php和javascript不能发布文件到远程服务器，而发布到本地服务器的工作
问题描述：
我确实有以下页面中的一个正在做拖放和另一个获取文件写入。如果拖放在本地进行，则在远程情况下不会出现问题。php和javascript不能发布文件到远程服务器，而发布到本地服务器的工作

我的问题是，当我说明我目前的服务器：
var uploadURL ="http://192.168.56.153/WEBAPP/upload.php"
它的工作，这一点：
chmod -R 0777 /var/www/html/WEBAPP/
这仅仅是为了测试（获得的权利问题车程） ，我从apache访问日志中得到本地服务器的响应：
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"
我的文件正在上传。
但是，当我改变了这个目的地远程：
var uploadURL ="http://192.168.56.154/WEBAPP/upload.php"
我在远程服务器Apache访问日志此消息：
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"
没有文件上传。
的upload.php的文件是相同的两种情况：
<?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
}
?>

您获得，因为CORS的类型选项的请求。加载JavaScript脚本的域必须与请求的域相同。禁止跨境请求，这就是为什么他们经常被转换为OPTIONS请求。
但是，您可以通过设置响应标头Access-Control-Allow-Origin: *来允许跨域请求。详情请参阅HTTP access control (CORS)。
这是[CORS“预检请求”]（https://www.w3.org/TR/cors/#resource-preflight-requests）[相关问题]（http://stackoverflow.com/questions/ 1256593 /为什么我得到一个选项请求，而不是一个请求） – segFault
好吧...所以我必须添加这样的内容：contentType：“text/plain”？但如果我想要照片？ – MouIdri
