Difficulty making AWS GetLogEvents API call in a Node application

Vote count: 0

I can't use the Node aws-sdk because it depends on the http library which is not available to me in React Native.

I'm trying to use axios and react-native-aws-signature to craft a request to this AWS API endpoint: http://ift.tt/2lvcxeV

I'm getting a 403: Missing Authentication Token from AWS.

Here's my attempt:

var axios = require('axios');
var AWSSignature = require('react-native-aws-signature');

var awsSignature = new AWSSignature();
var date = awsSignature.formatDateTime(new Date(Date.now()).toISOString());

var body = JSON.stringify({
  logGroupName: 'xxx',
  logStreamName: 'production',
  limit: 30,
  startFromHead: false
}, null, 0);

var host = `logs.ap-southeast-2.amazonaws.com`;

var headers = {
  Host: host,
  'X-Amz-Date': date,
  'region': 'ap-southeast-2',
  Connection: 'Keep-Alive',
  'Content-Length': body.length,
  Accept: 'application/json',
  'Content-Type': 'application/x-amz-json-1.1',
  'X-Amz-Target': 'Logs_20140328.GetLogEvents',
};

var options = {
  path: '/',
  method: 'post',
  service: 'logs',
  headers,
  region: 'ap-southeast-2',
  body,
  credentials: {
    SecretKey: 'xxx',
    AccessKeyId: 'xxx'
  }
};

awsSignature.setParams(options);
var authorization = awsSignature.getAuthorizationHeader();

var headersWithAuth = headers;
headersWithAuth['Authorization'] = authorization;

axios.post(`https://${host}/`, body, headersWithAuth).then(response => {
  console.log(response.data);
}).catch(err => {
  console.log(err);
});

Been experimenting all night -- very frustrating. Thanks for any help.
