腾讯云Cos云存储Thinkphp使用方法

1、首先在项目当中利用Composer下载Cos的包

composer require qcloud/cos-sdk-v5

2、然后查看以下案例

<?php namespace appqiugongcontroller; use thinkfacadeDb; use thinkfacadeRequest; /**
 * Class Cos
 * 腾讯云Cos云存储
 * Developers:ZhouQiugong
 * @package apphomecontroller
 */ class Cos extends Base { // SecretId protected $SecretId = "xxxxx"; // SecretKey protected $SecretKey = "xxxxxx"; // Bucket protected $bucket = "xxxxxxx"; /**
     * 初始化 Cos
     * Developers:ZhouQiugong
     * @return QcloudCosClient
     */ public function initCos() { $cosClient = new QcloudCosClient([ 'region' => 'ap-guangzhou', //设置一个默认的存储桶地域 'schema' => 'http', //协议头部，默认为http 'credentials' => ['secretId' => $this->SecretId, 'secretKey' => $this->SecretKey] ]); return $cosClient; } /**
     * Base64上传cos
     * Developers:ZhouQiugong
     * @return 	hink
esponseJson
     */ public function upload() { // 上传Base64图片 $imgBase64 = input('base64'); if (preg_match('/^(data:s*image/(w+);base64,)/', $imgBase64, $res)) { // 图片大小 $size = file_get_contents($imgBase64); // 获取图片类型 $type = $res[2]; // 文件 $fileName = '/' . date('Ymd') . '/' . md5(time() . rand(1000, 9999)) . '.' . $type; //截取data:image/png;base64, 这个逗号后的字符 $base64_string = explode(',', $imgBase64); //对截取后的字符使用base64_decode进行解码 $tmp_name = base64_decode($base64_string[1]); // 初始化Cos $cosClient = $this->initCos(); // 拼接COS请求数据包 $data = ['Bucket' => $this->bucket, 'Key' => $fileName, 'Body' => $tmp_name]; // 执行Cos上传操作 $result = $cosClient->Upload($data['Bucket'], $data['Key'], $data['Body']); // 将保存在Cos的图片记录保存到数据库 Db::name('cos_files')->insert([ 'file_name' => $result['Key'], 'url' => $result['Location'], 'size' => strlen($size) / 1024, 'status' => 1, 'time' => time() ]); // 拼接地址返回前端 $url = "https://xxx.xxx.com/" . $result['Key']; // 输出到前端 return json(['status' => 200, 'msg' => '上传成功', 'url' => $url]); } } /**
     * Cos 删除单个文件
     * Developers:ZhouQiugong
     * @param $key
     * @return 	hink
esponseJson
     * @throws 	hinkException
     * @throws 	hinkexceptionPDOException
     */ public function delFile($key) { $bucket = $this->bucket; $cosClient = $this->initCos(); $result = $cosClient->deleteObject(['Bucket' => $bucket, 'Key' => $key]); if ($result) { Db::name('cos_files')->where(['file_name' => $key, 'status' => 1])->delete(); return json(['status' => 200, 'msg' => '删除成功']); } else { return json(['status' => 500, 'msg' => '删除失败']); } } }
