Alamofire 版本 4.4.0

PS： 語(yǔ)法有點(diǎn)改變，Method改變成了HTTPMethod。。。

封裝這個(gè)類(lèi)的主要目的是以后換框架不用改那么多地方，只要改這個(gè)工具類(lèi)就好了。

import UIKit
import Alamofire
// 枚舉請(qǐng)求方式
enum MethodType {
case GET
case POST
}

// 搞個(gè)工具類(lèi)
class NetworkTools {
// 1.搞個(gè)全局函數(shù) 接收外面的值 用閉包回傳
static func requstDate(URLString: String, type: MethodType, parameters: [String : NSString]? = nil, finishedCallblack : @escaping (_ result : AnyObject)->()){
    // 2.判斷類(lèi)型
    let method = type == .GET ? HTTPMethod.get : HTTPMethod.post
    // 3.拿到傳過(guò)來(lái)的參數(shù)處理
    Alamofire.request(URLString, method: method, parameters: parameters).responseJSON { (response) in
        // 4.先判斷閉包的結(jié)果是否為空
        guard let result = response.result.value else {
            // 為空就打印錯(cuò)誤后返回
            print(response.result.error)
            return
        }
        // 有值就給閉包傳出去
        finishedCallblack(result as AnyObject)
        }   
    }
}

封裝以后使用直接面向工具類(lèi)了

import UIKit
import Alamofire

class ViewController: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()
    let getStr = "http://httpbin.org/get"
    let postStr = "http://httpbin.org/post"
    
    // 面向Alamofire
    Alamofire.request(getStr, method: .get).responseJSON { (response) in
        print(response.result.value)
    }
    
    Alamofire.request(postStr, method: .post, parameters: ["name" : "jack"]).responseJSON { (response) in
        print(response)
    }
    
    // 面向NetworkTools工具類(lèi)
    NetworkTools.requstDate(URLString: getStr, type: .GET) { (response) in
        print(response)
    }
    
    NetworkTools.requstDate(URLString: postStr, type: .POST, parameters: ["name" : "jack"]) { (response) in
        print(response)
    }
    
    
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
    }
}
