ios - 代码优化在 ios Swift 中不起作用？

Question

我正在使用 Swift 和 alamofire。

如何进行代码优化？这是我对不同 api 的帖子和请求:

func    getPDataFromURL(_ onCompletion:@escaping (Dictionary<String,    Any>)-> Void)
      {
      let token  =  UserDefaults.standard.string(forKey: "UserLoginToken")
      let Usertype  =  UserDefaults.standard.string(forKey: "Usertype")
      let Userbranchid  =  UserDefaults.standard.string(forKey: "Userbranchid")

      let UrlStraing = FETCH_Parent_Profile_URL 

      print(UrlStraing)

            let url = URL(string: UrlStraing)!
      var urlRequest = URLRequest(url:url)
      urlRequest.httpMethod = "GET"
      urlRequest.addValue("application/json", forHTTPHeaderField: "Content-Type")
      urlRequest.addValue("application/json", forHTTPHeaderField: "Accept")
          let  userToken = "Token token=" + token! as String
          urlRequest.addValue(userToken, forHTTPHeaderField: "Authorization")
      Alamofire.request(urlRequest).responseJSON { (response:DataResponse<Any>) in
          switch(response.result) {
          case .success(_):
              if response.result.value != nil{
                  print(response.result.value!)
                  onCompletion(response.result.value! as! Dictionary<String, Any>)
              }
              break

          case .failure(_):
              print(response.result.error!)
              onCompletion(response.result.error as! Dictionary<String, Any>)
              break
          }
      }
}

这是我对另一个 api 的第二个帖子请求:

func getSDataFromURL(_ onCompletion:@escaping  (Dictionary<String, Any>)-> Void)    {
      let token  =  UserDefaults.standard.string(forKey: "UserLoginToken")
      let Usertype  =  UserDefaults.standard.string(forKey: "Usertype")
      let Userbranchid  =  UserDefaults.standard.string(forKey: "Userbranchid")

      let UrlStraing = FETCH_School_Info_URL + "branch_id=" + Userbranchid! + "&student_id=86&user_type=" + Usertype!

      print(UrlStraing)

      let url = URL(string: UrlStraing)!
      var urlRequest = URLRequest(url:url)
      urlRequest.httpMethod = "GET"
      urlRequest.addValue("application/json", forHTTPHeaderField: "Content-Type")
      urlRequest.addValue("application/json", forHTTPHeaderField: "Accept")
      let  userToken = "Token token=" + token! as String
      urlRequest.addValue(userToken, forHTTPHeaderField: "Authorization")
      Alamofire.request(urlRequest).responseJSON { (response:DataResponse<Any>) in
          switch(response.result) {
          case .success(_):
              if response.result.value != nil{
                  print(response.result.value!)
                  onCompletion(response.result.value! as! Dictionary<String, Any>)
              }
              break

          case .failure(_):
              print(response.result.error!)
              onCompletion(response.result.error as! Dictionary<String, Any>)
              break
          }
      }
}

然后像这样在 viewcontroller 中调用函数:

func SetUpSchoolUIProfiledata()    {
      Common.sharedInstance.StartActivity(view: self.view)
      DispatchQueue.main.async {
      APIManager.sharedInstance.getSchoolProfileDataFromURL(){(userJson)->
Void in

          self.stop()
          let swiftyJsonVar = JSON(userJson)
          print("userJson userJson userJson userJson",userJson)

          print("swiftyJsonVar",swiftyJsonVar)

          let message = swiftyJsonVar["message"].rawString()
          let info = swiftyJsonVar["info"].rawString()!

          let jsonData = info.data(using: .utf8)!
          let dictionary = try? JSONSerialization.jsonObject(with: jsonData, options: [])  as! Dictionary<String, Any>

          self.schoolName_lbl.text = dictionary?["name"] as? String
          self.add1_lbl.text = dictionary?["add_line1"] as? String
          print("imgURLstring  is ",self.imgURLstring)
          self.SetUpProfileImage()
      }
      }
}  

如何创建单一功能的多个 post 和 get 请求？

Answer 1

你可以像这样创建单例类当你想调用网络服务时，使用这个方法

class DataProvider: NSObject {

    class var sharedInstance:DataProvider {
        struct Singleton {
            static let instance = DataProvider()
        }
        return Singleton.instance
    }

    let baseUrl:String = "http://192.168.1.25:3004/api3/v3/"



     func putData( parameter:[String:String], url:String, _ successBlock:@escaping ( _ response: JSON )->Void , errorBlock: @escaping (_ error: NSError) -> Void ){

            let path =  baseUrl + url
            print(path)
            print(parameter)

            let headers = ["authorization": AppData().token]

            Alamofire.request(path, method: .put, parameters: parameter, encoding: JSONEncoding.default, headers: headers).responseJSON { response in

                switch response.result {
                case .success:
                    if let value = response.result.value {
                        let json = JSON(value)
                        successBlock(json)
                    }
                case .failure(let error):
                    errorBlock(error as NSError)
                }
            }
    }

这样调用

DataProvider.sharedInstance.putData(parameter: parameter, url: "users/account/update", { (response) in
            print(response)

            if response["status"].stringValue == "200" {
                Utility.showMessageDialog(onController: self, withTitle: "", withMessage: response["message"].stringValue)
            }


        }) { (error) in
            print(error)
        }
