收集整理的這篇文章主要介紹了
nodejs-函数路由
小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.
函數(shù)------------------------------------------------------------
基本函數(shù)
function say(word) {console.log(word);
}function execute(someFunction, value) {someFunction(value);
}execute(say, "Hello");匿名函數(shù)function execute(someFunction, value) {someFunction(value);
}execute(function(word){ console.log(word) }, "Hello");路由-------------------------------------------------------------url.parse(string).query|url.parse(string).pathname || || |------ -------------------
http://localhost:8888/start?foo=bar&hello=world--- -----| || |querystring.parse(queryString)["foo"] ||querystring.parse(queryString)["hello"]router.js 文件代碼：
function route(pathname) {console.log("About to route a request for " + pathname);
}exports.route = route;server.js 文件代碼：
var http = require("http");
var url = require("url");function start(route) {function onRequest(request, response) {var pathname = url.parse(request.url).pathname;console.log("Request for " + pathname + " received.");route(pathname);response.writeHead(200, {"Content-Type": "text/plain"});response.write("Hello World");response.end();}http.createServer(onRequest).listen(8888);console.log("Server has started.");
}exports.start = start;index.js 文件代碼
var server = require("./server");
var router = require("./router");server.start(router.route);
