    Enabling Authentication

    Hello,

    I have a working lightstreamer integration based on a node js / javascript client implementation.

    I have the following adapter.xml:

    <adapter_class>com.lightstreamer.adapters.remote.m etadata.RobustNetworkedMetadataProvider</adapter_class>
    <classloader>log-enabled</classloader>
    <param name="request_reply_port">6662</param>
    <param name="timeout">36000000</param>
    </metadata_provider>
    <data_provider>
    <adapter_class>com.lightstreamer.adapters.remote.d ata.RobustNetworkedDataProvider</adapter_class>
    <classloader>log-enabled</classloader>
    <param name="request_reply_port">6663</param>
    <param name="notify_port">6664</param>
    </data_provider>


    I also have a notifyUser listener:

    metadataProvider.on('notifyUser', function(request, response){

    console.log("notifyUser...");
    console.log(request);
    console.log(request['userName']);
    console.log(request['userPassword']);
    response.success();

    });

    This prints the following:

    notifyUser...
    { id: '10000014588ddcd8a',
    verb: 'notifyUser',
    userName: null,
    userPassword: null,
    headers:
    { 'content-type': 'application/x-www-form-urlencoded; charset=UTF-8',
    'cache-control': 'no-cache',
    connection: 'keep-alive',
    host: 'localhost',
    'accept-language': 'en-US,en;q=0.5',
    accept: 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
    'content-length': '147',
    origin: 'https://localhost:4433',
    'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:28.0) Gecko/20100101 Firefox/28.0',
    'accept-encoding': 'gzip, deflate',
    referer: 'https://localhost:4433/view1',
    pragma: 'no-cache',
    REQUEST_ID: '294' } }
    null
    null

    ... and then crashes the server.

    1) the userName and userPassword fields are null - where exactly do these need to be passed so that they are available here to carry out the authentication?

    2) Why does the server then crash?

    3) I have had a long look and play around with the code. I can't seem to find the correct documentation on the arguments that will be passed to :

    metadataProvider.on('notifyUser',........

    Thanks in advance.

    Hi,

    1) it depends on the client library in use. As an example, if you're using the JavaScript client library you would do



    see http://www.lightstreamer.com/distros...onDetails.html

    2) which server crashes? Lightstreamer or node.js? Do you get any error?

    3) you can find it here: http://www.lightstreamer.com/distros...dcca465d0.html
