首先 获取图片上传的地址和凭证  结合上一篇文章

$imageId = self::createUpload();#获取图片上传地址和凭证
 
$uploadAuthThree = json_decode(base64_decode($imageId->body->uploadAuth),true);
$uploadAddressThree = json_decode(base64_decode($imageId->body->uploadAddress),true);
 
$localFileThree = $_SERVER['DOCUMENT_ROOT'].'/uploads/20210409/eab2309c3f59974227a1dbee513b302c.png';
 
$ossClient = self::initOssClient($uploadAuthThree,$uploadAddressThree,$localFileThree);#基于OSS原生SDK上传图片
 
 
    /**

    public static function createUpload(){
        $client = self::createClient("", "");
        $createUploadImageRequest = new CreateUploadImageRequest([
            "imageType" => "cover"#封面
        ]);
        // 复制代码运行请自行打印 API 的返回值
        return $client->createUploadImage($createUploadImageRequest);
    }
