what exactly happens with http and soap in web services.I was going through http://vijaybalajithecitizen.blogspot.com/2008/11/aspnet-web-services-interview-questions.html,it describes the soap but what about http, what are the relationship between them.When I call a webmethod from a asp.net application , is it a sopa/http call...how does it return value.
How to detect if it is a soap/http call?
ASP.Net 2.0 Web Services automatically create both SOAP 1.1 and SOAP 1.2 bindings. Our web service, however, has SOAP extensions and custom exception handling that make the assumption that only the SOAP 1.1 binding is used (for example, the SOAP extension uses the HTTP SOAPAction header to control behavior).
I am looking to correct the code that makes these assumptions and make it work with either SOAP 1.1 or SOAP 1.2 properly. I am running into a bit of a problem in the generation of elements for our SOAP faults.
Consider the following web method implementation:
[Code]....
The SOAP 1.2 response now has the wrong qualified name for the detail element. It should be <soap:Detail>, but instead is merely <detail>, same as the SOAP 1.1 response.
It seems that the ASP.Net 2.0 framework has done quite a bit to transform a SOAPException into the appropriate form for the SOAP version, but neglected to properly handle the detail element. Additionally, they don't seem to have exposed the correct SOAP 1.2 qualified name for the detail element as was done with the SoapException.DetailElementName property.
So, what is the correct way to add a detail element to a SOAP fault response that works for both SOAP 1.1 and SOAP 1.2? Do I need to detect the SOAP version myself and hard-code the SOAP 1.2 qualified name for the detail element?
when I access the webservices URL through browser ,I am able to access the URL ,If i use the webmethod in c# code the error message is diplaying like "The Requested Failed with HTTP Status 404:Not found".
View 5 RepliesI there a way to know if a request is a soap request on AuthenticateRequest event for HttpApplication? Checking ServerVariables["HTTP_SOAPACTION"] seems to not be working all the time.
public void Init(HttpApplication context) {
context.AuthenticateRequest += new EventHandler(AuthenticateRequest);
}
protected void AuthenticateRequest(object sender, EventArgs e) {
app = sender as HttpApplication;
if (app.Request.ServerVariables["HTTP_SOAPACTION"] != null) {
// a few requests do not enter here, but my webservice class still executing
// ...
}
}
I have disabled HTTP POST and HTTP GET for webservices in my web.config file.
<webServices>
<protocols>
<remove name="HttpGet" />
<remove name="HttpPost" />
<add name="AnyHttpSoap" />
</protocols>
</webServices>
Looking at ContentType for soap+xml only partially solves my problem. For example,
Cache-Control: no-cache
Connection: Keep-Alive
Content-Length: 1131
Content-Type: text/xml
Accept: */*
Accept-Encoding: gzip, deflate
Accept-Language: ro
Host: localhost
mymethod: urn:[URL]
Some clients instead of having the standard header SOAPAction: [URL], have someting like in example above. "mymethod" represents the method in my web service class with [WebMethod] attribute on it and [URL] is the namespace of the webservice. Still the service works perfectly normal. The consumers use different frameworks (NuSOAP from PHP, .NET, Java, etc).
When I use WatiN to go to a specific web page, how can I fake the HTTP referrer with a query string (i.e. request is from google search with query string q=search_term)? So I can verify that the response header has the 301 redirect for specific referrer URL.
View 2 Repliesi redirect a page from http to https using http module begin request handler .i am calling webservice using ajax but it is saying webserice not defined .which otherwise works fineits work fine when rediect page in page_load instead .but i need to add function for https to http in every page. i still not know why ajax is not working when i use http module for redirect

I am working on an asp.net application (.net 4 framework) design and was wanting to know what are the pros and cons and best practices for using webservices vs WCF techology? This application will eventually be used by outside clients to consume data. When would you use WebServices and when would you use WCF? Is one more scalable than the other?

Background:
We are using the Facebook API and receive back URLs for profile image thumbnails. Unfortunately the protocol is restricted to just HTTP and it doesn't support HTTPS. The page on our site that hosts the thumbnails is always delivered via HTTPS, and if we use HTTP for the thumbnails the user will receive security warnings from their browser.
Solution:
Build an HTTP Handler that "passes through" the image from the Facebook URL, but allow the handler to be called via HTTPS. Before I started coding I thought I could something like this:
Response.OutputStream = WebRequest.Create(FacebookUrlForThumbnail)
but I ended up having to save the image to an object in memory than write the image to the Response.OutputStream using the image save function.
Current Code:
[Code]....
This seems inefficient but I can't find a way of using the HTTP Handler as I orginally intended. Is there way of accomplishing the goal without creating the image memory and just "passing through" the call?
I am using webservice and Javascript, and in my javascript function, there's a function called onComplete(data).Now my problem is, I want to get 2 datas instead of one data argument in that oncomplete, is it doable? That "data" is the result of call from my webservice. So I am looking for something like this: onComplete(data1, data2) so that I can display it back to my aspx page
div1.text = data1
div2.text = data2
we consume .net web services in php or not.if yes then please tell me how can we do it. i am to create a web service which takes values and save it in database also it will take values and reply some data as a standard xml format.i know how to create web service and how to use it in asp.net but don't know how to use/call it from php.thing is that i will not be writing code in php to consume but wants to know that do i need to take care of any special thing or need to do some extra code to make it available and use by php developers.

I was wondering what the major differences are between controllers and webservices. I understand webservices can receive postbacks via ajax while controllers cannot. Also, when you put a webservice in a MVC site, what file structure do you use to store it? Just create a single services folder?

Am new bee to Webservices.I have declared complete BLL in the class library.
Can call those methods defined in Class library class files(.cs file) in .asmx file.
We have a web service running on the server. We want to use the service in local machine. Could some one kindly give all the steps to get the methods availble in the client.
We have created web methods in the server. And trying to access the same thing on the client. I can literally access those methods using the refernce variable of the server. but when I try to run it , it comes up with run time exception unable to connect to remote server.
I am developing an ecommerce app that is using the UPS shipping webservice. I have read that it is good to create a singleton so there is only one instance of a webservice at any time. My code for that is below.
[code]...
In the line above in the construtor I have to set the UPSSecurityValue of the service. Then later I will call the ProcessShipment function. My question is; Since the webservice is being traeted as a singlton could different instances of the app share that same UPSSecurityValue and could it change between when I set it and when I call ProcessShipment?
from where to start learning WebServices. I do not know anything about it, i searched internet but no useful sites were found. I am unable to understand almost all the codes written in App_Code/WebService.vb file that is generated in VS.I know some basics of ASP.NET ,VB.NET and C#.NET.

2. I don't have WS access. I just have wsdl alone only. I need to start the paralled development until I get ws access from customer. How to understand the ouput type and....
3. As per my understanding Services are developed using JAX-WS programming APIs.
I believe this ws will return the output as xml.
