二维码无法失效；之前有人测算过，即使全球几十亿人天天用，也得到时空俱灭的时候才能枚举完，订单失效就行了，无须再管二维码的“有效期”了

不是自动关闭，是无法唤醒支付，相当于票据失效

key.pem 是RSA私钥，错误提示应该指你没有提供 apiclient_cert.pem 文件，这个文件是「证书」你把这个也加上试试。

编码上 ^M = \r\n，一般经过HTTP传输都会被带上这个\r\n，建议还是检查一下自己的程序逻辑，解析XML/JSON时，同时忽略掉\r及或\n。

需要开通「免充值代金券」产品权限，之后才能上传券用图片素材。

tarType = GZIP, 你获取的stream是gzip流，需要先解压。。。

3、 用标准的RSA加密库对敏感信息进行加密，选择RSA_PKCS1_OAEP_PADDING填充模式       （eg：Java的填充方式要选 " RSA/ECB/OAEPWITHSHA-1ANDMGF1PADDING"） https://pay.weixin.qq.com/wiki/doc/api/tools/mch_pay_yhk.php?chapter=24_7
