1、首先找银行申请，按照他那边的规定把所有资料给到他，然后他会帮我们申请（我这次联系的是邮政的）
2、申请完成之后，商户后台的登录地址、账号、密码、开发者秘钥，会以邮箱形式发送我们的邮箱
3、进入商户后台做微信配置（搜不到的话找银行那边人对接，可能出现的问题很多，信息错一个都会导致匹配不上）。根据商户编号搜到之后进到配置页：
4、进到配置页后，先添加appid。注意：公众号主体一定要和银行那边开户主体一致，公司的一定做企业认证，在我们信息没有问题的前提下，配置不上找银行那边对接人员处理。
5、配置合法域名，和公众号的配置一样有，（vue的有一个问题，vue是单页面，前端跳转到支付页的时候记得使用<a></a>标签跳，不然合法域名的验证会不通过）
6、发起支付的时候可能会出现下图问题这个也是找银行那边做一个实名认证，步骤挺多的，申请完等审核通过就可以了。
