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ImageMagick
sudo apt-get install imagemagick
II. 安装imagemagick 的lib 供php调用
sudo apt-get install libmagick++-dev
III. 调用当前的pecl安装imagick
pecl install imagick
IV. 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;

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);
}
}
/**

*/
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
