mongodb://username:password@mongodb0.example.com:27017,mongodb1.example.com:27017,mongodb2.example.com:27017/?replicaSet=myRepl 对于副本集模式，需要指定副本集配置中列出的mongod实例的主机名，还需要指定replicaSet选项。分片集群模式的格式为：mongodb://username:password@mongos0.example.com:27017,mong...
连接字符串包含了连接到MongoDB数据库所需的所有信息,如主机名、端口、数据库名称等。例如,要连接到本地运行的MongoDB实例,你可以使用以下连接字符串: go clientOptions := options.Client().ApplyURI("mongodb://localhost:27017") 使用连接字符串建立与MongoDB的连接: 使用mongo.Connect函数和之前创建的连接字符...
2. 连接 MongoDB 数据库 创建一个新的 MongoDB 客户端并连接到数据库。这里是所需的代码: packagemainimport("context""fmt""log""time""go.mongodb.org/mongo-driver/mongo""go.mongodb.org/mongo-driver/mongo/options")funcconnectDatabase()(*mongo.Client,error){// 创建 MongoDB 客户端连接clientOpti...
接下来以标准连接字符串格式来做讲解。 使用Golang连接MongoDB 首先讲下标准连接字符串格式URI,格式为: mongodb://[username:password@]host1[:port1][,...hostN[:portN]][/[defaultauthdb][?options]]

IP is added to the whitelist in your MongoDB Atlas project (see Security -> Network Access). If you deploy the Go service in a Google Kubernetes Engine, you may want to take a look at our next article, which explains how to securely connect a Kubernetes cluster with the MongoDB Atlas....
mongo.Connect()接受Context和options.ClientOptions对象,该对象用于设置连接字符串和其他驱动程序设置。 通过context.TODO()表示不确定现在使用哪种上下文,但是会在将来添加一个 使用Ping方法来检测是否已正常连接MongoDB func main() { clientOptions := options.Client().ApplyURI("mongodb://admin:password@localhost...
