BREW开发参考代码

GENERAL DESCRIPTION: This BREW Applet illustrates usage of BREW's IWeb Shows usage of BREW's IWeb interface. It's a simple URL fetcher/shower. The IWeb interface is designed to speed development of web-protocol aware applications. IWeb handles many mundane chores of the protocol part of a web browser, such as HTTP keep-alives and HTTP proxying. FILES ON PHONE: webber.mod webber.bar USAGE: Webber has 2 modes: URL entry and URL fetching/dumping. When webber starts, you'll be in URL entry mode. You'll see a text entry dialog into which you may enter a URL, or, by pressing UP and DOWN, select from a pre-stored "history list". Once you've entered or selected a URL, press SELECT. The menu bar at the bottom should have a "Go!" item and a text-entry-mode item. Select "Go!" and press SELECT again. Now you're in URL fetch/dump. Webber will fetch the URL and print the results. Pressing '#' while in this mode toggles content dumping, so pressing '#' will show the headers and body of the fetched URL. By default, though, dumping is off, so all you'll see is status messages, and while fetching the body, hashmarks every 512 bytes of body. UP and DOWN keys while in fetch mode scroll the displayed text. Pressing SELECT while in fetch/dump mode restarts the last URL fetch. Pressing BACK returns you to the text edit control, where the last URL you fetched is at the bottom of the history list, and is displayed.
