下载本地文件就是找到文件路径  调用flask自带的send_file(路径)下载， 并返回

flask:

# 下载文件

from flask import send_file

@task_mgm.route('/taskinfo_download=<string:filename>')

@sso_wrapper

def taskinfo_download(filename):

UPLOAD_FOLDER = 'app/controls/task_mgm/task_files/'

ROOT_FOLDER = os.path.join(os.getcwd(), UPLOAD_FOLDER)  # 整合绝对路径

response = make_response(send_file(ROOT_FOLDER + filename))

return response

 

js:

 

// 下载文件 $("#download").click(function () {
       if(confirm('确定下载？')){ var filename = $('#download').val(); // $.get('/task_mgm/taskinfo_download='+filename) if(filename){ window.location.href='/task_mgm/taskinfo_download='+filename } else { alert('下载失败') } } });
