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
