1. 登录支付宝开发者中心，创建应用，开通App支付功能，配置密钥
   详见[支付宝官方文档](https://opendocs.alipay.com/open/204/105297/)

2. 在manifest.json文件“App模块配置”项的“Payment(支付)”下，勾选“支付宝支付”项

3. 通过服务器生成支付订单,参考:
   [生成支付订单示例(PHP)](https://github.com/dcloudio/H5P.Server/tree/master/payment/alipayrsa2)
   [老版本"移动快捷支付"示例代码(PHP)](https://github.com/dcloudio/H5P.Server/tree/master/payment/alipay)
   [生成支付订单示例(C#)](http://ask.dcloud.net.cn/article/197)

4. 应用中调用支付功能
  * uni-app项目示例
``` js
uni.getProvider({
   service: 'payment',
   success: function (res) {
     console.log(res.provider)
     if (~res.provider.indexOf('alipay')) {
       uni.requestPayment({
         "provider": "alipay", 
         "orderInfo": orderInfo, //此处为服务器返回的订单信息字符串
         success: function (res) {
           var rawdata = JSON.parse(res.rawdata);
           console.log("支付成功");
         },
         fail: function (err) {
           console.log('支付失败:' + JSON.stringify(err));
         }
       })
     }
   }
});
```
  * 5+项目示例
``` js
//获取支付渠道
var alipaySev = null;
plus.payment.getChannels(function(channels) {
  for (var i in channels) {
    var channel = channels[i];
    if (channel.id === 'alipay') {
      alipaySev = channel;
    }
	}
}, function(e) {
	console.log("获取支付渠道失败：" + e.message);
});
//发起支付
var statement = orderInfo; //此处为服务器返回的订单信息字符串
plus.payment.request(alipaySev, statement, function(result) {
    var rawdata = JSON.parse(result.rawdata);
    console.log("支付成功");
}, function(e) {
    console.log("支付失败：" + e.message);
});
```
