Types

type Browse

type Browse struct {
	// Use this template file instead of the default browse template.
	TemplateFile string `json:"template_file,omitempty"`
	// contains filtered or unexported fields
}

Browse configures directory browsing.

type FileServer

type FileServer struct {
	// The path to the root of the site. Default is `{http.vars.root}` if set,
	// or current working directory otherwise.
	Root string `json:"root,omitempty"`

	// A list of files or folders to hide; the file server will pretend as if
	// they don't exist. Accepts globular patterns like "*.ext" or "/foo/*/bar"
	// as well as placeholders. Because site roots can be dynamic, this list
	// uses file system paths, not request paths. To clarify, the base of
	// relative paths is the current working directory, NOT the site root.
	//
	// Entries without a path separator (`/` or `\` depending on OS) will match
	// any file or directory of that name regardless of its path. To hide only a
	// specific file with a name that may not be unique, always use a path
	// separator. For example, to hide all files or folder trees named "hidden",
	// put "hidden" in the list. To hide only ./hidden, put "./hidden" in the list.
	//
	// When possible, all paths are resolved to their absolute form before
	// comparisons are made. For maximum clarity and explictness, use complete,
	// absolute paths; or, for greater portability, use relative paths instead.
	Hide []string `json:"hide,omitempty"`

	// The names of files to try as index files if a folder is requested.
	IndexNames []string `json:"index_names,omitempty"`

	// Enables file listings if a directory was requested and no index
	// file is present.
	Browse *Browse `json:"browse,omitempty"`

	// Use redirects to enforce trailing slashes for directories, or to
	// remove trailing slash from URIs for files. Default is true.
	CanonicalURIs *bool `json:"canonical_uris,omitempty"`

	// Override the status code written when successfully serving a file.
	// Particularly useful when explicitly serving a file as display for
	// an error, like a 404 page. A placeholder may be used. By default,
	// the status code will typically be 200, or 206 for partial content.
	StatusCode caddyhttp.WeakString `json:"status_code,omitempty"`

	// If pass-thru mode is enabled and a requested file is not found,
	// it will invoke the next handler in the chain instead of returning
	// a 404 error. By default, this is false (disabled).
	PassThru bool `json:"pass_thru,omitempty"`

	// Selection of encoders to use to check for precompressed files.
	PrecompressedRaw caddy.ModuleMap `json:"precompressed,omitempty" caddy:"namespace=http.precompressed"`

	// If the client has no strong preference (q-factor), choose these encodings in order.
	// If no order specified here, the first encoding from the Accept-Encoding header
	// that both client and server support is used
	PrecompressedOrder []string `json:"precompressed_order,omitempty"`
	// contains filtered or unexported fields
}

FileServer implements a static file server responder for Caddy.

func (FileServer) CaddyModule

func (FileServer) CaddyModule() caddy.ModuleInfo

CaddyModule returns the Caddy module information.

func (*FileServer) Provision

func (fsrv *FileServer) Provision(ctx caddy.Context) error

Provision sets up the static files responder.

func (*FileServer) ServeHTTP

func (fsrv *FileServer) ServeHTTP(w http.ResponseWriter, r *http.Request, next caddyhttp.Handler) error

type MatchFile

type MatchFile struct {
	// The root directory, used for creating absolute
	// file paths, and required when working with
	// relative paths; if not specified, `{http.vars.root}`
	// will be used, if set; otherwise, the current
	// directory is assumed. Accepts placeholders.
	Root string `json:"root,omitempty"`

	// The list of files to try. Each path here is
	// considered related to Root. If nil, the request
	// URL's path will be assumed. Files and
	// directories are treated distinctly, so to match
	// a directory, the filepath MUST end in a forward
	// slash `/`. To match a regular file, there must
	// be no trailing slash. Accepts placeholders.
	TryFiles []string `json:"try_files,omitempty"`

	// How to choose a file in TryFiles. Can be:
	//
	// - first_exist
	// - smallest_size
	// - largest_size
	// - most_recently_modified
	//
	// Default is first_exist.
	TryPolicy string `json:"try_policy,omitempty"`

	// A list of delimiters to use to split the path in two
	// when trying files. If empty, no splitting will
	// occur, and the path will be tried as-is. For each
	// split value, the left-hand side of the split,
	// including the split value, will be the path tried.
	// For example, the path `/remote.php/dav/` using the
	// split value `.php` would try the file `/remote.php`.
	// Each delimiter must appear at the end of a URI path
	// component in order to be used as a split delimiter.
	SplitPath []string `json:"split_path,omitempty"`
}

MatchFile is an HTTP request matcher that can match requests based upon file existence.

Upon matching, three new placeholders will be made available:

- `{http.matchers.file.relative}` The root-relative path of the file. This is often useful when rewriting requests. - `{http.matchers.file.absolute}` The absolute path of the matched file. - `{http.matchers.file.type}` Set to "directory" if the matched file is a directory, "file" otherwise. - `{http.matchers.file.remainder}` Set to the remainder of the path if the path was split by `split_path`.

func (MatchFile) CaddyModule

func (MatchFile) CaddyModule() caddy.ModuleInfo

CaddyModule returns the Caddy module information.

func (MatchFile) Match

func (m MatchFile) Match(r *http.Request) bool

Match returns true if r matches m. Returns true if a file was matched. If so, four placeholders will be available:

  • http.matchers.file.relative
  • http.matchers.file.absolute
  • http.matchers.file.type
  • http.matchers.file.remainder

func (*MatchFile) Provision

func (m *MatchFile) Provision(_ caddy.Context) error

Provision sets up m's defaults.

func (*MatchFile) UnmarshalCaddyfile

func (m *MatchFile) UnmarshalCaddyfile(d *caddyfile.Dispenser) error

UnmarshalCaddyfile sets up the matcher from Caddyfile tokens. Syntax:

file <files...> {
    root <path>
    try_files <files...>
    try_policy first_exist|smallest_size|largest_size|most_recently_modified
}

func (MatchFile) Validate

func (m MatchFile) Validate() error

Validate ensures m has a valid configuration.
