PHP文件上传不断抛出错误

Question

我正在将一个rsa私钥(.pem文件)上传到我的网站并使用fopen来读取内容,但最近我一遍又一遍地得到同样的错误而没有多大意义.

HTML

  <form enctype="multipart/form-data" action="upload.php" method="post">
    <input type="hidden" name="MAX_FILE_SIZE" value="1000000" />
    Choose a file to upload: <input name="uploaded_file" type="file" />
    <input type="submit" value="Upload" />
  </form> 

upload.php的

<?php
session_start();

if( $_SERVER['SERVER_PORT'] == 80) {
    header('Location:https://'.$_SERVER['HTTP_HOST'].$_SERVER["REQUEST_URI"]); 
    die();
} 



echo $_FILES['uploaded_file']['name'];

//?heck that we have a file
if((!empty($_FILES["uploaded_file"])) && ($_FILES['uploaded_file']['error'] == 0)) {
  $filename = basename($_FILES['uploaded_file']['name']);
  $ext = substr($filename, strrpos($filename, '.') + 1);
  if (($ext == "pem") && ($_FILES["uploaded_file"]["type"] == "text/plain")) {

$fh = fopen($_FILES['uploaded_file']['name'], 'r');

//continue with code
  } else {
     echo "Error: Only pem files are accepted for upload";
  }
} else {
 echo "Error: No file uploaded";
}
?>

该网站不断返回错误:

警告:fopen(mykey.pem)[function.fopen]:无法打开流:38号线上没有这样的文件或目录

(这是fopen行).它进入fopen状态的事实向我证明它确实上传但是使用fopen(也尝试使用file_get_contents($ _ FILES ['uploaded_file'] ['name']);以及失败)返回错误.

什么da puh!

最后的说明:

无论出于何种原因,fopen()不喜欢读取OpenSSL证书并返回错误:

openssl_private_decrypt():提供的资源不是有效的OpenSSL X.509 /密钥资源

如果你使用file_get_contents它会工作.

我相信你正试图打开一个错误的文件(名字).由于我在代码中的任何地方都没有看到move_uploaded_file(),您可能应该从$ _FILES数组中读取tmp_name而不是name:

$fh = fopen($_FILES['uploaded_file']['tmp_name'], 'r');
