【问题描述】：

我正在尝试通过 Python 使用具有 OpenAPI 规范的 API。我生成了 openapi_client 并使用生成的示例之一开始。首次调用 API 成功，但后续调用因会话 ID 无效而失败。

  securitySchemes:
    user_session_authentication:
      description: [...]
      type: apiKey
      in: header
      name: SOME_PREFIX_user_session_id
security:
  - user_session_authentication: [] # default for all actions is user_session_id!

import openapi_client
from openapi_client.api import some_api
from openapi_client.model.inline_response200 import InlineResponse200
from openapi_client.model.inline_response2002 import InlineResponse2002
from pprint import pprint

with openapi_client.ApiClient() as api_client:
    username = "john"
    password = "45d75ii47"
    
    api_instance = some_api.SomeApi(api_client)
    username = username
    password = password
    body = function_a("foo")

    api_response = api_instance.foo(username=username, password=password, body=body)
    pprint(api_response)
    
    api_response = api_instance.bar()
    pprint(api_response)

对 foo() 的 http 响应包含键值对 'user_session_id': '1bf92fc3-7f2a-450f-a472-03a07a70bd8d'。如何将此键值对添加到第二个请求的标头中？目前，第二个请求的标头仅包含以下内容：{'Accept': 'application/json', 'User-Agent': 'OpenAPI-Generator/1.0.0/python'}

我找到了this 的问题并针对我的用例修改了代码：

import openapi_client
from openapi_client.api import some_api
from openapi_client import Configuration
from openapi_client.model.inline_response200 import InlineResponse200
from openapi_client.model.inline_response2002 import InlineResponse2002
from pprint import pprint

with openapi_client.ApiClient() as api_client:
    username = "john"
    password = "45d75ii47"
    
    api_instance = some_api.SomeApi(api_client)
    username = username
    password = password
    body = function_a("foo")

    api_response = api_instance.foo(username=username, password=password, body=body)
    pprint(api_response)
    
    conf = Configuration()
    conf.api_key = {"SOME_PREFIX_user_session_id": api_response.user_session_id}
    api_client = openapi_client.ApiClient(None, "SOME_PREFIX_user_session_id", conf.get_api_key_with_prefix("user_session_id"))
    api_instance = some_api.SomeApi(api_client)

    api_response = api_instance.bar()
    pprint(api_response)
