Gin 在加载 index.html 时总是报错

r := gin.New()
r.Use(gin.Logger())
r.Use(gin.Recovery())
r.LoadHTMLGlob("views/**/*")
r.GET("/", func(g *gin.Context) {
    g.HTML(http.StatusOK, "index/index.html", gin.H{
        "title":"test",
    })

【问题讨论】：

你能展示一个包结构吗？

标签： go go-gin

【解决方案1】：

如果您的 index.html 文件位于 views/index/index.html 中，则应使用此通配符。也尝试使用./。

r.LoadHTMLGlob("./views/*")
r.GET("/", func(g *gin.Context) {
  g.HTML(http.StatusOK, "index/index.html", gin.H{
    "title":"test",
  }
)

【解决方案2】：

这个问题似乎不是模板加载引起的，你能显示你的包信息或显示更多代码吗？

这是我的包裹：

views
-|index
-|-|index.html
main.go

main.go:

package main

import (
    "github.com/gin-gonic/gin"
    "net/http"
)

func main(){
    router := gin.Default()
    //define template dir
    router.LoadHTMLGlob("views/**/*")
    // handel router
    router.GET("/",func(c *gin.Context){
        c.HTML(http.StatusOK,"index/index.html",gin.H{
            "title":"test",
        })
    })

    router.Run(":8080")
}

views/index/index.html:

{{define "index/index.html"}}
    asdds
{{end}}

demo可以正常运行。我发现只有一个区别，如果你在LoadHTMLGlob中使用subdir，我应该在html中定义模板是这样的：

{{define "index/index.html"}}{{end}}
