首先用橋接或pods將AFNetworking匯入專案,在這不再贅述,然後建立一個單例NetWorkTools.swift

繼承:AFHTTPSessionManager

import UIKit
import AFNetworking

//列舉定義請求方式
enum HTTPRequestType {
    case GET
    case POST
}

class NetworkManager: AFHTTPSessionManager {

    //單例
    static let shared = NetworkManager()

    /// 封裝GET和POST 請求
 

    ///
    /// - Parameters:
    ///   - requestType: 請求方式
    ///   - urlString: urlString
    ///   - parameters: 字典引數
    ///   - completion: 回撥
    func request(requestType: HTTPRequestType, urlString: String, parameters: [String: AnyObject]?, completion: @escaping (AnyObject?) -> ()) {

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

        //失敗回撥
        let failure = { (task: URLSessionDataTask?, error: Error) -> () in
            print("網路請求錯誤 \(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)
        }
    }
}

呼叫的地方

NetworkManager.shared.request(requestType: .GET, urlString: "https:www.baidu.com", parameters: ["userName": "zhangsan" as AnyObject]) { (json) in
    print(json)
}
