go的net/http包使用
1,首先搞清[]byte string的相互转换，最简单的方式就是
string转[]byte：[]byte(para string)
[]byte转string：string([]byte)
然后还有就是io包的一些实现方式，比如：
- bytes.NewBuffer(para []byte）.String()
2,如何从request中获取form,body，head,下面是官方的api：
type Request
func NewRequest(method, urlStr string, body io.Reader) (*Request, error)
func ReadRequest(b *bufio.Reader) (req *Request, err error)
func (r *Request) ProtoAtLeast(major, minor int) bool
func (r *Request) UserAgent() string
func (r *Request) Referer() string
func (r *Request) AddCookie(c *Cookie)
func (r *Request) SetBasicAuth(username, password string)
func (r *Request) Write(w io.Writer) error
func (r *Request) WriteProxy(w io.Writer) error
func (r *Request) Cookies() []*Cookie
func (r *Request) Cookie(name string) (*Cookie, error)
func (r *Request) ParseForm() error
func (r *Request) ParseMultipartForm(maxMemory int64) error
func (r *Request) FormValue(key string) string
func (r *Request) PostFormValue(key string) string
func (r *Request) FormFile(key string) (multipart.File, *multipart.FileHeader, error)
func (r *Request) MultipartReader() (*multipart.Reader, error)
type Header
func (h Header) Get(key string) string
func (h Header) Set(key, value string)
func (h Header) Add(key, value string)
func (h Header) Del(key string)
func (h Header) Write(w io.Writer) error
func (h Header) WriteSubset(w io.Writer, exclude map[string]bool) error本文参与 腾讯云自媒体同步曝光计划，分享自微信公众号。
