如何使用 busybox httpd 设置标头

我正在使用以下命令运行 busybox httpd：

busybox httpd -p 80 -h /var/www

它可以工作，但是我需要将缓存控制标头设置为无缓存。

目前我的服务器仅附加这些标题：

  HTTP/1.0 200 OK
  Content-type: text/html
  Date: Thu, 28 Jun 2018 06:58:08 GMT
  Connection: close
  Accept-Ranges: bytes
  Last-Modified: Thu, 28 Jun 2018 06:57:43 GMT
  Content-Length: 45

我如何配置我的busybox httpd服务器以附加

Cache-Control: no-cache

标题？

BusyBox HTTP Daemon (httpd) webserver 是一个自己的简单 web 服务器实现，没有广泛的配置选项，正如你从OpenWRT配置文档或来自的评论块httpd.c来源（第 39-60 行）：

 * httpd.conf has the following format:
 *
 * H:/serverroot     # define the server root. It will override -h
 * A:172.20.         # Allow address from 172.20.0.0/16
 * A:10.0.0.0/25     # Allow any address from 10.0.0.0-10.0.0.127
 * A:10.0.0.0/255.255.255.128  # Allow any address that previous set
 * A:127.0.0.1       # Allow local loopback connections
 * D:*               # Deny from other IP connections
 * E404:/path/e404.html # /path/e404.html is the 404 (not found) error page
 * I:index.html      # Show index.html when a directory is requested
 *
 * P:/url:[http://]hostname[:port]/new/path
 *                   # When /urlXXXXXX is requested, reverse proxy
 *                   # it to http://hostname[:port]/new/pathXXXXXX
 *
 * /cgi-bin:foo:bar  # Require user foo, pwd bar on urls starting with /cgi-bin/
 * /adm:admin:setup  # Require user admin, pwd setup on urls starting with /adm/
 * /adm:toor:PaSsWd  # or user toor, pwd PaSsWd on urls starting with /adm/
 * /adm:root:*       # or user root, pwd from /etc/passwd on urls starting with /adm/
 * /wiki:*:*         # or any user from /etc/passwd with according pwd on urls...
 * .au:audio/basic   # additional mime type for audio.au files
 * *.php:/path/php   # run xxx.php through an interpreter

使用 BusyBox HTTPd 的选项：

  • BusyBox HTTP Daemon 是开源的。修改httpd.c添加标题并进行编译。
  • 您的页面是否已作为CGI脚本。开头可以有自定义标题。

或者安装一些具有以下功能的更多功能的 Web 服务器：Nginx，阿帕奇，Lighttpd...

docker run -d --name busybox-http -p 8080:8080 -e TZ=UTC-8 busybox sh -c "
echo GMT-8 > /etc/TZ
mkdir -p /root/cgi-bin
cat > /root/cgi-bin/a.html <<EOF
#!/bin/sh
echo -e 'Content-Type: text/plain\n'
echo \"hostname=[\\\$(hostname)], time=[\\\$(date '+%F %T')], query=[\\\${QUERY_STRING}], path=[\\\${PATH_INFO}]\"
echo \"requestUrl=[\\\${REQUEST_URI}]\"
echo -e \"\n=== env list:\n\\\$(env|sed 's/\n/<br>/g')\"
EOF
chmod u+x /root/cgi-bin/a.html
httpd -p 8081 -h /root
cat > /root/httpd.conf <<EOF
P:/:http://localhost:8081/cgi-bin/a.html/
EOF
httpd -p 8080 -c /root/httpd.conf
sleep infinty
"

curl localhost:8080/a/b?c=1

结果输出：

hostname=[e95c54e5ff19], time=[2021-01-19 23:20:42], query=[c=1], path=[/a/b]
requestUrl=[/cgi-bin/a.html/a/b?c=1]
