使用 Amazon 简单通知服务从云发送通知

注意

本主题中的信息特定于基于 .NET 框架和Amazon SDK for .NET版本 3.3 及更早版本。

这些区域有:Amazon SDK for .NET支持 Amazon Simple Notification Service (Amazon SNS),这是一项 Web 服务,应用程序、最终用户和设备可以通过云即时发送通知。有关更多信息,请参阅 Amazon SNS

列出您的 Amazon SNS 主题

以下示例显示了如何列出您的 Amazon SNS 主题、每个主题的订阅以及每个主题的属性。本示例使用默认值AmazonSimpleNotificationServiceClient,它从默认配置中加载凭据。

// using Amazon.SimpleNotificationService; // using Amazon.SimpleNotificationService.Model; var client = new AmazonSimpleNotificationServiceClient(); var request = new ListTopicsRequest(); var response = new ListTopicsResponse(); do { response = client.ListTopics(request); foreach (var topic in response.Topics) { Console.WriteLine("Topic: {0}", topic.TopicArn); var subs = client.ListSubscriptionsByTopic( new ListSubscriptionsByTopicRequest { TopicArn = topic.TopicArn }); var ss = subs.Subscriptions; if (ss.Any()) { Console.WriteLine(" Subscriptions:"); foreach (var sub in ss) { Console.WriteLine(" {0}", sub.SubscriptionArn); } } var attrs = client.GetTopicAttributes( new GetTopicAttributesRequest { TopicArn = topic.TopicArn }).Attributes; if (attrs.Any()) { Console.WriteLine(" Attributes:"); foreach (var attr in attrs) { Console.WriteLine(" {0} = {1}", attr.Key, attr.Value); } } Console.WriteLine(); } request.NextToken = response.NextToken; } while (!string.IsNullOrEmpty(response.NextToken));

将消息发送到 Amazon SNS 主题

以下示例显示了如何将消息发送到 Amazon SNS 主题。该示例采用了一个参数,即 Amazon SNS 主题的 ARN。

using System; using System.Linq; using System.Threading.Tasks; using Amazon; using Amazon.SimpleNotificationService; using Amazon.SimpleNotificationService.Model; namespace SnsSendMessage { class Program { static void Main(string[] args) { /* Topic ARNs must be in the correct format: * arn:aws:sns:REGION:ACCOUNT_ID:NAME * * where: * REGION is the region in which the topic is created, such as us-west-2 * ACCOUNT_ID is your (typically) 12-character account ID * NAME is the name of the topic */ string topicArn = args[0]; string message = "Hello at " + DateTime.Now.ToShortTimeString(); var client = new AmazonSimpleNotificationServiceClient(region: Amazon.RegionEndpoint.USWest2); var request = new PublishRequest { Message = message, TopicArn = topicArn }; try { var response = client.Publish(request); Console.WriteLine("Message sent to topic:"); Console.WriteLine(message); } catch (Exception ex) { Console.WriteLine("Caught exception publishing request:"); Console.WriteLine(ex.Message); } } } }

向一个电话号码发送 SMS 消息

以下示例显示如何将 SMS 消息发送到电话号码。该示例采用一个参数,即电话号码,该参数必须采用评论中描述的两种格式之一。

using System; using System.Linq; using System.Threading.Tasks; using Amazon; using Amazon.SimpleNotificationService; using Amazon.SimpleNotificationService.Model; namespace SnsPublish { class Program { static void Main(string[] args) { // US phone numbers must be in the correct format: // +1 (nnn) nnn-nnnn OR +1nnnnnnnnnn string number = args[0]; string message = "Hello at " + DateTime.Now.ToShortTimeString(); var client = new AmazonSimpleNotificationServiceClient(region: Amazon.RegionEndpoint.USWest2); var request = new PublishRequest { Message = message, PhoneNumber = number }; try { var response = client.Publish(request); Console.WriteLine("Message sent to " + number + ":"); Console.WriteLine(message); } catch (Exception ex) { Console.WriteLine("Caught exception publishing request:"); Console.WriteLine(ex.Message); } } } }
