Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
Fig. 1 is a schematic flowchart of a domain name service resource access method provided by an embodiment of the present disclosure. The embodiment is applicable to the case of domain name service resource access based on a Virtual Private Network (VPN) client. The method of the embodiment may be performed by a domain name service resource access device, which may be implemented in hardware and/or software and may be configured in an electronic device. As shown in fig. 1, the method specifically includes the following steps:
s110, obtaining domain names corresponding to a plurality of domain name service resources corresponding to the virtual private network VPN client.
Among them, the VPN client can be understood as: a device for establishing a VPN connection for a user to thereby implement a corresponding domain name service resource access; the VPN client may include a Secure socket virtual Private Network (SSL VPN) client, and SSL VPN may be understood as a VPN technology that uses SSL protocol to implement remote access. SSL is understood as a set of network data security protocols that can be widely used for authentication and encrypted data transmission between a browser and a server. The SSL Protocol is located between a Transmission Control Protocol/Internet Protocol (TCP/IP) and various application layer protocols, and provides security support for data communication. The SSL protocol can be divided into two layers: the SSL recording Protocol (SSL Record Protocol) is established on a reliable transmission Protocol (such as TCP) and provides support for basic functions of data encapsulation, compression, encryption and the like for a higher-layer Protocol; the SSL Handshake Protocol (SSL Handshake Protocol) is established on the SSL recording Protocol, and is used for performing identity authentication, negotiating an encryption algorithm, exchanging an encryption key, and the like on both communication sides before actual data transmission starts. The user can input login information, such as a login account name and an account password, on the VPN client, so as to log in an account of the user to access the service resource. The domain name service resource can be understood as a specified service bound with the user and capable of being accessed by the user after logging in the VPN client. A Domain Name (Domain Name), also called web Domain, is understood to be the Name of a computer or a group of computers on the Internet (network) composed of a string of names separated by points, which is used to identify the computer location during data transmission, for example, the web address used by the user during web browsing.
Since domain name service resources corresponding to different VPN clients may be different, it is necessary to determine which domain name service resources correspond to a VPN client in order to access the domain name service resources, for example, the domain name service resources corresponding to a current VPN client may be determined according to an access right of a user logging in the VPN client, and after determining a plurality of domain name service resources corresponding to the VPN client, domain names corresponding to the domain name service resources need to be determined, so as to determine an IP address corresponding to the domain name according to the domain name in the following.
For example, the plurality of domain name service resources corresponding to a certain VPN client may include: service resource B, service resource C, and service resource D.
And S120, acquiring the network protocol IP address corresponding to the domain name.
Because the domain name is only convenient for the reading and memory of the user, the VPN client cannot directly process the domain name, and therefore, the network protocol IP address corresponding to the domain name needs to be acquired, that is: the domain name is converted to a corresponding IP address. Specifically, the Domain Name can be converted into a corresponding IP address by a Domain Name System (DNS). Among other things, DNS can be understood to be a distributed database in nature that provides services for converting domain names into IP addresses.
In this embodiment, the domain name may be resolved by a preconfigured domain name centralized resolution device, so as to obtain an IP address corresponding to the domain name.
S130, storing the corresponding relation between the domain name and the IP address to a local cache.
After the IP address corresponding to the domain name is obtained, in order to facilitate subsequent domain name service resource access, the corresponding relationship between the domain name and the IP address needs to be stored in the local cache, so that the subsequent domain name service resource access request triggered by the user can be responded, and the IP address corresponding to the domain name service resource can be directly obtained from the local cache, thereby saving time and improving access speed.
And S140, responding to the domain name service resource access request triggered by the user, and acquiring the IP address corresponding to the domain name service resource from the local cache.
The domain name service resource in the domain name service resource access request may be at least one of a plurality of domain name service resources corresponding to the VPN client.
After the user sends the domain name service resource access request to the VPN client, the VPN client can respond to the domain name service resource access request triggered by the user and acquire an IP address corresponding to the domain name service resource from a local cache so as to access the domain name service resource through the IP address in the following process.
And S150, accessing the domain name service resource through the IP address.
After the IP address corresponding to the domain name service resource is acquired from the local cache, the domain name service resource can be directly accessed through the IP address.
In this embodiment, different from the prior art, by obtaining domain names corresponding to a plurality of domain name service resources corresponding to a virtual private network VPN client, and obtaining IP addresses corresponding to the domain names, and then storing a correspondence between the domain names and the IP addresses in a local cache, after a user triggers a domain name service resource access request, the VPN client can directly respond to the domain name service resource access request, obtain the IP addresses corresponding to the domain name service resources from the local cache, and access the domain name service resources through the IP addresses, so that a step of domain name resolution is not required each time a service resource corresponding to a domain name is accessed, waste of bandwidth resources is avoided, and an existing way of accessing the service resources through the domain name is optimized.
In this embodiment, optionally, before the acquiring, in response to a domain name service resource access request triggered by a user, an IP address corresponding to the domain name service resource from the local cache, the method further includes:
and responding to the login of the user on the VPN client, and establishing a VPN communication tunnel.
Specifically, after receiving a login request of a user, the VPN client may initiate a communication tunnel establishment request to the VPN gateway, so as to ensure that the user can access the corresponding domain name service resource through the established communication tunnel.
According to the embodiment of the disclosure, through establishing the VPN communication tunnel, a guarantee is provided for a user to access domain name service resources.
Fig. 2 is a schematic flowchart of a domain name service resource access method provided by an embodiment of the present disclosure. The embodiment is optimized on the basis of the embodiment. Optionally, this embodiment explains in detail a process of obtaining domain names corresponding to a plurality of domain name service resources corresponding to the VPN client and obtaining IP addresses corresponding to the domain names.

And S220, acquiring domain names corresponding to the domain name service resources according to the configuration information.
After the configuration information corresponding to the VPN client is obtained, according to domain names corresponding to the domain name service resources included in the configuration information, domain names corresponding to the domain name service resources can be obtained, so that a domain name resolution request is subsequently sent to the DNS for each domain name, and a domain name resolution response returned by the DNS is obtained, that is: and IP addresses corresponding to the domain names.
S230, sending a domain name resolution request to a Domain Name System (DNS) aiming at each domain name; and receiving a domain name resolution response returned by the DNS, wherein the domain name resolution request comprises a domain name, and the domain name resolution response comprises an IP address corresponding to the domain name.
And sending a domain name resolution request to the DNS aiming at each domain name, wherein the domain name resolution request comprises the domain name, the DNS analyzes the current domain name after receiving the domain name resolution request so as to obtain an IP address corresponding to the current domain name, and then the DNS returns a domain name resolution response to the VPN client. And the VPN client receives a domain name resolution response returned by the DNS, wherein the domain name resolution response comprises an IP address corresponding to the domain name.
S240, storing the corresponding relation between the domain name and the IP address to a local cache.
And S250, responding to the domain name service resource access request triggered by the user, and acquiring the IP address corresponding to the domain name service resource from the local cache.
And S260, accessing the domain name service resource through the IP address.
In this embodiment, first, configuration information corresponding to a VPN client is obtained, where the configuration information includes: the method comprises the steps that domain names corresponding to a plurality of domain name service resources respectively are obtained according to configuration information, then, a domain name resolution request is sent to a Domain Name Server (DNS) according to each domain name, a domain name resolution response returned by the DNS is received, the domain name resolution request comprises the domain name, the domain name resolution response comprises an IP address corresponding to the domain name, therefore, the IP addresses corresponding to all the domain names respectively are obtained, then, the corresponding relation between the domain name and the IP address is stored in a local cache, the IP address corresponding to the domain name service resources is obtained from the local cache in response to a domain name service resource access request triggered by a user, and finally, the domain name service resources are accessed through the IP addresses. In the scheme, by acquiring domain names corresponding to a plurality of domain name service resources respectively, acquiring an IP address corresponding to each domain name through a DNS (domain name system) aiming at each domain name, then establishing a corresponding relation between the domain name and the IP address, and storing the corresponding relation in a local cache, so that a subsequent VPN client can directly respond to a domain name service resource access request, acquire the IP address corresponding to the domain name service resource from the local cache and access the domain name service resource through the IP address, thereby avoiding the step of domain name resolution when accessing the service resource corresponding to the domain name every time, avoiding the waste of bandwidth resources, optimizing the existing mode of accessing the service resource through the domain name, reducing the frequency of requesting the DNS server, and acquiring the IP address corresponding to the domain name service resource from the local cache when the network communication condition of the VPN client and the DNS server is poor, the problem that the access speed is slow and even the access is failed is avoided.
In this embodiment, optionally, the method of this embodiment further includes:
and under the condition of preset triggering, updating the corresponding relation between the domain name and the IP address stored in the local cache.
The preset trigger condition may be pre-designed, or may be determined according to a specific situation, and this is not specifically limited in the embodiments of the present disclosure.

and triggering and updating the corresponding relation between the domain name and the IP address stored in the local cache in response to the configuration information which is modified.
Specifically, an update period may be set by a timer, for example, the update is performed every 10 minutes, so that the correspondence between the domain name and the IP address stored in the local cache is periodically updated, that is: sending a domain name resolution request to the DNS every other period, receiving a new domain name resolution response returned by the DNS, and updating the corresponding relation between the domain name and the IP address stored in the local cache according to the IP address corresponding to the domain name contained in the domain name resolution response; or after receiving the configuration information which is sent by the user and is modified, the VPN client sends a new domain name resolution request to the DNS in response to the configuration information which is modified, because the domain names corresponding to the multiple domain name service resources in the configuration information may also be changed after the configuration information is modified, where the new domain name resolution request includes: and receiving a new domain name resolution response returned by the DNS according to all domain names included in the modified configuration information, and updating the corresponding relation between the domain name and the IP address stored in the local cache according to the IP address corresponding to all the domain names included in the new domain name resolution response. For example, if there is a new domain name in the modified configuration information, the final correspondence between the domain name and the IP address needs to include not only the original correspondence between the domain name and the IP address but also the new correspondence between the domain name and the IP address.
According to the embodiment of the disclosure, the corresponding relation between the domain name and the IP address stored in the local cache is periodically updated; or, in response to the configuration information after modification, triggering and updating the corresponding relationship between the domain name and the IP address stored in the local cache, so that the corresponding relationship between the domain name and the IP address stored in the local cache is more accurate, and better meets the requirement of practical application, thereby further improving the efficiency and accuracy of accessing domain name service resources through the IP address subsequently.
