插座转换为字符串，反之亦然 [英] Convert Socket to String and vice versa

问题描述

我socket编程为Android（在Java中）。如何将我的插座转换成字符串并转换该字符串重新presentation回插座？

I'm socket programming for Android (in Java). How can I convert my socket to a string and convert that string representation back to a socket?

例如，假设有一个插座SS 。我要的是一些像这样的事情：

For example, consider a Socket ss. What I want is some thing like this:

String strss = ss.tostring();

和后来

Socket s = new Socket(strss);

我要保存的插座（即重建后的插座所需的详细信息）到数据库中（作为一个字符串）之后，我需要重新转换它插座我的应用程序使用它！

I want to save the Socket (i.e. the details needed to recreate that socket later) into a database (as a string) and after that I need to reconvert it to Socket to use it in my app!

推荐答案

奇怪的问题，但您可以提取您需要重新创建一个字符串插座的信息。
如果没有错误检查等：

Strange question but you can extract the info you need to recreate the socket from a string. Without error checking etc:

要字符串：

Socket s = ...;
String hostAndPort = s.getInetAddress().getHostAddress();
hostAndPort = hostAndPort + ":" + s.getPort();

然后回：

String host = hostAndPort.substring(0, hostAndPort.indexOf(':'));
int port = Integer.parseInt(hostAndPort.substring(hostAndPort.indexOf(':') + 1));
Socket s = new Socket(host, port);
