创建支付订单
<h3>封装创建支付订单的WEB方法</h3>
<p>编写ZfbController.java中的方法</p>
<pre><code class="language-java">@Login
@PostMapping("/appPayOrder")
@ApiOperation("App程序付款")
public R appPayOrder(@RequestBody PayOrderForm form, @RequestHeader HashMap header) {
ValidatorUtils.validateEntity(form);
String token = header.get("token").toString();

}
//验证购物券是否有效
//验证团购活动是否有效

<h3>前端发起支付请求</h3>
<p>编写order.js文件</p>
<pre><code class="language-javascript">$(".pay-btn").click(function(){
//支付宝
let orderId=$(this).parents(".order").data("order-id")
$.ajax({
url:url.zfb.appPayOrder,
type:"post",
dataType:"json",
contentType:"application/json",
beforeSend:function(request){
request.setRequestHeader("token",localStorage.getItem("token"))
},
data:JSON.stringify({
"orderId":orderId
}),
success:function(resp){
let orderString=resp.orderString
window.order.pay(orderString,localStorage.getItem("token"),orderId)
}
})</code></pre>
