如何在swift中使用嵌套字典发送POST请求

import Foundation

let parameters: [String: Any] = [
    "name": "John Doe",
    "age": 25,
    "address": [
        "street": "123 Main St",
        "city": "New York",
        "state": "NY"
    ]
]

guard let jsonData = try? JSONSerialization.data(withJSONObject: parameters, options: []) else {
    print("Failed to convert parameters to JSON data")
    return
}

guard let url = URL(string: "https://example.com/api") else {
    print("Invalid URL")
    return
}

var request = URLRequest(url: url)
request.httpMethod = "POST"

request.httpBody = jsonData

request.setValue("application/json", forHTTPHeaderField: "Content-Type")

let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
    if let error = error {
        print("Error: \(error)")
        return
    }
    
    guard let data = data else {
        print("No data received")
        return
    }
    
    // 处理响应数据
    if let responseString = String(data: data, encoding: .utf8) {
        print("Response: \(responseString)")
    }
}

task.resume()
