I already gitignore this file, but since building if basically solidifies the whole program (including these set variables) into a single file, just having another file on the server wouldn't do.
Thanks all!

使用构建约束。
以下是一个示例：
config.go
//go:build !live
// 在这里添加你的本地配置
config_live.go
//go:build live
// 在这里添加你的服务器配置
使用go build来构建本地版本。使用go build -tags live来构建服务器版本。
英文:
Use build constraints.
Here's an example:
config.go
//go:build !live
// Add your local config here
config_live.go
//go:build live
// Add your server config here
Use go build to build the local version. Use go build -tags live to build the server version.
