Question

我正在学习import random yes = ['yes', 'Yes', 'Yeah', 'yeah', 'Yea', 'yea', 'Mhmm', 'mhmm', 'Mhm', 'mhm'] no = ['No', 'no', 'Nah', 'nah'] good = ['Good', 'good', 'Great', 'great', 'Okay', 'okay', 'Ok', 'ok', 'OK'] bad = ['Bad', 'bad', 'Not good', 'not good', 'Not well', 'not well'] random_yes = random.choice(yes) random_no = random.choice(no) random_good = random.choice(good) random_bad = random.choice(bad) greetings = ['Hola', 'Hello', 'Hi', 'Hey!','hey...'] random_greeting = random.choice(greetings) print(random_greeting) name = input('What is your name?') print('Hello', name,) question1 = ['How are you?','How are you doing?','How is your day?','How is your day going?'] random_question1 = random.choice(question1) ur1 = input(random_question1) if good in ur1: print("That's good") elif bad in ur1: print("I'm sorry") else: print("I don\'t understand")，我已经为用户登录编写了以下代码。现在我正在尝试使用以下代码显示验证错误消息：

Laravel 5

但没有显示任何内容。：（

任何想法都没有显示错误，如果用户没有输入任何值并按下提交按钮。

感谢。

Answer 1

我认为您可以修改handleLogin方法以将错误发送到视图，如下所示：

public function handleLogin(Request $request)
{
    $validator=$this->validate($request, User::$login_validation_rules);
    $data = $request->only('email', 'password');
    if(\Auth::attempt($data)) {
        return redirect()->intended('home');
    }

    return back()->withInput()->withErrors($validator->errors());
}

应该有效

您可以查看阅读Laravel文档的解决方案： https://laravel.com/docs/5.0/validation

问候！

Answer 2

为什么不使用内置寄存器功能？如果您还想要，您也可以使用Validator https://laravel.com/docs/master/validation

编写自己的注册表

$validator = \Validator::make($request->all(), User::$login_validation_rules);
if($validator->passes()) {
   // authenticate...
   // If auth failed, add message to validator
   $validator->getMessageBag()->add('password', 'Email or password invalid');   
}
return redirect()->back()->withErrors($validator)->withInput();

问题是您只处理输入错误，如果用户输入无效的电子邮件或密码，则不会显示。

laravel 5.2。*

/* app/Http/Kernel.php */

<?php

namespace App\Http;

use Illuminate\Foundation\Http\Kernel as HttpKernel;

class Kernel extends HttpKernel {

/**
 * The application's route middleware groups.

protected $middlewareGroups = [
    'web' => [

Answer 4

我正在为那些可能遇到同样问题/解决方案的人添加此功能。我是Laravel（5.2）的新手，并且一直在尝试授权和路由的不同方面。有一次，我的LaravelCollective HTML错误包开始迷路了。经过多次挫折后我发现了这个 -

我为需要授权的网页创建了一个路由组。我在该组中放置了一个表单页面。我忘记做的是从控制器中删除对该页面的授权中间件的调用 - $ this-＆gt; middleware（'auth'）;这导致请求两次调用授权。它没有强制我登录两次，但它确实导致重新创建会话并且所有以前的保存数据都丢失了。运行页面几次后，我会得到许多会话文件。
