生成python-烧瓶服务器存根时没有定义模型对象。
生成python-烧瓶服务器存根时没有定义模型对象。

更新:我发现了这个问题。我在定义中对对象使用"File“一词似乎导致了这个问题。我将对象重命名为"FileThing“作为测试，swagger-codegen生成了预期的模型对象和模块。(也许这与https://github.com/swagger-api/swagger-codegen/issues/3223有关)。
当使用swagger-codegen从OpenAPI v2规范生成Python (Connexion)服务器存根时，我在生成的源代码中没有看到任何模型对象。但是，其他语言/API目标(如go-server )确实生成模型对象。我用的是swagger-codegen-cli-2.3.1.jar。在这一点上，我的规范非常简单，并且是：
swagger: "2.0"
info:
version: 0.0.1
title: Blah API
description: An API for interacting with the blah system
paths:
/files:
get:
description: Retrieves information on files that match the specified criteria
produces:
- "application/json"
parameters:
- name: tags
type: array
description: The tags for which matching files are to be returned
in: query
items:
type: string
responses:
'200':
description: Successful response
schema:
type: array
items:
$ref: "#/definitions/File"
definitions:
File:
type: object
properties:
file_id:
type: "string"
format: "uuid"
path:
type: "string"
tags:
type: array
items:
type: "string"如您所见，我希望看到为定义部分中定义的File对象创建的模型对象。但是，Source/swagger_server下的模型包仅包含一个base_model.py模块，除了基模型类本身之外没有其他定义。我运行swagger-codegen-cli，如下所示：

它看起来就像python-烧瓶生成器中的一个bug，它不生成与特定File类名(如Date、Set等)匹配的模型。这里通过importMapping在DefaultCodegen类中配置了“忽略模型”行为：
一些生成器(如C# )清除importMapping，因为它们不使用Java类映射：
importMapping.clear();但是python-烧瓶生成器并不能做到这一点。它可能也会清除importMapping，但我不是Python/Flask，所以我不确定。
我建议您在Swagger存储库中使用公开问题，并/或提交一个PR。
与此同时，一些可能的解决办法是：
- 将模型重命名，例如将其命名为
FileDTO。 - 创建自定义生成器基于python-烧瓶，添加
importMapping.clear()，并使用自定义生成器。
