I am trying to use http templates in Go to render all the files in a specific folder on the webpage in a list. Every file or folder should also link to it's respective path. I've achieved reading all the items in a folder and saving them to these structs
type Item struct {
Name string
IsFolder bool
Info os.FileInfo
}
// Items contains a slice of all items in a folder
type Items struct {
Parent string
Items []Item
}
This is then passed on to a template.ExecuteTemplate function. The template in question looks like this:
<html>
<head>
<title>website</title>
</head>
<body>
<h1>Welcome to my website</h1>
<p>Files in {{.Parent}}</p>
<ul>
<li><a href="ftp?f={{ .Parent }}">{{.Parent}}</a></li>
{{range .Items}} {{if .IsFolder}}
<li><a href="ftp?f={{ .Parent }}/{{ .Name }}">{{ .Name }}</a></li>
{{else}}
<li><a href="ftp?f={{ .Parent }}/{{ .Name }}">{{.Name}}</a></li>
{{end}} {{end}}
</ul>
</body>
</html>
My problem however, is that when loading the page, the only thing that is returned is the beginning up until
<li><a href="ftp?f={{ .Parent }}/{{ .Name }}">{{ .Name }}</a></li>
And it stops right after the ?f= Now, I've tested it before with only {{ .Name }} and that worked absolutely fine, except of course, the link doesn't go anywhere. Rendering {{ .Parent }} in the list place above that one works absolutely fine. It also doesn't work if I simply remove the /, that produces exactly the same problem.
Of course my question is Why this happens and how I would go about fixing it.
Ps. you might notice a small security vulnerability, that if you put ../ in the ftp?f= field, you go up the filetree. Yes I know about this, and I will try and fix that. If you have a suggestion on how to fix that, you can also tell me :)
