how to consume wcf rest services in asp.net MVC? there is any standards are available? in my project SOA, so all the data came from wcf 4.0 rest services if there is any coding examples or resources to consume wcf services in MVC 2.0
View 2 RepliesI have an existing RESTful webservice that I consume (I did not create) from a 3rd party. I currently use WebRequest and WebResponse to create and read the request and response. I access the service by url with query string parameters to pass what type of data I am requesting. I get the results back in XML, then have to load it into a new XmlDocument, create a bunch of DataSets, XmlNodeReaders, DataTables, etc. It's really messy in my opinion.
What I am looking to accomplish is to take advantage of the Entity Framework Model, OData, and WCF. I have never create or used WCF yet. The webservice that I am accessing is some sort of service created from within Apache, it is not .Net. I don't know whether or not I can utilize the new .Net Framework 4.0 services to make the consumption of this service any better, easier, or cleaner.
Why it is not working?
internal static int AddCatalog(string name, Guid key, string userName) {
HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://localhost:25169/ScopraAdminRESTService.svc/");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

I am using the new .NET 4 WCF REST web services. In order to link resources, I'd like to put links in my responses. In ASP.NET I can generate URLs from my routing configuration (e.g. UrlHelper.Action(...))
With WCF REST web services I have an ASP.NET routing configuration plus Uri templates:
[WebGet(UriTemplate = "{id}")]
MyResult Index(string id) {...}
I want to store related URIs in my result objects. How can I construct URLs from my routing configuration + UriTemplates without hardcoding base URLs or other information?
want to use Web Services in a project. I have basic concept of web services but couldn't understand some of its fundamentals.
1. what is SOAP, Rest and JSON ?
2. WCF Services are SOAP based or Rest or JSON based ?
3. Are Ado.net data services different from WCF ?
4. Which Web Services are easy to consume on client side ?
i have a web service project called (WS_Service) i have a html page thats trying to consume WS_Service. i have web services sits on its own project (the reason i have created is because its independednt and can be called from .aspx or .html or mobile) i dont have problem with .aspx and i have just add the reference and fire the services. but i am not sure how i will be doing on .html page below is my code i am trying to POST to a web service:
$.ajax({
type: "POST",
url: [URL] , <<< is that right?
data: "{CustID: " + parseInt(customer_id) + "}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
AjaxSucceeded(msg);
},
error: AjaxFailed
});
I have a build a new 3 tier application (Web,Application,Data tier). The application tier (middle tier) will host wcf web services. I build my service classes, define bindings , contracts etc which does the core business logic, data access and updates.
Now I have around 50 external clients who would want services from my application tier. But my problem is client A might send a flat file request, client B might sends a comma separated file request, client C might be a soap request. The requests further may be either real time or batch. My services may have to send data back to the caller either in a flat file.., xml or a soap response or other formats. The response might also be either batch or real time.
1)Is there a way to standardize the interface for all these 50 clients accessing my WCF services ?
2) If an external client sends a flat file via FTP (intended to serve as input to my service), how do I get this flat file data to hit my service. (Assuming that the legacy system is not service based and hence the external client just sends a file and is not aware of any services of the new system)
I have looked at nearly every single WCF Rest PUT/POST issues on SO here and have still been unable to determine why I am unable to PUT or POST to my web service but am able to call a test GetTime method via GET. This particular service exchanges custom credential information (username, password and some other information) for a token. This token information is encrypted and added to the header of subsequent requests to other web services so that username/passwords don't have to be passed around everywhere. All web service calls are still treated as stateless, but require this auth header information rather username/passwords to access secured service operations.

I have also checked in IIS 7 the handler mappings for *.svc and checked that 'all verbs' are enabled.
I need to call a Rest service but would like to do so without having to redirect. Here is my dilemma. The Rest service we are trying to integrate offers the option to sign up for a subscription but does not allow us to upgrade an existing subscription. So if a user wants to upgrade an existing subscription we have to first cancel and then have the user sign up for a brand new subscription. I don't know how I can make this so it flows nicely in my code. I ideally I would like to do something like this
User decides to upgrade
Click upgrade button
Existing account is being cancelled, if cancellation was successful
New account is being created
How can I do this with a Rest service? Here is a sample URI/URL
https://someservice.com?
Action=CancelSubscriptionAndRefund
&AWSAccessKeyId=AKIAIIFXJCFIHITREP4Q
&CallerReference=CallerReference07
&CancelReason=MyWish
&RefundAmount.CurrencyCode=USD

Could anybody give me some ideas how to make this work in an elegant manner. We thought we could keep the old subscription and then just sign the user up for a new subscription for the difference of the money. For example the first subscription would be 2.95 and the second one would be 2.00 which would amount to a subscription of 4.95. I think it is not elegant and the user would see 2 charges on the credit card, weird, I think. Since I don't know much about Rest maybe there is a way that this can be solved.
I have developed an rest enable wcf service by using the following link
[URL]
Now I want to know is there any difference between rest enabled wcf service (or restful web service) & rest web service ? If there is any difference then what is that ? If there is difference the can you provide me any link (which represents steps visually as in above link) through which I can develop rest web service ?

View 1 RepliesI am using Visual Studio 2010 Release candidate1. I have to deploy my web application which consists of a website, certain window services, certain WCF services and Sql Server 2005 database.I read Vishal Joshi's blog(http://vishaljoshi.blogspot.com/2009/09/overview-post-for-web-deployment-in-vs.html) detaing Web Package in VS2010. I want to know how to deploy window services and WCF services using Web Package. Also, I want to create a web setup (.msi) for deployment instead of Web Package so that the .msi takes care of all the application and database deployment like the web package does.

I would also love to know the way using web services. Which way is more efficient?
View 1 RepliesI have been given some basic documentation of the RazorGator REST API and need to incorporate it into an ASP.NET 3.5 site. I've created my class file to call the API which contains my WebRequest.Create ("URL TO API"). How do I then make the output available so that it can be consumed by other pages? That is, the tickets.aspx page needs to obtain the output results of this API call. What constructs should I use to make this available in tickets.aspx?
Edit
Here's the code I've written thus far:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.IO;
using System.Net;
using System.Text;
namespace SeatEater.Web.UI.search
{
public class RazorGatorService
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://api.razorgator.com/ticketservice/ticets.xml?blahblah") as HttpWebRequest ;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream receiveStream = response.GetResponseStream();
StreamReader readStream = new StreamReader(receiveStream, encode);
response.close();
readStream.close();
}
}
I receive the error message:
A field initializer cannot reference the nonstatic field, method, or property 'field'
in the second line of the above codeblock. I'm very new to using HttpWebRequest and HttpWebResponse. Can you advise me as to how to rectify the error message I'm receiving?
Makes it sense to use ASP.NET applications together with WCF RIA Services or WCF Data Services (to encapsulate the data access layer) ? Or are these technolgies only useful for Silverlight applications.
View 1 RepliesI am facing problem to consume rss feeds, I found several articles on How to consume RSS feeds, they helped me to some extened but I didn't get info for what exactly i am looking. My problem is: I tried to consume feeds from these two [URL]
I've used this code to get the feeds info XmlTextReader readerSport = new XmlTextReader [URL]
DataSet dsSport = new DataSet();
dsSport.Clear();
dsSport.ReadXml(readerSport);
for both the feed dataset have same 8 tables but with diffrent names, and if i write the xml using the folloing code
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load("[URL]");
//xmlDoc.Load("[URL]");
xmlDoc.Save(Server.MapPath("~/sowetan.xml"));
after observing the genrated xml, both the xml have diffrent structure.
1. What information required to display the feed content?
2. if we have diffrent structures for the genrated xml how can we write a single transform method?
3. Is all the 8 tables data required for displayingrss content, In most article i found they've used only for table 3
4. I want to open the feed content on my webpage, how it can be done.
Is there a clean way i can consume WCF RIA Services within an MVC 2 Application?
View 1 RepliesI'm currently working on an ASP.NET Website where I want to retrieve data from an RSS feed. I can easily retrieve the data I want and get it to show in i.e. a Repeater control.My problem is, that the blog (Wordpress) that I'm getting the RSS from uses for linebreaks which I obviously can't use in HTML. I need to replace these with a <br /> tag.
SyndicationFeed myFeed = SyndicationFeed.Load(XmlReader.Create("urltofeed/"));
IEnumerable<SyndicationItem> items = myFeed.Items;
foreach(SyndicationItem item in items)

i have not worked with XML in a while can someone post the syntax needed to build and save an xml node structure that resembles that of a tree structure that is created by a recursive function.
basically i have a recursive function that saves data found an a page(url) and then follows each URL found on that page recursivley and does the same to it. to audit this i want an output as a xml file to disk so i can see how it is doing its recursion and parsing.
the code i have is below. please add to it the needed xml calls needed to create a xml structure like the one i show below. (please include the full name space so i can see where the objects i need in .net are for this.)
page1.htm has 2 links on it:
<a href=page1_1.htm>
<a href=page1_2.htm>
page1_1.htm has 2 links on it
<a href=page1_1_a.htm> (this then will have some links also)
<a href=page1_1_b.htm> (this then will have no more links on it - dead end)
the xml should do something like this:
<node url=page1.htm>
...<node url=page1_1_a.htm>
...... <node url="xxx.htm"/>
...... <node url="yyy.htm".>
... </node>
...<node url=page1_1_b.htm />
</node>

View 1 RepliesI have following service which needs to be consumed in Visual Studio without changing WSDL (as wsdl is third party). It is non compliant WS-I Profile. So it gives error while consuming. Is there any way, I can generate c# class for this WSDL file using another software or commands.

tried so many different things but havent got past this seemingly trivial problem. I created a WCF service application from visual studio 2010 WCF templates. it generated the IService.cs and Service1.svc files and generated the web.config
i created a website in IIS 7 on windows 2008, and pointed it to the app folder. when i go to [URL] via web browser, i get a message indicating service is running and suggests using svcutil etc etc., but when i go to [URL] the web browser says 400 bad request. this is without changing anything from what VS generated. the operation contract looks like

Update: forgot to mention i even tried decorating the operation with WebGet attribute with UriTemplate parameter, without luck.
