###微信公众号内用户进行确认下单页面
1、下载集成微信公众号的帮助包并将文件放入项目文件夹中
ap.js 跳转到自带浏览器js
pay.htm 提示用户跳转htm页面
1、使用pageExecute方法，以GET方式获得url字符串；这个就得到了拼接好的支付url返回前台a标签里面就可以了
|
1
2
|
AlipayTradeWapPayResponse response = client.pageExecute(request,null,"GET");
test = response.Body;
|
2、将Url传入前台页面标签，待用户点击确定
|
1
|
<a id="test" href="<%=test%>" class="button button-big button-fill">支付宝结算
</a>
|
3、用户点击页面后跳转到提示页，提示用户使用手机自带浏览器打开连接
4、完成支付
5、整体的代码
前端

总结及出现的问题
1、参数的内容
按照api提供的列表把必填项的key及value一定要写全，写对；
2、BizContent的业务参数内多个参数之间用“，”号隔开，之前忘记写全，报错；
3、签名错误
sign_valid
API里面生成签名，包括sign_type
接收支付宝的异步通知时，验签之前不包括sign 和 sign_type
签名sign生成规则
支付宝官方sdk有个bug，Aop.Api.Util.AlipaySignature类中方法没有去掉sign_type就进行验证，导致出错；

4、交易订单处理失败 请稍后再试 ali38173
转到支付宝时，弹出这个错误，找了很久，才发现是由于Bizcontent的最后一个}括号内包含一个全角的空格，很坑啊；
