Uploading file to Anonfiles using anonfile module and FastAPI

Question

I am currently creating a website where the user sends the file and gets uploaded to anonfile website (I am using anofile python module). Before anonfile module, I was using mediafire module but it didn't work with video files so I moved to anonfile modul.

Here is the code:

app.py

from typing import List
import uvicorn
from fastapi import FastAPI, File, Request, UploadFile
from fastapi.templating import Jinja2Templates
from bs4 import BeautifulSoup
import requests
from anonfile import AnonFile

app = FastAPI()
templates = Jinja2Templates(directory="templates/")

def direct_link_anon(link):
  down_link1 = link
  r1 = requests.get(down_link1)
  soup1 = BeautifulSoup(r1.content, "html.parser")
  a_href1 = soup1.find("a", {"id": "download-url"}).get("href")
  a1 = str(a_href1)
  print(a1)
  return a1

@app.post("/")
async def create_upload_files(uploaded_files: list[UploadFile]):
    for files in uploaded_files:
        anon = AnonFile()
        upload = anon.upload(files.file)
        link = upload.url.geturl()
        result=direct_link_anon(link)
        download = "Download"
    return {'download': download,'result': result}


@app.get("/")
async def main(request: Request):
    return templates.TemplateResponse('index.html',context={'request': request})


uvicorn.run(app)

index.html

<html>
<head>
    <title>file upload</title>
    <script src="https://unpkg.com/dropzone@5/dist/min/dropzone.min.js"></script>
    <link rel="stylesheet" href="https://unpkg.com/dropzone@5/dist/min/dropzone.min.css" type="text/css" />
</head>
<body>
    <form action="/" class="dropzone" id="my-great-dropzone">
    </form>
    <a id="download-link" href=""></a>
    <script>
        Dropzone.options.myGreatDropzone = { // camelized version of the `id`
            paramName: "uploaded_files", // The name that will be used to transfer the file
            maxFilesize: 20000, // MB
            uploadMultiple: false,
            maxFiles: 1,
            maxFilesize: 1000000000,
            init: function() {
                this.on("maxfilesexceeded", function(file) {
                        this.removeAllFiles();
                        this.addFile(file);
                });
            } ,
            chunking: true,
            createImageThumbnails: true,
            success: function(file, response){
                var abc = response['result'];
                document.getElementById('download-link').innerHTML = '<a href="' + abc + '">Download</a>';
            }
        };
        
    </script>
</body>
</html>

The error:

files.file is not a directory

How can I solve this?

The package your are using to upload the file doesn't seem to support passing a file-like object (which is the result of calling the .file attribute of the UploadFile object). As can been in the source code here, the upload function instead accepts a path to the file in either str or Path format.

Hence, you can either save the file to a local directory on your disk and then pass the filepath to the upload function, as described in this answer and this answer, or save the file to a NamedTemporaryFile, which unlike SpooledTemporaryFile that UploadFile provides (using the .file attribute), "has a visible name in the file system"—which you can get using the .name attribute—and "can be used to open the file". Related answers with examples can be found here, here and here, as well as in this answer and this answer.
