同样的数据只要这里面<detail></detail>内容减少就可以调用支付接口（https://api.mch.weixin.qq.com/pay/micropay）成功。而上面的内容较多但是并没有超过6000个字符，就报上面的那个错误了

你好，这个问题怎么解决的

付款码付款接口明明生效了,为什么返回值是: post数据为空 ?

/pay/micropay 付款码付款接口明明生效了,但是返回值 return_code 是 “FAIL”, return_msg 是 “post数据为空” 我微信这边已经收到输入支付密码的通知了,我输入了密码付款就成功了. 我把请求参数全部打印出来了,post数据根本就不是空,况且是只有用一个新付款码第一次付款就会出现这个情况,再次用这个付款码第二次付款就恢复正常了. 请问是怎么回事?这是不是微信支付的bug?
