禅道开源版18.0迁移后企业微信通知失效问题

开源版18.0

我们进行了迁移，迁移的方法

1. 我们安装了相同版本的zbox

2. 恢复原禅道 上的数据，主要包含

    a、同步 /opt/zbox/app/zentao/www/data/upload/1 目录

    b、mysqldump 数据后，再导入

现在发现之前能用的企业微信通知现在失效，同时通过 【后台】 - 【通知】 - 【Webhook】，重新添加，无法绑定微信用户，如图

/opt/zbox/app/zentao/config/my.php中的debug 改成了 `true`后，能看到php开头日志有类似如下内容

```
