CodeIgniter：错误上传文件mime类型 [英] CodeIgniter: wrong uploading file mime type

问题描述

有时，当使用< input> 标记上传文件时，遇到问题，其中文件扩展名与 application / config / mimes.php 。例如，当我上传一个 .doc 文件时，事实证明它的MIME类型实际上是 application / octet-stream ，而不是 application / msword 。

Sometimes, when uploading files using <input> tag, I encounter problem where the file extension doesn't match with its mime type defined in application/config/mimes.php. For example when I upload a .doc file, it turns out that its mime type is actually application/octet-stream, not application/msword as expected.

我过去有这个问题。我通过添加 application / octet-stream 到 .doc mime数组。但是有正确的方法来修复它吗？

I had this problem sometimes in the past. I did work around by adding application/octet-stream to .doc mime array. But is there a proper way to fix it?

我认为浏览器强制我的文件的MIME类型不知何故。是否有任何种类的HTTP标头或HTML元标记来防止这种情况？

I think the browser have force my file's mime type somehow. Is there any kind of HTTP header or html meta tag to prevent this?
