英文:
Convert golang protobuf enum from int32 to string
问题
我正在面临一个问题，我定义了一个枚举类型的protobuf，但它的值是int32类型的。现在我想以某种方式将所有的protobuf定义更改为字符串类型，或者在不更改protobuf的情况下进行任何代码修改。
枚举定义如下：
enum TimeUnit {
seconds = 0;
minutes = 1;
hours = 2;
days = 3;
months = 4;
}
message CacheDuration {
uint32 Value = 1;
TimeUnit Units = 2;
}
我从生成的代码中得到的结果是：
这是前端要使用的返回值。所以他们会看到Units的值是int32类型的，就像这样：
服务之间通过生成的结构化protobuf进行通信。
我想将其更改为：
"Units":"days"
谢谢。
英文:
I am facing with the problem that protobuf I defined enum but its value is int32
Now I want someway or somehow to change all the protobuf defined to string
Or any code-hack for doing it in gateway without changing the protobuf.
Enum defined
enum TimeUnit {
seconds = 0;
minutes = 1;
hours = 2;
days = 3;
months = 4;
}
message CacheDuration {
uint32 Value = 1;
TimeUnit Units = 2;
}
What i got from generated code now is
And it is the return value for front end to use. So they would see the value of Units = int32 like this:
The services communicate by generated struct protobuf.
I want to make it change to
"Units":"days"
Thanks

你可以在你的Go代码中使用String方法：
generatedTimeUnitEnum.String() // 输出：days
英文:
You can use String method in your go code:
generatedTimeUnitEnum.String() // output: days
