我在這一天的好時間裏尋找解決方案，我仍然處於黑暗中。對於我的客戶，我創建了一個用於上傳圖片的簡單網絡圖庫，並使用valums file uploader。直到現在，我在我創建的任何其他站點上都沒有任何問題，除了我之前解決的miss-configuration問題。valums ajax-upload xhr.send（文件）後破壞的腳本 - 有時可以使用，有時不會
那麼，這是什麼問題？
當我上傳一個文件大小低於260KB的圖像時，它工作正常。但是，當我上傳更大的圖像時，它不會讓我回到任何錯誤。我只是得到一個空的縮略圖，因爲圖像沒有上傳。
當我打開瀏覽器控制檯，這是我所看到的：
POST http://designflowstudio.com/gallery2/include/upload.php?url=uploads%2Fe558c4dfc2a0f0d60f5ebff474c97ffc&fid=7&qqfile=316267269718409738080100.jpg 403 (Forbidden) fileuploader.js:1463 POST http://designflowstudio.com/gallery2/include/upload.php?url=uploads%2Fe558c4dfc2a0f0d60f5ebff474c97ffc&fid=7&qqfile=3.jpg 403 (Forbidden) fileuploader.js:1463
在某些情況下我得到413錯誤「請求實體太大」。
讓我說，這個問題真的讓我很懊惱，因爲腳本在我的本地web服務器（apache）和我的web服務器上運行良好。在這裏，我可以上傳儘可能大的圖片，但我可以在客戶端的網絡服務器上...
如果有人有時間和意願來幫助我，這裏是我用來調用valums上傳器的JavaScript ：
function createUploader(){
var uploader = new qq.FileUploaderBasic({

onProgress: function(id, fName, loaded, total){
var p = 0;
p = parseFloat(loaded/total*100);
if(isNaN(p)) p = '';
$('.progress'+id).progressbar("option","value",p);
},
onComplete: function(id,fName,json){
if(json.error){
$('#upload-list-'+id).html(fName+'<br />'+json.error);
}else{
$('#upload-list-'+id)
.attr("rel",json.fname)
.html('<img class="cmd" id="deleteImg" rel="'+json.id+'" src="<?php echo$home;?>images/delete.png" title="Delete picture" /><img class="img" src="<?php echo$home;?>uploads/<?php echo$g['path'];?>/th_'+json.fname+'" /><input class="ut" type="text" name="name" value="'+json.name+'" /><input class="ud" type="text" name="desc" /><div class="cl"></div>')
.attr("id",json.id);
}
},
onError: function(id,fName,error){
console.log(id+' '+fName+' '+error);
}
});
}
window.onload = createUploader;

讓我再說一遍，所有的呼叫到MySQL，文件與要求（）是有效的。這些腳本可以在另外兩臺服務器上運行，但是在這一臺服務器上，不是
謝謝你的時間和意願。
嗯，我知道了。 腳本_fileuploader.js_將內容類型設置爲_application/octet-stream_。到目前爲止，所有服務器都很好，但不是這個。當我評論它設置此內容類型的部分時，這開始發揮作用。 我評論部分： 'xhr.setRequestHeader（「內容類型」，「應用/八位字節流」）;' 同時，我認爲存在對服務器的mod_security啓用和腐化POST數據。 我發佈這個，希望有一天有人可能需要這些信息。因爲我經常在SO尋找幫助。 乾杯:) –
