上传

在Swoft下通过 

\Swoft\Http\Message\Server\Request -> getUploadedFiles()['image']

方法可以获取到一个 Swoft\Http\Message\Upload\UploadedFile 对象或者对象数组（取决于上传时字段是image还是image[]）

打印改对象输出：

object(Swoft\Http\Message\Upload\UploadedFile)#1813 (6) {
       ["clientFilename":"Swoft\Http\Message\Upload\UploadedFile":private]=>  string(25) "蒙太奇配置接口.txt"  ["clientMediaType":"Swoft\Http\Message\Upload\UploadedFile":private]=>  string(10) "text/plain"  ["error":"Swoft\Http\Message\Upload\UploadedFile":private]=>  int(0)  ["tmpFile":"Swoft\Http\Message\Upload\UploadedFile":private]=>  string(55) "/var/www/swoft/runtime/uploadfiles/swoole.upfile.xZyq0d"  ["moved":"Swoft\Http\Message\Upload\UploadedFile":private]=>  bool(false)  ["size":"Swoft\Http\Message\Upload\UploadedFile":private]=>  int(710)}

都是私用属性，无法访问，但是可以通过对应方法访问到

getClientFilename()      //得到文件原名称getClientMediaType()     //得到文件类型getSize()        //获取到文件大小

通过方法

moveTo()      //将文件从临时位置转移到目录

上面方法返回为NULL，在移动文件到指定位置时最好判断一下文件夹是否存在，不存在创建

图片处理

借助  工具完成

ubuntu下一键安装

I. 安装ImageMagicksudo apt-get install imagemagickII. 安装imagemagick 的lib 供php调用sudo apt-get install libmagick++-devIII. 调用当前的pecl安装imagickpecl install imagickIV. 修改php.ini.重启nginx服务器在php.ini中添加: extension = imagick.so

在安装完成后修改完 /etc/php/7.0/cli/php.ini 后发现 phpinfo 页面打印出来没有出现下面信息，于是又修改了/etc/php/7.0/fpm/php.ini 才出现下面信息

安装 Intervention Image

composer require intervention/image

安装完成后可以直接在页面use

use Intervention\Image\ImageManager;$manager = new ImageManager(array('driver' => 'imagick'));//宽缩小到300px，高自适应$thumb = $manager->make($path)->resize(300, null, function ($constraint) {                $constraint->aspectRatio();});$thumb->save($path);

'/' . $file_name . '_thumb' .$ext_name;        $thumb->save($dir. '/' . $file_name . '_thumb' .$ext_name);        @chmod($thumb_path,0775);        return [            'url' => explode(alias('@public'),$path)[1],            'thumb_url' => explode(alias('@public'),$thumb_path)[1]        ];    }    /**     * 图片文件校验     * @param UploadedFile $file     * @return bool     */    protected static function checkImgFile(UploadedFile $file){        if($file->getSize() > 1024*1000*2){            throw new NotAcceptableException($file->getClientFilename().'文件大小超过2M');        }        if(!in_array($file->getClientMediaType(), self::$img_mime)){            throw new NotAcceptableException($file->getClientFilename().'类型不符');        }        return true;    }}

使用

FileController::imgUpload($request);

说明

当前保存文件路径为 alias("@upload")，需要在 /config/define.php 手动填上该路径

$aliases = [    '@root'       => BASE_PATH,    '@env'        => '@root',    '@app'        => '@root/app',    '@res'        => '@root/resources',    '@runtime'    => '@root/runtime',    '@configs'    => '@root/config',    '@resources'  => '@root/resources',    '@beans'      => '@configs/beans',    '@properties' => '@configs/properties',    '@console'    => '@beans/console.php',    '@commands'   => '@app/command',    '@vendor'     => '@root/vendor',    '@public'     => '@root/public',     //public目录，也是nginx设置站点根目录    '@upload'     => '@public/upload'    //上传目录];

Swoft 不提供静态资源访问，可以使用nginx托管

配置nginx 

vim /etc/nginx/sites-avaiable/default

server {        listen 80 default_server;        listen [::]:80 default_server;                # 域名设置        server_name eko.xiao.com;        #设置nginx根目录        root /var/www/html/swoft/public;        # 将所有非静态请求转发给 Swoft 处理        location / {            proxy_set_header X-Real-IP $remote_addr;            proxy_set_header Host $host;            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;            proxy_set_header Connection "keep-alive";            proxy_pass http://127.0.0.1:9501;        }        location ~ \.php$ {                proxy_pass http://127.0.0.1:9501;        }        # 静态资源使用nginx托管        location ~* \.(js|map|css|png|jpg|jpeg|gif|ico|ttf|woff2|woff)$ {            expires max;        }}
