是否可以将Slack通道配置为公共但只读为所有通道,例如Jenkins用户可以在其中写入消息？

(道歉,如果它是SO的主题)

我有一个UINavigationController提供的工具栏视图.

当我处理UIKeyboardWillShowNotification时,我将整个屏幕向上滚动键盘的高度.问题是当键盘显示时,底部工具栏没有,所以我需要向上滚动屏幕(keyboard.height - toolbar.height).

但是如何获得工具栏的高度？

谢谢

比方说,我有一个嘲弄的对象Car porsche.它有4个轮子,1个挡风玻璃,1个发动机和名称保时捷.这是通过when()和完成的thenReturn().

我想创建另一个模拟的Car实例,比如trabant,它将(再次when()和thenReturn())完全像保时捷实例一样,只返回一个不同的名称.

是否有可能创建没有重复所有基于一日一第二模拟when()和thenReturn()步骤？

我正在使用Linux Mint并尝试使用IntelliJ.

IntelliJ有一个Alt+ F1快捷键(选择...).不幸的是,Mint也使用它来显示工作空间的概述.

我想保留IntelliJ的快捷方式,并在Mint中禁用它.

我在哪里可以在Mint中禁用此Alt+ F1？我无法在键盘快捷键中看到它.

通过关注有关客户端凭证授予的 MS 信息，我获得了 JWT 令牌：

当我简单地将其复制粘贴到jwt.io时，令牌已正确解码，但其签名验证失败。所以我怀疑 jwt.io 无法正常工作，并想自己验证令牌。

令牌的标头：

{
  "typ": "JWT",
  "nonce": "pNYMBVFJpP1V2uU1ZRs5WsN-Xrx8c_8VZ59ElaLVAx0",

我想在Django应用中定期运行一个后端任务，并找到django-background-tasks（https://pypi.python.org/pypi/django-background-tasks）。

在页面之后，我

• pip安装包
• 将其添加到INSTALLED_APPS
• 创建了一个用@background（schedule = 5）注释的测试方法

但是，一旦调用该方法，就会得到“ django.db.utils.OperationalError：没有这样的表：background_task”

运行python manage.py migrate只能告诉我“没有要应用的迁移”（数据库具有用于其他已注册Django应用的表）。

django-background-tasks软件包是否不完整？如何为其创建数据库对象？
