nodejs中函数的调用实例详解

var http = require(\'http\');
http.createServer(function (request,response){
 response.writeHead(200, {\'Contet-Type\':\'text/html;charset=utf-8\'});
 
 if(request.url!==\'/favicon.ico\'){
 funl(response);
 response.end(\'\');
 } 
}).listen(8000);
console.log(\'Server running at http://127.0.0.1:8000/\');
function funl(res){
 console.log(\'fun1\');
 res.write(\'hello ,我是fun1\');
}

function fun2(res){
 console.log(\'我是,fun2\');
 res.write(\'你好我是fun2\');
}
// 想把此js声明为一个函数，加下面代码，只适用于文件中只有一个函数
module.exports = fun2;
var http = require(\'http\');
// ortherFun 就代替了fun2
var ortherFun = require(\'./../otherjs/out.js\');
http.createServer(function (request,response){
 response.writeHead(200, {\'Contet-Type\':\'text/html;charset=utf-8\'});
 
 if(request.url!==\'/favicon.ico\'){
 // funl(response);
 ortherFun(response);
 response.end(\'\');
 } 
}).listen(8000);
console.log(\'Server running at http://127.0.0.1:8000/\');
function funl(res){
 console.log(\'fun1\');
 res.write(\'hello ,我是fun1\');
}

// 支持多个函数
module.exports={
 fun2:function(res){
 console.log(\'我是fun2\');
 res.write(\'你好，我是fun2\');
 },
 fun3:function(res){
 console.log(\'我是fun3\');
 res.write(\'你好，我是fun3\');
 }
}
var http = require(\'http\');
var ortherFun = require(\'./../otherjs/out.js\');
http.createServer(function (request,response){
 response.writeHead(200, {\'Contet-Type\':\'text/html;charset=utf-8\'});
 
 if(request.url!==\'/favicon.ico\'){
 // funl(response);
 // ortherFun(response);
 ortherFun.fun2(response);
 ortherFun.fun3(response);
 response.end(\'\');
 } 
}).listen(8000);
console.log(\'Server running at http://127.0.0.1:8000/\');
function funl(res){
 console.log(\'fun1\');
 res.write(\'hello ,我是fun1\');
}

var http = require(\'http\');
var ortherFun = require(\'./../otherjs/out.js\');
http.createServer(function (request,response){
 response.writeHead(200, {\'Contet-Type\':\'text/html;charset=utf-8\'});
 
 if(request.url!==\'/favicon.ico\'){
 // funl(response);
 // ortherFun(response);
 //ortherFun.fun2(response);
 //ortherFun.fun3(response);
 
 // 用字符串调用对应的函数
 //ortherFun[\'fun2\'](response);
 //ortherFun[\'fun3\'](response);
    // 还可以写成下面这样
    funname = \'fun2\';
    ortherFun[funname](response);
 response.end(\'\');
 } 
}).listen(8000);
console.log(\'Server running at http://127.0.0.1:8000/\');
function funl(res){
 console.log(\'fun1\');
 res.write(\'hello ,我是fun1\');
}
