Form_urlencoded Parser¶

The Form_urlencoded parser is used for working with the request body in the form-urlencoded format. This parser creates a hash table where the names of the request body parameters are the keys and the values of the corresponding parameters are the hash table values. The elements of this hash table need to be referred to by using the names of the parameters.

Regular expressions in points

The parameter name in the point can be a regular expression of the Ruby programming language.

Using the Form_urlencoded parser in the point

The Form_urlencoded parser can only be used in the point together with the Post filter that refers to the baseline request body.

The request body in the form-urlencoded format may also contain the following complex data structures: arrays and hash tables. Use the Array and Hash filters correspondingly to address the elements in these structures.

Example:

For the

POST http://example.com/login/index.php HTTP/1.1
Content-Type: application/x-www-form-urlencoded

request with the

id=01234&username=John

body, the Form_urlencoded parser applied to the request body creates the following hash table:

Key	Value
id	01234
username	John

The POST_FORM_URLENCODED_id_value point refers to the 01234 value that corresponds to the id key from the hash table created by the Form_urlencoded parser.
The POST_FORM_URLENCODED_username_value point refers to the John value that corresponds to the username key from the hash table created by the Form_urlencoded parser.
