It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

The method may be performed by a data invocation device, which may be implemented in software and/or hardware, typically integrated in a terminal.
As shown in fig. 1, a data calling method includes:
s101, obtaining interface data of an SO module, wherein the interface data comprises a name of a class corresponding to an application layer, an interface function name corresponding to the application layer and signature information corresponding to the application layer;
in a possible implementation manner, the step of establishing an initial data call template according to the name of the class of the application layer, the name of the interface function corresponding to the application layer, and the signature information corresponding to the application layer includes:
storing the name of the class corresponding to the application layer, the name of the interface function corresponding to the application layer and the signature information corresponding to the application layer to obtain a data structure;
and taking the data structure body as the initial data calling template.
Illustratively, one data structure is defined to contain all data:
Struct methodinfo{
string classname;
string methodname;
string methodsig;}
wherein, string classname; the name of the corresponding class of the application layer is stored in a character string mode; string methodname; storing the interface name of the application layer corresponding to the SO module interface; string methodsig; storing function signature information of an interface of an application layer corresponding to the SO module interface, namely the return value type of the function and all parameter types; struct method is a functional statement that defines the structure.
Illustratively, the data structure is used to store the name of the class of the corresponding application layer, the name of the interface of the corresponding application layer and the function signature information of the interface of the corresponding application layer, SO that the subsequent quick search of the SO module interface can be facilitated.
In a possible embodiment, the step of storing the name of the class corresponding to the application layer, the name of the interface function corresponding to the application layer, and the signature information corresponding to the application layer to obtain the data structure includes:
and storing the name of the class of the application layer, the name of the interface function corresponding to the application layer and the signature information corresponding to the application layer according to a set storage mode to obtain the data structure body.
Illustratively, a set function statement is employed:
set<methodinfo>methodset;
the set storage is realized, one method of one class can be guaranteed to be unique, so that a developer can check conveniently, when a repeated method is defined, the set function statement can check that the repeated method exists, and further informs the developer of an error.
S102, establishing an initial data calling template corresponding to the interface function name of the application layer and the signature information corresponding to the application layer according to the class name of the application layer;
in a possible implementation manner, the step of generating a target data call template according to the data to be called and the initial data call template includes:
storing the initial data calling template into a preset interface of the SO module;
and carrying out unicity detection on the initial data calling template.
Illustratively, the preset interface of the SO module is written:
bool AddMethod(char*classname,char*methodname,char*methodsig){
wherein, AddMethod is the name of the interface, classname is the name of the class corresponding to the application layer, methodname is the name of the method corresponding to the application layer, and methodsig is the signature information of the interface corresponding to the application layer.
Illustratively, a preset interface of the SO module is written to store a method for data call between an interface other than the preset interface of the SO module and the application layer, and a method for detecting whether the same method exists in the method for data call between the interface other than the preset interface and the application layer is performed in a single way, SO that whether a human development error exists can be known in a development stage.
In a possible implementation, the step of performing a uniqueness test on the initial data call template includes:
constructing a methodinfo structure
Methodinfo m(classname,methodname,methodsig);
The parameters of the above structure are: classname corresponds to the name of the class of the application layer, methodname corresponds to the name of the method of the application layer, and methodsig corresponds to the signature information of the interface of the application layer.
Bool bFond=methodset.find(m);
See if there is a duplicate interface by the set lookup find interface.
If the returned value bfound is true, it indicates that the same interface is found, and indicates that the above-mentioned interface has been stored before, and reports an error, and prompts the developer that the current interface has been created before, so that it is possible to find that the program has an error during the program development without reporting an error when the program is executed.
If the returned value bfound is false, indicating that no finding was found, then it is possible to insert a statement:
Methodset.insert(m);
the insertion of the interface is performed.
Illustratively, errors are found in time in the development process of the program, so that the problem that the errors can be found only when the program is executed is avoided, further, the complete program inspection by developers is avoided, the workload of the developers is reduced, and the research and development efficiency is improved.
In a possible implementation, the step of performing a uniqueness test on the initial data call template includes:
defining a first macrocommand:
#define CHECK_METHOD(classname,methodname,methodsig)\
static bool bstatic_##methodid=AddMethod(classname,methodname,methodsig);\
and detecting the initial data call template, wherein the macro command adopts a static variable bstatic _ # method, the AddMethod is a preset interface name of a module providing data for an application layer, the Classname is a name of a class corresponding to the application layer, the methodname is a name of an interface function corresponding to the application layer, and the methodsig is signature information corresponding to the application layer.
Illustratively, the written interface is checked immediately when the interface is written, so that a developer can timely know whether the currently written interface is registered or not when developing, the definition and the check of the written interface parameters are bound together to form a whole, and the parameter modification cannot be missed if the interface is modified subsequently.
S103, acquiring a function parameter to be called according to the request for calling the interface data;
in one possible implementation, the interface hasId in the SO module is written to be provided to the application layer for use:
CHECK_METHOD(javaClassName,"hasId","(I)Z")
JNIEXPORT jboolean JNICALL Java_com_hashId(JNIEnv*_env,jclass,jint_taskid){
JNIEPORT represents that the interface is exported to an application layer for use, jboilean represents a return value, JNICALL represents a function to be called in the SO module, Java _ com _ hashId represents a function name to be called in the SO module, and JNIENV _ env, jclass and jnt _ taskid are parameters of the function to be called in the SO module.
Illustratively, invoking the second macro command:
CHECK_METHOD(javaClassName,"hasId","(I)Z")
wherein CHECK _ METHOD is the first macro command; javaClassName is the class name of the application layer in the corresponding so module interface; "hasId" is the application layer function name corresponding to the so module interface in the application layer; and "(I) Z" represents the signature information of the so module interface, wherein the signature information is the parameter and the return value of the function to be called in the so module.
In a possible implementation manner, the step of obtaining the parameter of the function to be called according to the request for calling the interface data includes:
registering data to be called corresponding to the request to the initial data calling template according to the request for calling the interface data to acquire the function parameter to be called, wherein the function parameter comprises a function name of the data to be called, a parameter of the data to be called and signature information of the application layer.
Exemplarily, the interface detection of the SO module and the definition process of the function of the application layer are set before the process of accessing the interface, SO that forgetting to define the interface definition of the SO module corresponding to the application layer is avoided, and meanwhile, when the number of parameters or the types of the parameters need to be modified, the definition of the function of the application layer and the definition process of the interface of the SO module corresponding to the application layer are combined, SO that the modification is facilitated, and the modification is not easy to forget; and simultaneously, AddMethod is called in the concrete realization of the macro to check the function, so that the same function is prevented from being written, and the writing error can be timely found.
S104, generating a target data calling function according to the function parameter to be called and the initial data calling template;
in a possible implementation manner, before the calling the function based on the target data completes the call to the data in the SO module, the method further includes:
the functional signature of the interface is verified.
Illustratively, all interfaces with JNIEXPORT are scanned;
scanning out all interface calls of CHECK _ METHOD;
the verification is performed based on all interfaces with JNIEXPORT and all interfaces of CHECK _ METHOD.
Illustratively, if the SO module interface defines JNIEXPORT, it indicates that the interface is an interface provided for application layer invocation, and when the interface does not define interface invocation of CHECK _ METHOD, an alarm is given to prompt a developer that the current interface does not define interface invocation of CHECK _ METHOD, SO that an error prompt can be directly given in a development stage.
If the developer defines the interface call of the CHECK _ METHOD, detecting whether the interface name provided by the interface to the application layer has a one-to-one corresponding METHOD in the class and the interface of the application layer, wherein the interface comprises the class name, the METHOD name and the parameter signature corresponding to the application layer, and if the one-to-one corresponding METHOD is not found in the class and the interface of the application layer by the interface name provided by the interface to the application layer, alarming is also carried out to prompt the developer to have a current definition error.
Furthermore, the matching of the signature of the interface and the parameters is detected, and even if the interface is defined and the method of the application layer is also defined, the parameter type can only know whether the interface is matched or not when the program is executed, and the program execution needs to go through complicated processes of packaging, compiling, executing and the like. And scanning the interface declared as JNIEXXPORT on the so module to obtain the return value of the interface of the JNIEXXPORT, the number of the parameters and the parameter type of each parameter.
And (3) finding the signature information methodsig during interface registration from the CHECK _ METHOD, and analyzing a function return value, the number of parameters and the parameter type of each parameter based on the signature information.
Comparing the analyzed parameters with the signature information methodsig transmitted in the CHECK _ METHOD, so as to compare whether the parameters are consistent with all the parameters of the signature information, if not, directly prompting a developer that the current definition is wrong, and directly prompting parameter errors or return value errors in a development stage, thereby avoiding the problem of program crash caused by mismatching of the parameters when the developer executes a program.
In a possible implementation manner, before the step of completing the call to the data in the SO module based on the target data calling function, the method further includes:
when the so module is initialized, detecting whether parameters of all interfaces are consistent with signature information of an application layer;
if not, alarming and notifying the technician.
Illustratively, the corresponding java class instance is obtained: when the data to be called is registered, 3 parameters, namely class name, methodname and methodsig, are bound, wherein the parameters are respectively the name of the class, the name of the method and the signature information of the method.
By functional statement:
class cls=env->FindClass(classname);
whether the java class exists is searched through the FindClass of the jni interface, a search result is obtained through a returned value cls, if the java class does not exist, the application layer does not have the interface, an alarm is given, and error information is given;
the method for acquiring the corresponding java class comprises the following steps:
and after the corresponding java class is acquired, acquiring the corresponding java class, if the method and the parameter are matched, acquiring the method, and if the method and the parameter are not matched and the acquired method is empty, directly judging that the current parameter or the method is not matched, indicating that an error exists and giving an alarm.
By means of the function:
jmethodID mid=env->GetMethodID(cls,methodname,methodsig);
the cls is the searched java class, the methodname is a method of the SO module interface corresponding to the application layer, and the methodsig represents the signature information of the method of the corresponding java class.
If the return value mid is not null, the method of finding the corresponding java class is indicated;
if the return value mid is empty, it indicates that the corresponding java class method is not found, and error information can be prompted to give an alarm.
And S105, calling the data in the SO module based on the target data calling function.
In one possible embodiment, the method further comprises:
counting the number of the initial data calling templates in the preset interface in real time;
and carrying out log output on any initial data calling template according to the number of the initial data calling templates.
Illustratively, an interface AddMethod is defined to register all interfaces, and a variable methodset is used to store all interfaces for java layers in the SO module, SO that the number of the interfaces provided by the current SO module can be easily counted, and then log output can be conveniently performed on all the interfaces, that is, all elements in the methodset only need to be traversed, and all the interfaces can be conveniently output, SO that the number and the parameter types of the interfaces in the SO module can be conveniently compared, the function defined by the SO module can be conveniently known, and functions such as interface registration monitoring function, historical change information of the interfaces and the like can be conveniently added based on a uniform interface.
The method comprises the steps that interface data of an SO module are obtained, wherein the interface data comprise names of classes corresponding to an application layer, names of interface functions corresponding to the application layer and signature information corresponding to the application layer; establishing an initial data calling template corresponding to the interface function name of the application layer and the signature information corresponding to the application layer according to the name of the class of the application layer; acquiring a function parameter to be called according to the request for calling the interface data; generating a target data calling function according to the function parameter to be called and the initial data calling template; and calling a function based on the target data to finish calling the data in the SO module. The interface data comprises the name of the class corresponding to the application layer, the name of the interface function corresponding to the application layer, the signature information corresponding to the application layer and the function parameter of the data to be called are combined to generate the target data calling function, so that the signature information and the interface information are convenient to correspond, the risk that the signature information and the interface information are wrongly corresponded or wrongly written due to the fact that the signature information and the interface information of the application layer are separately written when the data are called is reduced, and further developers can conveniently maintain programs. The interface checking function is carried out immediately when the interface of each SO module is written, SO that a developer can conveniently know whether the interface is registered or not when developing, the definition and the checking of the interface parameters are integrated, and the modification of the parameters cannot be missed if any modification is carried out subsequently.
