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。
