请求body添加：

 在nginx配置文件log_format添加request_body:"$request_body" 

响应body添加：

需要借助lua模块

1.下载安装LuaJIT

cd /usr/local/src
wget http://luajit.org/download/LuaJIT-2.0.5.tar.gz
tar -xzvf LuaJIT-2.0.5.tar.gz
cd LuaJIT-2.0.5
make
make install

出现如下内容，表示安装成功
==== Successfully installed LuaJIT 2.0.2 to /usr/local ====

2.下载nginx lua模块

cd /usr/local/src
wget https://github.com/chaoslawful/lua-nginx-module/archive/v0.10.15.tar.gz
tar -xzvf v0.10.15.tar.gz

3.nginx添加lua模块

• a.查看原来的编译参数

[root@iZwz9b8dyz1jpybdicn3lcZ nginx]# ./sbin/nginx -V
nginx version: nginx/1.15.8
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-23) (GCC) 
built with OpenSSL 1.0.1e-fips 11 Feb 2013
TLS SNI support enabled
configure arguments: --user=www --group=www --prefix=/www/wdlinux/nginx-1.15.8 --with-http_stub_status_module --with-ipv6 --with-http_gzip_static_module --with-http_realip_module --with-http_ssl_module

• b.从新编译，添加模块

cd /usr/local/src/nginx
./configure --user=www --group=www --prefix=/www/wdlinux/nginx-1.15.8 \
--with-http_stub_status_module --with-ipv6 --with-http_gzip_static_module \
--with-http_realip_module --with-http_ssl_module --add-module=/usr/local/src/lua-nginx-module-0.10.15
make

• c.make编译完后不要执行make install 在objs下面有一个nginx执行文件

• d.备份原来nginx可执行文件

mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.old

• e.吧新的nginx文件copy到原来nginx运行sbin目录下

cp objs/nginx /usr/local/nginx/sbin/nginx

• f.测试查看编译参数

 /usr/local/nginx/sbin/nginx -t 

• g.执行make upgrade替换老的nginx进程

make  upgrade

• h.再次执行nginx -V将会显示新的nginx的版本及编译的参数

4.测试lua是否安装成功

• vi nginx.conf在server 中添加一个localtion

location /hello {
   default_type 'text/plain';
   content_by_lua 'ngx.say("hello, lua")';
  }

• 重启nginx

/usr/local/nginx/sbin/nginx -s reload

访问url会返回hello, lua则表示成功

5.修改nginx.conf文件增加返回响应body

• a.修改log_format添加resp_body

log_format  api  '$remote_addr - requesttime:"$request_time"  $remote_user [$time_local] "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for"  "user_token": "$http_authorization"'
                  'request_body:"$request_body"  resp_body:"$resp_body" ' ;

• b.server添加响应内容，然后重启nginx

server {
  access_log /var/log/nginx/access.log api;
  #记录nginx请求返回值
  lua_need_request_body on;
  set $resp_body "";
  body_filter_by_lua '
   local resp_body = string.sub(ngx.arg[1], 1, 1000)
   ngx.ctx.buffered = (ngx.ctx.buffered or "") .. resp_body
   if ngx.arg[2] then
    ngx.var.resp_body = ngx.ctx.buffered
   end
  ';
  location / {
   proxy_pass http://127.0.0.1:5000;
   }
 }

日志响应内容如下

使用python解码对应的req body或者resp body
