If you have feedback or have a use case that isn't covered feel free to open an issue.

Getting Started

Create a request and send it!

import 'package:aws_request/aws_request.dart';

main() {
  final AwsRequest request = new AwsRequest(
    awsAccessKey: 'awsAccessKey',
    awsSecretKey: 'awsSecretKey', 
    region: 'region',
  );
  request.send(type: AwsRequestType.post);
}

The following parameters can be provided to the send() function:

type: request type (GET, POST, PUT, etc)
service: aws service you are sending request to
signedHeaders: a list of headers aws requires in the signature.
   Default included signed headers are: (content-type, host, x-amz-date)
   (You do not need to provide these in [headers])
headers: any required headers. Any non-default headers included in the signedHeaders 
         must be added here.
jsonBody: the body of the request, formatted as json
queryPath: the aws query path
queryString: the url query string as a Map

Supported HTTP methods are GET, POST, DELETE, PATCH, PUT, HEAD.

Important Notes:

Android

in your app's android/app/src/main/AndroidManifest.xml

Examples

Example 1

Here's an example of using aws_request to send a CloudWatch PutLogEvent request:

import 'package:aws_request/aws_request.dart';
import 'package:http/http.dart';

Future<void> awsRequestFunction(String logString) async {
  final AwsRequest request = new AwsRequest(
    awsAccessKey: 'awsAccessKey',
    awsSecretKey: 'awsSecretKey',
    region: 'region',
  );
  final Response result = await request.send(
    type: AwsRequestType.post,
    jsonBody: "{'jsonKey': 'jsonValue'}",
    service: 'lambda',
    queryString: {'X-Amz-Expires': '10'},
    headers: {'X-Amz-Security-Token': 'XXXXXXXXXXXX'},
  );
  print(result.statusCode);
}

Example 2

There is also a static method if you find that more useful:

import 'package:aws_request/aws_request.dart';
import 'package:http/http.dart';

void awsRequestFunction(String logString) async {
  Response result = await AwsRequest.staticSend(
    awsAccessKey: 'awsAccessKey',
    awsSecretKey: 'awsSecretKey',
    region: 'region',
    type: AwsRequestType.post,
    jsonBody: "{'jsonKey': 'jsonValue'}",
    service: 'logs',
    queryString: {'X-Amz-Expires': '10'},
    headers: {'X-Amz-Security-Token': 'XXXXXXXXXXXX'},
  );
}
