I have installed the Blog module for SilverStripe 4, but do not want all the different routes that it has available.
I want to remove for instance the "profile", "archive" and "tag" routes. Those routes are defined by the module's BlogController class.
How can I ensure these are replaced with a HTTP 404 response?
Within your_module_folder/_config/config.yml_if you indicate it should be processed After the blog module and you define those routes it should overwrite them:
---
name: your_module
After:
- 'blog/*'
---
SilverStripe\Control\Director:
rules:
'profile/': 'MyCustomController'
'archive/': 'MyCustomController'
'tag/': 'MyCustomController'
Please review the routing documentation
The controller should only have one action that throws a 404 http error.
use SilverStripe\Control\Director;
use SilverStripe\View\Requirements;
class MyCustomController extends Controller {
private static $allowed_actions = ['index'];
public function index(HTTPRequest $request) {
return $this->httpError(404, "Not Found");
}
}

I have created react application with vertex following https://how-to.vertx.io/single-page-react-vertx-howto/. I have set react routing using react-router which works fine when i use the internal react node server which runs on localhost:3000 by default.But when i trid to serve static pages via vertx static handler except for default / route other routes return "Not Found"
enter image description here
When the static website is built, it consists in a single index HTML file.
The React Router allows to create paths for specific views. These paths can be interpreted by the React Router but they do not map to actual files on the backend server.
This is why you get a 404 NOT FOUND response if you try to load anything else than /.
To fix the issue, configure the Vert.x Web Router to reroute anything the StaticHandler could not load to /:
// After you've setup the other routes
router.get().handler(StaticHandler.create());
router.get().handler(rc -> rerouteToIndex(rc));
private void rerouteToIndex(RoutingContext rc) {
if (!"/".equals(rc.normalisedPath())) {
rc.reroute("/");
} else {
rc.next();
}
}
I have a Gatsby site and due to some specific requirements, I need to redirect anyone who attempts to hit a specific URL path, for which there is no page, to an external site. This URL path is not a page within the site, but it's something that a user may be inclined to type due to documentation that is out of my control.
Here's an example: Let's say the site is located at https://www.example.com. A user may visit https://www.example.com/puppies, which does not exist. My file structure does not contain a src/pages/puppies.js file. However, when that URL is entered, I need to redirect the user to another site altogether, such as https://www.stackoverflow.com.
I haven't used Gatsby to that extent to know it has a configuration for this, so someone else may correct me. The way I would handle this is through the hosting provider where your app is.
For example, if you are using Netlify:
Create a _redirects file with the following content:
/* /index.html 200
Or
[[redirects]]
from = "/*"
to = "/index.html"
status = 200
This will cause all https://yourwebsite.com/IDontHaveThisRoute to fallback to /index.html where your .js is loaded.
I provided the Netlify example only to give you the basic idea of how it can be done through the hosting provider of your choice. I would look into configurations I can put into redirects where my domain is deployed.
Thanks to Paul Scanlon he mentioned using onRouteUpdate in Gatsby and it works like a charm
import { navigate } from 'gatsby';
export const onRouteUpdate = ({ location }) => {
if (location.pathname === '/dashboard') {
navigate('/dashboard/reports');
}
};
This question helped point me in the right direction. I was able to get it to work using Gatsby's componentDidMount() to force a redirect as shown below, using a new file called puppies.js to "catch" the path typed by the user:
// puppies.js
import React, { Component } from 'react'
class Puppies extends Component {
componentDidMount() {
window.location.replace("https://www.stackoverflow.com");
}
render() {
return <div />
}
}
export default Puppies
hey everyone i have an issue with thymeleaf and my static html pages
to be more specific i have a spring mvc web application am using also spring security , well in my login page i want to use thymeleaf so can spring security communicate with client layer in the other side i don't want to include thymeleaf in my all html pages cause am going to use AngularJs
I tried to put the login in templates folder and the other's in the static folder but id doesn't work
this is my thymleaf configuration class
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.thymeleaf.spring3.SpringTemplateEngine;
import org.thymeleaf.spring3.view.ThymeleafViewResolver;
import org.thymeleaf.templateresolver.ServletContextTemplateResolver;
#Configuration
public class ThymeleafConfig {
#Bean
public ServletContextTemplateResolver templateResolver() {
ServletContextTemplateResolver resolver = new ServletContextTemplateResolver();
resolver.setPrefix("/WEB-INF/vues/");
resolver.setSuffix(".html");
resolver.setTemplateMode("HTML5");
resolver.setOrder(1);
return resolver;
}
#Bean
public SpringTemplateEngine templateEngine() {
SpringTemplateEngine engine = new SpringTemplateEngine();
engine.setTemplateResolver(templateResolver());
return engine;
}
#Bean
public ThymeleafViewResolver thymeleafViewResolver() {
ThymeleafViewResolver resolver = new ThymeleafViewResolver();
resolver.setTemplateEngine(templateEngine());
return resolver;
}
}
my problem is i don't want Thymeleaf included in my all pages you know XHTML is pretty annoying with closing the html tag
any guide will be thankfull
Well i think you dont have to use the XHTML Syntax if u are not including thymleaf into the specific page.
I'm working on an angular app using play framework for my rest-services. Everything in the public folder is an angular app (stylesheets, javascripts, images and html). I want every request that is not for something in the stylesheets, javascripts, templates or images folder to be routed to the index.html page. This is so that angular routing can take over from there...
As a side note i can mention that I am going to place every restservice under /services/ which links to my own java controllers.
Is it possible in play framework 2.3.4 to define a route that catches all without having to use the matching elements?
This is my route defs so far:
GET / controllers.Assets.at(path="/public", file="index.html")
GET /stylesheets/*file controllers.Assets.at(path="/public/stylesheets", file)
GET /javascripts/*file controllers.Assets.at(path="/public/javascripts", file)
GET /templates/*file controllers.Assets.at(path="/public/templates", file)
GET /images/*file controllers.Assets.at(path="/public/images", file)
#this line fails
GET /* controllers.Assets.at(path="/public", file="index.html")
It's not possible to omit usage of matching elements but you can route a client via controller. The route definition looks like this:
GET /*path controllers.Application.matchAll(path)
And the corresponding controller can be implemented as follows:
public class Application extends Controller {
public static Result matchAll(String path) {
return redirect(controllers.routes.Assets.at("index.html"));
}
}
Update
If you don't want to redirect a client you can return a static resource as a stream. In this case a response MIME type is required.
public class Application extends Controller {
public static Result matchAll(String path) {
return ok(Application.class.getResourceAsStream("/public/index.html")).as("text/html");
}
}
For this task you can use onHandlerNotFound in Global class which will render some page without redirect:
import play.*;
import play.mvc.*;
import play.mvc.Http.*;
import play.libs.F.*;
import static play.mvc.Results.*;
public class Global extends GlobalSettings {
public Promise<Result> onHandlerNotFound(RequestHeader request) {
return Promise.<Result>pure(notFound(
views.html.notFoundPage.render(request.uri())
));
}
}
Answer for scala developers using playframework :)
Similar to above one about creating controller which will accept parameters and then omit them.
Example routing:
GET / controllers.Assets.at(path="/public", file="index.html")
GET /*ignoredPath ui.controller.AssetsWithIgnoredWildcard.at(path="/public", file="index.html", ignoredPath: String)
controller with assets injected by framework:
class AssetsWithIgnoredWildcard #Inject() (assets: Assets) {
def at(
path: String,
file: String,
wildcardValueToIgnore: String,
aggressiveCaching: Boolean = false): Action[AnyContent] = {
assets.at(path, file, aggressiveCaching)
}
}
Steps I took to setup project:
created new asp.net project
Install-Package Nancy.Viewengines.Razor
added Views/hello.cshtml (simple hello world html)
added MainModule.cs
hit ctrl-F5 (it returns the directory listing)
change url to localhost:41915/hello
Then I get 404 resource not found.
What am I missing?
// MainModule.cs
namespace MyProj
{
using Nancy.Routing;
using Nancy;
public class MainModule : NancyModule
{
public MainModule(IRouteCacheProvider routeCacheProvider)
{
Get["/hello"] = parameters => {
return View["hello.cshtml"];
};
}
}
}
You need the Nancy.Hosting.AspNet package too.
