摘要
由于新项目马上启动，看了下需求文档，其中，会用到ApplePay技术实现支付功能，于是，现做一些技术准备，把之前有学习ApplePay方面的知识做个总结，待真正开发时，应用上去。
1、证书创建
使用ApplePay开发，需要一个商户ID，开通权限，然后根据需求拼接支付请求。Apple Pay会对支付信息进行加密处理，以防止未获授权的第三方获取用户的支付信息。剩下的就是在自己的服务器上进行支付流程和处理了。苹果开发applyPay功能，是需要创建一个商业证书的，下面介绍创建方法:
-
获取证书

然后，点击上图中右上角的+号，如下图进入创建界面
applePay2.png
然后点击continue,最后点击register，这样就注册完一个商业id证书了。
点击刚刚的证书，进入编辑页面，选择YES，如下：

这时候，苹果会要你上传一个CSR文件，也就是从钥匙串->证书助理->从证书颁发机构请求证书所生成的证书，上传完成后，即可把商业
2、商户id创建
3、代码实现
-
添加商户id到环境配置中
