【中文标题】[Route: ] - Laravel 7 缺少必需的参数

【英文标题】：Missing required parameters for [Route: ] - Laravel 7

【发布时间】：2021-11-15 22:06:31

【问题描述】：

我在 laravel 5 的生产服务器上没有收到此错误。我进行了版本升级，但在收到此错误后。我真的不知道版本升级是否导致了这种情况。但是我在 laravel 7 中遇到了这个错误。

错误 - 缺少 [Route: ] [URI: users/user_id/privacy-groups-modal/list_id] [缺少参数：user_id, list_id] 的必需参数。 （查看：/opt/lampp/htdocs/php/resources/views/wishlist/show.blade.php）

Web.php

Route::group(['middleware' => ['imageOptimizer', 'auth']], function() 
Route::get('users/user_id/privacy-groups-modal/list_id', 'UserController@getPrivacyGroupsModel');
);

show.blade.php

这是升级后 JQuery 语法的问题吗？非常感谢您的帮助

【参考方案1】：

你必须像下面这样使用

var authID = "\Auth::id()";

var link   = " url('') /users/"+authID+"/privacy-groups-modal/list_id";

link       = link.replace("list_id", _self.attr('data-list-id'));

【参考方案2】：

你也可以使用

Route::get('users/user_id/privacy-groups-modal/list_id','UserController@getPrivacyGroupsModel')->name('user-privacy');


var link = 'route("user-privacy", [\Auth::id(), "list_id"])';
