 Returns an array of NSURLQueryItems constructed from the request parameters. The query items in the array are not
 URL encoded.

 Supported value types of the dictionary are String or Array. Any other type of value will throw an
 NSInternalInconsistencyException. If the value is an array, each value will be added to the resulting array using the
 key, for example: `{"key1", ["value1", "value2"]}` would result in an array `[("key1", "value1"), ("key1", "value2")]`.
