如何获取Laravel中URL参数的值？

Question

我在从 Fitbit 的重定向 URL 中获取 URL 参数时遇到困难我在这里尝试在不使用社交名流或任何其他软件包的情况下集成 Fitbit。

我有以下 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 我想获取 # 之后的所有信息，就像我想在这里获取 user_id

我试过这个来完成

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();
    }
}

路线

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

但是我在这里没有得到 user_id 这让我得到了完整性约束错误

如何在我的案例中得到 user_id？

Answer 1

如果您想获取用户浏览器中显示的井号或锚点后的值："standard" HTTP 无法做到这一点，因为该值永远不会发送到服务器（因此它赢了' 在 $_SERVER["REQUEST_URI"] 或类似的预定义变量中可用）。您需要在客户端使用某种 JavaScript 魔法，例如将此值包含为 POST 参数。

那部分叫做"fragment"。如果你有任何 static url 那么你可以通过这种方式获得它：

$url=parse_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");
echo $url["fragment"]; //This variable contains the fragment

您可以像 fitbitIntegration/{param} 一样定义路由，并在您的函数 fitbitIntegration 中添加参数，例如 fitbitIntegration ( Request $req, $param);然后你可以在你的参数上使用正则表达式来得到你想要的

将动态 Url 存储在控制器中的任何变量中，然后按此操作。

<?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

?>

注意： url 的片段部分在 # 之后它永远不会发送到服务器端，所以..它不可能得到那个使用 php 中的任何 $_SERVER[..] 但我们可以阅读它。所以现在我们可以使用 JAVA SCRIPT MAGIC 这样做：

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

<?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'];
}

?>
