Iconv-lite解决gbk编码页面爬取信息时乱码问题

[Leooman]

var cheerio=require('cheerio')
var request=require('request')
var fs=require('fs')
var Iconv=require('iconv-lite')
var url=''
requestData(url,function($){
        //code
})

Buffer流处理gbk编码文件

function requestData(url,callback){
	request({
    		uri:url,
    		method:'GET',
    		encoding:'binary'
    	},function(error,response,body){
    		if(!error && response.statusCode==200){
    			body = new Buffer(body, 'binary');
		    	var result = Iconv.decode(body,'gbk');
		        var $=cheerio.load(result);
		        callback && callback($);
    		}
    	})
}
