In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Referring to fig. 1, which is a schematic flowchart of a method for obtaining an upgrade file according to an embodiment of the present invention, where the method is applied to a server, and as shown in the figure, the method may include the following steps:
step S101, after receiving a first request message for an application sent by a terminal, obtaining an upgrade file of the application, and splitting the upgrade file into a plurality of sub-upgrade files.
In the embodiment of the present invention, after receiving a first request message for an application sent by a terminal, the server may obtain an upgrade file for the application from a memory of the server, and split the upgrade file into a plurality of sub-upgrade files, where the sizes of the plurality of sub-upgrade files may be equal or unequal, and are not limited herein. The certain application may be any application installed in the terminal (for example, WeChat, QQ, Taobao, etc.), the first request information is information requesting the server to send an upgrade file, and the first request information may be generated by triggering a virtual button on the terminal screen, for example, clicking a virtual button on a mobile phone screen, where text information for WeChat is "update".
Optionally, the splitting the upgrade file into a plurality of sub-upgrade files includes:
acquiring network transmission parameters when the server sends a preset file to the terminal;
and splitting the upgrading file into a plurality of sub upgrading files according to the network transmission parameters.
Specifically, before sending the sub-upgrade file to the terminal, the server may send a predetermined file (the predetermined file is a preset file for network transmission test) to the terminal, so as to execute the network transmission test between the server and the terminal, obtain network transmission parameters such as a network transmission speed and a packet loss rate when the server sends the predetermined file to the terminal, and split the upgrade file according to the obtained network transmission parameters. For example, when the network transmission speed is relatively fast (e.g., 200mbps) and the packet loss rate is relatively low (e.g., 5%), the number of sub-upgrade files split from the upgrade file may be reduced (i.e., each sub-upgrade file is relatively large), and when the network transmission speed is relatively slow (e.g., 0.1mbps) and the packet loss rate is relatively high (e.g., 20%), the number of sub-upgrade files split from the upgrade file may be increased (i.e., each sub-upgrade file is relatively small). Optionally, the server may also split the upgrade file into a fixed number of sub upgrade files, for example, five sub upgrade files, which is not limited herein.
Optionally, in order to facilitate that the terminal knows the sequence of each sub-upgrade file in the plurality of sub-upgrade files after receiving the plurality of sub-upgrade files, after splitting the upgrade file into a plurality of sub-upgrade files, the embodiment of the present invention further includes:
and adding a corresponding file serial number identifier at a preset position of each sub-upgrading file in the plurality of sub-upgrading files so as to determine the sequence of each sub-upgrading file in the plurality of sub-upgrading files.
Wherein the predetermined location includes, but is not limited to, the beginning or end of a child upgrade file.
Step S102, according to each sub-upgrading file in the plurality of sub-upgrading files, generating a digital abstract corresponding to each sub-upgrading file.
In this embodiment of the present invention, the server may apply a specific algorithm (e.g., a hash algorithm) to each sub-upgrade file to generate a digital digest corresponding to each sub-upgrade file, where each sub-upgrade file corresponds to its corresponding digital digest one to one.
Illustratively, the server divides the upgrade file a of the WeChat into five sub-upgrade files, which are respectively a1, a2, A3, a4 and a5, the server may generate a digital digest H1 corresponding to the sub-upgrade file a1 by using a hash algorithm, generate a digital digest H2 corresponding to the sub-upgrade file a2 by using a hash algorithm, generate a digital digest H3 corresponding to the sub-upgrade file A3 by using a hash algorithm, generate a digital digest H4 corresponding to the sub-upgrade file a4 by using a hash algorithm, and generate a digital digest H5 corresponding to the sub-upgrade file a5 by using a hash algorithm.
In this embodiment of the present invention, the server may store the digital digests in the sub-upgrade files corresponding to the digital digests (for example, at the beginning or the end of the sub-upgrade file), or store one digital digest separately as an independent file, or store the digital digests of all the sub-upgrade files in a merged manner as one file, which is not limited herein.
Step S103, sending each sub-upgrade file to the terminal, so that the terminal obtains a digital abstract corresponding to each sub-upgrade file generated in the server after receiving each sub-upgrade file, generates a digital abstract corresponding to each sub-upgrade file in the terminal according to each sub-upgrade file, compares the digital abstract with the digital abstract corresponding to each sub-upgrade file generated in the server, stores the sub-upgrade files if the digital abstract is the same as the digital abstract, and splices all the sub-upgrade files into the upgrade file after storing all the sub-upgrade files.
In this embodiment of the present invention, the server sends each of the plurality of sub-upgrade files to the terminal, so that after receiving each of the sub-upgrade files, the terminal generates a digital digest corresponding to each of the received sub-upgrade files by using a specific algorithm (for example, a hash algorithm) that is the same as that used when generating the digital digest corresponding to each of the sub-upgrade files in the server.
Illustratively, the server adopts a hash algorithm when generating the digital digest H1 corresponding to the sub-upgrade file a1, and after receiving the sub-upgrade file a1, the terminal also adopts the hash algorithm to generate the digital digest L1 corresponding to the sub-upgrade file a1, compares the digital digest L1 with the digital digest H1, and if the digital digest L1 is the same as the digital digest H1, determines that the sub-upgrade file a1 is complete (i.e., no error), and saves the sub-upgrade file a 1; if the sub-upgrade file A1 is not complete (for example, an error byte exists in the sub-upgrade file A1), the terminal sends retransmission request information for the sub-upgrade file A1 to the server, after receiving the retransmission request information, the server obtains the sub-upgrade file A1 from the server memory and resends the sub-upgrade file A1 to the terminal, so that the terminal is ensured to receive the complete sub-upgrade file A1.
The server may sequentially send the plurality of sub-upgrade files to the terminal, or may simultaneously send the plurality of sub-upgrade files in parallel, which is not limited herein.
In the embodiment of the invention, the upgrading file is split into a plurality of sub-upgrading files in the server, a digital abstract is independently generated for each sub-upgrading file, after the terminal receives each sub-upgrading file, and a digital abstract is also generated separately for each sub-upgrade file at the terminal, and when the digital abstract is the same as the digital abstract generated in the server, the sub-upgrade file corresponding to the digital abstract is determined to be a complete sub-upgrade file, and the sub-upgrade file is saved, after the terminal receives all the sub-upgrade files, all the sub-upgrade files are spliced into the upgrade file, thereby ensuring that the terminal can acquire the correct upgrade file, when the digital abstract is different from the digital abstract generated in the server, and the sub-upgrade file corresponding to the digital abstract is determined to have an error, only the sub-upgrade file needs to be retransmitted, so that the size of the retransmitted file is reduced.
Referring to fig. 2, which is a schematic flowchart of a method for acquiring an upgrade file according to a second embodiment of the present invention, where the method is applied to a terminal, and as shown in the figure, the method may include the following steps:
step S201, sending a first request message for an application to a server, so that the server obtains an upgrade file of the application after receiving the first request message, splits the upgrade file into a plurality of sub-upgrade files, generates a digital summary corresponding to each sub-upgrade file according to each sub-upgrade file in the plurality of sub-upgrade files, and sends each sub-upgrade file to the terminal.
In the embodiment of the present invention, the terminal sends a first request message for a certain application to a server, so that after receiving the first request message, the server can obtain an upgrade file for the application from a memory of the server, split the upgrade file into a plurality of sub-upgrade files, generate a digital digest corresponding to each sub-upgrade file by using a specific algorithm (for example, a hash algorithm) for each sub-upgrade file, and send each sub-upgrade file to the terminal, where each sub-upgrade file corresponds to its corresponding digital digest one to one. The certain application may be any application (e.g., WeChat, QQ, Taobao, etc.) installed in the terminal, the first request information is information for requesting a server to send an upgrade file, the first request information may be generated by triggering a virtual button on the terminal screen, for example, clicking a virtual button on a mobile phone screen, where text information for WeChat is "update", and the server may send the multiple sub-upgrade files to the terminal in sequence, or may send the multiple sub-upgrade files in parallel at the same time.
Illustratively, the server divides the upgrade file a of the WeChat into five sub-upgrade files, which are respectively a1, a2, A3, a4 and a5, the server may generate a digital digest H1 corresponding to the sub-upgrade file a1 by using a hash algorithm, generate a digital digest H2 corresponding to the sub-upgrade file a2 by using a hash algorithm, generate a digital digest H3 corresponding to the sub-upgrade file A3 by using a hash algorithm, generate a digital digest H4 corresponding to the sub-upgrade file a4 by using a hash algorithm, and generate a digital digest H5 corresponding to the sub-upgrade file a5 by using a hash algorithm.
In this embodiment of the present invention, the server may store the digital digests in the sub-upgrade files corresponding to the digital digests (for example, at the beginning or the end of the sub-upgrade file), or store one digital digest separately as an independent file, or store the digital digests of all the sub-upgrade files in a merged manner as one file, which is not limited herein.
Optionally, in order to facilitate that the terminal knows the sequence of each sub-upgrade file in the plurality of sub-upgrade files after receiving the plurality of sub-upgrade files, the server may first add a file sequence number identifier to each sub-upgrade file, and then send the sub-upgrade file to which the file sequence number identifier has been added to the terminal.
It should be noted that, if the server adds a file serial number identifier to each sub-upgrade file, when generating a corresponding digital digest for each sub-upgrade file, the sub-upgrade file to which the file serial number identifier has been added is generated into a digital digest corresponding to the sub-upgrade file by using a specific algorithm.
Step S202, after receiving each sub-upgrade file sent by the server, acquiring a digital abstract generated in the server and corresponding to each sub-upgrade file.
For example, after receiving the sub-upgrade file a1 sent by the server, the terminal sends request information for the digital digest of the sub-upgrade file a1 to the server, and after receiving the request information, the server obtains the digital digest H1 corresponding to the sub-upgrade file a1 from the server memory and sends the digital digest H1 to the terminal.
Step S203, according to each sub-upgrading file, generating a digital abstract corresponding to each sub-upgrading file in the terminal, and comparing the digital abstract with the digital abstract corresponding to each sub-upgrading file generated in the server.
In this embodiment of the present invention, after receiving each sub-upgrade file, the terminal generates a digital digest corresponding to each received sub-upgrade file by using a specific algorithm (for example, a hash algorithm) that is the same as that used when generating the digital digest corresponding to each sub-upgrade file in the server. For example, the server generates the digital digest H1 corresponding to the sub-upgrade file a1 by using a hash algorithm, and the terminal also generates the digital digest L1 corresponding to the sub-upgrade file a1 by using the hash algorithm after receiving the sub-upgrade file a 1.
And step S204, if the sub-upgrade files are the same, saving the sub-upgrade files, and splicing all the sub-upgrade files into the upgrade file after saving all the sub-upgrade files.
In this embodiment of the present invention, the splicing the all sub-upgrade files into the upgrade file may specifically be: and splicing all the sub-upgrading files into the upgrading file according to the file serial number identifications in all the sub-upgrading files and the sequence of each sub-upgrading file in all the sub-upgrading files.
It should be noted that, in the process of splicing all the sub-upgrade files into the upgrade file, the file serial number identifier in each sub-upgrade file needs to be removed first, and then the sub-upgrade files with the file serial number identifiers removed are spliced.
Optionally, the embodiment of the present invention further includes:
if the digital abstract corresponding to a certain sub-upgrade file generated in the terminal is different from the digital abstract corresponding to the sub-upgrade file generated in the server, transmitting retransmission request information aiming at the sub-upgrade file to the server, so that the server acquires the sub-upgrade file after receiving the retransmission request information and retransmits the sub-upgrade file to the terminal.
Illustratively, after receiving the sub-upgrade file a1, the terminal generates a digital digest L1 corresponding to the sub-upgrade file a1 by using a hash algorithm, compares the digital digest L1 with the digital digest H1, and if the digital digest L1 and the digital digest H1 are the same, determines that the sub-upgrade file a1 is complete (i.e., no error), and saves the sub-upgrade file a 1; if the sub-upgrade file A1 is not complete (for example, an error byte exists in the sub-upgrade file A1), the terminal sends retransmission request information for the sub-upgrade file A1 to the server, after receiving the retransmission request information, the server obtains the sub-upgrade file A1 from the server memory, and resends the sub-upgrade file A1 to the terminal, so that the terminal is guaranteed to receive the complete sub-upgrade file A1.
The method and the device have the advantages that after the terminal receives each sub-upgrade file in the plurality of sub-upgrade files, a digital abstract is independently generated for each sub-upgrade file at the terminal, the sub-upgrade file corresponding to the digital abstract is determined to be a complete sub-upgrade file when the digital abstract is the same as the digital abstract generated in the server, the sub-upgrade file is stored, all the sub-upgrade files are spliced into the upgrade file after the terminal receives all the sub-upgrade files, so that the terminal can acquire the correct upgrade file, when the digital abstract is different from the digital abstract generated in the server, the sub-upgrade file corresponding to the digital abstract is determined to be wrong, only the sub-upgrade file needs to be retransmitted, the whole upgrade file does not need to be retransmitted, and the size of the retransmitted file is reduced.
It should be understood that, in the above embodiments, the order of execution of the steps is not meant to imply any order, and the order of execution of the steps should be determined by their function and inherent logic, and should not limit the implementation process of the embodiments of the present invention.
