Description

domain name resolution method, access method of application server and terminal thereof

Technical Field

The invention relates to the field of application programs, in particular to a domain name resolution method, an access method of an application server and a terminal thereof.

background

before the application client of the terminal is used online, a test is required to ensure that the application client of the terminal is operated safely and stably in the using process. From development to online, an application client of the terminal needs to go through different network environments for application client testing, for example, in a development stage, a development environment is needed for testing, in a testing stage, a network environment is needed for testing, and in an experience stage, an experience environment is needed for testing.

And the terminal is required to switch different network environments for testing at different stages of the application client. Currently, the switching of the network environment is mainly performed in the following two ways:

1) The IP address of an application server needing to be accessed is modified in an application client code of the terminal, a hard coding mode is adopted, or a hidden operation entrance mode is opened in the application client of the terminal, the testing domain name and the IP address are written into application clients of different versions, and the application client of the terminal can directly access the application server through the testing domain name and the IP address written into the application client. Because the application servers in different network environments have different IP addresses, the codes in the application client side need to be rewritten each time the test is performed, and the process of writing the codes is complex;

2) The method comprises the steps of configuring a database of the website domain name and the corresponding IP address on the terminal, and supporting the terminal to access different network environments by continuously modifying the content in the database. However, the configuration of the database on the terminal can be completed only by complex operations, testing and experiencing personnel often do not have the skills or tools, and professional personnel are required to perform complex database construction on each terminal, so that not only is the labor cost increased, but also the testing efficiency is reduced, and the whole testing process is complex.

The method has the main problems that the application clients with different versions are required to be packaged in different network environments, the application clients with network environment information are very easy to release, and the application clients cannot be normally used. In addition, the process of configuring data on a terminal is complicated, and since the configured data is distributed over a plurality of terminals, it is very difficult to maintain.

It can be seen that, in the current scheme, corresponding network environment information is configured on the terminal for different network environments, and the process of configuring the network environment information is relatively complex, which may cause a problem that the terminal is relatively complex and relatively high when testing. However, no effective solution has been proposed to the above technical problems.

Example 1

In accordance with an embodiment of the present invention, there is provided an embodiment of a method that may be performed by an embodiment of the apparatus of the present application, it being noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here. According to an embodiment of the present invention, a domain name resolution method is provided.

Alternatively, in this embodiment, the domain name resolution method described above may be applied to a hardware environment formed by the terminal 101, the DNS server 102, and the application server 103 shown in fig. 1. As shown in fig. 1, a terminal 101 is connected to a DNS server 102 via a network, the DNS server 102 transmits a domain name resolution result to the terminal 101, and the terminal 101 accesses an application server 103 according to the resolved domain name provided by the DNS server 102. Such networks include, but are not limited to: one or more local area networks, the terminal 101 including but not limited to a cell phone, a PC, a notebook, or a tablet.

The domain name resolution method provided by the embodiment of the invention is shown in fig. 2. The domain name resolution method shown in fig. 2 includes the following steps S202 to S206.

step S202, the domain name system server 102 receives a request message sent by the terminal 101, wherein the request message carries an IP address of the terminal 101 in a connected network and a domain name of the application server 103 requested to be accessed by the terminal 101;

Step S204, the domain name system server 102 searches DNS mapping information under a preselected network environment corresponding to the IP address to obtain the IP address of the application server 103 under the network environment, wherein the DNS mapping information records a first mapping relation between the domain name of the application server 103 under the network environment and the IP address of the application server 103;

In step S206, the domain name system server 102 transmits the IP address of the application server 103 in the network environment to the terminal 101.

The terminal 101 is connected to different networks and has different IP addresses, and in order to enable the domain name system server 102 to determine an object for receiving information, the request information of the terminal 101 carries the IP address of the terminal in the connected network; the request information further includes the domain name of the application server that the terminal 101 requests to access, so that the domain name system server 102 can perform domain name resolution. The domain name of the application server carried in the request information of the terminal 101 is the domain name in the column of the domain name of the application server in table 1.

Table 1 structure diagram of configuration information of network environment

and the preselected network environment is reported to the domain name system server by the terminal. The preselected network environments are the test environment and the development environment in table 1, and the running environment of the application client on the terminal is simulated in different network environments to test the corresponding functions. Table 1 shows DNS mapping information in a preselected network environment.

The DNS mapping information is a mapping relationship between a domain name of the application server and an IP address of the application server in a predetermined network environment, and as shown in table 1, when the environment name is a test environment, the domain name imgcache.qq.com of the application server and the IP address 10.130.24.31 of the application server have a mapping relationship, that is, a first mapping relationship. When the environment name is the development environment, the mapping relationship between the domain name i.gtimg.cn of the application server and the IP address 10.185.20.211 of the application server is the first mapping relationship. Of course, the mapping relationship between the domain names of the other application servers and the IP addresses of the application servers shown in table 1 is also included in the first mapping relationship, and it should be understood that the first mapping relationship includes not only the mapping relationship between the domain names of the application servers shown in table 1, but also the mapping relationship between the domain names of the other application servers not shown in table 1.

the domain name system server 102 resolves the domain name of the application server carried in the request information of the terminal 101 into the IP address of the application server according to the first mapping relation in table 1, and sends the resolved IP address back to the terminal. For example, if the domain name of the application server to which the terminal 101 requests access is p.qq.com and the network environment to which access is requested is a development environment, the domain name system server 102 resolves that IP address of the application server is 10.130.25.95 and sends back the IP address 10.130.25.95 to the terminal 101.

as shown in fig. 3, the terminal 101 sends the domain name of the application server requesting access to the domain name system server 102, the domain name system server 102 searches for the first mapping relationship, and maps the domain name of the application server to the IP address of the application server according to the first mapping relationship, and the domain name system server sends the IP address obtained by mapping.

Through the embodiment, the domain name system server receives the IP address of the terminal and the domain name of the application server requesting access sent by the terminal, searches the DNS mapping information in the preselected network environment according to the preselected network environment of the terminal, maps the domain name of the application server requested by the terminal into the IP address of the application server in the network environment, and sends the IP address of the application server obtained through mapping back to the terminal. The terminal selects the network environment and informs the network environment selected by the domain name system server and the domain name of the accessed application server, the domain name system server sends the IP address of the application server to the terminal, the IP address or the domain name of the application server does not need to be configured by a code on the terminal, the domain name of the application server is converted into the IP address through the DNS mapping information on the domain name system server, the terminal can access the application server according to the IP address sent by the domain name system server, namely, the DNS mapping information is configured on the domain name system server, no matter how many application servers the terminal needs to access, the IP address of the application server which requires to be accessed can be resolved by utilizing the configured DNS mapping information as long as the network environment is pre-selected, the IP address or the domain name of the application server which needs to be accessed does not need to be configured for each terminal, the problem of higher complexity caused by the fact that the application server address under the network environment is configured on each terminal in the prior art is solved, the effect of repeatedly using DNS mapping information configured once is achieved, and the complexity of configuring the address of the application server is reduced.

Optionally, before the domain name system server 102 receives the request message sent by the terminal 101, the domain name system server 102 receives an IP address of the terminal 101 in the connected network and an identifier of the network environment selected by the terminal; the domain name system server 102 configures DNS mapping information in the network environment for the network environment indicated by the identifier; the domain name system server 102 stores a second mapping relationship between the IP address of the terminal 101 in the connected network and the DNS mapping information under the configured network environment.

The domain name system server 102 configures DNS mapping information for the network environment indicated by the terminal 101, and the domain name system server 102 stores a second mapping relationship between the IP address of the terminal 101 and the DNS mapping information in the network environment as shown in table 2.

TABLE 2 mapping relationship of terminal IP address, network environment identifier and DNS mapping information

As shown in table 2, the IP address of the terminal 101 in the connected network is 172.25.32.202, and the value 123 or 456 is used as the network environment identifier, where 123 represents the network environment where the application server 103 is located as the test environment. 456 represents a development environment as a network environment in which the application server 103 is located. It should be noted that the numerical values 123 and 456 are only used as an illustration of the network environment identifier, and may also be a combination of words, letters, or symbols, and combinations thereof.

the present embodiment is described below with reference to table 2. In this embodiment, the domain name system server 102 receives that the IP address of the terminal 101 in the connected network is 172.25.32.202, the network environment selected in advance by the terminal 101 is the test environment, the network environment identifier corresponding to the test environment in the domain name system server 102 is 123, the domain name of the application server requested to be accessed by the terminal 101 is p.qq.com, the domain name system server 102 finds that the IP address corresponding to the domain name p.qq.com is 10.12.23.155 according to the network environment identifier, the domain name system server 102 sends the IP address 10.12.23.155 of the application server back to the terminal 101 according to the IP address of the terminal 101 in the connected network, and the terminal 101 can access the application server with the domain name p.qq.com according to the IP address 10.12.23.155. Through the embodiment, the domain name system server 102 can configure DNS mapping information in a network environment for the network environment indicated by the identifier of the network environment, and store the second mapping relationship between the IP address of the terminal 101 and the DNS mapping information in the network environment, and when the terminal 101 accesses different application servers in the same network environment, the IP address of the application server in the corresponding network environment can be found according to the IP address of the terminal 101, so that the efficiency of the domain name system server in mapping a domain name to an IP address is improved.

Further, before the domain name system server receives the request message sent by the terminal, and after the domain name system server stores the mapping relationship between the IP address of the terminal in the connected network and the DNS mapping information under the configured network environment, the method further includes: a domain name system server receives an updated IP address sent by a terminal; the domain name system server replaces the IP address corresponding to the DNS mapping information in the second mapping relation with the updated IP address; and the IP address carried in the request message is the updated IP address.

Before the domain name system server 102 receives the request message sent by the terminal 101, the terminal 101 sends the MAC address of the terminal 101 to the domain name system server 102 to indicate that the domain name system server 102 has the terminal 101 connected to it. Due to the global uniqueness of the MAC address, the domain name system server 102 is able to identify the unique terminal 101 from the MAC address.

The domain name server 102 also stores the mapping relationships as shown in table 3.

TABLE 3 mapping relationship between MAC address of terminal, IP address of terminal and DNS mapping information in network environment

as shown in table 3, the MAC address of the terminal is 00-23-5A-15-99-42, but the IP address of the terminal 101 is different due to the different networks to which the terminal 101 is connected, and in this embodiment, the IP addresses of the terminal 101 in the three networks are 172.25.32.202, 171.25.32.202, and 170.25.32.202, respectively.

since the IP address of the terminal 101 is caused by different networks connected to the terminal 101, and the terminal 101 itself does not change, the mapping relationship between the terminal 101 and the DNS mapping information in the network environment does not change due to the change of the network connected to the terminal 101. For example, in this embodiment, the terminal 101 may have different IP addresses in the connected networks, such as 172.25.32.202 or 171.25.32.202, and the item of the test and the network environment identifier that the same terminal 101 needs to perform do not change due to the change of the IP address of the terminal 101, so when the terminal 101 is connected to different networks to access the domain name system server 102, the IP address of the terminal 101 connected to different networks and the DNS mapping information under the network environment identifier may be used as the second mapping relationship according to the MAC address of the terminal 101.

through the embodiment, when the IP address of the terminal 101 changes due to a change in the network to which the terminal 101 is connected, the mapping relationship between the IP address of the terminal 101 and the DNS mapping information in the network is established, so that when the IP address of the terminal 101 changes, the second mapping relationship between the IP address of the terminal and the DNS mapping information in the network environment does not need to be established again, and only the updated IP address of the terminal 101 needs to be replaced by the updated IP address, thereby saving resources of the domain name system server. Of course, an updated IP address may also be added, as shown in table 3. After updating the IP address of the terminal 101, the updated IP address is sent to the domain name system server, so that the domain name system server 102 accurately sends the IP address of the application server to the terminal 101 according to the updated IP address.

Example 2

There is also provided, in accordance with an embodiment of the present invention, an embodiment of a method that may be performed by an embodiment of the apparatus of the present application, it being noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here. According to an embodiment of the invention, an access method of an application server is provided.

Alternatively, in this embodiment, the access method of the application server may be applied to a hardware environment formed by the terminal 101, the DNS server 102, and the application server 103 shown in fig. 1.

fig. 4 is a flowchart of an access method of an application server according to an embodiment of the present invention. As shown in the figure, the access method of the application server includes the following steps S402 to S408.

Step S402, the terminal 101 sends the IP address of the terminal in the connected network and the identifier of the network environment selected by the terminal to the domain name system server 102;

Step S404, the terminal 101 sends a request message to the domain name system server 102, wherein the request message carries an IP address and a domain name of the application server 103 which the terminal requests to access;

Step S406, the terminal 101 receives the IP address of the application server 103 in the network environment sent by the domain name system server 102 in response to the request message;

In step S408, the terminal 101 accesses the application server through the IP address of the application server 103.

As shown in fig. 5, the terminal 101 transmits the IP address of the terminal and the identification of the network environment selected by the terminal to the domain name system server 102 to inform the domain name system server 102 that the terminal 101 has access. The terminal 101 sends the domain name of the application server 103 requesting access to the domain name system server 102. After the domain name system server 102 resolves the domain name into the IP address, the terminal 101 receives the IP address of the application server, and the terminal 101 accesses the application server 103 through the received IP address of the application server 103.

The network environment is identified in this embodiment as 172.25.32.202. The following describes the technical solution of the present example with reference to table 4.

Table 4 structure diagram of configuration information with identification of network environment

the identifier of the network environment selected by the terminal 101 may be T or K shown in table 4, and is used to indicate that the network environment in which the application server 103 is located is a test environment and a development environment, respectively. The domain name of the application server 103 carried in the request message sent by the terminal 101 may be imgcache.qq.com, i.gtimg.cn, and p.qq.com shown in table 4, or may be a domain name of another application server not shown in table 4. In the test environment, the IP address of the application server mapped by the domain name imgcache. qq. com of the application server is 10.130.24.31, and the mapping relationship between the domain name and the IP address in the network environment is shown in table 4, which is not described in detail herein. After the terminal 101 transmits the domain name requested for access, it receives the IP address of the application server from the domain name system server 102 in response to the request information, and accesses the application server according to the IP address.

through the above embodiment, the terminal 101 selects the network environment where the accessed application server is located, and sends the identifier of the selected network environment to the domain name system server 102, and the domain name system server 102 maps the domain name of the application server to the IP address of the application server according to the identifier of the network environment sent by the terminal 101, in this process, the domain name system server does not need to encode the terminal and the application client to be tested on the terminal, and the domain name system server can convert the domain name to the IP address, the terminal only needs to send the identifier of the network environment where the application server is located to the domain name system server, and does not need to configure the IP address or the domain name of the application server to be accessed for each terminal, thereby solving the problem of high complexity caused by configuring the address of the application server in the network environment on each terminal in the prior art, the effect of configuring DNS mapping information for multiple times is achieved, and therefore the complexity of configuring the address of the application server is reduced.

Optionally, the terminal sends the IP address of the terminal in the connected network and the identifier of the network environment selected by the terminal to the domain name system server: the terminal receives the identification of the network environment currently existing; the terminal displays the identification of the network environment currently existing, and selects the identification of one network environment from the identification of the network environment currently existing according to the received operation instruction; and the terminal sends the identification of the selected one network environment and the IP address of the terminal in the connected network to the domain name system server.

the identification of the network environment currently existing for the terminal 101 may be a test environment or a T-experience environment in the interface diagram shown in fig. 6. Displaying the identifiers of the currently existing network environments on the terminal 101, and selecting an identifier of one network environment from the identifiers of the network environments displayed in the terminal 101 according to the received operation instruction, for example, the identifier of the selected network environment in fig. 6 is a T experience environment. The terminal 101 sends the identifier of the network environment selected by the operation instruction to the domain name system server 102, so that the domain name system server 102 maps the domain name of the application server to the IP address of the application server according to the network environment selected by the terminal 101.

The terminal sends the selected network environment identifier and receives the IP address of the application server obtained by analyzing the domain name of the application server by the domain name system server so as to access the application server, the application client capable of accessing different application servers does not need to be packaged in the process, the application server does not need to be accessed by encoding the application client to be tested, and the mapping process from the domain name to the IP address is completed by the domain name system server, so that the problem of higher complexity caused by the fact that the application server address under the network environment is configured on each terminal in the prior art is solved, the test under different network environments can be carried out by carrying out simple network environment selection work on the terminal, and the test efficiency of the application client on the terminal is improved.

Optionally, after the terminal sends the IP address of the terminal in the connected network and the identifier of the network environment selected by the terminal to the domain name system server, the method further includes: the domain name system server configures DNS mapping information under a network environment for the network environment indicated by the identifier, wherein the DNS mapping information records a first mapping relation between a domain name of an application server under the network environment and an IP address of the application server; the domain name system server stores a second mapping relation between the IP address of the terminal in the connected network and the identifier of the network environment selected by the terminal;

After the terminal sends the request message to the domain name system server, the method further comprises: and the domain name system server acquires the identifier of the network environment selected by the terminal corresponding to the IP address of the terminal in the network connected with the terminal according to the second mapping relation, acquires the IP address of the application server in the network environment corresponding to the domain name of the application server according to the first mapping relation recorded in the DNS mapping information in the network environment indicated by the identifier, and sends the IP address of the application server in the network environment to the terminal.

The content recorded in the DNS mapping information may be as shown in tables 1 to 3, where a first mapping relationship between a domain name of an application server in a network environment and an IP address of the application server is recorded in tables 1 to 3, and a second mapping relationship between an IP address of the terminal 101 in a connected network and an identifier of a selected network environment is also recorded in tables 2 and 3, for example, the mapping relationship between the IP address 172.25.32.202 of the terminal and a test environment is the second mapping relationship in table 2.

Based on the IP address 172.25.32.202 of the terminal 101, the domain name system server 102 determines that the network environment selected by the terminal 101 is a test environment. In this embodiment, the domain name of the application server requested to be accessed by the terminal 101 is imgcache. qq.com, and the IP address of the application server corresponding to the domain name is found from the first mapping relationship and is 10.130.24.31.

When the terminal 101 receives that the IP address of the application server sent by the domain name system server 102 is 10.130.24.31, the terminal 101 accesses the application server according to the IP address to perform a test.

Further, after the domain name system server 102 stores the second mapping relationship between the IP address of the terminal 101 in the connected network and the identification of the network environment selected by the terminal 101, the method further includes: the domain name system server 102 receives the updated IP address sent by the terminal 101; the domain name system server 102 determines that the updated IP address is sent by the terminal 101 according to the MAC address of the terminal 101 received in advance, and replaces the IP address corresponding to the DNS mapping information in the second mapping relationship with the updated IP address.

TABLE 5 mapping relationship between MAC address of terminal, IP address of terminal, and DNS mapping information in network environment

table 5 shows a mapping relationship between the MAC address of the terminal, the IP address of the terminal, and DNS mapping information in the network environment. Before the terminal 101 sends request information to the domain name system server 102, the terminal 101 sends the MAC address of the terminal to the domain name system server 102 for registration, and the domain name system server 102 knows which terminal is connected to the domain name system server according to the MAC address of the terminal 101.

When the IP address of the terminal 101 changes, because the first mapping relationship does not change with the IP address of the terminal 101, after the terminal 101 reports its IP address, the dns server 102 determines that the new IP address belongs to the same MAC address, and the MAC address has global uniqueness, finds the original IP address corresponding to the MAC address and updates the original IP address, and the updated IP address has the second mapping relationship with the network environment identifier, and can also perform domain name to IP address conversion by using the original mapping relationship.

for example, if the new IP address of the terminal 101 is 170.25.32.202, the IP address 172.25.32.202 of the terminal in table 5 is updated to 170.25.32.202, and the domain name system server 102 receives the network environment identifier sent by the terminal with IP address 170.25.32.202, and searches for the IP address of the application server corresponding to the domain name i.gtimg.cn of the application server requesting access to be 10.130.24.31 under the network environment identifier.

and updating the IP address of the terminal in the mapping relation configured in the domain name server according to the MAC of the terminal, and corresponding the updated IP address with the network environment identifier under the condition of not changing the first mapping relation, thereby avoiding reconfiguring the first mapping relation and the second mapping relation in the domain name server and facilitating the maintenance of the mapping relation in the domain name server.

Optionally, the accessing, by the terminal 101, the application server 103 through the IP address of the application server 103 includes: the terminal 101 interacts with the application server 103 through the IP address of the application server 103 for data used for testing an application client installed on the terminal 101.

After the terminal 101 receives the IP address of the application server 103 sent by the domain name system server 102, the terminal 101 accesses the application server according to the IP address of the application server 103, and since the application server is in a preselected network environment, the application client installed on the terminal interacts with the application server 103 in test data, so as to achieve the purpose of testing in the predetermined network environment.
