<script>
var _hmt = _hmt || [];
(function() {
var hm = document.createElement("script");
hm.src = "https://hm.baidu.com/hm.js?080836300300be57b7f34f4b3e97d911";
var s = document.getElementsByTagName("script")[0];
s.parentNode.insertBefore(hm, s);
})();
</script>
</body>
</html>
3：提交表单路由：
Route::group(['prefix'=>'day','namespace'=>'day18'],function (){ // 处理登录 Route::post('dologin','ExamController@doLogin'); });
4：提交控制器验证
public function doLogin(Request $request){
// 去除token
$params=$request->except('_token');
// 验证非空
$this->validate($request, [
'username' => 'required',
'password' => 'required'
], [
'username.required' => '账号不可以为空',
'password.required' => '密码不可以为空'
], $params);
// 匹配数据库
$res=Admins::login($params);
// 验证账号和密码
if ($res['username']!==$params['username']){
return redirect(url('day/login'))->withErrors(['error'=>'账号错误']);
}elseif ($res['password']!==md5($params['password'])){
return redirect(url('day/login'))->withErrors(['error'=>'密码错误']);
}else{
// 记录session通过put方法
$request->session()->put('username', $res['username']);
//通过全局辅助函数
// session(['username' => $res['username']);
//验证成功跳转首页
return redirect(url('day/new'))->with('success','登录成功');
}
}
5：模型代码：
<?php namespace App\models; use Illuminate\Database\Eloquent\Model; class Admins extends Model { //链接表名 protected $table = 'admins'; //验证数据 public static function login($params) {
//验证账号 return self::where('username',$params['username']) ->first(); } }
6:效果:
