If there is no bill on that day, the XML will be returned as follows

<xml>
    <return_code></return_code>
    <return_msg></return_msg>
</xml>

2. Bill Into the database

The above bill data is a string, and it is only one day's data, which is not conducive to statistics and query. It also needs to be downloaded to the database.

1. Create a table

The bill fields include these

交易时间,公众账号ID,商户号,子商户号,设备号,微信订单号,商户订单号,用户标识,交易类型,交易状态,付款银行,货币种类,总金额,代金券或立减优惠金额,微信退款单号,商户退款单号,退款金额, 代金券或立减优惠退款金额，退款类型，退款状态,商品名称,商户数据包,手续费,费率

According to the above fields, create a table as follows

CREATE TABLE IF NOT EXISTS `wx_bill` (
  `id` int(10) NOT NULL AUTO_INCREMENT,
  `tradetime` varchar(20) NOT NULL,
  `ghid` varchar(20) NOT NULL,
  `mchid` varchar(20) NOT NULL,
  `submch` varchar(10) NOT NULL,
  `deviceid` varchar(16) NOT NULL,
  `wxorder` varchar(30) NOT NULL,
  `bzorder` varchar(30) NOT NULL,
  `openid` varchar(30) NOT NULL,
  `tradetype` varchar(10) NOT NULL,
  `tradestatus` varchar(10) NOT NULL,
  `bank` varchar(16) NOT NULL,
  `currency` varchar(20) NOT NULL,
  `totalmoney` varchar(20) NOT NULL,
  `redpacketmoney` varchar(20) NOT NULL,
  `wxrefund` varchar(10) NOT NULL,
  `bzrefund` varchar(10) NOT NULL,
  `refundmoney` varchar(20) NOT NULL,
  `redpacketrefund` varchar(20) NOT NULL,
  `refundtype` varchar(10) NOT NULL,
  `refundstatus` varchar(10) NOT NULL,
  `productname` varchar(30) NOT NULL,
  `bzdatapacket` varchar(10) NOT NULL,
  `fee` varchar(10) NOT NULL,
  `rate` varchar(10) NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `wxorder` (`wxorder`),
  UNIQUE KEY `bzorder` (`bzorder`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=272 ;

2. Into the database

Insert the WeChat bill data into the database and implement it as follows

  INSERT INTO `wx_bill` (`id`, `tradetime`, `ghid`, `mchid`, `submch`, `deviceid`, `wxorder`, `bzorder`, `openid`, `tradetype`, `tradestatus`, `bank`, `currency`, `totalmoney`, `redpacketmoney`, `wxrefund`, `bzrefund`, `refundmoney`, `redpacketrefund`, `refundtype`, `refundstatus`, `productname`, `bzdatapacket`, `fee`, `rate`) VALUES

2. Statistical analysis

With local data, various statistical analyzes can be performed.

1. Condition combination

The following is an interface implementation for combined query billing. You need to query the device used, the payment type used, and the specified time range.

The query results are as follows
