前言
笔者使用的mongo驱动是mgo, 这个使用的人比较多，文档也比较齐全
官网地址：http://labix.org/mgo
文档地址：https://godoc.org/labix.org/v2/mgo
源码地址：https://github.com/go-mgo/mgo
1. mgo包安装
go get gopkg.in/mgo.v2
但是貌似现在从gopkg.in下载不了，迂回一下，先从github上下载
go get github.com/go-mgo/mgo
下载好了之后，在$GOPATH/src/下面创建文件夹gopkg.in/mgo.v2, 然后将github.com/go-mgo/mgo的内容，拷贝到gopkg.in/mgo.v2
2. 测试代码
// mongo_test project main.go
package main
import (
"fmt"
"math/rand"
"time"
"gopkg.in/mgo.v2"
"gopkg.in/mgo.v2/bson"
)
type GameReport struct {
// id bson.ObjectId `bson:"_id"`
Game_id int64
Game_length int64
Game_map_id string
}
func err_handler(err error) {
fmt.Printf("err_handler, error:%s\n", err.Error())
panic(err.Error())
}
func main() {
dail_info := &mgo.DialInfo{
Addrs: []string{"127.0.0.1"},
Direct: false,
Timeout: time.Second * 1,
Database: "game_report",
Source: "admin",
Username: "test1",
Password: "123456",
PoolLimit: 1024,
}
session, err := mgo.DialWithInfo(dail_info)
if err != nil {
fmt.Printf("mgo dail error[%s]\n", err.Error())
err_handler(err)
}
defer session.Clone()
// set mode
session.SetMode(mgo.Monotonic, true)
c := session.DB("game_report").C("game_detail_report")
r := rand.New(rand.NewSource(time.Now().UnixNano()))
report := GameReport{
// id: bson.NewObjectId(),
Game_id: 100,
Game_length: r.Int63() % 3600,
Game_map_id: "hello",
}
err = c.Insert(report)
if err != nil {
fmt.Printf("try insert record error[%s]\n", err.Error())
err_handler(err)
}
result := GameReport{}
var to_find_game_id int64 = 100
err = c.Find(bson.M{"game_id": to_find_game_id}).One(&result)
if err != nil {
fmt.Printf("try find record error[%s]\n", err.Error())
err_handler(err)
}
fmt.Printf("res, game_id[%d] length[%d] game_map_id[%s]\n",
to_find_game_id, result.Game_length, result.Game_map_id)
// try find all report
var results []GameReport
err = c.Find(bson.M{}).All(&results)
if err != nil {
fmt.Printf("try game all record of game_detail_report error[%s]\n",
err.Error())
err_handler(err)
}
result_count := len(results)
fmt.Printf("result count: %d\n", result_count)
for i, report := range results {
fmt.Printf("index: %d, report{ game_id: %d, game_length: %d, game_map_id: %s}\n",
i, report.Game_id, report.Game_length, report.Game_map_id)
}
}
这样要注意的一点是 GameReport 里面的字段都要首字母大写，否则不会写入mongo
