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
