Hello to all developers,
I am trying to find some example of Dynamically generate URL(PURL).
I have seen one software which generate personalised URL from MySQL database .
The only thing is that software is using PHP to generate URL and as a .NET developer I dont know about php.
My question is is there a way that I can fetch data from data base and using perticular field i can generate url which is not actually store in my web space..
eeg.
-----database-----
firstname | lastname ....
===========================
xyz abc
pqwert qweoiuy
alfa beta
the URL should be like
http://something.com/somepersonal/xyz_abc.aspx
http://something.com/somepersonal/pqwert_qweoiuy.aspx
http://something.com/somepersonal/alfa_beta.aspx
It is something like personalised page for users or clients.
I have template to use as back page but dont know how to plug and dynamically generate URL..
You're thinking of this a little backward. Generally, one wouldn't do this by generating it directly from the database. You would generally do this by routing the url batch /somepersonal/ to some personalpage control, which would then consider everything after it, like xyz_abc to be an argument. Personalpage would then use that argument to customize its display, be it from the database or wherever.
So to clarify, your URL would look something like:
http://something.com/personal/vish_soni
http://something.com/personal/colonel_gentleman
http://something.com/personal/general_specific
But all of these are being routed to Personalpage, which then uses vish_soni, colonel_gentleman, and general_specific as arguments to query the database or do whatever else it needs to do.
Microsoft has an overview of this pattern and routing in general here.
You can create a controller class and call an action method. For your case, you just need to send parameter and then lookup customer info to prepare the content.
public class HomeController : Controller
{
public ActionResult Me(string id)
{
ViewBag.Message = "Welcome to ASP.NET MVC! "+id;
var contentobj = repository.GetUSerContent(id);
return View("Index",contentobj);
}
}

I'm not sure of the best way to accomplish my goal. Looking for insight. I'm familiar with WebAPI services consumed through WPF and Silverlight but this is my first run at ASP and MVC.
I am building a site to verify contents of a shipment against an electronic manifest (EDI 856). I have a page that displays the shipping data and I need the users to scan each item barcode in the container. I would then like to pass that barcode to a service, verify the item belongs in that shipment and then update the page to show as much.
My plan was to have a single text box into which the user could scan/type the barcode and then submit that data to a WebAPI service which would verify the information and then probably use SignalR to send a message back to the page and update a grid with the item data.
If this is a decent way to go, I'm just not quite sure how to use ajax to call the WebAPI endpoint and provide the data I need.
I would advise against using SignalR in this situtation. What you need, judging from your description, is the most basic use case of submitting an ajax request and receiving a response.
You are not designing a system where you need the server to initiate communication with the browser or anything like that, where sockets (and SignalR as an abstraction over sockets with fallbacks to less suitable protocols) is a huge overkill.
Don't worry, your use case is rather simple.
It's a little out of scope to describe how to setup a WebApi project, how to configure routing, action names, etc. Simple google searches will surely provide ample quality tutorials on getting started.
I'll just try to explain what the general idea is, with some code samples, to get you thinking in the right direction.
You need to create an ApiController.
The simplest version of that Controller will probably look something like this:
public class ShipmentVerificationController : ApiController
{
//this is the response object you will be sending back to the client website
public class VerificationResult
{
public bool Valid;
}
public VerificationResult GetIsItemValid(string BarCode)
{
bool itemIsValid;
// Implement checks against the BarCode string here
itemIsValid = true;
return new VerificationResult { Valid = itemIsValid };
}
}
Note that the inner class represents the response you will be sending back. It should be properly filled out with additional info if needed and probably put into a separate .cs file in the "Models" folder or where ever you see fit.
I have declared it inside the controller for demonstration purposes only
Once you have a WebApi service deployed, it's really easy to send it data from your website and receive the feedback.
To simplify Ajax requests, jQuery is often used.
Once the user inputs the barcode into a textbox, you can hook up an event to check for return key being pressed (most barcode scanners send the return key command after they input the barcode data) and then write something along the lines of:
var barcode = $("#input-field").val();
$.getJSON( "<url_to_your_webapi_service>/api/ShipmentVerification/GetIsItemValid/" + barcode, function( data ) {
if (data.Valid) {
// great, highlight the item as valid
}
else {
//better indicate an error with the scanned item
}
});
Please note that for simplicity I have not included any error handling, url parameter encoding, and most importantly, zero authorization.
Authorization is very important if you deploy the web service to the open web but still do not want anyone to be able to call it.
You will have to research these topics yourself, but I hope I have presented you the core concepts and logic behind a simple service such as this, so you have a base to start with.
If you come up with specific problems and questions post a new question.
I actually found a more simple way to do this. I nixed the idea of using a WebAPI endpoint and just went with a normal controller. I used ajax to prevent the page from refreshing with the new view, since that view is actually just json data with my return values in it.
I am working on one application it's like twitter.
So how can I accomplish the url such as,
twitter.com/username
This will open profile related to username.
I am creating using asp.net.
Thank you
If you are planning on using MVC Razor, it will be as simple as passing a query string parameter to your page. For example:
public ActionResult Index(string name)
{
//Get user information and pass to view
User userDetails = SomeLogic.GetUser(name);
return View(userDetails);
}
Or, if using ASP.NET Web Forms you will have to use Friendly URL's by adding a Nuget package. Tutorial can be found here: http://blogs.technet.com/b/southasiamvp/archive/2014/03/31/guest-post-exploring-asp-net-friendlyurls.aspx
In the grand scheme of things, all you need to do is pass a query string parameter to your page. Using the friendly URL's will help you accomplish the URL format you require.
Update
From your comment, I see you are using Web Forms, so I will modify the answer on getting a query string value. The code below won't render URL in a friendly format, but I am hoping you will then be able to modify the example based on the link I provided above.
protected void Page_Load(object sender, EventArgs e)
{
if (Request.QueryString["name"] != null && !String.IsNullOrEmpty(Request.QueryString["name"].ToString())
{
string myNameValue = Request.QueryString["name"].ToString();
//Since you have the name in the querystring, pass value to method that retrieves the record
User userDetails = SomeLogic.GetUser(name);
}
}
So the URL will be: profile.com/profile.aspx?name=John.
But as I stated, you will need to modify the code to change the example to use Friendly URL's, that can be found in this tutorial: http://blogs.technet.com/b/southasiamvp/archive/2014/03/31/guest-post-exploring-asp-net-friendlyurls.aspx
I am seeking help in setup an application so that I can give my clients their own url for browsing.
I am thinking about creating asp.net MVC application and by using AREAS feature ( I will consider each area as my client) I will develop individual application for my client and provide them the url which will serve a their own application running.
Basically, I want to keep my all clients in one application but give them different url.
As areas works as follows:
localhost:5699 -- it will land to default home controller and index page
ocalhost:5699/area1/home/index - it lands to Home controller or Area and renders index view of this area
and so on for another area.
So. I want to ask, can i use this approach to give my clients unique url which I can map to particular Area of application and client can browse simple typing their url and that land to index page of that area?
for example:
www.area1.com -- I want to map this url to localhost/5699/area1/home/index.aspx
www.area2.com -- I want to map this url to localhost/5699/area2/home/index.aspx
Please help, how can i will setup all above in production and development environment
Basically, i want to setup my application such that if my client want different UI and additional functionality I can easily alter respective controller.
If I understand the question correctly, I think you can accomplish your goal by way of the Route and RoutePrefix attributes. These attributes will decorate controllers and methods and give you the ability to tweak the URL's exactly how you want it.
localhost/5699/area1/home/index
[RoutePrefix("area1")]
public class Area1Controller: ApiController
{
[Route("home/index")]
public ActionResult Index()
{
// controller logic here
}
}
localhost/5699/area2/home/index
[RoutePrefix("area2")]
public class Area2Controller: ApiController
{
[Route("home/index")]
public ActionResult Index()
{
// controller logic here
}
}
Currently trying to augment the search of an existing ASP.NET site. My background is Java, so if I was writing a server in Java, I could just handle the incoming request as a string and parse it however I wanted, taking out the search terms, etc.
What part of ASP handles that? Where should I be looking for where the incoming string is taken apart to handle the search request? There is a search button which redirects the page to a URL which includes the search parameters. That's where the trail goes cold for me as I need to know where it comes back into the server.
For example, once you've vetted the search term it gets submitted like this:
Response.Redirect("~/shop?" + type + "=" + searchBoxContent);
'type' is the type of search so that could be based on brand or searching within the product description, etc.
The site is already using some type of url rewriting as the url doesn't show up with any .aspx when you do a search. Should I be looking in a config file or a .master.cs file or where to point me in the right direction?
The easiest system for this is ASP.NET MVC which has a built-in Route and parameter handler.
See MSDN for docs.
Example:
{controller}/{action}/{id}
Can redirect to a Controller action:
public ActionResult Find(int id)
{ ... }
If this is not what you want, take a look at this blog article of Scott Guthrie on URL rewriting.
If you have a URL like this:
/shop.aspx?type=abc
then you can use Request.QueryString the get the value of type. This is the syntax:
Request.QueryString["type"]
For example if you want to get the value when /shop.aspx?type=abc is loaded at the first time, then you should add this code in Page_Load method inside the code behind (shop.aspx.cs):
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
// assign 'type' query string to typeOfSearch
string typeOfSearch = Request.QueryString["type"];
}
}
If I navigate to the following stackoverflow URL http://stackoverflow.com/questions/15532493 it is automatically appended with the title of the question like so:
http://stackoverflow.com/questions/15532493/mvc-custom-route-gives-404
That is, I can type the URL into my browser without the question title and it is appended automatically.
How would I go about achieving the same result in my application? (Note: I am aware that the question title doesn't affect the page that is rendered).
I have a controller called Users with an action method called Details. I have the following route defined:
routes.MapRoute("UserRoute",
"Users/{*domain}",
new { controller = "User", action = "Details" },
new { action = "^Details$" });
As this is an intranet application the user is authenticated against their Windows account. I want to append the domain and user name to the URL.
If I generate the URL in the view like so:
#Html.ActionLink("Model.UserName", "Details", "User", new { domain = Model.Identity.Replace("\\", "/") })
I get a URL that look like this:
Domain/Users/ACME/jsmith
However, if the user navigates to the URL Domain/Users/ by using the browsers navigation bar it matches the route and the user is taken to the user details page. I would like to append the ACME/jsmith/ onto the URL in this case.
The research I have done so far indicates I might have to implement a custom route object by deriving from RouteBase and implementing the GetRouteData and GetVirtualPath methods but I do not know where to start with this (the msdn documentaiton is very thin).
So what I would like to know is:
Is there a way of achieving this without implementing a custom route?
If not, does anyone know of any good resources to get me started implementing a custom route?
If a custom route implementation is required, how does it get at the information which presumably has to be loaded from the database? Is it OK to have a service make database calls in a route (which seems wrong to me) or can the information be passed to the route by the MVC framework?
It's actually pretty simple. Since the title is just there for SEO reasons you do not need to get to the actual question, so the Question controller (in SO case) will load the correct question based on the id (in the URL) and redirect the user with a 301 status code.
You can see this behavior with any web inspector
You could do it client-side with Javascript:
history.pushState({}, /* Title Here */, /* URL Here */ );
Only downside is not all browsers support it.
