Go语言实现关闭http请求的方式总结

type Response struct {
	Status     string // e.g. "200 OK"
	StatusCode int    // e.g. 200
	Proto      string // e.g. "HTTP/1.0"
	ProtoMajor int    // e.g. 1
	ProtoMinor int    // e.g. 0
	Header Header
	Body io.ReadCloser
	ContentLength int64
	Close bool
	Uncompressed bool
	Trailer Header
	Request *Request
	TLS *tls.ConnectionState
}

func main() {
	req, err := http.NewRequest("GET", "http://www.baidu.com", nil)
	checkError(err)

	req.Close = true

	resp, err := http.DefaultClient.Do(req)
	if resp != nil {
		defer resp.Body.Close()
	}
	checkError(err)

	body, err := ioutil.ReadAll(resp.Body)
	checkError(err)

	fmt.Println(string(body))

}

func checkError(err error) {
	if err != nil {
