Getting Started

Create a request and send it!

import 'package:aws_request/aws_request.dart';

AwsRequest request = new AwsRequest('awsAccessKey', 'awsSecretKey', 'region');
request.send(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
target: your instance of that service plus the operation (Logs_XXXXXXXX.PutLogEvents)
signedHeaders: a list of headers aws requires in the signature.
   Default included signed headers are: (content-type, host, x-amz-date, x-amz-target)
   (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 aws query string, formatted like ('abc=123&def=456'). Must be url encoded

Supported HTTP methods are get, post, delete, patch, put.

Examples

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

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

void sendCloudWatchLog(String logString) async {
  AwsRequest request = new AwsRequest('awsAccessKey', 'awsSecretKey', 'region');
  String body = """  
            {"logEvents":
              [{
                "timestamp":${DateTime
      .now()
      .toUtc()
      .millisecondsSinceEpoch},
                "message":"$logString"
              }],
              "logGroupName":"ExampleLogGroupName",
              "logStreamName":"ExampleLogStreamName"
            }""";
  HttpClientResponse result = await request.send(
    AwsRequestType.POST,
    jsonBody: body,
    target: 'Logs_20140328.PutLogEvents',
    service: 'logs',
  );
}
