PHP COS图片文件上传

TP5框架使用composer命令安装vendor目录
composer require tencentcloud/tencentcloud-sdk-php
composer require qcloud/cos-sdk-v5
在application/common目录下新建一个cos目录,新建一个类文件CosSdk.php
<?php
namespace app\common\cos;
class CosSdk {
//腾讯云cos配置信息
public  $QCLOUD = array(
    'appId'     => '',   //账户中心的 APPid
    'SecretId'  => '',   //开发者拥有的项目身份识别 ID
    'SecretKey' => '',   //开发者拥有的项目身份密钥
    'region'    => '',   //你的Bucket所有地域
    'bucket'    => ''    //COS中用于存储桶名称
);
public function __construct()
{
    //引入sdk
    \think\Loader::import('CosSdk.vendor.autoload');
    $this->appId      =$this->QCLOUD['appId'];//账户中心的 APPid
    $this->SecretId   =$this->QCLOUD['SecretId'];//开发者拥有的项目身份识别 ID
    $this->SecretKey  =$this->QCLOUD['SecretKey']; //开发者拥有的项目身份密钥
    $this->region     =$this->QCLOUD['region'];//你的Bucket所有地域 例如上海 (sh)写简称就可以
