前言

SAP 银企直连，农业银行查询接口交易明细会生成固定格式的文本文件到前置机上面。
可以通过Http Get 方式下载。

提示：以下是本篇文章正文内容，下面案例可供参考

一、接口说明与核心代码

<?xml version="1.0" encoding="utf-8"?>
<ap>
  <CCTransCode>CQRA10</CCTransCode>
  <Corp>
    <StartDate>起始日期</StartDate>
    <EndDate>终止日期</EndDate>
  </Corp>
  <Channel>
    <LastJrnNo>0</LastJrnNo>
  </Channel>
  <Cmp>
    <DbAccNo>借方账号</DbAccNo>
    <DbProv>借方省市代码</DbProv>
    <DbCur>借方货币号</DbCur>
    <StartTime>末笔时间戳</StartTime>
  </Cmp>
</ap>

<?xml version="1.0" encoding="utf-8"?>
<ap>
  <Cme>
    <RecordNum>记录总数</RecordNum>
    <FieldNum>字段数</FieldNum>
  </Cme>
  <Cmp>
    <DbAccNo>借方账号</DbAccNo>
    <DbProv>借方省市代码</DbProv>
    <DbCur>借方货币号</DbCur>
    <BatchFileName>文件名</BatchFileName>
  </Cmp>
</ap>

下载文件：
账户明细文件信息 (文件名如上BatchFileName所示)
格式如下（MFS）：
