Http response body has quote marks from Dart Aqueduct server

When a response is returned from an Aqueduct controller like this 

return Response.ok('hello');

the body of the response has quote marks around it:

"hello"

The same thing when I return a JSON string like this:

return Response.ok('{"token":"$token"}');

I get this:

"{\"token\":\"eyJhbG...soOFY8\"}"

which is messing up the JSON parsing on the client side.

Is there any way to not send the quote marks?

Solution

  • The default ContentType of the response is JSON already. If you want to send plane text then you need to set the content type to plain text.

    // import 'dart:io';

return Response.ok('hello')..contentType = ContentType.text;

    The response body will be 

    hello

    To send JSON, just send a Map rather than converting it to a string yourself:

    return Response.ok({'token':token});

    This will give a response body of 

    {"token":"eyJhbGc...vCxdE"}
