app.js代码：
// 内置http模块，提供了http服务器和客户端功能 var http=require("http"); // 内置文件处理模块 var fs=require('fs'); // 创建一个将流数据写入文件的WriteStream对象 var outstream=fs.createWriteStream('./retval.html'); // 请求参数JSON var options={ hostname:'www.cnblogs.com',// 这里别加http://，否则会出现ENOTFOUND错误 port:80, path:'/xiandedanteng',// 子路径 method:'GET', }; // 请求并获得数据 var req=http.request(options,function(resp){ console.log('状态码resp.statusCode='+resp.statusCode); console.log('响应头resp.headers='+JSON.stringify(resp.headers)); resp.setEncoding('utf8'); resp.on('data',function(chunk){ console.log('响应内容:'+chunk); outstream.write(chunk,'utf8'); console.log('文件写入完毕。'); }); }); // 超时处理 req.setTimeout(5000,function(){ req.abort(); }); // 出错处理 req.on('error',function(err){ if(err.code=="ECONNRESET"){ console.log('socket端口连接超时。'); }else{ console.log('请求发生错误，err.code:'+err.code); } }); // 请求结束 req.end();
获得的数据文件如下：
