实战：构建云原生ASP.NET Core应用
项目初始化与依赖配置
// Program.cs - 现代化最小API配置
var builder = WebApplication.CreateBuilder(args);
// Azure服务集成配置
builder.Services.AddAzureClients(clientBuilder =>
{
clientBuilder.AddBlobServiceClient(builder.Configuration.GetSection("AzureStorage"));
clientBuilder.AddTableServiceClient(builder.Configuration.GetSection("AzureStorage"));
});
// 添加健康检查
builder.Services.AddHealthChecks()
.AddAzureBlobStorage(builder.Configuration.GetConnectionString("AzureStorage"));
var app = builder.Build();
// 健康检查端点
app.MapHealthChecks("/health");
// API路由
app.MapGet("/api/products", async (BlobServiceClient blobService) =>
{
var container = blobService.GetBlobContainerClient("products");
await container.CreateIfNotExistsAsync();
var blobs = container.GetBlobsAsync();
return Results.Ok(await blobs.ToListAsync());
});
app.Run();
appsettings.json 云配置
{
"AzureStorage": {
"connectionString": "UseDevelopmentStorage=true", // 开发环境
"blobServiceUrl": "https://{account}.blob.core.windows.net/"
},
"KeyVault": {
"vaultUrl": "https://{vault-name}.vault.azure.net/"
},
"Logging": {
"ApplicationInsights": {
"InstrumentationKey": "{instrumentation-key}"
}
}
}
Azure身份认证与安全集成
认证流程示意图
代码实现：安全密钥管理
// Key Vault集成示例
builder.Configuration.AddAzureKeyVault(
new Uri(builder.Configuration["KeyVault:VaultUrl"]),
new DefaultAzureCredential());
// 使用托管身份认证
var credential = new DefaultAzureCredential();
var secretClient = new SecretClient(
new Uri("https://myvault.vault.azure.net/"),
credential);
// 安全获取连接字符串
var connectionString = await secretClient
.GetSecretAsync("DatabaseConnectionString");
数据持久化方案比较
关系型数据库：Azure SQL + EF Core
// Startup配置
builder.Services.AddDbContext<AppDbContext>(options =>
options.UseSqlServer(
builder.Configuration.GetConnectionString("AzureSql"),
sqlOptions => sqlOptions.EnableRetryOnFailure()));
// 数据模型
public class Product
{
public int Id { get; set; }
public string Name { get; set; }
public decimal Price { get; set; }
public DateTime CreatedAt { get; set; } = DateTime.UtcNow;
}
// 仓储模式实现
public class ProductRepository
{
private readonly AppDbContext _context;
public async Task<Product> CreateAsync(Product product)
{
_context.Products.Add(product);
await _context.SaveChangesAsync();
return product;
}
}
NoSQL方案：Cosmos DB集成
// Cosmos DB配置
builder.Services.AddCosmosRepository(options =>
{
options.CosmosConnectionString =
builder.Configuration.GetConnectionString("CosmosDB");
options.DatabaseId = "ProductDatabase";
options.ContainerPerItemType = true;
});
// 文档模型
[Container("products")]
public class ProductDocument : Item
{
public string Name { get; set; }
public decimal Price { get; set; }
public string Category { get; set; }
}
消息驱动架构实现
Service Bus消息处理
// 消息发送端
public class OrderService
{
private readonly ServiceBusSender _sender;
public async Task PlaceOrderAsync(Order order)
{
var message = new ServiceBusMessage(JsonSerializer.Serialize(order));
await _sender.SendMessageAsync(message);
}
}
// 消息处理端
[FunctionName("ProcessOrder")]
public static async Task Run(
[ServiceBusTrigger("orders", Connection = "ServiceBusConnection")]
ServiceBusReceivedMessage message,
ILogger log)
{
var order = JsonSerializer.Deserialize<Order>(message.Body.ToString());
log.LogInformation($"Processing order {order.Id}");
// 业务逻辑处理
await ProcessOrderAsync(order);
}
部署与 DevOps 流水线

name: appName
location: location
properties: {
serverFarmId: appServicePlan.id
siteConfig: {

}
}
}
监控与诊断最佳实践
Application Insights 集成
// 添加应用监控
builder.Services.AddApplicationInsightsTelemetry(options =>
{
options.ConnectionString = builder.Configuration["ApplicationInsights:ConnectionString"];
});
// 自定义遥测
var telemetryClient = new TelemetryClient();
telemetryClient.TrackEvent("OrderProcessed",
new Dictionary<string, string> { {"OrderId", order.Id} });
// 性能监控
using var operation = telemetryClient.StartOperation<DependencyTelemetry>("DatabaseQuery");
try
{
await ExecuteDatabaseQuery();
operation.Telemetry.Success = true;
}
catch (Exception ex)
{
operation.Telemetry.Success = false;
telemetryClient.TrackException(ex);
throw;
}
健康检查看板配置
性能优化与成本控制
缓存策略实现
// Redis缓存集成
builder.Services.AddStackExchangeRedisCache(options =>
{
options.Configuration = builder.Configuration.GetConnectionString("Redis");
options.InstanceName = "MyApp:";
});
// 响应缓存
[ResponseCache(Duration = 60, Location = ResponseCacheLocation.Any)]
public IActionResult GetProducts()
{
return Ok(_productService.GetAll());
}
// 分布式缓存使用
public async Task<Product> GetProductAsync(int id)
{
var cacheKey = $"product:{id}";
var product = await _cache.GetStringAsync(cacheKey);
if (product == null)
{
product = await _dbContext.Products.FindAsync(id);
await _cache.SetStringAsync(cacheKey,
JsonSerializer.Serialize(product),
new DistributedCacheEntryOptions
{
AbsoluteExpirationRelativeToNow = TimeSpan.FromMinutes(5)
});
}
return JsonSerializer.Deserialize<Product>(product);
}
安全合规性配置
