Target

Want to provide the smaple RESTful server under uHTTPd on OpenWRT, I select the bash script for a demo

Reference

Bash CGI
Web CGI with Bash Script
PostMan Tester

WWW ROOT Dir on OpenWRT

/www/cgi/test.cgi

uHTTPd passes ‘GET’ paramter to bash by ‘$QUERY_STRING’
uHTTPd passes ‘POST’ conent to bash by STDIN, so bash use ‘POST_STRING=$(cat)’ to get them
