Create Image Upload is broken for Sync and Async

先从 Cloudflare 和 AsyncCloudflare 客户端的 images.v1.create 开始，然后检查 tests/api_resources/images/test_v1.py 中链接覆盖率附近的内容。使用为 WebP 文件展示的元组重现 multipart 上传，并在请求能够接受该上传且不再出现表单字段解析错误后，为同步和异步情况添加覆盖率。

Confirm this is a Python library issue and not an underlying Cloudflare API issue.

• This is an issue with the Python library

Describe the bug

The Cloudflare Image Create function is broken.

There is an example below, this has also been discussed on StackOverflow

https://stackoverflow.com/questions/79032782/error-5455-when-uploading-to-cloudflare-images-using-python-library

I cant see any test coverage for this use case.

https://github.com/cloudflare/cloudflare-python/blob/fc6ca90779cd230dc06445ba42e4c540da186ce0/tests/api_resources/images/test_v1.py#L28

To Reproduce

This is a working example using Python Requests

import requests
with open(
    "water bottle.webp", "rb"
) as f:
    data = f.read()

# try requests
files = {
    "file": (
        "water bottle.webp",
        data,
        "image/webp",
    )
}

response = requests.post(
    url=f"https://api.cloudflare.com/client/v4/accounts/{CLOUDFLARE_ACCOUNT_ID}/images/v1",
    headers={
        "Authorization": f"Bearer ..."
    },
    files=files,
)
print(response.status_code)
print(response.json())

This is a broken example using the Cloudflare Sync function

with open(
    "water bottle.webp", "rb"
) as f:
    data = f.read()

from cloudflare import Cloudflare

client = Cloudflare(
    api_token='...'
)

# Create a tuple: (filename, binary data, content type)
file_tuple = ("water bottle.webp", data,   "image/webp",)

cloudflare_image = await client.images.v1.create(
    account_id=CLOUDFLARE_ACCOUNT_ID,
    file=file_tuple,
)
print(cloudflare_image)

The output is

cloudflare.BadRequestError: Error code: 400 - {'result': None, 'success': False, 'errors': [{'code': 5400, 'message': 'Bad request: Error parsing form fields'}], 'messages': []}

This is a broken example using the Async Cloudflare function

from cloudflare import AsyncCloudflare

client = AsyncCloudflare(
    api_token='...'
)

# Create a tuple: (filename, binary data, content type)
file_tuple = ("water bottle.webp", data,   "image/webp",)

cloudflare_image = await client.images.v1.create(
    account_id=CLOUDFLARE_ACCOUNT_ID,
    file=file_tuple,
)
print(cloudflare_image)

The output is

cloudflare.BadRequestError: Error code: 400 - {'result': None, 'success': False, 'errors': [{'code': 5400, 'message': 'Bad request: Error parsing form fields'}], 'messages': []}
