对于大文件(>5MB)，使用HttpResponse下载文件时出现“正文太长”的抛出错误

from django.http import HttpResponse
from wsgiref.util import FileWrapper
import os

def download_large_file(request):
    file_path = '/path/to/your/file'  # 替换为实际文件路径

    if os.path.exists(file_path):
        file_name = os.path.basename(file_path)
        response = HttpResponse(FileWrapper(open(file_path, 'rb')), content_type='application/octet-stream')
        response['Content-Disposition'] = 'attachment; filename=' + file_name
        response['Content-Length'] = os.path.getsize(file_path)
        response['Transfer-Encoding'] = 'chunked'  # 设置chunked传输方式

        return response
    else:
        return HttpResponse('File not found.')
