Detailed Description
So that the manner in which the features and aspects of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.
Example one
The embodiment of the invention provides a method for searching backup data; the method is applied to the terminal; specifically, fig. 1 is a schematic diagram of an implementation flow of a method for searching backup data according to an embodiment of the present invention; FIG. 2 is a schematic diagram of an application framework according to an embodiment of the present invention; in practical applications, as shown in fig. 2, the terminal may access the network through the signal transmission tower and further access the application server, for example, the terminal accesses the network through WIreless Fidelity (Wi-Fi) and then accesses the application server; or, the terminal can also access the network through the base station, and then access the application server, so as to run the target application program on the terminal; here, the application server stores a target application and various functional components corresponding to the target application, i.e., plug-ins and the like. Based on the application framework shown in fig. 2, the method of this embodiment includes:
step 101: determining a target plug-in; the target plug-in is a plug-in with changed data characteristics in a target application program;
in this embodiment, the change of the data characteristic may specifically indicate a change such as data update or data loss. For example, after the target application program is updated, the plug-in corresponding to the target application program is also updated correspondingly, or part of data is lost without updating correspondingly, so that the plug-in cannot operate normally, and at this time, the plug-in which cannot operate normally due to updating or data loss is taken as the target plug-in.
Step 102: acquiring plug-in identification information and compatible feature information corresponding to the target plug-in;
in practical application, the plug-in identification information corresponding to the target plug-in may specifically be a file name of the target plug-in; the compatible feature information may be a compatible Identification (ID), i.e. a file compatibility characteristic, written in the program of the target plug-in. Here, the terminal may determine whether the backup data is compatible with the target plug-in through the compatibility identifier; for example, when the compatible identifier of the target plug-in represented by the compatible feature information is the same as the compatible identifier in the backup data, it indicates that the backup data is compatible with the target plug-in; otherwise, it indicates that the backup data is incompatible with the target plug-in.
Step 103: obtaining a target characteristic value of the target plug-in based on plug-in identification information and compatible characteristic information corresponding to the target plug-in;
step 104: and searching whether target backup data matched with the target characteristic value exists in the stored backup data corresponding to the target plug-in.
In practical applications, the target feature value may specifically be a Message Digest Algorithm fifth version (MD 5, Message Digest Algorithm 5) value; that is to say, the terminal determines the MD5 value corresponding to the target plug-in according to the plug-in identification information and the compatible feature information corresponding to the target plug-in. Here, since the MD5 value is determined based on the plug-in identification information and compatible feature information corresponding to the target plug-in, that is, the MD5 value corresponding to the target plug-in can represent both the identification information and the compatible feature of the target plug-in; therefore, when the terminal finds out the target backup data matched with the MD5 value corresponding to the target plug-in from the stored backup data corresponding to the target plug-in, the target backup data is the backup data available and compatible to the target plug-in.
In an embodiment, in order to facilitate the terminal to determine the backup data corresponding to the target plug-in, the terminal further needs to obtain location information of the backup data corresponding to the target plug-in, for example, determine a directory where the backup data corresponding to the target plug-in is located, and then search, by using the location information, whether there is target backup data matching the target characteristic value from the stored backup data corresponding to the target plug-in.
In a specific application, when a search result represents that target backup data matched with the target characteristic value exists, verifying the target backup data, and further determining whether to operate the target plug-in by using the target backup data based on a verification result; specifically, when the data characteristics of the target backup data represented by the verification result do not change, the target backup data is multiplexed to operate the target plug-in by using the target backup data; and when the verification result represents that the data characteristics of the target backup data are changed, generating prompt information to prompt a user to download the target backup data again.
Or when the search result represents that the target backup data matched with the target characteristic value does not exist, generating prompt information to prompt a user to download the target backup data again. Here, the verification may specifically be signature verification; for example, a check is made according to the format of the signature to determine whether the target backup data is modified by the format of the signature.
Specifically, as shown in fig. 3, after the target application program of the terminal is upgraded, the target plug-in is also upgraded correspondingly, at this time, if the user uses the function corresponding to the target plug-in advance, the terminal needs to acquire the backup data corresponding to the target plug-in so as to operate the target plug-in, where the specific acquisition process is as follows:
the terminal acquires the file name and the compatible identification of the target plug-in, the MD5 value of the target plug-in is determined according to the file name and the compatible identification of the target plug-in and a preset calculation rule, then the MD5 value of the target plug-in is utilized to search whether target backup data with the same MD5 value as the target plug-in exists in backup data corresponding to the target plug-in stored in the terminal, and at the moment, a display interface of the terminal presents prompt information of 'searching for the target backup data' so as to inform a user of waiting for a search result; further, as shown in fig. 3-1, after the terminal finds the target backup data having the same MD5 value as the target plug-in, the terminal prompts the user to confirm whether to immediately run the target backup data, such as decompressing the target backup data, and then run the target plug-in; or, as shown in fig. 3-2, when the terminal does not find the target backup data with the same MD5 value as the target plug-in, the terminal prompts the user to "find no target backup data", and simultaneously prompts the user to "whether to download the target backup data".
Therefore, compared with the mode that the existing plug-in mechanism only simply judges whether the backup data is available through file name verification, and further determines whether the backup data is compatible after the backup data is determined to be available, the method provided by the embodiment of the invention can find out the target backup data which is available for the target plug-in and compatible with the target plug-in through one-time searching process, so that the searching process is reduced, the searching process is enabled to be fast, the searching efficiency is improved, and the user experience is further improved.
Moreover, according to the method provided by the embodiment of the invention, when the target plug-in is updated or the data is lost, the backup data corresponding to the target plug-in before updating does not need to be directly deleted, whether the available target backup data exists in the backup data corresponding to the target plug-in before updating is firstly searched, the next operation is determined according to the searching result, for example, when the target backup data exists, the target backup data is multiplexed, the target plug-in is further operated, and when the target backup data is not searched, the user is informed to download the target backup data.
Example two
Based on the method described in the first embodiment, in order to ensure that the terminal can find the target backup data matched with the target characteristic value in the backup data corresponding to the target plug-in stored in the terminal based on the target characteristic value of the target plug-in, such as the MD5 value; in this embodiment, before step 104, the method for searching backup data further includes:
step A: obtaining backup data of at least one plug-in corresponding to the target application program;
and B: acquiring plug-in identification information and compatible feature information of at least one plug-in corresponding to the target application program;
and C: generating a characteristic value of at least one plug-in according to plug-in identification information and compatible characteristic information of the at least one plug-in corresponding to the target application program;
the characteristic value described in this embodiment is also specifically an MD5 value, for example, the terminal determines, according to a preset calculation rule, an MD5 value corresponding to each plug-in according to the plug-in identification information and the compatible characteristic information of each plug-in, that is, according to the file name and the compatible identification of each plug-in, renames the backup data corresponding to each plug-in according to the MD5 value, and further causes the terminal to store the backup data according to the renamed file name. Therefore, a foundation is laid for the terminal to quickly search the target backup data corresponding to the target plug-in, and meanwhile, a foundation is laid for reusing the backup data.
Step D: obtaining backup identification information of backup data corresponding to the at least one plug-in based on the characteristic value of the at least one plug-in;
step E: and storing the backup data corresponding to the at least one plug-in by using the backup identification information.
In this embodiment, when the terminal stores the backup data of the plug-in corresponding to the target application, the terminal may set backup identification information for each backup data according to the plug-in identification information and the compatible feature information, and set a file name of the backup data according to the plug-in identification information and the compatible feature information, so that whether the backup data is the target backup data corresponding to the target plug-in may be determined according to the stored file name of each backup data, and meanwhile, whether the backup data is the target backup data compatible with the target plug-in may also be determined.
Here, in practical applications, the backup data obtained in step a usually exists in the form of compressed packets, for example, Zip packets; as shown in fig. 4, it is assumed that a file name of backup data corresponding to a plug-in acquired by a terminal is a first file name, where the first file name only represents a corresponding relationship between the backup data and the plug-in and cannot represent a compatible feature of the backup data, the terminal acquires plug-in identification information corresponding to the plug-in, such as a file name of the plug-in, and compatible feature information, such as a compatible identifier of the plug-in, and then the terminal renames the backup data corresponding to the plug-in by using the file name and the compatible identifier of the plug-in, such as naming the second file name, where the second file name can represent both the corresponding relationship between the plug-in and the compatible feature, and thus, a foundation is laid for the terminal to quickly search for target backup data corresponding to a target plug-in.
Here, when the terminal names backup data corresponding to all plug-ins of its own target application program based on the naming rule, the named backup data is stored in a corresponding directory, and then, when the target application program of the terminal is upgraded, the target plug-ins are also upgraded correspondingly, or part of data is lost without corresponding update, so that the target plug-ins cannot run normally, the terminal may determine a target characteristic value by obtaining plug-in identification information and compatible characteristic information corresponding to the target plug-ins, and then search for whether to store the target backup data matched with the target plug-ins according to the target characteristic value; specifically, fig. 5 is a schematic flowchart of a specific implementation of a method for searching backup data according to an embodiment of the present invention; as shown in figure 5 of the drawings,
step 501: the plug-in module after the target APP version is upgraded or the target APP is decompressed has data loss, and at the moment, the plug-in module with the data loss serves as the target plug-in module;
step 502: the terminal searches a target directory where the backup file corresponding to the target plug-in is located from a database corresponding to the terminal;
step 503: the terminal obtains the file name and the compatible identification of the target plug-in, and obtains a target MD5 value according to the file name and the compatible identification of the target plug-in;
here, the execution order of steps 502 and 503 may be reversed.
Step 504: searching whether target backup data matched with the target MD5 value exists in the target directory; if yes, go to step 505; otherwise, go to step 507;
here, the terminal stores the backup data in the form of Zip compressed packets.
Step 505: the terminal performs signature verification on the Zip packet of the target backup data to determine whether the target backup data is tampered; when it is determined to be tampered, performing step 507; otherwise, go to step 506;
step 506: and the terminal decompresses the Zip packet of the target backup data and multiplexes the target backup data to operate the target plug-in.
Step 507: and the terminal generates prompt information to prompt the user to download the target backup data again or prompt the user of an error.
EXAMPLE III
Based on the method described in the first embodiment or the second embodiment, the present embodiment provides a specific application scenario; specifically, the method comprises the following steps:
the application scene one:
the terminal may also detect whether it is able to access the target communication network, e.g., whether it is able to access Wi-Fi; when the target communication network is not accessed, the terminal searches whether target backup data matched with the target characteristic value exists in the stored backup data corresponding to the target plug-in.
Therefore, a foundation is laid for the terminal to be capable of quickly operating the target plug-in, a foundation is laid for multiplexing backup data, and a foundation is laid for improving user experience.
Further, when the terminal fails to access a target communication network, such as Wi-Fi, and when the search result indicates that no target backup data matching the target feature value exists, the terminal may generate a prompt message as shown in fig. 6, prompt the user that the user is not currently in Wi-Fi but in a mobile network, and further select to immediately download or cancel downloading the target backup data according to the user requirement. Therefore, target backup data can be prevented from being downloaded directly, a foundation is laid for the user to save the flow, and the user experience is improved.
Further, when the terminal can access the target communication network, for example, can access Wi-Fi, and when the search result indicates that there is no target backup data matching the target characteristic value, for example, no target backup data having the backup identification information identical to the MD5 value of the target plug-in is found from the backup data corresponding to the target plug-in, the terminal may download the target backup data using the target communication network, so that a user is prevented from downloading the target backup data using mobile data, traffic is saved for the user, and user experience is improved.
Application scenario two:
the terminal firstly executes processing according to the sequence from step 101 to step 104; when step 104 is executed, the method specifically includes:
searching whether target backup data matched with the target characteristic value exist in stored backup data corresponding to the target plug-in;
when the search result represents that the target backup data matched with the target characteristic value exists, the terminal does not need to detect whether the terminal can be accessed to a target communication network;
when the search result indicates that the target backup data matched with the target characteristic value does not exist, the terminal detects whether the target communication network can be accessed, and then when the terminal can be accessed to the target communication network, such as Wi-Fi can be accessed, the target communication network is used for downloading the target backup data; when the target communication network cannot be accessed, such as Wi-Fi, the prompt message shown in fig. 6 is generated, or the prompt message shown in fig. 3-2 is generated, that is, "target backup data is not found, and whether the target backup data is downloaded or not".
Therefore, the method of the embodiment of the invention can combine the process of determining whether the data are compatible with the process of searching the target backup data into a whole, quickly locate the available and compatible target backup data, reduce the Input/Output (I/O) operation at the terminal and shorten the operation time; moreover, the backup data stored by the terminal is fully utilized, the reuse rate of the backup data is improved, the waiting time of a user is further reduced, and the user experience is improved.
Example four
An embodiment of the present invention provides a terminal, as shown in fig. 2, where the terminal according to the embodiment of the present invention may access a network through a signal transmission tower, and then access an application server, for example, the terminal accesses the network through a WIreless Fidelity (Wi-Fi) and then accesses the application server; or, the base station is accessed into the network, and then is accessed into the application program server, so as to run the target application program at the terminal; here, the application server stores a target application and various functional components corresponding to the target application, i.e., plug-ins and the like. Based on the application framework shown in fig. 2, as shown in fig. 7, the terminal includes:
a determination unit 71 for determining a target plug-in; the target plug-in is a plug-in with changed data characteristics in a target application program;
an information obtaining unit 72, configured to obtain plug-in identification information and compatible feature information corresponding to the target plug-in;
a feature value generating unit 73, configured to obtain a target feature value of the target plug-in based on the plug-in identification information and the compatible feature information corresponding to the target plug-in;
and the data processing unit 74 is configured to search, from the stored backup data corresponding to the target plug-in, whether there is target backup data matching the target characteristic value.
In this embodiment, the change of the data characteristic may specifically indicate a change such as data update or data loss. For example, after the target application program is updated, the plug-in corresponding to the target application program is also updated correspondingly, or part of data is lost without updating correspondingly, so that the plug-in cannot operate normally, and at this time, the determining unit takes the plug-in which cannot operate normally due to updating or data loss as the target plug-in.
In practical application, the plug-in identification information corresponding to the target plug-in may specifically be a file name of the target plug-in; the compatible feature information may be a compatible Identification (ID), i.e. a file compatibility characteristic, written in the program of the target plug-in. Here, the terminal may determine whether the backup data is compatible with the target plug-in through the compatibility identifier; for example, when the compatible identifier of the target plug-in represented by the compatible feature information is the same as the compatible identifier in the backup data, it indicates that the backup data is compatible with the target plug-in; otherwise, it indicates that the backup data is incompatible with the target plug-in.
In practical applications, the target feature value may specifically be a Message Digest Algorithm fifth version (MD 5, Message Digest Algorithm 5) value; that is, the feature value generation unit determines the MD5 value corresponding to the target plug-in according to the plug-in identification information and the compatible feature information corresponding to the target plug-in. Here, since the MD5 value is determined based on the plug-in identification information and compatible feature information corresponding to the target plug-in, that is, the MD5 value corresponding to the target plug-in can represent both the identification information and the compatible feature of the target plug-in; therefore, when the data processing unit finds out the target backup data matched with the MD5 value corresponding to the target plug-in from the stored backup data corresponding to the target plug-in, the target backup data is the backup data that is available and compatible for the target plug-in.
In an embodiment, in order to facilitate the terminal to determine the backup data corresponding to the target plug-in, the terminal further needs to obtain location information of the backup data corresponding to the target plug-in, for example, determine a directory where the backup data corresponding to the target plug-in is located, and then search, by using the location information, whether there is target backup data matching the target characteristic value from the stored backup data corresponding to the target plug-in.
In this embodiment, in order to ensure that the terminal can find, based on a target characteristic value of the target plug-in, such as an MD5 value, target backup data that matches the target characteristic value from among backup data that is stored in the terminal and corresponds to the target plug-in; as shown in fig. 8, the terminal further includes: a storage unit 75; wherein,
the information obtaining unit 72 is further configured to obtain backup data, plug-in identification information, and compatible feature information of at least one plug-in corresponding to the target application;
the feature value generating unit 73 is further configured to generate a feature value of at least one plug-in according to the plug-in identification information and the compatible feature information of the at least one plug-in corresponding to the target application program, and obtain backup identification information of backup data corresponding to the at least one plug-in based on the feature value of the at least one plug-in;
the storage unit 75 is configured to store backup data corresponding to the at least one plug-in by using the backup identification information.
Here, the characteristic value is also specifically an MD5 value, for example, the characteristic value generating unit determines an MD5 value corresponding to each plug-in according to the plug-in identification information and the compatible characteristic information of each plug-in, that is, according to the file name and the compatible identification of each plug-in, and renames the backup data corresponding to each plug-in according to the MD5 value, so that the storage unit stores the backup data according to the renamed file name. Therefore, a foundation is laid for the terminal to quickly search the target backup data corresponding to the target plug-in, and meanwhile, a foundation is laid for reusing the backup data.
In this embodiment, when the terminal stores the backup data of the plug-in corresponding to the target application, the terminal may set backup identification information for each backup data according to the plug-in identification information and the compatible feature information, and set a file name of the backup data according to the plug-in identification information and the compatible feature information, so that whether the backup data is the target backup data corresponding to the target plug-in may be determined according to the stored file name of each backup data, and meanwhile, whether the backup data is the target backup data compatible with the target plug-in may also be determined.
In practical applications, the backup data acquired by the information acquisition unit usually exists in the form of compressed packets, for example, Zip packets; as shown in fig. 4, it is assumed that the file name of the backup data corresponding to the plug-in acquired by the information acquisition unit is a first file name, where the first file name only represents the corresponding relationship between the backup data and the plug-in and cannot represent the compatible feature of the backup data, the information acquisition unit acquires plug-in identification information corresponding to the plug-in, such as the file name of the plug-in, and compatible feature information, such as the compatible identifier of the plug-in, and then the feature value generation unit renames the backup data corresponding to the plug-in by using the file name and the compatible identifier of the plug-in, such as naming the second file name, at this time, the second file name represents both the corresponding relationship between the plug-in and the compatible feature, so as to lay a foundation for the terminal to quickly search for the target backup data corresponding to the target plug-in.
Here, after the feature value generating unit names backup data corresponding to all plug-ins of its own target application program based on the naming rule, the named backup data is stored in a corresponding directory by the storage unit, and then, after the target application program of the terminal is upgraded, the target plug-ins are also upgraded correspondingly, or part of data is lost without corresponding update, so that the target plug-ins cannot run normally, the terminal may determine a target feature value by using the plug-in identification information and the compatible feature information corresponding to the target plug-ins, and then search for whether to store the target backup data matched with the target plug-ins according to the target feature value; specifically, the implementation process may be shown in fig. 5, and is not described here again.
In a specific application, the data processing unit is further configured to perform verification processing on the target backup data when the search result represents that the target backup data matched with the target characteristic value exists; and determining whether to operate the target plug-in by using the target backup data based on the verification result. Specifically, the method is further configured to run the target plug-in by using the target backup data when the verification result indicates that the data characteristics of the target backup data do not change; or when the verification result represents that the data characteristics of the target backup data change, generating prompt information to prompt a user to download the target backup data again. Here, the verification may specifically be signature verification; for example, a check is made according to the format of the signature to determine whether the target backup data is modified by the format of the signature.
As shown in fig. 3, after the target application program of the terminal is upgraded, the target plug-in is also upgraded correspondingly, at this time, if the user uses the function corresponding to the target plug-in advance, the terminal needs to acquire the backup data corresponding to the target plug-in so as to operate the target plug-in, and the specific acquisition process is as follows:
the information acquisition unit acquires a file name and a compatible identifier of the target plugin, the characteristic value generation unit determines an MD5 value of the target plugin according to the file name and the compatible identifier of the target plugin and a preset calculation rule, the data processing unit searches whether target backup data with the same MD5 value as the target plugin exists in backup data corresponding to the target plugin stored in the terminal by using the MD5 value of the target plugin, and at the moment, a display interface of the terminal presents prompt information of 'target backup data is being searched', so that a user is informed of waiting for a search result; further, as shown in fig. 3-1, after the data processing unit finds out target backup data having the same MD5 value as the target plug-in, the data processing unit prompts the user to confirm whether to immediately run the target backup data, such as decompressing the target backup data, and then run the target plug-in; or, as shown in fig. 3-2, when the data processing unit does not find the target backup data with the same MD5 value as the target plug-in, the data processing unit prompts the user to "find no target backup data", and simultaneously prompts the user to "whether to download the target backup data".
In this embodiment, as shown in fig. 8, the terminal further includes: a detection unit 76; wherein,
the detecting unit 76 is configured to detect whether the target communication network can be accessed;
the data processing unit 74 is further configured to, when the target communication network is not accessed, search whether target backup data matching the target characteristic value exists in the stored backup data corresponding to the target plug-in.
Specifically, the method comprises the following steps:
the application scene one:
the detection unit can also detect whether the target communication network can be accessed by the detection unit, for example, whether the target communication network can be accessed by the detection unit, and when the target communication network cannot be accessed, the data processing unit can search the stored backup data corresponding to the target plug-in unit for whether the target backup data matched with the target characteristic value exists, so that a foundation is laid for the terminal to be capable of quickly operating the target plug-in unit, a foundation is laid for multiplexing the backup data, and a foundation is laid for improving user experience.
Further, when the terminal fails to access a target communication network, such as Wi-Fi, and when the search result indicates that no target backup data matched with the target feature value exists, the terminal may generate a prompt message as shown in fig. 6 to prompt that the user is not currently located in Wi-Fi but in a mobile network, and then immediately download is selected according to the user requirement, or download of the target backup data is cancelled, so that direct download of the target backup data is avoided, a foundation is laid for saving traffic of the user, and user experience is improved.
Further, when the detection unit determines that the terminal can access the target communication network, such as can access Wi-Fi, and when the search result indicates that target backup data matching the target characteristic value does not exist, such as target backup data having backup identification information identical to the MD5 value of the target plug-in is not found from backup data corresponding to the target plug-in, the data processing unit may download the target backup data using the target communication network, so that a user is prevented from downloading the target backup data using mobile data, traffic is saved for the user, and user experience is improved.
Application scenario two:
the terminal searches whether target backup data matched with the target characteristic value exist in stored backup data corresponding to the target plug-in; when the search result represents that the target backup data matched with the target characteristic value exists, the detection unit does not need to detect whether the target communication network can be accessed or not; when the search result indicates that the target backup data matched with the target characteristic value does not exist, the detection unit detects whether the target communication network can be accessed, and then when the target communication network can be accessed, such as Wi-Fi can be accessed, the target communication network is used for downloading the target backup data; when the target communication network cannot be accessed, such as Wi-Fi, the prompt message shown in fig. 6 is generated, or the prompt message shown in fig. 3-2 is generated, that is, "target backup data is not found, and whether the target backup data is downloaded or not".
Therefore, compared with the mode that the existing plug-in mechanism only simply checks the file name to judge whether the backup data is available or not and further determines whether the backup data is compatible or not after the backup data is determined to be available, the embodiment of the invention can find out the target backup data which is available for the target plug-in and compatible with the target plug-in through one-time searching process, thereby reducing the searching flow, enabling the searching process to be fast, improving the searching efficiency and further improving the user experience.
Moreover, when the target plug-in is updated or the data is lost, the terminal according to the embodiment of the present invention does not need to directly delete the backup data corresponding to the target plug-in before updating, and first searches whether the available target backup data exists in the backup data corresponding to the target plug-in before updating, and then determines the next operation according to the search result, for example, when the target backup data exists, the target backup data is multiplexed, and then the target plug-in is operated, and when the target backup data is not found, the user is informed to download the target backup data.
