See * the section "The Old SoupServer * Listening API" in the server how-to documentation for * details on the older #SoupServer API.) * * To begin, create a server using soup_server_new(). Add at least one * handler by calling soup_server_add_handler() or * soup_server_add_early_handler(); the handler will be called to * process any requests underneath the path you pass. (If you want all * requests to go to the same handler, just pass "/" (or %NULL) for * the path.) * * When a new connection is accepted (or a new request is started on * an existing persistent connection), the #SoupServer will emit * #SoupServer::request-started and then begin processing the request * as described below, but note that once the message is assigned a * #SoupMessage:status-code, then callbacks after that point will be * skipped. Note also that it is not defined when the callbacks happen * relative to various #SoupMessage signals. * * Once the headers have been read, #SoupServer will check if there is * a #SoupAuthDomain (qv) covering the Request-URI; if so, and if the * message does not contain suitable authorization, then the * #SoupAuthDomain will set a status of %SOUP_STATUS_UNAUTHORIZED on * the message. * * After checking for authorization, #SoupServer will look for "early" * handlers (added with soup_server_add_early_handler()) matching the * Request-URI. If one is found, it will be run; in particular, this * can be used to connect to signals to do a streaming read of the * request body. * * (At this point, if the request headers contain "Expect: * 100-continue", and a status code has been set, then * #SoupServer will skip the remaining steps and return the response. * If the request headers contain "Expect: * 100-continue" and no status code has been set, * #SoupServer will return a %SOUP_STATUS_CONTINUE status before * continuing.) * * The server will then read in the response body (if present). At * this point, if there are no handlers at all defined for the * Request-URI, then the server will return %SOUP_STATUS_NOT_FOUND to * the client. * * Otherwise (assuming no previous step assigned a status to the * message) any "normal" handlers (added with * soup_server_add_handler()) for the message's Request-URI will be * run. * * Then, if the path has a WebSocket handler registered (and has * not yet been assigned a status), #SoupServer will attempt to * validate the WebSocket handshake, filling in the response and * setting a status of %SOUP_STATUS_SWITCHING_PROTOCOLS or * %SOUP_STATUS_BAD_REQUEST accordingly. * * If the message still has no status code at this point (and has not * been paused with soup_server_pause_message()), then it will be * given a status of %SOUP_STATUS_INTERNAL_SERVER_ERROR (because at * least one handler ran, but returned without assigning a status). * * Finally, the server will emit #SoupServer::request-finished (or * #SoupServer::request-aborted if an I/O error occurred before * handling was completed). * * If you want to handle the special "*" URI (eg, "OPTIONS *"), you * must explicitly register a handler for "*"; the default handler * will not be used for that case. * * If you want to process https connections in addition to (or instead * of) http connections, you can either set the * SoupServer:tls-certificate property when creating the server, or * else call soup_server_set_ssl_cert_file() after creating it. * * Once the server is set up, make one or more calls to * soup_server_listen(), soup_server_listen_local(), or * soup_server_listen_all() to tell it where to listen for * connections. (All ports on a #SoupServer use the same handlers; if * you need to handle some ports differently, such as returning * different data for http and https, you'll need to create multiple * #SoupServers, or else check the passed-in URI in the handler * function.). * * #SoupServer will begin processing connections as soon as you return * to (or start) the main loop for the current thread-default * #GMainContext. */ /** * SoupServer: * * Class implementing an HTTP server. */ enum { REQUEST_STARTED, REQUEST_READ, REQUEST_FINISHED, REQUEST_ABORTED, LAST_SIGNAL };
