Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description.
The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as exemplary only and not as limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
In the related art, if a failure occurs in a main domain name currently in use and normal access to a service is not possible, normal access to the service is restored by restoring the main domain name in use. This approach requires a large amount of communication with the parties, submission of audit materials, even mailing of paper materials, etc., which can take a large amount of time and seriously affect the user experience.
In order to solve the above problem, the present application provides a domain name switching method and apparatus, and a computer-readable storage medium, which can quickly switch to an accessible standby domain name to provide a service for a user.
Fig. 1 illustrates a flow diagram of a domain name switching method according to some embodiments of the present disclosure.
As shown in fig. 1, the domain name switching method includes steps S1 to S4. In some embodiments, the domain name switching method is performed by the terminal.
In step S1 it is detected whether the current domain name can be used to access the target service.
For example, after an application program of the terminal is started, the main domain name currently in use is detected by accessing health check (service health check interface). If the interface returns: { code:0, message.
In step S2, in case the current domain name cannot be used to access the target service, a domain name switching policy is acquired from the public cloud.
For example, if it is detected that the primary domain name currently in use has no access to the target service, the application obtains the domain name switching policy from the third party's public cloud. The public cloud is a cloud service provided by a third-party service provider for a user, and is not a target service corresponding to a domain name. The domain name switching strategy is stored in the public cloud, and even under the condition that the target service cannot be accessed, the public cloud of a third party can be accessed, so that the application program can normally acquire the domain name switching strategy.
The handover policy includes behavior, pro-vince and city fields. Wherein, behavior represents the domain name switching mode, the province and the city respectively represent the province and the city of the domain name switching strategy. The public cloud provides an interface for acquiring a domain name switching strategy, and the name of the interface isstragy。
In addition to storing the domain name switching policy in the public cloud, a plurality of standby domain names are also stored in the public cloud. For example, a domain name list would include 10-20 alternate domain names: com, zhost.com, \ 8230; \8230; zhost.com, stored on public clouds. And providing an interface for acquiring the standby domain name by the public cloud, wherein the interface name is domains.
In step S3, the target standby domain name is determined according to the domain name switching policy.
For example, an attempt is made to find an alternate domain name that can be used. The domain name switching policy can specify the standby domain name as the target standby domain name. The application program can also search for a plurality of standby domain names acquired from the public cloud according to the domain name switching strategy. In the case where an available standby domain name is found, it is taken as a target standby domain name.
Fig. 2 illustrates a flow diagram for determining a target alternate domain name according to some embodiments of the present disclosure.
As shown in fig. 2, determining the target standby domain name according to the domain name switching policy includes steps S301 to S303.
In step S301, a domain name switching mode is determined according to a domain name switching policy, where the domain name switching mode includes a first switching mode and a second switching mode. For example, the first switching mode is an auto (automatic) switching mode, and the second switching mode is a manual mode.
In step S302, if the domain name switching mode is the first switching mode, a plurality of standby domain names are acquired from the public cloud. For example, in auto-switching mode, the application obtains a list of a plurality of alternate domain names from the public cloud.
In step S303, a target alternate domain name that can be used to access the target service is determined from the plurality of alternate domain names. For example, among a plurality of standby domain names returned by the public cloud, a standby domain name that can be normally accessed is automatically searched for as a target standby domain name.
In some embodiments, a domain name switching policy is obtained from a public cloud through a policy interface; a plurality of standby domain names are obtained from a public cloud through a domain name interface. For example, the application program obtains the domain name switching policy from the public cloud through a string interface; and acquiring a plurality of standby domain names from the public cloud through the domains interface.
Although the application program is internally provided with a default standby domain name list when being issued, the updating timeliness of the terminal is poor, and if the domain name is changed for many times in a short period, the timeliness of the standby domain name locally stored by the application program is poor and can be changed and failed at any time. Therefore, the latest standby domain name list is obtained from the public cloud, and the timeliness of the standby domain names is guaranteed. Through a public cloud and local multiple backup mechanism, the standby domain name can be obtained under various conditions, and the robustness of the scheme can be improved.
In some embodiments, determining a target alternate domain name from the plurality of alternate domain names that can be used to access the target service comprises: detecting whether a plurality of standby domain names can be used for accessing the target service one by one until the standby domain name which can be used for accessing the target service is found. For example, the application looks up the domain names returned by the cloud service one by one, looking for available domain names.
In some embodiments, detecting, one by one, whether multiple alternate domain names can be used to access the target service includes: through the health check interface, it is detected one by one whether the standby domain name can be used to access the target service. For example, the method of detecting the alternate domain name is through a health check interface as is the method of detecting the current domain name.
Fig. 3 illustrates a schematic diagram of a first switching pattern according to some embodiments of the present disclosure.
As shown in fig. 3, after the application program is started, if the detection of the current default main domain name is not passed, which indicates that the main domain name cannot be accessed, a plurality of latest standby domain names are obtained from the public cloud, and the obtained standby domain names are stored locally. Starting from the first standby domain name array [ 1 ], detecting whether the ith standby domain name array [ i ] can be used for accessing the target service through accessing a service health check interface until a target standby domain name which can be used is found. In addition, if i is greater than the total number count of the standby domain names, that is, the last standby domain name is detected to be unable to access the target service, which indicates that there is no available standby domain name, the meaning of switching the standby domain name is not large at this time, and the main domain name is used.
In some embodiments, in the case that the domain name switching policy cannot be acquired from the public cloud, the domain name switching mode in the domain name switching policy is determined to be the automatic switching mode. For example, if the application does not make a request to the string interface, or the string interface does not return a result, the domain name switching policy defaults to the auto-switching mode.
Fig. 4 illustrates a flow diagram for determining a target alternate domain name according to further embodiments of the present disclosure.
As shown in fig. 4, determining the target standby domain name according to the domain name switching policy includes steps S311-S314.
In step S311, a domain name switching mode is determined according to the domain name switching policy, where the domain name switching mode includes a first switching mode and a second switching mode.
In step S312, in the case that the domain name switching mode is the second switching mode, the standby domain name specified by the domain name switching policy is acquired. For example, in the case that the domain name switching mode is the second switching mode (manual switching), the standby domain name specified by the policy is already included in the domain name switching policy returned by the runtime interface provided by the public cloud. The specified backup domain name is, for example, a domain name configured for the area (province) where the terminal is located.
The difference between the domain interface and the string interface for returning the domain names is that the domain interface returns a complete domain name list, while in the manual switching mode, the string interface returns standby domain names specified by the policy.
In step S313, it is detected whether the specified standby domain name can be used to access the target service.
In step S314, in the case where the designated standby domain name can be used to access the target service, the designated standby domain name is determined as the target standby domain name. For example, the application detects whether the alternate domain name specified by the domain name switching policy can be used to access the target service, and if the alternate domain name specified by the domain name switching policy can be used to access the target service, then the specified alternate domain name is used as the target alternate domain name.
The manual switching mode refers to that in the background, a developer designates a specific domain name as a main working domain name, and the manual switching mode can be used for dealing with the special condition that all standby domain names are unavailable. In the manual switching mode, the designated standby domain name is determined based on dial testing monitoring alarms and manual confirmation. Under the condition that the default domains list cannot work normally, a specified standby domain name which is determined to be available can be used in a part of regions or all the regions, the control force is stronger, the phenomenon that all domain names lose the working capacity is avoided, and the normal access of the service is ensured.
Fig. 5 is a flowchart illustrating a process of determining a target standby domain name according to still other embodiments of the present disclosure, and as shown in fig. 5, in the process of determining a target standby domain name, after steps S311 to S314, steps S315 to S316 are further performed.
In step S315, in the event that the specified backup domain name cannot be used to access the target service, a plurality of backup domain names are obtained from the public cloud.
In step S316, a target alternate domain name that can be used to access the target service is determined from the plurality of alternate domain names.
For example, although the manual mode is mostly started when the default standby domain name list is not available, if the standby domain name specified by the domain name switching policy also fails to be accessed in the manual mode, the domain name list returned by domains is reused to perform a downgrading attempt, and more possibilities are found. At the moment, according to the same mode as the automatic switching mode, a plurality of standby domain names are obtained from the domains interface of the public cloud, and the standby domain names which can be normally accessed are searched from the standby domain names returned by the public cloud and serve as target standby domain names, so that the probability of finding the target standby domain names is improved, and the normal access of the service is ensured.
The method for searching the target standby domain name from the standby domain names returned from the domains interface is similar to the automatic switching method, and whether the standby domain names can be used for accessing the target service or not is detected one by one until the standby domain name which can be used for accessing the target service is found.
According to some embodiments of the present disclosure, the domain name switching policy specifies different switching modes, and under different conditions, different manners of determining the standby domain name are preferentially adopted, for example, when the standby domain name list may be valid, the first switching mode is adopted, the standby domain name list provided by the public cloud is preferentially traversed, and when the standby domain name list is likely to be invalid due to reasons such as untimely update, the second switching mode is adopted, and the standby domain name specified by the domain name switching policy is preferentially used. The method for determining the standby domain name according to the domain name switching strategy can adapt to different conditions, avoid waste of time caused by useless attempts and improve the flexibility and efficiency of domain name switching.
In some embodiments, obtaining a domain name switching policy from a public cloud comprises: and acquiring a domain name switching strategy corresponding to the position information of the terminal from the public cloud.
For example, the domain name switching policy is determined according to the location information of the terminal, and the domain name switching policies corresponding to different provinces and cities may be different. After the application program is started, the province and city area where the terminal is located are determined firstly. If the application program of the user terminal has the GPS authority or the GPS information is stored before, the province (district) where the current user is located is determined through the GPS information. And if no GPS related information exists, acquiring the IP address of the terminal by calling the three-party service, and determining the province and city area where the terminal is located according to the IP address. And then, acquiring a corresponding domain name switching strategy configured on the public cloud according to the province (district) where the user terminal is located.
By adopting different domain name switching strategies according to the regional characteristics of different provinces and cities, the flexibility and the efficiency of domain name switching can be improved.
In some embodiments, the standby domain name specified by the domain name switching policy is determined according to location information of the terminal. For example, in the domain name switching policy corresponding to different provinces and cities, the specified standby domain name may be different. Generally, there will not be many simultaneous domain name failures at the same time, but failures occur in a certain province, city. And aiming at the fault occurrence place, testing a domain name which can be normally accessed by using a dial testing mode, and taking the domain name as a standby domain name specified by a domain name switching strategy after the dial testing is normal.
In some embodiments, the target service is accessed via the IP address corresponding to the target service in the event that no alternate domain name is available to access the target service. For example, if no standby domain name can be used for normally providing the service, the real IP corresponding to the current domain name is acquired as a standby bottom-of-pocket scheme, and is forced to point to the server corresponding to the target service, so that the user can use the target service without abnormal perception.
In some embodiments, the IP address corresponding to the target service is obtained using a hypertext transfer protocol domain name system.
For example, if none of the standby Domain names can be used, the Domain Name System HyperText Transfer Protocol (http dns) is used to perform Domain Name resolution to obtain the real IP address. At an android terminal, configuring a local host file; and at the iOS end, accessing the service by using an agent mode through the real IP address, thereby really ensuring that the service can be normally accessed.
For the H5 page, the IP mode or the HTTPDNSd mode cannot be used, and the temporary domain name is used for solving the access problem.
Fig. 6 is a diagram illustrating a domain name switching method according to further embodiments of the present disclosure.
As shown in fig. 6, a domain name switch is first attempted to find a backup domain name that can be used for normal access by traversing the backup domain name list returned by the public cloud. If no available standby domain name is found after traversing the standby domain name list, an HTTPDNS method is used, an SDK (Software Development Kit) is used for resolving the domain name to obtain a real IP address, and the returned IP address is used for accessing the target service.
In addition, when the domain name is not available, other interactive pages are prompted to "service is temporarily unavailable and comes back later".
In some embodiments, at least one of the address of the policy interface and the address of the alternate domain name interface is updated at a first specified time.
For example, domains and runtime interface addresses provided by a public cloud are built in the application program. If the original public cloud suddenly fails to normally serve, the cloud provider is down for a long time or replaced, and the addresses of domains and the targets can be invalid. In order to solve the problem, the service provides an additional interface for updating the addresses of domains and struts provided by the public cloud, ensures that the application program can always obtain the latest standby domain name list and domain name switching strategy, and ensures an updating mechanism of the standby domain name list and the domain name switching strategy.
In some embodiments, the first specified time is when the application starts.
For example, when an application starts, the application accesses the service interface to obtain the latest public cloud domains and runtime interface addresses. And if the service interface can be accessed, updating the public cloud domains and the string interface address. And if the service interface cannot be accessed, acquiring a standby domain name list and a domain name switching strategy by using the default public cloud domains and the default strand interface addresses in the application program.
In some embodiments, at least one of the plurality of standby domain names and domain name switching policies stored by the public cloud is periodically updated to ensure timeliness of the standby domain names and domain name switching policies.
In step S4, the target service is switched from being accessed using the current domain name to being accessed using the target domain name. For example, the target standby domain name found to be able to normally access the target service is set as the default primary domain name through which the target service is accessed.
According to the domain name switching method of some embodiments of the present disclosure, when the current domain name cannot be used for normally accessing the target service, the domain name switching policy is acquired from the public cloud, and it is ensured that the latest domain name switching policy can be acquired also when the target service is inaccessible. According to the domain name switching strategy, the target standby domain name is determined, the standby domain name which can be used can be quickly found without waiting for the recovery of the current domain name, the application program is ensured to continuously provide services, the condition that the domain name is unavailable is avoided, and the user experience is improved.
