zhhb / basic_auth_nodejs_test.js

Created June 29, 2016 10:58 — forked from charlesdaniel/basic_auth_nodejs_test.js

Example of HTTP Basic Auth in NodeJS

	var http = require('http');

	var server = http.createServer(function(req, res) {
	// console.log(req); // debug dump the request

	// If they pass in a basic auth credential it'll be in a header called "Authorization" (note NodeJS lowercases the names of headers in its request object)

	var auth = req.headers['authorization']; // auth is in base64(username:password) so we need to decode the base64
	console.log("Authorization Header is: ", auth);

JISON sample wrapper showcasing custom error handlers (stripped JavaScript, ... where more must be done)

This code is a stripped version of actual production code hich employs this JISON clone:

(https://github.com/GerHobbelt/jison)

hence make sure to diff that one against vanilla to see differences/features.

code shows .yy.parseError, lexer.post_lex, parser.post_parser, how to get the token identifier strings from the JISON-generated parser class, etc.

Created June 8, 2016 09:58 — forked from GerHobbelt/grammar-extract.jison

snip&snap extracts from our major JISON grammar file, showcasing 'code sections' a la BISON plus a few other bits & tricks. Note the %{ ... %} sections which are JISON's 'code sections'. Also note the code following that last '%%' marker: that is another 'code section' - and the most important one.

	%options ranges
	%options backtrack_lexer

	/*
	* lexical grammar
	* ===============

	* This section defines the lexer rules for our formula parser. The rules are checked from top to bottom, so order is import
