Python 3.x 由于'；没有名为'；错误

我正在使用OpenAPI 3.0.1 yaml，由于以下错误，它无法启动API Web服务器。我尝试了我所知道的几乎所有东西，但我对OpenAPI非常陌生，文档也照样做了。你有没有想过这里会出什么问题

这是加载服务器时出现的错误：

提前谢谢大家

操作ID必须与应用程序的运行位置相关

swagger_server
|-- app.py
|-- __init__.py
|-- OpenAPI
|   |-- openapi.yml
|-- models
|   |-- catalog.py

根据上述文件夹结构，您可以在目录swagger_服务器中启动应用程序。因此，

app.py

的路径在您的

sys.path

中。相对于此路径，您需要在

openapi.yml

中指定

操作ID

：

paths:
  /v2/catalog:
    get:
      tags:
      - Catalog
      summary: get the catalog of services that the service broker offers
      operationId: 'models.catalog.get'

---

文件catalog.py必须包含函数

def get（name）

。在这里，您可以定义端点的服务/处理程序。它必须包含参数

name

，因为您已在YAML文件中指定了该参数。

operationId:“catalog.get”

在Python术语中是指来自catalog import get的

。您是否有模块或软件包
目录
，可以从中导入name
get
？是的。在我的D:\API\swagger\u server\models中，我有一些模块，其中一个是catalog.py:#编码：utf-8从future导入绝对值#从datetime导入日期#datetime#noqa:F401从键入导入列表，Dict#noqa:F401从swagger\u server.models.base\u model#从swagger\u server.models.service导入服务#noqa:F401，E501来自swagger_服务器导入util类目录（型号）：“”“注意：这个类是由swagger代码生成器程序自动生成的…”。。。operationId必须与您运行应用程序的位置相关。例如，如果您的应用程序在目录swagger_服务器中运行，则需要在yml中指定“models.catalog.get”。谢谢，@高于\u c_级别。这可以解决这个问题。我现在有另一个问题：“AttributeError:module'models.catalog'没有属性'get'”，但我相信这是由swagger生成的代码出了问题，好像YAML指定了它，模块应该有get属性，对吗？也许'get'只是一个默认值。我认为Connexion定义了这样的默认值。但是，您只需打开catalog.py并查看是否有函数get（）。如果没有，你必须写一个。：）
paths:
  /v2/catalog:
    get:
      tags:
      - Catalog
      summary: get the catalog of services that the service broker offers
      operationId: 'models.catalog.get'
