我有一个在 Flask/Connexion 上运行的 API。API 是用 OpenAPI 3 为 Swagger 编写的。我通过 multipart/form-data 将数据发送到端点，除了上传的文件之外，一切都通过了。我将从分享我的 OpenAPI YAML 文件开始。对于我引用的有关如何指定架构的文档的文件。

openapi: "3.0.0"

# Paths supported by the server application
paths:
   /api/submit:
    post:
      summary: Process a new text submission asynchronously
      operationId: submit.submit
      requestBody:
        content:
          multipart/form-data:
            schema:
              x-body-name: submission
              $ref: '#/components/schemas/Submission'
      responses:
        '200':
          description: That's nice

components:
  schemas:
    Submission:
      type: object
      required:
        - url
        - mimeType
        - language
        - content
      properties:
        url:
          type: string
          format: uri
        mimeType:
          type: string
          description: MIME type of the file submission
        language:
          type: string
          pattern: '^[a-z]{3}$'
        content:
          type: array
          items:
            type: string
            format: binary

submit.submit操作调用以下 Python 代码：

from datetime import datetime
import uuid

def get_timestamp():
    return datetime.now().strftime(("%Y-%m-%d %H:%M:%S"))

def submit(submission):
    print(str(submission))

    return { "timestamp": get_timestamp(), "uuid": str(uuid.uuid4()) }

Python 打印的是：

{'url': 'http://nosite.none', 'mimeType': 'text/plain', 'language': 'eng'}

所以不存在“内容”。但我知道数据正在发送，因为我在浏览器中将其捕获到出站：

-----------------------------138508216052
Content-Disposition: form-data; name="url"

http://nosite.none
-----------------------------138508216052
Content-Disposition: form-data; name="mimeType"

text/plain
-----------------------------138508216052
Content-Disposition: form-data; name="language"

eng
-----------------------------138508216052
Content-Disposition: form-data; name="content"; filename="nonsense.txt"
Content-Type: text/plain

Now is the time for
all good men to come
to the aid of their
party.
-----------------------------138508216052--

我应该对 Connexion 进行额外的调试，它会告诉我是否/为什么它没有传递“内容”文件？
