how to serve html file with using router in gin?
问题
我正在使用gin框架练习制作Web服务器，并尝试向Web浏览器提供'index.html'文件。所以，我搜索了如何管理它，并编写了下面的代码，但出现了'HTTP错误500'。我应该在哪里修改代码？
main.go
package main
import (
"comento/works/pkg/router"
)
func main(){
r := router.Router()
r.Run(":8081")
}
router.go
package router
import (
"github.com/gin-gonic/gin"
"net/http"
)
func Router() *gin.Engine {
r := gin.Default()
r.GET("/", func(c *gin.Context) {
c.Header("Content-Type", "text/html")
c.HTML(http.StatusOK, "index.html", gin.H{})
})
return r
}
目录结构如下：
works
.
├── go.mod
├── go.sum
├── images
├── index
│ └── index.html
├── internal
│ └── global.go
├── main.go
└── pkg
├── api
│ └── image.go
└── router
└── router.go

以下是代码的翻译部分：
您的代码出现以下错误：
> 运行时错误：无效的内存地址或空指针解引用
您需要告诉 Gin 先加载 HTML 文件，可以使用以下方法：
func (*gin.Engine).LoadHTMLFiles(files ...string)或者func (*gin.Engine).LoadHTMLGlob(pattern string)
在您的情况下，根据提供的目录结构，可以这样写：
func Router() *gin.Engine {
r := gin.Default()
r.LoadHTMLFiles("index/index.html") // 可以像这样加载单个文件
// r.LoadHTMLGlob("index/*") // 或者使用通配符模式
r.GET("/", func(c *gin.Context) {
c.HTML(http.StatusOK, "index.html", gin.H{})
})
return r
}
英文:
The following error occurs with your code:
> runtime error: invalid memory address or nil pointer dereference
You have to tell Gin to load the HTML files first using:
func (*gin.Engine).LoadHTMLFiles(files ...string)orfunc (*gin.Engine).LoadHTMLGlob(pattern string)
In your case with your provided directory structure:
func Router() *gin.Engine {
r := gin.Default()
r.LoadHTMLFiles("index/index.html") // either individual files like this
// r.LoadHTMLGlob("index/*") // or a glob pattern
r.GET("/", func(c *gin.Context) {
c.HTML(http.StatusOK, "index.html", gin.H{})
})
return r
}

根据文档，静态文件的服务代码如下：
r.StaticFS("/index.html", http.Dir("<your_directory_name>"))
英文:
Accorfing to Documents serving static file is as followings:
r.StaticFS("/index.html", http.Dir("<your_directory_name>"))
