使用 Amazon Simple Notification Service 从云端发送通知
注意
本主题中的信息特定于基于.NET Framework 和 3.3 及更早 SDK for .NET 版本的项目。
AWS SDK for .NET 支持亚马逊简单通知服务 (Amazon SNS) Simple Notification Service,这是一项网络服务,使应用程序、最终用户和设备能够立即从云端发送通知。有关更多信息,请参阅 Amazon SNS
列出您的 Amazon SNS 话题
以下示例说明如何列出您的 Amazon SNS 主题、每个主题的订阅以及每个主题的属性。此示例使用默认值AmazonSimpleNotificationServiceClient。
// 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
以下代码示例显示如何将消息发送到 Amazon SNS 主题中。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
以下示例说明如何向电话号码发送 SMS 消息。该示例采用一个参数,即电话号码,该参数必须采用注释中描述的两种格式中的任何一种。
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);
}
}
}
}
