我想要做的是指定有时对API调用的响应可能是PDF文档,有时它将是JSON。我想以OpenAPI 3.0格式执行此操作。对于PDF,响应将如下所示:
responses:
'200':
description: An invoice in PDF format.
content:
application/pdf:
schema:
type: string
format: binary
在JSON响应的情况下,这将描述响应:
responses:
'200':
description: A JSON object containing user name and avatar
content:
application/json:
schema:
$ref: "#/components/schemas/Invoice"
OAS3文档(https://swagger.io/docs/specification/describing-responses/)提供了以下示例,说明如何指定几个不同的JSON模式之一可能是对特定API调用的响应。这几乎是我想要的,除了不是描述不同的可能JSON模式,我想指定不同的可能内容类型,如上所述。有没有办法以OAS3格式执行此操作?
responses:
'200':
description: A JSON object containing pet information
content:
application/json:
schema:
oneOf:
- $ref: '#/components/schemas/Cat'
- $ref: '#/components/schemas/Dog'
- $ref: '#/components/schemas/Hamster'
答案 0 :(得分:2)
刚发现这有效:
responses:
'200':
description: "An invoice."
content:
application/json:
schema:
$ref: "#/components/schemas/Invoice"
application/pdf:
schema:
type: "string"
format: "binary"
