Amazon SNS 訊息發布

AWS Management Console AWS 開發套件

在您 create an Amazon SNS topic (建立 Amazon SNS 主題) 並讓端點 subscribe (訂閱) 主題之後，您可以將訊息 publish (發布) 至主題。發布訊息時，Amazon SNS 會嘗試將訊息傳送到已訂閱的端點。

主題

登入 Amazon SNS 主控台。
在左側導覽窗格中，選擇 Topics (主題)。
在 Topics (主題) 頁面上，選取主題然後選擇 Publish message (發布訊息)。

主控台會開啟 Publish message to topic (將訊息發布至主題) 頁面。
在 Message details(訊息詳細資訊) 區段中，執行下列動作：
1. (選用) 輸入訊息 Subject (主旨)。
2. 對於 FIFO topic (FIFO 主題)，輸入 Message group ID (訊息群組 ID)。相同訊息群組中的訊息會依發布順序傳遞。
3. 對於 FIFO 主題，請輸入 Message deduplication ID (訊息重複資料刪除 ID)。如果您啟用內容為基礎的訊息重複資料刪除的主題設定，此 ID 是選擇性的。
4. (選用) 針對 mobile push notifications (行動推播通知)，輸入 Time to Live (TTL) (存留時間 (TTL)) 值 (以秒為單位)。這是推播通知服務 (例如 Apple 推播通知服務 (APN) 或 Firebase 雲端訊息 (FCM)) 傳送訊息到端點所需的時間量。
在 Message body (訊息內文) 區段中，執行下列任一動作：
1. 選擇 Identical payload for all delivery protocols (所有傳送協定的相同酬載) 然後輸入訊息。
2. 選擇 Custom payload for each delivery protocol (各傳送協定自訂酬載)，然後使用 JSON 物件定義傳送至各協定的訊息。
  
  如需詳細資訊，請參閱使用平台特定承載進行發佈。
在 Message attributes (訊息屬性) 區段中，新增您要讓 Amazon SNS 與 FilterPolicy 訂閱屬性比對的任何屬性，用以判斷訂閱的端點是否對發布的訊息感興趣。
1. 針對 Type (類型)，選擇屬性類型，例如 String.Array。
  
  注意
  針對屬性類型 String.Array，將陣列放在方括號 ([]) 中。在陣列內，以雙引號括住字串值。您不需要對數字或關鍵字 true、false 以及 null 使用引號。
2. 輸入屬性名稱，例如 customer_interests。
3. 輸入屬性數值，例如 ["soccer", "rugby", "hockey"]。
如果屬性類型為 String (字串)、String.Array，或 Number (數字)，且篩選政策範圍未明確設為 MessageBody，Amazon SNS 會以訂閱的篩選政策 (如果在傳送訊息到該訂閱之前出現) 來評估訊息屬性。

如需詳細資訊，請參閱 Amazon SNS 訊息屬性。
選擇 Publish message (發佈訊息)。

訊息會發布到主題，主控台會開啟主題的 Details (詳細資訊) 頁面。

使用 AWS SDK 將訊息發布至主題

要使用 AWS SDK，您必須使用憑據對其進行配置。如需詳細資訊，請參閱 AWS SDK和工具參考指南中的共享的配置和認證文件。

下列程式碼範例會示範如何使用Publish。

下列 publish 範例會將指定的訊息發佈到指定的 SNS 主題。訊息來自文字檔案，可讓您包含換行符號。


aws sns publish \
    --topic-arn "arn:aws:sns:us-west-2:123456789012:my-topic" \
    --message file://message.txt

message.txt 的內容：


Hello World
Second Line

輸出：


{
    "MessageId": "123a45b6-7890-12c3-45d6-111122223333"
}

範例 2：將簡訊發布至電話號碼

下列 publish 範例會將訊息 Hello world! 發佈至電話號碼 +1-555-555-0100。


aws sns publish \
    --message "Hello world!" \
    --phone-number +1-555-555-0100

輸出：

PowerShell

適用的工具 PowerShell

範例 1：此範例顯示以單一 MessageAttribute 宣告的內嵌方式發佈郵件。


Publish-SNSMessage -TopicArn "arn:aws:sns:us-west-2:123456789012:my-topic" -Message "Hello" -MessageAttribute @{'City'=[Amazon.SimpleNotificationService.Model.MessageAttributeValue]@{DataType='String'; StringValue ='AnyCity'}}

示例 2：此示例顯示發布具有多個事先 MessageAttributes 聲明的消息。


$cityAttributeValue = New-Object Amazon.SimpleNotificationService.Model.MessageAttributeValue
$cityAttributeValue.DataType = "String"
$cityAttributeValue.StringValue = "AnyCity"

$populationAttributeValue = New-Object Amazon.SimpleNotificationService.Model.MessageAttributeValue
$populationAttributeValue.DataType = "Number"
$populationAttributeValue.StringValue = "1250800"

$messageAttributes = New-Object System.Collections.Hashtable
$messageAttributes.Add("City", $cityAttributeValue)
$messageAttributes.Add("Population", $populationAttributeValue)

Publish-SNSMessage -TopicArn "arn:aws:sns:us-west-2:123456789012:my-topic" -Message "Hello" -MessageAttribute $messageAttributes
