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);
AjaxResponse<Object> response = restTemplate.postForObject(reqUrl.toString(), null, AjaxResponse.class);
if (null == response || !response.isState()) {
throw new MsgException("获取开放平台Token出错！");
}
Map<String, Object> resMap = (Map<String, Object>) response.getData();
accessToken = (String) resMap.get("access_token");
// 设置token 过期时间（开放平台30分钟过期）
long expires_in = (Integer) resMap.get("expires_in") - 60;
redisUtil.set(redisKey, accessToken, expires_in);
return accessToken;
}
- 调用开票平台B 开票接口
/**
* 调用诺诺开票接口
* @param invoiceGuid 发票Guid
* @throws Exception
*/
@Override
@Transactional(rollbackFor = Exception.class)
public void openInvoice(String invoiceGuid, String centerGuid) throws Exception {
TfcInvoicePO invoicePO = dao.findByPrimaryKey(invoiceGuid);
AssertU.notNull(invoicePO, "查询发票信息出错");
//1、调用开票平台开票
String redisKey = StaticValue.OPEN_INVOICE_TOKEN_PREFIX + ":" + centerGuid;
String token = getOpenToken(redisKey);
//请求头参数
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON_UTF8);
headers.add("access_token", token);
//请求参数
Map<String, Object> params = buildInvoiceOrder(centerGuid, invoicePO);
HttpEntity<Object> httpEntity = new HttpEntity<>(params, headers);
//封装发票订单
String openUrl = url + OpenInvoiceConstant.OPEN_INVOICE_URL;
ResponseEntity<AjaxResponse> responseEntity = restTemplate.exchange(openUrl, HttpMethod.POST, httpEntity, AjaxResponse.class);
AssertU.notNull(responseEntity, "提交发票失败");
AjaxResponse<Object> response = responseEntity.getBody();
AssertU.isTrue(response.isState(), response.getMsg());
Map<String, Object> data = (Map<String, Object>) response.getData();
//2、调用第三方开票成功，将本地发票状态改为开票中
TfcInvoicePO updateInvoicePO = new TfcInvoicePO();
updateInvoicePO.setGuid(invoiceGuid);
updateInvoicePO.setStatus(InvoiceStatusEnum.INVOICING.getKey());
updateInvoicePO.setInvoiceWay(InvoiceWayEnum.ONLINE.getKey());
updateInvoicePO.setInvoiceSerialNo(String.valueOf(data.get("invoiceSerialNum")));
dao.update(updateInvoicePO, "guid");
}
- 封装订单信息 buildInvoiceOrder
private Map<String, Object> buildInvoiceOrder(String centerGuid, TfcInvoicePO invoicePO) throws Exception {
Map<String, Object> params = new HashMap<>();
params.put("buyerAccount", invoicePO.getAccountBank());

- 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；
