23、Hyperf 3 快速使用 - Hyperf 3 上传文件 or 图片到腾讯云
hi，我是温新，一名 PHPer
Hypref 版本：Hyperf 3.0
学习目标：掌握上传文件 or 图片到腾讯云
本篇文章学习的是将文件上传到阿里云。在此之前需要准备好阿里云的对象存储空间。
准备工作
第一步：安装组件
composer require hyperf/filesystem
composer require "overtrue/flysystem-cos:^5.0"
第二步：生成配置文件
php bin/hyperf.php vendor:publish hyperf/filesystem
该命令会在 config/autoload 目录下生成 file.php 文件，其中关于七牛云的配置如下：
<?php
'cos' => [
'driver' => \Hyperf\Filesystem\Adapter\CosAdapterFactory::class,
'region' => env('COS_REGION'),
'app_id' => env('COS_APPID'),
'secret_id' => env('COS_SECRET_ID'),
'secret_key' => env('COS_SECRET_KEY'),
// 可选，如果 bucket 为私有访问请打开此项
// 'signed_url' => false,
'bucket' => env('COS_BUCKET'),
'read_from_cdn' => false,
// 'timeout' => 60,
// 'connect_timeout' => 60,
// 'cdn' => '',
'scheme' => 'https',
'domain'=>'访问图片的域名', // 不加 http/https
],
第三步：.env 文件中填写配置
// .env
COS_REGION=ap-guangzhou
COS_APPID=腾讯云账号 APPID
COS_SECRET_ID=腾讯云 KEY
COS_SECRET_KEY=腾讯云 SECRET
COS_BUCKET=bucket
第四步：创建控制器
<?php
namespace App\Controller\Test;
use Hyperf\HttpServer\Annotation\Controller;
#[Controller]
class TxUploadController
{
}
上传图片到腾讯云
方法一：通过实例方式上传
上传图片案例
<?php
//App\Controller\Test\TxUploadController.php
use Hyperf\Contract\ConfigInterface;
use Hyperf\Filesystem\FilesystemFactory;
use Hyperf\HttpServer\Annotation\Controller;
use Hyperf\HttpServer\Annotation\PostMapping;
use Hyperf\Utils\ApplicationContext;
use League\Flysystem\Config;
#[PostMapping('/tx/store')]
public function store()
{
$path = 'a.jpg';
$container = ApplicationContext::getContainer();
$options = $container->get(ConfigInterface::class)->get('file');
$filesystemFactory = $container->get(FilesystemFactory::class);
$adapter = $filesystemFactory->getAdapter($options, 'cos');
if ($adapter->fileExists('hyperf/' . $path)) {
return 'exists';
}
$adapter->writeStream('hyperf/' . $path, fopen($path, 'r'), new Config());
return 'succ';
}
方法二：使用依赖注入
1、通过 Hyperf\Filesystem\FilesystemFactory; 实现
第一步：控制器
<?php
namespace App\Controller\Test;
use Hyperf\Contract\ConfigInterface;
use Hyperf\Contract\ContainerInterface;
use Hyperf\Filesystem\FilesystemFactory;
use Hyperf\HttpServer\Annotation\Controller;
use Hyperf\HttpServer\Annotation\GetMapping;
use Hyperf\HttpServer\Annotation\PostMapping;
use Hyperf\HttpServer\Contract\RequestInterface;
use Hyperf\View\RenderInterface;
use League\Flysystem\Config;
use League\Flysystem\FilesystemAdapter;
#[Controller]
class TxUploadController
{
protected FilesystemAdapter $adapter;
public function __construct(protected ContainerInterface $container, $adapterName = 'cos')
{
$this->adapter = $this->getAdapter($adapterName);
}
public function getAdapter($adapterName)
{
$options = $this->container->get(ConfigInterface::class)->get('file');
$filesystemFactory = $this->container->get(FilesystemFactory::class);
return $filesystemFactory->getAdapter($options, $adapterName);
}
#[GetMapping('/tx/create')]
public function create(RenderInterface $render)
{
return $render->render('txoss.create');
}
#[PostMapping('/tx/store')]
public function store(RequestInterface $request)
{
if ($request->hasFile('file')) {
$file = $request->file('file');
$newFilename = 'hyperf/' . date('YmdHis') . uniqid() . '.' . $file->getExtension();
$stream = fopen($file->getRealPath(), 'r');
$this->adapter->writeStream($newFilename, $stream, new Config());
return '图片上传成功';
}
}
}
第二步：视图文件
<!-- storage/txoss/create.blade.php -->
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>COS</title>
</head>
<body>
<form method="post" action="/tx/store" enctype="multipart/form-data">
<input type="file" name="file">
<input type="submit" value="上传图片">
</form>
</body>
</html>
2、使用 \League\Flysystem\Filesystem $filesystem 对象实现
这一步只修改修改控制器对的方法即可，如下：
<?php
namespace App\Controller\Test;
use Hyperf\Contract\ConfigInterface;
use Hyperf\Contract\ContainerInterface;
use Hyperf\Filesystem\FilesystemFactory;
use Hyperf\HttpServer\Annotation\Controller;
use Hyperf\HttpServer\Annotation\GetMapping;
use Hyperf\HttpServer\Annotation\PostMapping;
use Hyperf\HttpServer\Contract\RequestInterface;
use Hyperf\View\RenderInterface;
use League\Flysystem\Config;
use League\Flysystem\Filesystem;
use League\Flysystem\FilesystemAdapter;
#[Controller]
class TxUploadController
{
protected FilesystemAdapter $adapter;
protected $filesystem;
public function __construct(protected ContainerInterface $container, $adapterName = 'cos')
{
$this->adapter = $this->getAdapter($adapterName);
// 改动
$this->filesystem = new Filesystem($this->adapter);
}
public function getAdapter($adapterName)
{
$options = $this->container->get(ConfigInterface::class)->get('file');
$filesystemFactory = $this->container->get(FilesystemFactory::class);
return $filesystemFactory->getAdapter($options, $adapterName);
}
#[GetMapping('/tx/create')]
public function create(RenderInterface $render)
{
return $render->render('txoss.create');
}
#[PostMapping('/tx/store')]
public function store(RequestInterface $request)
{
if ($request->hasFile('file')) {
$file = $request->file('file');
$newFilename = 'hyperf/' . date('YmdHis') . uniqid() . '.' . $file->getExtension();
$stream = fopen($file->getRealPath(), 'r');
// 改动
$this->filesystem->writeStream($newFilename, $stream);
return '图片上传成功';
}
}
}
