NodeJS http响应编码

是否可以读取非 utf8 编码的网页？例如 windows-1251。我尝试使用节点图标转换结果：

var convertedBody = new Iconv('windows-1251','utf-8').convert(responseBody));

但我得到异常：

Error: EILSEQ, Illegal character sequence.
    at IncomingMessage.<anonymous> (/root/nodejstest/test2.js:22:19)
    at IncomingMessage.emit (events.js:59:20)
    at HTTPParser.onMessageComplete (http.js:111:23)
    at Socket.ondata (http.js:1183:22)
    at Socket._onReadable (net.js:654:27)
    at IOWatcher.onReadable [as callback] (net.js:156:10)

谢谢！

Is in possible to read web page in non utf8 encoding? For example windows-1251.
I tried to convert result using node-iconv:

var convertedBody = new Iconv('windows-1251','utf-8').convert(responseBody));

But I get exception:

Error: EILSEQ, Illegal character sequence.
    at IncomingMessage.<anonymous> (/root/nodejstest/test2.js:22:19)
    at IncomingMessage.emit (events.js:59:20)
    at HTTPParser.onMessageComplete (http.js:111:23)
    at Socket.ondata (http.js:1183:22)
    at Socket._onReadable (net.js:654:27)
    at IOWatcher.onReadable [as callback] (net.js:156:10)

Thanks!

这是您问题的有效解决方案。您必须首先使用 Buffer 并将字符串转换为二进制。

request({ 
uri: website_url,
method: 'GET',
encoding: 'binary'
}, function (error, response, body) {
    body = new Buffer(body, 'binary');
    conv = new iconv.Iconv('windows-1251', 'utf8');
    body = conv.convert(body).toString();
     }
});

Here is working solution to your problem. You have to use Buffer and convert your string to binary first.

request({ 
uri: website_url,
method: 'GET',
encoding: 'binary'
}, function (error, response, body) {
    body = new Buffer(body, 'binary');
    conv = new iconv.Iconv('windows-1251', 'utf8');
    body = conv.convert(body).toString();
     }
});

查看 iconv-lite 库。
使用它你的代码可能如下所示：

var iconv = require('iconv-lite');
request(
    { 
        uri: website_url,
        method: 'GET',
        encoding: 'binary'
    },
    function(err, resp, body){
        body = iconv.decode(body, 'win1251');
    }
);

Take a look at the iconv-lite library.
Using it your code may look like this:

var iconv = require('iconv-lite');
request(
    { 
        uri: website_url,
        method: 'GET',
        encoding: 'binary'
    },
    function(err, resp, body){
        body = iconv.decode(body, 'win1251');
    }
);

Iconv 没有 windows-1251。

您可以从 bnoordhuis/node-iconv 验证编码列表。

顺便说一句，来自维基百科：

Windows-1251 和 KOI8-R（或其乌克兰变体 KOI8-U）比 ISO 8859-5 更常用。

const request = require('request');
const iconv = require('iconv-lite');

request({
    url: 'http://meta.ua',
    encoding: 'binary',
}, (err,res,body) => {
    if (err) throw err;

    var decoded = iconv.decode(res.body, 'win1251');

    console.log(decoded);
});

const request = require('request');
const iconv = require('iconv-lite');

request({
    url: 'http://meta.ua',
    encoding: 'binary',
}, (err,res,body) => {
    if (err) throw err;

    var decoded = iconv.decode(res.body, 'win1251');

    console.log(decoded);
});
