Nginx增添mime类型 修改mime type类型默认打开方式的方式

PHP实现图片上传程序（完整版）

Nginx的mime type

Nginx 会凭证mime type界说的对应关系来告诉浏览器若那边理服务器传给浏览器的这个文件，是打开照样下载；若是Web程序没设置，

Nginx也没对应文件的扩展名，就用Nginx 里默认的 default_type界说的处置方式。

php上传文件 $_FILES['']['type']的值
先来看一个函数:

好比Nginx默认的设置中default_type application/octet-stream; 这个就是默以为下载，浏览器接见到未界说的扩展名的时刻，就默以为下载

该文件；若是将这个设置改成default_type text/html；那就是告诉浏览器默认的打开方式是把所有未设置的扩展名当HTML文件打开

，虽然可能这样设置会许多打不开。

mime type 和文件扩展名的对应关系一样平常放在 mime.types这个文件里，然后用 include mime.types; 来加载

mime.types文件里是用types指令来界说的，下面是一个完整的界说：

types {

一样平常在Nginx的设置文件nginx.conf内里的http{}字段中设置即可，注重mime.types是在你的nginx的安装目录下，若是目录不是下面的，那你要自己手工修改：

# Define the MIME types for files.
include /etc/nginx/mime.types;
default_type application/octet-stream;
# Update charset_types due to updated mime.types
charset_types text/xml text/plain text/vnd.wap.wml application/x-javascript application/rss+xml text/css application/javascript application/json;
