method options : ((string * string) list, 'body) op
If the `OPTIONS
method is supported by this resource, the returned list of header name/value pairs will be included in responses to `OPTIONS
requests.
Default: [("allow", self#allowed_methods)]
method known_methods : (Cohttp.Code.meth list, 'body) op
A request to this resource whose method is not included in the returned list will result in a 501 Not Implemented
.
Default: [`GET; `HEAD; `POST; `PUT; `DELETE; `Other "TRACE"; `Other "CONNECT"; `OPTIONS]
method allowed_methods : (Cohttp.Code.meth list, 'body) op
A request to this resource whose method is not included in the returned list will result in a 405 Method Not Allowed
. The response will include an "allow"
header that lists the allowed methods.
Default: [`GET; `HEAD]
method delete_resource : (bool, 'body) op
`DELETE
requests will call this method. Returning true
indicates that the deletion succeeded.
Default: false
method delete_completed : (bool, 'body) op
Only successful delete_resource calls will result in a call to this method. Return false
if the deletion was accepted but cannot yet be guaranteed to have finished.
Default: true
method process_post : (bool, 'body) op
`POST
requests will call this method. Returning true indicates the POST succeeded.
method process_property : (property_response, 'body) op
method cannot_create : (unit, 'body) op
method create_collection : (collection_created_response, 'body) op
method report : (report_response, 'body) op

Default: true
method charsets_provided : ((string * ('body -> 'body)) list, 'body) op
method encodings_provided : ((string * ('body -> 'body)) list, 'body) op
method variances : (string list, 'body) op
Returns a list of header names that should be included in the response's Vary
header. The standard content negotiation headers (i.e., Accept
, Accept-Encoding
, Accept-Charset
, Accept-Language
) will automatically be added if needed, and therefore do not need to be specified here.
Default: []
method is_conflict : (bool, 'body) op
Returning true
will result in a 409 Conflict
.
Default: false
method multiple_choices : (bool, 'body) op
Returning true
indicates that multiple representations of the resource exist and a single one cannot be automatically chosen, resulting in a 300 Multiple Choices
rather than a 200 OK
.
Default: false
method previously_existed : (bool, 'body) op
method moved_permanently : (Uri.t option, 'body) op
method moved_temporarily : (Uri.t option, 'body) op
method last_modified : (string option, 'body) op
method expires : (string option, 'body) op
method generate_etag : (string option, 'body) op
Returning Some string
will use string
for the ETag
header.
Default: None
method finish_request : (unit, 'body) op
This method is called just before the final response is constructed and returned.
method post_is_create : (bool, 'body) op
If POST requests should be treated as a request to put content into a (potentially new) resource as opposed to being a generic submission for processing, then this function should return true. If it does return true, then create_path will be called and the rest of the request will be treated much like a PUT to the Path entry returned by that call.
Default: false
method create_path : (string, 'body) op
This will be called on a POST request if post_is_create returns true. It is an error for this function not to produce a Path if post_is_create returns true. The Path returned should be a valid URI part following the dispatcher prefix. That Path will replace the previous one in the return value of wrq:disp_path(ReqData) for all subsequent resource function calls in the course of this request.
method allow_missing_post : (bool, 'body) op
If the resource accepts POST requests to nonexistent resources, then this should return true.
Default : false
