网络请求:Alamfire+数据模型

首先在Podfiled中导入三个框架

 pod 'Alamofire'
 pod 'SwiftyJSON'
 pod 'HandyJSON'

创建名为NetworkTool的swift文件，进行网络请求

import UIKit
import Alamofire
import SwiftyJSON
//import SwiftyJSON

protocol NetworkToolProtocol {
  //-------------------我的 Mine ------------------
  //我的界面Cell的数据
  static func loadMyCellData(completionHandler:@escaping (_ sections:[[MyCellModel]])->())
  //我的关注的数据

extension NetworkToolProtocol{
  //我的界面cell的数据请求
  static func loadMyCellData(completionHandler:@escaping (_ sections:[[MyCellModel]])->()){
      let url = BASE_URL + "/user/tab/tabs/?"
      let params = ["device_id":device_id]
      Alamofire.request(url,parameters:params).responseJSON { (response) in
          //判断网络请求是否成功
          guard response.result.isSuccess else{
              //网络错误的提示信息
              return
          }
          if let value = response.result.value{
              //JSON  SwiftyJSON语句
              let json = JSON(value)
              guard json["message"] == "success" else{return}
              if let data = json["data"].dictionary{
                  print(data)
                  if let sections = data["sections"]?.array{
                      var sectionArray = [[MyCellModel]]()
                      for item in sections{
                          var rows = [MyCellModel]()
                          for row in item.arrayObject!{
                              let myCellModel = MyCellModel.deserialize(from: row as? NSDictionary)
                              rows.append(myCellModel!)
                          }
                          sectionArray.append(rows)
                      }
                      completionHandler(sectionArray)
                  }
          }
      }
  }
  }
}
struct NetworkTool:NetworkToolProtocol {}

获取数据JSON图：

{
    "data": {
        "sections": [
            [
                {
                    "text": "我的钱包",
                    "grey_text": "全民抽奖7月好礼",
                    "url": "sslocal://webview?url=https%3a%2f%2fis.snssdk.com%2ffeoffline%2fwallet_portal%2findex.html&title=%E6%88%91%E7%9A%84%E9%92%B1%E5%8C%85&hide_more=1&hide_bar=1&bounce_disable=1&hide_status_bar=1&back_button_color=white&status_bar_color=white&background_colorkey=3&should_append_common_param=1&disable_web_progressView=1&use_offline=1&show_load_anim=0",
                    "key": "mall",
                    "icons": {
                        "day": {
                            "height": 24,
                            "radius": 0,
                            "uri": "",
                            "url_list": [
                                {
                                    "url": "http://p3.pstatp.com/origin/1e0660002e8c1d26332ce"
                                }
                            ],
                            "width": 24
                        },
                        "night": {
                            "height": 24,
                            "radius": 0,
                            "uri": "",
                            "url_list": [
                                {
                                    "url": "http://p3.pstatp.com/origin/1e0660002e8c1d26332ce"
                                }
                            ],
                            "width": 24
                        }
                    },
                    "tip_new": 0,
                    "tip_text": ""
                },
                {...}
            ],
            [...],
            [...]
        ]
    },
    "message": "success"
}

创建一个名为MyCellModel的数据模型文件，来对应获取的数据。

import HandyJSON
struct MyCellModel:HandyJSON {
    var grey_text:String = ""
    var text:String = ""
    var url:String = ""
    var key:String = ""
    var tip_new:Int = 0
    }
}

最后在需要获取数据的地方调用此代码

  NetworkTool.loadMyCellData(completionHandler: )
