使用MongoDB Atlas时，mongo-go-driver因服务器选择超时而失败

问题描述

开始版本:1.12.5

Go Version: 1.12.5

我有这段代码使用了node.js mongo驱动程序

I have this code which uses the node.js mongo driver

const MongoClient = require('mongodb').MongoClient;
const uri = process.env.MONGO_HOST + "dbname?retryWrites=true";
const client = new MongoClient(uri, {
    useNewUrlParser: true
});

client.connect(async (err) => {
    if (err) {
        throw err
    }
    const collection = client.db("dbname").collection("collectionName");
    const cursor = collection.find()
    await cursor.forEach(console.log)
    // perform actions on the collection object
    client.close();
});

哪个工作正常.

使用 mongo-go-driver ，我这样做:

client, err := mongo.NewClient(options.Client().ApplyURI(os.Getenv("MONGO_HOST") + "dbname?retryWrites=true")
if err != nil {
    panic(err)
}
ctx, _ := context.WithTimeout(context.Background(), 10*time.Second)
err = client.Connect(ctx)
if err != nil {
    panic(err)
}
database := client.Database("dbname")
collection := database.Collection("collectionName")

res, err := collection.Find(context.Background(), bson.M{}, &options.FindOptions{
    Sort: bson.M{
        "priority": -1,
    },
})
if err != nil {
    panic(err)
}
results := make([]structs.ResponseType, 0)
err = res.All(context.Background(), &results)
if err != nil {
    panic(err)
}

但是这样惊慌失措:

panic: server selection error: server selection timeout
current topology: Type: ReplicaSetNoPrimary

我不在容器/泊坞窗中运行它.

I am not running this inside a container/docker.

推荐答案

我遇到了同样的问题，并且已经解决了.如果您有相同的问题，也许我的解决方案会为您提供帮助.尝试在mongo连接网址之后添加参数 connect = direct .

I had the same problem and have solved it. If you have the same question, maybe my solution will help you.Try to add param connect=direct after your mongo connect url.
