Go 操作mongodb

前言

参考地址:https://juejin.cn/post/6908063164726771719

最近学习在go中操作mongodb,了解到主要有第三方mgo和官方mongo-driver两个库使用最多。mgo已经停止维护了,因此选择了mongo-driver。本文记录一些常用的代码操作笔记,以备随时查阅。

安装

# 初始化go模块,取名为mongo-notes
mkdir goMongo && cd goMongo
go mod init mongo-notes

# 获取go mongo模块依赖
go get go.mongodb.org/mongo-driver/mongo

 

项目结构

 

package gmongo

// go mongo 文档 https://juejin.cn/post/6908063164726771719

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

var client *mongo.Client
var collection *mongo.Collection
var ctx = context.TODO()


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

    err = client.Ping(ctx, nil)
    if err != nil {
        log.Fatal(err)
    }

    fmt.Println("Connected to MongoDB!")
    return client
}
