问如何在Golang中将mongodb的命令转换为Bson

package main

import (
    "fmt"
    "gopkg.in/mgo.v2"
    "gopkg.in/mgo.v2/bson"
)

type Person struct {
    Name  string
    Phone string
}

func main() {
    session, err := mgo.Dial("mongodb://localhost")
    if err != nil {
        panic(err)
    }
    defer session.Close()

    // Optional. Switch the session to a monotonic behavior.
    session.SetMode(mgo.Monotonic, true)

    c := session.DB("test").C("people")
    err = c.Insert(&Person{"Alice", "+1234567890"}, &Person{"Bob", "+9876543210"})
    if err != nil {
        panic(err)
    }

    result := Person{}
    err = c.Find(bson.M{"name": "Alice"}).One(&result)
    if err != nil {
        panic(err)
    }

    fmt.Println("Phone:", result.Phone)
}
