2.2.2 HttpURLConnection.connect()的拆解 从前面的分析可知,URL.openConnection()最终返回的是HttpURLConnectionImpl对象,所以HttpURLConnection.connect()其实就是HttpURLConnectionImpl.connect(),该方法如下: @Overridepublicfinalvoidconnect()throwsIOException{initHttpEngine();booleansuccess;do{success=execute(false)...
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...
创建Socket连接时,可以指定使用的传输层协议,Socket可以支持不同的传输层协议(TCP或UDP),当使用TCP协议进行连接时,该Socket连接就是一个TCP连接。 .NetFrameWork为Socket通讯提供了System.Net.Socket命名空间,在这个命名空间里面有以下几个常用的重要类分别是: ·Socket类这个低层的类用于管理连接,WebRequest,TcpClient和...

this might be a bit repetitive but, can you post the full log, like include the command line, just want to make sure there isn't anything before the [socket] - id=0x7efbe0004ca0 fd=26: connect failed with error code 101. line, do sanitize the sensitive info though. Author reinismu...
Underneath the 'Connect' timeout is really a set of TCP timeouts related to setting up the socket via the 3-leg SYN/ACK exchange. The TCP timeout is about retransmits with back-off and how many is tried by the Winsock stack. The default of these initial packet exchanges is 21 seconds...
