connect（）和disconnect（）在哪里实现？ [英] Where is connect() and disconnect() implemented?

问题描述

在 java.net.URLConnetion.java 和 java.net.HttpURLConnection.java 中，只有摘要 connect（）和 disconnect（）的方法。

In java.net.URLConnetion.java and java.net.HttpURLConnection.java, there are only abstract methods for connect() and disconnect(), respectively.

@ abstract public void connect() throws IOException;
@ public abstract void disconnect();

有谁知道实现它们的实际代码在哪里？

Does anyone know where is the actual codes that implement them?

我想知道 HttpURLConnection 如何与TCP堆栈通信。

I want to know how the HttpURLConnection communicate with TCP stack.

此外，还有更抽象的函数，例如 usingProxy（）。它们的代码在哪里？

Besides, there are more abstract functions, such as usingProxy(). Where is the code for them?

推荐答案

java.net.HttpURLConnection.java 有一个已实现该方法的实现 HttpsURLConnectionImpl 。它使用委托 DelegateHttpsURLConnection 扩展 AbstractDelegateHttpsURLConnection 已实现 connect（）方法

java.net.HttpURLConnection.java has an implementation HttpsURLConnectionImpl that has implemented the method. It uses a delegate DelegateHttpsURLConnection that extends AbstractDelegateHttpsURLConnection which has implemented the connect() method
