作者：gushaolin
本文主要介绍了nginx常见内置变量$uri和$request_uri的使用,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧
这里介绍nginx常见内置变量$uri和$request_uri代表的值，首先先看nginx配置：
[root@CentOS7-2 conf.d]# cat /etc/nginx/conf.d/default.conf
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log /var/log/nginx/host.access.log main;
location / {
root /usr/share/nginx/html;
# index index.html index.htm;
index jiade.html index.html;
}
location /test {
root /usr/share/nginx/html;
index test.html;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
配置log形式和保存路径：
[root@CentOS7-2 nginx]# cat /etc/nginx/nginx.conf
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
#配置nginx使用epoll I/O模型
use epoll ;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$uri --- $request_uri -- $remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
include /etc/nginx/conf.d/*.conf;
}
关停nginx：nginx -s stop
启动nginx：nginx
分析过程：通过nginx日志来分析得出$uri和$request_uri值
[root@CentOS7-2 nginx]# tail -200f /var/log/nginx/access.log /test/test.html --- /test/ -- 192.168.128.1 - - [31/Dec/2019:08:54:43 +0800] "GET /test/ HTTP/1.1" 304 0 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko" "-" /favicon.ico --- /favicon.ico -- 192.168.128.1 - - [31/Dec/2019:08:57:16 +0800] "GET /favicon.ico HTTP/1.1" 404 555 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36" "-" /jiade.html --- / -- 192.168.128.1 - - [31/Dec/2019:08:57:18 +0800] "GET / HTTP/1.1" 200 6 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko" "-" /favicon.ico --- /favicon.ico -- 192.168.128.1 - - [31/Dec/2019:08:57:19 +0800] "GET /favicon.ico HTTP/1.1" 404 555 "-" "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; Trident/4.0)" "-" /res --- /res -- 192.168.128.1 - - [31/Dec/2019:08:58:34 +0800] "GET /res HTTP/1.1" 404 153 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko" "-" /favicon.ico --- /favicon.ico -- 192.168.128.1 - - [31/Dec/2019:08:58:34 +0800] "GET /favicon.ico HTTP/1.1" 404 555 "-" "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; Trident/4.0)" "-" /jiade.html --- / -- 192.168.128.1 - - [31/Dec/2019:09:02:09 +0800] "GET / HTTP/1.1" 200 6 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko" "-" /favicon.ico --- /favicon.ico -- 192.168.128.1 - - [31/Dec/2019:09:02:09 +0800] "GET /favicon.ico HTTP/1.1" 404 555 "-" "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; Trident/4.0)" "-"
案例1：
访问：http://192.168.128.137/test/
$uri：/test/test.html
$request_uri：/test/
案例2：
访问：http://192.168.128.137/
$uri：/jiade.html
$request_uri：/
案例3（真实名字服务器上不存在res目录）：
访问：http://192.168.128.137/res
$uri：/res
$request_uri：/res
从上面三个案例就可以得出$uri和$request_uri所代表的值。
