方法名：getHeaderFieldKey

HttpURLConnection.getHeaderFieldKey介绍

[英]Returns the key for the nth header field. Some implementations may treat the 0th header field as special, i.e. as the status line returned by the HTTP server. In this case, #getHeaderField(int) returns the status line, but getHeaderFieldKey(0) returns null.
[中]返回第n个标头字段的键。某些实现可能将第0个头字段视为特殊字段，即HTTP服务器返回的状态行。在本例中，#getHeaderField（int）返回状态行，但getHeaderFieldKey(0)返回null。
