ios開發之--swift下AFNetworking的使用

1，首先使用cocoapods匯入，如果有不會的同學，可以去看我寫的關於cocopods使用的那篇部落格

2，直接上代碼：

import UIKitimport AFNetworking//枚舉定義要求方法enum HTTPRequestType{    case GET    case POST}class AFNetTools: AFHTTPSessionManager {        //單例類    static let shareInstance : AFNetTools = {        let toolInstance = AFNetTools()        toolInstance.responseSerializer.acceptableContentTypes?.insert("text/html")        return toolInstance    }()        /// 封裝GET和POST 請求    ///    /// - Parameters:    ///   - requestType: 請求方式    ///   - urlString: urlString    ///   - parameters: 字典參數    ///   - completion: 回調    func request(requestType: HTTPRequestType, urlString: String, parameters: [String: AnyObject]?, completion: @escaping (AnyObject?) -> ()) {                //成功回調        let success = { (task: URLSessionDataTask, json: Any)->() in            completion(json as AnyObject?)        }                //失敗回調        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)        }    }        // 將成功和失敗的回調分別寫在兩個逃逸閉包中    func request(requestType : HTTPRequestType, url : String, parameters : [String : Any], succeed : @escaping([String : Any]?) -> (), failure : @escaping(Error?) -> ()) {                // 成功閉包        let successBlock = { (task: URLSessionDataTask, responseObj: Any?) in            succeed(responseObj as? [String : Any])        }                // 失敗的閉包        let failureBlock = { (task: URLSessionDataTask?, error: Error) in            failure(error)        }                // Get 請求        if requestType == .GET {            get(url, parameters: parameters, progress: nil, success: successBlock, failure: failureBlock)        }                // Post 請求        if requestType == .POST {            post(url, parameters: parameters, progress: nil, success: successBlock, failure: failureBlock)        }    }    }

以上就是二次封裝的請求類

3，調用：

@IBAction func startRequest(_ sender: Any) {        let paramerts = [            "opt_type": 1,            "size" : 50,            "offset" : 50        ]                AFNetTools.shareInstance.request(requestType: .GET, url: "http://apiv2.yangkeduo.com/operation/15/groups", parameters: paramerts, succeed: { (response) in            guard let dicArray = response?["goods_list"] as? [[String: Any]] else {                return            }            print(dicArray)                    }) { (error) in            guard let error = error else {                return            }            print(error)        }            }
