### 需要composer引入图像处理扩展 `composer require topthink/think-image` 引入类 `use think\Config as FaConfig;` ``` /** * 上传文件 * @ApiMethod (POST) * @param File $file 文件流 */ public function upload() { $file = $this->request->file('file'); if (empty($file)) { $this->error(__('No file upload or server upload limit exceeded')); } //判断是否已经存在附件 $sha1 = $file->hash(); $upload = FaConfig::get('upload'); preg_match('/(\d+)(\w+)/', $upload['maxsize'], $matches); $type = strtolower($matches[2]); $typeDict = ['b' => 0, 'k' => 1, 'kb' => 1, 'm' => 2, 'mb' => 2, 'gb' => 3, 'g' => 3]; $size = (int)$upload['maxsize'] * pow(1024, isset($typeDict[$type]) ? $typeDict[$type] : 0); $fileInfo = $file->getInfo(); $suffix = strtolower(pathinfo($fileInfo['name'], PATHINFO_EXTENSION)); $suffix = $suffix && preg_match("/^[a-zA-Z0-9]+$/", $suffix) ? $suffix : 'png'; //验证是否为图片文件 $imagewidth = $imageheight = 0; if (in_array($fileInfo['type'], ['image/gif', 'image/jpg', 'image/jpeg', 'image/bmp', 'image/png', 'image/webp']) || in_array($suffix, ['gif', 'jpg', 'jpeg', 'bmp', 'png', 'webp'])) { $imgInfo = getimagesize($fileInfo['tmp_name']); if (!$imgInfo || !isset($imgInfo[0]) || !isset($imgInfo[1])) { $this->error(__('Uploaded file is not a valid image')); } $imagewidth = isset($imgInfo[0]) ? $imgInfo[0] : $imagewidth; $imageheight = isset($imgInfo[1]) ? $imgInfo[1] : $imageheight; } $replaceArr = [ '{year}' => date("Y"), '{mon}' => date("m"), '{day}' => date("d"), '{hour}' => date("H"), '{min}' => date("i"), '{sec}' => date("s"), '{random}' => Random::alnum(16), '{random32}' => Random::alnum(32), '{filename}' => $suffix ? substr($fileInfo['name'], 0, strripos($fileInfo['name'], '.')) : $fileInfo['name'], '{suffix}' => $suffix, '{.suffix}' => $suffix ?
