Laravel 5框架学习之模型、控制器、视图基础流程_PHP
添加路由
代码如下:
Route::get('artiles', 'ArticlesController@index');
创建控制器
代码如下:
php artisan make:controller ArticlesController --plain
修改控制器
<?php namespace App\Http\Controllers; use App\Article; use App\Http\Requests; use App\Http\Controllers\Controller; use Illuminate\Http\Request; class ArticlesController extends Controller { public function index() { $articles = Article::all(); return $articles; } }
可以在浏览器中看到返回的 JSON 结果,cool!
修改控制器,返回视图
public function index() { $articles = Article::all(); return view('articles.index', compact('articles')); }
创建视图
@extends('layout') @section('content') <h1 id="Articles">Articles</h1> @foreach($articles as $article) <article> <h2 id="article-title">{{$article->title}}</h2> <div class="body">{{$article->body}}</div> </article> @endforeach @stop
浏览结果,COOL!!!!
显示单个文章
添加显示详细信息的路由
代码如下:
Route::get('articles/{id}', 'ArticlesController@show');
其中,{id} 是参数,表示要显示的文章的 id,修改控制器:
public function show($id) { $article = Article::find($id); //若果找不到文章 if (is_null($article)) { //生产环境 APP_DEBUG=false abort(404); } return view('articles.show', compact('article')); }
laravel 提供了更加方便的功能,修改控制器:
public function show($id) { $article = Article::findOrFail($id); return view('articles.show', compact('article')); }
It's cool.
新建视图
@extends('layout') @section('content') <h1 id="article-title">{{$article->title}}</h1> <article> {{$article->body}} </article> @stop
在浏览器中尝试访问:/articles/1 /articles/2
修改index视图
@extends('layout') @section('content') <h1 id="Articles">Articles</h1> <hr/> @foreach($articles as $article) <article> <h2> {{--这种方式可以--}} <a href="/articles/{{$article->id}}">{{$article->title}}</a> {{--这种方式更加灵活,不限制路径--}}<br> <a href="{{action('ArticlesController@show', [$article->id])}}">{{$article->title}}</a> {{--还可以使用--}}<br> <a href="{{url('/articles', $article->id)}}">{{$article->title}}</a> </h2> <div class="body">{{$article->body}}</div> </article> @endforeach @stop
以上所述就是本文的全部内容了,希望能够对大家学习Laravel5框架有所帮助。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.
