response代表来自http request的响应
先看看response的结构体定义
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 maps header keys to values. If the response had multiple
// headers with the same key, they may be concatenated, with comma
// delimiters. (Section 4.2 of RFC 2616 requires that multiple headers
// be semantically equivalent to a comma-delimited sequence.) Values
// duplicated by other fields in this struct (e.g., ContentLength) are
// omitted from Header.
//
// Keys in the map are canonicalized (see CanonicalHeaderKey).
Header Heade
// 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. The default HTTP client's Transport does not
// attempt to reuse HTTP/1.0 or HTTP/1.1 TCP connections
// ("keep-alive") unless the Body is read to completion and is
// closed.
//
// The Body is automatically dechunked if the server replied
// with a "chunked" Transfer-Encoding.
Body io.ReadCloser // response body部分 ,读完之后就被关闭
ContentLength int64 // 表示传输的文本长度
// Contains transfer encodings from outer-most to inner-most. Value is
// nil, means that "identity" encoding is used.
TransferEncoding []string
Close bool
// Trailer maps trailer keys to values in the same
// format as Header.
//
// The Trailer initially contains only nil values, one fo
// each key specified in the server's "Trailer" heade
// value. Those values are not added to Header.
//
// Trailer must not be accessed concurrently with Read calls
// on the Body.
//
// After Body.Read has returned io.EOF, Trailer will contain
// any trailer values sent by the server.
Trailer Heade
// The Request that was sent to obtain this Response.
// Request's Body is nil (having already been consumed).
// This is only populated for Client requests.
Request *Request
// TLS contains information about the TLS connection on which the
// response was received. It is nil for unencrypted responses.
// The pointer is shared between responses and should not be
// modified.
TLS *tls.ConnectionState
