I need to redirect thousands of pages from old urls to news. I solved problem with dynamic routing, but know I need to redirect every old links.
So I try to do some httphandler – my code is here only for firs testing is here:
namespace BoardRider
{
public class RedirectHandler : IHttpHandler
{
#region IHttpHandler Members
public bool IsReusable
{
get { return true; }
}
public void ProcessRequest(HttpContext context)
{
Uri uri = context.Request.Url;
if (uri.AbsoluteUri.Contains("default2.aspx"))
{
string red = uri.AbsoluteUri;
context.Response.Redirect("~/Default.aspx");
}
}
#endregion
}
}
In web.config I have this:
<handlers>
<add type="BoardRider.RedirectHandler" path="*" name="RedirectHandler" verb="*" />
</handlers>
If I write into my handler some response.write text and in web.config I put into path for example *.exam and I write localhost://webroot/handler.exam – it works. So I think, that my http handler is registered successfully.
But if I change path to “*”, like in example above, there is some strange behavior.
If I write address localhost://webroot/default2.aspx – it redirects to default.aspx. I can see this address in address line. But I can’t see any content of page.
If I write address localhost://webroot/Events?id=2525 – I get error page “The WebResource.axd handler must be registered in the configuration to process this request.”
Please, could you help me, with this issue?
Im using Imageresizer 4 in a MVC 5 application. We have the need to authenticate the image requests so we are using the following event:
protected void Application_Start()
{
ImageResizer.Configuration.Config.Current.Pipeline.AuthorizeAllImages = true;
ImageResizer.Configuration.Config.Current.Pipeline.AuthorizeImage += AuthorizeImage;
}
The AuthorizeImage method looks like this:
private static void AuthorizeImage(IHttpModule sender, HttpContext context, IUrlAuthorizationEventArgs e)
{
//This line throws an exception if runAllManagedModulesForAllRequests is set to false
var owinContext = context.GetOwinContext();
Authorize(context, owinContext);
}
The problem is that we are using Owin so we need the OwinContext from the HttpContext. When calling the GetOwinContext method we get the following error:
No owin.Environment item was found in the context
If I set the runAllManagedModulesForAllRequests to true in web.config, everything works like it should.
But I don't want to use runAllManagedModulesForAllRequests since it has a performance impact.
My question is: Can I somehow force the Owin middleware to execute before a specific HttpModule?
Something like this(psuedo code):
<modules runAllManagedModulesForAllRequests="false">
<add name="ImageResizingModule" type="ImageResizer.InterceptModule" modulesToRunBefore="Owin........" />
</modules>
No, you'll need runAllManagedModulesForAllRequests=true, unless you can change how the owin module is registered, and tell it to run for all requests.
This error is very common, and I tried all of the solutions and non of them worked. I have disabled WebDAV publishing in control panel and added this to my web config file:
<handlers>
<remove name="WebDAV"/>
</handlers>
<modules runAllManagedModulesForAllRequests="true">
<remove name="WebDAVModule"/>
</modules>
The error still persists. This is the controller:
static readonly IProductRepository repository = new ProductRepository();
public Product Put(Product p)
{
return repository.Add(p);
}
Method implementation:
public Product Add(Product item)
{
if (item == null)
{
throw new ArgumentNullException("item");
}
item.Id = _nextId++;
products.Add(item);
return item;
}
And this is where the exception is thrown:
client.BaseAddress = new Uri("http://localhost:5106/");
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
var response = await client.PostAsJsonAsync("api/products", product);//405 exception
Any suggestions?
You are POSTing from the client:
await client.PostAsJsonAsync("api/products", product);
not PUTing.
Your Web API method accepts only PUT requests.
So:
await client.PutAsJsonAsync("api/products", product);
I had the same exception. My problem was that I had used:
using System.Web.Mvc; // Wrong namespace for HttpGet attribute !!!!!!!!!
[HttpGet]
public string Blah()
{
return "blah";
}
SHOULD BE
using System.Web.Http; // Correct namespace for HttpGet attribute !!!!!!!!!
[HttpGet]
public string Blah()
{
return "blah";
}
My problem turned out to be Attribute Routing in WebAPI. I created a custom route, and it treated it like a GET instead of WebAPI discovering it was a POST
[Route("")]
[HttpPost] //I added this attribute explicitly, and it worked
public void Post(ProductModel data)
{
...
}
I knew it had to be something silly (that consumes your entire day)
I tried many thing to get DELETE method work (I was getting 405 method not allowed web api) , and finally I added [Route("api/scan/{id}")] to my controller and was work fine.
hope this post help some one.
// DELETE api/Scan/5
[Route("api/scan/{id}")]
[ResponseType(typeof(Scan))]
public IHttpActionResult DeleteScan(int id)
{
Scan scan = db.Scans.Find(id);
if (scan == null)
{
return NotFound();
}
db.Scans.Remove(scan);
db.SaveChanges();
return Ok(scan);
}
This error can also occur when you try to connect to http while the server is on https.
It was a bit confusing because my get-requests were OK, the problem was only present with post-requests.
Chrome often times tries to do an OPTIONS call before doing a post. It does this to make sure the CORS headers are in order. It can be problematic if you are not handling the OPTIONS call in your API controller.
public void Options() { }
I'm late to this party but as nothing above was either viable or working in most cases, here is how this was finally resolved for me.
On the server the site/service was hosted on, a feature was required!
HTTP ACTIVATION!!!
Server Manager > Manage > Add Roles and Features > next next next till you get to Features > Under .NET (each version) tick HTTP Activation.
Also note there is one hidden under >net > WCF Services.
This then worked instantly!
That was melting my brain
I was getting the 405 on my GET call, and the problem turned out that I named the parameter in the GET server-side method Get(int formId), and I needed to change the route, or rename it Get(int id).
You can also get the 405 error if say your method is expecting a parameter and you are not passing it.
This does NOT work ( 405 error)
HTML View/Javascript
$.ajax({
url: '/api/News',
//.....
Web Api:
public HttpResponseMessage GetNews(int id)
Thus if the method signature is like the above then you must do:
HTML View/Javascript
$.ajax({
url: '/api/News/5',
//.....
If you have a route like
[Route("nuclearreactors/{reactorId}")]
You need to use the exact same parameter name in the method e.g.
public ReactorModel GetReactor(reactorId)
{
...
}
If you do not pass the exact same parameter you may get the error "405 method not allowed" because the route will not match the request and WebApi will hit a different controller method with different allowed HTTP method.
This does not answer your specific question, but when I had the same problem I ended up here and I figured that more people might do the same.
The problem I had was that I had indeliberately declared my Get method as static. I missed this an entire forenoon, and it caused no warnings from attributes or similar.
Incorrect:
public class EchoController : ApiController
{
public static string Get()
{
return string.Empty;
}
}
Correct:
public class EchoController : ApiController
{
public string Get()
{
return string.Empty;
}
}
Here is one solution:
<handlers accessPolicy="Read, Script">
<remove name="WebDAV" />
</handlers>
learn.microsoft.com solution article
and remove WebDAV from modules
<remove name="WebDAVModule" />
[HttpPost] is unnecessary!
[Route("")]
public void Post(ProductModel data)
{
...
}
I could NOT solve this. I had CORS enabled and working as long as the POST returned void (ASP.NET 4.0 - WEBAPI 1). When I tried to return a HttpResponseMessage, I started getting the HTTP 405 response.
Based on Llad's response above, I took a look at my own references.
I had the attribute [System.Web.Mvc.HttpPost] listed above my POST method.
I changed this to use:
[System.Web.Http.HttpPostAttribute]
[HttpOptions]
public HttpResponseMessage Post(object json)
{
...
return new HttpResponseMessage { StatusCode = HttpStatusCode.OK };
}
This fixed my woes. I hope this helps someone else.
For the sake of completeness, I had the following in my web.config:
<httpProtocol>
<customHeaders>
<clear />
<add name="Access-Control-Expose-Headers " value="WWW-Authenticate"/>
<add name="Access-Control-Allow-Origin" value="*" />
<add name="Access-Control-Allow-Methods" value="GET, POST, OPTIONS, PUT, PATCH, DELETE" />
<add name="Access-Control-Allow-Headers" value="accept, authorization, Content-Type" />
<remove name="X-Powered-By" />
</customHeaders>
</httpProtocol>
Old question but none of the answers worked for me.
This article solved my problem by adding the following lines to web.config:
<system.webServer>
<modules runAllManagedModulesForAllRequests="false">
<remove name="WebDAVModule" />
</modules>
</system.webServer>
In my case I had a physical folder in the project with the same name as the WebAPI route (ex. sandbox) and only the POST request was intercepted by the static files handler in IIS (obviously).
Getting a misleading 405 error instead of the more expected 404, was the reason it took me long to troubleshoot.
Not easy to fall-into this, but possible. Hope it helps someone.
Make sure your controller inherits from Controller class.
It might even be crazier that stuff would work locally even without that.
For my part my POST handler was of this form:
[HttpPost("{routeParam}")]
public async Task<ActionResult> PostActuality ([FromRoute] int routeParam, [FromBody] PostData data)
I figured out that I had to swap the arguments, that is to say the body data first then the route parameter, as this:
[HttpPost("{routeParam}")]
public async Task<ActionResult> PostActuality ([FromBody] PostData data, [FromRoute] int routeParam)
check in your project .csproj file and change
<IISUrl>http://localhost:PORT/</IISUrl>
to your website url like this
<IISUrl>http://example.com:applicationName/</IISUrl>
Another possible issue which causes the same behavior is the default parameters in the routing. In my case the controller was located and instantiated correctly, but the POST was blocked because of default Get action specified:
config.Routes.MapHttpRoute(
name: "GetAllRoute",
routeTemplate: "api/{controller}.{ext}"/*,
defaults: new { action = "Get" }*/ // this was causing the issue
);
I was having exactly the same problem. I looked for two hours what was wrong with no luck until I realize my POST method was private instead of public .
Funny now seeing that error message is kind of generic. Hope it helps!
We had a similar issue. We were trying to GET from:
[RoutePrefix("api/car")]
public class CarController: ApiController{
[HTTPGet]
[Route("")]
public virtual async Task<ActionResult> GetAll(){
}
}
So we would .GET("/api/car") and this would throw a 405 error.
The Fix:
The CarController.cs file was in the directory /api/car so when we were requesting this api endpoint, IIS would send back an error because it looked like we were trying to access a virtual directory that we were not allowed to.
Option 1: change / rename the directory the controller is in
Option 2: change the route prefix to something that doesn't match the virtual directory.
In my case, the 405 error only showed up in production server, and not on my dev machine.
I found that the problem was due to the fact that I simply "manually" transferred the contents of the locally published folder from my local machine to the online production server.
So, the FIX for me was to simply delete all the online files on the prod server, and then use the "Publish" option on Visual Studio to publish directly from my local machine to the prod server via FTP.
I don't know exactly why this changed something, because it seems to me the files were the same, but this thing fixed the problem and I hope it could help someone else too.
Another possible cause can be to do with Session State config in IIS causing a redirect which appends "?AspxAutoDetectCookieSupport=1" to the URL. In my case I was performing a POST but the redirect was being performed as a GET by the HttpClient.
The solution I found was to add the following to my web.config:
<system.web>
<sessionState cookieless="UseCookies" />
</system.web>
Function names make it complicated for c# sometimes. Change name of the function, it will works. Like ProductPut instead of PutProduct or Put.
public Product ProductPut(Product p)
{
return repository.Add(p);
}
Using the Microsoft.Web.Infrastructure assembly we can register modules during the pre-application start phase, as follows:
DynamicModuleUtility.RegisterModule(typeof(MyHttpModule));
Is it possible to register a custom PageHandlerFactory in ASP.NET web forms in code instead just like the example above with the module?
I currently wire this through code like this, but I find it too verbose (and it makes it much harder to create a quick start NuGet package, since I have to alter the web.config):
<?xml version="1.0"?>
<configuration>
<system.webServer>
<handlers>
<add name="CustomFactory" verb="*" path="*.aspx"
type="Shared.CustomPageHandlerFactory, Shared"/>
</handlers>
</system.webServer>
</configuration>
As far as I know, there is no way to do this in code. In my particular situation however, the solution really was to register a HTTP module.
The HTTP module can upon initialization hook onto the HttpApplication.PreRequestHandlerExecute event which is executed after the page handler factory created the Page, but before ASP.NET starts executing that page (and other handlers).
Here is an example of such a HTTP Module:
public class MyHttpModule : IHttpModule
{
void IHttpModule.Dispose() {
}
void IHttpModule.Init(HttpApplication context) {
context.PreRequestHandlerExecute +=
this.PreRequestHandlerExecute;
}
private void PreRequestHandlerExecute(object s, EventArgs e) {
IHttpHandler handler =
this.application.Context.CurrentHandler;
// CurrentHandler can be null
if (handler != null) {
// TODO: Initialization here.
}
}
}
I am hosting a wcf service in IIS 7. I was curious if it would be possible to create my own .svc HttpHandler mapping and class to handle service requests.
For example, if I was to intercept any requests to files that ended with an extension of ".foo" I could add this to my web.config
<handlers>
<add name="*.foo_**" path="*.foo" verb="*" type="MyServer.FooHttpHandler" />
</handlers>
And I could have a class in my default root that did the following
public class FooHandler: IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
// do stuff, validate?
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.ClearHeaders();
HttpContext.Current.Response.AddHeader("Content-Disposition", string.Format("filename={0}", url));
HttpContext.Current.Response.AddHeader("Content-Type", "fooMimeType");
HttpContext.Current.Response.WriteFile(url);
HttpContext.Current.Response.End();
}
public bool IsReusable
{
get { return false; }
}
}
Is it possible to do something like this with wcf .svc requests? I'm not sure if it'd be the exact same thing or not, since I'm not necessary serving a file to respond with, I want to intercept and proxy the response.
Or is a better way to implement a service behavior that does my required pre-service logic?
What are you trying to achieve? Not sure if you can replace the existing *.svc http handler - but what you can do much more easily is create your own custom ServiceHostFactory for the WCF service. You basically add one attribute your *.svc file:
<%# ServiceHost Language="C#" Debug="true"
Service="YourNamespace.YourService"
Factory="YourNamespace2.YourServiceHostFactory" %>
Using this, IIS will now instantiate your own YourServiceHostFactory and ask you to create an instance of the YourService class. Maybe you can hook into the flow here and do what you need to do?
You could use ASP.NET Routing and an IRouteHandler that returns your own IHttpHandler implementation as well if you really want to as well

http://msdn.microsoft.com/en-us/library/cc668201.aspx
I've done this in the past when setting up WCF Data Services and I don't see why it can't work here as well.
