func (dc *ArticleController) GetArticle(c *fiber.Ctx) error {
// 处理获取文章的逻辑
article := new(Article)
article.Id = 1
article.Title = "三国演义金圣叹批本"
article.Author = "罗贯中"
user:=c.Query("user")
myMap:=fiber.Map{}
myMap["Title"] = article.Title
myMap["Article"] = article
myMap["UserId"] = user
return c.Render("article/info", myMap)
}2,view
<!DOCTYPE html>
