php - 将 zip 文件上传到 PHP 上传站点不起作用，但适用于 mac

我有两个完全相同的文件。 Test.zip，两者大小相同。该文件是在我的 Mac 上创建的，可以很好地与我的上传脚本一起使用。我在我的 Windows 机器上制作了第二个 Test.zip 并尝试上传，但没有。

这是为什么？

所有文件类型都在索引和上传中正确列出，并且没有文件大小。我可以从我的 mac 上传 zip 文件，而不是我的 XP 机器。我可以从 Windows 上传除 rar/zip 之外的所有其他格式。

index.html 类型

   acceptedTypes = {
      'image/png': true,
      'image/jpeg': true,
      'image/gif': true,
      'application/x-rar-compressed': true,
      'application/zip': true,
      'application/octet-stream': true
    },

index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <style>
        .hidden {
            display: none;
            }
        #holder {
            margin-bottom: 20px;
            border: 10px dashed #ccc;
            min-height: 300px;
            width: 300px;
            }
        #holder.hover {
            border-color: #0c0;

上传.php

<?php

$temp = explode(".", $_FILES["file"]["name"]);
$extension = end($temp);
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/jpg")
|| ($_FILES["file"]["type"] == "image/pjpeg")
|| ($_FILES["file"]["type"] == "image/x-png")
|| ($_FILES["file"]["type"] == "application/x-rar-compressed")
|| ($_FILES["file"]["type"] == "application/octet-stream")
|| ($_FILES["file"]["type"] == "application/zip")
|| ($_FILES["file"]["type"] == "image/png"))

&& in_array($extension, $allowedExts))
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
    }
  else
    {
    echo "Upload: " . $_FILES["file"]["name"] . "<br>";
    echo "Type: " . $_FILES["file"]["type"] . "<br>";
    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
    echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>";

    if (file_exists("upload/" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
      }
    else
      {
      move_uploaded_file($_FILES["file"]["tmp_name"],
      "upload/" . $_FILES["file"]["name"]);
      echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
      }
    }
  }
else
  {
  echo "Invalid file";
  }
?>

最佳答案

上传 Windows 压缩 ZIP 时，$_FILES["file"]["type"] 的值是多少？可能是 mimetype 问题。当其他理智的世界使用 application/octet-stream 时，Microsoft 倾向于使用 application/octet。

一般来说，最好做一个变量转储发布来调试这样的事情。建议将它放在 upload.php 的顶部附近，以查看实际传递的内容:

echo '<pre>';
print_r($_FILES);
echo '</pre>';
