为什么我'；在使用java阅读网页时，我会得到http头和非html数据吗？

我尝试了几种从internet获取数据的代码，但所有代码都会将标题与我要保存的文件一起获取：

类似以下代码：

URL url;
String webURL = "http://www.wunderground.com/history/airport/EGLL/2010/11/30/DailyHistory.html?HideSpecis=1&format=1";
url = new URL(webURL);
ReadableByteChannel rbc = Channels.newChannel(url.openStream());
FileOutputStream fos = new FileOutputStream("c:\\weather.txt");
fos.getChannel().transferFrom(rbc, 0, 1 << 24);

URL；
字符串webURL=”http://www.wunderground.com/history/airport/EGLL/2010/11/30/DailyHistory.html?HideSpecis=1&format=1";
url=新url（webURL）；
ReadableByteChannel rbc=Channels.newChannel（url.openStream（））；
FileOutputStream fos=新的FileOutputStream（“c:\\weather.txt”）；
fos.getChannel（）.transferFrom（rbc，0，1如果您阅读RFC（），您可以看到来自服务器的所有响应（即Http响应）都包含一个标头

在web浏览器中，这对用户来说是完全透明的，因为响应头包含一些与检索到的内容或发出的请求相关的信息

如果您只想要内容，则必须从邮件中获取响应实体，忽略所述响应的标题，然后将其保存到您想要的文件中。
为什么不使用Apache Commons的HTTPClient？它将为您和“标题”提供标题在java中是否有任何特定的方法可以只获取响应？对于请求，您应该使用Apache HttpComponents，有很多关于如何开始使用它的示例：
