使用NSURLSession将Android post请求转换为iOS swift

// 创建URL对象
let url = URL(string: "http://example.com/api/endpoint")!

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

// 设置请求头
request.setValue("application/json", forHTTPHeaderField: "Content-Type")

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

// 创建NSURLSession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("请求失败：\(error)")
        return
    }

    // 处理响应数据
    if let data = data {
        let responseString = String(data: data, encoding: .utf8)
        print("响应数据：\(responseString ?? "")")
    }
}

// 启动任务
task.resume()
