从NodeJS向Amazon Lex发出POST请求

const axios = require('axios');

const lexBotUrl = 'https://runtime.lex.us-east-1.amazonaws.com/bot/myBot/alias/$LATEST/user/userId/text';
const accessKeyId = 'YOUR_ACCESS_KEY_ID';
const secretAccessKey = 'YOUR_SECRET_ACCESS_KEY';

const userInput = 'Hello, how are you?';

axios.post(lexBotUrl, {
  inputText: userInput
}, {
  headers: {
    'Content-Type': 'application/json',
    'Authorization': `AWS4-HMAC-SHA256 Credential=${accessKeyId}/20220101/us-east-1/lex/aws4_request, SignedHeaders=content-type;host;x-amz-date, Signature=YOUR_SIGNATURE`
  }
})
  .then(response => {
    console.log(response.data);
    // 处理返回的响应数据
  })
  .catch(error => {
    console.error(error);
    // 处理请求错误
  });
