微信公众平台

(此处只讲pay)

微信商户平台,公众号的后台管理工具,包含公众号的商户信息,公众号支付,扫码支付,刷卡支付

1.商户信息包含商户号,和此公众平台关联的商户号,需登录商户平台设置商户秘钥key

2.公众号支付包含支付授权目录,测试白名单(作用于微信Web开发者工具测试),扫码支付回调URL,刷卡支付

3.公众平台基本配置中查看本公众号的AppId,支付时使用

微信商户平台

微信商户平台,微信支付的后台管理工具,包含流水,订单,数据中心，账户中心

1.每个公众号对应一个商户平台,商户平台有自己秘钥key,支付中使用

2.APP支付的微信开放平台也对应一个商户平台,APP支付的key需使用此商户平台的

微信开放平台

微信开放平台,移动端使用的平台,APP支付需创建此平台,创建移动应用

1.创建此平台,审核移动应用,通过后会发邮件,其中包含商户账户信息,APP支付需使用

2.开放平台使用自己的AppId,和对应商户的key，切记

3.App支付和公众号的支付使用的AppId和key都不相同

微信公众号支付

JsApi支付

1.调用支付接口,判断订单号是否正确

App支付

App支付就简单多了，只需要统一下单接口,传给APP端,发起调用就ok

App回调支付和JsApi的一样，不做诠释
