In the device embodiment shown in FIG. 1, the memory 11 as a computer storage medium may include an operating system and a domain name resolution program; the network interface 13 is mainly used to connect to an application server, and perform data communication with the server, for example, a terminal. The network request is sent to the server based on the network interface 13; when the processor 12 executes the domain name resolution program stored in the memory 11, the following steps are implemented:

When the network request sent by the application is detected, the network request is parsed to obtain a target domain name corresponding to the network request.

Searching for a target IP address corresponding to the target domain name from a domain name and IP address mapping relationship table that matches the application.

The above application is installed and runs in the device in this embodiment. Each application has a pre-configured domain name and IP address mapping relationship table. When the developer develops the application, the application server sets the domain name that the application can access and each The IP address corresponding to a domain name. A mapping between a domain name and an IP address can be established. The domain name and the corresponding IP address can be stored in the form of a list, and a mapping table between the domain name and the IP address is established and sent to the client.

For the terminal, there are many ways to obtain the mapping between the domain name and the IP address mapping table. Two of them are described below.

In the first method, when the application is started, the device obtains an acquisition request for obtaining a mapping between a domain name and an IP address according to the preset interface, and receives a mapping table between the domain name and the IP address sent by the application server according to the obtaining request, and caches To local.

At each startup, the application requests the latest domain name and IP address mapping relationship table from the application server to update and store the locally stored mapping table for use when the application makes a network request. In other embodiments, in order to ensure the security of the information, when the application is detected to be closed, the locally stored mapping table may be deleted, and each time the application is started, the latest mapping between the domain name and the IP address may be requested from the application server.

In a second manner, the processor 12 is further configured to execute a domain name resolution program stored in the memory 11 to search for a target IP address corresponding to the target domain name in a domain name and IP address mapping relationship table matched with the application. After the steps, the following steps are also implemented:

If the method is adopted, the terminal does not need to request the domain name and IP address mapping relationship table from the application server every time the application starts. When the network request is made in the application, the mapping between the domain name and the IP address of the local storage is preferentially used. When the domain name and the IP address mapping table stored locally are not found, the target IP address corresponding to the target domain name in the network request cannot be queried. Sending an update request to the application server to obtain the latest domain name and IP address mapping relationship table, and re-inquiring the target IP address, and when finding the corresponding target IP address, initiating a network request to the server corresponding to the target IP address. . Further, the latest mapping relationship table update can also be stored locally for subsequent use.

The following describes a specific application scenario as an example. Taking a mobile phone with an android system as an example, an APP on the mobile phone communicates with the server of the APP based on the HTTP protocol (Hyper Text Transfer Protocol), the APP initiates a network request, and the processor 12 acquires the network request. URL (Uniform Resource Locator) object, the URL includes protocol information, a network address, and a resource path, where the network address is generally a domain name, and the resource path is generally used to indicate which one to obtain from the application server. Item resources. The processor 12 calls the domain name resolution program to parse the network request to obtain the target domain name, and then calls the domain name and IP address mapping relationship table stored in the memory 11 to search for an IP address, a general domain name and an IP address that have a mapping relationship with the target domain name. There is a one-to-one or many-to-one relationship. Therefore, a target domain name generally has only one corresponding target IP address. After finding the corresponding IP address, a network request is initiated to the server corresponding to the target IP address, specifically The processor 12 organizes a requested data packet according to the requirements of the HTTP protocol. The data packet includes specific request information, including the requested resource path, the identity information of the terminal, and the like, so that the server searches for the corresponding resource data and returns. The mapping relationship table stored on the memory 11 may be when the APP is started, and the processor 11 requests the server to acquire and store.

Preferably, as another embodiment, the processor 12 is further configured to execute a domain name resolution program stored in the memory 11 to search for the target in a domain name and IP address mapping relationship table matched with the application. After the step of the destination IP address corresponding to the domain name, the following steps are also implemented:

In this embodiment, when the terminal does not find the target IP address matching the target domain name locally, the remote DNS server resolves the domain name as an auxiliary means. For the remote DNS server directly inquired by the terminal, when there is no IP address corresponding to the target domain name, it will ask its superior server, and the upper-level server may also have no, and then look up one layer at a time, up to the maximum Root node, found or not found.

For example, in the development and maintenance of the application, a new domain name may appear in the new version of the application, but the developer may update the domain name and IP address mapping table in the future, so that the target domain name cannot be found. When the destination IP address is used, the terminal directly sends the network request to the remote DNS server, and the DNS server performs domain name resolution. In addition, the network request includes the IP address of the terminal, and after the DNS server resolves the target IP address, the target IP address is sent to the terminal according to the IP address of the terminal.

Further, in other embodiments, the processor is further configured to execute the domain name resolution program to implement the following steps:

After receiving the target IP address obtained by the DNS server, the terminal may use the destination IP address to send a network request to the application server, or associate the IP address with the corresponding target domain name and report it to the application server for maintenance by the server. The domain name and IP address mapping relationship table is updated.

The domain name resolution device of the present embodiment, when detecting the network request sent by the application, directly parses the network request locally, obtains the target domain name requested by the network, and queries from the locally stored domain name and IP address mapping relationship table. Go to the target IP address corresponding to the target domain name, and directly initiate a network request to the server corresponding to the target IP address based on the found target IP address, and no longer rely on the remote DNS server for domain name resolution, even if the DNS server fails. Affects the normal access network. In addition, local domain name resolution improves the acquisition speed of the target IP address and speeds up the network response.

Optionally, in other embodiments, the domain name resolution program may also be divided into one or more modules, and one or more modules are stored in the memory 11 and are composed of one or more processors (this embodiment is The processor 12) is executed to complete the present invention. The term "module" as used in the present invention refers to a series of computer program instruction segments capable of performing a specific function, and is more suitable than the program to describe the execution process of the message pushing device in the domain name resolution device.

For example, in an embodiment, the domain name resolution program can be divided into a parsing module and a lookup module. And a sending module, wherein:

The parsing module is configured to parse the network request to obtain a target domain name corresponding to the network request when detecting a network request sent by the application;

The searching module is configured to search for a target IP address corresponding to the target domain name from a domain name and IP address mapping relationship table that matches the application;

The sending module is configured to initiate a network request to the corresponding server based on the found target IP address.

In addition, the present invention also provides a domain name resolution method. Referring to FIG. 2, it is a flowchart of a preferred embodiment of the domain name resolution method of the present invention. The method can be performed by a device that can be implemented by software and/or hardware.

In this embodiment, the domain name resolution method includes:

Step S10: When detecting a network request sent by the application, parsing the network request to obtain a target domain name corresponding to the network request.

Step S20: Search for a target IP address corresponding to the target domain name from a domain name and IP address mapping relationship table matched with the application.

Step S30, initiating a network request to the corresponding server based on the found target IP address.

In the first manner, before the step S10, the method further includes the following steps:

When detecting that the application is started, the method for obtaining a domain name and IP address mapping relationship table is sent to the server according to the preset interface; and the domain name and IP address mapping relationship table sent by the application server based on the obtaining request is received and cached locally.

Manner 2, after step S20, the method of this embodiment further includes the following steps:

When the corresponding target IP address is found, step S30 is performed.

The following describes a specific application scenario as an example. Taking a mobile phone with an android system as an example, an APP on the mobile phone communicates with the server of the APP based on the HTTP protocol (Hyper Text Transfer Protocol), and the APP initiates a network request to obtain the URL of the network request. (Uniform Resource Locator) object, the URL includes protocol information, a network address, and a resource path, where the network address is generally a domain name, and the resource path is generally used to indicate which resource is obtained from the application server. . Calling the domain name resolution program to resolve the network request, obtaining the target domain name, and then searching for the IP address that has a mapping relationship with the target domain name from the domain name and IP address mapping relationship table. The one-to-one or multiple pairs between the general domain name and the IP address are used. A relationship, therefore, a target domain name generally has only one corresponding target IP address. After finding the corresponding IP address, a network request is initiated to the server corresponding to the target IP address, specifically, a request is organized according to the HTTP protocol requirement. The data packet contains specific request information, including the requested resource path and the identity information of the terminal, for the server to find the corresponding resource data and return. The mapping relationship table may be when the APP starts, and the terminal requests the server to acquire and store.

For example, in the development and maintenance of an application, a new domain may appear in a new version of the application. Name, but the developer can update the domain name and IP address mapping table in the future. Therefore, when the target IP address matching the target domain name is not found, the terminal directly sends the network request to the remote DNS server, and the DNS server Perform domain name resolution. In addition, the network request includes the IP address of the terminal, and after the DNS server resolves the target IP address, the target IP address is sent to the terminal according to the IP address of the terminal.

Further, in other embodiments, the method further includes the steps of: sending the received target IP address and the target domain name to the application server when receiving the target IP address obtained by the DNS server to parse the network request And the application server updates the domain name and IP address mapping relationship table based on the received target IP address and the target domain name.
