Flask 生成下载文件

1 后台程序直接生成文件内容

from flask import make_response

@app.route('/testdownload', methods=['GET'])

def testdownload():

    content = "long text"

    response = make_response(content)

    response.headers["Content-Disposition"] = "attachment; filename=myfilename.txt"

return response

 

2 读取一个服务器上的文件，供用户下载

from flask import make_response , send_file

@app.route('/testdownload', methods=['GET'])

def testdownload():

    response = make_response(send_file("views.py"))

    response.headers["Content-Disposition"] = "attachment; filename=views.py;"

return response
