【问题描述】：
这是我的 android 客户端代码，它将文件从 android 库发送到 php 服务器：
package com.example.upload;

}
private void uploadImage() {

// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();

}
}
这是我的 PHP 代码：
<?php
$target_path = "uploadedimages/";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path))
{
echo "The file ". basename( $_FILES['uploadedfile']['name']).
" has been uploaded";
}
else
{
echo "There was an error uploading the file, please try again!";
}
?>
我正在尝试将图像从我的 android 客户端上传到 php 服务器。服务器响应消息给了我好的。服务器状态码也给出 200。因此，正在建立一个有效的 http 连接。尽管如此，图像文件并没有上传到我的域中。 Logcat 也不会记录任何错误。我很困惑我哪里出错了。任何帮助将不胜感激。

这是一个真实的网址
http://vijetakarani.com/upload.php？！如果是这样，请将其从您的问题中删除，否则您将被黑客入侵...... -
不客气，您应该限制 php.ini 中允许的文件类型。 stackoverflow.com/questions/7322137/…
