java微信公众号JSAPI支付以及所遇到的坑

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。

笔记地址 http://note.youdao.com/noteshare?id=269ddffb1f95e69eafb281d054f9ff25&sub=82AACBC2E6814133938D407BD3FF4737

先梳理下流程，对应的文档

微信统一下单
H5页面调起微信支付
官方javademo

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

参考开发流程

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
