Golang Web服务器与Vue.js前端如何进行数据交互？

Golang Web服务器与Vue.js前端如何进行数据交互？ 我正在尝试理解如何在非常简洁的Go语言Web服务器和Vue.js前端之间交换数据。

这是 server-gorillamux.go 文件：

package main

import (
        "encoding/json"
        "github.com/gorilla/mux"
        "log"
        "net/http"
)

const (
        CONN_HOST = "192.168.1.7"
        CONN_PORT = "3000"
)

type Puser struct {
        first_name   string `json:"first_name"`
        last_name    string `json:"last_name"`
        company_name string `json:"company_name"`
        email        string `json:"email"`
        tel          string `json:"tel"`
}

type Pusers []Puser

var pusers []Puser

type Route struct {
        Name        string
        Method      string
        Pattern     string
        HandlerFunc http.HandlerFunc
}

type Routes []Route

var routes = Routes{
        Route{
                "getPusers",
                "GET",
                "/pusers",
                getPusers,
        },
        Route{
                "addPuser",
                "POST",
                "/puser/add",
                addPuser,
        },
}

func getPusers(w http.ResponseWriter, r *http.Request) {
        json.NewEncoder(w).Encode(pusers)
}

func addPuser(w http.ResponseWriter, r *http.Request) {
        puser := Puser{}
        err := json.NewDecoder(r.Body).Decode(&puser)
        if err != nil {
                log.Print("error occured while decoding puser data :: ", err)
        }
        log.Printf("adding puser id :: % s with firstName ■■■ :: %s and lastName as :: %s ",   
puser.first_name, puser.last_name)
        pusers = append(pusers, Puser{first_name: puser.first_name,
                last_name: puser.last_name, company_name: puser.company_name,
                email: puser.email, tel: puser.tel})
        json.NewEncoder(w).Encode(pusers)
}

func AddRoutes(router *mux.Router) *mux.Router {
        for _, route := range routes {
                router.
                        Methods(route.Method).
                        Path(route.Pattern).
                        Name(route.Name).
                        Handler(route.HandlerFunc)
        }
        return router
 }

func main() {
        muxRouter := mux.NewRouter().StrictSlash(true)
        router := AddRoutes(muxRouter)
        router.PathPrefix("/").Handler(http.FileServer(http.Dir("../src/components/auth/Forms.vue")))
        //router.PathPrefix("/").Handler(http.FileServer(http.Dir("../public/")))
        err := http.ListenAndServe(CONN_HOST+":"+CONN_PORT, router)
        if err != nil {
                log.Fatal("error starting http server :: ", err)
                return
        }
}

这是 /src/components/auth/Forms.vue 文件：

    <div class="signup-form">
      <form @submit.prevent="onSubmit">
        <div class="firstname">

      }
    } // end of methods

</script>

<style scoped>
    ....
</style>

执行Go语言Web服务器：

(base) marco@pc01:~/webMatters/vueMatters/GraspGlobalChances/goServer$ go run server-   
gorillamux.go

以及编译并运行Vue.js前端

完成 编译成功，耗时1960毫秒 下午4:37:20

应用程序运行于：

• 本地： http://localhost:8080
• 网络： http://ggc.world/

请注意，开发版本未进行优化。 要创建生产版本，请运行 npm run build。
