Sezvo ini ndine imwe nguva yemahara yekuzorora (kubva pakuita mapurojekiti kana kwechinguva), ndafunga kunyora chinyorwa ichi (kana zvimwe zvinyorwa) nezve webhu kuvandudza neFlask (Python). Ini handisi kuzomira kuti nditsanangure chinonzi Flask, ivo vanoto tsanangura izvo mu Hypertext uye ivo vanoitsanangura zviri nani kupfuura ini.

Mhoro Nyika

MuFlask tinogona kugadzira iyo yakasarudzika "Mhoro Nyika" nenzira inotevera:

Isu tinongochengetedza kodhi yedu saiti hello.py uye nekumhanya nayo

$ python hello.py
* Running on http://localhost:5000/

Iye zvino chikumbiro chedu chiri kumhanya pa http: // localhost: 5000 /

Nhanho 0: kugadzira maforodha

Tisati tatanga, tinoda anotevera maforodha ekushandisa kwedu:

Iyo Project dhairekodhi inogona kunge iine chero zita raunoda, ingori dhairekitori paunenge uine application yako. Mune iyo tuli faira ichave mafaira anowanikwa kune vashandisi kuburikidza neHTTP. Ndiyo nzvimbo iyo iwe yaunofanirwa kuisa yako css uye js mafaera. Iwo matemplate dura ndiko uko matemplate (iyo html5) yechako chishandiso ichave iri.

Nhanho I: Dhatabhesi schema

Tichatanga kugadzira database schema. Zvekushandisa izvi isu tinongoda chete database. Ingoisa inotevera kodhi mune faira rakanzi "schema.sql" muProjekita dhairekitori.

Ichi chirongwa chine tafura imwechete inonzi zvinongedzo uye mutsara wega wetafura iyi une chitupa, zita uye chinyorwa. Ichi ID iri auto inowedzera manhamba uye yakakosha kiyi, mamwe maviri tambo.

Nhanho yechipiri: Chekutanga kodhi yekushandisa

Iye zvino zvatine schematic tinogona kugadzira module yekushandisa. Ngatizvidaidze kuti flaskr.py, iyo inofanirwa kunge iri mukati meProjekita dhairekitori. Kutanga isu tiri kuzowedzera zvinodikanwa zvinotengwa kunze kwenyika, pamwe nechikamu chekumisikidza. Mukushandisa kudiki tinogona kusiya gadziriso yakanangana nemu module yatichaita. Nekudaro, yakanyanya kunaka uye yakanyatsoita ndeyekugadzira iyo .ini kana

Mune iyo flaskr.py faira:

Chakavanzika_key inodiwa kuchengetedza zvikamu zvakachengeteka. Sarudza kiyi iyi zvine hungwaru. Iyo debug mureza inogonesa kana kuremadza iyo inofambidzana debugger. Usambofa wakasiya kukanganisa pagadziriro yekugadzira, sezvo ichizobvumira vashandisi kumhanyisa kodhi pane yako server!

Iye zvino isu tinogona kugadzira yedu yekushandisa uye titange neyakagadziriswa mu flaskr.py:

Tiri zvakare kuwedzera nzira yekubatanidza nyore nyore kune yakatarwa dhatabhesi. Izvi zvinogona kushandiswa kuvhura chinongedzo pakukumbira. Izvi zvichauya zvinobatsira gare gare.

Pakupedzisira isu tinowedzera tambo panoperera iyo faira ichaitwa neseva kana tichida kuendesa iyo faira seyakazvimiririra application:

Nezvo iwe unofanirwa kukwanisa kuvhura chishandiso pasina matambudziko. Iye zvino tinoshandisa rairo inotevera:

$ python flaskr.py

Iwe uchaona meseji inoratidza kuti sevha yatanga pamwe neiyo URL.

Kana isu tikasvika URL, inotipa 404 kukanganisa, sezvo tisina webhusaiti parizvino. Asi isu tichaisa pfungwa pane izvo zvishoma gare gare. Kutanga isu tinofanirwa kuita kuti dhatabhesi rishande.

Nhanho III: Gadzira iyo dhatabhesi
