Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] The process of URL parsing is to gradually decompose the domains of the URL according to the delimiters between the domains specified in the URL syntax during the process of scanning the URL. Therefore, it is necessary to know the domains of the URL, the character sets allowed by each domain, the separators of each domain and the reserved characters that are allowed to exist in the form of non-separators. The URL consists of a series of characters in th...

Abstract

The embodiment of the invention provides URL (Uniform Resource Location) analyzing method and equipment. The method comprises the steps of: scanning characters in a URL character string sequentially; updating the current state of an FSM (FDM-channel Selector Module) according to the scanned current character, a constructed FSM state conversion table of the URL and the current state of the FSM; updating the state of a sub FSM according to the scanned current character, a sub FSM state conversion table of constructing a path field and the current state of the sub FSM when scanning the characters of the path field of the URL, wherein the sub FSM state conversion table comprises the states of the updated sub FSMs corresponding to different types of characters when different types of characters are scanned in the current states of different sub FSMs; when the final states of the FSM and the sub FSMs are accepting states, judging that the URL conforms to URL syntax; otherwise, judging that the URL does not conform to the URL syntax.

Description

technical field [0001] The invention relates to the technical fields of computer and communication, in particular to a method and device for analyzing URLs. Background technique [0002] A uniform resource locator (Uniform Resource Locator, URL for short) is a standard resource address on the Internet, which is used to completely describe web pages and other resources on the Internet, and can also identify local resources. A URL can uniquely identify every web page or resource on the Internet. The URL consists of a series of characters in the format: protocol: / / [username:password]@host[:port][ / path][? query][#fragment]. Among them, the protocol field specifies the transmission protocol, such as: HTTP protocol, FTP protocol, etc.; the host field specifies the host name or IP address of the server storing resources; the username and password fields specify the user name and password required to connect to the server; the port field specifies the above The port number of the...
