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.gopackage mainimport ( "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.Close() // 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) } }
