+Lighttpd: CGI with Python
+------------------------------
+
+* Enable CGI in lighttpd:
+
+ * Create: /etc/lighttpd/conf-available/95-testing-cgi.conf
+
+ #-- Alias.
+ alias.url += ( "/testing" => "/home/user/path/to/testcgi/dir" )
+
+ #-- Server.
+ $HTTP["url"] =~ "^/testing" {
+ cgi.assign = ("" => "")
+ }
+
+ * Enable the configuration.
+
+ ln -s /etc/lighttpd/conf-available/95-testing-cgi.conf /etc/lighttpd/conf-enabled/95-testing-cgi.conf
+
+ * Restart lighttpd:
+
+ systemctl restart lighttpd.service
+
+
+* Simple python http cgi server:
+
+ tree
+ +-- cgi-bin
+ | +-- retrieval.py
+ +-- forms.html
+
+ chmod +x cgi-bin/retrieval.py
+ python -m CGIHTTPServer 8088
+ http://localhost:8000/forms.html
+
+
+* Simple python https cgi server:
+
+ tree
+ +-- retrieval.py
+ +-- forms.html
+
+ * Generate the https certificate:
+ openssl req -x509 -newkey rsa:4096 -keyout servercgi.pem -out servercgi.pem -days 3650 -nodes
+
+ * servercgi.py:
+ #!/usr/bin/env python3
+ import cgitb, getpass, http.server, os, ssl, sys
+
+ PUERTO = 9099
+
+ def Main():
+ nombre = getpass.getuser()
+ if (nombre != 'myusername'):
+ print('ERROR: use only with the user myusername.')
+ return
+
+ os.environ['PYTHONDONTWRITEBYTECODE'] = 'TRUE'
+ os.chdir('/path/to/tree')
+ cgitb.enable()
+ server = http.server.HTTPServer
+ handler = http.server.CGIHTTPRequestHandler
+ srvaddr = ('', PUERTO)
+ handler.cgi_directories = ['/']
+ srvobj = server(srvaddr, handler)
+ srvobj.socket = ssl.wrap_socket(srvobj.socket, certfile='servercgi.pem', server_side=True)
+ handler.have_fork=False
+ print('Page: https://127.0.0.1:' + str(PUERTO) + '/retrieval.py')
+ srvobj.serve_forever()
+ return
+
+ Main()
+
+ * Start the server with ./servercgi.py
+
+ * Testing script: /path/to/tree/retrieval.py
+
+ #! /usr/bin/env python3
+ import cgi, cgitb
+
+ cgitb.enable(format='html')
+ #cgitb.enable(format='text')
+
+ def ShowHtml():
+ print('Content-Type: text/html; charset=UTF-8')
