使用ISO-8859-1编码发送请求

Question

I have a little problem, the data I want to request from our SVN server (VisualSVN) are encoded as ISO-8859-1, when I try to request them with node.js https module it doesn't encode ä, ö, ü, etc. correctly.

My question is, how can I tell node to request the data as ISO-8859-1?

PS: I would like to stick with the buildin components, if this isn't possible, I am open for ideas :)

This the code I use to get files

exports.getSvnFile = function (path, auth, callback) {
    var options = {
        host: app.getSetting('svnserver'),
        method: 'GET',
        path: '/svn/' + encodeURIComponent(path).replace(/%2F/g, '/'),
        auth: tools.readFromSession(auth, 'username') + ':' + tools.readFromSession(auth, 'password'),
        headers: {
            'Accept-Charset': 'iso-8859-1'
        }
    }
    try {
        https.request(options, function (res) {
            var result = []
            try {
                console.log('STATUS: ' + res.statusCode)
                console.log('CONTENT-TYPE: ' + res.headers['content-type'])
                var data = ''
                res.on('data', function (chunk) {
                    data += chunk
                })
                res.on('end', function () {
                    callback(data, res.headers['content-type'])
                })
                res.on('error', function (err) {
                    console.error(err)
                })
            } catch (ex) {
                console.error(ex)
            }
        }).end()
    } catch (ex) {
        console.error(ex)
        callback([])
    }
}

The data I get out there are already broken, when the res.end part gets called. I thought maybe the Accept-Charset header might help but apparently it didn't.

I might have the solution, for me at least it worked :)

Here is the code from above adjusted:

exports.getSvnFile = function (path, auth, callback) {
    var options = {
        host: app.getSetting('svnserver'),
        method: 'GET',
        path: '/svn/' + encodeURIComponent(path).replace(/%2F/g, '/'),
        auth: tools.readFromSession(auth, 'username') + ':' + tools.readFromSession(auth, 'password')
    }
    try {
        https.request(options, function (res) {
            var result = []
            res.setEncoding('binary')
            try {
                console.log('STATUS: ' + res.statusCode)
                console.log('CONTENT-TYPE: ' + res.headers['content-type'])
                var data = ''
                res.on('data', function (chunk) {
                    data += chunk
                })
                res.on('end', function () {
                    callback(data, res.headers['content-type'])
                })
                res.on('error', function (err) {
                    console.error(err)
                })
            } catch (ex) {
                console.error(ex)
            }
        }).end()
    } catch (ex) {
        console.error(ex)
        callback([])
    }
}

It is nearly identical except of one thing, the encoding is set to binary then it worked perfectly :)
