php - symfony mime 错误尝试在 laravel 7 中以 crud 形式上传图像

Question

我正在做一个 laravel7 项目

我想做一个简单的crud，没有身份验证，具有一对多的关系，并且表单的元素之一是图像。

问题是我尝试使用各种解决方案，我在网上搜索 laravel image crud 示例，但是当我尝试使用图像作为输入创建产品时，我一直遇到这个错误：

Symfony Exception

LogicException

Unable to guess the MIME type as no guessers are available (have you enabled the php_fileinfo extension?).

  if (!$this->isGuesserSupported()) {            
     throw new LogicException('Unable to guess the MIME type as no guessers are available (have you 
    enabled the php_fileinfo extension?).');        
}

• 我公开制作了文件夹图像
• 我尝试在我的 php 系统文件中启用 phpfile 信息

没有任何效果。有什么帮助吗？作为一名开发人员，我已经 6 个月大了，所以如果提出愚蠢的问题，我深表歉意

类：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Color extends Model
{
    protected $fillable = [

        'namecol',
        'imgcol',

    ];

    public function products() {

        return $this -> hasMany(Product::class);
    }
}

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    protected $fillable = [

        'namepro',
        'imgpro',

    ];

    public function color() {

        return $this -> belongsTo(Color::class);
    }
}

迁移：

    public function up()
    {
        Schema::create('colors', function (Blueprint $table) {

            $table -> id();

            $table -> string('namecol', 100) -> unique();
            $table -> string('imgcol') -> nullable();

            $table -> timestamps();
        });
    }


    public function down()
    {
        Schema::dropIfExists('colors');
    }

        Schema::create('products', function (Blueprint $table) {

            $table -> id();

            $table -> string('namepro', 100);
            $table -> string('imgpro') -> nullable();

            $table -> bigInteger('color_id') -> unsigned();
            
            $table -> timestamps();
        }); 
    }

 
    public function down()
    {
        Schema::dropIfExists('products');
    }

    public function up()
    {
        Schema::table('products', function (Blueprint $table) {

            $table -> foreign('color_id', 'product-color')
                    -> references('id')
                    -> on('colors');

        });
    }


    public function down()
    {
        Schema::table('products', function (Blueprint $table) {
            $table->dropForeign('product-color');
        });
    }

创建和存储产品

    public function create() {

        $colors = Color::all();
        return view('pages.product-create', compact('colors'));
    }

    public function store(Request $request) {

        $data = $request -> all();


        $request->validate([
            'namepro' => 'required|min:3|max:100',
            'imgpro' => 'required|image|mimes:jpg,png,jpeg,gif,svg|max:2048',

        ]);

        $path = $request->file('imgpro')->store('public/images');
        $product = new Product;
        $product->namepro = $request->namepro;
        $product->imgpro = $path;



        $color = Color::findOrFail($data['color_id']);
        $product = Product::make($request -> all());
        $product -> color() -> associate($color);
        $product -> save();

        
        return redirect() -> route('product-show', $product -> id);
    }

视图中的表格

    <form action="{{ route('product-store') }}" method="POST" enctype="multipart/form-data"> 
        @csrf
        @method('POST')

        <label for="namepro">namepro</label>
        <input name="namepro" type="text">
        <br>

        <label for="imgpro">imgpro</label>
        <input name="imgpro" type="file">
        <br>


        <label for="color_id">color</label>
        <select name="color_id">
            @foreach ($colors as $color)
                <option value="{{ $color -> id }}">

                    {{$color -> namecol}}

                </option>
            @endforeach
        </select>
        <br>



        <input type="submit">

    </form>
