Swift里封装AFNetworking

//
//  NetWorkTools.swift


import UIKit
import AFNetworking

class NetWorkTools: AFHTTPSessionManager {

    /// 静态属性
    static let tools:NetWorkTools = {
        // 注意:baseURL 一定要以"/"结尾
        let url = NSURL(string: "https://api.weibo.com/")
        let t = NetWorkTools(baseURL: url)

        // 设置AFN能够接受的数据类型
        t.responseSerializer.acceptableContentTypes = (NSSet(objects: "application/json", "text/json", "text/javascript", "text/plain") as! Set<String>)        
        return t
    }()

    /**
     获取单列的方法
     */
    class func shareNetWorkTools() -> NetWorkTools {
        return tools;
    }
}

如何使用？
1. POST请求

// 1.定义路径
        let path = "oauth2/access_token"

        // 2.封装参数
        let params = ["client_id":AppKey,"client_secret":AppSecret,"grant_type":"authorization_code","code":code,"redirect_uri":redirect_uri]

        // 3.发送POST请求
        NetWorkTools.shareNetWorkTools().POST(path, parameters: params, success: { (_, JSON) in

            // 打印JSON数据
            print(JSON)

        }) { (_, error) in

                print(error)
        }
