如何让Swagger生成的Python客户端工作?

我已经从中生成了python客户端和服务器 https://editor.swagger.io/ -服务器运行正常,无需编辑,但我似乎无法让客户端与它通信,或者与任何东西通信。

我怀疑我在做一些非常愚蠢的事情,但我在互联网上找到的例子要么不起作用,要么似乎期望我了解如何制作对象。这是我的代码(我也尝试过不发送任何内容、字符串等):

import time
import swagger_client
import json
from swagger_client.rest import ApiException
from pprint import pprint

# Configure OAuth2 access token for authorization: petstore_auth
swagger_client.configuration.access_token = 'special-key'
# create an instance of the API class
api_instance = swagger_client.PetApi()
d = '{"id": 0,"category": {"id": 0,"name": "string"},"name": "doggie","photoUrls": ["string"],  "tags": [ {      "id": 0,      "name": "string"    }  ],  "status": "available"}'
python_d = json.loads(d)
print( json.dumps(python_d, sort_keys=True, indent=4) )
body = swagger_client.Pet(python_d) # Pet | Pet object that needs to be added to the store

try:
    # Add a new pet to the store
    api_instance.add_pet(body)
except ApiException as e:
    print("Exception when calling PetApi->add_pet: %s\n" % e)

我正在使用python 3.6.4,当运行上述命令时,我得到:

Traceback (most recent call last):
  File "petstore.py", line 14, in <module>
    body = swagger_client.Pet(python_d) # Pet | Pet object that needs to be added to the store
  File "/Users/bombcar/mef/petstore/python-client/swagger_client/models/pet.py", line 69, in __init__
    self.name = name
  File "/Users/bombcar/mef/petstore/python-client/swagger_client/models/pet.py", line 137, in name
    raise ValueError("Invalid value for `name`, must not be `None`")  # noqa: E501
ValueError: Invalid value for `name`, must not be `None`

我觉得我犯了一个难以置信的基本错误,但我实际上是从 https://editor.swagger.io/ -但由于我找不到一个实际可行的例子,我不知道我遗漏了什么。
