case: of every page, flutter sends page enter event to server with actual route.
in more tab of the app, i'm showing recent pages, with the server's record. getting and pushing page works fine, but i have to get page's name by actual route as below.
if input is (full route)/customer/5ec24beb410df8000906ab5b, i'd like to find (route spec) /customer/:id. and so i can find the screen name with the route spec. is there regex way or smart way to accomplish this?
wrap-up
pre-defined routes /customer/:id, /product/:id
input /customer/5ec24beb410df8000906ab5b
output 1 -> /customer/:id (can't do)
output 2 -> with output 1, getting route's name by map (can do)

I have followed this link https://oemampedia.medium.com/how-to-do-deeplink-in-flutter-b0c9a7e1aa9d to use deep link in flutter.
My aim is to make the user click a link sent to his email address, and open this link through the flutter app, so that the user can confirm his email account. Nonetheless, the first time I click the link, it generates this error:
======== Exception caught by Flutter framework =====================================================
The following message was thrown:
Could not navigate to initial route.
The requested route name was: "/api/v1/confirm_my_account?email=a.b#domain.com&Token=blahblahblah"
There was no corresponding route in the app, and therefore the initial route specified will be ignored and "/" will be used instead.
Apparently, after debugging, the line of code generating this error is
stream.receiveBroadcastStream().listen((d) => _onRedirected(d));
Can someone give me a clue on how to proceed?
This "/api/v1/confirm_my_account?email=a.b#domain.com&Token=blahblahblah" is definitely not a name of any route in your app. You are parsing the dynamic link wrong, and it's capturing all of it and assigning it as a route name.
You need to parse the part which has something like /home_screen or the name of any route in your app where you define them in main.
I'm using FlowRouter. If I start on the homepage everything works well. I can work through the routes (change the pages) without problem. However, if I hit refresh in the browser, I get a series of errors. My url looks like this:
/story/586d536e34821281735b53a4
The ID is being returned in console under the following method:
Tracker.nonreactive(function(){
I think the subscription is being completed, so I'm a little confused as to why reloading a url is different than loading from the home page.
What am I not understanding here?
Reloading a url will make a HTTP request to server to get all the application source. Whereas navigating to a route from another one does not make any HTTP requests to get the application source because they are already available (they were loaded from the previous route), in this case the router will just get the appropriate content and render on the page. This is normal behaviour for Meteor apps and all other single-page apps
The error you encounter is because your data is not yet available on client, to fix it you could simple use a placeholder if the value is undefined.
In Drupal 7, some of (non-existing) URLs are not redirecting to 404 or any error page it should. Instead, it still remains showing its Top Parent Folder. For example like:
www.mywebsite.com/items/aaaaaaaaaaaaa
www.mywebsite.com/items/bbbbbbbbbbbbbbbbbb
Every WRONG URLs under /items/ i put like above, are showing the Page of its parent:
www.mywebsite.com/items instead of get redirected to 404
I don't want its parent to be shown if there is no page really.
But the strange thing is, it is NOT happening on every patterns. I mean, another different parents like:
www.mywebsite.com/users/aaaaaaaaaaaaa
www.mywebsite.com/users/bbbbbbbbbbbbbbbbb
For the wrong url typed-in under this /users/ parent path, it is CORRECTLY redirecting to the 404 page.
What is it please?
If I understand your question correctly, it's not a problem at all.
That's because how your/contributed/core modules hooks Drupal menu system.
If a menu item (menu router item to be specific. Think about a path like "admin/config/development/performance") has no "%" sign in it, menu callback function will be executed.
For an example, if a module registers "items" path example.com/items path would not be a 404, and the appropriate menu callback function of the menu item will be fired. That callback function can make use of further URL parts (example.com/items/123) if given.
'node' is a good example. (technically they are different menu router items though) .
Opening example.com/node will not fire a 404.
If a module registers 'items/%' , then, example.com/items will fire a 404. In other words, the second URL part is required in order to execute the menu callback function.
If the problem you are facing is related to a custom module, make sure you register the correct version of your router items. If the second URL part is required, register items/%.
You can execute a 404 by calling drupal_not_found().
Look at this, really helpfull
http://peterpetrik.com/blog/2009/11/non-existent-urls-views-2
Are you using Views for that path (/items)?
Here is an issue for Views: Prevent duplicate content (because Views returns 200 instead of 400 404)
You could create a Contextual filter to prevent this.

If you don't want this behavior, add the Global: NULL argument to Views and use the setting to validate that the argument is empty.
For Drupal 6, the module Views 404 might help.
You can configure your drupal installation to redirect to a specefic 404 page that you create..
Go to www.yoursite.com/admin/config/system/site-information and enter your 404 page .
I have two questions:
Q: 1
I'm currently developing a GWT app. The entry point for the app is: ImageViewer.java. I could well access it by http://127.0.0.1:8888/ImageViewer.html?gwt.codesvr=127.0.0.1:9997. I have a service called "Search" which has corresponding "Async" and "Impl"'s defined. Now, I call the service from client side, using RPC. I could call the service, obtain return value. Everything works fine.
However, I expect the application to show a behavioral change on URL. i.e. when a service is being accessed, I thought it would be reflected on the browser's URL something like: http://127.0.0.1:8888/search?gwt.codesvr=127.0.0.1:9997 as I've modified web.xml. However, this behavior is not realized. Any particular reason why this is not reflected??
Q:2
This one is a reverse of the previous ques. i.e. I have an application running. Let's say it has an entrypoint class(Imageviewer.java) and another composite class (searchClass.java) which would be loaded on the Imageviewer based on an event. This searchClass invokes the "search" service mentioned in the previous question.
I could load the "searchClass" in "Imageviewer", invoke the service, and the service also returns the value needed. Everything works fine... But,
I need something like this: by just typing this query string:
http://127.0.0.1:8888/search?value=John
I want the "searchClass" to be loaded on the "ImageViewer", call the service using the value(which is "john" in this case) and display the result. Is this possible at all?
what I've tried: I have tried to create a httpServletClass on the server and mapped it with the URL and could do the search. The search returns appropriate results. However, I want the results from the server to be displayed on the client. Remember, I'm directly using a servlet to read the URL and so there is no value being passed from client to server.
Thanks in advance.
A: 1. To change URL, the hash part, you need to set new history token in the History class. More about history management in this article.
A: 2. For the second part you could achieve it by changing the history token, for instance "http://127.0.0.1/search#value=John". The history service will trigger an event if the # part changes. You could also use the part with "?", as in your example, if you use Window.Location , but it will cause reload of the application, which would put the whole idea of using GWT in question.
RPC (AJAX) calls are done Via XHR and do not change the browser URL.
You can't (with the URL you presented). GWT apps normally run in one web page, i.e. the URL does not change (see how gmail changes browser url bar). What you can do is enable GWT history support. Then your url would be http://host/#search?value=queryu
project type is MVC2. Let say that i have page1. after success it write somethink to row and get new inserted row id and redirect to another page and sends row id as parameter. and user can see this parameter on querystring. and can change it. i think so taht it is problem in some situation(pages). i use for it a hidden input and after post checking parameter from query string with hidden input value. if they are not equal then writing in to log and redirectiong to error page. does my way is correct. or have a good methods.
thanks...
Exposing IDs like this is pretty standard and is what lets browser bookmarking of specific items work. Your job is to ensure that the user can only see and modify records that they should be able to.
If the user does some URL-hacking and enters the URL to an item they are not allowed to see or modify, you can either just kick them back to the parent page, or give an Access Denied message, depending upon the app/context.
The bottom line is never trust user input, including hidden form parameters.
