当前 Bug 的表现（可附上截图）
预期表现
复现路径
提供一个最简复现 Demo
配置面单打印员,调用updatePrinter
传入参数access_token
传入参数openid
传入参数update_type
返回：
{“errcode”:44002,“errmsg”:“empty post data hint: [DAVJYa05498622]”}
并不是errcode 的合法返回值！
这该如何解决呢？
POST https://api.weixin.qq.com/cgi-bin/express/business/order/add?access_token=ACCESS_TOKEN
这个后端php执行这个请求，json数据都提交了，运单号没有生成，充的物流单数却减少了！！！！
重点是：这个单数是花钱从物流公司买的.
为了测试后台生成运单的功能，白白浪费了好几个，
问：
这个请求，在什么情况下扣除物流单数？
物流助手工具都拉取不到生成的运单，怎么能减少呢？？？
