引用多個預定義的swagger 2.0參數定義拋出錯誤

Question

我在swagger 2.0文件中定義了兩個可重復使用的參數：

parameters:
  cursorParam:
    name: cursor
    in: query
    description: Pagination cursor.
    required: false
    type: string       
  limitParam:
    name: limit
    in: query
    description: Result limiter.
    required: false
    type: integer 

然后在我的路由定義（在本例中為GET）中，我試圖像這樣引用兩者：

parameters:
    - $ref: '#/parameters/cursorParam'
    - $ref: '#/parameters/limitParam'  

如果我使用一個$ ref，它似乎可以正常工作（沒有編譯錯誤），但是如果我嘗試同時使用兩個，則它會凝視我：

Operation parameter already defined: undefined
at paths ▹ /users ▹ get ▹ parameters ▹ 1 ▹ name

Operation parameter already defined: undefined
at paths ▹ /authorisations ▹ get ▹ parameters ▹ 1 ▹ name

此外，如果我在查詢字符串中傳遞這些參數並輸出req.swagger.params ， req.swagger.params得到一個空對象。 我究竟做錯了什么？

這是規格的完整SSCCE，會產生相同的錯誤：

看來您使用的是舊版本的a127。 Swagger文檔的所有部分都缺乏參考支持，最近已修復，因此更新應解決此問題。
