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：
1object(Swoft\Http\Message\Upload\UploadedFile)#1813 (6) { 2 ["clientFilename":"Swoft\Http\Message\Upload\UploadedFile":private]=> 3 string(25) "蒙太奇配置接口.txt" 4 ["clientMediaType":"Swoft\Http\Message\Upload\UploadedFile":private]=> 5 string(10) "text/plain" 6 ["error":"Swoft\Http\Message\Upload\UploadedFile":private]=> 7 int(0) 8 ["tmpFile":"Swoft\Http\Message\Upload\UploadedFile":private]=> 9 string(55) "/var/www/swoft/runtime/uploadfiles/swoole.upfile.xZyq0d" 10 ["moved":"Swoft\Http\Message\Upload\UploadedFile":private]=> 11 bool(false) 12 ["size":"Swoft\Http\Message\Upload\UploadedFile":private]=> 13 int(710) 14}
都是私用属性，无法访问，但是可以通过对应方法访问到
1getClientFilename() //得到文件原名称 2getClientMediaType() //得到文件类型 3getSize() //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
1I. 安装ImageMagick 2sudo apt-get install imagemagick 3 4II. 安装imagemagick 的lib 供php调用 5sudo apt-get install libmagick++-dev 6 7III. 调用当前的pecl安装imagick 8pecl install imagick 9 10IV. 修改php.ini.重启nginx服务器 11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
1use Intervention\Image\ImageManager; 2 3$manager = new ImageManager(array('driver' => 'imagick')); 4//宽缩小到300px，高自适应 5$thumb = $manager->make($path)->resize(300, null, function ($constraint) { 6 $constraint->aspectRatio(); 7}); 8$thumb->save($path);
完整代码
1namespace App\Controllers\Api; 2 3use Intervention\Image\ImageManager; 4use Swoft\Http\Message\Server\Request; 5use Swoft\Http\Message\Upload\UploadedFile; 6use Swoft\Http\Server\Exception\NotAcceptableException; 7use Swoft\Http\Server\Bean\Annotation\Controller; 8use Swoft\Http\Server\Bean\Annotation\RequestMapping; 9use Swoft\Http\Server\Bean\Annotation\RequestMethod; 10 11 12class FileController 13{ 14 //图片可接受的mime类型 15 private static $img_mime = ['image/jpeg','image/jpg','image/png','image/gif']; 16 17 /** 18 * 文件上传 19 * @RequestMapping(route="image",method=RequestMethod::POST) 20 */ 21 public static function imgUpload(Request $request){ 22 $files = $request->getUploadedFiles()['image']; 23 if(!$files){ 24 throw new NotAcceptableException('image字段为空'); 25 } 26 27 if(is_array($files)){ 28 $result = array(); 29 foreach ($files as $file){ 30 self::checkImgFile($file); 31 $result[] = self::saveImg($file); 32 } 33 }else{ 34 self::checkImgFile($files); 35 return self::saveImg($files); 36 } 37 38 } 39 40 /** 41 * 保存图片 42 * @param UploadedFile $file 43 */ 44 protected static function saveImg(UploadedFile $file){ 45 $dir = alias('@upload') .

使用
FileController::imgUpload($request);
说明
当前保存文件路径为 alias("@upload")，需要在 /config/define.php 手动填上该路径
1$aliases = [ 2 '@root' => BASE_PATH, 3 '@env' => '@root', 4 '@app' => '@root/app', 5 '@res' => '@root/resources', 6 '@runtime' => '@root/runtime', 7 '@configs' => '@root/config', 8 '@resources' => '@root/resources', 9 '@beans' => '@configs/beans', 10 '@properties' => '@configs/properties', 11 '@console' => '@beans/console.php', 12 '@commands' => '@app/command', 13 '@vendor' => '@root/vendor', 14 '@public' => '@root/public', //public目录，也是nginx设置站点根目录 15 '@upload' => '@public/upload' //上传目录 16];
Swoft 不提供静态资源访问，可以使用nginx托管
配置nginx
1vim /etc/nginx/sites-avaiable/default 2 3server { 4 listen 80 default_server; 5 listen [::]:80 default_server; 6 7 # 域名设置 8 server_name eko.xiao.com; 9 #设置nginx根目录 10 root /var/www/html/swoft/public; 11 12 # 将所有非静态请求转发给 Swoft 处理 13 location / { 14 proxy_set_header X-Real-IP $remote_addr; 15 proxy_set_header Host $host; 16 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 17 proxy_set_header Connection "keep-alive"; 18 proxy_pass http://127.0.0.1:9501; 19 } 20 21 location ~ \.php$ { 22 proxy_pass http://127.0.0.1:9501; 23 } 24 # 静态资源使用nginx托管 25 location ~* \.(js|map|css|png|jpg|jpeg|gif|ico|ttf|woff2|woff)$ { 26 expires max; 27 } 28}
