如何在swift中将嵌套的json作为请求参数发送？

let nestedJSON: [String: Any] = [
    "name": "John Doe",
    "age": 30,
    "address": [
        "street": "123 Main St",
        "city": "New York",
        "country": "USA"
    ]
]

guard let jsonData = try? JSONSerialization.data(withJSONObject: nestedJSON, options: []) else {
    // 处理转换失败的情况
    return
}

guard let url = URL(string: "https://example.com/api") else {
    // 处理URL创建失败的情况
    return
}

var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.httpBody = jsonData

let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
    if let error = error {
        // 处理请求错误的情况
        print("请求错误：\(error)")
        return
    }
    
    if let data = data {
        // 处理响应数据
        let responseJSON = try? JSONSerialization.jsonObject(with: data, options: [])
        print("响应数据：\(responseJSON ?? "")")
    }
}

task.resume()
