Description
Technical Field
The application relates to the technical field of internet, in particular to a website access method and device.
Background
Currently, the DNS (Domain Name System) is a distributed database on the internet as a mapping between Domain names and IP addresses, which enables users to access the internet more conveniently without remembering IP strings that can be read directly by machines. At present, the steps of analyzing a domain name port and a domain name protocol type of a target website are added on the basis of original domain name IP address analysis through expansion of a DNS protocol network, so that the site freely configures the protocol and the port, the operation steps of webpage access are simplified, and the safety of webpage access is improved. However, since the extended DNS protocol is not commonly used, the mainstream network tools communicate according to the existing network protocol. Although the network tool aiming at the HTTP protocol can redirect the subsequent access of the HTTP network tool according to the domain name port and the domain name protocol type returned by the DNS protocol, so that the HTTP network tool can be normally used. But for other network tools without redirection function (e.g. protocols such as FTP), the above scheme cannot be used.

However, since the extended DNS protocol is not commonly used, the mainstream network tools communicate according to the existing network protocol. Although the network tool aiming at the HTTP protocol can redirect the subsequent access of the HTTP network tool according to the domain name port and the domain name protocol type returned by the DNS protocol, so that the HTTP network tool can be normally used. But for other network tools without redirection function (e.g. protocols such as FTP), the above scheme cannot be used.
Based on the above technical problem, the present inventors propose the following technical solution to solve or improve the above problem. It should be noted that the above prior art solutions have shortcomings, which are the results of practical and careful study by the inventor, and therefore, the discovery process of the above problems and the solutions proposed by the following embodiments of the present application for the above problems should be the contribution of the inventor to the present application in the process of the present application.
Fig. 2 is a flowchart illustrating a website access method provided in some embodiments of the present application, which may be performed by the website access system 10 shown in fig. 1. It should be understood that, in other embodiments, the order of some steps in the website access method of this embodiment may be interchanged according to actual needs, or some steps may be omitted or deleted. The detailed steps of the website access method are described as follows.
Step S110, the user terminal 100 calls the callable function to input the target domain name into the entry parameter information according to the target domain name generated by the network access tool, and sends a DNS request packet to the DNS server 200 according to the target domain name in the entry parameter information.
In this embodiment, the user terminal 100 may be installed with network access tools of various network protocols, such as a network access tool of HTTP (HTTP, HyperText Transfer Protocol), HTTPs (HyperText Transfer Protocol over Secure Socket Layer or HyperText Transfer Protocol Secure, HyperText Transfer security Protocol), FTP (File Transfer Protocol), SMTP (Simple Mail Transfer Protocol).
In order to enable each network access tool to be capable of adapting to the extended DNS protocol network, in this embodiment, a static data connection library lib file may be configured in each network access tool, and various callable functions and parameter information called by the callable functions may be stored in the lib file. On this basis, when any network access tool on the user terminal 100 generates a DNS query request to query the DNS, the callable function in the lib file of the static data connection library may be called to obtain the target domain name from the DNS query request, and a DNS request packet is sent to the DNS server 200 according to the target domain name.
It should be noted that, in other embodiments, the above-mentioned static data link library lib file may also be replaced by other callable programs, only that the callable program can provide the input function of the target domain name and the output function of the domain name data.
Step S120, the DNS server 200 searches for domain name data corresponding to the target domain name according to the DNS request packet, and sends the domain name data to the user terminal 100.
As an implementation manner, the DNS server 200 may store domain name data corresponding to domain names of various websites in advance, where the domain name data includes a domain name IP address, or a domain name IP address, a domain name port, and a domain name protocol. For example, when each website domain name is registered, the corresponding website server sends a registration request to the DNS server 200, the DNS server 200 records domain name data of each website domain name in response to the registration request, and for a general DNS protocol, the domain name data may only include a domain name IP address. For the extended DNS protocol, the domain name data may include domain name IP addresses, domain name ports, and domain name protocols.
On the basis, the DNS server 200 may obtain the target domain name by analyzing the DNS request message sent by the user terminal 100, and then search the domain name data corresponding to the target domain name from the domain name data corresponding to the domain names of the respective websites.
Step S130, the user terminal 100 receives the domain name data through the callable function, and returns the domain name data as parameter information to the network access tool.
In detail, if the domain name data includes domain name port information and domain name protocol information, returning the domain name data to the network access tool, and executing:
step S140, if the domain name data includes a domain name port and a domain name protocol, determining, by the network access tool, whether the domain name port and the domain name protocol in the domain name data are respectively the same as a domain name port and a domain name protocol recorded in advance, and determining whether the domain name protocol in the domain name data is a protocol supported by the network access tool.
In detail, if a domain name port and a domain name protocol in the domain name data are respectively the same as a domain name port and a domain name protocol recorded in advance, and the domain name protocol in the domain name data is a protocol supported by the network access tool, then:
step S150, sending a website access request to a corresponding website server according to the domain name data, so that the website server returns corresponding website contents, such as pictures, characters, audio, video, and the like, in response to the website access request.
In another case, if the domain name data does not include domain name port information and domain name protocol information, performing:
step S160, sending a website access request to a corresponding website server according to the domain name IP address in the domain name data, so that the website server returns corresponding website content in response to the website access request.
In addition, if the domain name port and the domain name protocol in the domain name data are different from the domain name port and the domain name protocol which are recorded in advance, prompt information for changing the domain name port and the domain name protocol which are recorded in advance into the domain name port and the domain name protocol in the domain name data is output, or the domain name port and the domain name protocol in the domain name data are changed into the domain name port and the domain name protocol in the domain name data through the callable function.
The domain name port recorded in advance may refer to a domain name port selected by a user when inputting a website domain name, for example, if the selected domain name port is an 80 port, but actually, if the selected domain name port is a 90 port of the domain name port in the domain name data, the user is prompted to change the 80 port to the 90 port, or the 80 port is automatically changed to the 90 port through the callable function.
Or if the domain name protocol in the domain name data is not the protocol supported by the network access tool, outputting prompt information which does not support the domain name protocol in the domain name data.
Based on the above design, the website access method provided in this embodiment modifies the network access tool of the existing user terminal 100, and pre-configures the static data link library lib file in the network access tool, so that during network access, an adjustable function in the static data link library lib file configured in the network access tool can be called to obtain a target domain name and obtain corresponding domain name data from the DNS server 200 according to the target domain name, and then network access of the target domain name is performed according to the domain name data. Therefore, network access tools of various network protocol types for configuring the static data connection library lib file can adapt to the extended DNS protocol, so that the site can freely configure the protocol and the port, and the operation steps of webpage access are simplified.
Further, referring to fig. 3, an embodiment of the present application further provides a website access method, which is different from the above embodiment, that the website access method is executed by the user terminal 100, it is understood that steps involved in the website access method to be described next have been described in the above embodiment, and specific details of each step may be described with reference to the above embodiment, and only the steps executed by the user terminal 100 will be briefly described below.
Step S210, according to the target domain name generated by the network access tool, invoking the callable function to input the target domain name into the entry parameter information.
Step S220, sending a DNS request packet to the DNS server 200 according to the target domain name in the entry parameter information, so that the DNS server 200 searches, according to the DNS request packet, domain name data corresponding to the target domain name, where the domain name data at least includes a domain name IP address.
Step S230, receiving the domain name data through the callable function, and returning the domain name data as parameter information to the network access tool.
Step S240, if the domain name data includes a domain name port and a domain name protocol, determining, by the network access tool, whether the domain name port and the domain name protocol in the domain name data are respectively the same as a domain name port and a domain name protocol recorded in advance, and determining whether the domain name protocol in the domain name data is a protocol supported by the network access tool.
Step S250, if the domain name port and the domain name protocol in the domain name data are respectively the same as the domain name port and the domain name protocol recorded in advance, and the domain name protocol in the domain name data is a protocol supported by the network access tool, sending a website access request to a corresponding website server according to the domain name data, so that the website server responds to the website access request and returns corresponding website content.
In a possible implementation manner, if the domain name data does not include domain name port information and domain name protocol information, a website access request is sent to a corresponding website server according to a domain name IP address in the domain name data, so that the website server returns corresponding website content in response to the website access request.
In a possible implementation manner, if the domain name port and the domain name protocol in the domain name data are different from the domain name port and the domain name protocol recorded in advance, prompt information for changing the domain name port and the domain name protocol recorded in advance into the domain name port and the domain name protocol in the domain name data is output, or the domain name port recorded in advance is changed into the domain name port and the domain name protocol in the domain name data through the callable function.
In a possible implementation manner, if the domain name protocol in the domain name data is not a protocol supported by the network access tool, the prompt message that the domain name protocol in the domain name data is not supported is output.
