使用Go写后端架构（二）
上一周的学习中，已经将一个简易的后端demo写完，现在需要进一步完善。
网页分为1个主页和5个子页面
通过编写不同的页面跳转函数来实现后端的内部结构：
func HomePage(w http.ResponseWriter, r *http.Request) {
if r.Method == "GET" {
t, _ := template.ParseFiles("./h5/homepage.html")
t.Execute(w, nil)
}
}
func SubPage1(w http.ResponseWriter, r *http.Request) {
if r.Method == "GET" {
t, _ := template.ParseFiles("./h5/subpage_1.html")
t.Execute(w, nil)
}
}
func SubPage2(w http.ResponseWriter, r *http.Request) {
if r.Method == "GET" {
t, _ := template.ParseFiles("./h5/subpage_2.html")
t.Execute(w, nil)
}
}
func SubPage3(w http.ResponseWriter, r *http.Request) {
if r.Method == "GET" {
t, _ := template.ParseFiles("./h5/subpage_3.html")
t.Execute(w, nil)
}
}
func SubPage4(w http.ResponseWriter, r *http.Request) {
if r.Method == "GET" {
t, _ := template.ParseFiles("./h5/subpage_4.html")
t.Execute(w, nil)
}
}
func SubPage5(w http.ResponseWriter, r *http.Request) {
if r.Method == "GET" {
t, _ := template.ParseFiles("./h5/subpage_5.html")
t.Execute(w, nil)
}
}
再通过get函数获取url信息进行跳转：
func API(w http.ResponseWriter, r *http.Request) {
if r.Method == "GET" {
r.ParseForm()
content := r.Form["content"][0]
resp1, _ := http.Get(strings.Join([]string{"http://127.0.0.1:1024/?content=", content}, ""))
defer resp1.Body.Close()
body, _ := ioutil.ReadAll(resp1.Body)
resp2, _ := http.Get(strings.Join([]string{"http://127.0.0.1:1025/?vec=", string(body)}, ""))
defer resp2.Body.Close()
ret, _ := ioutil.ReadAll(resp2.Body)
fmt.Fprintf(w, string(ret))
}
}
同时，在go编译器需要现运行的main中绑定相关函数与后缀名：
func main() {
http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
if r.URL.Path != "/" {
t, _ := template.ParseFiles("h5/404.html")
t.Execute(w, nil)
}
})
http.Handle("/css/", http.StripPrefix("/css/", http.FileServer(http.Dir("./css/")))) //定义静态资源的路由
http.Handle("/js/", http.StripPrefix("/js/", http.FileServer(http.Dir("./js/")))) //定义静态资源的路由
http.Handle("/img/", http.StripPrefix("/img/", http.FileServer(http.Dir("./img/")))) //定义静态资源的路由
http.Handle("/h5/", http.StripPrefix("/h5/", http.FileServer(http.Dir("./h5/")))) //定义静态资源的路由
http.HandleFunc("/review", server.HomePage)
http.HandleFunc("/cnn", server.SubPage1)
http.HandleFunc("/rnn", server.SubPage2)
http.HandleFunc("/svm", server.SubPage3)
http.HandleFunc("/nb", server.SubPage4)
http.HandleFunc("/lycoris", server.SubPage5)
http.HandleFunc("/api", server.API)
err := http.ListenAndServe(":1023", nil)
if err != nil {
log.Fatal("ListenAndServe: ", err)
}
}
