View Source 
var EmptyNext = HandlerFunc(func(w http.ResponseWriter, r *http.Request) (int, error) { return 0, nil })

EmptyNext is a no-op function that can be passed into Middleware functions so that the assignment to the Next field of the Handler can be tested.

Used primarily for testing but needs to be exported so plugins can use this as a convenience.

View Source 
var TemplateFuncs = template.FuncMap{}

TemplateFuncs contains user-defined functions for execution in templates.

Functions

func ContextInclude 

func ContextInclude(filename string, ctx interface{}, fs http.FileSystem) (string, error)

ContextInclude opens filename using fs and executes a template with the context ctx. This does the same thing that Context.Include() does, but with the ability to provide your own context so that the included files can have access to additional fields your type may provide. You can embed Context in your type, then override its Include method to call this function with ctx being the instance of your type, and fs being Context.Root.

func DefaultErrorFunc 

func DefaultErrorFunc(w http.ResponseWriter, r *http.Request, status int)

DefaultErrorFunc responds to an HTTP request with a simple description of the specified HTTP status code.

func IfMatcherKeyword 

func IfMatcherKeyword(c *caddy.Controller) bool

IfMatcherKeyword checks if the next value in the dispenser is a keyword for 'if' config block. If true, remaining arguments in the dispinser are cleard to keep the dispenser valid for use.

func IndexFile 

func IndexFile(root http.FileSystem, fpath string, indexFiles []string) (string, bool)

IndexFile looks for a file in /root/fpath/indexFile for each string in indexFiles. If an index file is found, it returns the root-relative path to the file and true. If no index file is found, empty string and false is returned. fpath must end in a forward slash '/' otherwise no index files will be tried (directory paths must end in a forward slash according to HTTP).

All paths passed into and returned from this function use '/' as the path separator, just like URLs. IndexFle handles path manipulation internally for systems that use different path separators.

func IsLogRollerSubdirective added in v0.10.0 

func IsLogRollerSubdirective(subdir string) bool

IsLogRollerSubdirective is true if the subdirective is for the log roller.

func MaxBytesReader added in v0.9.4 

func MaxBytesReader(w http.ResponseWriter, r io.ReadCloser, n int64) io.ReadCloser

MaxBytesReader and its associated methods are borrowed from the Go Standard library (comments intact). The only difference is that it returns a MaxBytesExceeded error instead of a generic error message when the request body has exceeded the requested limit

func ParseRoller 

func ParseRoller(l *LogRoller, what string, where string) error

ParseRoller parses roller contents out of c.

func RegisterDevDirective added in v0.9.2 

func RegisterDevDirective(name, before string)

RegisterDevDirective splices name into the list of directives immediately before another directive. This function is ONLY for plugin development purposes! NEVER use it for a plugin that you are not currently building. If before is empty, the directive will be appended to the end of the list.

It is imperative that directives execute in the proper order, and hard-coding the list of directives guarantees a correct, absolute order every time. This function is convenient when developing a plugin, but it does not guarantee absolute ordering. Multiple plugins registering directives with this function will lead to non- deterministic builds and buggy software.

Directive names must be lower-cased and unique. Any errors here are fatal, and even successful calls print a message to stdout as a reminder to use it only in development.

func SafePath added in v0.10.1 

func SafePath(siteRoot, reqPath string) string

SafePath joins siteRoot and reqPath and converts it to a path that can be used to access a path on the local disk. It ensures the path does not traverse outside of the site root.

If opening a file, use http.Dir instead.

func SameNext 

func SameNext(next1, next2 Handler) bool

SameNext does a pointer comparison between next1 and next2.

Used primarily for testing but needs to be exported so plugins can use this as a convenience.

func SetLastModifiedHeader 

func SetLastModifiedHeader(w http.ResponseWriter, modTime time.Time)

SetLastModifiedHeader checks if the provided modTime is valid and if it is sets it as a Last-Modified header to the ResponseWriter. If the modTime is in the future the current time is used instead.

func WriteTextResponse 

func WriteTextResponse(w http.ResponseWriter, status int, body string)

WriteTextResponse writes body with code status to w. The body will be interpreted as plain text.

Types

type Address 

type Address struct {
	Original, Scheme, Host, Port, Path string
}

Address represents a site address. It contains the original input value, and the component parts of an address. The component parts may be updated to the correct values as setup proceeds, but the original value should never be changed.

func (a Address) String() string

String returns a human-friendly print of the address.

func (Address) VHost 

func (a Address) VHost() string

func (Context) URI 

func (c Context) URI() string

URI returns the raw, unprocessed request URI (including query string and hash) obtained directly from the Request-Line of the HTTP request.

type Handler 

type Handler interface {
	ServeHTTP(http.ResponseWriter, *http.Request) (int, error)
}

Handler is like http.Handler except ServeHTTP may return a status code and/or error.

If ServeHTTP writes the response header, it should return a status code of 0. This signals to other handlers before it that the response is already handled, and that they should not write to it also. Keep in mind that writing to the response body writes the header, too.

If ServeHTTP encounters an error, it should return the error value so it can be logged by designated error-handling middleware.

If writing a response after calling the next ServeHTTP method, the returned status code SHOULD be used when writing the response.

If handling errors after calling the next ServeHTTP method, the returned error value SHOULD be logged or handled accordingly.

Otherwise, return values should be propagated down the middleware chain by returning them unchanged.

type HandlerConfig 

type HandlerConfig interface {
	RequestMatcher
	BasePath() string
}

HandlerConfig is a middleware configuration. This makes it possible for middlewares to have a common configuration interface.

TODO The long term plan is to get all middleware implement this interface for configurations.

type HandlerFunc 

type HandlerFunc func(http.ResponseWriter, *http.Request) (int, error)

HandlerFunc is a convenience type like http.HandlerFunc, except ServeHTTP returns a status code and an error. See Handler documentation for more information.

func (HandlerFunc) ServeHTTP 

func (f HandlerFunc) ServeHTTP(w http.ResponseWriter, r *http.Request) (int, error)

ServeHTTP implements the Handler interface.

type IfMatcher 

type IfMatcher struct {
	// contains filtered or unexported fields
}

IfMatcher is a RequestMatcher for 'if' conditions.

func (IfMatcher) And 

func (m IfMatcher) And(r *http.Request) bool

And returns true if all conditions in m are true.

func (IfMatcher) Match 

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

Match satisfies RequestMatcher interface. It returns true if the conditions in m are true.

func (IfMatcher) Or 

func (m IfMatcher) Or(r *http.Request) bool

Or returns true if any of the conditions in m is true.

type ListenerMiddleware added in v0.10.0 

type ListenerMiddleware func(caddy.Listener) caddy.Listener

ListenerMiddleware is similar to the Middleware type, except it chains one net.Listener to the next.

type LogRoller 

type LogRoller struct {
	Filename   string
	MaxSize    int
	MaxAge     int
	MaxBackups int
	LocalTime  bool
}

LogRoller implements a type that provides a rolling logger.

func DefaultLogRoller added in v0.10.0 

func DefaultLogRoller() *LogRoller

DefaultLogRoller will roll logs by default.

func (LogRoller) GetLogWriter 

func (l LogRoller) GetLogWriter() io.Writer

GetLogWriter returns an io.Writer that writes to a rolling logger. This should be called only from the main goroutine (like during server setup) because this method is not thread-safe; it is careful to create only one log writer per log file, even if the log file is shared by different sites or middlewares. This ensures that rolling is synchronized, since a process (or multiple processes) should not create more than one roller on the same file at the same time. See issue #1363.

type Logger added in v0.10.0 

type Logger struct {
	Output string
	*log.Logger
	Roller *LogRoller
	// contains filtered or unexported fields
}

Logger is shared between errors and log plugins and supports both logging to a file (with an optional file roller), local and remote syslog servers.

func NewTestLogger added in v0.10.0 

func NewTestLogger(buffer *bytes.Buffer) *Logger

NewTestLogger creates logger suitable for testing purposes

func (*Logger) Attach added in v0.10.0

type NonCloseNotifierError struct {
	// underlying type which doesn't implement CloseNotify
	Underlying interface{}
}

func (NonFlusherError) Error added in v0.9.4 

func (f NonFlusherError) Error() string

Implement Error

type NonHijackerError added in v0.9.4

func (NonHijackerError) Error added in v0.9.4 

func (h NonHijackerError) Error() string

Implement Error

type NonPusherError added in v0.10.1

	Underlying interface{}
}

NonPusherError is more descriptive error caused by a non pusher

func (NonPusherError) Error added in v0.10.1 

func (c NonPusherError) Error() string

Implement Error

type Path 

type Path string

Path represents a URI path.

func (Path) Matches 

func (p Path) Matches(other string) bool

Matches checks to see if other matches p.

Path matching will probably not always be a direct comparison; this method assures that paths can be easily and consistently matched.

type PathLimit added in v0.9.4 

type PathLimit struct {
	Path  string
	Limit int64
}

PathLimit is a mapping from a site's path to its corresponding maximum request body size (in bytes)

type Replacer 

type Replacer interface {
	Replace(string) string
	Set(key, value string)
}

Replacer is a type which can replace placeholder substrings in a string with actual values from a http.Request and ResponseRecorder. Always use NewReplacer to get one of these. Any placeholders made with Set() should overwrite existing values if the key is already used.

func NewReplacer 

func NewReplacer(r *http.Request, rr *ResponseRecorder, emptyValue string) Replacer

NewReplacer makes a new replacer based on r and rr which are used for request and response placeholders, respectively. Request placeholders are created immediately, whereas response placeholders are not created until Replace() is invoked. rr may be nil if it is not available. emptyValue should be the string that is used in place of empty string (can still be empty string).

type RequestMatcher 

type RequestMatcher interface {
	Match(r *http.Request) bool
}

RequestMatcher checks to see if current request should be handled by underlying handler.

func MergeRequestMatchers 

func MergeRequestMatchers(matchers ...RequestMatcher) RequestMatcher

MergeRequestMatchers merges multiple RequestMatchers into one. This allows a middleware to use multiple RequestMatchers.

func SetupIfMatcher 

func SetupIfMatcher(controller *caddy.Controller) (RequestMatcher, error)

SetupIfMatcher parses `if` or `if_op` in the current dispenser block. It returns a RequestMatcher and an error if any.

type ResponseRecorder 

type ResponseRecorder struct {
	http.ResponseWriter
	Replacer Replacer
	// contains filtered or unexported fields
}

ResponseRecorder is a type of http.ResponseWriter that captures the status code written to it and also the size of the body written in the response. A status code does not have to be written, however, in which case 200 must be assumed. It is best to have the constructor initialize this type with that default status code.

Setting the Replacer field allows middlewares to type-assert the http.ResponseWriter to ResponseRecorder and set their own placeholder values for logging utilities to use.

Beware when accessing the Replacer value; it may be nil!

func NewResponseRecorder 

func NewResponseRecorder(w http.ResponseWriter) *ResponseRecorder

NewResponseRecorder makes and returns a new responseRecorder, which captures the HTTP Status code from the ResponseWriter and also the length of the response body written through it. Because a status is not set unless WriteHeader is called explicitly, this constructor initializes with a status code of 200 to cover the default case.

func (*ResponseRecorder) CloseNotify 

func (r *ResponseRecorder) CloseNotify() <-chan bool

CloseNotify implements http.CloseNotifier. It just inherits the underlying ResponseWriter's CloseNotify method.

func (*ResponseRecorder) Flush 

func (r *ResponseRecorder) Flush()

Flush implements http.Flusher. It simply wraps the underlying ResponseWriter's Flush method if there is one, or does nothing.

func (*ResponseRecorder) Hijack 

func (r *ResponseRecorder) Hijack() (net.Conn, *bufio.ReadWriter, error)

Hijack implements http.Hijacker. It simply wraps the underlying ResponseWriter's Hijack method if there is one, or returns an error.

func (*ResponseRecorder) Push added in v0.10.0 

func (r *ResponseRecorder) Push(target string, opts *http.PushOptions) error

Push resource to client

func (*ResponseRecorder) Size 

func (r *ResponseRecorder) Size() int

Write is a wrapper that records the size of the body that gets written.

func (*ResponseRecorder) WriteHeader 

func (r *ResponseRecorder) WriteHeader(status int)

WriteHeader records the status code and calls the underlying ResponseWriter's WriteHeader method.

type Server 

type Server struct {
	Server *http.Server
	// contains filtered or unexported fields
}

Server is the HTTP server implementation.

func NewServer 

func NewServer(addr string, group []*SiteConfig) (*Server, error)

func (*Server) OnStartupComplete 

func (s *Server) OnStartupComplete()

OnStartupComplete lists the sites served by this server and any relevant information, assuming caddy.Quiet == false.

func (*Server) Serve 

func (s *Server) Serve(ln net.Listener) error

Serve serves requests on ln. It blocks until ln is closed.

func (*Server) ServeHTTP 

func (s *Server) ServeHTTP(w http.ResponseWriter, r *http.Request)

ServeHTTP is the entry point of all HTTP requests.

func (*Server) ServePacket 

func (s *Server) ServePacket(pc net.PacketConn) error

ServePacket serves QUIC requests on pc until it is closed.

func (*Server) Stop 

func (s *Server) Stop() error

Stop stops s gracefully (or forcefully after timeout) and closes its listener.

type SiteConfig 

type SiteConfig struct {
	// The address of the site
	Addr Address

	// The hostname to bind listener to;
	// defaults to Addr.Host
	ListenHost string

	// TLS configuration
	TLS *caddytls.Config

	// Directory from which to serve files
	Root string

	// A list of files to hide (for example, the
	// source Caddyfile). TODO: Enforcing this
	// should be centralized, for example, a
	// standardized way of loading files from disk
	// for a request.
	HiddenFiles []string

	// Max amount of bytes a request can send on a given path
	MaxRequestBodySizes []PathLimit

	// These timeout values are used, in conjunction with other
	// site configs on the same server instance, to set the
	// respective timeout values on the http.Server that
	// is created. Sensible values will mitigate slowloris
	// attacks and overcome faulty networks, while still
	// preserving functionality needed for proxying,
	// websockets, etc.
	Timeouts Timeouts
	// contains filtered or unexported fields
}

SiteConfig contains information about a site (also known as a virtual host).

func GetConfig 

func GetConfig(c *caddy.Controller) *SiteConfig

GetConfig gets the SiteConfig that corresponds to c. If none exist (should only happen in tests), then a new, empty one will be created.

func (*SiteConfig) AddListenerMiddleware added in v0.10.0 

func (s *SiteConfig) AddListenerMiddleware(l ListenerMiddleware)

AddListenerMiddleware adds a listener middleware to a site's listenerMiddleware stack.

	WriteTimeout         time.Duration
	WriteTimeoutSet      bool
	IdleTimeout          time.Duration
	IdleTimeoutSet       bool
}

Timeouts specify various timeouts for a server to use. If the assocated bool field is true, then the duration value should be treated literally (i.e. a zero-value duration would mean "no timeout"). If false, the duration was left unset, so a zero-value duration would mean to use a default value (even if default is non-zero).
