本篇文章给大家分享《在swagger ui中如何展示模型》，覆盖了Golang的常见基础知识，其实一个语言的全部知识点一篇文章是不可能说完的，但希望通过这些问题，让读者对自己的掌握程度有一定的认识(B 数)，从而弥补自己的不足，更好的掌握它。

问题内容

我有一本用 golang 构建的书本 api，一切正常，我正在尝试为文档添加 swagger，我已经做到了，但我遇到了问题，我只能看到路线，但是当我点击它，看不到描述，也看不到任何型号信息，这是我在 main.go 上的代码

package main

import (
    //"fmt"

func main(){
    db_client.initialisedbconnection()

    r := gin.default()
    //r.use(cors.default())
    r.use(cors.new(cors.config{
        alloworigins:     []string{"http://localhost:8080"},

        allowheaders:     []string{"origin","authorization","x-api-key","content-type"},
        exposeheaders:    []string{"content-length"},
        allowcredentials: true,
        alloworiginfunc: func(origin string) bool {
            return origin == "http://localhost:8080"
        },
        maxage: 12 * time.hour,
    }))
    // router.handleroutes()
    r.post("api/v1/products/login", controller.login)
    r.post("api/v1/products/create", controller.createproducts)
    r.get("api/v1/products", controller.getproducts)

    r.delete("api/v1/products/:id/delete", controller.deletesingleproduct)
    //r.post("api/v1/products/check", controller.checkheader)

    r.get("/swagger/*any", ginswagger.wraphandler(swaggerfiles.handler))

    if err := r.run(":3000"); err != nil {
        panic(err.error())
    }
    // router.handleroutes()
    // fmt.println("server starting.. @ port :3000")
    // http.listenandserve(":3000", nil)

这是我在控制器上的代码

关于管理模型

package model

// admin example

type admin struct {
    id int64        `json: "id" example:"1"`
    username string     `json: "username" example:"admin name"`
    password string     `json: "password" example:"h56yggy7uj"`
}

我的帖子模型

package model

type Post struct {
    ID int64            `json: "id"`
    Title string        `json: "title"`
    Description *string     `json: "description"`
}

请我不知道我做错了什么，我需要帮助，因为我希望显示所有信息
