本文整理了Java中org.apache.http.HttpConnection类的一些代码示例，展示了HttpConnection类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。HttpConnection类的具体详情如下：
包路径：org.apache.http.HttpConnection
类名称：HttpConnection

HttpConnection介绍

[英]A generic HTTP connection, useful on client and server side.
[中]通用HTTP连接，在客户端和服务器端都很有用。

context.getAttribute(ExecutionContext.HTTP_CONNECTION);
if (conn != null && !conn.isOpen())
  return false;

public void closeExpiredConnections() {
  long now = System.currentTimeMillis();
  if (log.isDebugEnabled()) {
    log.debug("Checking for expired connections, now: "  + now);
  }
  
  Iterator<HttpConnection> connectionIter =
    connectionToTimes.keySet().iterator();
  
  while (connectionIter.hasNext()) {
    HttpConnection conn = connectionIter.next();
    TimeValues times = connectionToTimes.get(conn);
    if(times.timeExpires <= now) {
      if (log.isDebugEnabled()) {
        log.debug("Closing connection, expired @: "  + times.timeExpires);
      }
      connectionIter.remove();
      try {
        conn.close();
      } catch (IOException ex) {
        log.debug("I/O error closing connection", ex);
      }
    }
  }        
}
