上周做了个支付宝微信扫码支付，今天总结一下。微信相比支付宝要麻烦许多
由于涉及到代理商，没办法，让我写个详细的申请流程，懵逼啊。
先梳理下流程，对应的文档
要实现微信支付需要四个参数(需要企业认证，就不说了)
-
商户平台
- 商户号ID，也就是商户号。
- KEY，也就是API秘钥。
-
公众平台
- AppID
- AppSecret
梳理完之后，开始操作吧
第一步：参数准备和环境配置
上面的四大参数只有商户key相对比较麻烦
商户平台
公众平台
四大参数准备齐以及环境配置好开始第二步了。
第二步：开发流程
必须的参数有
- appid APPID （已有）
- mch_id 商户ID （已有）
- nonce_str 随机字符串
- sign 签名
- body 所支付的名称
- out_trade_no 咱们自己所提供的订单号,需要唯一
- total_fee 支付金额
- spbill_create_ip IP地址
- notify_url 回调地址
- trade_type 支付类型
- openid 支付人的微信公众号对应的唯一标识
官方就是官方，看着就是费劲，大白话听着多爽
陈海洋：
- 需要codeid，文档地址 https://qydev.weixin.qq.com/wiki/index.php?title=OAuth%E9%AA%8C%E8%AF%81%E6%8E%A5%E5%8F%A3 。
- 根据codeid来获取openid
- 根据openid来获取prepare_id
- 进行下单操作。js调起微信支付
操作1，用户授权获取code
https://open.weixin.qq.com/connect/oauth2/authorize?appid=APPID&redirect_uri=REDIRECT_URI&response_type=code&scope=SCOPE&state=STATE#wechat_redirect
注意点 redirect_url需要经过encodeURI编码。
可以使用 js内置的函数encodeURIComponent('http://www.baidu.com')来进行编码操作
我第一反应在想，为什么需要进行url编码，因为这个redirect_uri是作为参数来传递的。
之后就会重定向到你设置的url上面，并且携带code参数，我的后台是这么接收的
ok，code获取完毕
操作2，get请求接口对返回的string进行json解析获取到openid
操作3，post请求发送xml数据返回xml数据，通过官方下载的工具类实现xml转map获取预支付id
操作4，封装jsapi需要的
在微信浏览器里面打开H5网页中执行JS调起支付。接口输入输出数据格式为JSON。
ok，到此结束，微信支付成功调起。
需要注意的地方。
微信回调到时候会携带xml数据，这个时候并不能用参数接收，而应该是使用流来接收。
贴出完整代码，记录下
