Php 有没有办法告诉浏览器禁用；“运行”；下载EXE时的按钮？
对于某些无限带宽类型的用户来说，让他们不断下载您的产品并不断忘记将其放置在何处并重新下载，可能会很方便。但是，当保释金担保人用两米长的麻袋把本周的捕获物装进验尸官的时候，他对验尸官说，对资金短缺的认识是智慧的开始，我想省去我们的麻烦 下面是我在PHP中所做的Php 有没有办法告诉浏览器禁用；“运行”；下载EXE时的按钮？,php,download,mime-types,content-disposition,Php,Download,Mime Types,Content Disposition,对于某些无限带宽类型的用户来说，让他们不断下载您的产品并不断忘记将其放置在何处并重新下载，可能会很方便。但是，当保释金担保人用两米长的麻袋把本周的捕获物装进验尸官的时候，他对验尸官说，对资金短缺的认识是智慧的开始，我想省去我们的麻烦 下面是我在PHP中所做的 header("MIME-Version: 1.0"); header("Pragma: public"); header("Expires: 0"); header("Cache-Control: post-check=0, pre-ch

我能补充一句话吗？这句话会神奇地把所有浏览器弄糊涂，让他们认为任何操作系统都不可能对这一块字节做任何事情，除非把它放在某个安全的位置，让它的主人在空闲时摆弄它 据我所知，没有。文件下载由浏览器处理，并提供其认为合适的选项。你可以用Java或Flash定制应用程序来实现这一点，但我不是100%赞同，因为当浏览器提示下载时，它仍然可能胜过该应用程序
或者，您可以让用户通过匿名FTP帐户下载文件，但这需要用户了解如何使用FTP客户端，并且需要在他们的计算机上安装FTP客户端，才能不显示弹出对话框 据我所知，没有。文件下载由浏览器处理，并提供其认为合适的选项。你可以用Java或Flash定制应用程序来实现这一点，但我不是100%赞同，因为当浏览器提示下载时，它仍然可能胜过该应用程序
或者，您可以让用户通过匿名FTP帐户下载文件，但这需要用户了解如何使用FTP客户端，并且需要在他们的计算机上安装FTP客户端，才能不显示弹出对话框 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的下载次数。另一种选择可能是将.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。如果您还没有安装，您也可以使用安装程序，并将应用程序配置为无法从浏览器“运行”，但必须正确安装。这样，图标/开始菜单项就可以供下次使用。如果它们有用户帐户，一个解决方案就是简单地限制每个帐户允许的下载次数。另一种选择可能是将.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。如果您还没有安装，您也可以使用安装程序，并将应用程序配置为无法从浏览器“运行”，但必须正确安装。这样，图标/开始菜单项就可以供下次使用。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打开，等等 看看这个：
