首次连接失败后插座未连接 [英] Socket not connecting after first connection failure

问题描述

我不明白为什么以下程序在初始连接失败时不起作用（我在第一次连接失败后故意启动服务器套接字）：

I don't understand why the following program doesn't work when the initial connect fails (I intentionally start the server socket after the first connect fails):

Socket client = new Socket();
while (true) {
    try {
        client.connect(address);
        break;
    } catch (IOException e) {
         Thread.sleep(1000);
    }
}

如果我移动客户端= while循环中的新Socket（）; ，它可以工作，但我在文档中找不到任何说明如果初始连接失败，套接字被损坏并且必须被回收。

If I move the client = new Socket(); inside the while loop, it works, but I couldn't find anything in the documentation that states that if an initial connect fails the socket is "broken" and has to be recycled.

推荐答案

您无法重新连接已连接失败的套接字。您必须关闭它并使用新套接字重试。您正在寻找的文档将是Berkeley套接字API级别，而不是Java，

You can't reconnect a socket that has already failed to connect. You have to close it and try again with a new socket. The documentation you're looking for would be at the Berkeley Sockets API level, not Java,
