MongoDB

Overview

mgo is a simple wrapper library based on the official MongoDB Go Driver.

MongoDB Configuration

Enable MongoDB support in the YAML configuration file under the configs directory:

# database setting
database:
  driver: "mongodb"
  mongodb:
    # dsn format,  <username>:<password>@<hostname1>:<port1>[,<hostname2>:<port2>,......]/<db>?[k=v& ......]
    dsn: "root:123456@192.168.3.37:27017/account?connectTimeoutMS=15000"

MongoDB Initialization

    import "github.com/go-dev-frame/sponge/pkg/mgo"

    // dsn document: https://www.mongodb.com/docs/manual/reference/connection-string/

    // case 1: specify options in dsn
    db, err := mgo.Init("mongodb://root:123456@192.168.3.37:27017/account?socketTimeoutMS=30000&maxPoolSize=100&minPoolSize=1&maxConnIdleTimeMS=300000")

    // case 2: specify options in code
    db, err := mgo.Init("mongodb://root:123456@192.168.3.37:27017/account",
        mgo.WithOption().SetMaxPoolSize(100),
        mgo.WithOption().SetMinPoolSize(1),
        mgo.WithOption().SetMaxConnIdleTime(5*time.Minute),
        mgo.WithOption().SetSocketTimeout(30*time.Second),
    )

    // close mongodb
    defer mgo.Close(db)
