没有等待的QqsClient.SendMessageAsync不起作用 [英] QqsClient.SendMessageAsync without await doesn't work

问题描述

我有一个Lambda函数，该lambda函数应该将消息发送到SQS中的多个队列，然后退出，

I have a Lambda function and that lambda function is supposed to send messages to multiple queues in SQS and then exit,

如果我添加一个等待，则消息将发送到所有队列，

If I add await, then messages are sent to all queues,

var sqsClient = ServerlessHelper.GetAmazonSqsClient();
foreach (var item in items)
{
    await sqsClient.SendMessageAsync(item.QueueUrl, item.Message);
}

但是，如果我从代码中删除了await，则不会有任何消息发送到队列.我想并行发送消息.但是由于等待，我有功能无法并行发送消息.我正在尝试做这样的事情，

But if I remove await from the code, then none of messages are sent to queues. I want to send messages in parallel. But due to await I have function cannot send messages in parallel. I am trying to do something like this,

var sqsClient = ServerlessHelper.GetAmazonSqsClient();
foreach (var item in items)
{
    sqsClient.SendMessageAsync(item.QueueUrl, item.Message);
}
// wait until are messages are sent to queues.

有可能这样做吗?

推荐答案

我正在猜测 sqsClient.SendMessageAsync(item.QueueUrl，item.Message); 返回一个Task，因为它是一个异步函数?

I'm guessing sqsClient.SendMessageAsync(item.QueueUrl, item.Message); returns a Task since it is an async function?

您需要保存任务实例，然后使用 Task.WhenAll ，如该示例

You need to save the task instances then use Task.WhenAll as in this example.
