总结：

1. 原始的`Base`，有`protocol`

满足`protocol`的类，用`Base+something`来定制他的扩展

2. 框架一定要有`嵌入`的手段，像`JSON转模型`的嵌入解析方法、YTK的各种`filter` + `jsonValidator`、CTNetwork的 `interceptor` + `validator`

3. success，failure的回调

相同： 

<1> YTK - jsonValidator == CT - CTAPIManagerValidatorProtocol - 这里`CT`支持`调用参数`和`返回数据`验证，而且采用了`protocol`的嵌入方式

不同：

<1> URL = base+detail+params

YTK - (通过`继承`的方式，由每个子类自己管理`URL`(base+detail+params) + YTKNetworkConfig) + YTKUrlFilterProtocol

`NetworkEngine` - 用`URLConfiguration`统一管理 + 分类中parameters字典

`CT` - CTService(base+extraParmas) + (CTAPIManagerParamSourceProtocol + reformParams继承)

<2> Cache

`YTK` - YTKRequest (fileManager+NSSecureCoding) - cacheTime继承实现

`CT` - CacheComponents (NSCache) - cacheTime (单例CTNetworkingConfigurationManager)

<3> 做网络请求

`YTK`和`CT`有`Base`，分业务继承，每个模块有自己的网络请求。

`NetworkEngine`�用分类，同一块业务用一个分类。

<4> request && response

`CT` - CTURLResponse

1. NetworkEngine

2. YTKNetwork

<1> YTKBaseRequest

i. RequestMethod + Request / ResponseSerializerType + Priority

ii. CompletionBlockCallback + YTKRequestDelegate + YTKRequestAccessory

iii. Request & Response + SubclassOverride

iv. - start - stop --> YTKNetworkAgent

<2> YTKBatchRequest + YTKBatchRequestAgent

i. YTKBatchRequestDelegate

ii. 对单一`request`的集合封装，各种成功失败回调

iii. 控制`BatchRequest`存储的单例

<3> YTKChainRequest + YTKChainRequestAgent

i. YTKChainRequestDelegate

ii. 对单一`BaseRequest`的集合封装，各种成功失败回调 - startNextRequest

iii. 控制`ChainRequest`存储的单例

<4> YTKNetworkAgent  --  AFHTTPSessionManager

i. -buildRequestUrl  --  // `requestUrl` + *`urlFilters` + `baseUrl` + *`useCDN`

ii. -requestSerializerForRequest  --  // (request序列化`Type` + timeout + Cellular + user&pass + HTTPHeaderField) -> requestSerializer

iii. -sessionTaskForRequest  --  // (`method` + `URL` + `params` + `formData` + requestSerializer) -> NSURLSessionTask

iv. -addRequest  --  // `requestTask` + `sessionTaskForRequest` + `requestPriority`

v. -validateResult  --  // `responseJSONObject` + `jsonValidator`

vi. -handleRequestResult  --  // `responseObject` + `responseData & responseString` + (responseSerializerType -> responseObject) + "DidSucceed + DidFail"

vii. -requestDidSucceedWithRequest  --  //各种`callback`

viii. -requestDidFailWithRequest  --  // `writeToURL: resumeData` + `responseObject返回URL，从URL拿数据`

vv. -downloadTaskWithDownloadPath  --  // `fileExists, isDirectory` + `ResumeData OR重新请求`

<5> YTKNetworkConfig  -  UrlFilter / CacheDirPathFilterProtocol

(AFSecurityPolicy + NSURLSessionConfiguration)

<6> YTKNetworkPrivate  -  (YTKNetworkUtils + 分类提供基础属性和方法)

<7> YTKRequest : YTKBaseRequest

Cache相关 - 读/写，directory/path/cacheFileName

response对象

3. RTNetworking  —  创建 - 实现 - 初始化配置

Intro

<1> (Interceptor(内、外) + paramSource + validator (`调用参数`和`返回数据`)) ==> 对应的`protocol`

<2> Reformer — 转换`api`返回的数据

<3> CTAPIBaseManager(继承) - reformParams (继承实现参数)

<4> Service(继承) + ServiceFactory

`Service` - BaseUrl+Version+Key

`ServiceFactory`通过字典配置`CTService <CTServiceProtocol>`子类

<5> Cache

---

<1> CTNetworkingConfigurationManager  --  cache + timeout + ...

<2> CTApiProxy  --  `AFHTTPSessionManager`实例，生成`GET/POST/PUT/DEL`请求，做网络请求，回调`success/failure`

<3> CTAPIBaseManager  --  依赖`CTApiProxy`做网络请求

i. delegate 

CTAPIManagerCallBackDelegate / CTAPIManagerDataReformer / CTAPIManagerValidator

CTAPIManagerParamSource / CTAPIManagerProtocol / CTAPIManagerInterceptor

ii. -fetchDataWithReformer  --  用外部提供`reformer`来无侵入的处理`fetchedRawData`

iii. -loadData  --  用外部提供`paramSource`来无侵入的提供`params`

iv. -loadDataWithParams --> requestId

-reformParams - 继承方法，返回`params`

-shouldCallAPIWithParams - AOP入`interceptor`

-manager:isCorrectWithParamsData -  AOP入`validator`

// 本地`userdefaults`,构建`CTURLResponse` + cache构建`CTURLResponse`

// `CTApiProxy`网络请求 - `requestType` -> CTApiProxy

v. -successedOnCallingAPI

// `NSUserDefaults`缓存`responseData`

// `fetchedRawData` + // validator + // cache - responseData

// AOP入`interceptor` + // callback - delegate

vi. -failedOnCallingAPI

// CTService/Factory + // service.child - `callback` + // fetchedRawData

// AOP入`interceptor` + (callback - delegate)

vii. method for interceptor X 6

<5> CTURLResponse  --  封装`request / response / error Stuff`

<6> CTRequestGenerator  --  AFHTTPRequestSerializer

i. `CTService` -> `urlString`

ii. AFHTTPRequestSerializer  --> `URLRequest`

iii. `service.child`提供`extraParams`

iv. `HTTPBody`

v. `service.child`提供`HTTPHeaderField`
