抓取這個(gè)網(wǎng)頁(yè)http://www.runoob.com/nodejs/...出現(xiàn)亂碼，網(wǎng)頁(yè)編碼為utf-8，用過(guò)iconv-lite還是不行，這是為什么？var http=require("http");var go=require("iconv-lite") http.get("http://www.runoob.com/nodejs/nodejs-tutorial.html",function(res){    var html="";     res.on("data",function(data){       /* html +=go.decode(data,"gb2312");*/         html+=data;     })     res.on("end",function(){        console.log(html);     }).on("error",function(){        console.log("獲取失敗")     }) })
