Functions ¶
func GetMatcherFactories ¶
func GetMatcherFactories() map[string]func() ConditionMatcherFactory
GetMatcherFactories gets all create matcherFactory function
func GetSampleValueFromURL ¶
func GetSampleValueFromURL(conditionKey string, sample map[string]string, param *common.URL, invocation protocol.Invocation) string
GetSampleValueFromURL returns the value of the conditionKey in the URL
func SetMatcherFactory ¶
func SetMatcherFactory(name string, fun func() ConditionMatcherFactory)

Types ¶
type ArgumentConditionMatcher ¶
type ArgumentConditionMatcher struct {
BaseConditionMatcher
}
ArgumentConditionMatcher analysis the arguments in the rule. Examples would be like this: "arguments[0]=1", whenCondition is that the first argument is equal to '1'. "arguments[1]=a", whenCondition is that the second argument is equal to 'a'.
func NewArgumentConditionMatcher ¶
func NewArgumentConditionMatcher(key string) *ArgumentConditionMatcher
func (*ArgumentConditionMatcher) GetValue ¶
func (a *ArgumentConditionMatcher) GetValue(sample map[string]string, url *common.URL, invocation protocol.Invocation) string
type ArgumentMatcherFactory ¶
type ArgumentMatcherFactory struct {
}
ArgumentMatcherFactory matcher factory
func (*ArgumentMatcherFactory) NewMatcher ¶
func (a *ArgumentMatcherFactory) NewMatcher(key string) Matcher
NewMatcher constructs a new matcher
func (*ArgumentMatcherFactory) Priority ¶
func (a *ArgumentMatcherFactory) Priority() int64
func (*ArgumentMatcherFactory) ShouldMatch ¶
func (a *ArgumentMatcherFactory) ShouldMatch(key string) bool
type AttachmentConditionMatcher ¶
type AttachmentConditionMatcher struct {
BaseConditionMatcher
}
AttachmentConditionMatcher analysis the attachments in the rule. Examples would be like this: "attachments[version]=1.0.0&attachments[timeout]=1000", whenCondition is that the version is equal to '1.0.0' and the timeout is equal to '1000'.
func NewAttachmentConditionMatcher ¶
func NewAttachmentConditionMatcher(key string) *AttachmentConditionMatcher
func (*AttachmentConditionMatcher) GetValue ¶
func (a *AttachmentConditionMatcher) GetValue(sample map[string]string, url *common.URL, invocation protocol.Invocation) string
type AttachmentMatcherFactory ¶
type AttachmentMatcherFactory struct {
}
AttachmentMatcherFactory matcher factory
func (*AttachmentMatcherFactory) NewMatcher ¶
func (a *AttachmentMatcherFactory) NewMatcher(key string) Matcher
NewMatcher constructs a new matcher
func (*AttachmentMatcherFactory) Priority ¶
func (a *AttachmentMatcherFactory) Priority() int64
func (*AttachmentMatcherFactory) ShouldMatch ¶
func (a *AttachmentMatcherFactory) ShouldMatch(key string) bool
type BaseConditionMatcher ¶
type BaseConditionMatcher struct {
// contains filtered or unexported fields
}
BaseConditionMatcher records the match and mismatch patterns of this matcher while at the same time provides the common match logics.
func NewBaseConditionMatcher ¶
func NewBaseConditionMatcher(key string) *BaseConditionMatcher
func (*BaseConditionMatcher) GetMatches ¶
func (b *BaseConditionMatcher) GetMatches() map[string]struct{}
GetMatches returns matches.
func (*BaseConditionMatcher) GetMismatches ¶
func (b *BaseConditionMatcher) GetMismatches() map[string]struct{}
GetMismatches returns misMatches.
func (*BaseConditionMatcher) GetValue ¶
func (b *BaseConditionMatcher) GetValue(sample map[string]string, url *common.URL, invocation protocol.Invocation) string
GetValue returns a value from different places of the request context.
func (*BaseConditionMatcher) IsMatch ¶
func (b *BaseConditionMatcher) IsMatch(value string, param *common.URL, invocation protocol.Invocation, isWhenCondition bool) bool
IsMatch indicates whether this matcher matches the patterns with request context.
type ConditionMatcherFactory ¶
type ConditionMatcherFactory interface {
// ShouldMatch indicates whether the key is of the form of the current matcher type which this factory instance represents.
ShouldMatch(key string) bool
// NewMatcher returns a matcher instance for the key.
NewMatcher(key string) Matcher
// Priority returns Priority in ConditionMatcherFactory
// 0 to ^int(0) is better, smaller value by better priority.
Priority() int64
}
func GetMatcherFactory ¶
func GetMatcherFactory(name string) ConditionMatcherFactory
GetMatcherFactory gets create matcherFactory function by name
func NewArgumentMatcherFactory ¶
func NewArgumentMatcherFactory() ConditionMatcherFactory
NewArgumentMatcherFactory constructs a new argument.ArgumentMatcherFactory
func NewAttachmentMatcherFactory ¶
func NewAttachmentMatcherFactory() ConditionMatcherFactory
NewAttachmentMatcherFactory constructs a new attachment.AttachmentMatcherFactory
func NewParamMatcherFactory ¶
func NewParamMatcherFactory() ConditionMatcherFactory
NewParamMatcherFactory constructs a new paramMatcherFactory
type Matcher ¶
type Matcher interface {
// IsMatch indicates whether this matcher matches the patterns with request context.
IsMatch(value string, param *common.URL, invocation protocol.Invocation, isWhenCondition bool) bool
// GetMatches returns matches.
// match patterns extracted from when condition.
GetMatches() map[string]struct{}
// GetMismatches returns misMatches.
// mismatch patterns extracted from then condition.
GetMismatches() map[string]struct{}
// GetValue returns a value from different places of the request context, for example, url, attachment and invocation.
// This makes condition rule possible to check values in any place of a request.
GetValue(sample map[string]string, url *common.URL, invocation protocol.Invocation) string
}
Matcher represents a specific match condition of a condition rule. The following condition rule 'foo=bar&arguments[0]=hello* => region=hangzhou' consists of three ConditionMatchers: 1. ParamConditionMatcher represented by 'foo=bar' 2. ArgumentConditionMatcher represented by 'arguments[0]=hello*' 3. ParamConditionMatcher represented by 'region=hangzhou'
type ParamConditionMatcher ¶
type ParamConditionMatcher struct {
BaseConditionMatcher
}
func NewParamConditionMatcher ¶
func NewParamConditionMatcher(key string) *ParamConditionMatcher
func (*ParamConditionMatcher) GetValue ¶
func (p *ParamConditionMatcher) GetValue(sample map[string]string, url *common.URL, invocation protocol.Invocation) string
type ParamMatcherFactory ¶
type ParamMatcherFactory struct {
}

func (*ParamMatcherFactory) NewMatcher ¶
func (p *ParamMatcherFactory) NewMatcher(key string) Matcher
NewMatcher constructs a new matcher
func (*ParamMatcherFactory) Priority ¶
func (p *ParamMatcherFactory) Priority() int64
Priority make sure this is the last matcher being executed. This instance will be loaded separately to ensure it always gets executed as the last matcher.
func (*ParamMatcherFactory) ShouldMatch ¶
func (p *ParamMatcherFactory) ShouldMatch(key string) bool
