How to get values of URL parameters in Laravel?

Question

I'm facing difficulty in fetching URL parameters from redirect URL of Fitbit I'm here trying to integrate Fitbit without using socialite or any other package.

I have the following URL:

http://localhost/abc/public/portal/fitbit/fitbitIntegration#access_token=eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiI1WjVLUzUiLCJhdWQiOiIyMjhMNjUiLCJpc3MiOiJGaXRiaXQiLCJ0eXAiOiJhY2Nlc3NfdG9rZW4iLCJzY29wZXMiOiJ3aHIgd251dCB3cHJvIHdzbGUgd3dlaSB3c29jIHdzZXQgd2FjdCB3bG9jIiwiZXhwIjoxNTA1NDU5MTM2LCJpYXQiOjE1MDQ4NzE1MjF9.iQ9nxbzmvar2DlG_848b3MTefq7q0wxyXByTb1Bb2o4&user_id=5Z5KS5&scope=sleep+settings+nutrition+activity+social+heartrate+profile+weight+location&token_type=Bearer&expires_in=587615

All I want to fetch all the information after the # like I want to get user_id here

I have tried this to accomplish

public function fitbitIntegration(Request $request)
{
    try{
        $authId = Auth::user()->id;

        $fitbit = new FitbitMaster();
        $fitbit->user_id = $authId;
        $fitbit->fitbit_client_id = $request->user_id;
        $fitbit->save();
        flash('Connected', 'success');
        return redirect()->back();
    }
    catch (QueryException $exception)
    {
        echo $exception->getMessage();
    }
}

Route

Route::get('fitbitIntegration', 'BackEnd\fitbit@fitbitIntegration');

But I'm not getting the user_id here which got me Integrity constraint error

How to get user_id here in my case?

Store Your Dynamic Url in any variable, in your controller and Do Like This.

<?php

//store  your dynamic url in any variable

    $url = "http://localhost/abc/public/portal/fitbit/fitbitIntegration#access_token=eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiI1WjVLUzUiLCJhdWQiOiIyMjhMNjUiLCJpc3MiOiJGaXRiaXQiLCJ0eXAiOiJhY2Nlc3NfdG9rZW4iLCJzY29wZXMiOiJ3aHIgd251dCB3cHJvIHdzbGUgd3dlaSB3c29jIHdzZXQgd2FjdCB3bG9jIiwiZXhwIjoxNTA1NDU5MTM2LCJpYXQiOjE1MDQ4NzE1MjF9.iQ9nxbzmvar2DlG_848b3MTefq7q0wxyXByTb1Bb2o4&user_id=5Z5KS5&scope=sleep+settings+nutrition+activity+social+heartrate+profile+weight+location&token_type=Bearer&expires_in=587615";


    $access_token = substr($url, strpos($url, "#") + 1);    

    echo $access_token; // get the string of acess token with parametes

?>

UPDATED

NOTE: fragment part of url after the # It's never sent to the server side, So.. its not possible to get the that using any $_SERVER[..] in php but we can read it. So Now we can use JAVA SCRIPT MAGIC do this:

-------------------------------------------------------------------------------

<?php 

//Here you Can See save.php page inside an $url where its redirect with your access_token after clicking on `Click Here` link (in your case its redirect routes `fitbitIntegration` as you mentioned ). So i try to create the situation as your routes after its redirect with token, Fine !! 

$url = "http://localhost/save.php/fitbitIntegration#access_token=eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiI1WjVLUzUiLCJhdWQiOiIyMjhMNjUiLCJpc3MiOiJGaXRiaXQiLCJ0eXAiOiJhY2Nlc3NfdG9rZW4iLCJzY29wZXMiOiJ3aHIgd251dCB3cHJvIHdzbGUgd3dlaSB3c29jIHdzZXQgd2FjdCB3bG9jIiwiZXhwIjoxNTA1NDU5MTM2LCJpYXQiOjE1MDQ4NzE1MjF9.iQ9nxbzmvar2DlG_848b3MTefq7q0wxyXByTb1Bb2o4&user_id=5Z5KS5&scope=sleep+settings+nutrition+activity+social+heartrate+profile+weight+location&token_type=Bearer&expires_in=587615";

?>

<a  target="_blank" href="<?php echo $url; ?>"> Click Here </a>

<?php
echo '<br><br><br>';
?>


<!-- Now after redirect you have to use an javascript inside controller or inside an routes directly to aceess the url an getting an access_token, here i try to store inside the cookies of using js and retrieve it using php and echo -->

<?php

echo "<script language='javascript'>

token = window.location.hash.split('#')

    document.cookie='access_token='+token[1];
    document.cookie='token[1]';
    alert(token[1]);
    document.cookie='token[1]';

    if (token[1] != '') {
        //window.location.reload()
        //location.reload(true);
}
else{

//document.cookie='token[1]'; 

}

</script>";

//token_name=$_COOKIE['access_token'];

// Here We get the  access token inside the $_COOKIE['access_token'];  

if(isset($_COOKIE['access_token'])){

    echo $_COOKIE['access_token'];
}

?>

Output:
