到这里前七天的任务已经完成，但我们可以对Gee框架进行一些扩展

补充HTTP请求方法

原作者只实现了 GET, POST 路由添加，其他的 PUT, DELETE 等标准 HTTP 方法未实现，实现方法也很简单，只需在gee.go中增加如下代码

// PUT defines the method to add PUT request
func (group *RouterGroup) PUT(pattern string, handler HandlerFunc) {group.addRoute(http.MethodPut, pattern, handler)
}// DELETE defines the method to add DELETE request
func (group *RouterGroup) DELETE(pattern string, handler HandlerFunc) {group.addRoute(http.MethodDelete, pattern, handler)
}// PATCH defines the method to add PATCH request
func (group *RouterGroup) PATCH(pattern string, handler HandlerFunc) {group.addRoute(http.MethodPatch, pattern, handler)
}// HEAD defines the method to add HEAD request
func (group *RouterGroup) HEAD(pattern string, handler HandlerFunc) {group.addRoute(http.MethodHead, pattern, handler)
}// OPTIONS defines the method to add OPTIONS request
func (group *RouterGroup) OPTIONS(pattern string, handler HandlerFunc) {group.addRoute(http.MethodOptions, pattern, handler)
}// TRACE defines the method to add TRACE request
func (group *RouterGroup) TRACE(pattern string, handler HandlerFunc) {group.addRoute(http.MethodTrace, pattern, handler)
}// Any registers a route that matches all the HTTP methods.
// GET, POST, PUT, DELETE, PATCH, HEAD, OPTIONS.
func (group *RouterGroup) Any(pattern string, handler HandlerFunc) {group.GET(pattern, handler)group.POST(pattern, handler)group.PUT(pattern, handler)group.DELETE(pattern, handler)group.PATCH(pattern, handler)group.HEAD(pattern, handler)group.OPTIONS(pattern, handler)group.TRACE(pattern, handler)
}

参考gin实现Cookie

在context.go文件中加入以下代码

// 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,Secure:   secure,HttpOnly: httpOnly,})
}// Cookie returns the named cookie provided in the request or
// ErrNoCookie if not found. And return the named cookie is unescaped.
// If multiple cookies match the given name, only one cookie will
// be returned.
func (c *Context) Cookie(name string) (string, error) {cookie, err := c.Req.Cookie(name)if err != nil {return "", err}val, _ := url.QueryUnescape(cookie.Value)return val, nil
}

使用方法：

r.GET("/setcookie", func(c *gee.Context) {c.SetCookie("gee_cookie", "gee_cookie", 3600, "/", "localhost", false, true)c.String(http.StatusOK, "set cookie: gee_cookie")
})r.GET("/getcookie", func(c *gee.Context) {cookie, _ := c.Cookie("gee_cookie")c.String(http.StatusOK, "get cookie: %s", cookie)
})
