请确认上传文件的路径是否有值。即

$_FILES['input-file-name']['tmp_name']

七牛云代码定位如下：

public function putFile(
        $upToken,
        $key,
        $filePath,
        $params = null,
        $mime = 'application/octet-stream',
        $checkCrc = false
    ) {
        $file = fopen($filePath, 'rb'); //文件不存在，或者不可读
        if ($file === false) { //文件为空
            throw new \Exception("file can not open", 1); //抛出错误的地方
        }
        $params = self::trimParams($params);
        $stat = fstat($file);
        $size = $stat['size'];
        if ($size config,
                $params,
                $mime,
                $checkCrc
            );
        }
        $up = new ResumeUploader(
            $upToken,
            $key,
            $file,
            $size,
            $params,
            $mime,
            $this->config
        );
        $ret = $up->upload();
        fclose($file);
        return $ret;
    }
