const char *  url,
const char *  method,
const char *  version,
const char *  upload_data,
size_t *  upload_data_size,
void **  con_cls 
)
static

Main request handler.

Parameters
clsargument given together with the function pointer when the handler was registered with MHD
connection
urlthe requested url
methodthe HTTP method used (#MHD_HTTP_METHOD_GET, #MHD_HTTP_METHOD_PUT, etc.)
versionthe HTTP version string (i.e. #MHD_HTTP_VERSION_1_1)
upload_datathe data being uploaded (excluding HEADERS, for a POST that fits into memory and that is encoded with a supported encoding, the POST data will NOT be given in upload_data and is instead available as part of #MHD_get_connection_values; very large POST data will be made available incrementally in upload_data)
upload_data_sizeset initially to the size of the upload_data provided; the method must update this value to the number of bytes NOT processed;
con_clspointer that the callback can set to some address and that will be preserved by MHD for future calls for this request; since the access handler may be called many times (i.e., for a PUT/POST operation with plenty of upload data) this allows the application to easily associate some request-specific state. If necessary, this state can be cleaned up in the global #MHD_RequestCompletedCallback (which can be set with the #MHD_OPTION_NOTIFY_COMPLETED). Initially, *con_cls will be NULL.
Returns
#MHD_YES if the connection was handled successfully, #MHD_NO if the socket must be closed due to a serios error while handling the request
