我们正在使用 PLupload 将图像上传到亚马逊 S3 存储桶。但是我们需要为上传的文件设置缓存控制。
我尝试添加标题 {'cache-control':'155520000'}，并将其添加到 multipart_params 下。没运气。
以下是我们使用的代码。任何帮助将不胜感激。
$(function() {
$('#progressbar').hide();
var uploader = new plupload.Uploader({
init : {
FilesAdded: function(up, files) {
plupload.each(files, function(file) {
if (up.files.length > 1) {
up.removeFile(file);
}
});
},
},
preinit : {
UploadFile: function(up, file) {
var filenamevous;
if('thumb' in file){
up.settings.multipart_params.key = 'thumb_'+imagename;
}
else
{
up.settings.multipart_params.key = makeid()+'.jpg';
}
imagename = up.settings.multipart_params.key;
var filenamevous;
filenamevous = $("#txtImageTitle").val();
var category;
category = $("#category").val();
$.post("<?php echo $this->config->item('actionFeUrl'); ?>/pictures/ajax",{imname:imagename,oriname:filenamevous,catName:category,task:'uploadedimage'},function(data)
{
});
}
