/* =============================================================================== GSOAP WININET PLUGIN ------------------------------------------------------------------------------- Allow gsoap clients (not servers) to direct all communications through the WinInet API. This automatically provides all of the proxy and authentication features supported by the control panel 'Internet Options' dialog to the client. As these options are shared by IE, this means that "if IE works, gsoap works." Project Home: http://code.google.com/p/gsoapwininet/ ------------------------------------------------------------------------------- Features ------------------------------------------------------------------------------- + gsoap plugin - extremely easy to use + complete support for: - HTTP/1.0 and HTTP/1.1 - HTTPS (no extra libraries are required) - HTTP authentication - Proxy servers (simple, automatic discovery, etc) - Proxy authentication (basic, NTLM, etc) + authentication prompts and HTTPS warnings (e.g. invalid HTTPS CA) can be resolved by the user via standard system dialog boxes. + message size is limited only by available memory + connect, receive and send timeouts are used + supports all SOAP_IO types (see limitations) + written completely in C, can be used in C, C++, and MFC projects without modification (anywhere that gsoap is used) + can be used in both MBCS and UNICODE projects + compiles cleanly at warning level 4 (if gsoap uses SOAP_SOCKET for the definition of sockets instead of int, it will also compile without win64 warnings). + all debug trace goes to the gsoap TEST.log file + supports multiple threads (all plugin data is stored in the soap structure - no static variables) ------------------------------------------------------------------------------- Limitations ------------------------------------------------------------------------------- - DIME attachments are not supported - may internally buffer the entire outgoing message before sending (if the serialized message is larger then SOAP_BUFLEN, or if SOAP_IO_CHUNK mode is being used then the entire message will be buffered) ------------------------------------------------------------------------------- Usage ------------------------------------------------------------------------------- Add the gsoapWinInet2.h and gsoapWinInet2.cpp files to your project (if you have a C project, rename gsoapWinInet2.cpp to .c and use it as is). Ensure that you turn off precompiled headers for the .cpp file. In your source, just after calling soap_init(), register this plugin with soap_register_plugin( soap, wininet_plugin ). For example: struct soap soap; soap_init( &soap ); soap_register_plugin( &soap, wininet_plugin ); soap.connect_timeout = 5; // this will be used by wininet too ... soap_done(&soap); ------------------------------------------------------------------------------- Notes ------------------------------------------------------------------------------- For extra control, you may also register this plugin using the soap_register_plugin_arg() function, and supply as the argument flags which you want to be passed to HttpOpenRequest. For example: struct soap soap; soap_init( &soap ); soap_register_plugin_arg( &soap, wininet_plugin, (void*) INTERNET_FLAG_IGNORE_CERT_CN_INVALID ); See the MSDN documentation on HttpOpenRequest for details of available flags. The header file is required for the definitions of the flags. Some flags which may be useful are: INTERNET_FLAG_KEEP_CONNECTION Uses keep-alive semantics, if available, for the connection. This flag is required for Microsoft Network (MSN), NT LAN Manager (NTLM), and other types of authentication. ++ Note that this flag is used automatically when soap.omode has the SOAP_IO_KEEPALIVE flag set. ++ INTERNET_FLAG_IGNORE_CERT_CN_INVALID Disables Microsoft Win32 Internet function checking of SSL/PCT- based certificates that are returned from the server against the host name given in the request. INTERNET_FLAG_IGNORE_CERT_DATE_INVALID Disables Win32 Internet function checking of SSL/PCT-based certificates for proper validity dates. This plugin uses the following callback functions and is not compatible with any other plugin that uses these functions. soap->fopen soap->fposthdr soap->fsend soap->frecv soap->fclose If there are errors in sending the HTTP request which would cause a dialog box to be displayed in IE (for instance, invalid certificates on an HTTPS connection), then a dialog will also be displayed by this library. At the moment is is not possible to disable the UI. If you wish to remove the UI then you will need to hack the source to remove the dialog box and resolve the errors programmatically, or supply the appropriate flags in soap_register_plugin_arg() to disable the unwanted warnings. Because messages are buffered internally to gsoapWinInet2 plugin it is recommended that the SOAP_IO_STORE flag is not used otherwise the message may be buffered twice on every send. Use the default flag SOAP_IO_BUFFER, or SOAP_IO_FLUSH. ------------------------------------------------------------------------------- License ------------------------------------------------------------------------------- The licence text below is the boilerplate "MIT Licence" used from: http://www.opensource.org/licenses/mit-license.php Copyright (c) 2009, Brodie Thiesfield Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
