In order to facilitate understanding of the embodiments provided in the present application, the technical solutions in the embodiments of the present application are further described in detail below with reference to the accompanying drawings. Referring to fig. 2, fig. 2 is a flowchart of a method for downloading an upgrade package according to an embodiment of the present application. As an embodiment, the flow shown in fig. 2 may be applied to the display device as described above.
As shown in fig. 2, the process may include the following steps:
As an embodiment, the target upgrade information may be obtained from a backend server for providing the system upgrade service, where the backend server may be a server arranged in a cloud by a manufacturer. In the background server, various upgrade policies for upgrading the system, such as the name and size of the upgrade package used when upgrading the system from the first version to the second version, and a check value for identifying the upgrade package, may be saved.
Based on the introduction of the background server, when receiving an instruction message for upgrading the system from the first version to the second version, the target upgrade package information of the target upgrade package required for upgrading the system from the first version to the second version may be acquired from the background server.
It should be noted that the check value for identifying the upgrade package is a unique identifier for upgrading the upgrade package of the system, that is, the check value corresponding to each upgrade package is different, for example, the check value corresponding to the upgrade package for upgrading the system from the first version to the second version is different from the check value corresponding to the upgrade package for upgrading the system from the second version to the third version. Further, the check value may be implemented in various ways, for example, an MD5 value may be determined for each upgrade package by using an MD5 algorithm, and the MD5 value of each upgrade package is different.
As an embodiment, based on that the file suffix of the upgrade package which has completed downloading is different from the file suffix of the upgrade package which has not completed downloading, for example, the file suffix of the upgrade package which has completed downloading may be.zip or.rar, while the file suffix of the upgrade package which has not completed downloading is.tmp, it may be determined whether each upgrade package is the upgrade package for the upgrade system which has completed downloading by obtaining the file suffix of each upgrade package downloaded in the download directory.
In this embodiment of the present application, if the target upgrade package information at least includes a target upgrade package name, a target upgrade package size, and a check value for identifying the target upgrade package, when there is an upgrade package that has completed downloading in the download directory, the size of each upgrade package that has completed downloading and the check value configured in each upgrade package may be calculated, and then, for each upgrade package that has completed downloading, the name, size, and check value of each upgrade package that has completed downloading are detected to determine whether the name, size, and check value of each upgrade package that has completed downloading are consistent with the target upgrade package name, target upgrade package size, and check value for identifying the target upgrade package included in the target upgrade package information.
It should be noted that, in the embodiment of the present application, the check value of the upgrade package calculated under the condition that the upgrade package is completely downloaded is consistent with the check value corresponding to the upgrade package stored in the background server.
Further, in this embodiment of the present application, if it is detected that upgrade package information of any upgrade package that has been downloaded is consistent with the target upgrade package information, it may indicate that the target upgrade package required for upgrading the system from the first version to the second version has been downloaded before the display device is turned on this time, and then it may be started to check whether the target upgrade package is available.
Optionally, in the verification process of the target upgrade package, referring to an interface shown in fig. 3, a prompt message used for prompting that the target upgrade package is downloaded before the start-up of the display device and is currently being verified is popped up on a display screen of the display device, and the progress of verification execution is displayed, so as to determine the progress of system upgrade.
As an embodiment, if it is detected that the upgrade package information of all the upgrade packages that have completed downloading is inconsistent with the target upgrade package information, the obtained upgrade packages that have completed downloading may be deleted, and the target upgrade package is downloaded again from the background server in the cloud through the OTA technology, and referring to the interface shown in fig. 4, a prompt message for prompting that the target upgrade package is being downloaded is popped up on the display screen of the display device, and the downloading progress of the target upgrade package is displayed.
In this embodiment of the present application, when a target upgrade package is downloaded again, a temporary file is newly created in the device, a file suffix of the temporary file is a file suffix used for indicating that the target upgrade package is not downloaded, and the name of the target upgrade package obtained from the backend server is used as a name of the temporary file, where the target upgrade package downloaded in this embodiment is to be stored in the temporary file. Further, when the target upgrade package finishes downloading, the file suffix of the temporary file is modified to a file suffix used for indicating that the target upgrade package finishes downloading, such as modifying the file suffix of the temporary file from tmp to zip.
As an embodiment, when an incomplete downloaded upgrade package for system upgrade does not exist in the current download directory, a target upgrade package may be downloaded from a background server in the cloud, and an interface as shown in fig. 4 is displayed through a display screen of the device.
In this embodiment of the present application, when there is an incomplete download upgrade package, the size of each incomplete download upgrade package may be calculated first, and the size of each incomplete download upgrade package is compared with the size of the target upgrade package, where if there is an incomplete download target upgrade package in the incomplete download upgrade packages, the size of the incomplete download target upgrade package should be smaller than the size of the target upgrade package because the target upgrade package is not completed download.
Optionally, when it is detected that the size of one unfinished downloaded upgrade package is smaller than the size of the target upgrade package, it may be further detected whether the name of the unfinished downloaded upgrade package is consistent with the name of the target upgrade package, and in the case of consistency, it is determined that the unfinished downloaded upgrade package is the unfinished downloaded target upgrade package.
Optionally, when the target upgrade package which is not downloaded is continuously downloaded, a prompt message for prompting that the target upgrade package is not downloaded before the start-up of the display device is popped up on a display screen of the display device with reference to an interface shown in fig. 5, and the target upgrade package is continuously downloaded at present, and the downloading progress of the target upgrade package is displayed. As to how to continue downloading the target upgrade package which is not downloaded, the breakpoint resume function in the related art may be referred to, which is not described herein again.
As an embodiment, after the target upgrade package that has not been downloaded in step 205 completes downloading, the file suffix of the target upgrade package recorded in the present apparatus may be modified from the file suffix used for indicating that the target upgrade package has not completed downloading to the file suffix used for indicating that the target upgrade package has completed downloading, such as modifying the file suffix of the target upgrade package that has not completed downloading from.
It should be noted that, in the embodiment of the present application, if there is no unfinished downloaded target upgrade package corresponding to the target upgrade package information in the unfinished downloaded upgrade package, the currently stored unfinished downloaded upgrade package may be deleted, the target upgrade package is re-downloaded from the background server by the OTA technology, and the interface shown in fig. 4 is displayed.
Thus, the flow shown in fig. 2 is completed.
Through the embodiment shown in fig. 2, it is possible to search whether there is an upgrade package already downloaded or an upgrade package not yet downloaded corresponding to the target upgrade package information from the currently recorded download directory by obtaining the target upgrade package information of the target upgrade package required for upgrading the system from the first version to the second version, and when there is an upgrade package already downloaded corresponding to the target upgrade package information, the upgrade package may be directly used as the target upgrade package to implement system upgrade without re-downloading the target upgrade package, and when there is an upgrade package not yet downloaded corresponding to the target upgrade package information, the complete target upgrade package may be obtained by continuing to download based on the upgrade package not yet downloaded, without re-downloading the entire target upgrade package, thereby saving network resources.
It should be noted that, in the implementation process of the embodiment of the present application, the interface shown in fig. 3, or fig. 4, or fig. 5 displayed on the screen may be hidden in the background through a background-implemented button displayed on the interface, so as to prevent the interface from affecting the use of the display device during the upgrade process.
