Cobra 和 Viper 中的文档让我感到困惑。我做到了cobra init fooproject然后在我做的项目目录中cobra add bar。我有一个PersistentFlag那个被命名为foo这是来自的 init 函数root命令。
func Execute() {
if err := RootCmd.Execute(); err != nil {
fmt.Println(err)
os.Exit(-1)
}
fmt.Println(cfgFile)
fmt.Println("fooString is: ", fooString)
}
func init() {
cobra.OnInitialize(initConfig)
// Here you will define your flags and configuration settings.
// Cobra supports Persistent Flags, which, if defined here,
// will be global for your application.
RootCmd.PersistentFlags().StringVar(&cfgFile, "config", "", "config file (default is $HOME/.fooproject.yaml)")
RootCmd.PersistentFlags().StringVar(&fooString, "foo", "", "loaded from config")
viper.BindPFlag("foo", RootCmd.PersistentFlags().Lookup("foo"))
// Cobra also supports local flags, which will only run
// when this action is called directly.
RootCmd.Flags().BoolP("toggle", "t", false, "Help message for toggle")
}
我的配置文件看起来像这样......

foo: aFooString
当我打电话时go run main.go我看到这个...
A longer description that spans multiple lines and likely contains
examples and usage of using your application. For example:
Cobra is a CLI library for Go that empowers applications.
This application is a tool to generate the needed files
to quickly create a Cobra application.
Usage:
fooproject [command]
Available Commands:
bar A brief description of your command
help Help about any command
Flags:
--config string config file (default is $HOME/.fooproject.yaml)
--foo string loaded from config
-h, --help help for fooproject
-t, --toggle Help message for toggle
Use "fooproject [command] --help" for more information about a command.
fooString is:
当我打电话时go run main.go bar我看到这个...
Using config file: my/gopath/github.com/user/fooproject/.fooproject.yaml

所以它正在使用配置文件，但它们似乎都没有读取它。也许我误解了 Cobra 和 Viper 的工作方式。有任何想法吗？
