假设我只想获取一个页面的cookie信息，并关心它返回的内容，也就是不读取Response.Body，是否还需要自己去关闭一下body呢（Response.Body.Close()）？
第一次上来提问，方法不对的地方请见谅。
因该都不需要关闭手动关闭吧，下面是源码上面写的备注，说：
The Server will close the request body. The ServeHTTP
// Handler does not need to.
Body io.ReadCloser
// Body is the request's body.
//
// For client requests a nil body means the request has no
// body, such as a GET request. The HTTP Client's Transport
// is responsible for calling the Close method.
//
// For server requests the Request Body is always non-nil
// but will return EOF immediately when no body is present.
// The Server will close the request body. The ServeHTTP
// Handler does not need to.
Body io.ReadCloser
源码里面有如下：
func (c *conn) serve() {
....
serverHandler{c.server}.ServeHTTP(w, w.req)
if c.hijacked() {
return
}
w.finishRequest()
if w.closeAfterReply {
if w.requestBodyLimitHit {
c.closeWriteAndWait()
}
break
}
....
}
处理完毕以后标准库会自动关闭链接的。

是的，上一个是服务端，如果是模拟客户端的话应该都需要关闭的。
下面是源码注释：` // The http Client and Transport guarantee that Body is always
// non-nil, even on responses without a body or responses with
// a zero-length body. It is the caller's responsibility to
// close Body.`
