Golang Gin Session & Cookie

 1 func (con UserControl) Index(c *gin.Context) {
 2     /*** 设置Cookie
 3         func (c *Context) SetCookie(name, value string, maxAge int, path, domain string, secure, httpOnly bool) {
 4         参数:
 5             1. name       key
 6             2. value    value
 7             3. maxAge    过期时间(秒).如果只是想设置Cookie的保存路进而不详设置存活时间,可以在直接传nil,-1就是删除Cookie.
 8             4. path        Cookie的路径. "/"表示当前域都可以访问
 9             5. domain    Cookie路径Domain作用域.本地配制成localhost,正式上限配制成域名
10             6. secure    当为true时,cookie在http中是无效的,在https才有效
11             7. httpOnly    是微软堆cookie做的拓展. 如果在cookie中设置了true,则通过程序(JS脚本\applet等)将无法读取道Cookie信息,防止XSS攻击
