All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.

2. Host console (hereinafter simply console): and the business layer synchronizes the resources (states) of the platform and performs business operations such as binding of multiple resources, notification of resource orders and the like.
According to one aspect of the embodiments of the present application, a resource state synchronization method is provided. Alternatively, in the present embodiment, the above-described resource status synchronization method may be applied to a hardware environment constituted by the terminal 1402 and the server 1404 as shown in fig. 1. As shown in fig. 1, the server 1404 is connected to the terminal 1402 via a network, and may be used to provide services (such as game services, application services, etc.) to the terminal or clients installed on the terminal, and a database may be provided on the server or independent of the server, for providing data storage services to the server 1404.

The wired network may include, but is not limited to, at least one of: a wide area network, a metropolitan area network, a local area network, and the wireless network may include, but is not limited to, at least one of: WIFI (Wireless Fidelity ), bluetooth. The terminal may not be limited to a PC, a mobile phone, a tablet computer, or the like.
The resource state synchronization method in the embodiment of the application may be executed by a server, may be executed by a terminal, or may be executed by both the server and the terminal. The method for synchronizing the resource states by the terminal according to the embodiment of the present application may be performed by a client installed thereon.
Taking the method of resource status synchronization in this embodiment performed by a server as an example, fig. 2 is a flowchart of a method of resource status synchronization provided in this embodiment, applied to a console, and includes the following steps:
step S101, establishing a long connection with the platform.
The resource status synchronization method in this embodiment may be applied to a scenario of information synchronization at the time of asynchronous call, for example: the virtual machine is requested to be created at the front end, and the platform feeds back the virtual machine creation progress (i.e. the resource state in the scene is the virtual machine creation progress, which may be, for example, during creation, completion of creation, etc.) scene, etc. to the front end through the console, or may be other scenes for performing resource state synchronization. In the embodiment of the application, the above-mentioned resource state synchronization method is illustrated by taking the platform feeding back the creation progress of the virtual machine to the front end through the console, and the above-mentioned resource state synchronization method is also applicable to other types of resource states under the condition of no contradiction.
Specifically, the console may actively initiate a long connection establishment request to the platform, and after the platform responds to the console, the long connection between the console and the platform may be established.
Step S102, under the condition that the platform determines that the target resource has a change event and generates the current resource state information of the target resource, the current resource state information of the target resource is obtained through long connection, wherein the current resource state information is used for indicating the state of the target resource after the change event occurs.
Specifically, the platform may obtain the change of the underlying resource to determine whether a change event occurs in the target resource.
The target resource may be any resource, for example, any virtual machine that needs to be created, any hard disk that needs to be mounted, and so on.
Under the condition that the platform determines that the change event occurs to the target resource, the latest current resource state information of the target resource after the change event occurs can be generated.
Optionally, the platform may acquire the resource change of the bottom layer in real time, so as to determine whether the target resource has a change event.
After the platform generates the current resource state information of the target resource based on the change event, the current resource state information can be sent to the console through the pre-established long connection, so that the console can acquire the current resource state information.
Step S103, updating the local cache according to the current resource state information to complete synchronization of the current resource state information.
Specifically, after the console obtains the current resource status information, the console may update the local cache according to the current resource status information.
Optionally, updating the local cache may be: 1. replacing the local resource state information of the previous cache corresponding to the target resource with the current resource state information; 2. and adding the corresponding relation between the current resource state information and the target resource locally.
After the local cache is updated according to the current resource state information, synchronization of the current resource state information between the console and the platform is completed.
Further, after the synchronization of the current resource status information is completed, the console can directly use the current resource status information in the local cache in the subsequent process of real-time tracking and event notification to the front end.
According to the method, under the condition that a change event occurs to the target resource determined by the platform and current resource state information of the target resource is generated, the current resource state information of the target resource is obtained through long connection; therefore, the transmission of the resource state information between the platform and the console can be realized without adopting a message middleware; the control console can update the local cache according to the current resource state information to complete the synchronization of the current resource state information; therefore, when the operation of the later control console on the resource state information is convenient, the acquired resource state information can be more fully utilized, and the efficiency is effectively improved; furthermore, the method of the embodiment can effectively solve the technical problems that after the message middleware is introduced in the related technology, uncertainty is added to a call link between services and complexity is improved.
As shown in fig. 3, as an alternative embodiment, the method further includes, before the step S101 of establishing the long connection with the platform, the following steps:
step S201, obtaining initial resource state information of a target resource on a platform and an initial sequence identifier corresponding to the initial resource state information through a target interface on the platform, wherein the sequence identifier is used for indicating the time sequence of the resource state information corresponding to the sequence identifier in all the resource state information of the target resource.
Specifically, the console may obtain initial resource state information of all resources (including the target resource) in the aspects through using the RESTful API on the platform as the target interface. The RESTful API is an API interface that locates resources with URLs and describes operations with HTTP verbs (GET, POST, PUT, DELETE).
Meanwhile, the platform returns an initial sequence identifier which corresponds to each resource and is identified as sequence, and the sequence identifier corresponding to each resource monotonically increases in a global scope. For example, when the initial sequence identifier of the target resource is 1 and the sequence identifier is incremented in steps of 1, the sequence identifier becomes 2 after the change event occurs to the target resource.
For example, when the resource state is a virtual machine establishment state, the initial resource state may be a state for indicating that the virtual machine starts creation.
Step S202, the initial resource state information and the initial sequence identification are cached locally.
After the console obtains the initial resource status information and the initial sequence identifier, the console will cache the initial resource status information and the initial sequence identifier locally.
As an alternative embodiment, the method, for obtaining the current resource status information of the target resource through the long connection, includes the following steps:
step 3011, obtaining current resource state information of the target resource and a current sequence identifier corresponding to the current resource state information from the platform through long connection.
Specifically, after the long connection between the console and the platform is created, the console can track the change of the resource state of the target resource in real time, and the long connection is not disconnected, so that the platform can continuously notify the console of the event state.
Alternatively, the implementation of long connections may use Chunked Transfer Encoding of HTTP. This allows the platform to transmit event data to the console in real time by blocking when a new event occurs, without having to close the connection. The bound Encoding allows the data to be divided into a plurality of data blocks, each data block having its own unique corresponding length prefix, so that it can be transmitted block by block; and the control console can recover the current resource state information and the current sequence identifier based on the length prefix corresponding to each data block. This ensures real-time and uninterrupted communication of data transmissions.
By using the Chunked Transfer Encoding of HTTP, the platform can transmit corresponding events to the console in real time when the resource changes, and the console can continuously receive event notifications, so as to ensure timely update and synchronization of the resource state information.
Updating the local cache according to the current resource state information to complete the synchronization of the current resource state information, comprising:
step 3012, updating the local cache according to the corresponding current resource state information and the corresponding current sequence identifier, so as to complete synchronization of the current resource state information.
Specifically, after the console obtains the current resource status information and the current sequence identifier, the local cache of the console may be updated based on the current resource status information and the current sequence identifier, for example, the current resource status information and the current sequence identifier are added to the local cache, so as to complete synchronization of the current resource status information.
As an alternative embodiment, as in the foregoing method, before updating the local cache according to the current resource status information and the current sequence identifier corresponding to each other, the method further includes the following steps:
Step 401, determining a historical sequence identifier of the target resource that is cached locally last time.
Specifically, the local of the console at least caches the last received resource state information and the sequence identifier corresponding to each other, so that before the current resource state information is cached, the historical sequence identifier corresponding to the target resource and cached in the local last time can be determined.
Step 402, determining whether the difference between the current sequence identifier and the historical sequence identifier is a preset value.
Specifically, after determining the historical sequence identity, a difference between the current sequence identity and the historical sequence identity may be determined.
After determining the difference, the difference may be compared to a preset value.
The preset value may be the smallest step for sequence identification, e.g. 1.
Therefore, when the difference value is a preset value, the current resource state information is the resource state information which is sequentially generated after the historical resource state information corresponding to the historical sequence identifier; when the difference is not a preset value (e.g., 2 times the preset value, 3 times the preset value, etc.), it is indicated that at least one resource status information generated before the current resource status information and after the historical resource status information is not synchronized to the control end.
Step 403, executing a jump operation for jumping to update the local cache according to the corresponding current resource state information and the corresponding current sequence identifier to complete synchronization of the current resource state information when the difference value is a preset value.
Specifically, if the difference is the preset value, the step is skipped to "update the local cache according to the corresponding current resource status information and the current sequence identifier" through the skip operation, so as to complete synchronization of the current resource status information.
And step 404, acquiring all resource data of the target resource on the platform under the condition that the difference value is not a preset value, wherein the resource data comprises the corresponding resource state information and the sequence identifier.
Specifically, under the condition that the difference value is not a preset value, all resource data of the target resource on the platform are acquired again to acquire at least one resource state information which is not generated locally at the control end before the current resource state information and after the historical resource state information.
Further, all resource data of each resource on the platform can be obtained so as to supplement lost resource data of all resources.
As shown in fig. 4, according to another aspect of the embodiments of the present application, there is further provided an optional resource status synchronization method, applied to a platform, including the following steps:
step P101, establishing long connection with a control console;
specifically, the console may actively initiate a long connection establishment request to the platform, and after the platform responds to the console, the long connection between the console and the platform may be established.
Step P102, under the condition that the change event of the target resource is determined, generating current resource state information of the target resource, wherein the current resource state information is used for indicating the state of the target resource after the change event.
Specifically, the platform may obtain the change of the underlying resource to determine whether a change event occurs in the target resource.
The target resource may be any resource, for example, any virtual machine that needs to be created, any hard disk that needs to be mounted, and so on.
Under the condition that the platform determines that the change event occurs to the target resource, the latest current resource state information of the target resource after the change event occurs can be generated.
Optionally, the platform may acquire the resource change of the bottom layer in real time, so as to determine whether the target resource has a change event.
And step P103, transmitting the current resource state information to the control console through long connection, so that the control console updates the local cache of the control console according to the current resource state information, and the synchronization of the current resource state information is completed.
Specifically, after the platform generates the current resource state information of the target resource based on the change event, the platform can send the current resource state information to the console through the pre-established long connection, so that the console can acquire the current resource state information.
After the console obtains the current resource status information, the local cache may be updated according to the current resource status information.
Optionally, updating the local cache may be: 1. replacing the local resource state information of the previous cache corresponding to the target resource with the current resource state information; 2. and adding the corresponding relation between the current resource state information and the target resource locally.
After the local cache is updated according to the current resource state information, synchronization of the current resource state information between the console and the platform is completed.
Further, after the synchronization of the current resource status information is completed, the console can directly use the current resource status information in the local cache in the subsequent process of real-time tracking and event notification to the front end.
As an alternative embodiment, as shown in fig. 5, the method as described above, for sending the current resource status information to the console through the long connection, includes the following steps:
step P201, dividing the current resource state information of the target resource and the current sequence identifier corresponding to the current resource state information into a plurality of data blocks, wherein the sequence identifier is used for indicating the time sequence of the resource state information corresponding to the sequence identifier in all the resource state information of the target resource;
step P202, a plurality of data blocks are sent to the console block by block.
Specifically, after the long connection between the console and the platform is created, the console can track the change of the resource state of the target resource in real time, and the long connection is not disconnected, so that the platform can continuously notify the console of the event state.
Alternatively, the implementation of long connections may use Chunked Transfer Encoding of HTTP. This allows the platform to transmit event data to the console in real time by blocking when a new event occurs, without having to close the connection. The bound Encoding allows dividing the current resource status information and the current sequence identifier corresponding to the current resource status information into a plurality of data blocks, wherein each data block is provided with a unique corresponding length prefix, so that the data blocks can be transmitted block by block; and the console can judge whether the received multiple data blocks are complete (namely, whether the received multiple data blocks can be used for recovering to obtain the resource state information and the corresponding sequence identification) based on the length prefix corresponding to each data block, and after the multiple data blocks are determined to be complete, the sequence relation among the data blocks can be determined based on the multiple length prefixes, so that the current resource state information and the current sequence identification can be recovered conveniently.
The platform can send the plurality of data blocks to the console block by block after generating the plurality of data blocks, which ensures real-time and uninterrupted communication of the data transmission after sending to the console.
By using the Chunked Transfer Encoding of HTTP, the platform can transmit corresponding events to the console in real time when the resource changes, and the console can continuously receive event notifications, so as to ensure timely update and synchronization of the resource state information.
Specifically, after the console obtains the current resource status information and the current sequence identifier, the local cache of the console may be updated based on the current resource status information and the current sequence identifier, for example, the current resource status information and the current sequence identifier are added to the local cache, so as to complete synchronization of the current resource status information.
As an alternative embodiment, as the foregoing method, before dividing the current resource status information of the target resource and the current sequence identifier corresponding to the current resource status information into the plurality of data blocks, the method further includes the steps of:
determining a latest historical sequence identifier corresponding to the target resource before a change event occurs; and performing incremental operation on the historical sequence identifier according to a preset value to obtain the current sequence identifier.
Specifically, the platform may determine, before the change event occurs, a latest historical sequence identifier corresponding to the target resource; that is, before the change event occurs, the sequence identifier corresponding to the latest resource status information corresponding to the target resource.
After the historical sequence identifier is determined, the historical sequence identifier can be subjected to incremental operation according to a preset value so as to obtain the current sequence identifier.
For example, in the case where the preset value is 1 and the history sequence is identified as 3, the current sequence is identified as 4.
Further, the sequence identifier may also be used to indicate the corresponding target resource, e.g., the identifier of the target resource is M1, then the sequence identifier corresponding to the target resource may be M1-1 (i.e., the initial sequence identifier of the target resource), M1-2, and so on.
By the method of the embodiment, the current sequence identifier corresponding to each change event, namely, the sequence identifier corresponding to each resource state information can be determined, and the uniqueness of the identifiers can be ensured.
As shown in fig. 6, an application example is provided in which any of the foregoing embodiments is applied:
1. resource scan (Resource Scanning): the console first obtains resource state information for all resources (including target resources) on the current platform locally (Scan operation) through the RESTful API of the platform (i.e., one of the optional target interfaces). At the same time, the platform returns a flag called "sequence" (i.e., sequence identity), which monotonically increases in the global scope, and the console caches the flag locally. For each resource, it is bound to one "sequence" each other.
Thus, after the resource scan is completed, the console will have a local cache of resource status information for all resources on the platform and the "sequence" tag associated therewith.
This allows the console to directly use the resource data (i.e., including the one-to-one resource status information and sequence identification) in the local cache during subsequent real-time tracking of the resource status and event notification to the front-end without having to re-acquire from the platform. The implementation method can more fully utilize the acquired resource data, improves the efficiency and ensures the integrity of the resource state.
2. Real-time Tracking: the console tracks changes in resource status in real time (Track operations) by establishing long connections with the platform. This long connection is not broken to ensure continued event notification.
The implementation of long connections may use Chunked Transfer Encoding of HTTP. This allows the platform to transmit event data to the console in real time by blocking when a new event occurs, without having to close the connection. The bound Encoding allows the data to be divided into a plurality of data blocks, each data block having its own unique corresponding length prefix, so that it can be transmitted block by block; and the control console can recover the current resource state information and the current sequence identifier based on the length prefix corresponding to each data block. This ensures real-time and uninterrupted communication of data transmissions.
By using the Chunked Transfer Encoding of HTTP, the platform can transmit corresponding events to the console in real time when the resource changes, and the console can continuously receive event notifications, so as to ensure timely update and synchronization of the resource state information.
3. Event notification (Event Notification): whenever a target resource (i.e., any one of all resources) of the platform changes (e.g., adds, deletes, updates, etc.), the platform sends the corresponding resource status and operation (i.e., resource status information) of the target resource to the console over the long connection. Meanwhile, the platform increases the sequence corresponding to the target resource to obtain the current sequence identifier, and sends the current resource state information and the current sequence identifier to the console.
4. Local cache update (Local Cache Update): and the console updates the local resource cache according to the received resources and the operation, and executes corresponding processing according to the operation type. This ensures that the resource states between the console and the platform remain synchronized.
Message reliability assurance:
when a network outage occurs or an out-of-order request occurs, the console will detect whether data is lost by comparing the difference between each received "sequence" and the last round of buffered "sequence". If the difference is greater than 1, the console will perform a "Scan" operation to re-acquire the full amount of data resources of the platform to ensure the reliability of the message. This is similar to an optimistic lock mechanism to ensure reliability of the message.
