AppML-gevalle
Hierdie gevallestudie demonstreer hoe om internettoepassings te bou deur AppML te gebruik.
Deel I: Toegang tot internetlêers
- Toegang tot 'n TEXT-lêer
- Toegang tot 'n XML-lêer
- Toegang tot 'n JSON-lêer
Deel II: Toegang tot internetdatabasisse
- Lys databasis data
- Filtreer databasis data
- Redigeer databasisdata
AppML-blaaier en AppML-bediener
In hierdie gevallestudie loop AppML beide in die blaaier (appml.js) en op die bediener (appml.php).
Ons sal 'n webbediener gebruik wat by https://www.w3schools.com geleë is .
Al die lêers en databasisse is op die bediener geleë.
Later in hierdie tutoriaal sal jy leer hoe om 'n webbediener in die blaaier te simuleer.
