Step 103, the parameter-configuring request that application program is sent is received.
In the embodiment of the present application, parameter-configuring request is component configuration parameter for requesting.
Illustratively, when component is video encoder, parameter may include following at least one: resolution ratio, bit rate, position
Rate type, code stream type, picture quality and frame per second etc..Resolution ratio indicates the size of image, for the figure of video recording to be arranged
As size.Bit rate is also known as code rate, refers to data volume caused by single recording channel in the unit time.Bit rate type is also known as code
Rate type, there is dynamic code rate and two kinds of solid-state code rate, and dynamic code rate refers to the process of that encoder is carrying out compressed encoding to image
In, according to the situation of image adjust in real time code rate height, cbr (constant bit rate) refer to encoder during being encoded to image,
A cbr (constant bit rate) value is used from beginning to end.Code stream type includes: combined-flow (only including the code stream of video and audio data), view
Frequency stream (the only code stream of video data), audio stream (the only code stream of audio data).Image quality parameter can compile video
The value range of code device is finely adjusted.Frame per second indicates image frames numbers of the video within the unit time.
Step 104, according to the Permission Levels of application program, determine whether application program has the permission of calling interface.
In the embodiment of the present application, interface is used to the interface of component configuration parameter.Terminal is receiving application program
After the parameter-configuring request of transmission, determine to need the component for carrying out parameter configuration and the parameter accordingly needed to configure.So
Afterwards, terminal is determined according to the component and parameter for the interface for the component configuration parameter.
One interface can be used for configuring a kind of parameter, can be used for configuration many kinds of parameters, the embodiment of the present application is to this
It is not construed as limiting.
Illustratively, the Permission Levels of application program can be determined according to permission list.
The Permission Levels of at least one application program are stored in permission list.For example, comprising applying journey in permission list
Corresponding relationship between the mark and Permission Levels of sequence.The mark of application program is different for uniquely indicating the application program
Application program has different marks.For example, the mark of application program can be packet name (referred to as " the application packet of application program
Name ") or other unique identifiers.Terminal obtains Permission Levels corresponding with the mark of application program from permission list,
Permission Levels as the application program.
In the embodiment of the present application, different Permission Levels have the permission for calling distinct interface.For example, different permissions
Grade has the permission for the interface for calling variety classes and quantity.Optionally, the Permission Levels of application program are higher, this applies journey
The interface that sequence is capable of calling is more.
Optionally, in permission list, the corresponding Permission Levels of application packet name.Illustratively, Permission Levels pair
The numerical value answered is bigger, and Permission Levels are lower.Assuming that there are four grades for Permission Levels, if being 4 using the corresponding Permission Levels of packet name 1
Grade is then minimum using the corresponding Permission Levels of packet name 1；If being 1 grade using the corresponding Permission Levels of packet name 2,2 pairs of packet name are applied
The Permission Levels highest answered.
The corresponding relationship of application Bao Mingyu Permission Levels can be stored in permission list by terminal.As shown in Fig. 2, it shows
Example property shows the overall schematic of technical scheme.Terminal storage has permission list 21, includes 4 in the permission list 21
A Permission Levels, i.e., 1 grade, 2 grades, 3 grades and 4 grades, the Permission Levels highest of 1 grade of representative, the Permission Levels of 2 grades, 3 grades, 4 grades representatives
It successively reduces, the Permission Levels of 4 grades of representatives are minimum.Assuming that application program 1, application program 2, application program 3 and application program 4 are right
Answer application packet name be respectively apply packet name 1, using packet name 2, using packet name 3 and apply packet name 4, using the corresponding power of packet name 1
Limiting grade is 2 grades, is 3 grades using the corresponding Permission Levels of packet name 2, is 1 grade, using packet using the corresponding Permission Levels of packet name 3
4 corresponding Permission Levels of name are 4 grades.Terminal according to permission list, can determine that the Permission Levels of application program 1 are 2 grades, application
The Permission Levels of program 2 are 3 grades, and the Permission Levels of application program 3 are 1 grade, and the Permission Levels of application program 4 are 4 grades.Certainly,
The same Permission Levels can be corresponding with multiple application packet names namely multiple and different application programs Permission Levels having the same.
In one example, when needing to obtain the Permission Levels of a certain application program, if do not included in permission list
When Permission Levels corresponding with the mark of the application program, default privilege grade is determined as the permission of the application program by terminal
Grade.Optionally, default privilege grade is least privilege grade.For example, the Permission Levels of application program 5 are if desired obtained, power
There is no the mark of application program 5 in limit list, then the Permission Levels of application program 5 are determined as 4 grades by terminal.
In another example, when needing to obtain the Permission Levels of a certain application program, if do not wrapped in permission list
When containing Permission Levels corresponding with the mark of the application program, terminal can determine the power of the application program in the following manner
Limit grade:
1, the characteristic information of the application program is obtained；
Characteristic information can be the information of any feature that can embody application program, for example, the developer of application program,
The type of application program, the CPU occupancy of application program, EMS memory occupation amount, interface calling sequence etc..The embodiment of the present application pair
The particular content of characteristic information is not construed as limiting.
2, according to the characteristic information of the application program, from permission list, the similarity highest with the application program is chosen
Application program；
Illustratively, terminal can calculate between the two application programs according to the characteristic information of two application programs
Similarity.For example, by preparatory trained neural network model, the characteristic information of two application programs is defeated as model
Enter, the similarity of the two application programs is exported by the model.When needing to obtain the Permission Levels of a certain application program, terminal
It is ranked up the similarity between the application program and other application program is descending, against sequencing of similarity from permission
The highest application program of similarity with the application program is chosen in list.
3, by Permission Levels corresponding with the highest application program of the similarity of the application program, as the application program
Permission Levels.
The corresponding Permission Levels of the highest application program of similarity are determined according to permission list, and as the application
The Permission Levels of program.By by Permission Levels corresponding with the highest application program of the similarity of the application program, as
The Permission Levels of the application program, determining Permission Levels are more reasonable, accurate.
In addition, permission list can be created by terminal, it can also be created by server, terminal can be by network from service
Device synchronizes to obtain.In addition, permission list can also regularly update, updated permission list is handed down to terminal by server.
In addition, the interface that each Permission Levels is capable of calling, can preset and store in the terminal.The permission etc.
Corresponding relationship between grade and the interface being capable of calling, also can recorde in permission list.Illustratively, it is wrapped in permission list
Containing the first corresponding relationship and the second corresponding relationship.Wherein, the first corresponding relationship refer to the mark of application program described above with
Corresponding relationship between Permission Levels.Second corresponding relationship refers to the corresponding relationship between interface level and interface identifier.Interface
Mark is for playing the role of unique identification to interface.Each interface level can correspond to one or more interfaces.Different
Permission Levels have the permission for the interface for calling distinct interface rank.Certainly, in some other examples, above-mentioned first is corresponding
Relationship and the second corresponding relationship can be stored respectively, such as the first corresponding relationship is stored in permission list, and second is corresponding
Relationship is stored in interface level list.
As shown in Fig. 2, terminal is also stored with interface level list 22.It is not at the same level comprising 4 kinds in the interface level list 22
Other interface, i.e. 1 grade of interface, 2 grades of interfaces, 3 grades of interfaces and 4 grades of interfaces, each interface level can correspond to one or more
A interface.If the corresponding Permission Levels of application program are 1 grade (Permission Levels highest), which can call 1 grade to connect
Mouth, 2 grades of interfaces, 3 grades of interfaces and 4 grades of interfaces；If the corresponding Permission Levels of application program are 4 grades (Permission Levels are minimum), should
Application program can only call 4 grades of interfaces；If the corresponding Permission Levels of application program are 3 grades, which can call 3
Grade interface and 4 grades of interfaces；If the corresponding Permission Levels of application program are 2 grades, which can call 2 grades of interfaces, 3 grades
Interface and 4 grades of interfaces.
Step 105, if application program has the permission for calling the interface, calling the interface is component configuration parameter.
Still taking the above example as an example, it is assumed that application requests are component configuration parameter A, and parameter A, which needs to call, to be connect
Mouth A is configured, and interface A belongs to 1 grade of interface, and the corresponding Permission Levels of application program are 1 grade, then the application program has calling
The permission of 1 grade of interface, then it is component configuration parameter A that terminal, which calls interface A,.
Optionally, if application program does not have the permission of calling interface, parameter-configuring request is refused to respond, or call
Interface is component Configuration default parameters.
Assuming that application requests are component configuration parameter B, parameter B needs calling interface B to be configured, and interface B belongs to
In 2 grades of interfaces, the corresponding Permission Levels of application program are 3 grades, then the application program does not have the permission for calling 2 grades of interfaces, then
Terminal refuses to respond the parameter-configuring request of the application program.
In alternatively possible embodiment, in the case where application program does not have the permission of calling interface B, terminal
It can not also be the parameter configured to component Configuration terminal request using calling interface B as component configuration parameter, but be the group
Part allocating default parameter.Wherein, default parameters, which refers to, belongs to one species, but the parameter that value is different with parameter.Default parameters
It can be the parameter of a preset minimalist configuration.For example, the code rate that application requests are video encoder configuration is
60, but the Permission Levels of application program do not have this are called to be used to configure the interface of code rate, then although terminal calls the interface
Code rate is configured for video encoder, but the code rate configured is 30.
In conclusion passing through the permission etc. different for application setting in technical solution provided by the embodiments of the present application
Grade, different Permission Levels have the permission for calling distinct interface, need to call a certain interface for its creation in application program
When component Configuration relevant parameter, operating system judges whether the application program has the permission for calling the interface, if having
Calling the interface is that application program completes above-mentioned parameter configuration, and interface management mode provided by the embodiments of the present application is more flexible
Property, facilitate the runnability for promoting terminal and application program.
Illustratively, server can determine the corresponding Permission Levels of application program according to the performance information of application program.

In the embodiment of the present application, performance information is used to indicate the movement of application program in the process of running.Performance information
It may include following at least one: the order information of calling interface, the legality message of parameter, the application of resource and release information
Etc..The order information of calling interface is used to indicate sequence when application call distinct interface.For example, application program A tune
Sequence when with distinct interface is first calling interface 1, then calling interface 2, last calling interface 3.The legality message of parameter
It is used to indicate the legitimacy of the parameter in the parameter-configuring request of application program.For example, the legitimacy of parameter values type.Resource
Application and release information be used to indicate the release conditions after application program resource, resource can refer to terminal memory or
CPU usage or other resources etc..
Following steps can also be performed in terminal:
1, the performance information of acquisition applications program；
Terminal can be every the performance information of preset time acquisition applications program.
2, the performance information of application program is sent to server；
3, the permission adjustment information for the application program that server is sent is received；

Whole information.The permission adjustment information of application program is used to indicate the Permission Levels of terminal adjustment application program.
Still taking the above example as an example, server can determine the permission of application program according to the order information of calling interface
Adjustment information.For example, the basic calling sequence of application program is first calling interface 1, interface 2, last calling interface 3 are recalled；
If the calling sequence of the order information instruction application program of calling interface calls sequence consensus, the performance of application program with basic
Well, server can properly increase the Permission Levels of application program, if the original Permission Levels of application program are 4 grades, then take
Business device is adjusted to 3 grades.
Server can also determine the permission adjustment information of application program according to the legality message of parameter.For example, parameter A
Corresponding value type is number, and the corresponding value type of parameter A carried in parameter-configuring request is letter, then parameter A
Illegal, the performance of application program is poor, and server can suitably reduce the Permission Levels of application program, if application program is original
Permission Levels be 4 grades (Permission Levels are minimum), then server still determine the application program Permission Levels be 4 grades；If answering
It is 3 grades with the original Permission Levels of program, then server can be adjusted to 4 grades.
Server can also determine the permission adjustment information of application program according to the application and release information of resource.For example,
Application program did not discharged the resource after originally having called resource, and can discharge the money after the complete resource of application call now
The performance in source, application program is good, and server can properly increase the Permission Levels of application program, original power such as application program
Limiting grade is 4 grades, then server is adjusted to 3 grades.
Server can also comprehensively consider the order information of calling interface, the legality message of parameter, resource application and
Any two or three in information is discharged, the Permission Levels of application program are adjusted.
4, according to the permission adjustment information of application program, the Permission Levels of application program are adjusted.
If the instruction of permission adjustment information improves the Permission Levels of application program, terminal correspondingly improves the power of application program
Limit grade；If the instruction of permission adjustment information reduces the Permission Levels of application program, terminal accordingly decreases the power of application program
Limit grade.
Optionally, in permission adjustment information include application program Permission Levels adjusted instruction information, terminal according to
The instruction information is adjusted the Permission Levels of application program.
In conclusion in technical solution provided by the embodiments of the present application, by the performance information of acquisition applications program, and will
Performance information is sent to server, so that server determines the permission adjustment information of application program according to above-mentioned performance information,
Terminal makes corresponding adjustment to the Permission Levels of application program according to the permission adjustment information, improves the flexible of permission control
