I have some issue regarding REST API which i have built using servicestack. End user will consume this API from their application hosted on their server. I'd like to grab absolute uri and IP address from which this REST API being consumed.
When i am doing testing it locally as per below then it gives me URL of REST API itself instead of application from where it is consuming.
string str = RequestContext.AbsoluteUri.ToString();
Please how can i get details about source from where my REST API is consuming.
Thanks in Advance.
I'm not sure I understand this question correctly, do you want the referrer url? or physical location path? Either way the Original ASP.NET request object should have all the information you need which you can access in your webservice with:
var aspnetReq = (HttpRequest)RequestContext.Get<IHttpRequest>().OriginalRequest;
Which you can use to access all information about the request.

When I send a one-off document to RightSignature via their API, I'm specifying a callback location in the XML document as specified in RightSignature's schema definition. I then get a signer-link value back from their API for the document. I display the HTML response from the signer-link URL in an iFrame on our website. When our user signs the document in this iFrame, which is rendering the responses from their website, I want their website to post to our callback location.
Can I do this with the RightSignature API and does it make sense?
So far, I'm only getting content in the iFrame that indicates that the signing was successful. The callback location does not seem to be getting called.
I got it solved just now. Basically, i was doing two things wrong first you have to go in RightSignature Account and set it there the CallBack url
Account > Settings > Advanced Settings
But the thing which RS is unable to mention to us that this url can not be of localhost, but it should be of https i mean like Live URL of your site like
https://stagingmysite.azurewebsites.net/User/CallBackFunction
And then in your CallBack just write these two lines and you will receive complete XML which would have the GUID and document status as well.
byte[] data = Request.BinaryRead(Request.TotalBytes);
string callBackXML = System.Text.Encoding.UTF8.GetString(data);
I found the answer with some help from the API team at RightSignature. I was using callback_location but what I really wanted is redirect_location. Their online documentation was difficult to follow and did not clearly point out the difference.
I got this working after a lot of trial and error.
Is there a way to get the server url (ex: http://www.myapp.com:8080/applicationFolder) without having access to a Request object ?
I need the url at aplication_start and in some classes where the Request object with all the goodies is not available.
note: I know that getting the application folder can be done using
VirtualPathUtility.ToAbsolute("~/");
HttpContext.Current.Request is a static property that always returns the Request object currently executing for the session.
I think all you need a custom solution to know when first request is made after application starts, and then you can send any email you want.. this is the similar problem with solution here http://weblogs.asp.net/reganschroder/archive/2008/07/25/iis7-integrated-mode-request-is-not-available-in-this-context-exception-in-application-start.aspx this do first initialization check in BeginRequest event.
There can be many different addresses all pointing to the same ASP.NET website, like using IP address or name. There might be more than 1 DNS name pointing to the same ASP.NET application. Therefore, HttpApplication, the parent class of Global, does not know which URL a visitor will use. Even IIS doesn't know. Therefore, you have to wait for the first request and then check in the request what URL the visitor uses to access your site. Something like this:
string baseUrl = Context.Request.Url.GetLeftPart(UriPartial.Authority);
One has to use Context to get access to the Request during Global.Application_Start, because Global.Request is not initialised yet.
I have an ASP MVC3 website with a rest API service.
When a user passes in an invalid API or they have been blacklisted i wish to ignore the response.
I know I could send back a 404 or pass back an 503 but if someone keeps polling me then I would ideally like to ignore the response causing a time-out their end. Thus delaying the hammering my server gets.
Is this possible within ASP.net MVC3? If so any help would be most appreciated.
Thank you
For what you want, you still need to parse the request, so it will always consume server resources, specially if you have an annoying user sending a query every 500ms...
In this situations you would block the IP / Header of the request for a period of, for example 10 minutes, but it would be a very good idea to block it on your load balancer and prevent that request that even reach your application, this is easily accomplish if you're using Amazon Services to run your Service, but all other cloud provider do support this as well, if by any means you are using a cloud hosting.
if you can only use your web application, and this is a solution that is not tested, you could add an ignored route to your routing mechanism like:
routes.IgnoreRoute("{*allignore}", new {allignore=#".*\.ignore(/.*)?"});
and upon check that the IP is banned, simple redirect using for example Response.Redirect() to your site, to a .ignore path... or, why not redirecting that request to google.com just for the fun of it?
What is the difference between "Request" and "Response" terminologies in ASP.net?
I am using ASP.net 3.5.
Suppose I have to make somebody understand about these terms. What should i say ?
The Request is what a web client sends to the web server. The Response is what the web server sends - well, in response. Both are defined in the HTTP specification. (How they are structured, what information and meta data they include, etc.)
ASP.Net encapsulates these concepts in respective classes to make them programmatically accessible.
Edit: Specific examples as requested in the comments:
Request.QueryString
If you have a URL like the following:
http://www.host.com/Page.aspx?name=Henry&lastName=Ford
The part after the ? is the query string. (name=Henry&lastName=Ford <= The query string)
This is one common way to pass arguments to the server as part of the Request. In your server code you can access these arguments by using Request.QueryString:
string name = Request.QueryString["name"];
string lastName = Request.QueryString["lastName"];
Response.Redirect
Your server received a Request for a page and you want to redirect to another location. With the Response.Redirect() method, you add a specific piece of information to the Response that causes the browser to immediately go to this other page.
// This tells the browser to load google
Response.Redirect("http://www.google.com");
There is a IIS (Internet Information Services) Server.. In ASP.Net, you can Request for data from the server, and what the server sends you is a Response
I have .net application and I want to ping some webservices and show the status on a webpage.
I tried ping but i am getting "No such host in known".
But the ping works for a url or ip but not working for a service.
Please put ideas here
UPDATE:
I used HttpWebResponse and request. I am getting 401 unauthorized.
Use a head HTTP verb to check. "This method is often used for testing hypertext links for validity, accessibility, and recent modification."
What are you pinging? If you want to check to see if a webservice is there, then just navigate to the full URL of the service and see if you get a page not found or not. In a webpage, you could even get fancy and check it using an ajax request (look up Microsoft.XMLHTTP)
Funny you should ask this because every webservice I have developed, the first method I add to it is ping :) which returns it's state in a one liner that can be displayed on a form.
What if you try to ping the Web Service address instead of the entire End Point? Basically an EndPoint is composed by an Address an a location.Let's suppose you have the following Web Service called CustomerService.svc.
http://myserver.somedomain.com/services/CustomerService.svc
You should try the ping to the address which is myserver.somedomain.com.Also you should consider that some servers have the ping command disabled.
You can download an application such as WCF Storm or SOAP UI that will act as a client to your WCF service. Both have free versions, I believe. They will let you construct an XML request to test the service.
Also, I like to put an actual Ping method in my services that receives an int and returns a string with the same int and a timestamp. It's not strictly necessary, but it helps as a sanity check in a pinch.
