加密方式

请求参数 依次从a-z排列 然后拼接后加入加密app_secret 然后MD5加密 即可得到签名字符串

PHP示例

private static function generateSign($params, $appSecret)
    {
        ksort($params);
        $str = '';
        foreach ($params as $key => $value) {
            $str .= self::percentEncode($key). self::percentEncode($value);
        }
        $str .= $appSecret;
        return md5($str);
    }
    private static function percentEncode($str)
    {
        // 使用urlencode编码后，将"+","*","%7E"做替换即满足 API规定的编码规范
        $res = urlencode($str);
        $res = preg_replace('/\+/', '%20', $res);
        $res = preg_replace('/\*/', '%2A', $res);
        $res = preg_replace('/%7E/', '~', $res);
        return $res;
    }
