有没有方法告诉浏览器在下载exe时禁用“运行”按钮?

content-disposition mime-types download php

    对于某些无限制的带宽类型来说,让您的用户不断下载您的产品,并不断忘记将其放在何处,然后重新下载可能比较方便。但是,正如保释担保人对验尸官说的那样,对缺乏证据的认知是智慧的开始,因为他用一个两米长的麻袋装了本周的捕获物,我想为我们省去麻烦。

    下面是我用PHP做的工作 

    header("MIME-Version: 1.0");
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: post-check=0, pre-check=0");
header("Content-type: application/octet-stream");
header('Content-Length: ' . $filesize);
header('Content-Disposition: attachment; filename="' . basename($filename).'"');
header("Content-Transfer-Encoding: binary");
readfile($filename);

    是否还有另一行我可以添加,这将神奇地混淆所有浏览器认为没有任何操作系统可以做任何事情,除了把它放在一个安全的位置,让它的主人在他或她的闲暇时间摆弄?

    据我所知,没有,没有。文件下载由浏览器处理,并根据需要提供选项。你 可以 可以用Java或Flash中的自定义应用程序来实现这一点,但我不是100%,因为当浏览器提示下载时,它仍可能胜过该应用程序。

    或者,您可以让用户通过匿名ftp帐户下载该文件,但这要求用户了解如何使用ftp客户机,并要求其计算机上的ftp客户机弹出对话框不显示。

    如果他们有用户帐户,一个解决方案就是简单地限制每个帐户允许下载的次数。另一个选项可能是将.exe粘贴到zip文件中,这样它就不能简单地“运行”…尽管浏览器可能会尝试以任何方式在临时文件中显示内容。如果还没有安装程序,也可以使用安装程序,并将应用程序配置为不能从浏览器“运行”,但必须正确安装。这样,图标/开始菜单条目就可以用于下一次使用。

    如果指定文件的mimetype,浏览器将显示它应该显示的内容。例如,PDF将提示在PDF查看器中打开或保存,图像将使用图像应用程序或另存为等打开。

    看看这个: 

    $info = pathinfo($fileName); 
header('Content-Description: File Transfer');
header('Content-Type: '.Mimetypes::get($info['extension']));
header('Content-Disposition: attachment; filename=' . basename($fileName));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($fileName));

class Mimetypes{
/**
*   static isAllowed returns true for allowed extensions and false otherwise.
*   method is static thus allowing is to be called without construction/
*   instantiation of the object.  
*
*   @param string ext the file extension 
*   @return boolean true for allowed extension, false otherwise 
*
*/
public static function isAllowed($ext){
    $allowedFiletypes = array('jpg','gif','bmp','png', 'xls', 'doc', 'docx', 'txt', 'pdf'); // These will be the types of file that will pass the validation.
    if(in_array($ext, $allowedFiletypes)){
        return true;    
    }else{
        return false;
    }
}//end isAllowed($ext) 

/**

*   and returns the mimetype for this given argument
