获取Swift HTTP POST并解码JSON响应

import Foundation

// 定义请求的URL
let url = URL(string: "https://example.com/api/endpoint")!

// 创建请求对象
var request = URLRequest(url: url)
request.httpMethod = "POST"

// 设置请求体数据
let parameters = ["key1": "value1", "key2": "value2"]
request.httpBody = try? JSONSerialization.data(withJSONObject: parameters)

// 创建URLSession对象
let session = URLSession.shared

// 发送请求
let task = session.dataTask(with: request) { (data, response, error) in
    if let error = error {
        print("请求出错：\(error)")
        return
    }
    
    // 解析响应数据
    if let data = data {
        do {
            let json = try JSONSerialization.jsonObject(with: data, options: [])
            if let dictionary = json as? [String: Any] {
                // 在这里可以处理解析后的JSON数据
                print(dictionary)
            }
        } catch {
            print("解析JSON出错：\(error)")
        }
    }
}

// 启动请求任务
task.resume()
