Types ¶
type DataRewriter ¶
type DataRewriter struct {
// Data maps conditions to rewrite units. Multiple fields can be matched in sequence to determine the rewrite rule.
// level 1: map[string] list of fields, multiple fields separated by DataConditionSep, each rewrite needs to match all the fields.
// level 2: map[string] Match condition, multiple fields separated by DataConditionSep.
// level 3: []RewriteUnit rewrite unit, rewrites sequentially, in the order it was loaded
Data map[string]map[string][]RewriteUnit
}
DataRewriter is responsible for rewriting data based on the provided rules. It uses predefined conditions to determine which data entries should be modified.
func NewDataRewriter ¶
func NewDataRewriter() *DataRewriter
NewDataRewriter initializes and returns a new DataRewriter.
func (*DataRewriter) Do ¶
func (d *DataRewriter) Do(info *model.IPInfo) error
Do applies the data rewriting rules to the provided IPInfo.
func (*DataRewriter) LoadFile ¶
func (d *DataRewriter) LoadFile(file string) error
LoadFile loads the rewriting rules from a file.
func (*DataRewriter) LoadFiles ¶
func (d *DataRewriter) LoadFiles(files []string) error
LoadFiles loads the rewriting rules from a list of files.
func (*DataRewriter) LoadString ¶
func (d *DataRewriter) LoadString(data ...string)
LoadString loads rewriting rules from the provided data strings.
type FieldSelector ¶
type FieldSelector struct {
// contains filtered or unexported fields
}
FieldSelector represents a selector that can be applied to IPInfo to select and modify fields.
func NewFieldSelector ¶
func NewFieldSelector(meta *model.Meta, arg string) (*FieldSelector, error)
NewFieldSelector initializes a FieldSelector based on the given argument string. It supports a custom string format to determine which fields to select and under which conditions. The format is: <fields>[|<rule1>:<fields>|<rule2>:<fields>|<default fields>] MAKE SURE that the incoming meta comes from StandardReader, not DB Reader, since it may modify the *model.Meta. Refer to the provided examples in the function comments for more details.
func (*FieldSelector) Do ¶
func (f *FieldSelector) Do(info *model.IPInfo) error
Do applies the field selector rules to an IPInfo object, selecting and modifying fields as necessary.
func (*FieldSelector) Fields ¶
func (f *FieldSelector) Fields() []string
Fields returns the list of fields currently set in the field selector.
type FieldSelectorRule ¶
type FieldSelectorRule struct {
Condition url.Values
Fields []string
ReplaceFields map[string]string
}
FieldSelectorRule represents a single rule within a FieldSelector.
type IPOperateChain ¶
type IPOperateChain struct {
// contains filtered or unexported fields
}
IPOperateChain represents a chain of IPOperateFuncs, organized to be executed in the order they are added.
func NewIPOperateChain ¶
func NewIPOperateChain() *IPOperateChain
NewIPOperateChain initializes and returns a new IPOperateChain.
func (*IPOperateChain) Do ¶
func (c *IPOperateChain) Do(info *model.IPInfo) error
Do executes all the operations in the chain on the given IPInfo.
func (*IPOperateChain) Use ¶
func (c *IPOperateChain) Use(f IPOperateFunc)
Use adds an IPOperateFunc to the end of the operation chain.
type IPOperateFunc ¶
IPOperateFunc defines a function type for operations on IPInfo, such as filtering fields, rewriting data, supplementing data, etc.
type RewriteUnit ¶
type RewriteUnit struct {
Condition url.Values // Condition to match for rewriting
Replace url.Values // Content to replace if the condition is matched
}
RewriteUnit is a structure that holds the condition to match and the content to replace.
type Translator ¶ added in v0.2.1
type Translator struct {
TargetLang string // Target language for translation
}
Translator is a structure that provides functionality to translate IPInfo's geolocation fields.
func NewTranslator ¶ added in v0.2.1
func NewTranslator(targetLang string) (*Translator, error)
NewTranslator initializes a new Translator for a given target language.
