### Server options

Use ` + "`--addr`" + ` to specify which IP address and port the server should
listen on, e.g. ` + "`--addr 1.2.3.4:8000` or `--addr :8080`" + ` to
listen to all IPs.  By default it only listens on localhost.  You can use port
:0 to let the OS choose an available port.

If you set ` + "`--addr`" + ` to listen on a public or LAN accessible IP address
then using Authentication is advised - see the next section for info.

` + "`--server-read-timeout` and `--server-write-timeout`" + ` can be used to
control the timeouts on the server.  Note that this is the total time
for a transfer.

` + "`--max-header-bytes`" + ` controls the maximum number of bytes the server will
accept in the HTTP header.

` + "`--baseurl`" + ` controls the URL prefix that rclone serves from.  By default
rclone will serve from the root.  If you used ` + "`--baseurl \"/rclone\"`" + ` then
rclone would serve from a URL starting with "/rclone/".  This is
useful if you wish to proxy rclone serve.  Rclone automatically
inserts leading and trailing "/" on ` + "`--baseurl`" + `, so ` + "`--baseurl \"rclone\"`" + `,
` + "`--baseurl \"/rclone\"` and `--baseurl \"/rclone/\"`" + ` are all treated
identically.

` + "`--template`" + ` allows a user to specify a custom markup template for HTTP
and WebDAV serve functions.  The server exports the following markup
to be used within the template to server pages:

| Parameter   | Description |
| :---------- | :---------- |
| .Name       | The full path of a file/directory. |
| .Title      | Directory listing of .Name |
| .Sort       | The current sort used.  This is changeable via ?sort= parameter |
|             | Sort Options: namedirfirst,name,size,time (default namedirfirst) |
| .Order      | The current ordering used.  This is changeable via ?order= parameter |
|             | Order Options: asc,desc (default asc) |
| .Query      | Currently unused. |
| .Breadcrumb | Allows for creating a relative navigation |
|-- .Link     | The relative to the root link of the Text. |
|-- .Text     | The Name of the directory. |
| .Entries    | Information about a specific file/directory. |
|-- .URL      | The 'url' of an entry.  |
|-- .Leaf     | Currently same as 'URL' but intended to be 'just' the name. |
|-- .IsDir    | Boolean for if an entry is a directory or not. |
|-- .Size     | Size in Bytes of the entry. |
|-- .ModTime  | The UTC timestamp of an entry. |

#### Authentication

By default this will serve files without needing a login.

You can either use an htpasswd file which can take lots of users, or
set a single username and password with the ` + "`--user` and `--pass`" + ` flags.

Use ` + "`--htpasswd /path/to/htpasswd`" + ` to provide an htpasswd file.  This is
in standard apache format and supports MD5, SHA1 and BCrypt for basic
authentication.  Bcrypt is recommended.

To create an htpasswd file:

    touch htpasswd
    htpasswd -B htpasswd user
    htpasswd -B htpasswd anotherUser

The password file can be updated while rclone is running.

Use ` + "`--realm`" + ` to set the authentication realm.

#### SSL/TLS

By default this will serve over HTTP.  If you want you can serve over
HTTPS.  You will need to supply the ` + "`--cert` and `--key`" + ` flags.
If you wish to do client side certificate validation then you will need to
supply ` + "`--client-ca`" + ` also.

` + "`--cert`" + ` should be either a PEM encoded certificate or a concatenation
of that with the CA certificate.  ` + "`--key`" + ` should be the PEM encoded
private key and ` + "`--client-ca`" + ` should be the PEM encoded client
certificate authority certificate.

--min-tls-version is minimum TLS version that is acceptable. Valid
  values are "tls1.0", "tls1.1", "tls1.2" and "tls1.3" (default
  "tls1.0").

Help contains text describing the http server to add to the command help.

Functions

Types

type AuthFn

type AuthFn func(user, pass string) (value interface{}, err error)

AuthFn if used will be used to authenticate user, pass. If an error is returned then the user is not authenticated.

If a non nil value is returned then it is added to the context under the key

type Options

type Options struct {
	ListenAddr         string        // Port to listen on
	BaseURL            string        // prefix to strip from URLs
	ServerReadTimeout  time.Duration // Timeout for server reading data
	ServerWriteTimeout time.Duration // Timeout for server writing data
	MaxHeaderBytes     int           // Maximum size of request header
	SslCert            string        // SSL PEM key (concatenation of certificate and CA certificate)
	SslKey             string        // SSL PEM Private key
	ClientCA           string        // Client certificate authority to verify clients with
	HtPasswd           string        // htpasswd file - if not provided no authentication is done
	Realm              string        // realm for authentication
	BasicUser          string        // single username for basic auth if not using Htpasswd
	BasicPass          string        // password for BasicUser
	Auth               AuthFn        `json:"-"` // custom Auth (not set by command line flags)
	Template           string        // User specified template
	MinTLSVersion      string        // MinTLSVersion contains the minimum TLS version that is acceptable
}

Options contains options for the http Server

type Server

type Server struct {
	Opt Options

	HTMLTemplate *template.Template // HTML template for web interface
	// contains filtered or unexported fields
}

Server contains info about the running http server

func NewServer

func NewServer(handler http.Handler, opt *Options) *Server

NewServer creates an http server. The opt can be nil in which case the default options will be used.

func (*Server) Close

func (s *Server) Close()

Close shuts the running server down

func (*Server) Path

func (s *Server) Path(w http.ResponseWriter, r *http.Request) (Path string, ok bool)

Path returns the current path with the Prefix stripped

If it returns false, then the path was invalid and the handler should exit as the error response has already been sent

func (*Server) Serve

func (s *Server) Serve() error

Serve runs the server - returns an error only if the listener was not started; does not block, so use s.Wait() to block on the listener indefinitely.

func (*Server) URL

func (s *Server) URL() string

URL returns the serving address of this server

func (*Server) UsingAuth

func (s *Server) UsingAuth() bool

UsingAuth returns true if authentication is required

func (*Server) Wait

func (s *Server) Wait()

Wait blocks while the listener is open.
