EventBridge 使用 Amazon SDK 的代码示例
以下代码示例说明如何 EventBridge 使用 Amazon 软件开发套件 (SDK)。
操作是大型程序的代码摘录，必须在上下文中运行。您可以通过操作了解如何调用单个服务函数，还可以通过函数相关场景和跨服务示例的上下文查看操作。
场景 是展示如何通过在同一服务中调用多个函数来完成特定任务的代码示例。
跨服务示例是指跨多个 Amazon Web Services工作的示例应用程序。
有关 S Amazon DK 开发者指南和代码示例的完整列表，请参阅 EventBridge 与 Amazon SDK 一起使用。本主题还包括有关入门的信息以及有关先前的 SDK 版本的详细信息。
开始使用
以下代码示例显示了如何开始使用 EventBridge。
- .NET

- Amazon SDK for .NET
-
using Amazon.EventBridge;
using Amazon.EventBridge.Model;
namespace EventBridgeActions;
public static class HelloEventBridge
{
static async Task Main(string[] args)
{
var eventBridgeClient = new AmazonEventBridgeClient();
Console.WriteLine($"Hello Amazon EventBridge! Following are some of your EventBuses:");
Console.WriteLine();
// You can use await and any of the async methods to get a response.
// Let's get the first five event buses.
var response = await eventBridgeClient.ListEventBusesAsync(
new ListEventBusesRequest()
{
Limit = 5
});
foreach (var eventBus in response.EventBuses)
{
Console.WriteLine($"\tEventBus: {eventBus.Name}");
Console.WriteLine($"\tArn: {eventBus.Arn}");
Console.WriteLine($"\tPolicy: {eventBus.Policy}");
Console.WriteLine();
}
}
}
