我遇到了一个稍微困难的问题：1.发送带有POST数据的Ajax请求，让服务器生成一个ZIP文件；2.获得响应；3.下载ZIP文件
所以我就是这样做的(使用JQuery来处理Ajax请求)：初步员额请求：var parameters = {
pid : "mypid",
"files[]": ["file1.jpg","file2.jpg","file3.jpg"]}
var options = {
url: "request/url",//replace with your request url
type: "POST",//replace with your request type
data: parameters,//see above
context: document.body,//replace with your contex
success: function(data){
if (data) {
if (data.path) {
//Create an hidden iframe, with the 'src' attribute set to the created ZIP file.
var dlif = $('',{'src':data.path}).hide();
//Append the iFrame to the context
this.append(dlif);
} else if (data.error) {
alert(data.error);
} else {
alert('Something went wrong');
}
}}};$.ajax(options);
“requesturl”处理zip创建(OFF主题，所以我不会发布完整的代码)并返回以下JSON对象。类似于：//Code to create the zip file
//......
//Id of the file
$zipid = "myzipfile.zip"
//Download Link - it can be prettier
$dlink = 'http://'.$_SERVER["SERVER_NAME"].'/request/download&file='.$zipid;
//JSON response to be handled on the client side
$result = '{"success":1,"path":"'.$dlink.'","error":null}';
header('Content-type: application/json;');
echo $result;
如果需要，“请求/下载”可以执行一些安全检查，并生成文件传输：$fn = $_GET['file'];if ($fn) {
//Perform security checks
//.....check user session/role/whatever
$result = $_SERVER['DOCUMENT_ROOT'].'/path/to/file/'.$fn;
if (file_exists($result)) {
header('Content-Description: File Transfer');
header('Content-Type: application/force-download');
header('Content-Disposition: attachment; filename='.basename($result));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($result));
ob_clean();
flush();
readfile($result);
@unlink($result);
}}
