Golang获取特定结构字段名称的字符串表示(Golang get string representation of specific struct field name)

I really want a way to print the string representation of a field name in go. It has several use cases, but here is an example:

lets say I have a struct

type Test struct {
    Field      string `bson:"Field" json:"field"`
    OtherField int    `bson:"OtherField" json:"otherField"`
}

and, for example, I want to do a mongo find:

collection.Find(bson.M{"OtherField": someValue})

I don't like that I have to put the string "OtherField" in there. It seems brittle and easy to either misstype or have the struct change and then my query fails without me knowing it.

Is there any way to get the string "OtherField" without having to either declare a const or something like that? I know I can use reflection to a get a list of field names from a struct, but I'd really like to do something along the lines of

fieldName := nameOf(Test{}.OtherField) 
collection.Find(bson.M{fieldName: someValue})

is there any way to do this in Go?? C# 6 has the built in nameof, but digging through reflection I can't find any way to do this in Go.
