English version:
host, remote address, and method, the user is allowed to enter multiple different values, use space as separatorChinese version:
选项 A: 用户按需添加可选字段,对于不关心过滤条件,在界面上完全不显示
Option A: The user adds fields as needed. For the filter conditions that are not concerned, it is not displayed at all on the interface.

方案 B: 界面上告诉用户所有大的选项,用户手动点击右侧的 CheckBox 决定是否开启这个可选项。
Option B: The interface tells the user all the options, the user manually clicks on the CheckBox on the right to decide whether to enable this option.

only uri is required, host,remote_addr and methods are optional.
plan B is the fast way to choose conditions.
I would prefer Plan A from UX side.
均允许用户输入多个不同的值,空格分割
ElementUI has provided a good component to implement the requirement above.

I think the plan A is simpler and easier to understand.
选项A 更合适,(必选)的界面适合所有人,隐藏的选项(界面)适合于高端玩家,高端玩家会自行探索 "+"后的奥秘
Please take a look at the new Dashboard.
