Swift中Firebase的post中的数据结构问题

import Foundation

// 定义数据结构
struct PostData: Codable {
    let title: String
    let content: String
}

// 创建要发送的数据
let postData = PostData(title: "Hello", content: "This is a post")

// 将数据转换为JSON格式
let jsonEncoder = JSONEncoder()
guard let jsonData = try? jsonEncoder.encode(postData) else {
    print("Failed to encode data")
    return
}

// 创建POST请求
let url = URL(string: "https://your-firebase-database-url/posts.json")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = jsonData

// 发送请求
let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
    if let error = error {
        print("Error: \(error)")
    } else if let data = data {
        let responseString = String(data: data, encoding: .utf8)
        print("Response: \(responseString ?? "")")
    }
}
task.resume()
