一、App平台支付流程
流程：支付平台功能申请 -> manifest.json 里配置支付参数 -> uni-app 里调用 API 进行支付
二、微信App支付功能申请
到 微信开放平台 申请移动应用并开通支付功能，申请应用后可以获取 AppID 和 AppSecret 值应用接入 微信商户平台，选择 App 支付开通支付功能后可获取支付业务服务器配置数据：PARTNER（财付通商户号）、PARTNER_KEY（财付通密钥）、PAYSIGNKEY（支付签名密钥）需要将从微信开放平台申请的appid，填回到 manifest-App SDK配置-支付-微信支付 中。打包后生效。

后台返回的微信订单参数：参照微信支付文档的统一下单参数进行对比
如在其过程中遇到：
uniapp APP端微信支付 签名错误，是因为uniapp调起微信支付需要进行第二次签名的，即根据后端统一下单返回数据再进行一次签名，签名方式要确保一致。详情请参照uniapp APP端微信支付 签名错误
