Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

Referring to fig. 1, a schematic diagram of an implementation environment of the information acquisition method provided in the embodiment of the present application is shown. The implementation environment may be an information acquisition system 10, where the information acquisition system 10 includes: a first client 11 and a second client 12.

The first client 11 and the second client 12 may be installed in the same terminal, or may be installed in different terminals, which is not limited in this embodiment of the present application. The first client 11 and the second client 12 may implement an information obtaining process based on the method provided in the embodiment of the present application. In one possible implementation, the first client 11 may call an interface of the second client 12 to obtain information by means of RPC. In the course of communication based on the RPC method, the first client 11 that initiates the RPC request is used as a client, and the second client 12 that provides service for the RPC request is used as a server.

Illustratively, the first client 11 may be a merchant client installed in the self-service payment terminal, and the second client 12 may be a human face client installed in the self-service payment terminal. As shown in fig. 2, the self-service payment terminal 13 is an electronic device for realizing self-service shopping, and is generally disposed in a supermarket, a store and other places, and is capable of enabling a user to scan goods and check out payment in a self-service manner. When the user selects the face-brushing payment, the merchant client can call a related interface of the face client in an RPC (remote position control) mode to identify the face of the user and acquire identity information or payment code information corresponding to the user.

It should be understood by those skilled in the art that the first client 11 and the second client 12 are only examples, and other existing or future first clients and second clients may be applicable to the present application, and are included in the scope of the present application and are herein incorporated by reference.

Based on the implementation environment shown in fig. 1, an embodiment of the present application provides an information obtaining method, which is applied to an interaction process between a first client and a second client as an example. As shown in fig. 3, the method provided by the embodiment of the present application may include the following steps:

in step 301, a first client receives a first instruction for acquiring first information through a first interface, where the first interface is any interface among a plurality of interfaces of the first client, and at least two interfaces of the plurality of interfaces multiplex a communication link.

The first client is any client needing to acquire information from the second client, the first client is provided with a plurality of interfaces, and at least two interfaces in the plurality of interfaces of the first client multiplex a communication link. The multiplexing of one communication link by at least two interfaces means that the at least two interfaces communicate with the interface in the second client through the same communication link. It should be noted that, in the embodiment of the present application, the specific number of the interfaces multiplexing the same communication link is not limited, as long as at least two interfaces are ensured to multiplex the same communication link. In one possible implementation, the multiple interfaces of the first client each multiplex the same communication link. At this time, all the interfaces in the first client communicate with the interface of the second client through the same communication link.

Exemplarily, it is assumed that the first client has 5 interfaces, interface 1, interface 2, interface 3, interface 4, and interface 5, respectively. The multiplexing of at least two interfaces by one communication link may mean that interface 1 and interface 2 multiplex communication link 1, and interface 3, interface 4 and interface 5 multiplex communication link 2. Of course, that at least two interfaces multiplex one communication link may also mean that interface 1, interface 2, interface 3, interface 4, and interface 5 all multiplex communication link 1.

The first interface is any interface in a plurality of interfaces of the first client. In this embodiment of the application, the first information is information that the first client needs to obtain currently, and the first instruction is an instruction for obtaining the first information. The first interface is an interface capable of receiving a first command. The first client may receive a first instruction to obtain first information through the first interface. It should be noted that, according to a difference in function or type of the first interface, the first client may receive, through the first interface, a different first instruction for acquiring different first information.

Exemplarily, assuming that the first client is a merchant client in the self-service payment terminal and the second client is a face client in the self-service payment terminal, the first interface may be an interface capable of receiving an instruction for acquiring user identity information in the merchant client, or may be an interface capable of receiving an instruction for acquiring user payment code information in the merchant client. For the condition that the first interface is an interface which can receive an instruction for acquiring user identity information in the merchant client, the first information is the user identity information, the first instruction is the instruction for acquiring the user identity information, and the first client can receive the instruction for acquiring the user identity information through the first interface; for the condition that the first interface is an interface which can receive an instruction for acquiring user payment code information in the merchant client, the first information is the user payment code information, the first instruction is the instruction for acquiring the user payment code information, and the first client can receive the instruction for acquiring the user payment code information through the first interface.

In one possible implementation, the first instruction for acquiring the first information may be generated based on a trigger operation of a user. Different trigger operations may generate different first instructions for obtaining different first information. Illustratively, when a face-brushing payment triggering operation of the user is detected, a first instruction for acquiring payment code information of the user can be generated, and at the moment, the first information is the payment code information of the user; when the user identity authentication triggering operation is detected, a first instruction for acquiring the user identity information may be generated, and at this time, the first information is the user identity information. The first client may store a corresponding relationship between the instruction and the interface, and after generating the first instruction, the first client determines the first interface in the corresponding relationship between the instruction and the interface, and then receives the first instruction through the first interface.

In step 302, the first client converts the first instruction into a first command word, generating a first remote procedure call, RPC, request comprising the first command word.

The first client may convert the first instruction into a first command word after receiving the first instruction through the first interface. The first command word may refer to a representation of the first instruction that facilitates communication over the communication link multiplexed by the first interface. That is, the first command word and the first instruction correspond to each other, and both of them represent the same meaning with different expressions, and since the first instruction is used to indicate that the first information needs to be acquired, the first command word is also used to indicate that the first information needs to be acquired.

In one possible implementation, the manner in which the first client converts the first instruction into the first command word includes, but is not limited to, the following two:

the first method is as follows: the first client converts the first instruction into a first command word based on a first conversion mode.

In this manner, the bottom layer of the first client may store a first conversion scheme for converting instructions into command words. The first conversion method may be formulated by a developer of the first client, or may be freely adjusted according to an actual application scenario, which is not limited in the embodiment of the present application. The first client may automatically convert the first instruction into the first command word at the bottom layer based on the first conversion mode.

The second method comprises the following steps: the first client stores the corresponding relation between the instruction and the command word, queries a first command word corresponding to the first instruction based on the corresponding relation between the instruction and the command word, and then converts the first instruction into the first command word.

After obtaining the first command word, the first client generates a first RPC request including the first command word. The first RPC request is used for requesting to call an interface of the second client to acquire first information. RPC is a protocol that requests services from a remote computer program over a network without knowledge of the underlying network technology. Based on the RPC mode, the communication between the two clients can be realized.

For an Android operating system, RPC communication may be implemented based on AIDL (Android interface definition Language). In the process of realizing RPC communication based on AIDL, two roles are included: a client and a server. In the embodiment of the present application, the first client that generates the first RPC request is used as a client, that is, an SDK (Software Development Kit) of the client that integrates the aid id in the first client; and taking the second client which acquires the first information based on the PRC request as a service machine, namely integrating the SDK of the service machine of the AIDL with the second client.

In one possible implementation, after generating the first RPC request, the first client may encode the first RPC request to encode the first RPC request into a format capable of network transmission.

In step 303, the first client sends the first RPC request to the second client over the target communication link multiplexed by the first interface.

It should be noted that, since at least two interfaces of the plurality of interfaces of the first client multiplex one communication link, there is at least one interface that also multiplexes the target communication link in addition to the first interface. In one possible implementation, multiple interfaces in the first client each multiplex the target communication link. That is, there is only one target communication link for all interfaces in the first client to communicate with all interfaces in the second client.

In one possible implementation manner, the manner in which the first client sends the first RPC request to the second client through the target communication link is as follows: and the first client sends the first RPC request after the coding processing to the second client through the target communication link.

The second client is a client capable of providing the first information for the first client. For example, in the case that the first client is a merchant client in the self-service payment terminal and the first information is user payment code information, the second client may be a face client in the self-service payment terminal, and the face client may provide the user payment code information for the merchant client, so that the merchant performs a subsequent deduction process based on the user payment code information.

In step 304, the second client receives the first remote procedure call, RPC, request sent by the first client over the target communication link.

After the first client sends the first RPC request to the second client through the target communication link, the second client can receive the first RPC request through the target communication link. The first RPC request comprises a first command word, wherein the first command word is obtained by converting a first instruction used for acquiring first information. Since the first command word corresponds to the first instruction association, the first command word in the first RPC request is used to indicate that the first information needs to be obtained.

In one possible implementation manner, for a case that the first client sends the encoded first RPC request to the second client through the target communication link, the second client receives the encoded first RPC request through the target communication link. After receiving the first RPC request subjected to encoding processing, the second client needs to decode the first RPC request subjected to encoding processing to obtain the first RPC request.

In a possible implementation manner, after receiving the first RPC request, the second client may parse the first RPC request to obtain the first command word, so as to determine the service logic to be executed according to the first command word. In the embodiment of the present application, since the first command word indicates that the first information needs to be acquired, the service logic that needs to be executed may be determined to acquire the first information according to the first command word.

In one possible implementation manner, the second client parses the first RPC request, and the manner of obtaining the first command word may be: and the second client identifies the format of each message in the first RPC request, and extracts the message in the command word format to obtain the first command word. It should be noted that the manner of parsing the first RPC request and obtaining the first command word is only an exemplary description, and the embodiment of the present application does not limit this.

The second client has a plurality of interfaces, different interfaces for executing different business logic. After the first command word is obtained, the second client needs to determine a target interface for executing the service logic corresponding to the first command word, so as to execute the service logic corresponding to the first command word by calling the target interface. In one possible implementation, the second client is configured with a mapping of command words and interfaces. In one possible implementation, in the mapping relationship between the command word and the interface, the same interface in different versions may have a mapping relationship with the same command word, thereby improving compatibility between interfaces in different versions.

After obtaining the first command word, the second client may determine whether a target interface having a mapping relationship with the first command word exists based on a mapping relationship between the command word and the interface. The process may be: the second client inquires the first command word in the mapping relation between the command word and the interface; responding to the fact that the mapping relation between the command word and the interfaces comprises the first command word, and a target interface corresponding to the first RPC request exists in the plurality of interfaces of the second client; and responding to the condition that the mapping relation between the command word and the interface does not comprise the first command word, and not having a target interface corresponding to the first RPC request in the plurality of interfaces of the second client.

When the mapping relationship between the command word and the interface includes the first command word, a target interface having a mapping relationship with the first command word may be directly determined according to the mapping relationship between the command word and the interface, which indicates that a target interface corresponding to the first RPC request exists in the plurality of interfaces of the second client, and step 305 is executed; when the mapping relationship between the command word and the interface does not include the first command word, a target interface having a mapping relationship with the first command word cannot be determined according to the mapping relationship between the command word and the interface, which indicates that no target interface corresponding to the first RPC request exists in the plurality of interfaces of the second client.

In one possible implementation, in response to no target interface corresponding to the first RPC request among the plurality of interfaces of the second client, the second client sends the hint information to the first client through the target communication link. The prompt information is used for prompting the first client, and a target interface corresponding to the first RPC request does not exist in the plurality of interfaces of the second client. In one possible implementation, the prompt may be an error message, and the prompt may include a possible reason for the error. By the method, the phenomenon of abnormal interruption of the information acquisition process caused by the absence of the called interface can be avoided, and the stability of the information acquisition process is high.

After the second client sends the prompt message to the first client through the target communication link, the first client receives the prompt message sent by the second client through the target communication link, and the prompt message is used for indicating that the second client does not have a target interface corresponding to the first RPC request. After receiving the prompt message, the first client may present the prompt message to inform the user that the first message was not successfully obtained. Exemplarily, in a scene that a user performs face brushing payment by using a self-service payment terminal, the prompt information may inform that the user fails to successfully acquire payment code information corresponding to the face of the user, so that the user performs face brushing or changes other payment modes again, and user experience is improved.

In step 305, the second client calls a target interface corresponding to the first RPC request to obtain the first information, and at least two interfaces of the plurality of interfaces of the second client multiplex a communication link.

The target interface is an interface for acquiring the first information. When a target interface corresponding to the first RPC request exists in the plurality of interfaces of the second client, the second client calls the target interface corresponding to the first RPC request to acquire first information.

Illustratively, for the case that the second client is a face client in the self-service payment terminal, in a scene that the user performs payment by using a face-brushing payment method, the first information is user payment code information. The process that the second client calls the target interface to acquire the first information is as follows: and the second client calls the target interface to identify the face of the user, determines a user account corresponding to the face of the user, and takes the payment code information corresponding to the user account as the first information.

It should be noted that, the interfaces of the first client and the second client communicate with each other through the communication link. Therefore, for the second client, at least two of the plurality of interfaces of the second client also multiplex a communication link to ensure efficient communication with the interface of the first client. It should be noted that any interface in the first client and the interface to be called in the second client corresponding to the interface correspond to the same communication link.

In a possible implementation manner, when a plurality of interfaces of the first client all multiplex the target communication link, a plurality of interfaces to be called in the second client corresponding to the respective interfaces of the first client also all multiplex the target communication link.

For example, the process of the second client calling the target interface to obtain the first information may be as shown in fig. 4. In fig. 4, the merchant client 41 is a first client, and the face client 42 is a second client. The merchant client 41 is a client in the RPC communication process, and the face client 42 is a server in the RPC communication process. The interface 1 and the interface 2 of the merchant client multiplex a target communication link, and the interface 1 and the interface 2 of the face client multiplex the target communication link. The interface 1 of the merchant client can receive an instruction for acquiring user identity information, and the interface 2 of the merchant client can receive an instruction for acquiring user payment code information. Interface 1 and interface 2 of the merchant client can both be used as the first interface.

Assuming that the information currently required to be acquired is user identity information, the interface 1 of the merchant client is used as a first interface. After receiving an instruction for acquiring user identity information through the interface 1, the merchant client converts the instruction into a first command word, where the first command word may be represented as cmd: gettuserinfo. Assuming that the information which needs to be acquired currently is user payment code information, the interface 2 of the merchant client is used as a first interface. After receiving an instruction for acquiring user payment code information through the interface 2, the merchant client converts the instruction into a first command word, wherein the first command word can be represented as cmd: getfacecode.

After the merchant client obtains the first command word, a first RPC request including the first command word is generated. After the first RPC request is generated, the merchant client sends the first RPC request to the face client through the target communication link. After receiving the first RPC request, the face client analyzes the first RPC request to obtain a first command word. And then determining a target interface according to the mapping relation between the command word and the interface. It is assumed that the mapping of the command word and the interface indicates that the command word cmd: gettuserinfo has a mapping with interface 1 and the command word cmd: getfacecode has a mapping with interface 2. When the first command word is cmd: gettuserinfo, the interface 1 is a target interface, and the face client calls the interface 1 to acquire the user identity information, so that the face client acquires the first information; when the first command word is cmd: getfacecode, the interface 2 is a target interface, and the face client calls the interface 2 to acquire the face payment code information of the user, so that the face client acquires the first information. In the embodiment of the application, a high-availability compatibility processing mechanism is provided by a mode that at least two interfaces multiplex a bottom layer of communication link, and user experience is improved.

In step 306, the second client converts the first information into a second command word, and sends the second command word to the first client through the target communication link.

And after calling the target interface to acquire the first information, the second client converts the first information into a second command word so as to be transmitted in the target communication link. The second command word corresponds to the first information, and both of them have the same meaning by different expressions.

In one possible implementation, the manner in which the second client converts the first information into the second command word includes, but is not limited to, the following two:

the first method is as follows: and the second client converts the first information into a second command word based on a second conversion mode.

In this manner, the underlying layer of the second client may store a second conversion scheme for converting information into command words. The second conversion mode may be formulated by a developer of the second client, or may be freely adjusted according to an actual application scenario, which is not limited in the embodiment of the present application. The second client may automatically convert the first information into the second command word at the bottom layer based on the second conversion manner.

The second conversion method may be the same as or different from the first conversion method, and this is not limited in the embodiments of the present application.

The second method comprises the following steps: the first client inquires a second command word corresponding to the first information based on the corresponding relation between the information and the command word, and then converts the first information into the second command word.

After converting the first information into the second command word, the second client sends the second command word to the first client through the target communication link.

In step 307, the first client receives the second command word sent by the second client through the target communication link, and converts the second command word into the first information.

After the second client sends the second command word to the first client through the target communication link, the first client receives the second command word through the target communication link and then converts the second command word into first information which can be directly utilized.

In one possible implementation, the manner in which the first client converts the second command word into the first information includes, but is not limited to, the following two:

the first method is as follows: and the first client converts the second command word into the first information based on the third conversion mode.

In this way, the bottom layer of the first client may store a third conversion means for converting the command word into information. The third conversion mode may be formulated by a developer of the first client according to a reverse process of converting information into command words, or may be freely adjusted according to an actual application scenario, which is not limited in the embodiment of the present application. The first client may automatically convert the second command word into the first information at the bottom layer based on the third conversion manner.

The second method comprises the following steps: the first client stores the corresponding relation between the information and the command word, queries the first information corresponding to the second command word based on the corresponding relation between the information and the command word, and then converts the second command word into the first information.

In a possible implementation manner, after the first client receives, through the target communication link, the second command word sent by the second client, the method further includes: and determining a second interface having a mapping relation with the second command word in the plurality of interfaces of the first client based on the mapping relation of the command word and the interfaces. The second interface having a mapping relationship with the second command word refers to an interface capable of utilizing the first information represented by the second command word. The second interface may be the same as or different from the first interface, and this is not limited in this application.

After determining the second interface and converting the second command word into the first information, the first client may feed back the first information to the second interface for the second interface to perform a subsequent process using the first information.

For example, assuming that the first information is user payment code information, the second interface may transfer funds from the user's account to the merchant's account using the user payment code information; assuming that the first information is user identity information, the second interface may verify the identity of the user using the user identity information.

In a possible implementation manner, in a scenario of performing a face-brushing payment by using a self-service payment terminal, the implementation code of the process of acquiring the first information may be as follows:
