AWS SQS 的 JavaScript 使用方式

方法1： 

import {Injectable} from '@nestjs/common';
import {SQS} from 'aws-sdk';

@Injectable()
export class SqsService {
  private client: SQS;
  private awsAccessKey = process.env.AWS_ACCESS_KEY_ID;
  private awsSecretKey = process.env.AWS_SECRET_ACCESS_KEY;
  private awsRegion = process.env.AWS_REGION;

  constructor() {
    this.client = new SQS({
      credentials: {
        accessKeyId: this.awsAccessKey,
        secretAccessKey: this.awsSecretKey,
      },
      region: this.awsRegion,
      sslEnabled: true,
    });

    /**
     * The code below is used for testing if the SQS service works.
    */
    this.client.listQueues({}, (err, data) => {
      if (err) console.log(err, err.stack); // an error occurred
      else console.log(data); // successful response
    });
  }
}

方法2：

import {Injectable} from '@nestjs/common';
import {AWSError, SQS} from 'aws-sdk';
const AWS = require('aws-sdk');

@Injectable()
export class SqsService {
  private client: SQS;
  private awsAccessKey = process.env.AWS_ACCESS_KEY_ID;
  private awsSecretKey = process.env.AWS_SECRET_ACCESS_KEY;
  private awsRegion = process.env.AWS_REGION;

  constructor() {
    this.client = new AWS.SQS({
      credentials: {
        accessKeyId: this.awsAccessKey,
        secretAccessKey: this.awsSecretKey,
      },
      region: this.awsRegion,
      sslEnabled: true,
    });

    /**
     * The code below is used for testing if the SQS service works.
    */
    this.client.listQueues({}, (err, data) => {
      if (err) console.log(err, err.stack); // an error occurred
      else console.log(data); // successful response
    });
  }
}

以上两种方法都是正确的。

以下报错产生于 this.client.sendMessage() ，但是报错信息中确有 InvalidClientTokenId: The security token included in the request is invalid. 的字样，sendMessage 代码与官方文档一致，令人困惑。

    this.client.sendMessage(sendMessageRequest, (err, data) => {
      if (err) console.log(err); // an error occurred
      else console.log(data); // successful response}
    });

原因是队列的 URL 写错了！
