我尝试使用套接字创建SSLSocket,但得到此异常 SocketAddress proxyAddr = new InetSocketAddress(proxyHost, proxyPort); Socket underlying = new Socket(new Proxy(Proxy.Type.SOCKS, proxyAddr)); underlying.connect(new InetSocketAddress(host, port)); SSLSocket socket = (SSLSocket) factory.createSock...

连接超时参数ConnectTimeout 可自定义配置的建立连接最长等待时间 读取超时参数ReadTimeout 控制从Socket上读取数据的最长等待时间。 1.3 常见踩坑点 连接超时配置过长 比如60s。TCP三次握手正常建立连接所需时间很短,在ms级最多到s级,不可能需要十几、几十秒,多半是网络或防火墙配置问题。这时如果几秒还连不上,那...

To reduce latency, this class may reuse the same underlying Socket for multiple request/response pairs. As a result, HTTP connections may be held open longer than necessary. Calls to #disconnect() may return the socket to a pool of connected sockets. ...
