[iOS]封裝自己所需要的Networking

以前開始學(xué)習(xí)iOS的時候網(wǎng)絡(luò)請求都是直接用AFN，每一次請求都特別繁瑣，最近完善了一下自己寫的請求封裝，分享一下。

以下代碼為Swift版本，如果需要Object-c的可以去我的github(https://github.com/JakeZhucl/CLBaseObject-C)下載

下面是我心里想的封裝需求：
1.添加公共參數(shù)
2.緩存請求的結(jié)果
3.要可以處理tableview, scrollview,collectionview的停止刷新
4.可以加密
5.打印對應(yīng)的請求、參數(shù)、加密參數(shù)和結(jié)果

開始吧

1.既然需要處理公共參數(shù)，那就寫一個處理參數(shù)的方法

private class func addPostParameters( parameters : Dictionary<String, Any>?) -> Dictionary<String, Any>{
        
        var newParameters = Dictionary<String,Any>()
        /*這里的內(nèi)容都是公共參數(shù)，看需求添加
        newParameters["vid"] = Account.account().vid
        newParameters["user_id"] = Account.account().user_id
        newParameters["app_flag"] = APP_FLAG
        newParameters["device"] = "iOS"
         */
        //版本號
        newParameters["version"] = Bundle.main.infoDictionary!["CFBundleShortVersionString"] as! String
        //bundleId
        newParameters["bundleid"] = Bundle.main.object(forInfoDictionaryKey: "CFBundleIdentifier")
        //如果沒有參數(shù)傳入就直接返回公共參數(shù)，如果有參數(shù)傳入就將參數(shù)字典的東西通過遍歷加到公共參數(shù)返回作為最后的請求參數(shù)
        if parameters == nil {
            return newParameters
        }else{
            for (key,value) in parameters!{
                newParameters[key] = value
            }
            return newParameters
        }
    }

2.緩存我采用的yycache這個第三方庫（主要是這個用習(xí)慣了

let clCache = YYCache(name: "product_name")
//講請求的參數(shù)字典的key變成有序的，為了下一步存儲的時候變成string不會每次都不一樣
let parametersKeys = addParameters.keys.sorted { (num1 , num2) -> Bool in
    return num1 < num2
}

var cacheString = ""
for key in parametersKeys {
    if key != "lat" && key != "lng" {
    cacheString += "\(key)\(String(describing:addParameters[key]))"
        }
}
//這個cacheurl就是請求路徑和請求參數(shù)要放進(jìn)cache的key
let cacheURL =  "\(url)\(cacheString)"

Alamofire.request(url, method: .post, parameters: parameters, encoding: URLEncoding.default, headers: nil).response { (response) in
            SVProgressHUD.setDefaultMaskType(.none)
            if (response.error == nil ) {
                if response.data != nil {
                    if isCache {
                        //請求結(jié)束的時候就可以將請求結(jié)果當(dāng)作value，剛剛的url當(dāng)作key存到本地了
                        clCache?.setObject(response.data! as NSData, forKey: cacheURL)
                    }
                }
            }
        }

3.添加自動停止刷新的方法，這個真的非常有用，添加后，在寫tableview、scorllview、collection就完全不用考慮是否會出現(xiàn)忘記寫停止刷新的方法了

//我這里是將請求已經(jīng)全部轉(zhuǎn)換成model了
private class func endRefresh(model : CLNetWorkModel,
                                  scrollview : UIScrollView ,
                                  isCache : Bool){
        if !isCache {
            //后端返回isnull來控制是否最后一頁，所以這邊由isnull控制是否endRefreshing
            if model.isnull == "0" {
                if scrollview.mj_footer != nil {
                    scrollview.mj_footer.endRefreshing()
                }
            }else{
                if scrollview.mj_footer != nil {
                    scrollview.mj_footer.endRefreshingWithNoMoreData()
                }
            }
            
            if scrollview.mj_header != nil {
                scrollview.mj_header.endRefreshing()
            }
        }
    }

4.加密 我公司根據(jù)項(xiàng)目采用des還是aes（不知道為什么，可能是哪個代碼好復(fù)制用哪個吧

//這個isDes是一個屬性 用來控制萬一項(xiàng)目不采用加密的方式就不用去除代碼了（如果你的需求是項(xiàng)目某一個請求不需要加密，那你就再通過函數(shù)的參數(shù)來控制

if isDes {
    parameters["data"] = CLDes.encryptUse(addParameters.CLDictionaryToJsonString())
    print(parameters.CLDictionaryToJsonString())
}else{
    parameters = addParameters
}

好啦。我把全部代碼放上去
