Detailed Description
It is noted that the terminology used in the description of the embodiments of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application. In the description of the embodiments of the present application, "/" means "or" unless otherwise specified, for example, a/B may mean a or B; "and/or" herein is merely an associative relationship describing an association, meaning that there may be three relationships, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality" means two or more, and "at least one", "one or more" means one, two or more, unless otherwise specified.
In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a definition of "a first" or "a second" feature may explicitly or implicitly include one or more of the features.
Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.
The execution main body of the data cross-process sharing method provided by the embodiment of the application can be terminal equipment. Illustratively, the terminal device may be an electronic device such as a mobile phone, a tablet computer or a notebook computer.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a terminal device according to an embodiment of the present disclosure. As shown in fig. 1, the terminal device may provide a process management service 11, a data storage management service 12, and the like.
The process management service 11 is specifically configured to provide services such as process registration, process monitoring, and processing and/or responding to a request initiated by a process.
Specifically, before a certain process is run for the first time by the terminal device, the process needs to be registered (i.e., created) in the process management service 11. When the terminal device registers a process in the process management service 11, the process management service 11 determines whether the process requested to be registered by the terminal device is a process allowed by the process management service 11.
If the process management service 11 determines that the process requested to be registered by the terminal device is the process allowed by the terminal device, the process management service 11 registers the process and allocates a token for proving the identity of the process to the process after the process is successfully registered.
In one possible implementation, when the terminal device registers a process in the process management service 11, the terminal device may provide the process management service 11 with an identity of the process requesting registration. Illustratively, the identity of the process may include the name or address of the process, etc. Based on this, the token may be generated by the process management service 11 by using a preset encryption policy based on the identity of the process requesting registration and the validity period of the token.
The limited period of the token may be obtained by the process management service 11 according to the first time when the process registration is successful and the preset time length. The preset duration can be set according to actual requirements, and is not limited here. Specifically, the process management service 11 may use a first time as a start time, obtain an end time according to the first time and a preset time length, and describe the validity period of the token by the start time and the end time.
After the process registration is successful, the process management service 11 may monitor the process. E.g., whether the listening process initiated a data processing request, etc. For example, if it is monitored that a process initiates a data processing request, the process management service 11 may process the data to be processed based on the data processing request. Thereafter, the process management service 11 may return the data processing result to the process.
The data storage management service 12 is specifically for providing storage management services for shared data. Shared data refers to data that can be shared between different processes, and shared data can be created by different processes. The data storage management service 12 may store all the shared data created by different processes in the shared memory 13 for unified management, so that each process may obtain the required shared data from the shared memory 13. Illustratively, the shared memory 13 may be a physical memory in the terminal device.
To distinguish between shared data, the data storage management service 12 may identify each shared data stored in the shared memory 13, i.e., different shared data may have different identifications in the shared memory 13. When a process acquires certain shared data from the shared memory 13, the process may also identify the shared data, and different processes may identify the same shared data differently. That is, the same shared data has different identifications in the shared memory 13 and in different processes.
By way of example and not limitation, the identification of the shared data may be a Uniform Resource Identifier (URI) of the shared data.
In this embodiment, the terminal device may perform associated storage on the identifier of the shared data in each process and the identifier of the shared data in the shared memory 13. That is, the terminal device may store a corresponding relationship between the identifier of the shared data in the shared memory 13 and the identifier of the shared data in each process. For example, the terminal device may store a corresponding relationship between an identifier of the shared data in the shared memory 13 and an identifier of the shared data in the first process. Or the terminal device may store a corresponding relationship between the identifier of the shared data in the shared memory 13 and the identifier of the shared data in the second process.
Referring to fig. 2, fig. 2 is a schematic flowchart of a data cross-process sharing method according to an embodiment of the present application. The data cross-process sharing method can comprise S201 to S204, which are detailed as follows:
s201: receiving a data processing request from a first process, wherein the data processing request carries a first token, a first identifier of target shared data to be processed and a target data processing strategy of the target shared data.
In this embodiment of the application, the terminal device may invoke the process management service to execute S201, that is, the process management service may receive the data processing request from the first process.
The first process may be any process running in the terminal device.
When the first process needs to query or update the target shared data, the first process may initiate a data processing request for the target shared data to the process management service. The data processing request may carry a first token, a first identifier of the target shared data, and a target data processing policy for the target shared data.
The target shared data may be shared data created by the first process, or shared data created by other processes except the first process, and is not limited herein.
The first token may be assigned by the process management service to the first process after the registration is successful. Alternatively, the first token may be obtained by the first process from another place, which is not limited herein.
The first identifier of the target shared data refers to an identifier of the target shared data in the shared memory.
By way of example and not limitation, the first process may initiate a data processing request to the process management service by calling an Application Programming Interface (API).
In this embodiment of the application, the data processing request may include: data query requests, data update requests, and the like. The data update request may include: data modification requests, data deletion requests, data write requests, and the like.
In a possible implementation manner, when the data processing request is a data query read request, the target data processing policy carried in the data processing request may specifically be a data query policy. For example, the data query policy may be: querying the target shared data from the first process based on the first identification of the target shared data; and if the query target shared data does not exist in the first process, querying the target shared data from the shared memory based on the first identifier of the target shared data.
In another possible implementation manner, when the data processing request is a data modification request, the target data processing policy carried in the data processing request may specifically be a data modification policy. For example, the data modification policy may be: and modifying the value of the first field of the target shared data into the target value.
In another possible implementation manner, when the data processing request is a data deletion request, the target data processing policy carried in the data processing request may specifically be a data deletion policy. For example, the data deletion policy may be: deleting the target shared data; or delete the target field of the target shared data, etc.
In another possible implementation manner, when the data processing request is a data write request, the target data processing policy carried in the data processing request may specifically be a data write policy. For example, the data write strategy may be: writing the target shared data into the shared memory; or adding a target field in the target shared data, and the like.
S202: and performing identity verification on the first process based on the first token.
In this embodiment of the application, the terminal device may invoke the process management service to execute S202, that is, the process management service may perform identity verification on the first process based on the first token carried in the data processing request.
The token distributed by the process management service for the process is generated by adopting a preset encryption strategy based on the identity of the process and the validity period of the token. Therefore, in an embodiment of the present application, the data processing request may also carry an identity of the first process; s202 may specifically include the following steps:
analyzing the first token based on a preset decryption strategy to obtain the validity period of the first token and the identity of a process;
and if the current time is within the validity period and the identity of the process obtained by analysis is the same as the identity of the first process carried in the data processing request, confirming that the identity verification is successful.
The preset decryption strategy is a decryption strategy corresponding to the preset encryption strategy.
The current time refers to the time when the process management service receives a data processing request from the first process.
In this embodiment, after the process management service analyzes the first token, it may be determined whether the current time is within the validity period of the first token obtained through analysis.
In a possible implementation manner, if the current time is within the validity period of the first token, it indicates that the first token is currently valid, and at this time, the process management service determines whether the identity of the process obtained through the analysis is the same as the identity of the first process carried in the data processing request. In one case, if the identity of the process obtained through the analysis is the same as the identity of the first process carried in the data processing request, the process management service determines that the identity verification of the first process is successful, that is, the first process is a process registered in the process management service. In another case, if the identity of the process obtained through the analysis is different from the identity of the first process carried in the data processing request, the process management service determines that the identity verification of the first process fails, that is, the first process is not a process registered in the process management service.
In another possible manner, if the current time is not within the validity period of the first token, it indicates that the first token is expired currently, and at this time, the process management service determines that the identity check on the first process fails.
In this embodiment, if the identity verification of the first process is successful, the terminal device may execute S203.
S203: and if the identity verification is successful, searching the target shared data from the shared memory based on the first identifier, and processing the target shared data based on the target data processing strategy.
In this embodiment of the application, the terminal device may invoke the process management service and the data storage management service to execute S203.
Specifically, in an embodiment of the present application, if the identity verification of the first process is successful, the process management service may directly search the target shared data from the shared memory based on the first identifier of the target shared data. In one possible case, if the process management service can find the target shared data from the shared memory (i.e., the shared memory stores the target shared data), the data storage management service can process the target shared data based on the target data processing policy. In another possible case, if the process management service cannot find the target shared data from the shared memory (i.e., the shared memory does not store the target shared data), the process management service may return the first prompt message to the first process. The first prompt message is used for prompting that the first process target shared data does not exist.
In another embodiment of the present application, if the identity verification of the first process is successful, the terminal device may execute S2031 to S2033 shown in fig. 3, which are detailed as follows:
s2031: determining a second identification of the target shared data in the first process based on the first identification.
S2032: and judging whether the target shared data is included in the first process or not based on the second identification.
S2033: and if the first process comprises the target shared data, processing the target shared data in the first process based on the target data processing strategy, and synchronizing the processed target shared data into the shared memory.
In this embodiment, the terminal device may invoke the process management service to execute S2031 to S2032, and invoke the process management service and the data storage management service to execute S2033.
Specifically, if the identity of the first process is successfully checked by the process management service, the process management service may determine, based on a first identifier of the target shared data and a correspondence between an identifier of each piece of shared data, which is stored in advance in the terminal device, in the shared memory and an identifier of each piece of target shared data in the first process, a second identifier of the target shared data in the first process.
After the process management service determines the second identifier of the target shared data in the first process, it may determine whether the first process includes the target shared data based on the second identifier. In one possible case, if the process management service can find the target shared data from the first process based on the second identifier, the process management service determines that the target shared data is included in the first process. In another possible case, if the process management service cannot find the target shared data from the first process based on the second identifier, the process management service determines that the target shared data is not included in the first process.
In a possible implementation manner, if the first process includes the target shared data, the data storage management service may process the target shared data in the first process based on the target data processing policy, and synchronize the processed target shared data to the shared memory.
In another possible implementation manner, if the first process does not include the target shared data, the terminal device may execute S2034 to S2035 shown in fig. 3, that is, after S2032, the method for sharing data across processes may further include S2034 to S2035, which is detailed as follows:
s2034: and if the target shared data is not included in the first process, judging whether the shared memory stores the target shared data or not based on the first identifier.
S2035: and if the target shared data are stored in the shared memory, processing the target shared data stored in the shared memory based on the target data processing strategy.
S2036: and if the target shared data is not stored in the shared memory, returning first prompt information to the first process, wherein the first prompt information is used for prompting that the target shared data does not exist.
In this embodiment, if the first process does not include the target shared data, the process management service may determine whether the shared memory stores the target shared data based on the first identifier of the target shared data.
In a possible case, if the process management service determines that the target shared data is stored in the shared memory, the data storage management service may process the target shared data stored in the shared memory based on the target data processing policy. In another possible case, if the process management service determines that the target shared data is not stored in the shared memory, the process management service may return first prompt information to the first process to prompt that the target shared data does not exist in the first process.
S204: and synchronizing the processed target shared data to each target process, wherein the target process is a process which acquires the target shared data, and the target process comprises the first process.
In this embodiment of the application, the terminal device may invoke the data storage management service to execute S204, that is, the data storage management service may synchronize the processed target shared data to each process that has acquired the target shared data. The process of acquiring the target shared data may include the first process and any other process except the first process.
In a possible implementation manner, if the terminal device executes the step S2033 (i.e. processes the target shared data in the first process), the data storage management service may not synchronize the processed target shared data stored in the shared memory to the first process.
In another possible case, if the terminal device does not execute S2033, but directly processes the target shared data stored in the shared memory, the data storage management service needs to synchronize the processed target shared data stored in the shared memory to the first process.
As can be seen from the above, in the method for sharing data across processes provided in this embodiment, because the data processing request initiated by the first process carries the first token, and when the data processing request initiated by the first process is received, the identity of the first process is verified based on the first token, and after the identity is successfully verified, the target shared data stored in the shared memory is processed based on the target data processing policy carried in the data processing request, that is, the target shared data is processed only when the first process has the right to process the target shared data, so that the security of the shared data is improved; after the target shared data is processed, the processed target shared data is synchronized to each process which acquires the target shared data, so that the consistency of the target shared data in different processes is ensured, and the atomicity of the target shared data is improved.
Referring to fig. 4, fig. 4 is a schematic flowchart of a data cross-process sharing method according to another embodiment of the present application. As shown in fig. 4, the difference between this embodiment and the embodiment corresponding to fig. 2 is that this embodiment may further include S205 after S202, which is detailed as follows:
s205: and if the identity verification fails, returning second prompt information to the first process, wherein the second prompt information is used for prompting that the first process does not have the authority for processing the target shared data.
In this embodiment, the terminal device may invoke the process management service to execute S205, that is, if the identity verification of the first process fails, the process management service may return the second prompt message to the first process to prompt that the first process has no authority to process the target shared data.
