Ios 将图像从iphone上载到服务器文件夹

我在网上发现了一些将图像从iphone上传到服务器文件夹的代码片段，它显示了如何使用服务器端脚本，例如在服务器端使用php

<?php
$uploaddir = 'uploads/';
$file = basename($_FILES['userfile']['name']);
$uploadfile = $uploaddir . $file;

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
        echo "Uploaded!";
}else{
   echo "Not Uploaded!";
}
/>

如果将Web服务器设置为允许PUT方法，则可以执行此操作。99%的web服务器只允许GET和POST方法

我从来没做过那件事，所以帮不了你多少忙。这是我从谷歌那里得到的一个关于它的页面：


此代码将对您有所帮助……
我必须删除带有应用程序/八位字节流的行，以使其与附件一起工作。知道为什么吗？这是很棒的代码。第一次为我工作。谢谢parvind:）请注意上传文件的大小。您在内存中创建整个文件内容的请求，然后发送它…如果文件太大（或者您同时上载了许多文件），您可能会面临内存消耗问题
