将MongoDB $max结果转换为golang数据

import (
    "go.mongodb.org/mongo-driver/mongo"
    "go.mongodb.org/mongo-driver/mongo/options"
    "go.mongodb.org/mongo-driver/bson"
)

client, err := mongo.Connect(context.TODO(), options.Client().ApplyURI("mongodb://localhost:27017"))
if err != nil {
    // 处理连接错误
}
database := client.Database("your_database_name")
collection := database.Collection("your_collection_name")

filter := bson.D{{"your_field_name", bson.D{{"$max", 1}}}}
result := collection.FindOne(context.TODO(), filter)

var data YourDataType
err = result.Decode(&data)
if err != nil {
    // 处理解码错误
}
