What are the methods to force nginx to use https access?
nginx的rewrite方法
思路
这应该是大家最容易想到的方法，将所有的http请求通过rewrite重写到https上即可
配置
server {
listen 111:80;
server_name testcom;
rewrite ^(*)$ https://$host$1 permanent;
}搭建此虚拟主机完成后，就可以将http://test.com的请求全部重写到https://test.com上了
nginx的497状态码
error code 497
497 - normal request was sent to https
解释：当此虚拟站点只允许https访问时，当用http访问时nginx会报出497错误码
思路
利用error_page命令将497状态码的链接重定向到https://test.com这个域名上
配置
server {
listen 11:443; #ssl端口
listen 11:80; #用户习惯用http访问，加上80，后面通过497状态码让它自动跳到443端口
server_name testcom;
#为一个server{}开启ssl支持
ssl on;
#指定pem格式的证书文件
ssl_certificate /etc/nginx/testpem;
#指定pem格式的私钥文件
ssl_certificate_key /etc/nginx/testkey;
#让http请求重定向到https请求
error_page 497 https://$host$uri?$args;
}index.html刷新网页
思路
上述两种方法均会耗费服务器的资源，我们用curl访问baidu.com试一下，看百度的公司是如何实现baidu.com向www.baidu.com的跳转
可以看到百度很巧妙的利用meta的刷新作用，将baidu.com跳转到www.baidu.com.因此我们可以基于http://test.com的虚拟主机路径下也写一个index.html，内容就是http向https的跳转
index.html
<html> <meta http-equiv="refresh" content="0;url=https://testcom/"> </html>
nginx虚拟主机配置
server {
listen 11:80;
server_name testcom;
location / {
#indexhtml放在虚拟主机监听的根目录下
root /srv/www/httptestcom/;
}
#将404的页面重定向到https的首页
error_page 404 https://testcom/;
