我正在创建一个带有 lumen truing 的 API 以使用 JWT 身份验证，我执行了 JWT 文档中的所有步骤，如下所示，但当我测试它时，出现错误：

用户模型

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Tymon\JWTAuth\Contracts\JWTSubject;

class User extends Model implements JWTSubject 
{
    protected $fillable = [
        'username',
        'password',
        'email',
        'fullname',
        'natId',
        'role',
    ];

    public function Predector()
    {
        return $this->hasMany('App\Models\Predect');
    }

    /**
     * Get the identifier that will be stored in the subject claim of the JWT.
     *
     * @return mixed
     */
    public function getJWTIdentifier()
    {
        return $this->getKey();
    }

    /**
     * Return a key value array, containing any custom …

我Row在 Flutter 应用程序中有这个小部件，带有一些IconButtons

Row(
  mainAxisAlignment: MainAxisAlignment.spaceBetween,
  children: [
    IconButton(
      icon: Icon(Icons.skip_previous,
        color: Colors.amber, size: 35),
      onPressed: () {
        setState(() {
          pageIndex = 1;
        });
      }),
    IconButton(
      icon: Icon(Icons.arrow_left,
        color: Colors.amber, size: 45),
      onPressed: decIndex),
    Text('Page $pageIndex',
      textAlign: TextAlign.center,
      style: TextStyle(
        color: Colors.amber,
        fontSize: 20,
        fontWeight: FontWeight.bold)),
    IconButton(
      icon: Icon(Icons.arrow_right,
        color: Colors.amber, size: 45),
      onPressed: () {
        incIndex(pageNumbers);
      }),
    IconButton(
      icon: Icon(Icons.skip_next,
        color: Colors.amber, size: 35),
      onPressed: () {
        setState(() {

我在本地主机服务器上有 laravel 应用程序，我想通过 wamp 服务器将其共享到本地网络，我查看了此处的帖子并执行了大部分操作，例如：

将 httpd-vhosts.conf 更改为：

<VirtualHost *:80>
    ServerName localhost
    DocumentRoot D:/wamp/www
    <Directory  "D:/wamp/www/">
        Options +Indexes +FollowSymLinks +MultiViews
        AllowOverride All
        Require all granted
    Order Deny,Allow
    Allow from all
    </Directory>
</VirtualHost>

在防火墙系统中为 TCP 创建新规则。将 C:\Windows\System32\drivers\etc\host 更改为：

#127.0.0.1 localhost
192.168.0.105 attendance

将监听 192.168.0.105:80 添加到 httpd.conf

并且没有解决

我有一个应用程序尝试使用提供程序将产品添加到卡中，首先我有这个产品型号：

class Products {
  final String item;
  final int price;    
  Products({this.item, this.price});
}

然后我有这个小部件来查看产品列表，它显示成功：

import './service/provider.dart';
import 'package:flutter/material.dart';
import 'package:provider/provider.dart';    
import 'models/products.dart';    
class ProductList extends StatelessWidget {
  @override
  List<Products> myProducList;
  Widget build(BuildContext context) {
    myProducList = [
      Products(item: 'Car', price: 20000),
      Products(item: 'PC', price: 500),
      Products(item: 'LapTop', price: 750),
      Products(item: 'House', price: 25000),
    ];
    return Scaffold(
      body: ListView.builder(
          shrinkWrap: true,
          itemCount: myProducList.length,
          itemBuilder: (context, index) {
            return Card(
              child: ListTile(
                title: Text(myProducList[index].item),
                subtitle: Text(myProducList[index].price.toString()),
                trailing: IconButton(
                  icon: Icon(Icons.add),
                  onPressed: () …
