Handle media type validation in HTTP requests.
This is an httpd callback module handling
media type validation of HTTP operations. The HTTP resources are
managed in modules named ocs_rest_res_*.
The resource handler modules should implement the following
callback functions.
content_types_provided() -> ContentTypes
- ContentTypes = [ContentType]
- ContentType = string()
Provides the list of possible media types in response bodies
provided by functions in the resource handler module.
content_types_accepted() -> ContentTypes
- ContentTypes = [ContentType]
- ContentType = string()
Provides the list of possible media types accepted in bodies
provided to functions in the resource handler module.
do(ModData) -> Result
- ModData = #mod{}
- Result = {proceed, OldData} | {proceed, NewData} | {break, NewData} | done
- OldData = list()
- NewData = [{response, {StatusCode, Body}}] | [{response, {response, Head, Body}}] | [{response, {already_sent, StatusCode, Size}}]
- StatusCode = integer()
- Body = iolist() | nobody | {Fun, Arg}
- Head = [HeaderOption]
- HeaderOption = {Option, Value} | {code, StatusCode}
- Option = accept_ranges | allow | cache_control | content_MD5 | content_encoding | content_language | content_length | content_location | content_range | content_type | date | etag | expires | last_modified | location | pragma | retry_after | server | trailer | transfer_encoding
- Value = string()
- Size = term()
- Fun = fun((Arg) -> sent | close | Body)
- Arg = [term()]
