Types

type Extractor

type Extractor struct {
	// description: |
	//   Name of the extractor. Name should be lowercase and must not contain
	//   spaces or underscores (_).
	// examples:
	//   - value: "\"cookie-extractor\""
	Name string `yaml:"name,omitempty" json:"name,omitempty" jsonschema:"title=name of the extractor,description=Name of the extractor"`
	// description: |
	//   Type is the type of the extractor.
	Type ExtractorTypeHolder `json:"type" yaml:"type"`

	// description: |
	//   Regex contains the regular expression patterns to extract from a part.
	//
	//   Go regex engine does not support lookaheads or lookbehinds, so as a result
	//   they are also not supported in nuclei.
	// examples:
	//   - name: Braintree Access Token Regex
	//     value: >
	//       []string{"access_token\\$production\\$[0-9a-z]{16}\\$[0-9a-f]{32}"}
	//   - name: Wordpress Author Extraction regex
	//     value: >
	//       []string{"Author:(?:[A-Za-z0-9 -\\_=\"]+)?<span(?:[A-Za-z0-9 -\\_=\"]+)?>([A-Za-z0-9]+)<\\/span>"}
	Regex []string `` /* 130-byte string literal not displayed */
	// description: |
	//   Group specifies a numbered group to extract from the regex.
	// examples:
	//   - name: Example Regex Group
	//     value: "1"
	RegexGroup int `` /* 132-byte string literal not displayed */

	// description: |
	//   kval contains the key-value pairs present in the HTTP response header.
	//   kval extractor can be used to extract HTTP response header and cookie key-value pairs.
	//   kval extractor inputs are case-insensitive, and does not support dash (-) in input which can replaced with underscores (_)
	// 	 For example, Content-Type should be replaced with content_type
	//
	//   A list of supported parts is available in docs for request types.
	// examples:
	//   - name: Extract Server Header From HTTP Response
	//     value: >
	//       []string{"server"}
	//   - name: Extracting value of PHPSESSID Cookie
	//     value: >
	//       []string{"phpsessid"}
	//   - name: Extracting value of Content-Type Cookie
	//     value: >
	//       []string{"content_type"}
	KVal []string `` /* 146-byte string literal not displayed */

	// description: |
	//   JSON allows using jq-style syntax to extract items from json response
	//
	// examples:
	//   - value: >
	//       []string{".[] | .id"}
	//   - value: >
	//       []string{".batters | .batter | .[] | .id"}
	JSON []string `` /* 161-byte string literal not displayed */
	// description: |
	//   XPath allows using xpath expressions to extract items from html response
	//
	// examples:
	//   - value: >
	//       []string{"/html/body/div/p[2]/a"}
	XPath []string `` /* 188-byte string literal not displayed */
	// description: |
	//   Attribute is an optional attribute to extract from response XPath.
	//
	// examples:
	//   - value: "\"href\""
	Attribute string `` /* 175-byte string literal not displayed */

	// description: |
	//   Extracts using DSL expressions.
	DSL []string `` /* 147-byte string literal not displayed */

	// description: |
	//   Part is the part of the request response to extract data from.
	//
	//   Each protocol exposes a lot of different parts which are well
	//   documented in docs for each request type.
	// examples:
	//   - value: "\"body\""
	//   - value: "\"raw\""
	Part string `` /* 162-byte string literal not displayed */
	// description: |
	//   Internal, when set to true will allow using the value extracted
	//   in the next request for some protocols (like HTTP).
	Internal bool `` /* 231-byte string literal not displayed */

	// description: |
	//   CaseInsensitive enables case-insensitive extractions. Default is false.
	// values:
	//   - false
	//   - true
	CaseInsensitive bool `` /* 156-byte string literal not displayed */
	// contains filtered or unexported fields
}
