基于AFNetworking3.0封裝網(wǎng)絡(luò)請求功能，API面向業(yè)務(wù)層更友好，基礎(chǔ)功能包括GET、POST、下載、單文件上傳、多文件上傳、取消網(wǎng)絡(luò)請求。此外還拓展出了緩存功能，緩存分為內(nèi)存緩存和磁盤緩存。

取消所有網(wǎng)絡(luò)請求

+?(void)cancleAllRequest;

取消下載請求

+?(void)cancelRequestWithURL:(NSString?*)url;

獲取緩存大小

/**
?*??獲取緩存大小
?*
?*??@return?緩存大小
?*/
+?(unsigned?long?long)totalCacheSize;

清理緩存

/**
?*??清除所有緩存
?*/
+?(void)clearTotalCache;

自動清理緩存

????//每次網(wǎng)絡(luò)請求的時候，檢查此時磁盤中的緩存大小，如果超過閾值，則清理所有緩存
????//未來優(yōu)化點：1、這里到時會做進(jìn)一步優(yōu)化，到時會有兩種清理策略，一種基于時間維度，一種基于緩存大小,
????//??????????2、清理也不會清理全部，會采取LRU算法來淘汰在磁盤中價值最低的緩存
????if?([self?totalCacheSize]?>?CACHEMAXSIZE)?[self?clearTotalCache];

Usage Tip

1.?對于cache與否，到時大家針對自己的業(yè)務(wù)數(shù)據(jù)的特征來決定是否開啟cache,即時性或時效性的數(shù)據(jù)建議不開啟緩存，一般建議開啟，開啟緩存后會回調(diào)兩次，第一次獲取是緩存數(shù)據(jù)，第二次獲取的是最新的網(wǎng)絡(luò)數(shù)據(jù)；
2.?新版本多了一個刷新請求參數(shù)，設(shè)置它是為了解決重復(fù)請求的問題，舉個例子，當(dāng)我們在列表里面上拉獲取更多數(shù)據(jù)的時候，有時候因為網(wǎng)絡(luò)慢，還沒有回調(diào)響應(yīng)刷新出數(shù)據(jù)，這時候我們可能不斷去上拉列表，如果業(yè)務(wù)層不判斷，就會發(fā)起很多重復(fù)的請求。遇到重復(fù)請求，若參數(shù)設(shè)為YES，則會取消舊的請求，用新的請求，若設(shè)為NO，則忽略新請求，用舊請求。
3.?具體使用的時候，建議面向業(yè)務(wù)層再封裝一次Service層或者將網(wǎng)絡(luò)請求寫進(jìn)MVVM的viewModel中，向controller暴露只面向業(yè)務(wù)的參數(shù)。

Extension For Future

1.?為緩存添加相應(yīng)的緩存淘汰算法LRU；
2.?再封裝面向業(yè)務(wù)更友好的manager，管理業(yè)務(wù)層的API，使其方便在不同網(wǎng)絡(luò)環(huán)境下切換（測試環(huán)境與正式環(huán)境......）
