Handle Optional Parameters In URL Routing?

Jun 2, 2010

I've already implemented URL routing in my app but there are cases where I may or may not get a paramter. In particular, I'm trying to come up with a good way to handle multi-language support. For example, if my regular URL is /SomeCategory/Friendly-Topic-URL, I want to have an optional language selector at the end but I'd like to be optional. So, if I get /SomeCategory/Friendly-Topic-URL/es, that should bring up the topic in Spanish but if get nothing, that should bring up English.

Iis7 Url Rewrite - Optional Querystring Parameters?

Mar 9, 2010

I'm using the iis7 URL Rewrite module and it's working fine, except for two things. Being new to this, I might be missing something obvious.

1) My URL gets converted from www.mysite.com/search.aspx?fName=John&sName=Smith to www.mysite.com/John/Smith. This works fine, but if I add a trailing / , a few images on the site disappear, wheras a few don't. (They're all in the same location). However, the search results are fine.

2) Is it possible to make cerain querystrings optional? Server side, this is implemented (i.e. if nothing is entered, then assume a default value). But how would this work with the URL rewrite module? e.g. www.mysite.com/John would search for John and use a default value for the sName parameter.

Pass Optional Parameters Into A WebMethod Via JSON?

Feb 15, 2010

I have the following JSON class I am intending to use to perform management calls on my database asynchronously:

<script type="text/javascript">
var CalendarManager = {
defaultOptions: {
staffcode: 0, // required
date: 0, // required

[Code]....

Basically, my question is: how do I specify optional parameters to a WebMethod when providing JSON data?

I know I can reduce the parameters down to just the required values, and then use HttpContext.Request.Params to read the values of optional paramaters, but I would have thought the way I have tried here should have worked.

EDIT

The XMLHttpRequest.responseText value for the error is:

Invalid JSON primitive: staffcode.

This is throwing me even more off the scent of the problem :(

Access :: Parameterized Queries With Optional Parameters (Access DB)?

Aug 13, 2010

so I have a web programming assignment for university where I'm building a website that uses an Access database but I have hit a brick wall with something.I'm using parameterized queries to query my database. For one of my queries, I want to be able to take a bunch of parameters that are optional, and if they aren't needed I'll pass in a value of null and I'd like the part of the where clause relevant to them to evaluate to true. This is straightforward in most databases, from my understanding you could do something like to make param1 an optional parameter.

WHERE ((@param1 = ARandomColumnName) OR (@param1 = null))

However this can't be done using Access, as all parameters in a query are represented by a ?. Every ? is assumed to refer to a different parameter, so if you want to use a parameter more than one (like the above code I wrote does) then you'd have to pass it twice. This seems hacky to meSo what do I do? I have spent *hours* googling and banging my head on the desk. I'll cry if I missed something really obvious

WCF / ASMX :: Too Many Parameters 400 Bad Request Error

Dec 23, 2010

I created a WCF. The web.config is as follows,

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.web>
<compilation debug="true" />
</system.web>
<system.serviceModel>
</system.serviceModel>
<system.webServer>
<directoryBrowse enabled="true" />
</system.webServer>
</configuration>
The following can be seen in the service.svc file,
class AppServiceHostFactory : ServiceHostFactory
{
protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
{
return new WebServiceHost2(serviceType, true, baseAddresses);
}
}
This is the method in the service.svc.cs,
[WebHelp(Comment="Sample description for GetData")]
[WebGet(UriTemplate="/GetData/param1/{i}/param2/{s}")]
[OperationContract]
public SampleResponseBody GetData(string i, string s)
{
// TODO: Change the sample implementation here
// if (i < 0) throw new WebProtocolException(HttpStatusCode.BadRequest, "param1 cannot be negative", null);
return new SampleResponseBody()
{
Value = String.Format("Sample GetData response: '{0}', '{1}'", i, s)
};
}

The following is the webservice url. It returns data if it's run through the asp.net engine but throws bad request when run from IIS. I added the following entry in the web.config but no use. it still fails.

WCF / ASMX :: How To Pass The Parameters Into Webservice Method

Jan 4, 2011

i am working in the webservice project. I have one project when i run it then shows the text box for parameters and return the result after passing the parameters.

But another webservice does not allow me to enter the paramerters when execute then list of methods displayed and then show the soap xml when click at any method.

what difference found in both webserivces are Excuting-one that have the Text boxes: Test: "To test the operation using the HTTP POST protocol, click the 'Invoke' button."

2nd One Not provide the parameter text boxes: Test: "The test form is only available for methods with primitive types as parameters"

Dont know how to fix that. Because i want to debug the webservice and as i am unable to provide the parameter then how can i fix it.

how can i pass the parameters in the 2nd webservice as it has different information mentioned above.

WCF / ASMX :: Webservice Custom Objects As Input Parameters?

Nov 9, 2010

I have a fundamental question to ask about web services. I'm currently writing a service that has custom classes (lots of them). Let's say a car is one example. For some reason I was thinking that the service should expose these objects. However once I created a site to consume the service, it looks as though the classes are not meant to be exposed. It looks like the best practice is to take in a string which may be xml or not and convert that string into the object in the service code.(especially for error handling or input validation)

For example, if I had the web method:

[WebMethod]
public car getCar(int carId)
{
//code here to return car object
}

This will take a car ID and return a car object. It also shows all the elements in the SOAP request and response objects (as well as the WSDL) which can be to external developers. However, when trying to consume the service from a website (or reference it in my code), I then need access to the Car class (which implies i need to expose it through the services as well?).

WCF / ASMX :: Access/pass Parameters To A Web Service WITHOUT A (general) Form?

May 15, 2010

I am a newbie to ASP.NET (but not to C#)I have a project I am developing that may seem unconventional at this point but it is a project that I hope to eventually expand and provide a new type of service on the internet. Currently the project makes use of an Excel spreadsheet that is generated by another application I wrote. Basically the spreadsheet is an index to a specific type of file that exists on a host computer and the files are directly linked from within the excel document. When the link is clicked it opens the file using the operating system default program which then processes the file (this takes some time).

This is fine and dandy but when I click on another file, the default program immediately stops processing one file and opens the latest submission and thus interrupting the previous job. To prevent this I am now writing a queuing application. Here is where ASP.NET comes in. I do not want the link to open the queuing application with the file to add into the queue as a parameter because that pops one or more nnoying/scary "you are opening an executable" dialogs and because I want to be able to access the queuing service from a remote computer, and possibily in the future over the web. Instead I am trying to use an ASP.NET service application that will accept the name of a file as a parameter, access the external queue class (defined in an external dll of which only one universal instance is allowed), and add the request to the queue. Whether or not the table is an excel table or on a web page, using a form in this instance is tedious, not only for me but for a user. I want the user to be able to simply click on an html link and have the file be queued without anything except maybe a confirmation page pop up saying that the file has been queued and it will take x amount of time before the file is finished processing.

My problem is I cannot for the life of me find a way to do this. I have searched the interenet for over a week now looking for a way to call a "WebMethod" using a link and I am getting the impression that it cannot be done. Even when I use a form and try to have the form pass a string (representing the file name) as its "action" it comes up with an application error saying that I am missing the parameter I am trying to pass. Here are some examples of what I have tried:Here an example method I would try to access:

Here is an example of how I tried to access directly by way of a link (which results in an application error: InvalidOperationException)"
