URLConnection 已连接 getter
URLConnection connected getter
我正在检查 URLConnection class 的文档,但找不到 connected 字段的 getter/setter .虽然有 getDoInput() ,但没有 isConnected()。所以我想知道是否有方法或其他方法来检查这个。
如果已经有连接,您可以简单地调用 connect()
没有任何反应。
参见connect
方法的文档:
If the connect method is called when the connection has already been
opened (indicated by the connected field having the value true), the
call is ignored.
