使用boto3和Django (以及S3)上传具有相同文件名的不同文件

import boto3
from django.core.files.storage import default_storage

def upload_file(request):
    file = request.FILES['file']
    file_name = file.name

    # Check if file with same name already exists
    if default_storage.exists(file_name):
        # Generate a unique file name
        unique_file_name = generate_unique_file_name(file_name)
        file_name = unique_file_name

    # Upload file to S3
    s3_client = boto3.client('s3')
    s3_client.upload_fileobj(file, 'your-s3-bucket', file_name)

    # Save file name or other relevant information in the database
    save_file_info_to_database(file_name)

    # Return response or redirect to another page
    return HttpResponse('File uploaded successfully')

def generate_unique_file_name(file_name):
    # Generate a unique file name based on your requirements
    # For example, you can append a UUID to the original file name
    unique_file_name = f"{file_name}-{uuid.uuid4()}"
    return unique_file_name

def save_file_info_to_database(file_name):
    # Save file name or other relevant information in the database
    # For example, you can create a File model and save the file name
    file = File(name=file_name)
    file.save()
