socket.io / Parameter in Verbindung

In meinem node.js /Express.js app, muss ich Parameter übergeben, mit dem sockel.io-Verbindung (habe das in einem anderen post).

Auf der client-Seite, ich habe so etwas wie :

Bearbeiten

var socket = io.connect('/image/change', {query:"name=my_img_name"});
var siofu = new SocketIOFileUpload(socket);

siofu.listenOnInput(document.getElementById("change_image_inpt"));

Auf der server-Seite :

Bearbeiten

io.of('/image/change')
  .on('connection', function (socket) {
  console.log('log input param : ' + socket.handshake.query.name);
});

Aber nichts in der Konsole.

Gibt es eine andere Möglichkeit das zu erreichen ?

Dies ist der vollständige code für den client :

$(document).ready(function() {

//icon_action_modal
$('.icon_actions').on('click', function() {
    //set icon preview
    $('#icon_action_modal_icon_preview').html('<img src="/upload/icon/' + $(this).data('icon') + '.png" />');

    //set icon to delete
    $('#icon_name').val($(this).data('icon'));

    //set Change icon socket
    var socket = io.connect('/icon_sets/change', {query:"name=my_img_name"});
    var siofu = new SocketIOFileUpload(socket);

    siofu.listenOnInput(document.getElementById("change_icon"));

    //Do something when a file is uploaded
    siofu.addEventListener("complete", function () {
        $('.overlay').hide();
    });

    //display loader window
    socket.on('displayOverlay', displayOverlay);

    //display
    socket.on('displayIconImage', function (data) {
        $('#iconset_render').append('<div class="icon"><img src="' + data.path + '" /></div>');
    });

    socket.on('setIconsetArray', function (data) {
        var iconset = ($('#iconset_array').val()) ? JSON.parse($('#iconset_array').val()) : [];

        iconset.push(data.iconName);

        $('#iconset_array').val(JSON.stringify(iconset));

        deleteIcon($('#icon_name').val());

        //close modal
        $('#icon_action_modal').modal('hide');
    });

});

$('#icon_action_modal_delete_icon').on('click', function() {
    deleteIcon($('#icon_name').val());

    //close modal
    $('#icon_action_modal').modal('hide');
});

}); //end document.ready

Und der vollständige code für die server-Seite :

io.of('/icon_sets/change')
  .on('connection', function (socket) {
    console.log('log input param : ' + socket.handshake.query.name);
    functions.socketImageTransfer(socket, 'icon', 65, 65);
});

Mit der socketImageTransfer Funktion :

module.exports.socketImageTransfer = function(socket, type, width, height, name) {

var socketioFileUploadServer    = require('socketio-file-upload');   //upload files by socket
var config                      = require(__dirname + '/config/config.json');
var easyimg                     = require('easyimage');                 //crop - resize image
var fs                          = require('fs');                        //file system access

//Make an instance of socketioFileUploadServer and listen on this socket:
var uploader = new socketioFileUploadServer();
uploader.dir = config.tmpDir;
uploader.listen(socket);

//Do something when a file is saved:
uploader.on('saved', function (event) {

    console.log('Original ' + type + ' saved');

    //resize and rename image with a unique id
    var newName;

    if (!name) {
        newName = Math.random().toString(36).substr(2, 9) + '_' + type + '.png';
    } else {
        newName = name;
    }

    var fileName = event.file.name.replace(//g, '_');

    easyimg.rescrop({src: config.tmpDir + fileName, dst: config.uploadDir + type + '/' + newName, width: width, height: height}, function (err, image) {

        if (err) return console.log(err);

        console.log(type + ' resized and cropped: ' + image.width + ' x ' + image.height);

        //image is uploaded - resized - croped, now display it
        socket.emit('display' + ucfirst(type) + 'Image', {path: '/upload/'+ type + '/' + newName});

        //remove original from file system
        fs.unlink(config.tmpDir + fileName, function () {
            if (err) throw err;
            console.log('Original ' + type + ' removed');
        });

        //additionnal action
        switch(type) {
            case 'icon':
                //send path to generate iconset_json
                socket.emit('setIconsetArray', {iconName: newName});
                break;
        }

    });

});

uploader.on('start', function (event) {
    console.log('Client start upload');
    socket.emit('displayOverlay');
});

//Error handler:
uploader.on('error', function (event) {
    console.log("Error from uploader", event);
});

};
