我写了一个脚本,将从相机拍摄的图像上传到我的服务器.我得到200OK响应,但我没有在上传/文件夹中看到我的服务器上的图像：
也许我的脚本包含错误.请问你能帮帮我吗 ？
我的例子是以下链接：http://androidexample.com/Upload_File_To_Server_-_Android_Example/index.php?view=article_discription&aid=83&aaid=106

这是PHP脚本：
<?PHP $file_path = "uploads/"; $file_path = $file_path . basename( $_FILES['uploaded_file']['name']); if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'],$file_path)) { echo "success"; } else{ echo "fail"; } ?>
解决方法
您是否验证过用户apache(或者正在运行的用户PHP)是否有权写入$file_path中指定的目录？
将以下代码放在与PHP脚本相同的目录中,然后在Web浏览器中访问它.
<?PHP $file_path = 'uploads/'; $success = file_put_contents($file_path . "afile","This is a test"); if($success === false) { echo "Couldn't write file"; } else { echo "Wrote $success bytes"; } ?>
这会给出成功消息还是错误消息？
如果它给出错误消息,请尝试更改uploads目录的所有权.
