使用Golang在MongoDB中更新无循环的文档

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

clientOptions := options.Client().ApplyURI("mongodb://localhost:27017")
client, err := mongo.Connect(context.TODO(), clientOptions)
if err != nil {
    log.Fatal(err)
}

collection := client.Database("your_database").Collection("your_collection")

filter := bson.D{{"field1", "value1"}} // 更新条件，可以根据具体需求修改
update := bson.D{{"$set", bson.D{{"field2", "value2"}}}} // 更新内容，可以根据具体需求修改

updateResult, err := collection.UpdateOne(context.TODO(), filter, update)
if err != nil {
    log.Fatal(err)
}

fmt.Printf("Matched %v document(s) and updated %v document(s)\n", updateResult.MatchedCount, updateResult.ModifiedCount)
