Question

我一直在尝试连接到 mongodb atlas，但出现以下错误。

auth error: sasl conversation error: unable to authenticate using mechanism "SCRAM-SHA-1": (AtlasError) bad auth : Authentication failed.

我还在 at mongodb atlas GUI 上将我的 IP 列入白名单...

URI 链接适用于 1.0 及更高版本的 go 应用程序

以下是我的代码

package main

import (
    "context"
    "fmt"
    "time"

    "go.mongodb.org/mongo-driver/bson/primitive"
    "go.mongodb.org/mongo-driver/mongo"
    "go.mongodb.org/mongo-driver/mongo/options"
)

const (
    // Name of the database.
    DBName = "Stats"
    // Name of the collections
    notesCollection = "notes"
    URI = "mongodb+srv://<username><password>@inshorts.0wwoh.mongodb.net/myFirstDatabase?retryWrites=true&w=majority"
)

type Note struct {
    ID        primitive.ObjectID `bson:"_id" json:"id,omitempty"`
    Title     string             `json:"title"`
    Body      string             `json:"body"`
    CreatedAt time.Time          `bson:"created_at" json:"created_at,omitempty"`
    UpdatedAt time.Time          `bson:"updated_at" json:"updated_at,omitempty"`
}

func main() {
    ctx := context.Background()
    // Options to the database.
    clientOpts := options.Client().ApplyURI(URI)
    client, err := mongo.Connect(ctx, clientOpts)
    if err != nil {
        fmt.Println(err)
        return
    }
    db := client.Database(DBName)
    coll := db.Collection(notesCollection)
    fmt.Println(coll.Name()) // output: notes

    note := Note{}
    // An ID for MongoDB.
    note.ID = primitive.NewObjectID()
    note.Title = "First note"
    note.Body = "Some spam text"
    note.CreatedAt = time.Now()
    note.UpdatedAt = time.Now()
    result, err := coll.InsertOne(ctx, note)
    if err != nil {
        fmt.Println(err)
        return
    }
    // ID of the inserted document.
    objectID := result.InsertedID.(primitive.ObjectID)
    fmt.Println(objectID)

}

我使用 atlas 是因为我在系统中安装 MongoDB 时遇到问题（我遵循此 https://stackoverflow.com/a/67719154/14409588 ），每当我运行 sudo apt-get install -y mongodb-org 时，我都会收到以下错误

dpkg: unrecoverable fatal error, aborting:

before the override, which is most probably a packaging bug, to recover you
can remove the override manually with dpkg-statoverride
E: Sub-process /usr/bin/dpkg returned an error code (2)

因此，由于我无法安装 mongo，因此我无法通过终端检查 URI 是否确实有效，但我很确定 URI 是正确的，因为它是从 atlas gui 本身复制的
