NodeJS: 处理request网页乱码问题

对于gb2312编码的网页，直接用request去获取会得到乱码的结果，解决方法很简单：

1. npm install iconv-lite

2. var iconv = require('iconv-lite');

3.

request.get({
    url : url ,
    encoding : null //让body 直接是buffer
}, response);

4.

var response = function (err, response, body) {
    //返回的body 直接就是buffer 了...
    var buf =  iconv.decode(body, 'gb2312');
    ...
    ...
}

done.
