springMVC后端接入支付宝,微信

近期项目要求打通支付宝支付和微信支付，所以趟了一趟接入支付的浑水：

支付宝接入流程

微信支付流程

分析完之后就对照官方的文档开始行动了

一：支付宝支付

打开支付宝
选择商家平台
选择手机网站支付如下操作

https://b.alipay.com/signing/productDetail.htm?productId=I1011000290000001001

选择手机网站支付，填写资料

填写后等待审核通过

然后进入开放平台->开发者中心->网页&移动应用，

然后创建应用

然后点击进入查看详情

然后添加手机网站支付功能

然后点击应用信息访问进行开发配置

在配置上图的回调地址和密钥，接下来就是开发了

这里有官方的demo

https://docs.open.alipay.com/270/106291/

二、微信支付

接下来介绍微信支付，微信支付没有官方的demo

比较蛋疼，踩过很多的坑

支付宝支付相对接入比较容易，微信支付需要分微信内打开和微信外打开，微信内走公众号支付，微信外走H5支付，刚开始接入的时候发现H5链接在微信内打开支付不了才知道微信内强制走的是公众号支付，这一点不知道可能让你的功能在提测的时候不通过，或者延期

先到微信公众平台

申请开通公众号支付和H5支付

然后配置

添加公众号授权，然后就是接入开发了

微信或者支付宝下单/支付回调

支付宝下单后生产预付单，接口会生成form数据，通过js自动提交（<form> ...submit</form>）

微信支付分为H5支付和公众号支付

H5支付在微信内是不能支付支付成功的，微信会强制在微信内用微信公众号支付，这样就少不了走公众号支付那一套，这里严重吐槽一下，

进入前页面后要判断是在微信内还是为微信外，微信内就要用

http://open.weixin.qq.com/connect/oauth2/authorize拿取授权码，因为公众号支付需要openId,而openId需要通过授权code获得，拿到授权code就可以调用jssdk支付了，在微信外走H5支付为调用接口生成预付单后微信会生成一个字段mweburl，这个是一个url，通过这个地址就可以唤起微信支付了，但是要传入refer如果你直接点击能想办法传过去也是可以的，我这里采用的方法是在页面内绑定点击事件，它传过去的时候就会解析到refer了，不传的话会报商家配置参数有误，

然后贴上html代码，供大家参考
