Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

FIG. 1 is a flowchart of an embodiment of a multi-process communication method according to the present invention. As shown in FIG. 1 , the multi-process communication method according to the embodiment of the present invention is applied to the transfer process of the IOS side, including:

S101 , a transfer process is established, and according to a communication protocol, a listening port corresponding to the transfer process is established, and the listening port is used for data communication with at least one application process.

The system will allocate a process for the started software, such as a transfer process and an application process. The transfer process communicates data with at least one application process, that is, cross-process communication. The user spaces of the processes are independent of each other and generally cannot access each other. Inter-process communication is to spread or exchange information between different processes. Since data cannot be synchronized between processes on the IOS side in time, a listening port corresponding to the transit process is established according to the communication protocol, and data communication is performed with at least one application process through the listening port. Each process may correspond to the same application software, or may correspond to different application software. When data is updated in a process (or when a certain task is completed, data is added, deleted, or modified, or data is queried), the relevant information needs to be synchronized to the transfer process first, and the listening port of the transfer process receives the relevant information.

S102: Receive first data sent by a first application process through a corresponding first application port through a listening port, and perform a service operation according to the first data.

As an example, the first data may be data and instructions that need to be updated. For example, the first application process is a process of registering a user account. When the user completes account registration, the first application process needs to pass the user name and password of the registered user through the first application process. The port is synchronized to the transfer process. After the listening port of the transfer process receives the user name and password, the user name and password are written into the database.

The multi-process communication method provided by the embodiment of the present invention is applied to the relay process on the IOS side, establishes a monitoring port corresponding to the relay process, and receives data sent by the process through the monitoring port, so that the iOS terminal can synchronize the process data in time.

Further, on the basis of the above method embodiments, it may also include: synchronizing the first data to the second application process through the listening port, at least one application process includes the second application process, and the second application process passes the corresponding second application process. The application port receives the data; and/or updates the data in response to the transfer process, synchronizes the updated second data to the first application process through the listening port, and the first application process receives the data through the corresponding first application port; and/or In response to the transfer process updating the data, the updated second data is synchronized to the second application process through the listening port.

The first/second application process is the same IOS-side process. After the intermediate process receives the first data of the first application process, it can synchronize the first data to the second application process; similarly, after the intermediate process updates the data, The updated second data may also be synchronized to other processes.

Further, on the basis of the above method embodiments, establishing a transfer process includes: installing a NetworkExtension plug-in, and establishing a transfer process by starting the plug-in.

The NetworkExtension plugin contains a collection of APIs for customizing and extending core networking functionality in iOS and macOS. It can set the password and label (subtitle) for the WiFi list in the system to directly click to connect. Also get the entire WiFi list. Customize and expand the API set of core network functions through the NetworkExtension plug-in, and implement a lightweight C-S architecture model on the iOS mobile phone, that is, through the transfer process, to complete the communication between other application software processes.

Further, on the basis of the foregoing method embodiments, the communication protocol may include the WebSocket protocol.

WebSocket is a protocol for full-duplex communication over a single TCP connection. Transmission Control Protocol/Internet Protocol (TCP/IP for short). Communication between processes is based on the WebSocket protocol.

As shown in FIG. 3 , which is a schematic diagram of an application scenario of the overall structure and logic of the present invention in a zero trust scenario, Zero Trust (Zero Trust, ZT for short) provides a series of concepts and ideas, assuming that the network environment has been Under the premise of compromise, when each access request in information systems and services is executed, the uncertainty of its decision-making accuracy is reduced. Zero Trust Architecture (ZTA) is a plan for enterprise network security. It is based on the concept of zero trust and is built around its component relationships, workflow planning and access policies. In Figure 3, a transit process is created based on the WebSocket protocol. The server process is denoted as the S end, the first application process is the Client1 process, which is denoted as the C1 end, and the second application process is the Client2 process, which is denoted as the C2 end. First, the Server service of WebSocket started by the NetworkExtension plug-in, and the C1 or C2 side of WebSocket started by the application (Application, app for short), when the S side (subject) accesses the C side (object), it needs to establish a link, send Data, the S terminal operates the process according to the data information. For another example, in zero trust, in the process of MFA authentication (or other multi-identity source scenarios, multi-factor authentication scenarios), after completing MFA on the C1 or C2 end, the S end does not know, and needs to send data to the S end. Let the S side complete the data refresh and synchronize the data.

As shown in FIG. 4 , it is a schematic diagram of an application scenario in which a transfer process synchronizes data to other processes in a zero-trust scenario. In zero trust, the S side will have a strong demand to notify the C1 side or the C2 side when it receives the Topic notification. Therefore, in this scenario, it will notify the client (ie, the C1 side or the C2 side) through WebSocket. When there are multiple application processes linked to the transfer process, the transfer process can be easily notified to all application processes through WebSocket, which greatly improves the efficiency of cross-process communication.

FIG. 2 is a flow chart of other embodiments of the multi-process communication method of the present invention. As shown in FIG. 2 , the multi-process communication method according to the embodiment of the present invention, applied to the application process of the IOS side, includes:

S201 , according to the communication protocol, establish at least one application port corresponding to at least one application process, and the at least one application port is used for data communication with the transfer process.

In some embodiments, the communication protocol between the relay process and the at least one application process may be a pipe, which is characterized as half-duplex, ie, data cannot be transmitted in both directions at the same time. Some systems may support full duplex. Only between parent and child processes. The classic form is that the pipe is created by the parent process, and after the process forks the child process, it can be used between the parent and child processes. The communication protocol can also be a message queue, a semaphore, a shared memory, a network socket, etc., which can be set as needed.

S202, in response to the first application process in the at least one application process updating the data, synchronize the updated first data to the transfer process through the first application port corresponding to the first application process, and the transfer process receives the data through the corresponding listening port .

As an example, the first data may include data and instructions that need to be updated. For example, the first application process is a process for registering a user account. When the user completes account registration, the first application process needs to pass the user name and password of the registered user through the first application process. The port is synchronized to the transfer process. After the listening port of the transfer process receives the user name and password, the user name and password are written into the database.

The multi-process communication method provided by the embodiment of the present invention is applied to the application process of the IOS side, and at least one application process synchronizes data with the transfer process through at least one application port, thereby realizing data synchronization between at least one application process.

Further, on the basis of the above method embodiments, at least one application process includes a second application process, and the method further includes: receiving, through a second application port corresponding to the second application process, the first data sent by the transit process through the listening port and/or the first application process receives the second data sent by the transfer process through the monitoring port through the first application port, and carries out business operations according to the second data; and/or the second application process receives the transfer process through the second application port by monitoring The second data sent by the port is used to perform service operations according to the second data.

Between the various processes on the IOS side, data synchronization can be completed through the transfer process, and tasks issued by the transfer process can also be executed to perform business operations, such as querying data and verifying.

Further, on the basis of the above method embodiments, the communication protocol includes the WebSocket protocol.

The present invention can implement a lightweight C-S architecture model on the IOS mobile phone terminal, hereinafter referred to as the first application process process is the C1 process, the second application process process is the C2 process, and the transfer process is the S process.

In dealing with one-to-one cross-process communication scenarios. Start a WebSocket S-side (ie server) through the Server process, and create a WebSocket C1 client in the C1 process to link the S-side of the Server process to realize the C1-S efficient cross-process full-duplex communication mechanism;

In dealing with one-to-many cross-process communication scenarios. Start a WebSocket S-side through the Server process, create a WebSocket C1 client in the Client1 process to link the S-side of the Server process, and create a WebSocket C2 client in the Client2 process to link the S-side of the Server process to achieve C1 -S/C2-S efficient cross-process full-duplex communication mechanism;

In dealing with many-to-many cross-process communication scenarios. Start a WebSocket S-side through the Server process, create a WebSocket C1 client in the Client1 process to link the S-side of the Server process, and create a WebSocket C2 client in the Client2 process to link the S-side of the Server process. end as a relay. A C1-S/C2-S/C1-S-C2 efficient cross-process communication mechanism for multi-terminal communication.

When multi-process data is synchronized, the data can be sent from the C side to the S side through the WebSocket link between the C and S, and the operations required for data synchronization are completed on the S side.

In zero trust, after the C-side login is completed, if the synchronization of the login situation needs to be completed on the S-side, the Token generated during the login process is generally passed to the S-side, and the login is completed on the S-side. Through WebSocket, it can be easily Synchronize login status.

In Zero Trust, when the login status of the C-side or the application data changes, the login data can be synchronized to the S-side through the WebSocket link between the C-S and the S-side. The S-side can perform corresponding business operations according to the data change scenarios, such as immediately from the gateway. Refresh data.
