class FaradayMiddleware::EncodeJson

Request middleware that encodes the body as JSON.

Processes only requests with matching Content-type or those without a type. If a request doesn’t have a type but has a body, it sets the Content-type to JSON MIME-type.

Doesn’t try to encode bodies that already are in string form.

Constants

CONTENT_TYPE
MIME_TYPE
MIME_TYPE_REGEX
