增值税发票识别API开发文档、发票ocr
2、调用客户端运行环境
当客户端使用的编程语言为Java时，请使用1.5及以上版本JRE。
3、服务主要功能描述
发票识别服务，支持增值税发票识别、火车票识别、机动车销售统一发票识别、PDF电子发票识别（仅支持PDF格式识别）、定额发票识别、出租车发票识别、航空运输电子客票行程单识别，并支持自动分类。识别速度快，支持扫描件识别和拍照识别。
1) 通过https协议post方法上传各种发票图像文件，通过https接口进行识别；
2) 将识别结果以XML或json格式返回给用户；
4、服务调用约束
在调用发票识别接口前，请您确保客户端程序或设备网络连接通畅，要求图像文件大小在200KB左右，扫描图像建议分辨率为300DPI，图像小于3M。
二、前提准备
1、用户登录 注册账号
- 输入注册信息，确认无误后点击同意条款并注册
3、注册成功后点击右上角的账号名称-个人中心，进入管理页面
（注：调用图片为base64流接口时传参数img，调用图片为file格式接口传参数file）
接口调用方法：post

调用方式(java客户端基于httpclient4.3)
1.依赖库: \java客户端\httpClient4.3库\
2.示例程序代码详见: \java客户端\httpClientDemo\中的Client类
在main方法定义参数，并传入 doPost(url, file, key, secret, typeId,outvalue, format)方法中。
执行main方法返回识别结果如下：
