TP6 生成Qrcode二维码和Barcode条形码的方法

运行命令下载：composer require codeitnowin/barcode

注：好像已经不可用，如不可以下载那就从以下网址下载吧

下载地址一：https://github.com/codeitnowin/barcode-generator

下载地址二：https://pan.baidu.com/s/1-hFWYfed4y3YkWKLz2o75g

手动下载完后解压缩，将codeitnowin文件整个拷贝到项目的扩展文件夹extend中，如下图：

二维码和条形码生成代码如下：

	private function hex2rgba($hexColor='#000',$a=0)
	{
	    $color = str_replace('#','',strtoupper(trim($hexColor)));
	    if(strlen($color)>3){
	        $rgba=array(
	            'r'=>hexdec(substr($color,0,2)),
	            'g'=>hexdec(substr($color,2,2)),
	            'b'=>hexdec(substr($color,4,2)),
				'a'=>$a

	    }else{
	        $rgba=array(
	            'r'=>hexdec(substr($color,0,1). substr($color,0,1)),

}

效果如下：
