熟练使用Alamofire请求数据

如果项目稍大一些,就尽量使用路由Route 组织形成url请求,避免很多次重复代码, 看起来也直观.

import UIKit
import Alamofire
struct KF {
enum Router: URLRequestConvertible{
    static let baseUrlString = "http://www.aaazb.com"

    case login([String: AnyObject])

    var  method : Alamofire.Method{
        switch self{
        case .login:
            return .POST
        }
    }

    var path: String{
        switch self{
        case .login:
            return "/login"
        }
    }

    var URLRequest: NSURLRequest{
        let URL = NSURL(string: Router.baseUrlString)
        let mutableURLRequest = NSMutableURLRequest(URL:URL!.URLByAppendingPathComponent(path))
            mutableURLRequest.HTTPMethod = method.rawValue
        mutableURLRequest.setValue("secondzilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36 (KHTML, like Gecko) ipad/40.0.2125.122 Safari/537.36", forHTTPHeaderField: "User-Agent")
        mutableURLRequest.setValue("XMLHttpRequest", forHTTPHeaderField: "X-Request-With")
        mutableURLRequest.setValue("application/json", forHTTPHeaderField: "Accept")
        switch self{
        case .login(let parameters):
             return Alamofire.ParameterEncoding.URL.encode(mutableURLRequest, parameters: parameters).0
        }
    }
}
}

用到请求的时候:

Alamofire.request(KindFoo.Router.login(["user_name":"shan","user_pwd":"shan","uuid":"567-F8E9EBC8-6286-420A-B9D8-9FABC50B30CD"]))
            .responseJSON { (_, _, JSON, _) in
            println(JSON!.valueForKey("m"))
            //println(JSON)
        }

Alamofire是基于NSURLRequest封装的,所以Cookie会自动保存,就和浏览器请求是一个效果,而且网站Set_cookie多久,本地的Cookie 就多久,每次请求的时候都会自动带上cookie,直到过期.

如何查看cookie:

var url = NSURL(string: "http://www.aaazb.com")
var cookieJar = NSHTTPCookieStorage.sharedHTTPCookieStorage().cookiesForURL(url!)

如何清空Cookie:

 var url = NSURL(string: "http://www.aaazb.com")
 var cookieJar:NSArray = NSHTTPCookieStorage.sharedHTTPCookieStorage().cookiesForURL(url!)!
 //print(cookieJar.count)
 for i in cookieJar {
    NSHTTPCookieStorage.sharedHTTPCookieStorage().deleteCookie(i as NSHTTPCookie)
 }

设置Cookie:
