为什么 laravel 中的图片文件上传 url 给我一个 404 错误？

Question

我已经构建了一个简单的后端结构，其中包含创建、编辑、更新、查看，就像您通常使用 mvc 和 laravel 进行设置一样。我正在使用的软件包是：

"require": {
        "php": ">=5.5.9",
        "laravel/framework": "5.1.*",
        "illuminate/html": "5.*",
        "codesleeve/laravel-stapler": "dev-master",
        "intervention/image": "^2.3",
        "dingo/api": "0.9.*"
    },
    "require-dev": {
        "fzaninotto/faker": "~1.4",
        "mockery/mockery": "0.9.*",
        "phpunit/phpunit": "~4.0",
        "phpspec/phpspec": "~2.1",
        "laracasts/generators": "^1.1",
        "way/generators": "~3.0"
    },

它在向表单添加数据和更新时起作用。数据结构如下：

"id": 1,
"name": "new offer",
"address": "test address",
"description": "test",
"offer_headline": "ccdd",
"offer_subheader": "hhhghhg",
"offer_terms": "test",
"map_location": "14,57",
"image": "/home/vagrant/projects/scoff/scoff-api/storage/app/uploads/2015-07-28-14:16:10-Screen Shot 2014-09-11 at 10.26.15.png",
"phone_number": "**************",
"website": "www.****.uk",
"created_at": "2015-07-28 14:16:10",
"updated_at": "2015-07-28 14:16:10",
"is_featured": false

执行此操作的控制器以非常简单的方式使用 store 方法进行设置，如下所示。我的图像上传由 laravel 文件系统中的 Store 处理，我使用图像干预来调整图像大小。如您所见，图像已保存到数据库中，数据库中的 url 是这样的：/home/vagrant/projects/scoff/scoff-api/storage/app/uploads/ 问题是当我去查找器查找文件时，它不存在或没有被移动。我的控制器在下面：

我已经在相关部分留下了这个

        if ($validation->fails()) {

        $offer->update($input);

        return Redirect::route('offers.show',$offer->id)->with('message', 'Offer updated.');
    }

}

谁能明白为什么会发生这种情况？是不是被移到了正确的地方？

每 cmets 再次更新。

您似乎正在将文件保存到通常不公开的存储区域。尝试将storage_path 更改为public_path。然后，您可以获取相对路径并将其存储在数据库中。

$relativePath = 'app/uploads/'.sanitize_file($filename);
Image::make($file->getRealPath())
  ->resize(600, 600)
  ->save(public_path().$relativePath);

$data['image'] = '/'.$relativePath;

您需要chmod 755 或chmod 775 上传文件夹以允许服务器将文件保存在那里，这通常是个坏主意，但人们会这样做。

我通常做的是使用云存储将图像保存到S3，然后从CloudFront 提供它们。所以我不能 100% 确定我会在同一个 Web 服务器上为他们提供什么服务。

我忘记了 str_slug 也会删除 .。我使用这个辅助函数来清理文件。

if (!function_exists('sanitize_file')) {
    function sanitize_file($string, $force_lowercase = true, $anal = false)
    {
        $strip = array("~", "`", "!", "@", "#", "$", "%", "^", "&", "*", 
                       "(", ")", "_", "=", "+", "[", "{", "]", "}", "\\",
                       "|", ";", ":", "\"", "'", "‘", "’",
                       "“", "”", "–", "—",
                       "—", "–", ",", "<", ">", "/", "?");
        $clean = trim(str_replace($strip, "", strip_tags($string)));
        $clean = preg_replace('/\s+/', "-", $clean);
        $clean = ($anal) ? preg_replace("/[^a-zA-Z0-9]/", "", $clean) : $clean;
        return ($force_lowercase) ?
            (function_exists('mb_strtolower')) ?
                mb_strtolower($clean, 'UTF-8') :
                strtolower($clean) :
            $clean;
    }
}
