How to create downloadable link to text file?
提问by u775856
The purpose is to download the dumped backup.sqlfile after running the sql dumping script (from PHP). Normally, the dumped .sqlfile is outputted (written) on the server. Then when i make a href link to that file like <a href="backup.sql">Download File</a>, the file is opening inside the browser on clicking, instead of being downloading.
目的是backup.sql在运行sql转储脚本（来自PHP）后下载转储文件。通常，转储的.sql文件在服务器上输出（写入）。然后，当我创建指向该文件的 href 链接时<a href="backup.sql">Download File</a>，该文件将在单击时在浏览器中打开，而不是正在下载。
- i just want to make a simple HREF LINK(to such a text file) which show up with "Save as.." dialog on simple Left Click.
- 我只想制作一个简单的HREF 链接（到这样的文本文件），在简单的左键单击上显示“另存为..”对话框。

Another option is serving it with in a .php file eg download.php
另一种选择是在 .php 文件中提供它，例如 download.php
have this in download.php
在download.php中有这个
$path = "backup.sql"
header("Content-Type: application/octet-stream"); //
header("Content-Length: " . filesize($path));
header('Content-Disposition: attachment; filename='.$path);
readfile($path);
then
然后
<a href="download.php">Download File</a>

If you have all export data (your .sql text e.g.) available on client, you could just
如果您有客户端上可用的所有导出数据（例如您的 .sql 文本），您可以
const blob = new Blob([fileContent], { type: 'text/plain' });
const a = document.createElement('a');
a.setAttribute('download', fileName);
a.setAttribute('href', window.URL.createObjectURL(blob));
a.click();
