Pembaca kode qr php open source

Ya memang, saya menggunakan Rogue Master 0. 63. 2-0728-RM-T. Intinya, saya membuat file yang berisi sinyal suara monoton yang dibuat oleh ggwave. Namun, secara default ggwave menulis file WAV 16-bit, dan memainkan ini tidak didukung (disebutkan dalam kode) dan menghasilkan keluaran yang cukup kacau. Tapi saya mendapatkan output

Jika Anda ingin menggunakan framework PHP Laravel untuk membangun barcode web dan pembaca kode QR, Anda dapat mengimplementasikan logika kode baik di sisi klien atau di sisi server. Dynamsoft menyediakan berbagai SDK untuk berbagai platform. desktop, seluler, dan web. Pada artikel ini, kami fokus pada cara memanfaatkan ekstensi PHP yang dibuat dengan Dynamsoft C++ Barcode SDK untuk membaca kode batang dan kode QR di sisi server. Jika pemrograman sisi klien web adalah tipe Anda, silakan merujuk ke https. // www. dynamsoft. com/barcode-reader/sdk-javascript/

Langkah-Langkah Implementasi Pembacaan Kode QR Server Side Barcode Menggunakan PHP Laravel

Dalam paragraf berikut, kami akan memandu Anda melalui proses pengembangan proyek PHP Laravel yang dapat membaca kode batang dan kode QR dari file gambar di sisi server

Langkah 1. Instal Ekstensi Pembaca Kode QR Barcode PHP

Tidak ada paket biner pra-bangun. Untuk membaca kode batang dan kode QR di PHP, Anda perlu membuat dan memasang ekstensi PHP dari kode sumber di Windows dan Linux

Langkah 2. Perancah Proyek Laravel

Setelah ekstensi diinstal, Anda dapat memulai proyek Laravel baru

composer create-project laravel/laravel web-barcode-qrcode-reader

Perintah di atas menginstal Laravel versi stabil terbaru. Untuk menghindari masalah kompatibilitas, cara yang lebih baik adalah menentukan nomor versi Laravel

php artisan --version
Laravel Framework 8.83.23

composer create-project laravel/laravel:^8.0 web-barcode-qrcode-reader

Langkah 3. Buat Pengontrol

Pengontrol Laravel menangani permintaan HTTP. Kami dapat membuat pengontrol untuk menangani file gambar yang diunggah dan mengembalikan hasil decoding kode batang dan kode QR

php artisan make:controller ImageUploadController

Perintah menghasilkan file

  php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
  php -r "if (hash_file('sha384', 'composer-setup.php') === '55ce33d7678c5a611085589f1f3ddf8b3c52d662cd01d4ba75c0ee0459970c2200a51f492d557530c71c15d8dba01eae') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
