Manipulating mongodb's bson.D output format - json

Question

Im using FindOne to query one row of data (single document):
package main
import (
"context"
"fmt"
"github.com/fatih/color"
"go.mongodb.org/mongo-driver/bson"
"go.mongodb.org/mongo-driver/mongo"
"go.mongodb.org/mongo-driver/mongo/options"
)
func mongoDbFindOne(key, value string) bson.D {
var result bson.D
_ = Collection.FindOne(context.TODO(), bson.D{{key, value}}).Decode(&result)
color.Green("[+] Found: %+v\n", result)
return result
}
And this a small part of how the result is shown:
[
{
"Key": "_id",
"Value": "1600540844649"
},
{
"Key": "hostname",
"Value": "DESKTOP-xxxxxx"
},
{
"Key": "cmdLine",
"Value": []
},
{
"Key": "pid",
"Value": 4816
}
]
But this how i want it to be:
[
{
"_id": "1600540844649"
},
{
"hostname": "DESKTOP-xxxxxx"
},
{
"cmdLine": []
},
{
"pid": 4816
}
]
Or:
[
{
"_id": "1600540844649",
"hostname": "DESKTOP-xxxxxx",
"cmdLine": [],
"pid": 4816,
}
]
What should i do? I have searched through SO and google but no luck. Should i use struct or creating any objects? I also searched for saving/converting bson to json but there is solution to it.

Answer 1

I found the solution myself:
Using bson.M instead of bson.D solved my issue:
import (
"context"
"fmt"
"github.com/fatih/color"
"go.mongodb.org/mongo-driver/bson"
"go.mongodb.org/mongo-driver/mongo"
"go.mongodb.org/mongo-driver/mongo/options"
)
func mongoDbFindOne(key, value string) bson.M {
var result bson.M
_ = Collection.FindOne(context.TODO(), bson.M{key:value}).Decode(&result)
color.Green("[+] Found: %+v\n", result)
return result
}
