1、案例一
var fs = require("fs");
console.log("starting");
//读取文件中的内容
var content
=fs.readFileSync("./Node.js.txt");
console.log("content"+content);
//监听文件中的内容是否有变化,如果改变
,显示出新的内容
fs.watchFile("./config.json",function(current,previous){
console.log("config changed");
content=
JSON.parse(fs.readFileSync("./config.json"));
console.log(content);
});
2、案例二】
//监听网页的地址
var fs = require("fs");
var config
=JSON.parse(fs.readFileSync("config.json"));
var host =
config.host;
var port = config.port;
var express =
require("express");
var app = express();
app.get("/"
,function(request,response){
response.send("hello");
});
app.get("/:id"
,function(request,response){
response.send("hello"+request.params.id);
});
app.listen(port,host);
