"rtf"在使用"finfo"执行MIME/扩展名验证脚本的过程中，文件扩展名消失了. PHP类 [英] The "rtf" file extension is disappearing during the execution of the mime/extension validation script using "finfo" PHP class

问题描述

我正在尝试使用"extension X mime"文件值通过phpmailer创建上传文件的交叉验证，系统正在处理几乎所有需要执行此操作的文件，但是与.rtf文件不同的是，脚本是工作.

I am trying to create a cross validation of uploaded files through phpmailer using the "extension X mime" file values, the system is working to almost all files that i need to do this, but exceptionally with .rtf files the script isn't working.

扩展名消失了，如果文件为.rtf，则脚本无法获取该扩展名.我正在使用此脚本: https://stackoverflow.com/a/33349901/4623271 进行了一些修改.

The extension just disappear, the script can't get this if the file is .rtf. I'm using this script: https://stackoverflow.com/a/33349901/4623271 with some adaptations.

是变量$ext，在其中我可以获取验证允许的任何文件的扩展名，除了.rtf文件，当文件为.rtf时，该变量显然为空.

Bellow in the code, is the variable $ext where i can get the extension of any files allowed by the verification, except .rtf files, when the file is a .rtf, the variable becomes apparently empty.

我尝试使用$ext = end(explode(".", $_FILES["uploadedFile"]["name"]));，但是以相同的方式，当.rtf文件为时，变量变为空.

I tried using $ext = end(explode(".", $_FILES["uploadedFile"]["name"])); but in the same way, when is a .rtf file, the variable becomes empty.

    // mime verification
    $finfo = new finfo(FILEINFO_MIME_TYPE);
    if (false === $ext = array_search(
        $finfo->file($_FILES['uploadedFile']['tmp_name']),
        array(
            'doc' => 'application/msword',
            'docx'  => 'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
            'rtf' => 'application/msword',
            'odt' => 'application/vnd.oasis.opendocument.text',
            'txt' => 'text/plain',
            'pdf' => 'application/pdf',
        ),
        true
    )) {
         $errorMsg .= "<br> Please, watch that the formats allowed are: \"doc\", \"docx\", \"rtf\", \"odt\", \"txt\", \"pdf\"' ";
    }

谢谢您的宝贵时间.

推荐答案

我发现问题出在我在数组中用于验证.rtf文件的mime值中.

I have discovered that the problem is in mime value that i was using in array to validate the .rtf file.

$finfo = new finfo(FILEINFO_MIME_TYPE);读取的mime类型不是在联机表中找到的具有此类信息的常见mime类型，并且我已经使用它来创建初始数组.

The mime type readed by $finfo = new finfo(FILEINFO_MIME_TYPE); is not the usual mime type finded in online tables with this kind of information and that i have used to create the initial array.

在一个巴西PHP Telegram组中寻求帮助之后，我得到了提示提示，以分析$finfo变量的值.

After searching for help in a Brazilian PHP Telegram group, I received the hint to analyse the value of the $finfo variable.

当我应用var_dump ($finfo->file($_FILES['uploadedFile']['tmp_name']));时，我发现FILEINFO_MIME_TYPE文件的mime是FILEINFO_MIME_TYPE而不是application/rtf，这是我上面说的text/rtf而不是application/rtf，这是.rtf文件.

When i applied var_dump ($finfo->file($_FILES['uploadedFile']['tmp_name'])); I discovered that to FILEINFO_MIME_TYPE the mime of .rtf files is: text/rtf and not application/rtf, that as i said above, is the most common option of mime type to .rtf files.

因此，由于脚本期望text/rtf与.rtf文件相关联，因此发生了验证错误.

Because of this, the validation error was occurring since the script expected text/rtf to associate with .rtffile.

在更改text/rtf而不是application/msword或application/rtf的键值之后，脚本按预期工作.

After I change the key value for text/rtf instead application/mswordor application/rtf , the script worked as expected.

现在，我正在使用phpmailer发送带有mime验证的附件.

Now i´m sending attachments with mime validation using phpmailer.
