进入golang的MongoDB切片查询

import "go.mongodb.org/mongo-driver/mongo"
import "go.mongodb.org/mongo-driver/mongo/options"

client, err := mongo.NewClient(options.Client().ApplyURI("mongodb://localhost:27017"))
if err != nil {
    // 处理错误
}
ctx := context.TODO()

err = client.Connect(ctx)
if err != nil {
    // 处理错误
}
defer client.Disconnect(ctx)

collection := client.Database("your-database").Collection("your-collection")
filter := bson.D{{"field", "value"}}

options := options.Find()
options.SetSkip(0) // 设置查询起始位置
options.SetLimit(10) // 设置查询结果数量
cur, err := collection.Find(ctx, filter, options)
if err != nil {
    // 处理错误
}
defer cur.Close(ctx)

for cur.Next(ctx) {
    var result bson.M
    err := cur.Decode(&result)
    if err != nil {
        // 处理错误
    }
    // 处理查询结果
}
if err := cur.Err(); err != nil {
    // 处理错误
}
