Problems solved by technology

[0003] However, the above-mentioned technology of picking out domain names served by non-http80 port through crawler program, when the page is not pulled by the page, but directly accessed through browser input, and the accessible content of the page is not under the root domain name, it is The required non-http80 port domain name cannot be fetched through the crawler program, resulting in a technical problem of cache error
[0004] Therefore, in order to improve the technical defect that the crawler program cannot retrieve the required domain name with port other than http80 in some scenarios, those skilled in the art urgently need to solve the aforementioned technical problems

Embodiment Construction

[0057] Embodiments of the present invention provide a method and device for organizing Internet ports, which are used to improve the technical defect that the existing crawler program cannot retrieve the required domain name of the non-http80 port in some scenarios.

[0058] HTTP (Hypertext transfer protocol, Hypertext Transfer Protocol), is a data transfer protocol that specifies the rules for mutual communication between browsers and World Wide Web servers, and transmits World Wide Web documents through the Internet.

[0059] NAT (Network Address Translation, Network Address Translation) is the process of converting the IP address in the IP packet header to another IP address. In practical applications, NAT is mainly used to enable private networks to access public networks. This approach of using a small number of public IP addresses to represent a large number of private IP addresses will help slow the depletion of available IP address space.

[0060] In order to make the...

Abstract

The embodiment of the invention discloses a method and device for disposing Internet ports. The technical shortcoming that an existing crawler procedure cannot get out domain names of the needed non-http80 ports under certain occasions is overcome. The method includes the steps of obtaining the domain names and ip addresses corresponding to the domain names, building transfer ip addresses corresponding to the domain names, analyzing the domain names in a grouping mode into the transfer ip addresses in a redirection mode, sequentially analyzing the ports of the domain names, and extracting the domain names corresponding to the non-http80 ports.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for organizing Internet ports. Background technique [0002] The use of Internet-based service ports is not uniform and non-standard. Programmers often use unconventional port 80 as http service ports, such as: 8080, 8090 and other ports, and in order to improve the security of user data when visiting users log in to the website, SSL data encrypted transmission using https, a considerable number of websites will choose to use http and https protocols under the same domain name, etc. Based on the cache caching technology in these two Internet technologies, crawlers are usually used to search Internet pages Crawl, and then take out the target in the page, and pick out the domain name served by the non-http80 port by judging the protocol and the port behind the domain name. [0003] However, the above-mentioned technology of picking out domain names served ...
