The request signature we calculated does not match the signature you provided

[Rayv1]

Hi,

i have a Problem with the Encoding and i have no clue where its coming from.

Package: 2 0.1.12+3

What iam Doing:
Get request against API Gateway.

code:

    final signedRequest = new SigV4Request(
      awsSigV4Client,
      method: 'GET',
      path: "/path/$querystring",
      headers: new Map<String, String>.from({}),
      queryParams: new Map<String, String>.from({}),
    );
    Response response;
    response = await http.get(
      signedRequest.url,
      options: Options(
        headers: signedRequest.headers,
      ),
    );

When i pass no special Characters it works, but as soon i pass characters like &ÄÜÖ i receive an error:
"The request signature we calculated does not match the signature you provided
The Canonical String for this request should have been
'GET
/path/%25C3%25A4 (<<< is an double encoded 'ä')
"
it seems like it is double encoded and i have no clue where to start whats going on here.

Any thoughts?

Best Regards,

Hey,
I would recommend you to change umlauts with their analogs like ae, oe, ue.
If it isn't possible, pls check this topic dart-lang/http#227

First of all, check what the package pass to http to find if this package or http package is the reason.
