本文介绍如何使用Flask和Django框架实现CSV文件的下载功能。通过具体代码示例，展示了设置响应头和内容类型的方法，以便客户端能够正确处理文件下载请求。

Only difference is make_response and httpresponse.

FLASK VERSION:

from flask import make_response

@app.route('/jobstatus_download/')
def jobstatus_download():
    with open('Job_status.csv', 'w') as f:
        writer = csv.writer(f)
        for row in sysdb_connection():
            writer.writerow(row)
    with open('Job_status.csv') as f:
        c = f.read()
    response = make_response(c)
    response.headers['Content-Type'] = 'application/octet-stream'
    response.headers['Content-Disposition'] = 'attachment;filename="{0}"'.format('Job_status.csv')
    return response

Django Version:

from django.http import HttpResponse
def snooper_download(request):
    with open('snooper_impact.csv', 'w') as f:
        writer = csv.writer(f)
        for row in cursor.fetchall():
            writer.writerow(row)
    with open('snooper_impact.csv') as f:
        c = f.read()
    response = HttpResponse(c)
    response['Content-Type'] = 'application/octet-stream'
    response['Content-Disposition'] = 'attachment;filename="{0}"'.format('snooper_impact.csv')
    return response
