函数体外部的非声明语句

Question

我用Go为API写了一些关于“Go Web Development Cookbook.pdf”的代码。我在运行代码时遇到错误。我用切片声明了一个罢工和首字母，在切片中我做了两个项目切片，但是当我去这个时，它显示“函数体外的非声明语句”，我在互联网上搜索了解决方案。这是我的代码：package mainimport(    "fmt"    "encoding/json"    "log"    "net/http"    "github.com/gorilla/mux")const(    CONN_HOST = "localhost"    CONN_PORT = "8080")type Route struct{    Name string    Method string    Pattern string    HandlerFunc http.HandlerFunc}type Routes [] Routevar routes = Routes{    Route    {        "getEmployees",        "GET",        "/employees",        getEmployees,    },    Route    {        "getEmployee",        "GET",        "/employee/{id}",        getEmployee,    },}type Employee struct{    Id string `json:"id"`    FirstName string `json:"firstName"`    LastName string `json:"lastName"`}type Employees []Employeevar employees []Employeefunc init() {    employees = employees {        Employee{Id: "1", FirstName: "Foo", LastName: "Bar"},        Employee{Id: "2", FirstName: "Baz", LastName: "Qux"},    }}func getEmployees(w http.ResponseWriter, r *http.Request) {    json.NewEncoder(w).Encode(employees)}func getEmployee(w http.ResponseWriter, r *http.Request) {    vars := mux.Vars(r)    id := vars["id"]    for _, employee := range employees {        if employee.Id == id {            if err := json.NewEncoder(w).Encode(employee); err != nil {                log.Print("error getting requested employee :: ", err)            }        }    }}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)    err := http.ListenAndServe(CONN_HOST+":"+CONN_PORT, router)    if err != nil {        log.Fatal("error starting http server :: ", err)        return    }}“var 路由 = 路由”行表示错误。

Answer 1

你的代码格式有问题，在你需要保持放置大括号的约定，你不能把它放在另一行，你需要这样做：Go

var routes = Routes{

    Route{

        "getEmployees",

        "GET",

        "/employees",

        getEmployees,

    },

    Route{

        "getEmployee",

        "GET",

        "/employee/{id}",

        getEmployee,

    },

}
