将静态内容保存到Laravel公用文件夹中

Question

I am having trouble storing images in the 'public' folder of the Laravel framework (which I believe is the static content folder? Please correct me if I am wrong).

I am running a seed using faker which generates images and stores the images URL's in a table. This is all working correctly but the seed itself keeps failing as it can't seem to access or find the folder within the public folder I have created. This is my public folder structure:

/public/assets/images

And here is my seed which should save my images into this folder:

<?php

use Illuminate\Database\Seeder;

class ProductsTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        DB::table('products')->truncate();

        $faker = Faker\Factory::create();

        $limit = 30;

        for($i = 0; $i < $limit; $i++) {
            DB::table('products')->insert([
                'title'       => $faker->name,
                'SKU'         => $faker->name,
                'description' => $faker->text,
                'created_at'  => $faker->dateTime,
                'updated_at'  => $faker->dateTime,
                'images'      => $faker->image(URL::to(Config::get('assets.images')) ,800, 600, [], [])
            ]);
        }
    }
}#

The 'assets.images' config file is:

<?php
    return [
        'images' => '/assets/images'   
    ];

When I try and run the seed to populate my database I get the following error:

  [InvalidArgumentException]                                       
  Cannot write to directory "http://localhost:8931/assets/images"  

I cannot see where I am going wrong. Can anyone offer any insight?

Answer 1

使用辅助函数public_path（）更改对URL :: to的调用，如下所示：

$faker->image(public_path(Config::get('assets.images')) ,800, 600, [], [])

Answer 2

I'm not a laravel expert, but the thrown exception looks like you're trying to write to an url rather than a file path on the disk.

Maybe you want to check if the process owner running the php script has write access to that location.
