Background: Sometimes the program even if the parameter is less or not submitted to the next link in the URL after the problem, how to check it, the best way is to add the post parameters on the Nginx, to locate the problem can be a UiR code to troubleshoot problems.

Og_format access ' $remote _addr-$remote _user [$time _local] "$request" $status $body _bytes_sent $request _body "$http _ Referer "" $http _user_agent "$http _x_forwarded_for ';

Access_log Logs/test.access.log access;

Note the placement in http: nginx: [Warn] the "log_format" directive May is used only on "HTTP" level in/usr/local/nginx/conf/vhost/xxx. conf:59

Nginx.conf

HTTP definition: Wwwlog

Log_format wwwlog ' $remote _addr-$remote _user [$time _local] "$request" '

' $status $body _bytes_sent ' $http _referer '

' "$http _user_agent" $http _x_forwarded_for "$request _time";

Add Wwwlog to the include each domain name:

Access_log/data/logs/access_mytv.log Wwwlog;

So after the same access, write this:

Nginx.conflog_format access ' $remote _addr-$remote _user [$time _local] "$request" $status $body _bytes_sent $request _ Body "$http _referer" "$http _user_agent" $http _x_forwarded_for '; included Justwinit.conf:access_log  /data/logs/access _mytv.log Access

The logs are as follows:

As shown in the previous file, you only need to use $request_body to post data, and in the existing server segment add the following settings:

Log_format access ' $remote _addr-$remote _user [$time _local] "$request" $status $body _bytes_sent $request _body "$http _ Referer "" $http _user_agent "$http _x_forwarded_for ';
