gin HTMLGlob not applying **
问题
我有一个使用模板的 gin v1.8.1 Go 程序。主要的 Go 文件是 cmd/app/app.go
。在其中,我有以下代码:
r := gin.Default()
cwd, err := os.Getwd()
if err != nil {
panic(err)
}
fmt.Printf("CWD is %s", cwd)
r.LoadHTMLGlob("../../templates/**/*")
当我运行时,会出现以下 panic 错误:
CWD is /Users/paul/src/personal/app/cmd/app
panic: html/template: pattern matches no files: `../../templates/**/*`
goroutine 1 [running]:
html/template.Must(0x0, {0x4aac5a0, 0xc000584490})
/usr/local/Cellar/go/1.18.3/libexec/src/html/template/template.go:374 +0x8b
github.com/gin-gonic/gin.(*Engine).LoadHTMLGlob(0xc0005b04e0, {0x4a2e2ae, 0x14})
/Users/paul/go/pkg/mod/github.com/gin-gonic/gin@v1.8.1/gin.go:251 +0x15e
main.main()
/Users/paul/src/personal/app/cmd/app/app.go:31 +0x169
当我移除双星号 (r.LoadHTMLGlob("../../templates/*")
) 后,它可以正常工作。我知道标准库的 globber 不支持双星号,但是 gin 文档 中说他们的 globber 支持双星号。
英文:
I have a gin v1.8.1 go program that uses templates. Main go file is cmd/app/app.go
. Inside it, I have this
r := gin.Default()
cwd, err := os.Getwd()
if err != nil {
panic(err)
}
fmt.Printf("CWD is %s", cwd)
r.LoadHTMLGlob("../../templates/**/*")
When I run I get this panic
CWD is /Users/paul/src/personal/app/cmd/app
panic: html/template: pattern matches no files: `../../templates/**/*`
goroutine 1 [running]:
html/template.Must(0x0, {0x4aac5a0, 0xc000584490})

When I remove the double star (r.LoadHTMLGlob("../../templates/*")
), it works fine. I know the standard library globber does not handle double star, but gin docs says theirs does

显然,我刚刚误解了这个globbing实现的工作原理。我添加了一个新的模板test/index.html
,并尝试使用语法../../templates/**/*
。在调试模式下运行的Gin会列出它找到的所有模板。但它只找到了index.html
,而没有列出基本目录中的其他模板。**
的意思是匹配一个必须存在的目录。
英文:
Apparently I have just misunderstood how this implementation of globbing works. I added a new template, test/index.html
and tried the syntax ../../templates/**/*
. Gin running in debug mode lists all of the templates it finds. Rather than listing the templates in the base directory, it only finds index.html
. The **
means match a directory that must exist.
