Alamofire的簡(jiǎn)單二次封裝。這里數(shù)據(jù)解析使用swiftyJSON

import SwiftyJSON
import Alamofire

enum RequestType {
    case Get
    
    case Post
    
    case Put
    
    case Delete
}

typealias complete = (Bool?,AnyObject?)->Void


class JCNetTool {
    static let manage:SessionManager = {
        var defHeards = Alamofire.SessionManager.default.session.configuration.httpAdditionalHeaders ?? [:]
        let defConf = URLSessionConfiguration.default
        
        defConf.timeoutIntervalForRequest = 10
        defConf.httpAdditionalHeaders = defHeards
        
        return Alamofire.SessionManager(configuration: defConf, delegate: SessionDelegate(), serverTrustPolicyManager: nil)
    }()
}

extension JCNetTool {
    
    static func requestData(requestType : RequestType,URLString : String,parameters : [String:Any]? = nil , successed : @escaping complete,failured:@escaping complete){
        
        
        //獲取請(qǐng)求類型
        var method : HTTPMethod?
        
        switch requestType {
        case .Get:
            method = HTTPMethod.get
        case .Post:
            method = HTTPMethod.post
        case .Put:
            method = HTTPMethod.put
        case .Delete:
            method = HTTPMethod.delete
            
        }
        //當(dāng)前時(shí)間的時(shí)間戳
        let timeInterval:TimeInterval = Date().timeIntervalSince1970
        let timeStamp = Int(timeInterval)
        let headers:HTTPHeaders = [
            "AccessCode"     : "AccessCode",
            "timeStamp"       : "\(timeStamp)",
            "Signature"         : "SHA1算法簽名"
        ]
        //發(fā)送網(wǎng)絡(luò)請(qǐng)求
        Alamofire.request(URLString, method: method!, parameters: parameters, encoding: JSONEncoding.default, headers: headers).responseJSON { (response) in
            //獲取返回結(jié)果
            
            switch response.result {
            case .success:
                let json = JSON(response.result.value as Any)
                if json["Code"] == "404"{
                    print("連接失敗")
   
                }else{
                    successed(true, response.result.value as AnyObject)
                    
                }
            case .failure:
                failured(false, "連接服務(wù)器失敗" as AnyObject)
            }
            
        }
    }
 
}

如果headers沒(méi)有特殊設(shè)置，可以在請(qǐng)求的地方設(shè)置為nil，在網(wǎng)絡(luò)訪問(wèn)是只需要傳入請(qǐng)求類型、URL地址、json參數(shù)就能很方便的使用。
