使用服务连接器集成 Azure Cosmos DB for MongoDB

项目
02/06/2024

本页显示了支持的身份验证方法和客户端，并演示了可用于使用服务连接or 将 Azure Cosmos DB for MongoDB 连接到其他云服务的示例代码。你仍可以使用其他编程语言连接到 Azure Cosmos DB for MongoDB，而无需使用服务连接or。此页面还显示了你在创建服务连接时获得的默认环境变量名称和值（或 Spring Boot 配置）。

受支持的计算服务

服务连接器可用于将以下计算服务连接到 Azure Cosmos DB for MongoDB：

Azure 应用服务
Azure Functions
Azure Container Apps
Azure Spring Apps

受支持的身份验证类型和客户端类型

下表显示了使用服务连接or将计算服务连接到 Azure Cosmos DB for MongoDB 时支持的客户端类型和身份验证方法的组合。 “是”表示支持组合，而“否”则表示不支持该组合。

客户端类型	系统分配的托管标识	用户分配的托管标识	机密/连接字符串	服务主体
.NET	是	是	是	是
Java	是	是	是	是
Java - Spring Boot	否	No	是	否
Node.js	是	是	是	是
Python	是	是	是	是
Go	是	是	是	是
无	是	是	是	是

此表指示支持表中的所有客户端类型和身份验证方法组合，但 Java - Spring Boot 客户端类型除外，后者仅支持 Secret /连接字符串方法。所有其他客户端类型都可以使用任何身份验证方法通过服务连接or连接到 Azure Cosmos DB for MongoDB。

默认环境变量名称或应用程序属性和示例代码

使用以下连接详细信息将计算服务连接到 Azure Cosmos DB。此页面还显示创建服务连接时获得的默认环境变量名称和值（或 Spring Boot 配置），以及示例代码。对于下面每个示例，请将占位符文本 <mongo-db-admin-user>、<password>、<Azure-Cosmos-DB-API-for-MongoDB-account>、<subscription-ID>、<resource-group-name>、<client-secret> 和 <tenant-id> 替换为你自己的信息。有关命名约定的详细信息，检查 Service 连接or internals 一文。

系统分配的托管标识

默认环境变量名称	说明	示例值
AZURE_COSMOS_LISTCONNECTIONSTRINGURL	用户获取连接字符串的 URL	`https://management.azure.com/subscriptions/<subscription-ID>/resourceGroups/<resource-group-name>/providers/Microsoft.DocumentDB/databaseAccounts/<Azure-Cosmos-DB-API-for-MongoDB-account>/listConnectionStrings?api-version=2021-04-15`
AZURE_COSMOS_SCOPE	托管标识范围	`https://management.azure.com/.default`
AZURE_COSMOS_RESOURCEENDPOINT	资源终结点	`https://<Azure-Cosmos-DB-API-for-MongoDB-account>.documents.azure.com:443/`

示例代码

请参阅下面的步骤和代码，使用系统分配的托管标识连接到 Azure Cosmos DB for MongoDB。

安装依赖项

dotnet add package MongoDb.Driver
dotnet add package Azure.Identity

using System.Net.Http;
using System.Security.Authentication;
using System.Security.Cryptography.X509Certificates;
using System.Threading.Tasks;

using Azure.Identity;
using System.Text.Json;

var endpoint = Environment.GetEnvironmentVariable("AZURE_COSMOS_RESOURCEENDPOINT");
var listConnectionStringUrl = Environment.GetEnvironmentVariable("AZURE_COSMOS_LISTCONNECTIONSTRINGURL");
var scope = Environment.GetEnvironmentVariable("AZURE_COSMOS_SCOPE");

// Uncomment the following lines according to the authentication type.

// var tokenProvider = new DefaultAzureCredential();

// For user-assigned identity.
// var tokenProvider = new DefaultAzureCredential(
//     new DefaultAzureCredentialOptions
//     {

// var clientId = Environment.GetEnvironmentVariable("AZURE_COSMOS_CLIENTID");
// var clientSecret = Environment.GetEnvironmentVariable("AZURE_COSMOS_CLIENTSECRET");
// var tokenProvider = new ClientSecretCredential(tenantId, clientId, clientSecret);

// Acquire the access token. 
AccessToken accessToken = await tokenProvider.GetTokenAsync(
    new TokenRequestContext(scopes: new string[]{ scope }));

// Get the connection string.
var httpClient = new HttpClient();
httpClient.DefaultRequestHeaders.Add("Authorization", $"Bearer {accessToken.Token}");
var response = await httpClient.POSTAsync(listConnectionStringUrl);
var responseBody = await response.Content.ReadAsStringAsync();
var connectionStrings = JsonSerializer.Deserialize<Dictionary<string, List<Dictionary<string, string>>>>(responseBody);
string connectionString = connectionStrings["connectionStrings"][0]["connectionString"];

// Connect to Azure Cosmos DB for MongoDB
var client = new MongoClient(connectionString);
