基于ThinkPHP5实现【二维码生成】严格按照TP5框架目录方式上传

有些功能大家可以加以修改直接做成一个公共接口，放在application的common.php中，这样在其他控制器的方法中有需要调用的时候，直接传入参数进行调用

QR Code

This library helps you generate QR codes in a jiffy. Makes use of bacon/bacon-qr-code to generate the matrix and khanamiryan/qrcode-detector-decoder for validating generated QR codes. Further extended with Twig extensions, generation routes, a factory and a Symfony bundle for easy installation and configuration.

composer require deng-tp5/qr-code

common.php

$url = 'myphp.vip';
create_qrcode($url);        //  引用commmon里的方法 

/**
 * 生成二维码公共方法
 * @param $url
 * @return \Endroid\QrCode\Response\QrCodeResponse
 * @throws \Endroid\QrCode\Exception\InvalidPathException
 * @author:  deng    (2019/7/17 16:04)
 */
function create_qrcode($url)
{
    $condition['text'] = $url;
    return QrCodeDeng::createQrcodeAdvanced($condition);
}

===============================================

Installation

Use Composer to install the library.

$ composer require endroid/qr-code

Basic usage

use Endroid\QrCode\QrCode;

$qrCode = new QrCode('Life is too short to be generating QR codes');

header('Content-Type: '.$qrCode->getContentType());
echo $qrCode->writeString();

Advanced usage

use Endroid\QrCode\ErrorCorrectionLevel;
use Endroid\QrCode\LabelAlignment;
use Endroid\QrCode\QrCode;
use Endroid\QrCode\Response\QrCodeResponse;

// Create a basic QR code
$qrCode = new QrCode('Life is too short to be generating QR codes');
$qrCode->setSize(300);

// Set advanced options
$qrCode->setWriterByName('png');
$qrCode->setMargin(10);
$qrCode->setEncoding('UTF-8');
$qrCode->setErrorCorrectionLevel(new ErrorCorrectionLevel(ErrorCorrectionLevel::HIGH));
$qrCode->setForegroundColor(['r' => 0, 'g' => 0, 'b' => 0, 'a' => 0]);
$qrCode->setBackgroundColor(['r' => 255, 'g' => 255, 'b' => 255, 'a' => 0]);
$qrCode->setLabel('Scan the code', 16, __DIR__.'/../assets/fonts/noto_sans.otf', LabelAlignment::CENTER);
$qrCode->setLogoPath(__DIR__.'/../assets/images/symfony.png');
$qrCode->setLogoSize(150, 200);
$qrCode->setRoundBlockSize(true);
$qrCode->setValidateResult(false);
$qrCode->setWriterOptions(['exclude_xml_declaration' => true]);

// Directly output the QR code
header('Content-Type: '.$qrCode->getContentType());
echo $qrCode->writeString();

// Save it to a file
$qrCode->writeFile(__DIR__.'/qrcode.png');

// Create a response object
$response = new QrCodeResponse($qrCode);

Built-in validation reader

You can enable the built-in validation reader (disabled by default) by calling setValidateResult(true). This validation reader does not guarantee that the QR code will be readable by all readers but it helps you provide a minimum level of quality.

The readability of a QR code is primarily determined by the size, the input length, the error correction level and any possible logo over the image so you can tweak these parameters if you are looking for optimal results. You can also check $qrCode->getRoundBlockSize() value to see if block dimensions are rounded so that the image is more sharp and readable.

Take note that the validator can consume quite amount of additional resources.

Symfony integration

The endroid/qr-code-bundle integrates the QR code library in Symfony for an even better experience.

Configure your defaults (like image size, default writer etc.)
Generate QR codes quickly from anywhere via the factory service
Generate QR codes directly by typing an URL like /qr-code/<text>.png?size=300
Generate QR codes or URLs directly from Twig using dedicated functions

Read the bundle documentation for more information.
