In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
Referring to fig. 1, which is a schematic view of an implementation flow of a file integrity detection method provided in an embodiment of the present application, as shown in the figure, the file integrity detection method may include the following steps:
step S101, before downloading a first file from a server, downloading a start mark file and an end mark file of the first file.
Wherein, the first file is a file to be downloaded from the server. The start flag file and the end flag file are used to indicate whether the first file is complete, the start flag file and the end flag file may be files including flag information, the flag information in the start flag file and the flag information in the end flag file are the same, the flag information is used to indicate whether the first file is complete, the flag information may be set by a user, or may be automatically generated when the terminal device uploads the start flag file of the first file to the server, for example, when the terminal device uploads the start flag file of the first file to the server, the current time information of the terminal device (i.e., the time when the start flag file is uploaded) is obtained, and the current time information is used as the flag information in the start flag file and the end flag file. The server includes, but is not limited to, a File Transfer Protocol (FTP) server, where the FTP server is a computer providing File storage and access service on the internet, and a user may use a terminal device to remotely access the FTP server through the network to download a File stored in the FTP server according to the FTP service.
In the embodiment of the application, the terminal device uploads the start marker file and the end marker file of the first file while uploading the first file to the server, and detects whether the first file stored in the server is complete through the start marker file and the end marker file, that is, detects whether the first file uploaded to the server by the terminal device is complete.
In this embodiment of the present application, a terminal device may send first file downloading request information to a server, and after receiving the first file downloading request information, the server feeds back a start flag file and an end flag file of the first file to the terminal device, and if the start flag file and the end flag file of the first file are received within a preset time, it is determined that both the start flag file and the end flag file of the first file are successfully downloaded; if any one of the start marker file and the end marker file of the first file is not received within the preset time, it is determined that the downloading of the file (i.e., the file which is not received) fails, the file may not exist in the server, the first file may be incomplete, and at this time, a prompt message may be sent to the server to prompt that the first file is incomplete through the prompt message. The preset time is used for judging whether the file is successfully downloaded from the server, and the preset time can be set by the user, which is not limited herein.
It should be noted that, in order to avoid a file download failure caused by a network reason, before downloading a start flag file and an end flag file of a first file from a server, a network to which a terminal device is currently connected is detected, and an RSSI (Received Signal Strength Indication) value of a Received Signal of the network to which the terminal device is currently connected is obtained, and when the RSSI value of the network to which the terminal device is currently connected is greater than or equal to a preset threshold, the terminal device may communicate with the server through the currently connected network, for example, upload a file to the server or download a file from the server through the currently connected network; when the RSSI value of the network to which the terminal equipment is currently connected is smaller than the preset threshold value, the network to which the terminal equipment is currently connected can be switched to the network with the RSSI value larger than the preset threshold value, so that the network is kept stable when the terminal equipment is communicated with the server.
Step S102, if the start mark file and the end mark file are both downloaded successfully, detecting whether the content of the start mark file is the same as the content of the end mark file.
In this embodiment, if the terminal device successfully downloads the start flag file and the end flag file from the server, it may determine whether the first file is complete by detecting whether the content of the start flag file is the same as the content of the end flag file (i.e., detecting whether the flag information in the start flag file is the same as the flag information in the end flag file).
