创建支付订单，完成付款
<p>因为H5 APP创建支付订单的后端WEB方法可以使用之前安卓项目的WEB方法，所以不需要再创建，只需要写好uni-app的订单页面代码即可。</p>
<pre><code class="language-javasript">uni.request({
url: that.url.zfb.appPayOrder,
method: "POST",
header: {
"token": uni.getStorageSync("token")
},
data: {
"orderId": id
},
success: function(resp) {
let orderString = resp.data.orderString
const jyAliPay = uni.requireNativePlugin('JY-ALIPAY')
jyAliPay.show({
// 发起支付
if_sanbox: true,
auto_create_order_info: false,
appid: that.zfb.app.appid,
rsa2_private: that.zfb.app.privateKey,
order_info: orderString
}, function(result) {
// 支付完成回调
// console.log(result)
if (result.resultStatus == '9000') {
uni.showToast({
title: "付款成功"
})
uni.request({
url: that.url.zfb.updateOrderStatus,
method: "POST",
header: {
"token": uni.getStorageSync("token")
},
data: {
"orderId": id
},
success: function(resp) {
that.loadData()
}
})
} else {
uni.showToast({
title: "付款失败",
icon: "none"
})
}
});
}
)</code></pre>
<p>如果在非沙箱环境中使用支付宝付款，代码应该这样写：</p>
<pre><code class="language-javascript">uni.requestPayment({
provider:"alipay",
orderInfo:orderString,
success:function(){
},
fail:function(){
}
})</code></pre>
