ctx.SetCookie("ZJXUSS", res.ZJXUSS, 0, "/", ctx.Request.Host, false, true)
获取cookie
cookie, err := ctx.Cookie("ZJXUSS")
结合源码了解一下http协议里的cookie：
// SetCookie adds a Set-Cookie header to the ResponseWriter's headers.
// The provided cookie must have a valid Name. Invalid cookies may be
// silently dropped.
func (c *Context) SetCookie(name, value string, maxAge int, path, domain string, secure, httpOnly bool) {
if path == "" {
path = "/"
}
http.SetCookie(c.Writer, &http.Cookie{
Name: name,
Value: url.QueryEscape(value),
MaxAge: maxAge,
Path: path,
Domain: domain,
SameSite: c.sameSite,
Secure: secure,
HttpOnly: httpOnly,
})
}
gin的实际是封装了go的cookie操作http.SetCookie，第二个参数传的cookie的结构:
// A Cookie represents an HTTP cookie as sent in the Set-Cookie header of an
// HTTP response or the Cookie header of an HTTP request.
//
// See https://tools.ietf.org/html/rfc6265 for details.
type Cookie struct {
Name string
Value string
Path string // optional
Domain string // optional
Expires time.Time // optional
RawExpires string // for reading cookies only
// MaxAge=0 means no 'Max-Age' attribute specified.
// MaxAge<0 means delete cookie now, equivalently 'Max-Age: 0'
// MaxAge>0 means Max-Age attribute present and given in seconds
MaxAge int
Secure bool
HttpOnly bool
SameSite SameSite
Raw string
Unparsed []string // Raw text of unparsed attribute-value pairs
}
name、value: 要在cookie保存的键值对
maxAge: max-age，cookie保存时间
0: 不过期
-1: 不保存
>0: 保存多少秒
domain: 域名
secure: 防止信息传输泄漏
true: 只在https中传输，http不能传输
false: 可以在https、http中传输
httpOnly: 禁止js读取，防止xss攻击
