ViewController.php

<?php
namespace App\Http\Controllers\AddressBook;
use DB;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Input;
use Illuminate\Support\Facades\Session;
use Illuminate\Support\Facades\Validator;
use Illuminate\Support\Facades\Redirect;

class ViewController extends Controller
{
    /**
     * Show a list of all of the application's users.
     *
     * 
     */
      Public function getContacts(){

        $contacts= AddressBookModel::all();

        $data = ['contacts' => $contacts];
        
        return view('view')->with($data);

        }
        
}

<!DOCTYPE html>
<html>
    <head>
        <title>Test</title>
    </head>
    <body>
        <h2 align="center">These are the Registered Contacts in the Database</h2>
    </body>
</html>

路由工作正常，其连接和显示的内容都在view.blade.php中

    @foreach($contacts as $display) {{$display}}
    @endforeach

view.blade.php

<?php
namespace App\Http\Controllers\AddressBook;
use DB;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Input;
use Illuminate\Support\Facades\Session;
use Illuminate\Support\Facades\Validator;
use Illuminate\Support\Facades\Redirect;

class ViewController extends Controller
{
    /**
     * Show a list of all of the application's users.
     *
     * 
     */
      Public function getContacts(){

        $contacts= AddressBookModel::all();

        $data = ['contacts' => $contacts];
        
        return view('view')->with($data);

        }
        
}

<!DOCTYPE html>
<html>
    <head>
        <title>Test</title>
    </head>
    <body>
        <h2 align="center">These are the Registered Contacts in the Database</h2>

试验
这些是数据库中已注册的联系人

试试这个：控制器：

    public function getContacts()
    {
         // Try to name your model Contact instead of AddressBookModel
         $contacts= AddressBookModel::all();// = Contact::all();       
         return view('view')->withContacts($contacts);
    }

视图：


试验
这些是数据库中已注册的联系人
名称
电话
@foreach（$contacts$as$contact）
{{$contact->name}
{{$contact->phone}
@endforeach

我在view.blade.php中添加了这个函数

    @foreach($contacts as $display) {{$display}}
    @endforeach

谢谢你的意见。它帮助我很好地实现了这一目标，尽管这很有效
