PHP 上传文件至阿里云OSS对象存储

简述

1、阿里云开通对象存储服务 OSS 并创建Bucket
2、下载PHP SDK至框架扩展目录，点我下载
3、码上code

阿里云操作

开通对象存储服务 OSS

创建 Bucket

配置AccessKey与Access Key Secret

进入管理AccessKey页面 (可将鼠标放在右上角用户头像上，在弹出来的框中点击AccessKey 管理)

找到Bucket对应的外网访问节点

下载 PHP SDK

点我下载

SDK 参考

API参考

SDK 下载完成后放入框架对应的扩展目录

上码

config配置

//阿里云OSS配置
\'alioss\'        =>[
    \'AccessKeyID\'      => \'AccessKey ID\',
    \'AccessKeySecret\'  => \'Access Key Secret\',
    \'EndPoint\'   => \'外网访问地域节点\',
    \'Bucket\'     => \'Bucket 名称\', 
],

后端结合SDK实现文件上传至阿里云OSS

以ThinkPHP5为例

<?php
namespace app\controller;

use think\Controller;
use think\Image;

require_once APP_PATH . \'/../extend/aliyun-oss/autoload.php\'; //引入阿里云OSS SDK，注意替换路径
use OSS\Core\OssException;
use OSS\OssClient;

class AliOssUpload
{

    /**
     * 文件上传接口
     * 
     */
    public function uploadFile()
    {
        //接收上传文件
        $file = $this->request->file(\'file\');
        $res = [];
        if($file){
            //调用阿里云OSS上传
            $res = self::AliuploadFile(\'img\', $file);
            if ($res[\'code\'] == 200) {
                //业务逻辑处理......
            }
        }else{
            $res[\'code\']=0;
            $res[\'msg\']=\'没有上传文件\';
        }
        return json($res);
    }

    /**
     * 调用阿里云OSS SDK
     * @param $module 模块
     * @param $file 上传的文件
     * @return array 阿里云OSS上传处理结果
     * 
     */
    public static function AliuploadFile($module, $file)
    {
        $resResult = Image::open($file);
        try {
            //获取OSS参数值
            $KeyId = config(\'alioss.AccessKeyID\');
            $KeySecret = config(\'alioss.AccessKeySecret\');
            $EndPoint = config(\'alioss.EndPoint\');
            $Bucket = config(\'alioss.Bucket\');
            //实例化
            $ossClient = new OssClient($KeyId, $KeySecret, $EndPoint);
            //sha1加密 生成文件名 连接后缀
            $fileName = $module . \'/\' . sha1(date(\'YmdHis\', time()) . uniqid()) . \'.\' . $resResult->type();
            //执行阿里云上传
            $result = $ossClient->uploadFile($Bucket, $fileName, $file->getInfo()[\'tmp_name\']);
            //图片地址:$result[\'info\'][\'url\']
            $arr = [\'code\' => 200, \'msg\' => \'上传成功\', \'data\' => $result[\'info\'][\'url\']];
        } catch (OssException $e) {
            $arr = [\'code\' => 0, \'msg\' => $e->getMessage(), \'data\' => \'\'];
        }
        return $arr;
    }
}

前端参考代码

前端使用layui，谨慎参考

<div class="layui-upload" id="upload-thumb">
    <label class="layui-form-label">缩略图</label>
    <button type="button" class="layui-btn" id="thumb">上传图片</button>
    <div class="layui-upload-list">
        <label class="layui-form-label"></label>
        <img class="layui-upload-img" id="demo1" width="150" height="150">
        <p id="demoText"></p>
    </div>
</div>




<script>
    //上传图片接口
    layui.use(\'upload\', function(){
        var upload = layui.upload;
        //执行实例
        var uploadInst = upload.render({
            elem: \'#thumb\' //绑定元素
            ,url: "{:url(\'AliOssUpload/uploadFile\')}" //上传接口
            ,data:{use:\'article_thumb\'}
            ,done: function(res){
                //上传完毕回调
                if(res.code == 200) {
                    //前台显示预览图
                    $(\'#demo1\').attr(\'src\',res.data);
                    $(\'#upload-thumb\').append(\'<input type="hidden" name="thumb" value="\'+ res.data +\'">\');
                } else {
                    layer.msg(res.msg);
                }
            }
            ,error: function(){
                //请求异常回调
                //演示失败状态，并实现重传
                var demoText = $(\'#demoText\');
                demoText.html(\'<span style="color: #FF5722;">上传失败</span> <a class="layui-btn layui-btn-mini demo-reload">重试</a>\');
                demoText.find(\'.demo-reload\').on(\'click\', function(){
                    uploadInst.upload();
                });
            }
        });
    });
