先说点啥吧~~~
分配任务的时候，被分配到了这个微信H5的支付，emmm 没有给demo，所以就去网上找了微信H5支付的demo，说实话，之前多少接触了一下支付(写了一个游戏的支付，虽然垃圾但是多少接触了一下支付)，刚接触微信H5 想着去官方拿一下SDK看一看，然后把需要的摘出来，放到项目中就完事了…结果官方没有提供H5支付的demo
好嘛，没提供那就只能去网上搜索了，万能的网友肯定有啊
搜了一大堆，没有能用的,在我大脑崩溃之际还是发现了一个可以用的
简直是救星啊
展示
因为我还没开通H5的支付 所以提示这样的，开通的话返回的里面会有地址链接,拿到链接我们做跳转就行
好了扯完犊子了，咱就谈正事~~
调用
总共是两个文件,复制代码,建好两个文件之后,访问下面这个,也就是第一个就可以看到结果了,当然那些配置需要你们自己配(appid、mchid、key)
<?php
namespace weixinpayApp;
include 'wechatH5Pay.php';
class wxh5{
//$data 金额和订单号
public function wxh5Request(){
/// 下面这三样是你们申请的账号啦 密钥啦
$appid = '公众号 也就是appid';
$mch_id = '商户号 ';//商户号
$key = '密钥';//商户key
$notify_url = "";//回调地址
$wechatAppPay = new \wechatAppPay($appid, $mch_id, $notify_url, $key);
$params['body'] = '诺基亚手机就是牛'; //商品描述
$params['out_trade_no'] = "zhiyu".time(); //自定义的订单号
// !*!*!*!*!*!这个地方需要注意，如果传进来的金额单位是元,则需要 $money*100 转化为分 数字必须为整数 !*!*!*!*!*!
$params['total_fee'] = '1'; //订单金额 只能为整数 单位为分
$params['trade_type'] = 'MWEB'; //交易类型 JSAPI | NATIVE | APP | WAP
$params['scene_info'] = '{"h5_info": {"type":"Wap","wap_url": "https://fzxywl.cn","wap_name": "诺基亚就是牛"}}';
$result = $wechatAppPay->unifiedOrder( $params );
var_dump($result);
exit;
$url = $result['mweb_url'].'&redirect_url=https%3A%2F%2Ffzxywl.cn';//redirect_url 是支付完成后返回的页面
var_dump($url);
return $url;
}
}
$k = new wxh5();
$k -> wxh5Request();

这两个都给了，放到项目中还是什么的就看你们自己发挥啦~~
当然，我这是看到别人写的~~
