⼆、⽣成⽀付⼆维码
public Map createNative(String orderNo){
try{
//1 根据订单号查询订单信息
QueryWrapper<Order> wrapper =new QueryWrapper<>();
wrapper.eq("order_no", orderNo);
Order order = One(wrapper);
//2 使⽤map设置⽣成⼆维码需要参数
Map m =new HashMap();
/
/1、设置⽀付参数
m.put("appid","wx74862e0dfcf6****");
m.put("mch_id","155895****");
m.put("nonce_str", ateNonceStr());
m.put("body", CourseTitle());
m.put("out_trade_no", orderNo);
m.put("total_fee", TotalFee().multiply(new BigDecimal("100")).longValue()+"");
m.put("spbill_create_ip","127.0.0.1");
m.put("notify_url","******/api/order/weixinPay/weixinNotify\n");
m.put("trade_type","NATIVE");
//3 发送httpclient请求传递参数xml格式⽀付提供固定的地址
HttpClient client =new HttpClient("h.weixin.qq/pay/unifiedorder");
//设置cml格式的参数
client.ateSignedXml(m,"T6m9iK73b0kn9g5v426MKfHQH7******")); client.setHttps(true);
//执⾏请求发送
client.post();
//4 得到发送请求的返回结果
//返回的内容是xml格式将xml转化为map
String content = Content();
//将xml转为map
Map<String, String> resultMap = lToMap(content);
//最终返回数据的封装
Map map =new HashMap<>();
map.put("out_trade_no", orderNo);
map.put("course_id", CourseId());
map.put("total_fee", TotalFee());
map.put("result_code", ("result_code"));
map.put("code_url", ("code_url"));
return map;
}catch(Exception e){
throw new GuliException(20001,"⽣成⼆维码失败");
}
}
三、查询⽀付状态
public Map<String, String>queryPayStatus(String orderNo){
try{
//1、封装参数
Map m =new HashMap<>();
m.put("appid","wx74862e0dfcf6****");
m.put("mch_id","155895****");
m.put("out_trade_no", orderNo);
m.put("nonce_str", ateNonceStr());
//2、设置请求
HttpClient client =new HttpClient("h.weixin.qq/pay/orderquery");
client.ateSignedXml(m,"T6m9iK73b0kn9g5v426MKfHQH7******")); client.setHttps(true);
client.post();
//3、返回第三⽅的数据
String xml = Content();
Map<String, String> resultMap = lToMap(xml);
//6、转成Map
//7、返回
return resultMap;
}catch(Exception e){
e.printStackTrace();
}
return null;
