本文实例为大家分享了thinkphp5微信扫码支付的具体代码，供大家参考，具体内容如下
配置WxPay.Config.php
控制器
//微信支付
//参数 订单 价格
public function wxPay($order_number,$money)
{
header("Content-type:text/html;charset=utf-8");
//require_once VENDOR_PATH.'/alipaymobile/config.php';
require_once VENDOR_PATH.'/wxpay/WxPay.Api.php';//引入微信支付
require_once VENDOR_PATH.'/wxpay/WxPay.Notify.php';
require_once VENDOR_PATH.'/wxpay/phpqrcode/phpqrcode.php';
$input = new \WxPayUnifiedOrder();//统一下单
$config = new \WxPayConfig();//配置参数
$notify = new \QRcode();
//$paymoney = input('post.paymoney'); //支付金额
$paymoney = $money; //测试写死
//$paymoney = 0.01; //测试写死
//$str = date('Ymd').substr(implode(NULL, array_map('ord', str_split(substr(uniqid(), 7, 13), 1))), 0, 8);//生成订单号
$out_trade_no = $order_number; //商户订单号(自定义)
$goods_name = '扫码支付'.$paymoney.'元'; //商品名称(自定义)
$input->SetBody($goods_name);
$input->SetAttach($goods_name);
$input->SetOut_trade_no($out_trade_no);
$input->SetTotal_fee($paymoney*100);//金额乘以100
$input->SetTime_start(date("YmdHis"));
$input->SetTime_expire(date("YmdHis", time() + 600));
$input->SetGoods_tag("test");
//回调地址 注意能访问
$input->SetNotify_url("http://www.域名.com/index.php/index/index/wxpaynotifyurl"); //回调地址
$input->SetTrade_type("NATIVE");
$input->SetProduct_id('123456789');//商品id
$result = \WxPayApi::unifiedOrder($config, $input);
if($result['result_code']=='SUCCESS' && $result['return_code']=='SUCCESS') {
$url = $result["code_url"];
$this->assign('money',$paymoney);
$this->assign('url',$url);
$this->assign('num',$out_trade_no);
//映射视图 微信二维码需要自己生成
return view("../../../template/wxpay");
}else{
$this->error('参数错误');
}
// return view();
}
视图 生成二维码 进行扫描付款
