如何为 AWS V3 Dynamo 客户端设置超时 [英] How do I set a timeout for AWS V3 Dynamo Clients

问题描述

我已开始将新的 AWS 版本 3 sdk 用于我的一些服务.不幸的是，并不总是清楚如何使用模块化版本 3 代码中的一些功能，这些功能在版本 2 sdk 中可用.

I have started using the new AWS Version 3 sdk for some of my services. Unfortunately it is not always clear how to use some features in the modular version 3 code that are available in the Version 2 sdk.

要为非模块化 sdk 设置超时，您可以执行以下操作:

To set timeouts for the non-modular sdk, you can do the following:

AWS.config.update({
     httpOptions: {
        connectTimeout: 10000,
        timeout: 10000
    }
 });

但是，当我想使用版本 3 sdk 并使用 Dynamo 客户端时，我明确尝试不使用全局 AWS 对象.据我所知，DynamoDBClient 的配置输入不接受 httpOptions，这是通常设置超时的地方.

However, when I want to use the Version 3 sdk and use the Dynamo client, I am explicitly trying not to use the global AWS object. As far as I can tell the configuration input to DynamoDBClient does not accept httpOptions, which is where a timeout would normally get set.

import { DynamoDBClient } from "@aws-sdk/client-dynamodb";
const REGION = process.env.AWS_REGION;
const v3DynamoClient: DynamoDBClient = new DynamoDBClient({ region: REGION });

如何在 AWS V3 sdk 中为 DynamoDBClient 设置超时?

推荐答案

以下是设置 TLS v1.2 选项的示例，应该会有所帮助:

Here's an example of setting TLS v1.2 options that should help:

const https = require("https");
const {NodeHttpHandler} = require("@aws-sdk/node-http-handler");
const {DynamoDBClient} = require("@aws-sdk/client-dynamodb");
const client = new DynamoDBClient({
  region: "us-west-2",
  requestHandler: new NodeHttpHandler({
    httpsAgent: new https.Agent({secureProtocol: 'TLSv1_2_method'})
  })
});

您应该能够在选项中将 connectionTimeout 或 socketTimeout 设置为 NodeHttpHandler.

You should be able to set connectionTimeout or socketTimeout in the options to NodeHttpHandler.

另外，值得一读 SDK v3 开发者指南.
