带参数的Laravel路由导致404

问题描述：

I have a route setup which is throwing a 404 in my Laravel 5.6 app.

The problematic route is:

Route::get('/project/{project_id}/issue/create', 'IssueController@create');

If I remove the {project_id} parameter the view loads..but I need to be able to pass this id since I will be using it on this view to create new issues that are assigned to a project. All of the other routes work without issue.

My routes file (web.php) looks like this:

Route::get('/projects', 'ProjectController@index');
Route::get('/project/{project_id}', 'ProjectController@show');
Route::get('/project/{project_id}/issue/{issue_id}', 'IssueController@show');
Route::get('/project/{project_id}/issue/create', 'IssueController@create');

And my create function in the IssueController file is this:

public function create()
{
    return view('issue.create');
}

我的路由设置在我的Laravel 5.6应用程序中抛出了404. p>

有问题的路线是： p>

Route :: get（'/ project / {project_id} / issue / create'，'IssueController @ create'）; code > p>

如果我删除 {project_id} code>参数，视图会加载..但我需要能够传递此ID，因为我将在此处使用它查看以创建分配给项目的新问题。所有其他路由都没有问题。 p>

我的路由文件（web.php）如下所示： p>


  Route :: get  （'/ projects'，'ProjectController @ index'）; 
Route :: get（'/ project / {project_id}'，'ProjectController @ show'）; 
Route :: get（'/ project / {project_id} / issue  / {issue_id}'，'IssueController @ show'）; 
Route :: get（'/ project / {project_id} / issue / create'，'IssueController @ create'）; 
  code>  pre> \  n 
 我在IssueController文件中的create函数是这样的： p> 
 
 
  public function create（）
 {
 
 
 
 
 
返回视图（'issue.create'）  ; 
} 
  code>  pre> 
  div>

答

You missed project_id as parameter of your create method. Try this:

public function create($project_id)
{
    return view('issue.create');
}

and make a route like this:

Route::get('/project/issue/create/{project_id}','IssueController@create');
