简易文件下载服务器
Great-Front实践之简易文件服务器
Author: Once Day Date: 2022年10月8日
人生在世，如同梦一场…
1.序言
收集了网上的一些其他大佬的代码和资料，整合了一个简单的文件服务器，聊胜于无吧。
不废话，直接开始正题。
2.下载软件
2.1 下载web服务器
web服务器使用nginx，轻量简单，而且免费，在官网下载即可：
- nginx: download
根据情况选择Windows或者Linux下载。
2.1 配置nginx服务器(windows)
这里只是最简单的文件服务器，而且目前仅用于下载，比较适用于局域网内部：
配置文件在nginx根目录下的.\conf\nginx.conf：
主要修改http里面内容：
http {
include mime.types;
default_type application/octet-stream;
sendfile on; #开启发送文件内容
keepalive_timeout 65;
server {
#配置监听端口
#可选的域名(外网可以映射到局域网)
#以及本地IP
listen 80;
server_name xxx.onceday.work;
server_name 172.20.35.46;
server_name localhost;
location /doc {
alias doc;
index index.html index.htm;
}
#下面就是文件所在的目录，最重要的是后面几行的内容
location /soft {
alias soft;
charset utf-8;
autoindex on;# 显示目录
autoindex_localtime on;# 显示文件时间
autoindex_exact_size off;# 显示文件大小
add_after_body /autoindex.html; #美化目录
}
location = /autoindex.html {
root html;
}
location /{
root html;
index main.html main.htm;
}
error_page 404 /404.html;
location = /404.html {
root html;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /html;
}
}
具体的location规则可以自行百度，这里就不赘述了。
autoindex.html是专门网上寻找的一个美化下载界面的java script代码。
2.2 个性化的404网页
下面是一个网上寻找的404美化界面，其实也可以拿来做其他界面：

效果如下：
结合了个人的一些理解，算不上多好，至少比nginx原生的要好看一些。
2.5 额外介绍页
通过ifame可以插入一个小框用来显示而外的介绍内容，而且不需要对框架过多的修改，只需要放置一个html文件即可。
if (my_html_name !== '') {
my_link = "http://172.20.35.46/"+my_html_name
my_title = div.add('a')
my_title.attr('class', 'my-link').attr('href', my_link).text('原文阅读')
my_frame = div.add('iframe')
my_frame.attr('src', my_link)
}
操作很简单，但很有用。
