Examples with Dispatcher okhttp3.Dispatcher used on opensource projects

Example 61 with Dispatcher

use of okhttp3.Dispatcher in project BestPracticeApp by pop1234o.

the class MainActivity method requestOkHttpGet.

/**
 * ==============================
 * 先用Builder模式来构建Request对象，然后将Request封装成一个Call（RealCall）对象
 *  调用RealCall.execute。里面使用OkHttpClient.Dispatcher.execute(call)
 *  里面将call加入Dispatcher中ArrayDeque中，然后再 RealCall.getResponseWithInterceptorChain()
 *  中创建各种拦截器，（
 *  BridgeInterceptor 添加请求头，比如User-Agent，Connection，Host
 *  CacheInterceptor请求头缓存设置，
 *  ConnectInterceptor获取http连接，判断是1.0还是1.1，
 *              获取到HttpCodec对象，真正建立起了Socket连接
 *  CallServerInterceptor 将请求行，请求头写入Socket,然后发送到服务端，接收Socket响应
 *  这里用的是BufferedSource 是okio，NIO，然后获取到http响应，解析响应行，响应头，响应体
 *  用ResponseBuilder来创建一个Response，然后返回
 *  ）
 *  以上是一个同步的过程，异步的过程类似，就是创建一个AsyncCall然后用线程池执行
 *  返回Response后调用回调方法回调都是在子线程。
 *  =================================
 *  他的巧妙的结构在于 ,链式的调用结构
 *  Response r = chain.proceed(request)；
 *
 *  Interceptor=>
 *  Response intercept(Chain chain){
 *      //处理Request
 *     Response r = chain.proceed(chain.request());
 *     //处理Response
 *     return r;
 *  }
 *
 *  Chain=>中方法
 *  Response proceed(Request request){
 *      //这里主要遍历取出拦截器
 *     Response r = interceptors.get(index++).intercept(new Chain());
 *     return r;
 *  }
 *
 * ==============================
 * 使用builder模式创建Request,OkHttpClient
 * 使用工厂模式创建 EventListener
 * 策略模式，设置拦截器
