A rich mongodb driver based on mgo and auto refresh when "Closed explicitly" or "EOF"
- do not need
copy := session.Clone; defter copy.Close(); - use db instance in project
- less tcp connections
- auto refresh connections when connection is break
- more simple
if you use copy := session.Clone; defter copy.Close(); copy.DB("dbname).C("col").Find(...)
you may got "Closed explicitly" or "EOF" when in high concurrency
type Person struct {
Name string
Phone string
}
func main() {
//the test is default db
db, err := mdb.Dial("mongodb://127.0.0.1:27017/test")
if err != nil {
panic(err)
}
defer db.Close()
c := db.C("people")
err = c.Insert(&Person{"Ale", "+55 53 8116 9639"},&Person{"Cla", "+55 53 8402 8510"})
if err != nil {
log.Fatal(err)
}
result := Person{}
err = c.Find(bson.M{"name": "Ale"}).One(&result)
if err != nil {
log.Fatal(err)
}
fmt.Println("Phone:", result.Phone)
}use mongo-connection-string + &db={db_name} use to config your db name
example:
db, err := mdb.Dial("mongodb://username:password@192.168.31.5:27017?db=test")when username is not an administrator
db, err := mdb.Dial("mongodb://username:password@127.0.0.1:27017/test")
//when you have to connect another db first
db, err := mdb.Dial("mongodb://username:password@127.0.0.1:27017/db_for_connect?db=test")maxRetries : max retries time when network is error, default is 2
db : database name when your connection string and database name is different
FULL Example:
db, err := mdb.Dial("mongodb://username:password@127.0.0.1:27017?db=test&maxRetries=2")
