一、使用实例
官方信息:
二、服务端
1.下载SDK
App 支付服务端 DEMO&SDK | 开放平台
根据自身的需要选择SDK包
下载之后放在了 vendor 文件下:
2.业务层
支付宝证书模式下的配置参考跳转:https://mp.csdn.net/mp_blog/creation/success/127964188

3.业务层返回实例
返回的和APP支付文档上不一样哦,这里返回的是一串请求字符串,我们给前端客户端去请求支付宝
可以参考官方文档:APP 支付快速接入 | 网页&移动应用
"alipay_root_cert_sn=6***支付宝根路径证书提取的序列号&alipay_sdk=alipay-sdk-php-2020-04-15&app_cert_sn=证书序列号&app_id=2021*****&biz_content=%7B%22total_amount%22%3A%220.01%22%2C%22product_code%22%3A%22QUICK_MSECURITY_PAY%22%2C%22subject%22%3A%22%5Cu6d4b%5Cu8bd5%5Cu5546%5Cu54c1%22%2C%22out_trade_no%22%3A1672109672%7D&charset=utf-8&format=json&method=alipay.trade.app.pay¬ify_url=****&sign_type=RSA2×tamp=2022-12-27+10%3A54%3A32&version=1.0&sign=sign"
推荐使用联调工具:
https://opensupport.alipay.com/support/tools/cloudparse/interface?ant_source=antsupport
4.回调层
/**
* @method app - pay 回调
*/
public function appPayNotify()
{
// 打个日志看看
$sFileName = 'alipay.txt';
$sContent = date('Y-m-d H:i:s') . '开始回调\r\n' . '\r\n';
file_put_contents($sFileName, $sContent, FILE_APPEND);
// 回调参数根据文档上的异步回调通知看看自己需要的参数接收用 POST 接收过来就行
$notifyTime = $_POST['notify_time']; // 回调时间
$notifyType = $_POST['notify_type']; // 通知类型
$notifyId = $_POST['notify_id']; // 通知检验 ID
$appId = $_POST['app_id']; // 支付宝分配给开发者的应用 APPID
$authAppId = $_POST['auth_app_id']; // 开发者的 app_id,在服务商调用的场景下为授权方的 app_id
$tradeNo = $_POST['trade_no']; // 支付宝交易凭证号
$orderNo = $_POST['out_trade_no']; // 原支付请求的商家订单号
// 打个日志看看
$sFileName = 'alipay.txt';
$sContent = date("Y-m-d H:i:s") . '接收到_POST方式回调参数\r\n' . json_encode($orderNo, JSON_UNESCAPED_UNICODE) . '\r\n';
file_put_contents($sFileName, $sContent, FILE_APPEND);
// 接收到回调之后输出 success 给支付宝
echo 'success';
die;
}
三、客户端
绑定方法之后使用APP 自带的 uni.requestPayment方法来发起
// 购买执行
async actionRpBuy() {
if (this.num == '' || this.num == 0) {
uni.showToast({
title: '请选择购买数量',
icon: 'none'
});
return false;
}
request({
url: '/请求地址',
}).then(res => {
if (res.code == 1) {
console.log(res.data);
uni.requestPayment({
provider: 'alipay', //'alipay','wxpay'// manifest.json->APP模块配种->payment配置一下
orderInfo:res.data, // 这个参数给后端返回的请求字符串
success: res => {
uni.navigateTo({
url: '../CompletionOfPayment/CompletionOfPayment'
})
},
fail: err => {
let orderId = this.ids
uni.showModal({
// title: '提示',
title: err,
content: '支付失败',
success: function(res) {
if (res.confirm) {} else if (res.cancel) {}
}
})
}
})
}
})
},
