包路径：java.net.URLConnection
类名称：URLConnection
方法名：getHeaderFieldLong

URLConnection.getHeaderFieldLong介绍

[英]Returns the value of the named field parsed as a number.

This form of getHeaderField exists because some connection types (e.g., http-ng) have pre-parsed headers. Classes for that connection type can override this method and short-circuit the parsing.
[中]返回解析为数字的命名字段的值。
这种形式的getHeaderField之所以存在，是因为某些连接类型（例如http-ng）具有预解析的头。该连接类型的类可以重写此方法并缩短解析过程。
