Print collection in a list of a collection in mongodb in golang

Issue

To print a collection from mongodb the following is my code in python:

print(list(MongoClient(***).get_database("ChatDB").get_collection("room_members".find({'_id.username': username})))

I am learning Go and I am trying to translate the aforementioned code into golang.

My code is as follows:

    client, err := mongo.Connect(context.TODO(), options.Client().ApplyURI("*****"))
    if err != nil {
        panic(err)
    }
    likes_collection := client.Database("ChatDB").Collection("likes")
    cur, err := likes_collection.Find(context.Background(), bson.D{{}})
    if err != nil {
        panic(err)
    }
    defer cur.Close(context.Background())
    fmt.Println(cur)

However, I get some hex value

Solution

Mongo in go lang different api than mongo.

Find returns cursor not collection.

You should changed your code to :

var items []Items 
cur, err := likes_collection.Find(context.Background(), bson.D{{}})
    if err != nil {
        panic(err)
    }
cur.All(context.Background(),&items)
