上一篇文章搭建了开票中间平台B，下一步平台C调用开票平台B业务流程
一、开票系统调用流程
- 首先，调用平台C须提前注册到开票平台B，获取到对应的clientId，clientSecret。注册信息包括回要回调的地址callBackUrl（开票成功或失败回调使用）；
-
业务流程图如下
开票系统流程图.png - 调用平台C 获取token，缓存在redis中
/**
* 获取开放平台Token
* @return
*/
private String getOpenToken(String redisKey) {
String accessToken = (String) redisUtil.get(redisKey);
if (StringUtils.isNotBlank(accessToken)) {
return accessToken;
}
//获取token Url
StringBuilder reqUrl = new StringBuilder();
reqUrl.append(url + OpenInvoiceConstant.ACCESS_TOKEN_URL);
reqUrl.append("?client_id=").append(clientId);
reqUrl.append("&client_secret=").append(clientSecret);

- 开票平台B接收到C开票请求后，调用诺诺平台A开票接口，A回调B，B回调C，C更新开票单状态；
开票单状态4个，暂存，开票中，开票失败，开票完成；
开票前为暂存状态，提交开票请求后，状态会变成开票中，接收回调信息后，改变发票状态为开票失败或开票完成；
