Siaki le Malosi o Upu Fa'amatalaga ma le Javascript ma Fa'amatalaga masani (Fa'atasi ma Fa'ata'ita'iga Itu Tulaga, Foi!)

Sa ou faia ni suʻesuʻega i le sailia o se faʻataʻitaʻiga lelei o le siaki Malosi Upu e faʻaoga lea JavaScript ma Faʻamatalaga masani (Regex). I le tusi talosaga i laʻu galuega, matou te faia se faʻailoga i tua e faʻamaonia ai le malosi o le password ma e fai si faigata mo a matou tagata faʻaoga.

O le a le Regex?

O se faʻamatalaga masani o se faʻasologa o mataʻitusi e faʻamatalaina ai se suʻesuʻega. E masani lava, o ia ituaiga faʻataʻitaʻiga e faʻaaogaina e manoa suʻesuʻe algorithms mo maua or saili ma sui gaioiga i luga o manoa, pe mo le faʻaulufaleina sao. 

Lenei tusitusiga e mautinoa e le aʻoaʻoina oe masani masani. Naʻo le iloa o le agavaʻa e faʻaaoga ai Faʻamatalaga Masani o le a matua faʻafaigofieina lou atinaeina a o e suʻesuʻeina ni faʻataʻitaʻiga i tusitusiga. E taua foʻi le maitauina o le tele o gagana atiaʻe ua faʻamautinoaina le faʻaaogaina masani o faʻamatalaga… ae le o le faʻamamaina ma le suʻesuʻe o manoa i lea laasaga ma lea laʻasaga, Regex e masani lava ona sili atu le saoasaoa i le itu tautua ma le itu tagata o tausia.

Sa ou sailia le 'upega tafaʻilagi teisi ae ou te leʻi mauaina se faʻataʻitaʻiga o nisi lelei Faʻamatalaga Masani e vaʻai mo se tuʻufaʻatasia o le uumi, mataitusi, ma faʻailoga. Ae ui i lea, o le numera sa fai si tele tele mo loʻu tofo ma faʻapitoa mo .NET. Ma na ou faʻafaigofieina le numera ma tuʻu i le JavaScript. Ole mea lea e faʻamaonia ai le malosi ole password ile taimi moni ile browser a le tagata o tausia aʻo leʻi tuʻuina i tua ... ma avatua ni manatu ile tagata e faʻaaoga ile malosi ole password.

Taʻu se Upu Faʻamau

Faʻatasi ma ta taʻitasi o le piano feaveaʻi, e faʻataʻitaʻia le upu faʻasaga i le faʻaaliga masani ona tuʻuina mai lea o se tali i le tagata faʻaaoga i se aga i lalo ifo o le piano feaveaʻi.

Lenei o le Tulafono

le Faʻamatalaga masani fai se galuega manaia o le fa'aitiitiga o le umi o le code. O lenei galuega Javascript e siaki ai le malosi o se upu fa'aupuga ma pe fa'afefeteina e faigofie, feololo, faigata, pe faigata tele ona mate. A'o fa'apipi'i le tagata, e fa'aalia fautuaga i le fa'amalosia o ia ina ia malosi. E fa'amaonia le fa'aupuga e fa'atatau i:

• umi - Afai o le umi o loʻo i lalo pe sili atu i le 8 mataitusi.
• Tulaga Fefiloi – Afai o le upu faataga e iai mataitusi pito i luga ma mataitusi laiti.
• Numera – Afai o le upu faataga e aofia ai numera.
• Tagata Taua – Afai o le upu faataga e aofia ai mataitusi faapitoa.

O le galuega e faʻaalia ai le faigata faʻapea foʻi ma nisi faʻamatalaga i le faʻamaʻaina atili o le upu faʻamaonia.

Faʻaʻaʻaina Lau Talosaga Talosaga

E taua lou le gata i le faʻamaonia le fausiaina o upu i totonu o lau Javascript. O lenei mea e mafai ai e soʻo se tasi ma le suʻesuʻeina meafaigaluega atinaʻe ona aloese mai le tusitusiga ma faʻaaoga ai soʻo se upu latou te manaʻo ai. Oe tatau AUMAI taimi faʻaoga se server-itu siaki e faʻamaonia ai le malosi upu faʻatonu i luma o teuina i lau tulaga.
