PostToConnection 搭配 AWS SDK 或 CLI 使用

將資料傳送至 WebSocket 連線

下列post-to-connection範例會傳送訊息至連線至指定 WebSocket API 的用戶端。

aws apigatewaymanagementapi post-to-connection \
    --connection-id L0SM9cOFvHcCIhw= \
    --data "Hello from API Gateway!" \
    --endpoint-url https://aabbccddee.execute-api.us-west-2.amazonaws.com/prod

此命令不會產生輸出。

如需詳細資訊，請參閱《Amazon API Gateway 開發人員指南》中的在後端服務中使用 @connections 命令。

async fn send_data(
    client: &aws_sdk_apigatewaymanagement::Client,
    con_id: &str,
    data: &str,
) -> Result<(), aws_sdk_apigatewaymanagement::Error> {
    client
        .post_to_connection()
        .connection_id(con_id)
        .data(Blob::new(data))
        .send()
        .await?;

    Ok(())
}

    let endpoint_url = format!(
        "https://{api_id}.execute-api.{region}.amazonaws.com/{stage}",
        api_id = api_id,
        region = region,
        stage = stage
    );

    let shared_config = aws_config::from_env().region(region_provider).load().await;
    let api_management_config = config::Builder::from(&shared_config)
        .endpoint_url(endpoint_url)
        .build();
    let client = Client::from_conf(api_management_config);
