有没有办法在Alamofire中以对象而不是参数的形式发送数据？

import Alamofire

struct User {
    var name: String
    var age: Int
    var email: String
}

let user = User(name: "John Doe", age: 25, email: "johndoe@example.com")

do {
    let jsonEncoder = JSONEncoder()
    let jsonData = try jsonEncoder.encode(user)
    let jsonString = String(data: jsonData, encoding: .utf8)!
    
    let parameters = ["user": jsonString]
    
    Alamofire.request("https://example.com/api", method: .post, parameters: parameters, encoding: JSONEncoding.default)
        .responseJSON { response in
            // 处理服务器响应
        }
} catch {
    print("Error encoding user object: \(error)")
}
