在proto3文件中将IP字段（IPV4或IPV6）用于Golang和C＃的更好方法是什么

问题描述：

I want to use an IP field in a proto3 message. Which type in proto3 should I use to represent the same. The field will be used by Golang and C# implementation. Should I use string? or fixed32 for IPV4 and bytes for IPV6?

message xyz {
  string ip_addr = 1;
}

message xyz {
    oneof ip_addr{
       fixed32 v4 = 1;
       bytes v6 = 2;
}

If it is the second one, then how to encode that in Golang implementation? Like, should I first construct a string with a valid IP address and then convert it to fixed32 format or how is it?

我想在proto3消息中使用IP字段。我应该使用proto3中的哪种类型来表示相同的类型。该字段将由Golang和C＃实现使用。我应该使用字符串吗？或fixed32（对于IPV4）和字节（对于IPV6）？ p>

 消息xyz {
字符串ip_addr = 1; 
} 
  code>  pre> 
 
 或 p> \  n 
 
 消息xyz {
 ip_addr中的一个{
 fixed32 v4 = 1; 
字节v6 = 2; 
} 
  code>  pre> 
 
 如果是第二个，那么如何在Golang实现中对其进行编码？ 就像，我应该先用有效的IP地址构造一个字符串，然后将其转换为fixed32格式还是如何？ p>

答

If you have no performance constraints here, I would just go with a string.

Almost any language has support for reading an ip address from a string with standard ipv4 or ipv6 notation. If you use a binary representation in a fixed32 or bytes field, you'll have to figure out a way to convert that in each language you use your protocol with.

You may also want to specify whether it always has to be an ip address, or if a DNS hostname could be used instead.
