微信官方SDK在PHP7中提示：mcrypt_module_open() is deprecated，mcrypt已被OPENSSL代替
具体修改如下
1:WXBizDataCrypt.php
public function decryptData( $encryptedData, $iv, &$data )
{
if (strlen($this->sessionKey) != 24) {
return ErrorCode::$IllegalAesKey;
}
$aesKey=base64_decode($this->sessionKey);
if (strlen($iv) != 24) {
return ErrorCode::$IllegalIv;
}
$aesIV=base64_decode($iv);
// $aesCipher=base64_decode($encryptedData);
$aesCipher=$encryptedData;
$pc = new Prpcrypt($aesKey);
$result = $pc->decrypt($aesCipher,$aesIV);
var_dump($result);
if ($result[0] != 0) {
return $result[0];
}
$dataObj=json_decode( $result[1] );
if( $dataObj == NULL )
{
return ErrorCode::$IllegalBuffer.'--';
}
if( $dataObj->watermark->appid != $this->appid )
{
return ErrorCode::$IllegalBuffer.';;';
}
$data = $result[1];
return ErrorCode::$OK;
}
