有時候我們想對響應(例如PHP介面)返回的內容做些字串,雖然可以使用各語言程式碼相關方法(例如PHP的str_replace
)進行替換,但是在nginx層面替換是更方便的,無需修改程式碼。
約定:本文原始碼目錄統一放在:/root/soft/src
裡。
安裝
安裝此模組需要先安裝 sregex
執行庫:
$ git clone https://github.com/agentzh/sregex
$ cd sregex
$ make
$ make install
然後安裝 replace-filter-nginx-module
模組:
$ cd /root/soft/src
$ git clone https://github.com/agentzh/replace-filter-nginx-module
$ wget http://nginx.org/download/nginx-1.12.2.tar.gz
$ tar zxvf nginx-1.12.2.tar.gz
這裡採用靜態編譯的方式安裝模組,需要重新編譯 nginx
。獲取 nginx
上一次編譯引數:
$ nginx -V
nginx version: nginx/1.12.2
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-16) (GCC)
built with OpenSSL 1.0.1e-fips 11 Feb 2013
TLS SNI support enabled
configure arguments: --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-ipv6 --with-http_sub_module --with-ld-opt=-ljemalloc --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_sub_module
這裡新增 replace-filter-nginx-module
模組:
--add-module=/root/soft/src/replace-filter-nginx-module
最終編譯命令:
cd nginx-1.12.2
$ ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-ipv6 --with-http_sub_module --with-ld-opt=-ljemalloc --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --add-module=/root/soft/src/replace-filter-nginx-module
$ make
由於這裡是升級nginx,所以千萬不要make install
,不然就真的覆蓋了。 接下來手動替換二進位制檔案:
$ cp /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak
$ cp -rfp ./objs/nginx /usr/local/nginx/sbin/
測試是否可行:
$ nginx -v
nginx version: nginx/1.12.2
配置是否正常:
$ /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
配置
這裡測試的是:把介面返回的 img.test.com
換成 media.test.com
。
修改: /usr/local/nginx/conf/vhost/test.com.conf
location ~ [^/]\.php(/|$)
{
# comment try_files $uri =404; to enable pathinfo
try_files $uri =404;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
為:
location ~ [^/]\.php(/|$)
{
replace_filter 'img.test.com' 'media.test.com' g;
replace_filter_types application/json;
# comment try_files $uri =404; to enable pathinfo
try_files $uri =404;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
注意需要新增replace_filter_types
。
儲存後檢查配置是否ok:
$ /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
然後熱重啟:
# 升級完成第一次需要重啟
$ service nginx restart
# 熱重啟
$ /usr/local/nginx/sbin/nginx -s reload
