買粉絲紅包的技術原理是怎樣的

class Wxapi {

private $app_id = 'wxXXXXXXXXXXXX'; //公眾賬號appid，首先申請與之配套的公眾賬號

private $app_secret = 'XXXXXXXXXXXXXXXXXXXXXXXX';//買粉絲secret，用戶獲取用戶授權token

private $app_mchid = 'XXXXXXXX';//商戶號id

function __買粉絲nstruct(){

//do sth here....

}

例如：

appid： wxd111665abv58f4f

mch_id： 10000100

device_info： 1000

Body： test

nonce_str： ibuaiVcKdpRxkhJA

第一步：對參數按照 key=value 的格式，并按照參數名 ASCII 字典序排序如下：

stringA="appid=wxd930ea5d5a258f4f&body=test&device_info=1000&mch_i

d=10000100&nonce_str=ibuaiVcKdpRxkhJA";

第二步：拼接支付密鑰：

stringSignTemp="stringA&key=192006250b4c09247ec02edce69f6a2d"

sign=MD5(stringSignTemp).toUpperCase()

="9A0A8659F005D6984697E2CA0A9CF3B7"

*/

protected function get_sign(){

define('PARTNERKEY',"QSRXXXXXXXXXXXXXXXXXXXXX");

try {

if (null == PARTNERKEY || "" == PARTNERKEY ) {

throw new SDKRuntimeException("密鑰不能為空！" . "<br>");

}

if($this->check_sign_parameters() == false) { //檢查生成簽名參數

throw new SDKRuntimeException("生成簽名參數缺失！" . "<br>");

}

$買粉絲monUtil = new CommonUtil();

ksort($this->parameters);

$unSignParaString = $買粉絲monUtil->formatQueryParaMap($this->parameters, false);
