Packet package is the prepay_id parameter value returned by Stringprepay_id=wx2017033010242291fcfe0db70013231072 unified order issuing API. Submission format such as: prepay_id=wx2017033010242291fcfe0db70013231072 signature method signType is StringMD5 signature type, default is MD5, and HMAC-SHA256 and MD5 are supported. Note that it needs to be consistent with the signature type of the unified order.

Examples are as follows:

PaySign = MD5 (appId=wxd678efh667hg6787&nonceStr=5K8264ILTKCH16CQ2502SI8ZNMTM67VS&package=prepay_id=wx2017033010242291fcfe0db70013231072&signType=MD5&timeStamp=1490840662&key=qazwsxedcrfvtgbyhnujmikolp111111) = 22D9B4E54AB1950F51E0649E8810ACD6
