发票验真功能小结

 

1. 在项目中，如果需要将发票导入到发票行中，在导入前会有对增值税专用发票进行验真操作，一般调用公用的外围接口来实现验真发票的头行信息是否准确，是否一致，如果不一致，那么该发票就不允许使用。本项目主要通过HTTP请求来调用大象的发票验真接口，然后将返回的结果存入到表中。

 

2. 发票验真的三方地址最好能够配置，增强系统的可配置性:

3. 验真完后，需要校验发票的信息是否准确，可以通过本地接口再去查验，确保验真的信息是否与客户手上的信息是否一致。确保发票的完整性和准确性。

        在费用行，填单时，手工录入发票前端需要调一个三方接口去查验该发票信息，拿到接口返回的信息后，再在本地接口查验，查验完毕后，录入到票库中(invoice_head)，然后前端根据后端返回的查验字段(check_result)的值来判断是否查验成功。

 手工录入的先调用三方接口，然后再调用本地接口校验
 三方接口:
 Request URL: /api/invoice/check/query?roleType=TENANT
Request Method: POST
 
 本地接口校验 ，调用本地接口时，需要将三方接口的返回作为参数使用
 Request URL: /api/invoice/head/check/invoice?roleType=TENANT
Request Method: POST

另外如果票夹中已经存在，那么应该从票夹中导入,在票夹中经过校验的发票才能够被拿来使用:
