How passing of url parameters works in facebook, twitter , youtube or other similar sites .
eg:
facebook http://www.facebook.com/stackoverflowpage
twitter: http://twitter.com/StackOverflow
you tube: http://www.youtube.com/user/BBCWorldwide
where bold ones are parameters( i believe those are parameters)
What i have seen in most websites is like this,
http://www.website.com/index.php?id=stackoverflow
then how those above websties is passing parameters in different method,how they are doing this?. Or whether when a new user is joined in those website a new file is created in their server.
eg:
http://www.facebook.com/stackoverflowpage
http://www.facebook.com/stackoverflowpage.php(or .aspx whatever methods)
This is usually done by URL rewriting on ther server side. For example using .htaccess. A typical situation is: when a request of the form http://server.com/x/y comes in, it is rewritten as http://server.com/index.php?param1=x¶m2=y and then passed on to the request processor (say, PHP).

In my Flutter (Android/iOS) app I am using Firebase Dynamic Links for Patreon.com OAuth2 apis.
My dynamic link is https://myappname.page.link/patreon
The deep link is https://myappname.net/patreon
Patreon is using the https://myappname.page.link/patreon as a redirect_url , and is supposed to append some parameters to it, so it looks like
https://myappname.net/patreon?code=xxx
However, all I receive inside my app is the naked url https://myappname.net/patreon
There are no parameters attached to it.
So how can I tell Firebase to preserve the query parameters Patreon is attaching to the redirect_url?
As an alternate question, is there a better way to listen for incoming response inside of a Flutter app, without the use of Dynamic Links?
You loose all parameters by using that.
If you're relying on Patreon to send back that parameter I'd suggest to generate a small proxy where you can redirect your calls to the dynamic link by generating it on the fly.
So:
Patreon shares www.myhost.com/supah-link?p1=aaa&p2=bbb
Your micro-service which runs on www.myhost.com/supah-link receives the call
You generate a dynamic link like the following:
https://example.page.link/?link=https://www.example.com/someresource&apn=com.example.android&amv=3&ibi=com.example.ios&isi=1234567&ius=exampleapp&p1=aaa&p2=bbb
NOTE: Pay attention to the &p1=aaa&p2=bbb parameters added
Return a 302 and redirect to your newly generated link
Based on how you configure it from the console this link can redirect to the store or your app, in your app you can listen for the link as follows:
FirebaseDynamicLinks.instance.onLink(
onSuccess: (dynamicLink) async => handleDeepLink(dynamicLink?.link),
);
In handleDeepLink you can parse your custom query parameters.
NOTE: The URL parameter you pass via the dynamic link HAS TO BE ENCODED! Which means your link will look more like this:
https://example.page.link/?link=https%3A%2F%2Fwww.example.com%2Fsomeresource%26apn%3Dcom.example.android%26amv%3D3%26ibi%3Dcom.example.ios%26isi%3D1234567%26ius%3Dexampleapp%26p1%3Daaa%26p2%3Dbbb
I am currently working on a 1 page HTML app that uses URL parameters to do an API call. the URL parameters are set and used in QR codes so its necessary that they are able to change dynamically. A example URL would be something like app.com/index.html/?environment=demo&location=Kiosk
I currently have this app deployed in AWS Amplify, but I cant get other keywords to chain together. I have the following redirects in place:
These redirects make sure that every URL parameter I pass in the link works EXCEPT some keywords like the "location" keyword, next to some others. Using this keyword as a URL param gives a 502 server error, or if the redirects are not used an access denied error.
does anyone know how to get the location keyword to work? Thanks in advance!
You should be able to use a single rule that will forward everything to index.html EXCEPT urls with a "file extension" from the list below. That lets all your links work, but assets like images, fonts, code will pass through.

We have a multi-site environment where each site has its own redirect URL. We want to use a single Client ID and Secret for our application but register multiple redirect URIs to it. Is it possible to add multiple URLs in below registration form:
I don't think there is possible solution to add on multiple URLs on the SharePoint online app registration form.
But from what i understand there is another way to achieve use a single Client ID and Secret for application and perform multiple redirects.
You can control the redirect url using the appredirect.aspx by specifying the redirect_uri parameter if you need to redirect from the default one check here for reference.
Basiclly it call the subsite page containing the below JS to install the app.
var url = String.format(
"{0}/_layouts/15/appredirect.aspx?client_id={1}&redirect_uri=https://***.azurewebsites.net/<<controller>>/<<view method containing the code to install the app>>?{{StandardTokens}}",
<<subsite url>>, "<<client id>>");
window.location.href = url;
The above javascript calls the appredirect.aspx page which then calls the app site as below,
https://****.azurewebsites.net/home?SPHostUrl=<<subsiteurl>>&SPLanguage=en-US&SPClientTag=1&SPProductNumber=**&SPAppWebUrl=<<weburl>>
Note: The above can be extended to check for the successful installation of the app and display an error message accordingly.
SPWeb.LoadAndInstallWeb equivalent REST / Javascript CSOM is also available here.

I'm trying to use facebook's oauth.
Basically facebook has to return me a "code" parameter.
But i get nothing, it just return my callback url (to the exact same url).
i'm generating this url with my app.
http://www.facebook.com/dialog/oauth?client_id=76209388873&redirect_uri=http%3A%2F%2Ffb.lous%2Fmain%2Ffacebook_callback&scope=read_stream
I used other parameters and options, just when i set response_type=token
i get parameter list for javascript (with # character instead of ?, its for client side, i'm trying to write some api bot)
So right now i can't get any parameter with someway.
I tried to solve exactly the same thing for several hours. In my case it turned out to be a stupid redirect problem. Facebook correctly redirected back to http://www.mysite.com with the code parameter, then my webapp redirected to http://www.mysite.com/users/login (because the user wasn't logged in yet). On the second redirect I lost the code parameter.
I have this facebook application which adds a custom tab to fan pages. You access the tab by an URL like:
http://www.facebook.com/pages/PAGE-NAME-HERE/PAGE-ID?v=APP-ID
I want to be able to add some extra get parameters to that URL, but it seems they don't get passed correctly because facebook is filtering them. Is there a way to pass those parameters? Even not via GET but some other kind of technique.
If you want to pass multiple querystring params though the app_data param, you can urlencode it.
All querystring params that need to propagate through a Facebook tab should be url-encoded in the app_data var.
In other words, the "&" and the "=" need to be url-encoded (especially if passing more than one param).
Examples
GOOD TAB URL (this passes all 3 params):
https://www.facebook.com/pages/yourpagename/56789?sk=app_12345&app_data=var1%3D123456789%26anothervar%3Drawr%26athird%3Dmeow
In the app_data from this signed request, I got this value: var1=123456789&anothervar=rawr&athird=meow
BAD TAB URL (this passes only the first param through the signed_request):
https://www.facebook.com/pages/yourpagename/12345?sk=app_56789&app_data=var1=123456789&anothervar=rawr&athird=meow
In the app_data from this signed request, I ONLY got this value: var1=123456789 (Facebook dropped the rest)
You can even give your media team instructions like this =)
Media team,
Here is an online utility to urlencode the querysting data you want to
embed in the app_data param: http://meyerweb.com/eric/tools/dencoder/
Base Url: https://www.facebook.com/pages/yourpagename/12345?sk=app_56789&app_data=
Steps:
Go to http://meyerweb.com/eric/tools/dencoder/
Type var1=123456789&anothervar=rawr&athird=meow in the box
Hit the Encode button
You’ll get var1%3D123456789%26anothervar%3Drawr%26athird%3Dmeow which becomes your app_data param. Append that to the baseUrl noted above like this:
https://www.facebook.com/pages/yourpagename/12345?sk=app_56789&app_data=var1%3D123456789%26anothervar%3Drawr%26athird%3Dmeow (this is the URL with the tracking params for the [banner ad] [online media] [etc])
p.s. Querystring params in non-tab pages are handled fine (https://apps.facebook.com/yourappname/Canvas.aspx?var1=123456789&anothervar=rawr&athird=meow does not strip out qs params like what happens in the Tab, for example).
You must pass the app_data parameter in the URL:
http://facebook.com/pages/:page_id/:page_name?sk=app_:app_id&app_data=my_data
You will then access it through the signed_request param. For instance with Ruby and RestGraph:
user = RestGraph.new.parse_signed_request(params[:signed_request)
data = user['app_data'] # => "my_data"
Appending app_data worked for me.
http://www.facebook.com/pages/MyPage/11111111111111?sk=app_22222222229&app_data=foo_bar
Then retrieve signed request using PHP SDK (in my case). app_data is then available in the assoc. array returned.
I was wondering the same, in my case I had needed to pass a parameter "from" to identify if user was using mobile form or web form to login. My app use Spring Security. The way I was able to do that was creating my own SocialAuthenticationFilter:
1) Add a (hidden in my case) parameter to your login form ("from" in this example).
2) Get the right SocialAuthenticationFilter.java source (in accordance with your Spring version).
3) Create your MySocialAuthenticationFilter using it.
4) In method:
getRequestedProviderId(HttpServletRequest request) is where you can
grab your parameter:
private String getRequestedProviderId(HttpServletRequest request) {
String f = request.getParameter("from");
if(f!=null) {
final String dbValue = request.getParameter("from");
request.getSession().setAttribute("from", dbValue);
}
...
And thats all. In this way after a successful authentication you will be able to recover from session your parameter.
Be aware this method is called several times during OAuth exchanging, and when it is called from the authentication provider (Facebook for example) the parameter will be null. That is the reason to check the value before save in session in order to avoid delete your right value.
I answer myself by saying this is not possible.
