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

1. #!/bin/sh  

   ---

2. POST_STRING=$(cat)  

   ---

3. echo "Content-type: application/json" 

   ---

4. echo ""  

   ---

5. echo "$POST_STRING"  

   ---

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

Browser Client Access
