您需要使用
body参数：
"parameters": [ { "in": "body", "name": "body", "description": "Pet object that needs to be added to the store", "required": false, "schema": { "$ref": "#/definitions/Pet" } } ],并
#/definitions/Pet定义为模型：
"Pet": { "required": [ "name", "photoUrls" ], "properties": { "id": { "type": "integer", "format": "int64" }, "category": { "$ref": "#/definitions/Category" }, "name": { "type": "string", "example": "doggie" }, "photoUrls": { "type": "array", "xml": { "name": "photoUrl", "wrapped": true }, "items": { "type": "string" } }, "tags": { "type": "array", "xml": { "name": "tag", "wrapped": true }, "items": { "$ref": "#/definitions/Tag" } }, "status": { "type": "string", "description": "pet status in the store", "enum": [ "available", "pending", "sold" ] } }, "xml": { "name": "Pet" }},参考：https :
//github.com/OpenAPITools/openapi-generator/blob/master/modules/openapi-
generator/src/test/resources/2_0/petstore.json#L35-L43
OpenAPI / Swagger v2规范：https :
//github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md#parameter-
object
对于OpenAPI
v3规范，该
body参数已被弃用。要定义HTTP有效负载，需要使用HTTP有效负载
requestBody，例如https://github.com/OpenAPITools/openapi-
generator/blob/master/modules/openapi-
generator/src/test/resources/3_0/petstore.json#
L39-L41
OpenAPI v3规范：https：//github.com/OAI/OpenAPI-
Specification/blob/master/versions/3.0.0.md#requestBodyObject
