NAME¶

zhttp_request - Class for zhttp server request.

SYNOPSIS¶

//  This is a draft class, and may change without notice. It is disabled in
//  stable builds by default. If you use this in applications, please ask
//  for it to be pushed to stable state. Use --enable-drafts to enable.
#ifdef CZMQ_BUILD_DRAFT_API
//  *** Draft method, for development use, may change without warning ***
//  Create a new http request.
CZMQ_EXPORT zhttp_request_t *


    zhttp_request_new (void);
//  *** Draft method, for development use, may change without warning ***
//  Destroy an http request.

//  *** Draft method, for development use, may change without warning ***
//  Receive a new request from zhttp_server.
//  Return the underlying connection if successful, to be used when calling zhttp_response_send.
CZMQ_EXPORT void *


    zhttp_request_recv (zhttp_request_t *self, zsock_t *sock);
//  *** Draft method, for development use, may change without warning ***
//  Send a request to zhttp_client.
//  Url and the request path will be concatenated.
//  This behavior is useful for url rewrite and reverse proxy.
//
//  Send also allow two user provided arguments which will be returned with the response.
//  The reason for two, is to be able to pass around the server connection when forwarding requests or both a callback function and an arg.

//  *** Draft method, for development use, may change without warning ***
//  Get the request method

//  *** Draft method, for development use, may change without warning ***
//  Get the request url.
//  When receiving a request from http server this is only the path part of the url.

//  *** Draft method, for development use, may change without warning ***
//  Set the request url
//  When sending a request to http client this should be full url.

//  *** Draft method, for development use, may change without warning ***
//  Get the content of the request.
CZMQ_EXPORT const char *


    zhttp_request_content (zhttp_request_t *self);
//  *** Draft method, for development use, may change without warning ***
//  Get the content of the request.
//  Caller owns return value and must destroy it when done.
CZMQ_EXPORT char *

//  *** Draft method, for development use, may change without warning ***
//  Set the content of the request.

//  *** Draft method, for development use, may change without warning ***
//  Set the content of the request..
//  The content is assumed to be constant-memory and will therefore not be copied or deallocated in any way.
CZMQ_EXPORT void

//  *** Draft method, for development use, may change without warning ***
//  Match the path of the request.
//  Support wildcards with '%s' symbol inside the match string.
//  Matching wildcards until the next '/', '?' or '\0'.
//  On successful match the variadic arguments will be filled with the matching strings.
//  On successful match the method is modifying the url field and break it into substrings.
//  If you need to use the url, do it before matching or take a copy.
//
//  User must not free the variadic arguments as they are part of the url.
//
//  To use the percent symbol, just double it, e.g "%%something".
//
//  Example:
//  if (zhttp_request_match (request, "POST", "/send/%s/%s", &name, &id))
