当前,我正在尝试从数据库表中检索图像,但是没有成功。我已经制作了一个表格,在其中插入了图像,以便可以检索它。
我在堆栈溢出中寻找问题的答案。有相似的问题,但答案不是我要找的答案。我也在Laracast网站上寻找了答案,但是这些答案没有提供解决方案。
我的观点:
@extends ('Layout')
@section('title')
Galerij

@section('content')

我的模特:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class gallerij extends Model
{
protected $fillable=[
'afbeelding', 'id'
];
}
我的create_gallerij__table.php:
<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateGallerijTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('gallerij', function (Blueprint $table) {
$table->bigIncrements('id');
$table->binary('afbeelding');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('gallerij');
}
}
希望我已经给您足够的信息来帮助我找到解决方案。

要显示二进制文件,必须使用base64_encode()函数。
尝试一下:
控制器
$g = Gallerij::find(1);
$image = chunk_split(base64_encode($g->afbeelding));
查看
<img src="data:image/png;base64,{{ $image }}">
