How may I post arbitrary data to a REST WCF webservice? I mean, wihout use contracts.
Because my data is dynamic and I cannot have contracts, I want to get ride of the serialization overhead.
How should I declare my service and method?

what is the equivalent of stringbuilder in android??
in android i use

Is it possible to create REST based web service using asmx?
View 1 RepliesI 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

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 am trying to post data from vb.net application to web service asmx that is located on server! For posting data from vb.net application I am using this code:
Public Function Post(ByVal url As String, ByVal data As String) As String
Dim vystup As String = Nothing
Try
'Our postvars
Dim buffer As Byte() = Encoding.ASCII.GetBytes(data)
'Initialisation, we use localhost, change if appliable
Dim WebReq As HttpWebRequest = DirectCast(WebRequest.Create(url), HttpWebRequest)
'Our method is post, otherwise the buffer (postvars) would be useless
WebReq.Method = "POST"
'We use form contentType, for the postvars.
WebReq.ContentType = "application/x-www-form-urlencoded"
'The length of the buffer (postvars) is used as contentlength.
WebReq.ContentLength = buffer.Length
'We open a stream for writing the postvars
Dim PostData As Stream = WebReq.GetRequestStream()
'Now we write, and afterwards, we close. Closing is always important!
PostData.Write(buffer, 0, buffer.Length)
PostData.Close()
'Get the response handle, we have no true response yet!
Dim WebResp As HttpWebResponse = DirectCast(WebReq.GetResponse(), HttpWebResponse)
'Let's show some information about the response
Console.WriteLine(WebResp.StatusCode)
Console.WriteLine(WebResp.Server)
'Now, we read the response (the string), and output it.
Dim Answer As Stream = WebResp.GetResponseStream()
Dim _Answer As New StreamReader(Answer)
'Congratulations, you just requested your first POST page, you
'can now start logging into most login forms, with your application

I have developed an rest enable wcf service by using the following link

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 ?

My web service uses .Net Framework 2.0. An e-learning application reads and updates an Access database in the web service via Http Post commands. I test the e-learning application and the web service using the version of IIS 7 that came with Windows Vista. I run IIS using localhost in my browser.
All works well. But a friend is having trouble running the same test with my files on her IIS 6 server. So I'm developing a checklist of issues in setting up an IIS 6 server to run a web service. I plan to include all possible causes of problems including permissions, accounts that are needed, etc. Are there resources to which I can go for this checklist?
we need to expose a web service to the 3rd party vendor which can only call using POST protocol, NOT SOAP.So my question, is it better to build a web service or just simply .aspx page?Also is there any best practice documentation on this.
View 4 RepliesI can't seem to call a web service method from Ajax with both POST and GET.
Initially only the POST would work and GET would causes this error:
{"Message":"An attempt was made to call the method u0027getDatau0027 using a GET request, which is not allowed.","StackTrace":" at System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData methodData, HttpContext context)at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext
context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}
I fixed that by adding this attribute: [ScriptMethod(UseHttpGet=true)] but now GET causes this error:

So is it true that you can only use either POST or GET and not both from Ajax?
how to post the SAML Response in an HTML form to the assertion consumer service.
I have generated the saml reponse and want to send the same to the re-directing url.
We have an existing, proprietary data processing application that runs on one of our servers and we wish to expose it as a web service for our clients to submit jobs remotely. In essence, the system takes a set of configuration parameters and one or more data files (the number of files depends on the particular configuration template, but the normal config is 2 files). The application then takes the input files, processes them, and outputs a single result data file (all files are delimited text / CSV or tab).
We want to now expose this process as a service. Based on our current setup and existing platforms, we are fairly confident that we want to go with WCF 4.0 as the framework and likely REST for the service format, though a SOAP implementation may be required at some point.
Although I am doing a lot of reading on SOA, WCF and REST, I am interested in other thoughts on how to model this service. In particular, the one-to-many relationship of job to required files for input. It seems pretty trivial to model a "job" in REST with the standard CRUD commands. However, the predefined "job type" parameter defines the number of files that must be included. A job type of "A" might call for two input files, while "B" requires 3 before the job can run.
Given that, what is best way to model the job? Do I include the multiple files in the initial creation of the job? Do I create a job and then have an "addFile" method where by I can then upload the necessary number of files?
The jobs will then have to run asynchronously because they can take time. Once complete, is it best to then just have a status field in the job object and require the client to regularly query the system for job status, or perhaps have the client provide a URL to "ping" when the job is complete?
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
[Code]....
Update: forgot to mention i even tried decorating the operation with WebGet attribute with UriTemplate parameter, without luck.
I am a REST web service newbie, does visual studio, .NET, or some other nifty microsoft tool provide any easy way to auto generate classes to consume a REST web service? With REST services is there even a service definition like there is with SOAP (WSDL) beyond the printed documentation? There is a new service that I'd like to consume but they only wrote wrappers for PHP, Pearl, Ruby, and Java and have more or less said you are on your own with .NET. I could write it myself but I'd like to cut corners and save time wherever possible.

I am trying to interface a website we have with our helpdesk software. The helpdesk software has a REST API that i can connect to. So far I have been successful in getting a current ticket with the following code.
[Code]....
[URL] How would I implement this in ASP.Net? I want to create the ticket, and need to be able to retrieve the access key that it returns. I tried using the same code above, but instead changing the method string to this.

But I get a "Bad Request" error from it.
I'm investigating creating a WCF REST service for an existing asp.net application to be consumed by various clients including Windows Phone 7, Android, iPhone apps etc.Creating a simple WCF REST service and consuming it from the above platforms is not a problem and works really well. What I am struggling to get my head around is authorization.The asp.net application uses the Membership provider to provide authentication and authorization and I'm comfortable in using that API from the REST service.
How do I secure my REST service so that the first call has to be to authenticate (passing the username and password) and following calls know who is 'logged in'. I'm guessing the authenticate method will have to pass back some sort of token to be used in subsequent calls identifying the caller. Is this secure enough as the whole site / service is over SSL?
Trying to deploy a wcf rest service inside of an asp.net web application. Works wonderfully when deploying to test server in visual studio, however when i deploy to iis 6 I get nothing. It is as if my service is not there at all.
here is my web config under system.service model:
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
and im registering a route in the global.cs
routes.Add(new ServiceRoute("Service", new WebServiceHostFactory3(), typeof(WcfJQueryService)));
my web service class is decorated with:
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
I am using windows authentication if that matters in this case.
I made a simple WCF web-service inside an ASP.net website.
The web-service is hosted by IIS and works fine on localhost, ie when accessing for exemple to
[URL] I get the correct "Hello World" response as expected.
But accessing to it by my computer hostname [URL] gets me an error 404 response. This is particularly confusing as the remaining of the site (mainly aspx pages) is accessible without any problem from both ways.

I have a WCF REST service built with C# and it returns an image as part of a CPU intensive operation. The client is running on Android (Java) By default, it will return a text JSON object that looks something like this:
{"d",[9,0,77,12,11,...]}
Those are they bytes of the image. Fine. However, all the solutions for decoding this JSON are intolerably slow. I've tried Gson, Jackson, and the built-in Android JSONObject class. I have no idea why they are so slow.
As an alternative solution, I have my REST service return a GUID, and then that GUID can be used by the Android client to go to a regular URL that serves up the image as a regular binary stream, via an MVC controller.
This works well, and it fast, and is pretty easy to handle on the Android side. However, it does feel like a bit of kludge and kind of a violation of the REST design principles. Am I missing something here? Is there a better way to do this?
I am attempting to parse the XML output from a REST web service and have been pointed in the direction of using Linq2Xml to query the XML for the attributes that I am after. The XML output is as follows:
<?xml version="1.0" encoding="UTF-8"standalone="yes" ?>
<Response Status="OK">
<Item Name="NumberZones">2</Item>
[code]...
The returned datatable is empty, I have confirmed that result does have the XML assigned, and result.value is the string version of the XML file (200Westralia0{81C56183-31DA-45C2-90C3-81609F01B38B}Lounge10001{eac0109e-0090-a992-7fba-dc67fe29e6e7})Is anyone able to provide assistance in how I can read from the REST XML example above the name (ZoneName%) and the attribute value (Westralia and Lounge)?
