使用php和ajax从数据库下载文件

Python decorator as a staticmethod PYTHON 2021 - Delavaio

但是这种方式使用的是HTTP GET方法，参数只能通过URL参数方式传递，无法使用POST方式传递参数。. 于是，想到使用ajax方式下载文件。. 实验：ajax方式下载文件时无法触发浏览器打开保存文件对话框，也就无法将下载的文件保存到硬盘上！. 原因：ajax方式请求的数据只能存放在javascipt内存空间，可以通过javascript访问，但是无法保存到硬盘，因为javascript不能直接和硬盘交互 如何从数据库下载文件. I want to download file from my uploads table using the attribute sub_name, need help. I have this code of two PHP file one shows the files other downloads it but it's not working. The uplaods table include sub_name, upload_name, file_content (which is actually the uploaded file) . this way is easy ,but waiting for a long time. 2, upload this csv file using a php. then use ajax to record each row of the csv and output the ajax feedback.
