如何使用Perfect 2.0 swift上传文件？

import PerfectHTTP
import PerfectHTTPServer

// 创建一个路由处理程序
let uploadHandler: Routing.Handler = { request, response in
    // 获取上传的文件
    guard let uploads = request.fileUploads, !uploads.isEmpty else {
        // 没有上传文件
        response.completed(status: .badRequest)
        return
    }
    
    // 遍历文件数组
    for upload in uploads {
        // 获取文件名和临时文件路径
        let fileName = upload.fileName
        let tempFilePath = upload.tmpFileName
        
        // 可以根据需要对文件进行处理
        // 比如保存到服务器的特定位置
        let destinationPath = "/path/to/save/\(fileName)"
        do {
            try FileManager.default.moveItem(atPath: tempFilePath, toPath: destinationPath)
        } catch {
            // 处理文件保存错误
            response.completed(status: .internalServerError)
            return
        }
    }
    
    // 文件上传成功
    response.completed(status: .ok)
}

// 创建路由
let routes = [
    Route(method: .post, uri: "/upload", handler: uploadHandler)
]

// 创建服务器
let server = HTTPServer()
server.addRoutes(routes)

// 启动服务器
do {
    try server.start()
} catch {
    print("Server start error: \(error)")
}
