英文:
connection to remote mongodb server failed in golang, giving authentication error
问题
我正在尝试在Golang中连接到远程MongoDB服务器并向数据库中添加数据。它给我返回以下错误：
服务器在SASL认证步骤上返回错误：认证失败。
代码：
package main
import (
"fmt"
"gopkg.in/mgo.v2"
"gopkg.in/mgo.v2/bson"
"log"
// "os"
)
type Person struct {
Name string
Phone string
}
func main() {
session, err := mgo.Dial("mongodb://<dbuser>:<dbpassword>@ds041154.mongolab.com:41154/location")
if err != nil {
fmt.Println(err)
} else {
fmt.Println("Session created")
}
// Optional. Switch the session to a monotonic behavior.
session.SetMode(mgo.Monotonic, true)
c := session.DB("location").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)
}
希望对你有所帮助。

我遇到了类似的错误，但后来发现我输入了错误的登录凭据。
以下是适用于我的代码：
package main
import (
"fmt"
"time"
"gopkg.in/mgo.v2"
)
// MongoDB的详细信息
const (
hosts = "ds026491.mongolab.com:26491"
database = "messagingdb"
username = "admin"
password = "youPassword"
collection = "messages"
)
func main() {
info := &mgo.DialInfo{
Addrs: []string{hosts},
Timeout: 60 * time.Second,
Database: database,
Username: username,
Password: password,
}
session, err1 := mgo.DialWithInfo(info)
if err1 != nil {
panic(err1)
}
col := session.DB(database).C(collection)
count, err2 := col.Count()
if err2 != nil {
panic(err2)
}
fmt.Println(fmt.Sprintf("Messages count: %d", count))
}
你也可以在Github上找到这段代码。
英文:
I was getting similar error, but I found that I had entered wrong login credentials.
This code worked for me:
package main
import (
"fmt"
"time"
"gopkg.in/mgo.v2"
)
//const MongoDb details
const (
hosts = "ds026491.mongolab.com:26491"
database = "messagingdb"
username = "admin"
password = "youPassword"
collection = "messages"
)
func main() {
info := &mgo.DialInfo{
Addrs: []string{hosts},
Timeout: 60 * time.Second,
Database: database,
Username: username,
Password: password,
}
session, err1 := mgo.DialWithInfo(info)
if err1 != nil {
panic(err1)
}
col := session.DB(database).C(collection)
count, err2 := col.Count()
if err2 != nil {
panic(err2)
}
fmt.Println(fmt.Sprintf("Messages count: %d", count))
}

你需要在需要进行身份验证的数据库上调用.Login(user, pass string)方法：
if err := session.DB(authDB).Login(user, pass); err != nil {
panic(err)
}
请注意，这将对session进行身份验证，因此从它进行.Copy()或.Clone()的任何其他会话也将被身份验证。
英文:
You need to call .Login(user, pass string) on the database you need to authenticate with:
if err:= session.DB(authDB).Login(user, pass); err != nil {
panic(err)
}
Note that this authenticates the session, so each other session you .Copy() or .Clone() from it is also authenticated.
