Duplicate tags will not be filtered out

[caixingyue]

I have defined the same tag in different classes. It is recommended to keep only one tag to avoid duplication.

"tags": [ { "name": "Auth", "description": "认证" }, { "name": "Other", "description": "其它能力" }, { "name": "Auth", "description": "认证" }, { "name": "Auth", "description": "认证" } ]
