Question

有没有办法从加载的配置文件中删除键/值对？

不工作

Answer 1

尝试

delete(viper.Get("path.to.key").(map[string]interface{}), "key")

例子:

[backends]
  [backends.setibe]
    [backends.setibe.servers]
      [backends.setibe.servers.server0]
      url = "http://192.168.1.20:80"
      weight = 1
      [backends.setibe.servers.server1]
      url = "http://192.168.1.21:80"
      weight = 1

删除“backends.setibe.servers.server1”

delete(viper.Get("backends.setibe.servers").(map[string]interface{}), "server2")
