  1. Advanced Web Server/HTTP Server AWS/HTTP Server – how do they differ? The Net+Works Windows Utility AWS/Pbuilder HTTP server

  2. Advanced Web Server/HTTP Server Differences • HTTP Server • Uses HTML-to-C utility • Provides solid basic server • AWS Server • Uses Pbuilder utility • Provides advanced features • HTTP v1.1 compatibility • File upload • File system stubs • External CGI • Cookies • Web content compression

  3. Net+Works Windows Utility • Access either HTTP Server (HTML->C) or AWS (Pbuilder) utility • Use the App Wizard to construct your Server application • Use FTP-> to load your Server application to the board

  4. Advanced Web Server

  5. AWS/pbuilder • Not needed unless interaction • Pbuilder will compile html • All tags must have an <!– RpEnd  • Space required after !— • Space required before  • RpEnd follows the html command • Rppages.c and PbSetUp.txt lines need <cr><lf> • Basic format • <!– RpCommand  • Some html • <!– RpEnd 

  6. Running pbuilder Add new pbuilder commands Image files (.jpeg, .bmp) html files New html files File.pbb pbuilder Pbsetup.txt

  7. Running pbuilder pbuilder Rpsetup.txt rppages.c c files _v.c files Place modules Into separate file Project

  8. HTTP Project Structure All Additional Application C Files Additional Library File

  9. Creating your utility programs • Aka filling in the stub programs • Copy stubs to new file • Fill in the stubs • When done, use DontCreateVariablesFile • Use std c commands • For “get” commands, replace the default variable with your own char * • Start small/simple

  10. Review an existing application • html code • pbuilder calls • Application modules (filled out routines) • rppages.c

  11. Hints and Kinks • Do • Always generate the html first • Always use a batch file • Create subroutines in separate files • Use PbSetUp.txt file • RpSetUp.txt/rppages.c lines must end with <cr><lf>

  12. Hints and Kinks • Don’t • Fill out subroutines in _v.c files • Develop without a batch file

  13. HTTP Server

  14. Fill-in Dynamic Function Calls in the C Source Code Link in httpd.a HTML to C Utility Web Page(s) • Web Page _*.c files • URL.C • bindata.c Integrating an HTTP Server Baseline Application Kernel, Stack, BSP

  15. Net+Os v6.0 Enhancements File System

  16. HTTP Server (File System) • This’s actually RomPager file system interface • RomPager handles POP3, SMTP & HTTP server. • Define APP_FILE_SYSTEM in file.c or application build file • Upload file to the file system from web pages • Download files from the file system • Use “FS” prefix to access any files in the file system.

  17. HTTP Server (File System) Upload • Only MULTIPART/FORM-DATA of ENCTYPE is supported for file upload • Use web page access value • Multiple access values / no web page access • Use the same group id of a directory where a file or directory is created to • Use default value (from RpHSSetDefaultGroupId) for creating a file/directory in ROOT directory

  18. HTTP Server (File System) Download • User is prompted for username/password when downloading a file • Username/password is not required when a file can be accessed from the default permission (from RpHSSetDefaultGroupId)

  19. HTTP Server (File System) • RpHSSetCurrentDirectory • Setup the directory for the current connection • RpHSGetErrorStatus • Get the status for the current connection • RpHSSetDefaultGroupId • Setup default group id. • This group id is used for retrieving a file. If a file can be retrieved for the default group id access, no username or password is required. • RpHSGetDefaultGroupId • Return default group id
