type Location ¶

type Location struct {
	Seq        int              // 定义的顺序
	Priority   ModifierPriority // 匹配级别，从0开始，数字越小，匹配优先级越高
	Modifier   Modifier
	Path       string
	Processors Processors
	Pattern    *regexp.Regexp
}

Location is the location.

func (l Location) Matches(p ModifierPriority, r *http.Request) bool

func (l *Location) Parse(directive string, params []string) bool

func (l Location) ServeHTTP(w http.ResponseWriter, r *http.Request)

type Locations ¶

type Locations []Location

func (ls Locations) FindLocation(r *http.Request) *Location

func (ls Locations) Len() int

func (ls Locations) Less(i, j int) bool

func (ls Locations) Swap(i, j int)

type Modifier ¶

type Modifier string

Modifier is the location modifier.

func (m Modifier) Priority() ModifierPriority

type ModifierPriority ¶

type ModifierPriority int

ModifierPriority defines the priority of the modifier. https://end0tknr.wordpress.com/2015/12/22/location-match-priority-in-nginx/. https://artfulrobot.uk/blog/untangling-nginx-location-block-matching-algorithm. https://blog.csdn.net/qq_15766181/article/details/72829672. priority | prefix | example. 1 | = (exactly) | location = /path. 2 | ^~ (forward match) | location = /image. 3 | ~ or ~* (regular & case-(in)sensitive) | location ~ /image/. 4 | NONE (forward match) | location /image.

const (
	// ModifierExactly like location = /path matches the query / only.
	ModifierExactly ModifierPriority = iota + 1
	// ModifierForward like location ^~ /path.
	// matches any query beginning with /path/ and halts searching,
	// so regular expressions will not be checked.
	ModifierForward
	// ModifierRegular like location ~ \.(gif|jpg|jpeg)$
	// or like location ~* .(jpg|png|bmp).
	ModifierRegular
	// ModifierNone means none modifier for the location.
	ModifierNone
)

type Processor interface {
	Naming
	GetProcessSeq() ProcessSeq
	Parse(path string, name string, params []string) error
	Do(l Location, w http.ResponseWriter, r *http.Request) ProcessResult
}
