Use post to upload images and keys, request.body cannot get the value of the key

[cbc123]

Bug Description

Use post's multipart/form-data to upload images. The file in the body represents the image to be uploaded, the key, and the field data that the backend needs to get. The result is that request.body cannot get the key data, only the byte array of image data.

Steps to Reproduce

1. @api.post("/upload") async def file_upload(request:Request): """ 开始上传文件 :return: """ body = request.body

   print(body) byte_array = bytearray(body)

   将字节数组转换为图像

   image = Image.open(io.BytesIO(byte_array)) characters = string.ascii_letters + string.digits name = ''.join(secrets.choice(characters) for _ in range(10)) upload_dir = './admin/static/upload/' file_name = name+'.png' upload_dir = upload_dir+file_name

   image.save(upload_dir)

   image.show() return "success", {"Content-Type": "text/json"}

@cbc123 can I work on this??

[goSeeFuture]

I used python-multipart solved.

from multipart import parse_form

...
body = BytesIO(bytearray(request.body))

    def _on_filed(_field):
        pass

    def _on_file(_file):
        with open(_file.file_name, "wb") as f:
            f.write(_file.file_object.getbuffer())

    headers = {
        'Content-Type': request.headers.get("content-type"),
        'Content-Length': request.headers.get("content-length"),
    }
    parse_form(headers, body, on_field=_on_filed, on_file=_on_file)

    return {
        "status_code": 200,
        "type": "text",
    }

This has been implemented now and should be available in the latest releases
