英文:
Map variable amount of urls to HandleFunc
问题
这是我第一次尝试使用Go（Golang）编写一个小型博客。现在，我有一个只有几个页面的小型网站。我的main函数包含以下内容：
http.HandleFunc("/about", about)
http.HandleFunc("/contact", contact)
http.HandleFunc("/", homepage)
if err := http.ListenAndServe(":8080", nil); err != nil {
log.Fatalln(err)
}
我的第一个问题是：这被称为什么？我称之为将URL映射到函数，但是我的谷歌搜索结果并不理想。这被称为"路由"吗？
其次，我的目标是编写一个小型博客应用程序。我想使用数据库来保存博客文章和其他数据。然而，像我上面那样将URL映射到函数似乎不太合适，因为在有人发布博客文章之前，无法知道URL应该是什么。我希望URL与博客文章的标题匹配。此外，可能会有数百篇博客文章，因此编写大量的http.HandleFunc函数似乎不合理。
最后，我的问题是：有哪些选项可用来解决这个障碍？
英文:
This is the first time that I attempt to write a small blog using Go (Golang). Right now, I have a small website running with only a few pages. My main contains this.
http.HandleFunc("/about", about)
http.HandleFunc("/contact", contact)
http.HandleFunc("/", homepage)
if err := http.ListenAndServe(":8080", nil); err != nil {
log.Fatalln(err)
}
My first question is: What is this called? I call it mapping URLs to functions, but my Google results haven't been fruitful with those search terms. Is this called "routing"?
Secondly, my goal is to write a small blog app. I want to use a database to save blog posts and other data. However, mapping URLs to functions like I did above doesn't seem right because there is no way to know what the URL should be until someone makes a blog post. I would want the URL to match the blog post title. In addition, there could be hundreds of blog posts, so writing a bunch of http.HandleFuncs seems unreasonable.
Finally, my question is this: What options are available to solve this obstacle?

一个“博客应用”的另一种方法是使用静态网站生成器。你可以在gohugo（GitHub仓库）中找到一个很好的例子，这意味着你只有一个处理程序：
if port > 0 {
if !viper.GetBool("DisableLiveReload") {
livereload.Initialize()
http.HandleFunc("/livereload.js", livereload.ServeJS)
http.HandleFunc("/livereload", livereload.Handler)
}
go serve(port)
}
但更一般地说，它被称为路由器，你可以在这个出色的**Go语言第三方路由器指南 2014/11/20**中找到它们：
英文:
The other approach for a "blog app" is a static site generator.
You can find a good example in gohugo (repo GitHub), which means you only have one Handler:
if port > 0 {
if !viper.GetBool("DisableLiveReload") {
livereload.Initialize()
http.HandleFunc("/livereload.js", livereload.ServeJS)
http.HandleFunc("/livereload", livereload.Handler)
}
go serve(port)
}
But more generally, what it is called is a router, and you can see them in this excellent Guide to 3rd Party Routers in Go 2014/11/20:
