Laravel 5.4 Intevention Image Not Readable 图像可读时出现异常

Question

我正在学习 Laravel 5.4 的干预图像包。我的公共/图像文件夹中存储了一张图像。

我根据干预页面上的说明安装了 Image：向我的 composer.json 文件添加干预，运行 composer update，更新我的配置/应用程序文件，并运行 composer dump-autoload。

• 当直接作为图片访问时（代码中的printf语句 下面的块）图像显示。

• 使用 make 方法，我在 AbstractDecoder.php.

有没有人看到我在代码中做错了什么或者可能错过了安装步骤？

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Intervention\Image\Facades\Image;

class TestController extends Controller
{
    public function imagetest()
    {
        printf('<img src="/images/j6.jpg">'); //correctly displays image on page

        $img = Image::make("/images/j6.jpg")->resize(300, 200); //throws the error
        return $img->response('jpg');
    }
}

这里是“printf”图像之后页面上的错误块的引导：

Whoops, looks like something went wrong.

你需要在你的文件系统中提供图片文件的完整路径。从你的图片标签来看，图片应该在你的webroot的images文件夹中。你可以这样做。

$imagePath = public_path('images/j6.jpg');
$img = Image::make($imagePath)->resize(300, 200);
