Description

Inter-process communication method based on vehicle-mounted equipment and related equipment
Technical Field
The invention relates to the technical field of data transmission, in particular to an inter-process communication method based on vehicle-mounted equipment and related equipment.
Background
IPC (Inter-Process Communication ) refers to the interaction that occurs between the data of two processes. On the vehicle-mounted equipment, a plurality of APP often need to interact with each other, and traditional IPC modes comprise Binder, broadcasting, socket and the like, but under the condition that the chip performance of the vehicle-mounted equipment is difficult to be as excellent as high-tip equipment such as a mobile phone and the like, the IPC schemes have certain limitations.
Aiming at Binder, the method is a high-performance IPC communication mode, but the framework is a C/S framework, so that one-to-many communication can only be realized, namely a service end and N clients are difficult to realize in the situation of many-to-many communication or cross-device communication. While data may be transmitted globally or individually to an application by broadcast, this is difficult to achieve for a specific number of apps globally, such as the broadcast from a in fig. 2, either all received through global, B, C and D, or only one of notification A, B or C, and no transmission to a and B can be achieved. Socket is a very common communication mode, and is commonly used for communication between a client and a server, and if Socket is directly used in an App, a huge burden is caused to the whole vehicle-mounted device. Each App is used as a server, although data transmission can be realized, the Cpu occupation of the IO in the vehicle-mounted device may be high, and for the vehicle-mounted device with limited manufacturing cost, the load is difficult, so that Socket realization can only be used as a secondary option.

As shown in fig. 3, the present embodiment provides an inter-process communication method based on a vehicle-mounted device, for convenience of description, the vehicle-mounted device is used as an execution subject, and the inter-process communication method based on the vehicle-mounted device includes the following steps:
s10, obtaining the message to be sent and the service name.
Specifically, the inter-process communication mainly sends a message from one end to the other end, for convenience of explanation, one end sending the message is a client (client), and one end receiving the message is a service. In this embodiment, the client starts with a message sent by the client, and the client first obtains the message to be sent and the expected service name. The service name may be in a "trs:// service alias" format.
One service terminal may correspond to a plurality of service names, and at the same time, one service name may correspond to a plurality of service terminals. The same message corresponds to different service names, and the sent objects can be one or more, and one-to-one or one-to-many sent messages can be realized based on the service names during subsequent sending.
S20, determining a service end corresponding to the service name and a service address corresponding to the service end according to the service name.
Specifically, the service name only provides the type of service, determines different numbers of service ends corresponding to a message, and requires the actual location of the service ends when actual communication is performed. Therefore, it is first necessary to determine, according to the service name, the service end capable of providing the service for the client and the service address corresponding to each service end.
In one implementation, the manner of determining the service end with the service name is listed in the form of an array, for example, the service name 1 corresponds to the service end 1 and the service end 2, and addresses of the service name, the service end and the service end are written into the array, and these arrays can be recorded in a routing table, and the service end corresponding to the service name is determined by traversing the routing table.
But traversing is inefficient when the number of service names and servers is large. Therefore, in the second mode of searching for the service end and the address thereof corresponding to the service name, firstly, according to the service name, the label serial number corresponding to the service name is searched, the label serial number can be letters such as a, b or the like, or can be a number, and then, according to the label serial number, the routing table is quickly searched, so that the service end corresponding to the service name and the service address corresponding to the service end are obtained. The marking serial number represents the storage position of the service end and the address corresponding to the service name, so that relatively, when the service end and the service address are recorded, a plurality of service ends and the address storage positions corresponding to the individual service names are marked by the marking serial number, the marking serial number and the service names are mapped, and the mapping mode can be through a fixed algorithm or a data table, so that the routing table can be quickly found only by the marking serial number without traversing. The efficiency of determining the service end and the service address is greatly improved.
Further, for inter-process communication, because different processes are all located on the same host, the service address corresponding to the server is not a conventional IP address, but a socket file address is adopted, the socket file is an interface for connecting the server and the client, and the address of the server can also be determined by locating the interface of the server. The address format may refer to "file:// socket filename". In addition, for communication between different hosts, different service addresses can be determined according to the communication protocol, for example, the TCP/IP protocol is taken as an example, and the service end address can refer to 'TCP:// IP address: port number'.
Further, when the service address corresponding to the service end is changed, for example, based on the change of the socket caused by the update of the service end, the service end may first send an address change instruction to the client, where the address change instruction includes the address before update that needs to be changed. And finding a corresponding service address in a routing table through the address before updating, and updating the service address according to the address after updating in the address changing instruction. Because a service address may correspond to a plurality of service names, the service address is stored for a plurality of times, when updating, the service address can be searched for at the service end corresponding to the service name, and when the searched service address is the same as the address before updating, the updated address replaces the original service address, thereby reducing the time of independent updating.
S30, judging whether the service end is located in the local machine or not according to the service address.
Specifically, because of the obvious difference between the inter-process communication and the communication between different hosts, the service address can determine whether the server side receiving the message is located in the same host according to the service address, i.e. the server side and the client side are located in the same host, and the method belongs to the inter-process communication. If the server is not located in the host, the server and the client belong to different hosts, and message transmission between the server and the client belongs to communication between the hosts.
And S40, if the server is located in the local, generating a first socket file and a second socket file according to the information and the service address for each server, and establishing first data connection with the server.
Specifically, if the server is located in the local, the inter-process communication is required subsequently. For each server needing communication, generating a first socket file and a second socket file according to a message to be sent, wherein the first socket file is directly generated according to the message, and has a mounting function, namely, the message is mounted to a buffer area of a socket for subsequent transmission, and the second socket file is created based on the server and is used for subsequently transferring the content of the buffer area of the first socket file to the server. Meanwhile, based on the known service address, a first data connection is established between the client and the server for subsequent communication.
Further, in order to ensure the safety and rapidness of the message in the message transmission process, in this embodiment, when the server side is judged to be located in the local, the message is serialized first to obtain the sequence information. And then generating a first socket file and a second socket file according to the sequence information and the service address. After receiving the sequence information, the server performs reverse sequence processing on the sequence information by using a contracted reverse sequence method to obtain an original message. The manner of serialization may include Protobuf serialization.
Further, in the aspect of generating the first socket file and the second socket file, firstly, a socket template file of a client is obtained, and sequence information is loaded to a cache region of the socket template file to obtain the first socket file. Meanwhile, a service address is added on the basis of the socket template file, and a second socket file corresponding to the service end is obtained. Because the second socket file contains the service address, the second socket file can be transmitted to the server based on the first data connection.
S50, associating the first socket file with the second socket file, and adding the second socket file into a receiving queue of the server based on the first data connection so as to realize transmission of the message.
Specifically, the first socket file and the second socket file are associated, so that information of a buffer area of the first socket file is transferred to the second socket file, the second socket file is added into a receiving queue of a server based on the created first data connection, and when the server starts a recv () method to start receiving the file, information is extracted from the second socket file, so that information transmission is realized.
In addition, as shown in fig. 4, if the server is not located locally, the scheme may also use other network protocols for data transmission. Firstly, establishing second data connection with a service end according to a service address, searching a third socket file corresponding to the service address according to the service name, and loading a message into a buffer area of the third socket file to obtain transmission data. And finally, based on the second data connection, transmitting the transmission data to a receiving queue of the server side so as to realize the transmission of the message.
According to the scheme, firstly, through the service names, a plurality of corresponding service ends and addresses thereof can be determined, and when in transmission, corresponding data connection and socket files can be created for each service end, so that message transmission based on socket and data is realized. Therefore, in the scheme, one-to-many, even many-to-many inter-process communication can be realized, and the high-performance requirement on a chip is not needed, so that the method is suitable for being applied to vehicle-mounted equipment.
