A method of accessing from public web site to intranet database

Abstract

The invention discloses an access method from a public network WEB (World Wide Web) to an intranet database. The method comprises the following steps of setting a database query program, a database executing program and a first buffer area in a public network, setting a permanent client program and a second buffer area in an intranet, wherein a HASH table is arranged in the first buffer area, initiating a request by the intranet to the public network for continuously opening a webpage of the public network, so as to download and upload data. The access method provided by the invention has the advantages that the method provided by the invention can be used for replacing the original public network to initiate a request to the intranet, in such a way, a WEB server of the public network does not actively initiate a connection to the intranet, the firewall allows such situation for the situation is very safe; in the method, an enterprise WEB website in the public network can access the data of the intranet real-time without establishing a database; and moreover, the field and read-write permissions of the data can be predefined; and meanwhile, the intranet can be provided with a full firewall, so as to forbid the public network to access the intranet, and the access of the public network to the intranet data is not influenced.

Description

technical field [0001] The invention relates to an access method of a website database, in particular to an access method from a public network WEB website to an intranet database. Background technique [0002] At present, many enterprise users who have established enterprise intranets and databases cannot publish WEB websites in their own intranet servers because they do not have a fixed public network (INTERNET network) IP address or for security reasons. Such enterprises generally use hosting, virtual hosting, etc. to build their own WEB websites. Since the WEB website is established in the public network, if the data in the intranet database established by the enterprise is to be published on the WEB, the WEB server of the public network either needs to access the intranet of the enterprise, or the intranet of the enterprise regularly communicates with the website located in the public network. The database is synchronized. Generally speaking, users of the former need ...

AI Technical Summary

Problems solved by technology

Generally speaking, users of the former need a fixed public network IP address to map to the intranet server, and there are serious risks such as malicious access to the intranet; while the latter not only has difficulty in ensuring real-time performance, but also has problems because the data is stored on the public network. Security issues such as malicious tampering due to storage

At present, most small and medium-sized enterprises use virtual hosts and host hosting methods to establish WEB sites on the public network, and most of their intranets are equipped with firewalls, so the WEB servers on the public network cannot access their intranets, and ordinary WEB web page programs cannot directly access the internal network. network database, so its public network website cannot achieve real-time synchronization with enterprise intranet data
