I've written a small demo application using the ASP.net SignalR library. It works fine when run locally, but when I deploy it to my server hosted by GoDaddy, it gives the following error: GET http://xxxxxxx.com/techdemo/signalr/hubs 404 (Not Found)
I did a Google search and was only able to find this one article: https://blog.adamzolo.com/hosting-signalr-godaddy-full-trust/. Unfortunately, the advice there didn't fix my problem.
I know from the documentation that signalr/hubs is a Javascript file generated by SignalR. Somehow, it doesn't get loaded when the site is hosted by GoDaddy. I need to get this working, so what do I do to make it work?
I've developed a new WEB API 2 that works great locally, however when I upload the same code to my production server (Arvixe in this case) all I get is a 404 when I call it. I've spent HOURS searching the web, reading forums, etc.. and have been able to find no resolution, so I'm asking here as my last effort.
I'm currently only testing with the default project that gets created when you do New Project > ASP.NET Web API 2 Empty Project in Visual Studio. This creates an empty project with a single ValuesController. You should be able the JSON response by called /api/values, but this doesn't even work.
I'm using Fiddler to test the API locally and on the web server.
http://localhost:1993/api/values <--- works great
but
http://api.mydomain.com/api/values <--- returns 404
Note: I created a subdomain "api" in this case, but everything for the code for the API is unchanged from when it was created.
Why in the world does this work locally but not on the production web server?
That the server returns 404 (Not Found) may indicate a lot of things. However you can check using the following step:
Add a simple text document like readme.txt to your a folder sub-domain http://api.mydomain.com, and try to get access to that. If you can't access to that file, it means that the subdomain is not configured properly.
Publish the webservice using the "Publish" functionality, so that all DLLs will be copied.
After that,try to reach the Web ApI again.
Hope that help.
"Note: I created a subdomain 'api' in this case, but everything for the code for the API is unchanged from when it was created."
Above comment of your's is suspicious, you should publish your WEB API application in the root directory. Like if http://example.com is pointing to "MyExample" folder, then application should be published on "MyExample" folder.
After that you will be able access your api with http://example.com/api/{controller}/{action}
Just a simple suggestion which I'm sure you have already considered, but have you opened the http port 80 on the server's firewall?
Also stick a plain old html file in the root of your project and see if the server serves it up.
in your case, since you create a subdomain of 'api', you should try
http://api.mydomain.com/api/api/values
note that if you're using database for the function, you should change the connectionString in your web config
Please verify the .net framework on you hosted domain that may be old one.
Web api 2 is supposed on 4.5 framework.
One reason for web api 2 method working OK on local machine but not on production server is that the method you are calling is working on local machine but not on remote server. In such a case you will receive message 404 or 500, and you would be lost why this routing is failing.
Why a method would fail on remote server, well there may be many reasons. For me, I was querying database in my method and my connectionString was not set for remote server.
One way of resolving it would be to put some very simple code in that particular method and test that routing is working. Then check your original code for errors reasons.
I have a RESTful service on a server whose url say is www.webserve.com
i have a proxy client on my local machine to hit and get the details from this service.. the client has a page name default.aspx which post and hit the www.webserve.com and get the data.
it works fine but as soon as i upload this client on the same server(IIS) with a name say www.proxyclient.com and open it with my browser the default.aspx works fine but as soon as i post the data and hit the service through it it gives mt a 404 error..
I dont know whats wrong with it.. may be this is the static vs dynamic IP mess or something like that..
can u please help me out. i need to get this done on urgent basis
Thnx guys
Alright got the solution. my proxyclient was using a handler to handle a custom extension. I mapped that extension to IIS with aspnet dll and it worked.. thnx guys for ur support :)
Actually I needed to register .svc to my IIS ISAPI with .net framework dll
then it worked fine :)
Hi
I made a simple application in Silverlight to facebbok with the facebook C# SDK, and it runs fine in a localhost. I have published on a server and know start the problems. When I try to run the application from the facebook I get the this messege (405 - HTTP verb used to access this page is not allowed.)
anyone have any ideias of what is the problem ??
thanks
That sounds like server/IIS/Web server configuration. Try hosting the web site in an iframe locally and see if you can get there...
I have code running in an ascx within PageLayout within SharePoint 2007 that accesses files on a remote server i.e. File.Create("\servername\sharename\folder\file.txt"). The code runs within a SharePoint web application that has CAS trust set to Full in the web.config. The File.Create throws the following exception:-
System.UnauthorizedAccessException
Access to the path '\\servername\sharename\folder\file.txt' is denied.
The share is shared to Everyone with Full Control and the NTFS permissions are set to Everyone with Full Control. The web application app pool is running under a domain account also with explicit permissions to access that resource (not that this should be needed).
I ran Process Monitor on the remote machine and no hits were being recorded on the server. This leads me to believe that it is an issue with the SharePoint Code Access Security settings. Like I've said above, the trust in the web.config is set to Full.
Is it possible that CAS is still blocking the remote access? Can anyone think of any other area to review?
Update
A bit more information...
I've tried making the app pool acct domain admin and the problem still occurs. When using the same method to access a drive on the local machine it works fine. Running the same code in SnippetCompiler outside of sharepoint using the app pool account works fine.
Hope this helps, let me know if you can think of any more avenues of investigation or tests I can try.
Update
Im not sure if this would affect the issue but the local server is running Windows Server 2003 and the remote server is running Windows 2000.
Update
I've just tried running the code through a web part and it works fine. The file structure I use in the project that is failing is as follows:-
wss
- VirtualDirectories
- SharePointWebApp
- ...sp web app files
- .
- .
- PageLayoutControls
- control.ascx
- .
- .
Then in IIS I have the following structure:-
IIS
- Websites
- SharePointWebApp (pointing to \wss\VirtualDirectories\SharePointWebApp)
- PageLayoutControls (virtual directory pointing to \wss\VirtualDirectories\PageLayoutControls)
Then within the PageLayouts I reference the controls using the following:-
<%# Register TagPrefix="TEST" TagName="MyControl" Src="~/PageLayoutControls/control.ascx" %>
<asp:Content ContentPlaceholderID="PlaceHolderMain" runat="server">
<TEST:MyControl id="myControl" runat="server"/>
</asp:Content>Let me know if you need more info.
Update
The mystery deepens...
When I access the sharepoint site from Internet Explorer (6 or 7) on the SharePoint web front end server I do NOT get the exception.
When I access the sharepoint site from Mozilla Firefox from the SP web front end server I DO get the exception.
When I access the sharepoint site remotely from ANY browser I get the exception.
Also, it makes no difference what user I use to log on to the site, as long as they have permissions to access the sharepoint site.
Any thoughts?
Update
Hmm, I've now found that if I access the sharepoint site remotely and the sharepoint site tries to do a File.Create() locally (i.e. File.Create("C:\temp\abc.txt")) then it works. If I access the sharepoint site from the sharepoint box and do a File.Create() remotely (i.e. File.Create("\ServerName\ShareName\FolderName\file.txt")) then it works.
It only fails when I access the sharepoint site remotely and have the sharepoint site try to do a File.Create() remotely as well. Kind of a double hop problem. This makes me think it may be an NTLM / Kerberos issue.
Currently, we are running using NTLM authentication.
Has anyone else experienced this sort of issue?
Update
Yep, I'm pretty sure this is an NTLM issue not allowing a double hop. I just changed the authentication on the sharepoint site to use Basic Authentication and its worked. Changed it back to Integrated Authentication and it failed.
Now to decide whether to move the farm to use Kerberos or find another way around the issue. :-/
Update
Just giving SPSecurity.RunWithElevatedPrivileges a shot now. One thing though, is RunWithElevatedPrivileges meant to be used in this context? Previously, I've only used it to get access to lists and libraries within SharePoint rather than accessing a file access the network.
Any thoughts?
Update
Yep, SPSecurity.RunWithElevatedPrivileges resolves the issue. :-)
I wonder if this is the double-hop issue and that your code is trying to access the resource as the impersonated user, but that fails because NTLM will not impersonate to another server (Kerberos would).
Have you tried SPSecurity.RunWithElevatedPrivileges? That would remove the impersonation (RevertToSelf) and then maybe the application pool owner can just act as himself (herself?) whereas maybe it couldn't before.
Just a thought and should be pretty easy to try out.
