PHP 文件下载有 ajax 个问题
PHP File Download with ajax Problems
我的问题是无法从服务器下载图像到我的电脑(没有保存提示),没有显示错误消息
我收到的输出是一些来自 google chrome 检查元素
的不可读代码
提前致谢
Javascript
function Download(id) {
console.log(id);
$.ajax({
type: 'post',
url: 'DownloadRequest.php',
data: {filename: id.trim()},
});
}
DownloadRequest.php 文件
<?php
$file = $_POST['filename'];
header ("Content-Type: application/download");
header ("Content-Disposition: attachment; filename=$file");
header("Content-Length: " . filesize("$file"));
$fp = fopen("$file", "r");
fpassthru($fp);
?>
解决方案
function Download(id) {
window.location="DownloadRequest.php?url="+id.trim();
}
<?php
$file = $_GET['url'];;
header ("Content-Type: application/download");
header ("Content-Disposition: attachment; filename=$file");
header("Content-Length: " . filesize("$file"));
$fp = fopen("$file", "r");
fpassthru($fp);
?>
你可以这样尝试,而不是使用ajax,
window.location="DownloadRequest.php?filename";
最终代码,
function Download(id) {
console.log(id);
window.location="DownloadRequest.php?filename";
}
