laravel(三)
一、composer
概念： 就是一个软件，通过该软件管理项目所需工具库，如验证码，上传文件，Excel表格导入导出等
中文官网：https://www.phpcomposer.com
常用命令
下载1：composer require 大名/小名
下载2：设置composer.json文件 + composer install
更新1：composer update 大名/小名
更新2：设置composer.json文件 + composer update
卸载1：composer remove 大名/小名
卸载2：设置composer.json文件 + composer update
使用fake类生产假数据
从composer仓库搜索工具库 输入命令进行下载
composer require fzaninotto/faker
使用:
<?php
// 引入autoload
require_once 'vendor/autoload.php';
//实例化类，通过调用属性获取假数据
// use the factory to create a Faker\Generator instance
$faker = \Faker\Factory::create();
// generate data by accessing properties
echo $faker->name . '<hr >';
echo $faker->e164PhoneNumber . '<hr >';
echo $faker->phoneNumber . '<hr >';
echo $faker->tollFreePhoneNumber . '<hr >';
// 'Lucy Cechtelar';
echo $faker->address . '<hr >';
echo $faker->imageUrl($width = 130, $height = 130) . '<hr >';
// "426 Jordy Lodge
// Cartwrightshire, SC 88120-6700"
echo $faker->text . '<hr >';
// Dolores sit sint laboriosam dolorem culpa et autem. Beatae nam sunt fugit
// et sit et mollitia sed.
// Fuga deserunt tempora facere magni omnis. Om
通过composer安装laravel
#配置通过国内镜像下载
composer config -g repo.packagist composer https://packagist.phpcomposer.com
#通过composer下载框架

数据迁移(migration)
概念:就是使用PHP管理数据库
语法\手册
http://laravelacademy.org/post/6964.html
php artisan make:migration 数据库迁移名称 （改表数据）
php artisan make:migration create_表名_table --create=表名 （创建表）
php artisan make:migration update_表名_table --table=表名 （修改表）
运行：php artisan migrate
撤销：php artisan migrate:rollback
创建表\修改表
删除database\migrations下面默认的两个数据迁移文件,
#创建表
php artisan make: migration create_a_table --create=a
#在database 目录下的migrations目录中对应的文件中添加
public function up()
{
Schema::create('a', function (Blueprint $table) {
$table->increments('id');
$table->string('name', 60);
});
}
#执行
php artisan migrate
修改表
php artisan make:migration update_a_table --table=a
#在database 目录下的migrations目录中对应的文件中添加
public function up()
{
Schema::table('a', function (Blueprint $table) {
$table->string('name', 30)->change();
$table->integer('created_at');
});
}
php artisan migrate #会报错 要安装扩展
composer require doctrine/dbal
通过数据迁移创建下属表
原生sql
create table day3_t2 (
id int primary key auto_increment comment '编号',
uname varchar(30) not null comment '用户名',
pwd char(32) not null comment '密码',
content text not null comment '内容',
created_at int not null default 0 comment '创建于',
updated_at int not null default 0 comment '更新于'
)engine=myisam charset=utf8;
数据迁移
创建数据迁移文件
php artisan make:migration create_day3_t2_table --create=day3_t2
public function up()
{
Schema::create('day3_t2', function (Blueprint $table) {
$table->engine = 'myisam';
$table->increments('id')->comment('编号');
$table->string('uname', 30)->comment('用户名');
$table->char('pwd', 32)->comment('密码');
$table->text('content')->comment('内容');
$table->integer('created_at')->default(0)->comment('创建于');
$table->integer('updated_at')->default(0)->comment('更新于');
});
}
php artisan migrate
填充数据(seeder)
数据迁移
就是用PHP管理数据库
填充数据
就是用PHP来插入测试数据
语法
创建填充器：php artisan make:seeder 填充器名称 （注：表名TableSeeder 大驼峰）
运行填充器：php artisan db:seed --class=填充器名称
php artisan make:seeder Day3T2TableSeeder
public function up()
{
Schema::create('student', function (Blueprint $table) {
$table->increments('id')->comment('编号');
$table->string('uname', 45)->comment('用户名');
$table->string('pwd', 255)->comment('密码');
$table->unsignedTinyInteger('age')->default(0)->comment('年龄');
$table->unsignedTinyInteger('sex')->default(1)->comment('性别：1-男,2-女');
$table->integer('created_at')->default(0)->comment('创建于');
$table->integer('updated_at')->default(0)->comment('更新于');
});
}
php artisan db:seed --class=Day3T2TableSeeder
faker使用
下载(注: 默认已经下载所有无需重复下载)
composer require fzaninotto/faker
可将上述代码替换如下代码即可
<?php
use Illuminate\Database\Seeder;
class Day3T2TableSeeder extends Seeder
{
/**
* Run the database seeds.
*
* @return void
*/
public function run()
{
#需求：创建10条测试数据
#步骤1：实例化faker类型
$faker = \Faker\Factory::create('zh_CN');
#步骤2：插入测试数据
for ($i=1; $i<=10; $i++) {
//通过Day3T2TableSeeder填充器插入测试数据
DB::table('day3_t2')->insert([
'uname' => $faker->name,
'pwd' => md5($faker->password),
'content' => $faker->paragraph(20),
'created_at' => time(),
'updated_at' => time()
]);
}
}
}
php artisan db:seed --class=Day3T2TableSeeder
学生管理小项目
说明:tinker是laravel自带的便于调试数据库的工具
语法: php artisan tinker
加密方式
Laravel存储用户密码非MD5算法，而是使用php5.5新函数password_hash和password_verify
加密语法：Hash::make('admin888'); 或者 bcrypt('admin888');
校验语法：Hash::check('admin888', 密文);
创建数据表
public function up()
{
Schema::create('student', function (Blueprint $table) {
$table->increments('id')->comment('编号');
$table->string('uname', 45)->comment('用户名');
$table->string('pwd', 255)->comment('密码');
$table->unsignedTinyInteger('age')->default(0)->comment('年龄');
$table->unsignedTinyInteger('sex')->default(1)->comment('性别：1-男,2-女');
$table->integer('created_at')->default(0)->comment('创建于');
$table->integer('updated_at')->default(0)->comment('更新于');
});
}
创建模型
php artisan make:model Http\Models\Student
在模型中添加
<?php
namespace App\Http\Models;
use Illuminate\Database\Eloquent\Model;
class Student extends Model
{
/**
* 设置表名
* @var string
*/
protected $table = 'student';
/**
* 声明可以批量设置的属性
* @var array
*/
protected $fillable = ['uname', 'pwd', 'age', 'sex'];
/**
* Unix时间戳填充数据（注：默认托管创建于更新于）
* @var string
*/
protected $dateFormat = 'U';
}
#指令：通过模型操作数据库
#调用工厂文件：factory(App\Http\Models\Student::class, 2)->create()
#注:工厂文件中定义的模型必须通过migration创建无法将无法找到模型
登录模块[加载视图]
步骤1：定义路由，请求/student/login交给Student\LoginController@login
步骤2：创建Student\LoginController@login并加载视图
步骤3：创建视图文件
定义路由
Route::match(['get','post'],'student/login','Student/LoginController@login')
创建控制器
<?php
namespace App\Http\Controllers\Student;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
/**
* 登录控制器
* @author zhao@itcast.cn
*/
class LoginController extends Controller
{
//登录处理方法
public function login()
{
#加载/resources/veiws/student/login/login.blade.php文件
return view('student.login.login');
}
}

步骤2：创建控制器和方法并获取数据、加载视图
步骤3：创建视图并循环显示数据
定义路由

#步骤1：数据库获取数据
$students = Student::orderBy('id', 'desc')->paginate(2);
#步骤2：加载视图并传递数据

修改连接地址附带参数
<a href="{{ url("student/upd?id=$student->id ") }}">修改</a>
创建控制器方法接受并显示视图 修改数据
public function upd(Request $request)
{
$id = $request->input('id');
$data = Student::where('id',$id)->first();

学生删除
修改连接地址附带参数id
<a href="{{ url("student/del?id=$student->id ") }}" onclick="return confirm('确定要删除吗?')">删除</a>
定义路由
Route::match(['get','post'],'/student/del', 'Student\LoginController@del');
创建控制器方法
public function del(Request $request)
{
$id = $request->input('id');
$rs = Student::where('id',$id)->delete();
if($rs){
return redirect(url('/student/index'))->with(['state'=>'success','tips'=>'添加成功']);
}else{
return redirect(url('/student/del'))->with(['state'=>'error','tips'=>'添加失败']);
}
}
