关于移动端的支付我们可以去看一下官方文档(传送门)
看过之后,我们使用官方的提供的demo进行测试,是没有问题的,但是官方提供的SDK包含的文件非常的多,于是就有了合成精简版,该代码来自网络,我进行了部分修改(一点点哈哈哈
付款界面 当然了这个是沙箱 hahh
简要说明
其中$_GET['quit_url']是当支付完成时候点击完成或退回时,回跳的地址,有人说$returnUrl不就行了…hahah,其实这个也可以的,但是对于H5来说就不怎么友好了(跳回来的时候带了一大堆参数)….
就是支付成功之后点击完成跳回的页面
还有一个地方要注意的是下面这段代码,如果使用正式支付的话记得将网关地址改为正式的地址,演示的为沙箱的地址,此处根据需求自行更改
public function __construct()
{
$this->charset = 'utf-8';
$this->gatewayUrl = 'https://openapi.alipaydev.com/gateway.do'; // 网关地址 沙箱与正式的不同 请区分填写
}
哦哦哦,对了没有写回调文件,这个自己写一下就完事了,这里就不贴代码了
