laravel如何上传文件到七牛云

laravel如何上传文件到七牛云?

1:使用之前,先通过Composer安装:

composer require zgldh/qiniu-laravel-storage

如果执行过程中报以下错误:说明php没有开启扩展fileinfo,在php扩展开启fileinfo即可

Your requirements could not be resolved to an installable set of packages.
 
  Problem 1
    - stevenyangecho/laravel-u-editor v1.4.2 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
    - stevenyangecho/laravel-u-editor v1.4.1 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
    - stevenyangecho/laravel-u-editor v1.4.0 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
    - Installation request for stevenyangecho/laravel-u-editor ~1.4 -> satisfiable by stevenyangecho/laravel-u-editor[v1.4.0, v1.4.1, v1.4.2].
 
  To enable extensions, verify that they are enabled in your .ini files:
    - F:\phpStudy\PHPTutorial\php\php-7.2.1-nts\php.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.
 
Installation failed, reverting ./composer.json to its original content.

2:然后在 config/app.php providers 中注册服务提供者:

zgldh\QiniuStorage\QiniuFilesystemServiceProvider::class

3:接下来在config/filesystems.php里的disks中新增如下选项:

'disks' => [
        ... ,
        'qiniu' => [
            'driver'  => 'qiniu',
            'domains' => [
               'default'   => 'xxxxx', //你的七牛域名
        'https'     => 'xxxxx',//你的HTTPS域名
        'custom'    => 'xxxxx',//你的自定义域名
             ],
            'access_key'=> 'IKYPvIRNQRxahzSzQh-9nf0er--4oTCzkeIWQM4X',  //AccessKey
    'secret_key'=> '3KfIusCaWrJGiJnR1kvX6y3UJ1CyBbDHVK7Nm1xi',  //SecretKey
    'bucket'    => '1805a',  //Bucket名字
    'notify_url'=> 'http://www.zb.cn/lx',  //持久化处理回调地址
        ],
    ],

4: OK,扩展包的安装就暂时介绍到这里,接下来我们要去七牛注册一个账号并且将上面的配置完善。

七牛账号注册及配置

先去七牛注册一个账号,点击官网的注册会让我们选择用户类型,这里我就选择个人用户,接下来按照流程来进项注册就OK了.

点击秘钥管理,就可与看到个人七牛的秘钥了:

七牛在Laravel中的配置

上面已经介绍相关的配置在哪儿,现在我们要将这些配置在Laravel中使用:

先在 resources\views 下新建 image.blade.php 视图

<!DOCTYPE html>
<html>
<head>
    <title>上传图片</title>
</head>
<body>
    <form method="post" action="" enctype="multipart/form-data">
        <input type="file" name="file">
        <button type="submit">上传图片</button>
    </form>
</body>
</html>

实现上传方法:控制器

<?php
 
namespace App\Http\Controllers;
 
use zgldh\QiniuStorage\QiniuStorage;  //调用基类
use Illuminate\Http\Request;
//七牛云图片上传
class lxController extends Controller
{
    public function index(Request $request){
    if ($request->isMethod('post')) {
     // 判断是否有文件上传
        if ($request->hasFile('file')) {
            // 获取文件,file对应的是前端表单上传input的name
            $file = $request->file('file');
            // Laravel5.3中多了一个写法
            // $file = $request->file;
 
            // 初始化
            $disk = QiniuStorage::disk('qiniu');
            // 重命名文件
            $fileName = md5($file->getClientOriginalName().time().rand()).'.'.$file->getClientOriginalExtension();
 
            // 上传到七牛
            $bool = $disk->put('iwanli/image_'.$fileName,file_get_contents($file->getRealPath()));
            // 判断是否上传成功
            if ($bool) {
                $path = $disk->downloadUrl('iwanli/image_'.$fileName);
                return '上传成功,图片url:'.$path; 
            }
            return '上传失败';
        }
        return '没有文件';
}else{
return view('lx.image');
}
    }
}

OK,刷新页面就能看到上传后的url地址了。这里只是演示一个最简单的实例,路由定义、视图样式、及逻辑层处理大家按照自己的项目的需求即可。
