I am trying out jsonp with jQuery. I found many examples on the web and I believe my code is correct, but its still not working for me.
My web service:
using System.Web;
using System.Web.Script.Services;
using System.Web.Services;
using System.Web.Script.Serialization;..........
Firebug shows this is a success, but I am getting null from the alert. I have my webservice in iis7 locally and I am testing through my debug in my client project.
I am developing web application and in application i need to make call of jQuery using .ajax(); method with datatype is set jsonp. Now all works well with limited data but problem start to occur when data size is increasing......
EDIT: At first I thought it wasn't working cross domain at all, now I realize it only works in IE. I'm using jQuery to call a web service (ASP.NET .axmx), and trying to us jsonp so that I can call it across different sites. Right now it is working ONLY in IE, but not in Firefox, Chrome, Safari. Also, in IE, a dialog pops up warning "This page is accessing information that is not under its control..."
I´m using mvc futures 2 with WebApiEnabled for XML and JSON support. But due to cross domain issues with jQuery $.ajax I´m lookin in to JSONP. Is there a simple way to extend futures rest function for JSONP or should I do something else.
I have a simple script making a request to the server:
var DTO = { 'path': path }; var url = 'default.aspx/Get'; var test; $('#getInstance').click(function () { $.ajax({ url: url, type: 'POST', dataType: 'json', data: JSON.stringify(DTO), contentType: 'application/json; charset=utf-8', success: function (msg) { test = msg; }, error: function (jqXHR, textStatus, errorThrown) { alert(textStatus); alert(errorThrown); } }); });
This works fine as in it connects to the server and gets the data back, with one simple problem. It is treating this request as a cross domain request, therefore using jsonp. The server code is here:
[WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public static MyObject Get(string path) { MyObject foo = new MyObject(); return foo; }
Normally this would not be a problem, except that I am accessing a WebMethod, and it doesnt have the capability to return a jsonp response (meaning it has no way to attach the callback function to the response. Now, if this was a manual response, I could hack it up and attach the parameter, but I am taking advantage of the built-in serialization, so no way to mess around with the response. [URL]
Let me just stress the fact that this code works. The only problem is jQuery treating this request as cross domain. But Why? UPDATE: Well, after many more hours and more testing I have narrowed this issue down to it being a bug in jquery 1.5.1. I did some testing with older versions (all 1.4 versions) and I had no problem, the request was made using JSON, and the response was received successfully. What could be the change they made that would consider this request a CORS?
Here's briefly what I am trying to do. The File server creates a text file to indicate an end of the process. On a webpage on the Web Server, I loop every x seconds and make an ajax request to find out if the test file exists (ajax request to [URL]
I've tried the following approaches so far:
Trigger a web method from the client side that creates a HttpContext object to verify if the text file exists. But this is too strenous on the server and I started getting all kinds of exceptions in the Event Viewer.
Is there any way to get an iframe current URL after it had been changed when the user has clicked a linked inside the iframe. I am talking about cross-domain iframe. If not, is their any web browser control for ASP.net that can give me the URL of that the user is currently browsing?
I have this polling script to check if a text file is created on the server. Works great locally, but fails when the file is on a different domain. How would i rewrite this for cross domain support?
EDIT: I ended up using YQL to solve the cross domain issue and although it works, YQL is really slow that's adding quite a bit of performance overhead. Can anyone suggest a better solution for cross domain JQuery calls?
The service cannot be activated because it does not support ASP.NET compatibility. ASP.NET compatibility is enabled for this application. Turn off ASP.NET compatibility mode in the web.config or add the AspNetCompatibilityRequirements attribute to the service type with RequirementsMode setting as 'Allowed' or 'Required'.
when i try to access wcf service i get this error: the reason is HttpContext.Current is null, what should i do in this case?
Object reference not set to an instance of an object.
System.Web.Script.Serialization.JavaScriptSerializer s = new System.Web.Script.Serialization.JavaScriptSerializer(); Person p = new Person() { FirstName = "First name", LastName= "last name" }; string json = s.Serialize(p); System.Web.HttpContext.Current.Response.Write("jsoncallback" + json);} //error
How can I implement Jquery JSONP in my ASP.NET project. My application flow is described below:
1) I am opening a HTTP page, where I have got JQuery login dialog box, from which username and password is posted to my Login.aspx page, which has got one method "GetLoginDetails" which takes posted username and password and sends to a WEBSERVICE which checks the users name and password and return back with "success=true"
2) so in my response I get "success=true", I read that value from jquery and works according to responded text on my client side it display message "Logged in Successfully".
There are two web applications App1 & App2. A user would submit his information on App1 though a form. On click of a specific button/link on App1, the same data should be posted to a page on App2 and the user should also be redirected to the same page on App2.I would like some help in finding out the best way to implement this functionality.
One of the approaches that I have already tried out is by creating a temporary HTML form at runtime, setting the action attribute of the form to the App2 Page and get the form posted by using javascript submit. The data can then be fetched on App2 page by using the response.form object.This approach works well, but i was still wondering if there is any other way to implement the required functionality.
give some insights on using RESTful webservices to implement this, or else, using some HttpModule to intercept requests at App1 and modify redirect response to app2 or any other approach that you might find fit for the purpose.
I realized that IE8 does not allow links from cross domains to be displayed in IFrame. It seems like there are only two Header options that Microsoft allows to modify.
X-FRAME-OPTIONS : "DENY" (This does not display any IFrame content ) X-FRAME-OPTIONS : "SAMEORIGIN" (Displays content from the same domain)
Is there a work around to allow content from other domains to be displayed?
How can I get a user's geolocation information (City and Country - internet service provider and internet speed would also be great) based on their IP address?
I've searched and found several tools for doing this but I seem to run into problems using them with asp.net mvc. Many of them relate to using json and the "security risk" involved in cross domain ajax calls.
I have a Single Sign-on solution which is working great in our test environment. It uses Cross-Sub-Domain cookies to share the authentication ticket between 2 web applications. Sign-on is done only on one of the applications and on the second site the user is authenticated by the cookie created by the first site.The problem is that when I roll it into the production environment the single sign-on no longer works. I'm looking for any ideas on why this might be. More details below:1) Both apps are implemented using ASP.NET MVC2
I wont to restrict my web service only for few domains.
I wont to have access to web service from using ajax and my page, and I don't want that anybody can create client to my WebService and view my web service methods.
My problem is that the realm is dependent on which domain the user accessed the website on so what I did is that I set it in an global action filter like this
var module = context.HttpContext.ApplicationInstance.Modules["WSFederationAuthenticationModule"] as WSFederationAuthenticationModule; module.Realm = "http://" + siteInfo.DomainName;
My question is. When I set the realm like this, is it set per user instance or application instance.
Scenario.
User A loads the page and the realm get set to domain.a.com.
User B is already logged in on domain.b.com and presses login.
Since user A loaded the page before User B pressed login, user A will hit the STS with the wrong realm set.
What will happen here?
If this is not the way to set the realm per user instance, is there another way to do it?
I am making a asynchronous request to different server for some data using jquery. It works fine in IE, but doesn't work in FireFox and Chrome, when it reaches the code where the request to other server is made, it freezes there and a blank page is shown. If I remove that piece of code, the ajax works fine.
Also, when I place a breakpoint at document.ready, the breakpoint is hit when debugging using IE, but it's not hit when debugging using FireFox.
Following is the JQuery I am using
jQuery(document).ready(function ($) {
$('.tabs a, .tabs span').livequery('click', function () {[code]....
I have integrated Third party advertise module in my website. their domain s "http://rotator.adjuggler.com/".they read cookie from this domain and display advertise based on cookies value. now I want to set cookies on this domain from my website.though this is not possible. they have provided url to set cookies.http://rotator.adjuggler.com/servlet/cookie?action=set&name=test&value=1&maxage=2592000we can set cookies on their doemain by calling above ur.Problem:1) we can't make xmlHttp request because this is cross-doamin link.2) we can't use jquery because it uses xmlHttp as native implementation.3) i have tried to set above url in <img src="..." > and <script src="...">. both not working.but when i paste above url in address bar it works.can anybody have idea how to call above url from Code.
I'm still new to windows authentication. Basically, we have a page on http://externalsite.com that needs to be accessed only by an authenticated user originating from http://internalsite. The user on internalsite is already authenticated using windows authentication.I'm confused here. How can I validate the user and obtain their role so that i can not only validate that they are authentic, but to authorize them to use this page on externalsite.com?
I am browsing the page (http://jessie.mydomain.com/), then i click the Logout button in this page, it will be logout successful but it will not redirect to the page (http://www.mydomain.com/Default.aspx), it will show (http://jessie.mydomain.com/Default.aspx).
Here is what I want to do: I have a local site in which I want to display data from a remote site Lets say: I want to display data of http://www.abc.com/Default.aspx on my localhost
Now Default.aspx requires some post-data which it sends to itself. Thus the __viewstate and __eventvalidation are posted back to it by itself. I want to directly post the data to Default.aspx from localhost without opening Default.aspx and display the Default.aspx's response on my localhost.
The WebApp on http://www.abc.com is configured for __eventvalidation i.e. I cannot post-data to it from my localhost without getting a __viewstate from it. I also have to post the current __viewstate of http://www.abc.com/Default.aspx to itself
I have written code to access a text file in another server from my application in javascript. This code works fine in IE but fails in mozilla firefox. Below is the code i have written.
var httpRequest; httpRequest = new XMLHttpRequest(); httpRequest.open('GET', url, true); httpRequest.setRequestHeader('X-PINGOTHER','pingpong'); httpRequest.setRequestHeader('Content-Type','application/plain'); httpRequest.onreadystatechange = function() {alertContents(httpRequest); httpRequest.send(''); function alertContents(httpRequest){ if (httpRequest.readystate == 4){ if (httpRequest.status == 200) { alert(httpRequest.responseText); } } }
