I'm trying to hide the data from begin watched in the url, For example here is my route :
routes.MapRoute(
"Viewer",
"viewer/{id}",
new { controller = "Viewer", action = "Index" }
);
and here is the controller method:
public ActionResult Index(int id)
{}
as you see when i call the method it's gonna route and show the url like this :
www.domain.com/viewer/1234
I want to remove the Id from begin watched and i want keep the method running as expected like this
www.domain.com/viewer
So how i can do that ?
As you, Since you want to pass data with GET request, you have to send id or everything else that you can search and find that data. I suggest you hash URL. To hashing URL:
url hash

I have a asp.net mvc form and i want to submit it to same page via get method, it's used for search purpose.
The url is mapped with route key value id.
#using (#Html.BeginForm("Contact", "Home",FormMethod.Get))
{
#Html.TextBox("id", null,
new
{
type = "time"
}
);
<input type="submit" />
}
When the form is generated the action attribute is containing the key value like /Home/Contact/myname.
Here myname is value of id present in url.
When form is submitted value key value for id is getting appended to URL like
http://localhost:57247/Home/Contact/myname?id=11%3A11
The action method is reading myname value instead of 11%3A11.
Action Method:
public ActionResult Contact(string id)
{
ViewBag.Message = id;
return View();
}
It's working fine with post method.
How to fix this?
replace #Html.BeginForm("Contact", "Home",FormMethod.Get)
with #Html.BeginForm()
By default forms are sent to same url they are rendered on and default method is get.
#Html.BeginForm() by default produces a METHOD="POST"
As for your parameter you might want to name it differently.
Default Mvc route is configured like this
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
Depending on mvc version it can be in global.asax or App_Start\routeconfig.cs
So your "MyName" in url perfectly matches default id parameter and it has higher priority than query string parameters.
If you name your parameter differently (not id).
Change it to "q" for example in action and in view.
Your URLs will change to /Home/Contact?q=myname and everything should start working as expected.
Now you say that you want a solution with url mapping.
So you have to figure out for yourself what url scheme you want.
If you have a form and want it to post to /home/contact/myname?id=notyourname, than you have a conflict which to solve you will have to somehow change binding priorities in mvc.
Now you can inspect querystring on your own in your action and figure out new id passed without binding. After that you can return RedirectToAction("Contact", new{id = figuredId}) and the url in browser will be what you want it to be.
You can change the query parameter name and have your action recieve 2 parameters
public ActionResult Contact(string id, string q){
if (!string.IsNullOrWhitespace(q)){
return RedirectToAction("Contact",new{id=q});
}
}
To send request to /Home/Contact you should use #Html.BeginForm("Contact","Home",new{id=null}, FormMethod.Get)
I am beginner for .net MVC. I guess my problem is related to route setting.
What I want to do is :I get data from database, in controller transfer data to json format and pass to view, use javascript decode json data and show on the html.
When I write methods under TechnologyController, type localhost:portnumber/Technology/Index, no decoded json data in html format, but if I type localhost:portnumber/Technology/GetJson
It show me a page with pure json data (which means if I call GetJson() method separately, it works)
I write the same code in HomeController, it runs correct, all the route setting is default:
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
//This is my controller
public class TechnologyController : Controller
{
public ActionResult Index()
{
return View();
}
public JsonResult GetJson()
{
Technology myTech = new Technology(); //get data from database (Tested correct)
return Json(myTech.select(), JsonRequestBehavior.AllowGet);
}
}
//This is Javascript:
<script type="text/javascript">
$(document).ready(function() {
$.getJSON("Technology/GetJson/", null, function(data) {
sss.innerHTML+=data["title"];// this part is correct (I already tested,please ignore), the purpose is to parse json data to html.
.......
}
)};
)};
I understand if I call "localhost:portnumber/Technology/Index", it only execute index method, that is why GetJson method is not called, but what url should I call in order to call index() as well as GetJson.
something like:
$.getJSON("#Url.Action("GetJson","Technology"), null, function(data) {
edit 2-
Without Razor it would look like this:
$.getJSON("<%= Url.Action("GetJson","Technology") %>, null, function(data) {
Edit-
Wait you want to call Index AND GetJson? That should already be happening, just load the /index page which calls index controller action, then in the rendered script from there your invoking the GJson action. Why would you think you need to call Index again?
I imagine your method isnt getting hit because the url is incorrect. Grab fiddler*, and take a look at the acutal http traffic and see if it is 404'ing on the request.
*(once fiddler is running change your url to http://localhost:port/..... to http://localhost.:port/.....)
I guess you could modify the "index" method inorder to get the data from "GetJSon" method something like below.
public ActionResult Index()
{
return View("GetJson");
}
Hope this helps!!
I want to insert data into SQL Server database when I click "Insert" button in excel.
The data is in Cells A2 and B2 and here is the code behind the "Insert" button in excel:
Dim HttpReq As New WinHttp.WinHttpRequest
HttpReq.Open "POST", "http://localhost:11121/Student/Insert/", False
HttpReq.Send "jsmith112"
Here is my code for the Controller action in VS:
[HttpPost]
public ActionResult Insert(string id)
{
try
{
student.AddToStudents(id);
student.SaveChanges();
return RedirectToAction("Index");
}
catch
{
return View();
}
}
This doesn't seem to be working, could anyone guide me into finishing this?
Thanks in advance
Just change the POST to
"http://localhost:11121/Student/Insert/" + id
and then map the route
routes.MapRoute(
"InsertStudent",
"Student/Insert/{id}",
new { controller = "Student", action = "Insert", id = "" }
);
and then in your controller you can check if id is empty, if not then make a new user
also, sometimes I do things like this
routes.MapRoute(
"Resource",
"{resource}/{operation}/{id}",
new { controller = "Resource", action = "Index", resource = "", operation = "" id = "" }
);
and then you could parse out what the things are..
as a side note and if you were making more end points for your service, you might consider using GET, POST, PUT, DELETE instead of actually having "Insert" in the URI. REST.
I don't think your controller action would see the data in this case. It has no way of knowing that the 'jsmith112' you sent should correspond to the string id parameter. Inside of your controller action, use the Request.InputStream object to grab the posted data and send that into the database.
A better way to do this would be to either send it through as url-encoded form data (so the post body would be 'id=jsmith112'), or to change the request to a GET (or a PUT, if you want to be properly RESTful) and hit this URL:
http://localhost:11121/Student/Insert/jsmith112
In that case it should be picked up by the string id parameter.
Also, put a breakpoint inside the controller action to be sure you're actually hitting it, then use the debugger to verify your web service has the data it needs.
I have a requirement to add specific functionality to an asp.net mvc2 web site to provide addtional SEO capability, as follows:
The incoming URL is plain text, perhaps a containing a sentence as follows
"http://somesite.com/welcome-to-our-web-site" or
"http://somesite.com/cool things/check-out-this-awesome-video"
In the MVC pipeline, I would like to take this URL, strip off the website name, look up the remaining portion in a database table and call an appropriate controller/view based on the content of the data in the table. All controllers will simply take a single parameter bieng the unique id from the lookup table. A different controller may be used depnding on different urls, but this must be derieved from the database.
If the url cannot be resolved a 404 error needs to be provided, if the url is found but obsolete then a 302 redirect needs to be provided.
Where the url is resolved it must be retained in the browser address bar.
I have had a look at the routing model, and custom routing and can't quite work out how to do it using these, as the controller would not be predefined, based on a simple route. I am also unsure of what to do to provide 404, 302 back to the headers also. Perhpas I need a custom httpmodule or similar but going there went beyond my understanding.
This must be possible somehow... we did it years ago in Classic ASP. Can anyone help with some details on how to achieve this?
Well, the simplest way would be to have an id somewhere in the url (usually the first option)
routes.MapRoute(
"SEORoute", // Route name
"{id}/{*seostuff}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional, seostuff = UrlParameter.Optional } // Parameter defaults
);
In your controller you'd have something like
public class HomeController {
public ActionResult Index(int id) {
//check database for id
if(id_exists) {
return new RedirectResult("whereever you want to redirect", true);
} else {
return new HttpNotFoundResult();
}
}
}
If you don't want to use the id method you could do something else like...
routes.MapRoute(
"SEORoute", // Route name
"{category}/{page_name}", // URL with parameters
new { controller = "Home", action = "Index", category = UrlParameter.Optional, pagename = UrlParameter.Optional } // Parameter defaults
);
public ActionResult Index(string category, string page_name) {
//same as before but instead of looking for id look for pagename
}
The problem with the latter is that you would need to account for all types of routes and it can get really difficult if you have a lot of parameters that match various types.
This should get you in the right direction. If you neeed some clarification let me know and I'll see if I can write a specific route to help you

You could probably do what you're looking for like
public ActionResult Index() {
//Create and instance of the new controlle ryou want to handle this request
SomeController controller = new SomeController();
controller.ControllerContext = this.ControllerContext;
return controller.YourControllerAction();
}
but I don't know any of the side effects by doing that...so it's probably not a good idea - but it seems to work.
How do i map multiple url's to the same action in asp.net mvc
I have:
string url1 = "Help/Me";
string url2 = "Help/Me/Now";
string url3 = "Help/Polemus";
string url1 = "Help/Polemus/Tomorow";
In my global.asax.cs file i want to map all those url to the following action:
public class PageController : Controller
{
[HttpGet]
public ActionResult Index()
{
return View();
}
}
Now in MVC 5 this can be achieved by using Route Attribute.
[Route("Help/Me")]
[Route("Help/Me/Now")]
[Route("Help/Polemus")]
[Route("Help/Polemus/Tomorow")]
public ActionResult Index()
{
return View();
}
Add the following line to your routing table:
routes.MapRoute("RouteName", "Help/{Thing}/{OtherThing}", new { controller = "Page" });
EDIT:
foreach(string url in urls)
routes.MapRoute("RouteName-" + url, url, new { controller = "Page", action = "Index" });
In my case I was looking to simply combine two 'hardcoded' routes into one and stumbled upon this post. I wanted to clean out my RouteConfig.cs a little - because it had so many similar routes.
I ended up using some simple 'or' logic in a regular expression and basically changed:
routes.MapRoute(
"UniqueHomePage",
"Default",
new { controller = "Redirector", action = "RedirectToRoot" }
);
routes.MapRoute(
"UniqueHomePage2",
"Home",
new { controller = "Redirector", action = "RedirectToRoot" }
);
Into a single route:
routes.MapRoute(
"UniqueHomePageGeneric",
"{url}",
new { controller = "Redirector", action = "RedirectToRoot" },
new { url = "Home|Default" }
);
Note for the SEO-savy or -interested: The reason for pointing multiple URL's to one and the same action, is to then redirect them to one and the same page again. In this case the homepage. So the idea is to prevent duplicate content issues. When you use this method for pointing for NON redirecting actions, but actions that show their own views, then you might be CAUSING duplicate content issues :P.
You can just add the routes into your route table as you need them, same as any other route. Just give them unique names, hard coded URL and point them to the same controller / action. It will work fine.
If you use pattern matching instead of hard coded URLs just make sure you get all your routes in the right order so the correct one is selected from the list. So /Help/Me should appear before /Help/{Page} if the hard coded route goes to a different page to the pattern matched one. If you put /help/{page} in the route tabel 1st this will match to /help/me and your hard coded named action for that route would never fire.
On a side note, if this is a public facing site and SEO is important please be careful if you have multiple URLs returning the same data, it will be flagged as duplicate. If this is the case, then use the Canonical tag, this gives all the page rank from all the URLS that go to that single page to the one you name and removes the duplicate content issue for you.
