Go JSON元帅的默认案例选项？

Question

I have the following structures to export onto json:

type ExportedIncident struct {
    Title      string `json:"title"`
    Host       string `json:"host"`
    Status     string `json:"status"`
    Date       string `json:"date"`
    Notes      []ExportedNote `json:"notes"`
    LogEntries []ExportedLogEntry `json:"log_entries"`
}

And I want underscore cased fields, so I had to define each field just for that as described in this answer: https://stackoverflow.com/a/11694255/1731473

But it's really cumbersome and I believe there is a simpler solution in Go, but I can't find it.

How can I set default letter-case (underscore, snake, camel...) for JSON export?

Unfortunately there are no opportunities to export your fields into snake_case so you have to maintain tags by yourself.

Technically you can use method MarshalJSON and perform all manipulations inside this method, but it isn't easier way...
