In the embodiment of the invention, the cross-process data transmission method can be applied to a cross-process data transmission system, wherein the cross-process data transmission system comprises a software application end, a local service end and a data providing end.

As shown in fig. 1, the cross-process data transmission method provided by the embodiment of the invention specifically includes the following steps:
s101, when receiving a data transmission instruction, the software application terminal generates data transmission request information according to the data transmission instruction and sends the data transmission request information to a local server terminal through inter-process communication.
In this embodiment, the data transmission instruction is specifically understood as an instruction inputted from the outside for determining whether data transmission is required or controlling the start and stop of data transmission. The data transmission request information may be specifically understood as generated after the localization processing of the real network address, and includes the required real network address information and other information for determining whether the data transmission is required.
Specifically, when receiving a data transmission instruction, the software application terminal judges the specific type of the data transmission instruction, processes the real network address aiming at the instruction needing to carry out data transmission so as to be suitable for interprocess communication with the local server terminal, synthesizes the processed network address and information used for representing the data transmission need to generate data transmission request information, and then sends the data transmission request information to the local server terminal through interprocess communication by the software application terminal.

Because the local server is a server playing a role in forwarding, in order to better interface with the data providing end under the real network address, the local server needs to be configured according to the real network address contained in the data transmission request information, and the configured local server sends the data transmission request information to the data providing end.
In the embodiment of the invention, the local server which can communicate with the software application end between local processes is directly constructed in the system, so that the software application end and the data providing end which cannot be directly accessed by the real network address are communicated through the local server, an external server is not required to be introduced, the data flow consumption in the data transmission process is reduced, and the data transmission safety and the data transmission efficiency are improved.
S103, the data providing end returns the request data corresponding to the data transmission request information to the local server end, and the local server end returns the request data to the software application end through inter-process communication.
Specifically, after receiving the data transmission request, the data providing end returns the request data corresponding to the data transmission request to the local server end, and further returns the request data to the software application end through inter-process communication between the local server end and the software application end, so that the software application end can realize the transmission and the call of the data in the data providing end which cannot be directly accessed.
According to the technical scheme, when a software application end receives a data transmission instruction, data transmission request information is generated according to the data transmission instruction, and the data transmission request information is sent to a local server end through inter-process communication; the local server analyzes the data transmission request information, if the data transmission request information contains a preset data acquisition identifier, the local server is configured according to the data transmission request information, and the data transmission request information is sent to the data providing end; the data providing end returns the request data corresponding to the data transmission request information to the local server end, and the local server end returns the request data to the software application end through inter-process communication. By adopting the technical scheme, before the cross-process data transmission is carried out, a cross-process data transmission system comprising a software application end, a local service end and a data providing end is constructed, through the local service end and an inter-process communication function arranged between the system, when the software application end receives a data transmission instruction, the data transmission request information can be sent to the data providing end when the data transmission request information is analyzed by the local service end and contains a preset data acquisition identifier, the data provided by the data providing end is further returned to the software application end needing the data through the local service end, the data transmission request transfer between the software application end and the data providing end which cannot be communicated is realized through the local service end and the inter-process communication technology built between the system without adding a third party application, the management authority is not required to be provided for the software application end, the security hole caused by the direct lifting of the authority of an application layer is not required to be increased, the cross-process transmission of the data is realized under the condition that more flow is not required, the logic of the data cross-process transmission is simplified, and the stability of the data transfer is improved when the software application is carried out.
Example two
Fig. 2 is a flowchart of a cross-process data transmission method provided by a second embodiment of the present invention, where the technical solution of the embodiment of the present invention is further optimized based on the above-mentioned alternative technical solutions, and by penetrating an inter-process communication server and an inter-process communication client in a local server and a software application, respectively, before a software application receives a data transmission instruction, and constructing a communication connection between the inter-process communication server and the inter-process communication client, so as to implement communication between the software application and the local server. Meanwhile, a local proxy server is established in the software application end, so that the local proxy server is suitable for transmitting a real network address to the local server, when the software application end receives a data transmission instruction, the address configuration of the data transmission port and the generation of data transmission request information for requesting data are completed or the generation of the data transmission request information for stopping data transmission is completed according to the instruction type of the data transmission instruction, the software application end and the local server can perform proper address configuration when data transmission is required, resource release can be completed as soon as possible when data transmission is not performed, the efficiency and the stability of data transmission across processes are improved, the logic of data transmission across processes is simplified, and the stability of software application when data call is performed is improved.
As shown in fig. 2, the cross-process data transmission method provided by the embodiment of the invention specifically includes the following steps:
s201, an inter-process communication server is created in a local server according to a preset inter-process communication name.
In this embodiment, the preset interprocess communication name may be specifically understood as a name preset according to actual situations, which is used to perform personalized identity representation on the constructed interprocess communication (Unix Domain Socket, UDS). For example, assuming that media data is acquired and played, that is, the data requirement corresponding to the software application end is provided by the MediaPlayer, the inter-process communication name may be set to "MediaPlayerUDS", or the corresponding inter-process communication name may be preset according to the actual situation, which is not limited in the embodiment of the present invention.
Specifically, before the cross-process data transmission system is put into use, a local server Native Service can be pulled up locally in the system, then an inter-process communication Service end LocalServerSocket supporting UDS in android Native is created by taking a preset inter-process communication name as a parameter at the local server, and then an accept method of the LocalServerSocket can be called in a sub-thread, and connection of a client corresponding to the inter-process communication Service end is waited in a blocking mode.
S202, creating an inter-process communication client in the software application according to the preset inter-process communication name.
Specifically, before the cross-process data transmission system is put into use, and after the inter-process communication server is established in the local server, an inter-process communication client LocalSocket supporting UDS in the android native manner can be correspondingly established in the software application according to a preset inter-process communication name which is the same as the name of the inter-process communication server.
S203, the software application end determines a socket address according to the preset inter-process communication name and the preset address creation instruction, and transmits the socket address to the inter-process communication client end so as to complete communication connection between the inter-process communication client end and the inter-process communication server end.
Specifically, after the software application end completes the creation of the inter-process communication client, as the inter-process communication client and the inter-process communication server have the same preset inter-process communication name, the corresponding relationship between the inter-process communication client and the inter-process communication server can be built according to the pre-process communication name, and further, the software application end can use a preset address creation instruction preset in an android system as parameters to create a socket address under a Unix domain socket abstract namespace supporting USD, and further, the socket address is transferred to the inter-process communication client, so that the inter-process communication client can call a corresponding connet method by taking the socket address as the parameters, and the communication connection between the inter-process communication client and the inter-process communication server is completed. Alternatively, wherein the preset address creation instruction may be
The created socket address may be denoted LocalSocketAdress.
S204, creating a local proxy server in the software application.
In this embodiment, the home agent server may be specifically understood as a socket that is established locally and adapted to a local network address, and is used to monitor a client that needs to request data, and may be connected to other servers.
Specifically, in order to perform data request and data transmission when the local proxy needs to perform the request from the real network address, the server socket under the local HTTP protocol needs to be set up at the software application end, and the created server socket is determined as the local proxy server.
S205, binding the local proxy server to preset local domain name and preset idle port number.
In this embodiment, the preset local domain name may be specifically understood as a domain name of a preset local network IP address. The preset idle port number may be specifically understood as a preset idle port number.
For example, assuming that the local IP address is "127.0.0.1" and the preset idle port number is 9090, the constructed local proxy server may be bound to the local IP address and the preset idle port number, and further may block a data transmission request of the MediaPlayer that provides the data requirement by calling the accept method of ServerSocket in the sub-thread.
S206, generating a local network address according to the preset local domain name, the preset idle port number and the preset real network address.
In this embodiment, presetting the real network address can be understood specifically as pre-configuring according to the call requirement of the software application, and storing the real network address of the data to be called in the data providing terminal.
In view of the above, it is assumed that in the usage scenario of the automobile data recorder, the software application end is video playing software that needs to acquire video data, the preset REAL network address is the address of the album in the electronic controller, which may be represented as dvr_real_mp4_path, and then the domain name in the preset REAL network address may be replaced by the preset local domain name "127.0.0.1", and the port number of the preset REAL network address may be replaced by the preset idle port number 9090 used by the local proxy server.
S207, initializing the data transmission port, and monitoring the initialized data transmission port by the local proxy server.
Specifically, after the construction for the inter-process communication between the software application end and the local server end is completed, and the configuration of the local proxy server end is performed, the software application end can be considered to be used for receiving a request for a data transmission port giving a data transmission requirement, and performing subsequent processing for the data transmission request. At this time, the data transmission port in the software application end for externally receiving the data transmission instruction can be initialized to complete the preparation of cross-process data transmission, and the initialized data transmission port can be monitored by the local proxy server end, so that the local proxy server end can timely acquire the data transmission instruction input by the data transmission port.
In the above example, assuming that in the usage scenario of the automobile data recorder, the software application end is video playing software that needs to acquire video data, the data transmission port of the software application end may be considered as an SDK port related to MediaPlayer, after the construction of inter-process communication between the software application end and the local server end is completed, and after the configuration of the local proxy server end, callback interception of the player onPrepared may be set by invoking the setonpreparedlist method of the MediaPlayer, so as to further realize interception of the data transmission instruction input in the data transmission port by the local proxy server end.
S208, when the software application receives a data transmission instruction input by the data transmission port, if the instruction type of the data transmission instruction is a request type, executing S209; if the instruction type of the data transfer instruction is a stop type, S215 is performed.
Specifically, when the software application end receives the input data transmission instruction through the data transmission port, the software application end may be considered to have a requirement of performing data call or stopping data call, at this time, the instruction type of the data transmission instruction may be analyzed, if the instruction type is a request type, the software application end may be considered to be required to complete the cross-process data call to the data providing end through the local server end, at this time, step S209 is executed; if the instruction type is the stop type, the software application may consider that the execution of the cross-process data call from the local server to the data provider needs to be stopped, and step S215 is performed.
S209, setting a local network address for the data transmission port.
Specifically, after determining that software corresponding to the data transmission port needs to call and transmit data, in order to meet the local communication requirement, a software application end sets a predetermined local network address for the data transmission port.
With the above example, the software application may call the setDataSource method of the MediaPlayer corresponding to the data transmission port by using the generated local network address as a parameter, and then call the preplay method of the MediaPlayer, to trigger the initialized MediaPlayer to issue the data transmission request, so that the data transmission request may be monitored by the local proxy server corresponding to the local network address via the data transmission port.
And S210, when the local proxy server monitors a local data transmission request, updating the local data transmission request through presetting a real network domain name, presetting a real port number and presetting a data acquisition identifier, determining the updated local data transmission request as data transmission request information, and sending the data transmission request information to the interprocess communication client.
In this embodiment, the local data transmission request is specifically understood as a request issued by software with a data transmission requirement via a data transmission port for requesting a data call after initialization and local network address configuration are completed.
Specifically, when the local proxy server monitors the local data transmission request, it can be considered that the service accessing the software application through the data transmission port has a data transmission requirement, and when the local proxy server needs to send the local data transmission request to the local server and further send the data request to the data providing terminal with the real address through the local server, the information related to the real network address needs to be carried in the information sent to the local server, so that the local proxy server can update the local data transmission request through the preset real network domain name and the preset real port number corresponding to the preset real network address, and meanwhile, in order to make the local server definitely whether to perform data acquisition according to the data transmission request information input into the local proxy server, a preset data acquisition identifier for representing that data acquisition is required to be added in the updated local data transmission request, the local data transmission request with all the updates and the information added is determined as the data transmission request information, and the local proxy server sends the data transmission request information to the client of the software application.
In this way, when the local proxy server socket obtains the local data transmission request transmitted by the MediaPlayer through the data transmission port, the local network domain name and the port number in the local data transmission request are replaced by the network domain name and the port number in the real preset real network address, so as to generate the information of the data transmission request for the real network, and meanwhile, a preset data acquisition identifier, such as 'real_socket_request', is added in the previous year of the request information, the added request information is determined as the data transmission request information, and the data transmission request information is sent to the inter-process communication client LocalSocket.
S211, the inter-process communication client sends the data transmission request information to the inter-process communication server.
S212, the local server analyzes the data transmission request information, and if the data transmission request information contains a preset data acquisition identifier, the data transmission end is established at the local server according to a preset real network domain name and a preset real port number in the data transmission request information.
Specifically, the local server analyzes the data transmission request information when receiving the data transmission request information, if the data transmission request information after analysis contains the preset data acquisition identifier, the data transmission request information can be considered as request information for hopefully accessing the data providing end and acquiring feedback data, at this time, a data transmission end for accessing the data providing end can be created in the local server, and the data transmission end is configured through the preset real network domain name and the preset real port number in the data transmission request information, so that the data transmission end can directly perform data transmission with the data providing end with the real address after configuration.
In this way, after receiving the data transmission request information through the inter-process communication server LocalServerSocket, the local server Native Service analyzes the data transmission request information to determine whether the data transmission request information starts with the preset data acquisition identifier, if yes, a Socket is created in the local server Native Service as the data transmission end, and then the connection between the data transmission end and the data providing end is completed according to the preset real network domain name and the preset real port number in the data transmission request information, and then the data transmission request information received by the inter-process communication server LocalServerSocket is transferred to the data providing end.
S213, the data transmission end sends the data transmission request information to the data providing end.
