我確實有以下頁面中的一個正在做拖放和另一個獲取文件寫入。如果拖放在本地進行，則在遠程情況下不會出現問題。php和javascript不能發佈文件到遠程服務器，而發佈到本地服務器的工作

我的問題是，當我說明我目前的服務器：
var uploadURL ="http://192.168.56.153/WEBAPP/upload.php"
它的工作，這一點：
chmod -R 0777 /var/www/html/WEBAPP/
這僅僅是爲了測試（獲得的權利問題車程） ，我從apache訪問日誌中得到本地服務器的響應：
192.168.56.1 - - [08/Apr/2017:14:07:44 +0200] "POST /WEBAPP/upload.php HTTP/1.1" 200 203 "http://192.168.56.153/WEBAPP/demo_upload.php" "Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko"
我的文件正在上傳。
但是，當我改變了這個目的地遠程：
var uploadURL ="http://192.168.56.154/WEBAPP/upload.php"
我在遠程服務器Apache訪問日誌此消息：
192.168.56.1 - - [08/Apr/2017:13:44:13 +0200] "OPTIONS /WEBAPP/upload.php HTTP/1.1" 200 203 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko"
沒有文件上傳。
的upload.php的文件是相同的兩種情況：
<?php
$ds = DIRECTORY_SEPARATOR; //1
$storeFolder = 'uploads'; //2
if (!empty($_FILES)) {
$tempFile = $_FILES['file']['tmp_name']; //3
$targetPath = dirname(__FILE__) . $ds. $storeFolder . $ds; //4
$targetFile = $targetPath. $_FILES['file']['name']; //5
move_uploaded_file($tempFile,$targetFile); //6
}
?>

好吧...所以我必須添加這樣的內容：contentType：「text/plain」？但如果我想要照片？ – MouIdri
