Windows Phone 7 Application + WCF + SSL + Username Authentication

- by s7orm

Hello, I have developed a test service with WCF, which I try to consume from a Windows Phone 7 Application, however when calling a method from the service I get a weird exception: There was no endpoint listening at https://server/Service.svc that could accept the message. This is often caused by an incorrect address or SOAP action. The WCF service uses a custom binding with UserNameOverTransport authentication and SSL. For the authorization I am using an implementation of the UserNamePasswordValidator. If I try to consume the service from a console or silverlight application (cross domain policy is enabled) - it works fine (authorization as well). And the most weird thing is that the ServiceReferences.ClientConfig file generated for the WP7 App is exactly the same as the config file generated for the silverlight application. I have no idea what is wrong with my service...

Cannot connect to MySQL 4.1+ using old authentication

- by B T

I'm trying to connect to a mySQL database at http://bluesql.net, but when I try to connect, it gives this error: Connect Error (2000) mysqlnd cannot connect to MySQL 4.1+ using old authentication I've looked into this, and it has to do with some old password scheme used before MySQL 4.1. Newer versions have the option to use old passwords, which I've read may cause this problem. I'm running php 5.3, and connecting with mySQLi (new mysqli(...)). I'm hoping I can do something in the code to connect to the DB at bluesql.net - clearly I don't control how their database is set up. Downgrading php versions isn't an option. Anyone have any ideas?

How do I stack Plack authentication handlers?

- by Schwern

I would like to have my Plack app try several different means of authorizing the user. Specifically, check if the user is already authorized via a session cookie, then check for Digest authentication and then fall back to Basic. I figured I could just enable a bunch of Auth handlers in the order I wanted them to be checked (Session, Digest, Basic). Unfortunately, the way that Plack::Middleware::Auth::Digest and Plack::Middleware::Auth::Basic are written they both return 401 if digest or basic auth doesn't exist, respectively. How is this normally dealt with in Plack?

Web Application - Authentication / Login Framework

- by user456563

This is a very simple, probably a most asked question and frequently developed as part of any web application. Say I'm planning to build a web application and some of the functional requirements include (apart from the usual hard hitting security reqs), - Need to have users sign up for a new account profile - Authenticate user using the native app authentication / Facebook or Google or Yahoo or OpenId login - Allow lost password retrieval - Session handling needs Is there an out of the box frameworks (Drupal, Liferay??) that I can use to wrap my application which can be a bunch of JSP's or HTML's with JS? I know I'm asking a very simple and maybe a naive question. But this is a topic every web developer guru will go thru. Any help, advise and pointers much appreciated.

Established javascript solution for secure registration & authentication without SSL

- by Tomas

Is there any solution for secure user registration and authentication without SSL? With "secure" I mean safe from passive eavesdropping, not from man-in-the-middle (I'm aware that only SSL with signed certificate will reach this degree of security). The registration (password setup, i.e. exchanging of pre-shared keys) must be also secured without SSL (this will be the hardest part I guess). I prefer established and well tested solution. If possible, I don't want to reinvent the wheel and make up my own cryptographic protocols. Thanks in advance.

User forms authentication in JSF

- by Proton

I'm a novice at JSF and I got a couple of questions concerning organizing user authentication there. 1) How can i redirect the registered user to a welcome page (for example welcome.xhtml)? I heard about using Filter or navigation-rule tag, but i didn't found a full-blown tutorial of how it works. 2) How can i tell the server that unauthorized users can access not only the login page but also the registration page? Is there an analog for ASP.NET web.config tag or something like this?

Best Solution For Authentication in Ruby on Rails

- by Dan Wolchonok

I'm looking for a pre-built solution I can use in my RoR application. I'm ideally looking for something similar to the ASP.NET Forms authentication that provides email validation, sign-up controls, and allows users to reset their passwords. Oh yeah, and easily allows me to pull the user that is currently logged into the application. I've started to look into the already written pieces, but I've found it to be really confusing. I've looked at LoginGenerator, RestfulAuthentication, SaltedLoginGenerator, but there doesn't seem to be one place that has great tutorials or provide a comparison of them. If there's a site I just haven't discovered yet, or if there is a de-facto standard that most people use, I'd appreciate the helping hand.

download authentication?

- by Sahat

Hi I am sorry if this question has been asked before but I am looking for some sort of download authentication. In other words if I am going to give the user a link to a file, I want to make sure only that person will get it, and get it only once! Is there a simple solution without setting up the whole database. Even better if it's possible to have an ecrypted web link that will let you download a file from my FTP server just once, after that the link becomes invalid. Thanks.

How can I use JSONP to download client-side javascript objects?

- by Alex Mcp

I'm trying to get client-side javascript objects saved as a file locally. I'm not sure if this is possible. The basic architecture is this: Ping an external API to get back a JSON object Work client-side with that object, and eventually have a "download me" link This link sends the data to my server, which processes it and sends it back with a mime type application/json, which (should) prompt the user to download the file locally. Right now here are my pieces: Server Side Code <?php $data = array('zero', 'one', 'two', 'testing the encoding'); $json = json_encode($data); //$json = json_encode($_GET['']); //eventually I'll encode their data, but I'm testing header("Content-type: application/json"); header('Content-Disposition: attachment; filename="backup.json"'); echo $_GET['callback'] . ' (' . $json . ');'; ?> Relevant Client Side Code $("#download").click(function(){ var json = JSON.stringify(collection); //serializes their object $.ajax({ type: "GET", url: "http://www.myURL.com/api.php?callback=?", //this is the above script dataType: "jsonp", contentType: 'jsonp', data: json, success: function(data){ console.log( "Data Received: " + data[3] ); } }); return false; }); Right now when I visit the api.php site with Firefox, it prompts a download of download.json and that results in this text file, as expected: (["zero","one","two","testing the encoding"]); And when I click #download to run the AJAX call, it logs in Firebug Data Received: testing the encoding which is almost what I'd expect. I'm receiving the JSON string and serializing it, which is great. I'm missing two things: The Actual Questions What do I need to do to get the same prompt-to-download behavior that I get when I visit the page in a browser (much simpler) How do I access, server-side, the json object being sent to the server to serialize it? I don't know what index it is in the GET array (silly, I know, but I've tried almost everything)

Drupal JSON POST from PhoneGap

- by abritez

I am trying to send a POST request to Drupal's Services module & JSON_Server module, however I am getting { "#error": true, "#data": "Invalid method " } Since PhoneGap runs html files from locally on the phone, should i need to worry about JSONP. The issue I have with that is that I must POST data, and JSONP only allows for GET. Any ideas would be helpful. Thanks! //SEND REQUEST AND CALLBACK FUNCTION var req; DrupalService.prototype.request = function(dataObject, callback){ req = false; var url = DRUPAL_JSON_URL; var params = "data="+dataObject; try { req = new XMLHttpRequest(); } catch(e) { req = false; } if(req) { req.onreadystatechange = function() {//Call a function when the state changes. if(req.readyState == 4 && req.status == 200) { console.log(" "+req.responseText); } } req.open("POST", url, false); req.send(params); } }

Android compatibility with Restlet/JSON/Jackson

- by Cookie

Hi there, I'm currently working on a webservice-client for Android. I'm using a Java client library which provides an abstraction for interaction with the service. The client library works on normal machines. However, when I use the classes in my Android project, some calls don't return a result on Android, the background-service stops working at the first of those commands. Wireshark shows a tcp exchange, the server gets the requests. There is no exceptions or anything. Something in the serialization/deserialization semms not to work. I'm using the newest version of Jackson libraries (1.5.3) and the restlet jar in the android edition. Is there any known problems with Jackson and Android? Which code and libraries are compatible with Android? Thanks in advance.

JSON / JSONP in JQuery

- by dotnetgeek

Hello. I am trying to figure out why my $.getJSON method does not seem to be working but the $.ajax works just fine. First, here is my getJSON call: $.getJSON("http://localhost:1505/getServiceImageList?callback=loadImagesInSelect", loadImagesInSelect); You can see I have tried added the callback parameter directly to the query string (also tried it not on string) and I added a reference to the callback method defined in my js file. Here is the $.ajax call which works just fine: function getImages() { $.ajax({ type: "GET", url: $('#txt_registry_url').val(), dataType: "jsonp", success:loadImagesInSelect , error:function (xhr, ajaxOptions, thrownError) { alert(xhr.status); alert(thrownError); } }); } In this example the url pulled from the text box is the same as in the straight call to getJSON. When the method call completes, the successMethod is called and everything processes just fine. While I am cool with using the later of the two methods, the docs make it seem that the getJSON is the preferred shorthand way of doing things. Can anyone please explain what I am missing on the shorthand method to make it all work? Thanks in advance.

adding to json property that may or may not exist yet

- by mmcgrail

let say i want to do this var dasboard = {}; $('.check').click(function(){ $(this).toggleClass("active").siblings().slideToggle('slow', function() { dashboard['pages']['pagename'][$(this).closest('li').attr("id")]['show'] = $(this).is(":hidden") ? 'collapsed' : 'expanded'; }); } i get an error saying 'dashboard.pages is undefined' is there away to dynamically add 'pages' and the children that follow without having to do the work of checking to see if it is defined first then if its not doing dashboard['pages'] = {}; because sometimes they may already exist and I don't want to have to inspect the tree first i just want to build the branches as needed

Null date reference when passing json to MVC Controller

I am building an event system that posts data to a google calendar. I am using jquery 1.4.2, fullcalendar 1.4.5, and asp.net MVC 2. I am using a jquery ui modal dialog for the entry system.

jQuery JSON encode set of input values

- by gurun8

I need tp serialize a group of input elements but I can't for the life of me figure out this simple task. I can successfully iterate through the targeted inputs using: $("#tr_Features :input").each(function() { ... } Here's my code, that doesn't work: var features = new Array(); $("#tr_Features :input").each(function() { features += {$(this).attr("name"): $(this).val()}; } Serializing the entire form won't give me what I need. The form has much more than this subset of inputs. This seems like it should be a pretty straightforward task but apparently programming late into a Friday afternoon isn't a good thing. If it's helpful, here's the form inputs I'm targeting: <table cellspacing="0" border="0" id="TblGrid_list" class="EditTable" cellpading="0"> <tbody><tr id="tr_Features" class="FormData" rowpos="1"> <td class="CaptionTD ui-widget-content">Cable Family</td> <td id="td_Features" class="DataTD ui-widget-content" style="white-space: pre;"> <input type="text" value="" id="feature_id:8" name="feature_id:8"></td> </tr> <tr id="tr_Features" class="FormData" rowpos="1"> <td class="CaptionTD ui-widget-content">Material</td> <td id="td_Features" class="DataTD ui-widget-content" style="white-space: pre;"> <input type="text" value="" id="feature_id:9" name="feature_id:9"></td> </tr> <tr id="tr_Features" class="FormData" rowpos="1"> <td class="CaptionTD ui-widget-content">Thread Size</td> <td id="td_Features" class="DataTD ui-widget-content" style="white-space: pre;"> <input type="text" value="" id="feature_id:10" name="feature_id:10"></td> </tr> <tr id="tr_Features" class="FormData" rowpos="1"> <td class="CaptionTD ui-widget-content">Attachment Style</td> <td id="td_Features" class="DataTD ui-widget-content" style="white-space: pre;"> <input type="text" value="" id="feature_id:11" name="feature_id:11"></td> </tr> <tr id="tr_Features" class="FormData" rowpos="1"> <td class="CaptionTD ui-widget-content">Feature</td> <td id="td_Features" class="DataTD ui-widget-content" style="white-space: pre;"> <input type="text" value="" id="feature_id:12" name="feature_id:12"></td> </tr> <tr id="tr_Features" class="FormData" rowpos="1"> <td class="CaptionTD ui-widget-content">Comments</td> <td id="td_Features" class="DataTD ui-widget-content" style="white-space: pre;"> <input type="text" value="" id="feature_id:13" name="feature_id:13"></td> </tr> </tbody></table>

I would copy and past it here, but that isn't working. What am I doing wrong?
