Sends an HTTP GET request with the given headers to the given URL, which can be a Uri or a String, and returns a Future that completes to the body of the response as a String.
The Future will emit a ClientException if the response doesn't have a success status code.
This automatically initializes a new Client and closes that client once the request is complete. If you're planning on making multiple requests to the same server, you should use a single Client for all of those requests.
For more fine-grained control over the request and response, use Request instead.
