I am making a project where I need to host a simple website. Nancy seems to be a really easy and straightforward library. Only a couple minutes in and I've got a problem no one has addressed online. How do I host an "index.php" file with Nancy?
I'm hosting a *.php file because I need the php script to run on startup, is this even possible with Nancy?
So far all I've got is a "MainModule" class derived from "NancyModule" and it says Get["/"] = p => View["index.php"];. When I navigate to the page however, in my Firefox browser it gives me the error
Nancy.ViewEngines.ViewNotFoundException: Unable to locate view 'index.php
how do I fix this with Nancy or is there any other http web hosting libraries for C# I could use?
After further research I found that Recaptcha has an explicit way to use it. This way allowed me to instead of getting the response through PHP I can get it using Javascript.
var code=document.createElement('p');
code.innerHTML=grecaptcha.getResponse(widgetId1);
document.body.appendChild(code);
I put this code in the action of the form, so when the Recaptcha is solved it will display the response as a paragraph and then it would be obtained using an HtmlParser such as HtmlAgilityPack for C#.

I'm trying to add the ReportExecution2005 Web Service into my project to allow me to execute reports from within my program.
We do this in other programs that are written in VB.net however, these programs have a namespace added for ReportingService that's around 3000 lines of code as the company has always struggled with adding the ReportExecution web service. Before I begin converting this code from VB.net to C# I thought I'd try again in getting it working the proper way.
I'm currently going to the Add Web Reference page, and putting the following:
http://reportserver/Reports/ReportExecution2005.asmx
This is returning a 404 error saying the resource can't be found. I've checked the URL over and over and got colleagues too. So I'm not really sure what else the issue could be.
Is there something that needs adding onto our report server for me to be able to add the web reference?
If anyone has had this issue before how did you solve it?
Any tips appreciated.
I'm having some difficulties with my custom URL-rewriting setup. I'm not using any 3rd party tool to manage this, just using the global.asax by looking at every request and processing it.
The way I am using it is like:
www.mydomain.com/site/google.com
This page contains information about the site "google.com". I'm using the actual domain within the URL. This is all works fine.
I have simplified the code that I'm using just to show you an example of how it works:
Dim myContext As HttpContext = HttpContext.Current
Dim URL As String = myContext.Request.ServerVariables("URL")
If URL.ToLower.Contains("/site/") Then
URL = URL.Trim("/")
Dim strURL As String = URL.ToLower.Split("/")(1)
Redirect301("/site.aspx?url=" & strURL)
Exit Sub
End If
The issue I'm having is for certain domain extensions, the page will just load up custom 404 Not Found and I have no idea what the cause is.
Example of pages that don't load:
/site/google.ad
/site/google.cd
I'm guessing that the system thinks that .cd and .ad files are actual physical files and when it doesn't find them, it shows the custom 404 error. It doesn't actually looks like the request is getting through to the global.asax. When working in local environment, they actually load fine but only on the live server it has this issue and this is why it has been a nightmare trying to figure it out.
Another issue I found was loading the following URL:
/site/prn.com
This shows a 404 error again but this time not the custom one I created but the actual hard looking .net 404 error page. This also works fine in local environment.
There must be some IIS setting or code change I could do to try to get this resolved.
Thank you for your time :)

Check this link . Error message when you try to browse a Web page that is hosted on IIS 7.0: "HTTP Error 404.7 – FILE_EXTENSION_DENIED
This is the reason .ad .cd extensions are blocked.
I created a new website in IIS called wbsite1. Then I added an application to website1 wich is a website called website2. The problem appeared when we tried to access links in website2. The browser always refers to the root url and redirect so we were trying to change all the urls in website2. For example, if we have a url in website2 like :
<a href='http://localhost:2030/website2/cms/default.aspx...'
and we click on that link the browser redirect us to :
http://localhost:2030/website1/default.aspx
Why am I getting this behavior? And what is the best workaround to integrate two websites without trying to mess with every link in the website? Thank you very much.
We are facing troubles when I try to access a page in the child application it redirects to the default page of the main application and gives the error:
Session state is not available in this context.
I found the solution for my question and it's this :
unfortunately i have to "rewrite" all our links in my code.
so i created a function which will automatically add prefix to external links,
and store base link for other site it configuration.
I did such project with success. thank u for all your replies
i found another solution also and it's using a web proxy but i can't use it in my scenario
As I have been requested by my instructor to use AntiXss library in the development of my senior project, I am facing a lot of difficulties of using this library because of the lack of resources on the web. A part of my project I have an upload file function where the user will be able to upload files, and after uploading his files, he will be redirected to the same page to see some other information. Everything works fine, but when I added AntiXss library and use it with the following line only, I got this error
(HTTP 400 Error - Bad Request)
and I don't know why. Could anyone tell me why I am getting this error? And how to fix it?
C# Code:
Response.Redirect(Encoder.HtmlFormUrlEncode(Request.Url.PathAndQuery));
Break up your code and look at each step:
Take the incoming request's URL, and extract out the path and query.
Run that through a form-based encoder
Redirect to that string
What do you think a form-based encoder would do in order to prevent XSS attacks?
Try this:
Response.Write(Encoder.HtmlFormUrlEncode("http://www.stackoverflow.com"));
What is written out? Try putting that in a web browser, and you'll likely get a 400 (or a 502) error.
Request.Url.PathAndQuery
The above syntax returns `/Cambia3/Temp/Test.aspx?query=arg`
For further url references check this
HtmlFormUrlEncode gets string and encode as parameters. for further info on that see here
I have a problem here. Assume there's a basic calculator implemented in javascript hosted on a website ( I have googled it and to find an example and found this one: http://www.unitsconverter.net/calculator/ ). What I want to do is make a program that opens this website, enters some value and gets the return value. So, in our website calculator, the program:
- open the website
- enters an operand
- enters an operation
- enters an operand
- retrieve the result
Note: things should be done without the need to show anything to the user ( the browser for example ).
I did some search and found about HttpWebRequest and HttpWebRespond. But I think those can be used to post data to the server, which means, The file I'm sending data to must be php, aspx or jsp. But Javascript is client side. So, I think they are kind of useless to me in this case.
Any help?
Update:
I have managed to develop the web bot using WebBrowser Control tool ( found in System.Windows.Forms )
Here's a sample of the code:
webBrowser1.Navigate("LinkOfTheSiteYouWant"); // this will load the page specified in the string. You can add webBrowser1.ScriptErrorsSuppressed = true; to disable the script in a page
webBrowser1.Document.GetElementById("ElementId").SetAttribute("HTMLattrbute", "valueToBeSet");
Those are the main methods I have used to do what I wanted to.
I have found this video useful: http://www.youtube.com/watch?v=5P2KvFN_aLY
I guess you could use something like WatiN to pipe the user's input/output from your app to the website and return the results, but as another commenter pointed out, the value of this sort of thing when you could just write your own calculator fairly escapes me.
You'll need a JavaScript interpreter (engine) to parse all the JavaScript code on the page.
https://www.google.com/search?q=c%23+javascript+engine
What you're looking for is something more akin to a web service. The page you provided doesn't seem like it accepts any data in an HTTP POST and doesn't have any meaningful information in the source that you could scrape. If for example you wanted to programmatically make searches for eBay auctions, you could figure out how to correctly post data to it eg:
http://www.ebay.com/sch/i.html?_nkw=http+for+dummies&_sacat=267&_odkw=http+for+dummies&_osacat=0
and then look through the http response for the information you're looking for. You'd probably need to create a regular expression to match the markup you're looking for like if you wanted to know how many results, you'd search the http response for this bit of markup:
<div class="alt w"><div class="cnt">Your search returned <b>0 items.</b></div></div>
As far as clientside/javascript stuff, you just plain aren't going to be able to do anything like what you're going for.
It is a matter of API: "Does the remote website expose any API for the required functionality?".
Well web resources that expose interactive API are called web service. There are tons of examples (Google Maps for istance).
You can access the API -depending on the Terms & Conditions of the service- through a client. The nature of the client depends on the kind of web service you are accessing.
A SOAP based service is based on SOAP protocol.
A REST based service is based on REST principles.
So, if there is an accessible web service called "Calculator", then you can access the service and, for istance, invoke the sum method.
In your example, the calculator is a Javascript implementation, so it is not a web service and it cannot be accessed via HTTP requests. Though, its implementation is still accessible: it is the javascript file where the calculator is implemented. You can always include the file in your website and access its functions via javascript (always mind terms and conditions!!).
A very common example is the jQuery library stored in Google Libraries.
