nginx 日志json化和静态文件不打印日志

1.定义日志为json格式，参数可以通过 $arg_参数名获取

log_format  tongji  '{"createTime":"$time_iso8601",'   

'"source":"$server_addr",'             

'"client":"$remote_addr",'             

'"size":$body_bytes_sent,'             

'"responsetime":"$request_time",'      

'"upstreamtime":"$upstream_response_time",'                  

'"upstreamaddr":"$upstream_addr",'     

'"request_method": "$request_method",'

'"domain":"$host",'                    

'"url":"$uri",'  

'"args":"$args",'

'"id":"$arg_id",'

'"type":"$arg_type",'                  

'"http_user_agent": "$http_user_agent",'                     

'"status":$status,'                    

'"x_forwarded_for":"$http_x_forwarded_for"}’;

2.设置图片不打印日志

注意：因为每个请求会默认访问一个ico文件，导致每个请求都是多个，所以做好设置一下

server {                                                                                                                                                               

    listen       80;                                                                                                                                                   

    server_name  tongji.haoyunbang.cn;                                                                                                                                 

    access_log  logs/tongji.haoyunbang.access.log  tongji;                                                                                                             

    location / {                                                                                                                                                       

        content_by_lua '                                                                                                                                               

                ngx.header.content_type = "text/plain";                                                                                                                

                ngx.say("1");                                                                                                                                          

        ';                                                                                                                                                             

    }                                                                                                                                                                  

    location ~ .*\.(js|css|ico|gif|jpg|jpeg|png|bmp|swf)$ {                                                                                                                   

                                                                                                                                                                       

        expires 7d;                                                                                                                                                    

        access_log off;       

        proxy_pass   http://wwwserv;  #如果图片和网站放在一起，必须加这个转向                                                                                                                                         

    }
