使用iconv 从gb2312转utf-8经常出错? 400 报错

/** * 采集39问答网 */

var n = require('needle') var $ = require('jquery') var iconv = require('iconv').Iconv; n.get('http://ask.39.net/browse/313-2-1.html',{encoding:'gb2312'},function(error,response,body){ //console.log(response.statusCode) var buf = new Buffer(body,'binary'); var content = new iconv('gb2312','UTF8').convert(buf).toString() //采集到的链接 var $(content).find('.bt').each(function(index,value){ href[$(value).attr('href')] = $(value).attr('href') }) console.log(href) })

经常出现下面的错误

D:\node.js\node_modules\iconv\lib\iconv.js:85
          throw errnoException('EILSEQ', 'Illegal character sequence.');
                ^

不知道有没有其他的方式进行编码转换
