Detailed Description
In order to enable those skilled in the art to better understand the present application, a clear and complete description of the technical solution in the present embodiment will be provided below with reference to the accompanying drawings in the present embodiment. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The SOME/IP protocol is the most widely used SOA architecture communication protocol in the vehicle-mounted Ethernet, the core of the SOME/IP protocol is a service, and a Server and a Client (Client) usually exist in each service, and the Server provides the service and the Client calls the service. The services may include three types of interfaces, method (Method), event (Event), and process (Field).
A service may be understood approximately as a function, for example, a service may be to modify a window position, or to activate an exhaust fan to exhaust, etc., each service corresponds to having a control object, for example, when a service is "modify window position", the control object of the service may be "front left window, front right window, rear left window, and rear right window".
The Method interface is typically initiated by Client and replied to by Server, and is commonly used to modify data in the service. After the Method interface is called, whether the Server replies or not is determined according to the calling mode, and the Method interface can generally contain an indefinite number of input parameters and output parameters.
The Event interface usually only comprises 1 output parameter, and after the Event interface is subscribed by the Client, when a certain preset condition is met, the Server actively transmits data corresponding to the Event interface to the Client. The preset condition may be to transmit according to a certain period, or to transmit when data changes, or to set according to actual service design requirements.
The Field interfaces include three types of interfaces, namely: an acquisition interface (Getter), a setup interface (Setter), and a notification interface (Notifier).
The Client can request to acquire corresponding data from the Server through the Getter interface. The Client can modify data of the Server corresponding to the Client interface through the Client interface. The Notifier interface only comprises one output parameter, and after the Client subscribes to the Notifier interface on the Server, the Notifier interface immediately acquires data corresponding to the Notifier interface in one service and sends the data to the Client, and then acquires data corresponding to the Notifier interface every time a certain preset condition is met, and sends the acquired data to the Client. For example, assuming that the service is "adjust window position", when the Client subscribes to the Notifier interface corresponding to the left front window, the Notifier interface immediately sends the current position of the front left window; after that, assuming that the preset condition is "send once per second", the Notifier interface will acquire the position of the front left window once per second, and send the acquired position of the front left window to the Client.
Because one Field interface operates on the same control object in service, the parameter formats of the get interface, the set interface and the Notifier interface in the same file interface are all identical.
It should be noted that, as shown in fig. 1, a service may include an indefinite number of Method interfaces, event interfaces, and Field interfaces, and the number of Method interfaces, event interfaces, and Field interfaces is related to the complexity of the functions implemented when designing the service, which is not limited herein.
In practical business applications, there are three main operating requirements for data: modifying, actively inquiring and monitoring changes. The data is modified by a Method interface, actively inquired by a Getter interface, and passively acquired by an Event interface or a Notifier interface.
Since most business functions need to input multiple parameters, and the Method interface includes multiple input parameters and multiple output parameters, when the functions are actually implemented, the Method interface is called to modify data in the service. However, the format of each input parameter of the Method interface may be different, and when the Method interface is called, all the input parameters need to be input according to a certain rule (for example, input sequentially according to the input parameter sequence of the Method interface), and the input format must be all correct, which is troublesome. Therefore, how to reduce parameter input as much as possible and simplify the call flow while ensuring the accuracy and completeness of parameters when the Method interface is called is a problem to be solved.
Based on the above analysis, the inventor has provided the interface calling method, the device, the vehicle and the storage medium provided by the embodiment of the application through multiple experiments, through responding to the calling instruction of the method interface, multiple copies of the method interface are exposed to the sender of the calling instruction, the request parameter input by the sender for the target copy is obtained, the preset parameter of the target copy is combined with the request parameter to form a combined parameter, the method interface is called according to the combined parameter, the function corresponding to the calling instruction is executed, and because the multiple copies are split based on the method interface, and the same input parameter of the multiple copies is set as different preset parameters, the sender of the calling instruction can select one of the copies as the target copy according to the function requirement, and only the other input parameters than the preset parameters need to be input, but the preset parameters need not to be input, so that the number of the input parameters of the method interface can be reduced, the calling flow is simplified, and the calling efficiency of the interface is improved.
Referring to fig. 2, fig. 2 is a flow chart illustrating an interface calling method according to an embodiment of the application. The interface calling method can be applied to an interface calling device or a vehicle. The interface calling method may specifically include the following steps S110 to S130.
Step S110: and responding to the call instruction of the method interface, and exposing a plurality of copy copies of the method interface to an issuer of the call instruction, wherein the copy copies are split based on the method interface, and the same input parameters of the copy copies are set as different preset parameters.
The Server provides services such as "modify window position" services. A service is composed of a set of service interfaces, which may include the above-described Method type, event type, and Field type interfaces, and the number of interfaces of each type in a set of service interfaces may be determined according to the complexity of the service corresponding to the set of service interfaces. The Client can use the service corresponding to the service interface to realize a certain function by calling the service interface, for example, when the service is a 'modify window position' service, the Client can call a Method interface in the window position service to modify the position of a certain window. In this embodiment, the method interface corresponds to a service, and the sender of the call instruction may be a Client that uses the service, where the Client may be some device of a vehicle, such as a processor or controller. The Client may also be a functional system, such as an intelligent ventilation system, which may automatically control the opening of the vehicle window upon detecting that the smoke concentration value in the vehicle reaches a set concentration value. The functional system may be understood as an actual application system of a certain service or an actual application system formed by combining a plurality of services, for example, the intelligent ventilation system may be an actual application system formed by combining a smoke detection service, a window service and an air conditioning service.
In an embodiment of the present application, exposing the plurality of replication copies to the sender refers to making the plurality of replication copies in a state that can be known to the sender, and the sender can perform certain operations (e.g., inputting request parameters) on the plurality of replication copies.
The multiple copies are obtained by splitting the method interface before the call instruction is issued by the issuer. For example, the method interface may be replicated to obtain multiple replicated copies, and for each replicated copy, a certain input parameter of the replicated copy is set as a preset parameter, where the preset parameters of different replicated copies are different. The input parameters set as preset parameters in the duplicate copy are determined according to preset splitting rules for splitting the method interface in practice.
In some embodiments, in a scenario where service restoration is not required, the preset splitting rule may be based on an input parameter in the method interface for distinguishing the control object, and splitting the method interface. For example, referring to fig. 3 and fig. 4, if the input parameter for distinguishing the control object is "the control object", the method interface shown in fig. 3 may be split into four copies shown in fig. 4, where the input parameters for distinguishing the control object in the four copies are set to different preset parameters respectively, where the control object corresponding to the preset parameter 1 is a front left window, the control object corresponding to the preset parameter 2 is a front right window, the control object corresponding to the preset parameter 3 is a rear left window, and the control object corresponding to the preset parameter 4 is a rear right window.
In other embodiments, in a scenario where service restoration is not required, the preset splitting rule may be based on an input parameter used to set an operation type in the method interface, and split the method interface.
In still other embodiments, in a scenario where service restoration is required, the preset splitting rule may further be splitting the method interface based on splitting logic of a plurality of preselected interfaces (for example, a plurality of Event interfaces, or a plurality of get interfaces, or a plurality of Notifier interfaces) that are matched with the method interface and belong to the same specified type. For example, referring to fig. 5, splitting the method interface based on splitting logic of a plurality of pre-selected interfaces (e.g., a plurality of Event interfaces, or a plurality of get interfaces, or a plurality of Notifier interfaces) mated with the method interface may include the following steps S111 and S112.
Step S111: and acquiring a plurality of preselected interfaces which are matched with the method interfaces and belong to the same appointed type, wherein the operation data and the data formats of the matched method interfaces and the preselected interfaces are the same and are in the same service, and the appointed type comprises one of an Event interface type (namely an Event interface type), a notification interface type (namely a Notifier interface type) and an acquisition interface type (namely a get interface type).
For example, referring to fig. 3, in the service of "modifying window position", the method interface of fig. 3 has four input parameters, including: an input parameter for determining a control object, an input parameter for determining a type of operation, an input parameter for determining a position of a control object, and an input parameter for determining a control priority. Referring to fig. 6, the method interface shown in fig. 3 is matched with four get interfaces, four Event interfaces and four Notifier interfaces, and the plurality of pre-selected interfaces may be four get interfaces, four Event interfaces or four Notifier interfaces.
Step S112: based on the splitting logic of the plurality of preselected interfaces, the method interfaces are split to obtain a plurality of copy copies.
Wherein the method interface has a plurality of input parameters. The first characteristic values of the preselected interfaces can be determined according to the splitting logic of the preselected interfaces to obtain a plurality of first characteristic values, and different preselected interfaces correspond to different first characteristic values; determining a target input parameter from a plurality of input parameters of a method interface, wherein a plurality of first characteristic values correspond to the same target input parameter; copying the method interfaces to obtain a plurality of copy copies, wherein the number of the copy copies is the same as that of the preselected interfaces; and setting target input parameters in the plurality of copies to different preset parameters based on the plurality of first characteristic values, wherein each preset parameter corresponds to one first characteristic value, and each preset parameter corresponds to one copy.
The plurality of preselect interfaces of the same type are provided with certain splitting logic, and the plurality of preselect interfaces can be distinguished according to the splitting logic. When the method interface is duplicated, the input parameters included in each duplicated copy are consistent with the input parameters included in the method interface, and as shown in fig. 4, in each duplicated copy split by the method interface shown in fig. 3, the input parameters include a control object, an operation type, a target position and a control priority, and the meaning of the input parameters included in the method interface shown in fig. 3 and the data format are consistent; after setting the target input parameters in the multiple copies as different preset parameters, each copy has one input parameter which is already set as a preset parameter, as shown in fig. 4, the input parameters for distinguishing the control objects in the four copies are respectively set as different preset parameters 1, 2, 3 and 4, wherein the control object corresponding to the copy with the preset parameter of 1 is a front left window, the control object corresponding to the copy with the preset parameter of 2 is a front right window, the control object corresponding to the copy with the preset parameter of 3 is a rear left window, and the control object corresponding to the copy with the preset parameter of 4 is a rear right window.
It should be noted that, when the service is designed, the splitting logic of the multiple pre-selected interfaces of the same type in the service is determined by the specific function to be implemented by the service, and the relationships among the multiple first feature values of the multiple pre-selected interfaces of the same type correspond to the splitting logic.
For ease of understanding, referring to fig. 3, 4 and 6, the method interfaces shown in fig. 3 and the services corresponding to the plurality of pre-selected interfaces shown in fig. 6 are all "modified window positions", and based on the actual application scenario of the service, when designing the service, the splitting logic, i.e. "control object", of the plurality of pre-selected interfaces has been determined in advance. Based on the splitting logic, determining first characteristic values of the plurality of preselected interfaces as: front left window, front right window, back left window, and back right window. In the method interface, the input parameters corresponding to the first characteristic values are found to be control objects, the method interface is used for copying four copy copies shown in fig. 4, the control objects of the four copy copies are respectively set to be 1, 2, 3 and 4 to correspond to the four different first characteristic values, wherein 1 corresponds to a front left window, 2 corresponds to a front right window, 3 corresponds to a rear left window, and 4 corresponds to a rear right window, so that the final four copy copies are obtained.
In some implementations, all input parameters for multiple duplicate copies may be exposed to the issuer; in this case, the sender can only input other parameters than the preset parameters, and the preset parameters cannot be input.
In some embodiments, considering that the number of the copy copies of the method interface is larger and the storage space is occupied, in order to save the storage space, a part of the copy copies except for a preset parameter can be exposed to an issuer based on the identification information of the copy copies, and by hiding the preset parameter in the copy copies, only the part of the copy copies except for the preset parameter is displayed, so that the storage space can be saved to a certain extent, and meanwhile, the content of the copy copies exposed to the issuer can be reduced, thereby reducing the 'seen' information of the issuer.
The multiple copies have different identification information that may be set prior to exposing the multiple copies to the issuer. The identification information of each copy corresponds to a preset parameter in the copy or corresponds to a first characteristic value corresponding to the copy. The identification information is used to uniquely identify the duplicate copies to distinguish between the different duplicate copies so that the sender can identify the different duplicate copies based on the identification information to input the request parameters for the duplicate copies corresponding to the control object to be controlled. The identification information may be the name of the duplicate copy, or may be an identification number (IdentityDocument, ID), or may be other information that can be used to uniquely identify the duplicate copy, which is not limited herein. The setting form of the identification information is preferably that the sender of the call instruction can accurately identify the call instruction.
Step S120: and acquiring request parameters input by an issuer aiming at the target copy, combining preset parameters of the target copy with the request parameters to form combined parameters, wherein the target copy is one of a plurality of copy copies.
After exposing the plurality of copy copies to the sender, the sender can identify control objects corresponding to different copy copies through the identification information, and the sender selects one copy of the plurality of copy copies as a target copy according to the control object which is actually wanted to be controlled, and inputs request parameters to the target copy. The request parameters refer to other input parameters input by the sender besides preset parameters. As shown in fig. 4, the request parameters may be an operation type, a target position, and a control priority other than the control object.
And responding to an ending instruction of the request parameters input by the sender aiming at the target copy, and acquiring the request parameters input by the sender aiming at the target copy. The ending instruction may be a preset character, and when detecting that the sender inputs the preset character, the ending instruction determines that the sender inputs the preset character, and takes a character before the preset character as a request parameter.
Step S130: and calling the method interface according to the combined parameters, and executing the function corresponding to the calling instruction.
It should be noted that, because the duplicate copy itself does not have the function of the method interface, and the method interface needs to be invoked with complete input parameters, after the request parameters are obtained, the request parameters and the preset parameters of the target copy need to be combined to form combined parameters, and the original method interface is invoked by using the combined parameters, so as to implement the corresponding function. For example, assume that the target copy is the copy in fig. 7, and the preset parameter in the target copy is "1" for characterizing the control object as the front left window. When the target copy is called, the "control object" is hidden, and the issuer can only input other parts than the "control object". Assuming that the operation type is "1", the target position is "20%", and the control priority is "1" in the request parameters of the target copy, the combination parameters in the target copy are: the method comprises the steps of sequentially inputting 1, 20 percent and 1 in combination parameters into a method interface as input parameters of the method interface, namely calling an original method interface, and realizing the function of modifying the window position of a left front window.
According to the interface calling method provided by the embodiment of the application, the multiple copies of the method interface are exposed to the sender of the calling instruction through responding to the calling instruction of the method interface, the request parameter input by the sender aiming at the target copy is obtained, the preset parameter of the target copy is combined with the request parameter to form the combined parameter, the method interface is called according to the combined parameter, the function corresponding to the calling instruction is executed, and as the multiple copies are obtained by splitting the method interface, the same input parameter of the multiple copies is set to be different preset parameters, the sender of the calling instruction can select one of the copies as the target copy according to the function requirement, and only the other input parameters except the preset parameter are input without inputting the preset parameter, so that the number of the input parameters of the method interface can be reduced, the calling process is simplified, and the calling efficiency of the interface is improved.
In the related art, when the service involves automatic rollback or restoration, that is, in a scenario where service restoration is required, before the method interface is called to modify data, the initial state of the control object needs to be acquired through the pre-selected interface, after modification is finished, the initial state is then used as an input parameter to be transferred into the method interface, and the method interface is called again to complete rollback.
However, in the method interface, "the input parameter for determining the control object" generally has a plurality of values, that is, when the same method interface is called, the control object is different according to the input "the input parameter for determining the control object". Each pre-selection interface (for example, event interface or Notifier interface or get interface) only corresponds to one control object, only has one output parameter, the output parameter of the pre-selection interface is input into the method interface, and the method interface cannot identify the corresponding control object, so that the service rollback or restoration is difficult to realize.
For example, the pre-selection interface (e.g., event interface or Notifier interface or get interface) shown in fig. 6 has only the target position (e.g., 50%) of the output parameter, and the method interface only obtains the target position (e.g., 50%), which is the control object that cannot determine the target position, so that the pre-selection interface cannot be directly associated with the method interface, that is, the service cannot be rolled back or restored.
In order to realize the rollback or restoration of the service, as shown in fig. 8, in the related art, a method interface and a pre-selected interface are manually judged, and the corresponding relationship is written into a code to perform fixed definition, so that output parameters acquired by the pre-selected interface can be used as input parameters to enter the method interface, and a control object can be correctly identified by the method interface. However, for higher complexity services, this approach consumes excessive resources, is costly and inefficient to implement.
In some embodiments, to enable more efficient rollback or restoration of the service, referring to fig. 9, before step S130, the interface calling method further includes step S140, and after step S130, the interface calling method further includes step S150 to implement a rollback operation of the service.
Step S140: and acquiring an initial state value of the control object corresponding to the target preselection interface through the target preselection interface associated with the target copy.
In some embodiments, considering that some services need to be restored after use or after a period of use, multiple copies and multiple pre-selected interfaces may be associated, where each copy corresponds to one pre-selected interface, so that output parameters of the pre-selected interfaces serve as input parameters of the copy, and meanwhile, control objects of the copy are preset, that is, operations of rollback or restoration can be correctly performed on the services, so that efficiency is improved.
The method comprises the steps that a plurality of copy copies and a plurality of pre-selected interfaces can be matched according to first characteristic values of the plurality of pre-selected interfaces and preset parameters of the plurality of copy copies, and the preset parameters of the copy copies and the first characteristic values of the pre-selected interfaces have corresponding relations in the matched copy copies and the pre-selected interfaces; determining a second characteristic value according to output parameters of a plurality of preselected interfaces, wherein the preselected interfaces correspond to the same second characteristic value; for each of the plurality of duplicate copies, determining an input parameter corresponding to the second characteristic value in the input parameters of the current duplicate copy as an associated parameter of the current duplicate copy; and associating the preselected interface matched with the current copy based on the association parameters.
For ease of understanding, referring to fig. 10, for the four copies obtained in the example, since the preset parameters of the four copies are set according to the first characteristic values of the four preselected interfaces, respectively, the four copies may be matched with the four preselected interfaces one by one. Since the type of the pre-selected interface is one of a get, event, or Notifier, the pre-selected interface has only one output parameter. And acquiring a second characteristic value, namely a 'position', according to the output parameters of the four preselected interfaces. As shown in fig. 10, in the duplicate copy, the input parameter corresponding to the "position" is found as the "target position" as the associated parameter of the duplicate copy.
In this embodiment, since the control object of each copy is unique, the preselected interface that cannot be directly associated with the method interface may be directly associated with the copy, that is, the rollback or restoration of the service may be efficiently performed.
In some embodiments, in the process of calling the method interface, the real-time state value of the control object corresponding to the target pre-selection interface can be obtained through the target pre-selection interface associated with the target copy, so as to monitor the state change condition of the control object corresponding to the target pre-selection interface. The type of the target pre-selection interface may be one of a Getter, an Event, or a Notifier, which is not limited herein. For example, when the method interface is called to adjust the position of the vehicle window, the adjusted position of the vehicle window can be acquired for multiple times in a certain time period through an Event and fed back to the user in a visual mode, so that the user can monitor the state of the vehicle window.
The target pre-selection interface may be a Getter interface or a Notifier interface corresponding to the target copy.
It should be noted that, in the service, the control object in the service receives a state of being objectively present, for example, in the service of "adjusting the window positions", each window has an objectively present position. The "initial state value" is the current state value of the control object corresponding to the target pre-selection interface before the method interface is called by the calling instruction, for example, the control object of the target copy is the left front window, the current window position of the left front window is 50%, and the obtained initial state value is 50%.
Step S150: based on the initial state value of the control object and the target copy, the state of the control object is restored to the initial state.
In some embodiments, the initial state values may be assigned to associated parameters in the target copy, and other input parameters in the target copy are along with the request parameters, and recombined to form the rollback parameters.
For example, as shown in fig. 11, assuming that the control object is a front left window, the current position (i.e. the initial state value) of the front left window may be obtained and stored through a corresponding target pre-selection interface (e.g. a Getter interface) of the front left window position, after the function is implemented by calling the instruction calling method interface, the stored current position of the front left window is assigned to the associated parameters of the target copy for use, and parameter combination is performed again to form a rollback parameter, and the function of recovering the window position is implemented by calling the method interface using the rollback parameter.
Based on step S140 and step S150, after the method interface is called for data modification, the target copy is used, that is, the unique control object is determined, so that the rollback parameter can be formed by combining the temporarily stored initial state value, the preset parameter in the target copy and the other used request parameter, and the method interface is called again, thereby more efficiently completing the rollback operation on the service.
