It parses both requests and +responses. The parser is designed to be used in performance HTTP +applications. It does not make any syscalls nor allocations, it does not +buffer data, it can be interrupted at anytime. Depending on your +architecture, it only requires about 40 bytes of data per message +stream (in a web server that is per connection). + +Features: + + * No dependencies + * Handles persistent streams (keep-alive). + * Decodes chunked encoding. + * Upgrade support + * Defends against buffer overflow attacks. + +The parser extracts the following information from HTTP messages: + + * Header fields and values + * Content-Length + * Request method + * Response status code + * Transfer-Encoding + * HTTP version + * Request URL + * Message body + + +Usage +----- + +One `http_parser` object is used per TCP connection. Initialize the struct +using `http_parser_init()` and set the callbacks. That might look something +like this for a request parser: + + http_parser_settings settings; + settings.on_url = my_url_callback; + settings.on_header_field = my_header_field_callback; + /* ... */ + + http_parser *parser = malloc(sizeof(http_parser)); + http_parser_init(parser, HTTP_REQUEST); + parser->data = my_socket; + +When data is received on the socket execute the parser and check for errors. + + size_t len = 80*1024, nparsed; + char buf[len]; + ssize_t recved; + + recved = recv(fd, buf, len, 0); + + if (recved < 0) { + /* Handle error. */ + } + + /* Start up / continue the parser. + * Note we pass recved==0 to signal that EOF has been recieved. + */ + nparsed = http_parser_execute(parser, &settings, buf, recved); + + if (parser->upgrade) { + /* handle new protocol */ + } else if (nparsed != recved) { + /* Handle error. Usually just close the connection. */ + } + +HTTP needs to know where the end of the stream is. For example, sometimes +servers send responses without Content-Length and expect the client to +consume input (for the body) until EOF. To tell http_parser about EOF, give +`0` as the forth parameter to `http_parser_execute()`. Callbacks and errors +can still be encountered during an EOF, so one must still be prepared +to receive them. + +Scalar valued message information such as `status_code`, `method`, and the +HTTP version are stored in the parser structure. This data is only +temporally stored in `http_parser` and gets reset on each new message. If +this information is needed later, copy it out of the structure during the +`headers_complete` callback. + +The parser decodes the transfer-encoding for both requests and responses +transparently. That is, a chunked encoding is decoded before being sent to +the on_body callback. + + +The Special Problem of Upgrade +------------------------------ + +HTTP supports upgrading the connection to a different protocol. An +increasingly common example of this is the Web Socket protocol which sends +a request like + + GET /demo HTTP/1.1 + Upgrade: WebSocket + Connection: Upgrade + Host: example.com + Origin: http://example.com + WebSocket-Protocol: sample + +followed by non-HTTP data. + +(See http://tools.ietf.org/html/draft-hixie-thewebsocketprotocol-75 for more +information the Web Socket protocol.) + +To support this, the parser will treat this as a normal HTTP message without a +body. Issuing both on_headers_complete and on_message_complete callbacks. However +http_parser_execute() will stop parsing at the end of the headers and return. + +The user is expected to check if `parser->upgrade` has been set to 1 after +`http_parser_execute()` returns. Non-HTTP data begins at the buffer supplied +offset by the return value of `http_parser_execute()`. + + +Callbacks +--------- + +During the `http_parser_execute()` call, the callbacks set in +`http_parser_settings` will be executed. The parser maintains state and +never looks behind, so buffering the data is not necessary. If you need to +save certain data for later usage, you can do that from the callbacks. + +There are two types of callbacks: + +* notification `typedef int (*http_cb) (http_parser*);` + Callbacks: on_message_begin, on_headers_complete, on_message_complete. +* data `typedef int (*http_data_cb) (http_parser*, const char *at, size_t length);` + Callbacks: (requests only) on_uri, + (common) on_header_field, on_header_value, on_body; + +Callbacks must return 0 on success. Returning a non-zero value indicates +error to the parser, making it exit immediately. + +In case you parse HTTP message in chunks (i.e. `read()` request line +from socket, parse, read half headers, parse, etc) your data callbacks +may be called more than once. Http-parser guarantees that data pointer is only +valid for the lifetime of callback. You can also `read()` into a heap allocated +buffer to avoid copying memory around if this fits your application. + +Reading headers may be a tricky task if you read/parse headers partially. +Basically, you need to remember whether last header callback was field or value +and apply following logic: + + (on_header_field and on_header_value shortened to on_h_*) + ------------------------ ------------ -------------------------------------------- + | State (prev. callback) | Callback | Description/action | + ------------------------ ------------ -------------------------------------------- + | nothing (first call) | on_h_field | Allocate new buffer and copy callback data | + | | | into it | + ------------------------ ------------ -------------------------------------------- + | value | on_h_field | New header started. | + | | | Copy current name,value buffers to headers | + | | | list and allocate new buffer for new name | + ------------------------ ------------ -------------------------------------------- + | field | on_h_field | Previous name continues.

This + * kind of programming may take some getting used to. + * + * %QHttpServer is backed by Ryan + * Dahl's secure and fast http parser which makes it streaming + * till the lowest level. + * + * \section usage Usage + * + * Using %QHttpServer is very simple. Simply create a QHttpServer, + * connect a slot to the newRequest() signal and use the request and + * response objects. + * See the QHttpServer class documentation for an example. + * + * \example helloworld/helloworld.cpp + * \example helloworld/helloworld.h + * \example greeting/greeting.cpp + * \example greeting/greeting.h + * \example bodydata/bodydata.cpp + * \example bodydata/bodydata.h + */ + +/*! \class QHttpServer + * The QHttpServer class forms the basis of the %QHttpServer + * project. It is a fast, non-blocking HTTP server. + * + * These are the steps to create a server and respond to requests. + * + *
    + *
  1. Create an instance of QHttpServer.
    2. + *
  2. Connect a slot to the newRequest(QHttpRequest*, QHttpResponse*) + * signal.
    3. + *
  3. Create a QCoreApplication to drive the server event loop.
    4. + *
  4. Respond to clients by writing out to the QHttpResponse object.

The + * object itself can be deleted by connecting to QHttpResponse's done() + * slot as explained below. + * + * You should NOT delete the QHttpRequest object until it + * has emitted an QHttpRequest::end() signal. + * + * QHttpResponse queues itself up for auto-deletion once the application + * calls its end() method. Once the data has been flushed to the underlying + * socket, the object will emit a QHttpResponse::done() signal before queueing itself up + * for deletion. You should NOT interact with the response + * object once it has emitted QHttpResponse::done() although actual deletion does not + * happen until QHttpResponse::destroyed() is emitted. + * QHttpResponse::done() serves as a useful way to handle memory management of the + * application itself. For example: + * + * \code + * MyApp::MyApp() + * : QObject(0) + * { + * QHttpServer *s = new QHttpServer; + * connect(s, SIGNAL(newRequest(...)), this, SLOT(handle(...))); + * s.listen(8000); + * } + * + * void MyApp::handle(QHttpRequest *request, QHttpResponse *response) + * { + * if( request->url() matches a route ) + * new Responder(request, response); + * else + * new PageNotFound(request, response); + * } + * + * ... + * + * Responder::Responder(QHttpRequest *request, QHttpResponse *response) + * { + * m_request = request; + * + * connect(request, SIGNAL(end()), response, SLOT(end())); + * // Once the request is complete, the response is ended. + * // when the response ends, it deletes itself + * // the Responder object connects to done() + * // which will lead to it being deleted + * // and this will delete the request. + * // So all 3 are properly deleted. + * connect(response, SIGNAL(done()), this, SLOT(deleteLater())); + * response->writeHead(200); + * response->write("Quitting soon"); + * } + * + * Responder::~Responder() + * { + * delete m_request; + * m_request = 0; + * } + * \endcode + * + */ + void newRequest(QHttpRequest *request, QHttpResponse *response); + +private Q_SLOTS: + void newConnection(); + +private: + QTcpServer *m_tcpServer; +}; + +#endif diff --git a/src/http/qjson/CMakeLists.txt b/src/http/qjson/CMakeLists.txt new file mode 100644 index 000000000..e51a62fd7 --- /dev/null +++ b/src/http/qjson/CMakeLists.txt @@ -0,0 +1,28 @@ +# add_custom_command (OUTPUT ${qjson_SOURCE_DIR}/lib/json_parser.cc +# PRE_BUILD +# COMMAND bison -t -o json_parser.cc -d json_parser.yy +# DEPENDS json_parser.yy +# WORKING_DIRECTORY ${qjson_SOURCE_DIR}/lib/ +# ) + +# To regenerate json_scanner.cc use: +# flex json_scanner.yy + +set(qjson_MOC_HDRS + parserrunnable.h + serializerrunnable.h +) + +IF (NOT Qt5Core_FOUND) + qt4_wrap_cpp(qjson_MOC_SRCS ${qjson_MOC_HDRS}) +ENDIF() + +set (qjson_SRCS parser.cpp qobjecthelper.cpp json_scanner.cpp json_parser.cc parserrunnable.cpp serializer.cpp serializerrunnable.cpp) +set (qjson_HEADERS parser.h parserrunnable.h qobjecthelper.h serializer.h serializerrunnable.h qjson_export.h) + +# Required to use the intree copy of FlexLexer.h +INCLUDE_DIRECTORIES(.) + +add_gcc_compiler_cxxflags("-fexceptions") +remove_definitions(-DQT_NO_KEYWORDS) +add_library (qjson STATIC ${qjson_SRCS} ${qjson_MOC_SRCS} ${qjson_HEADERS}) diff --git a/src/http/qjson/FlexLexer.h b/src/http/qjson/FlexLexer.h new file mode 100644 index 000000000..bad4ce03f --- /dev/null +++ b/src/http/qjson/FlexLexer.h @@ -0,0 +1,206 @@ +// -*-C++-*- +// FlexLexer.h -- define interfaces for lexical analyzer classes generated +// by flex + +// Copyright (c) 1993 The Regents of the University of California. +// All rights reserved. +// +// This code is derived from software contributed to Berkeley by +// Kent Williams and Tom Epperly. +// +// Redistribution and use in source and binary forms, with or without +// modification, are permitted provided that the following conditions +// are met: + +// 1.
