连接字符串(Connection Strings)

➤ 使用右上角的 Select your language（选择语言）下拉菜单，设置以下示例的语言。

您可以使用连接字符串来定义 MongoDB 实例与以下目标之间的连接：

  • 您的应用程序，当您使用驱动程序进行连接时。

  • MongoDB Compass 和 MongoDB Shell (mongosh) 等工具。

完成如下步骤，找到您的连接字符串。

查找您的 MongoDB Atlas 连接字符串

要使用 Atlas CLI 查找 MongoDB Atlas 连接字符串，请安装 Atlas CLI 并通过其进行连接，然后运行以下命令。将 <clusterName> 替换为 MongoDB Atlas 集群的名称，并将 <projectId> 替换为项目 ID。

atlas clusters connectionStrings describe <clusterName> --projectId <projectId>

要了解更多信息，请参阅 atlas 集群资源 connectionStrings 描述。

要在 Atlas 用户界面中查找 MongoDB Atlas 连接字符串，请按照以下步骤操作：

1

在 MongoDB Atlas 用户界面中，转到项目的 Clusters（集群）页面。

警告

导航改进正在进行中

我们目前正在推出改进的全新导航体验。如果以下步骤与Atlas用户界面中的视图不匹配，请参阅Atlas预览文档。

  1. 如果尚未显示，请从导航栏上的 Organizations 菜单中选择包含所需项目的组织。

  2. 如果尚未显示，请从导航栏的 Projects 菜单中选择您的项目。

  3. 如果尚未出现，请单击侧边栏中的 Clusters（集群）。

    会显示集群页面。

2

打开 Connection Method（连接方式）对话框。

  1. 单击要连接的集群所对应的 Connect。

  2. 单击 Choose a Connection Method。MongoDB Atlas 默认选择Standard Connection。要使用私有端点进行连接，请选择 Private Endpoint。

3

选择连接方法。

要连接到您的应用程序，请单击 Drivers。要使用工具进行连接，请单击要用来访问数据的工具。

4

按照您选择的连接方法的说明进行操作。

  1. 如果您选择了 Drivers，请选择您的驱动程序和版本。如果您选择了工具，请下载相应工具。

  2. 选择 Connect To Cluster 。

  3. 复制连接字符串。将连接字符串中的 <password> 和 <username> 替换为数据库用户的凭证。

您的 MongoDB Atlas 连接字符串将类似于以下示例：

mongosh "mongodb+srv://cluster0.example.mongodb.net myFirstDatabase" --apiVersion 1 --username myDatabaseUser
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/?retryWrites=true&w=majority
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/?retryWrites=true&w=majority
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/?retryWrites=true&w=majority
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/?retryWrites=true&w=majority
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/?retryWrites=true&w=majority
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/?retryWrites=true&w=majority
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/?retryWrites=true&w=majority
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/?retryWrites=true&w=majority

查找自托管部署的连接字符串

如果您已连接到自托管的MongoDB Enterprise或MongoDB Community部署，运行db.getMongo() 方法以返回连接字符串。

如果您未连接到部署，则可以根据要使用的连接类型确定连接字符串。 请参阅 SRV 连接格式，学习；了解SRV连接字符串语法，或参阅标准连接字符串格式，学习；了解标准连接字符串语法。

您的自托管连接字符串将类似于以下示例：

以下副本集连接字符串包含这些元素：

mongosh "mongodb+srv://mongodb0.example.com/?authSource=admin&replicaSet=myRepl" --apiVersion 1 --username myDatabaseUser
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@mongodb0.example.com/?authSource=admin&replicaSet=myRepl
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@mongodb0.example.com/?authSource=admin&replicaSet=myRepl
