Tautan menyusut tanpa lemak (F3)



Tidak memalukan untuk mempersingkat tautan di 13, bukan? Seorang pemula, dan bukan hanya seorang pemula, harus mencoba menulis Link Tamer Anda sendiri sambil mempelajari kerangka kerja baru. Itulah yang saya lakukan. Apa yang bisa saya katakan - bootstrap kelima, kerangka bebas lemak dan sepotong jiwa.



Ini kodenya . Untuk pembaca seperti saya;)



Sebuah kerangka, bukan?



Laravel — 65- FatFreeFramework. Python Flask, , - :



#  
@app.route('/')
def hello_world():
    return 'Hello, World!'





//  
$f3->route('GET /',
    function() {
        echo 'Hello, world!';
    }
);


, . .zip ., , . index.php /ui.

  • Larang pembuatan tautan ke layanan pemendekan itu sendiri, buat daftar sumber daya yang "dilindungi" dari pemendekan
  • Saya sangat menyarankan bahwa meskipun dalam masalah kecil untuk melakukan validasi input di sisi server, dengan output dari kesalahan yang sesuai, Anda tidak boleh mengandalkan penambahan atribut yang diperlukan dan type = "url" ke kolom input
