利用nginx解決cookie跨域訪問的方法

更新時間：2018年05月11日 14:25:33 作者：孤王就是朕

本篇文章主要介紹了利用nginx解決cookie跨域訪問的方法，小編覺得挺不錯的，現(xiàn)在分享給大家，也給大家做個參考。一起跟隨小編過來看看吧

一、寫在前面

最近需要把阿里云上的四臺服務(wù)器的項目遷移到客戶提供的新的項目中，原來的四臺服務(wù)器中用到了一級域名和二級域名。比如aaa.abc.com 和bbb.abc.com 和ccc.abc.com。其中aaa.abc.com登錄，通過把cookie中的信息setDomain給.abc.com。其他系統(tǒng)可以共享這個cookie。但是新的四臺服務(wù)器中并沒有申請域名，只有四個ip:

192.168.0.1 單點登錄服務(wù)器

192.168.0.2

192.168.0.3

192.168.0.4

因為每臺服務(wù)器有兩個項目，都用到單點登錄，所以通過修改新的共享登錄方式花費時間太多，于是在網(wǎng)上搜cookie的跨域登錄，嘗試了下，在192.168.0.1 單點登錄服務(wù)器中多次setDomain分別給2、3、4服務(wù)器，結(jié)果不理想，因為瀏覽器不允許。后來無意中看到nginx可以通過欺騙的方式共享cookie。于是想到原來公司部署nginx還有這層用法。

二、原來的nginx配置

先說下nginx的安裝，這個網(wǎng)上都有很多教程，不在贅述，我是參照于在Linux里安裝、啟動nginx。需要注意的是./configure后面的各種with，我在配置啟動過程遇到了一些問題:

nginx: [emerg] unknown directive "aio" in

加上--with-file-aio

復(fù)制代碼代碼如下:

Starting nginx: nginx: [emerg] the INET6 sockets are not supported on this platform in “[::]:80” of the

在后面加上--with-ipv6好使。

安裝完成后。主要是nginx.conf的配置

原來服務(wù)器的配置nginx.conf：

# For more information on configuration, see:

user root;
worker_processes 2;

events {
  worker_connections 2048;
}

http {
  log_format main '$remote_addr - $remote_user [$time_local] "$request" '
           '$status $body_bytes_sent "$http_referer" '
           '"$http_user_agent" "$http_x_forwarded_for"';

  connection_pool_size 512;
  aio on;
  open_file_cache max=1000 inactive=20s;

  # Load modular configuration files from the /etc/nginx/conf.d directory.
  # See http://nginx.org/en/docs/ngx_core_module.html#include
  # for more information.
　　#　　主要配置在這里，nginx.conf配置都是一樣
  include /usr/local/nginx/conf/conf.d/*.conf;

  server {
    listen    80 default_server;
    listen [::]:80 ipv6only=on default_server;
    server_name _;
    root     html;

    # Load configuration files for the default server block.
    include /usr/local/nginx/conf/default.d/*.conf;

    location / {
    }

    error_page 404 /404.html;
      location = /40x.html {
    }

    error_page 500 502 503 504 /50x.html;
      location = /50x.html {
    }
  }
}

原來服務(wù)器的
conf.d/*.conf的配置是reverse-proxy.conf

server
{
  listen 80;
  server_name m.abc.com.cn;
  location / {
    root  /usr/share/nginx/html/;
    index index.html index.htm;
  }
  location ~ \.(jsp|do)?$ {
    proxy_redirect off;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://localhost:8084;
  }
  if ($http_user_agent ~* "qihoobot|Baiduspider|Googlebot|Googlebot-Mobile|Googlebot-Image|Mediapartners-Google|Adsbot-Google|Feedfetcher-Google|Yahoo! Slurp|Yahoo! Slurp China|YoudaoBot|Sosospider|Sogou spider|Sogou web spider|MSNBot|ia_archiver|Tomato Bot") { 
        return 403; 
    }
  access_log /home/logs/nginx/m.abc.com.cn_access.log;
}
 
server
{
  listen 80;
  server_name store.abc.com.cn *.store.abc.com.cn;
  location / {
    proxy_redirect off;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://localhost:8081;
  }
  access_log /home/logs/nginx/store.abc.com.cn_access.log;
}

server
{
  listen 80;
  server_name shopcenter.abc.com.cn;
  location / {
    proxy_redirect off;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://10.45.100.222:8082;
  }
  access_log /home/logs/nginx/shopcenter.abc.com.cn_access.log;
}
 
server
{
  listen 80;
  server_name search.abc.com.cn;
  location / {
    proxy_redirect off;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://10.45.100.68:8083;
  }
  access_log /home/logs/nginx/search.abc.com.cn_access.log;
}

以上配置后，nginx啟動后，通過訪問不同的域名來訪問不同服務(wù)器。而因為都有二級域名.abc.com.cn。所以可以共享cookie。

nginx的文件結(jié)構(gòu)為：

三、修改后的nginx配置

主要是reverse-proxy.conf 不同

server
{
  listen 9998;
  server_name 192.168.0.1:9998;
  location /servlets/ {
    proxy_redirect off;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://192.168.0.1:8088;
  }
  location / {

    root  /usr/local/nginx/html/web/;
    index index.html index.htm;
  }
  location ~ \.(jsp|do)?$ {
    proxy_redirect off;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://192.168.0.1:8088;
    
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_read_timeout  700s;
  } 
if ($http_user_agent ~* "qihoobot|Baiduspider|Googlebot|Googlebot-Mobile|Googlebot-Image|Mediapartners-Google|Adsbot-Google|Feedfetcher-Google|Yahoo! Slurp|Yahoo! Slurp China|YoudaoBot|Sosospider|Sogou spider|Sogou web spider|MSNBot|ia_archiver|Tomato Bot") { 
        return 403; 
    }
  access_log /usr/local/nginx/logs/www.abc.com.cn_access.log;
}

server
{
  listen 9994;
  server_name 192.168.0.1:9994;
  location / {
   proxy_redirect off;

    root  /usr/local/nginx/html/weixin/;
    index index.html index.htm;
  }
  location ~ \.(jsp|do)?$ {
    proxy_redirect off;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://localhost:8084;
  }
  if ($http_user_agent ~* "qihoobot|Baiduspider|Googlebot|Googlebot-Mobile|Googlebot-Image|Mediapartners-Google|Adsbot-Google|Feedfetcher-Google|Yahoo! Slurp|Yahoo! Slurp China|YoudaoBot|Sosospider|Sogou spider|Sogou web spider|MSNBot|ia_archiver|Tomato Bot") { 
        return 403; 
    }
  access_log /usr/local/nginx/logs/m.abc.com.cn_access.log;
}
 
server
{
  listen 9990;
  server_name store.abc.com.cn *.store.abc.com.cn;
  location / {
    proxy_redirect off;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://localhost:8081;
  }
  access_log /usr/local/nginx/logs/store.abc.com.cn_access.log;
}

server
{
  listen 9992;
  server_name 192.168.0.1:9992;
  location / {
    proxy_redirect off;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://192.168.0.2:8082;
  }
  access_log /usr/local/nginx/logs/shopcenter.abc.com.cn_access.log;
}
 
server
{
  listen 9993;
  server_name 192.168.0.1:9993;
  location / {
    proxy_redirect off;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://192.168.0.3:8083;
  }
  access_log /usr/local/nginx/logs/search.abc.com.cn_access.log;
}

這樣就可以把192.168.0.1:9998 當(dāng)做單點服務(wù)器，登錄后的domain都為192.168.0.1 。其他的0.2、0.3都可以通過192.168.0.1nginx和單點服務(wù)器的不同端口訪問，那么就可以共享這個0.1的域名了。

四、最后

好吧，可能描述的不是那么清楚，有點亂。我所做的工作就是把原來的nginx配置中的端口和域名改成新服務(wù)器中的唯一一個ip把這個ip當(dāng)做那個域名，不同端口對應(yīng)不同二級域名。
