如何在Django中处理POST请求中发送的excel文件？

from django.shortcuts import render
from openpyxl import load_workbook

def handle_excel(request):
    if request.method == 'POST':
        excel_file = request.FILES.get('excel_file')
        if excel_file.name.endswith('.xlsx'):
            try:
                workbook = load_workbook(excel_file)
                sheet = workbook.active
                for row in sheet.iter_rows():
                    for cell in row:
                        value = cell.value
                        # 处理每个单元格的值，可以存储到数据库或进行其他操作
                return render(request, 'success.html')
            except Exception as e:
                return render(request, 'error.html', {'error_message': str(e)})
        else:
            return render(request, 'error.html', {'error_message': '请上传Excel文件'})
    else:
        return render(request, 'upload.html')
