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 ImageMagick 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);完整代码
namespace App\Controllers\Api;use Intervention\Image\ImageManager;use Swoft\Http\Message\Server\Request;use Swoft\Http\Message\Upload\UploadedFile;use Swoft\Http\Server\Exception\NotAcceptableException;use Swoft\Http\Server\Bean\Annotation\Controller;use Swoft\Http\Server\Bean\Annotation\RequestMapping;use Swoft\Http\Server\Bean\Annotation\RequestMethod;class FileController{ ???//图片可接受的mime类型 ???private static $img_mime = [‘image/jpeg‘,‘image/jpg‘,‘image/png‘,‘image/gif‘]; ???/** ????* 文件上传 ????* @RequestMapping(route="image",method=RequestMethod::POST) ????*/ ???public static function imgUpload(Request $request){ ???????$files = $request->getUploadedFiles()[‘image‘]; ???????if(!$files){ ??????????throw new NotAcceptableException(‘image字段为空‘); ???????} ???????if(is_array($files)){ ???????????$result = array(); ???????????foreach ($files as $file){ ???????????????self::checkImgFile($file); ???????????????$result[] = self::saveImg($file); ???????????} ???????}else{ ???????????self::checkImgFile($files); ???????????return self::saveImg($files); ???????} ???} ???/** ????* 保存图片 ????* @param UploadedFile $file ????*/ ???protected static function saveImg(UploadedFile $file){ ???????$dir = alias(‘@upload‘) . ‘/‘ . date(‘Ymd‘); ???????if(!is_dir($dir)){ ???????????@mkdir($dir,0777,true); ???????} ???????$ext_name = substr($file->getClientFilename(), strrpos($file->getClientFilename(),‘.‘)); ???????$file_name = time().rand(1,999999); ???????$path = $dir . ‘/‘ . $file_name . $ext_name; ???????$file->moveTo($path); ???????//修改移动后文件访问权限，文件默认没有访问权限 ???????@chmod($path,0775); ???????//生成缩略图 ???????$manager = new ImageManager(array(‘driver‘ => ‘imagick‘)); ???????$thumb = $manager->make($path)->resize(300, null, function ($constraint) { ???????????$constraint->aspectRatio(); ???????}); ???????$thumb_path = $dir. ‘/‘ . $file_name . ‘_thumb‘ .$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; ???????}}Swoft 图片上传与处理
