I'm using Gin Gonic and an HTML template file.
My template file contains (multi-line) HTML comments similar to <!--This is my comment -->. I wish to preserve the HTML content in the returned output.
c.HTML(http.StatusOK, "static/templates/mytemplate.html", gin.H{
"name": "World",
})
Question: How to configure the template engine or c.HTML to not strip HTML comments in templates?
/static/templates/mytemplate.html:
<!DOCTYPE html> <html lang="de"> <body> <!-- 这些行在输出中缺失。 --> Hello World </body> </html>
My handler:
func NewRouter() *gin.Engine {
router := gin.Default()
// ... load templates from file system ...
router.GET("/foo", fooHandler)
return router
}
func fooHandler(c *gin.Context) {
c.HTML(http.StatusOK, "static/templates/mytemplate.html", gin.H{
"name": "World",
})
}
After editing, I tried adding the annotation as a constant :
{{"<!-- my comment goes here -->"}}
but the tag is escaped as
<!-- foo -->

I'm guessing the reason the HTML comments are removed is because I'm reading the HTML template as a string (instead of directly as a file). The exact cause still cannot be determined. Anyway, the solution that worked for me was to use placeholders in the template.
<!DOCTYPE html>
<html lang="de">
<body>
{{ .myComment }}
Hello World
</body>
</html>
and pass the HTML comment itself as a parameter:
const myHtmlComment string = `
<!--
these lines are (not) missing (anymore) in the output
-->
`
func fooHandler(c *gin.Context) {
c.HTML(http.StatusOK, "static/templates/mytemplate.html", gin.H{
"name": "World",
"myComment": template.HTML(myHtmlComment),
})
}
Use import "html/template" to import
