本文介绍了一个用Swift实现的网络请求封装类，支持GET和POST请求，并通过AFNetworking库进行网络通信。该封装类使用单例模式，简化了JSON数据的序列化与反序列化过程。

创建 一个  NewworkingTools.swift  文件
import Foundation
import AFNetworking

//枚举定义请求方式
enum HTTPRequestType {
    case GET
    case POST
}

class NetworkManager: AFHTTPSessionManager {

    //单例
    static let shared : NetworkManager = {
        let tools = NetworkManager()
        tools.requestSerializer = AFJSONRequestSerializer()
        tools.responseSerializer = AFJSONResponseSerializer()
        tools.requestSerializer.setValue("application/json,text/html", forHTTPHeaderField: "Accept")
        tools.requestSerializer.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
        return tools
    }()

    /// 封装GET和POST 请求
    ///
    /// - Parameters:
    ///   - requestType: 请求方式
    ///   - urlString: urlString
    ///   - parameters: 字典参数
    ///   - completion: 回调
    func request(requestType: HTTPRequestType, urlString: String, parameters: [String: AnyObject]?, completion: @escaping (AnyObject?) -> ()) {

        //成功回调
        let success = { (task: URLSessionDataTask, json: Any)->() in
            completion(json as AnyObject?)
        }

        //失败回调
        let failure = { (task: URLSessionDataTask?, error: Error) -> () in
            print("网络请求错误 \(error)")
            completion(nil)
        }

        if requestType == .GET {
            get(urlString, parameters: parameters, progress: nil, success: success, failure: failure)
        } else {
            post(urlString, parameters: parameters, progress: nil, success: success, failure: failure)
        }
    }
}

使用

   NetworkManager.shared.request(requestType: .GET, urlString: "https://******/login", parameters: ["account": "111111" as AnyObject, "password" : "111111" as AnyObject]) { (json) in
            print(json as Any)
        }
