Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

The embodiment of the present application discloses a method for uploading files, which prevents system image files from being repeatedly submitted to the server.

Referring to FIG. 1, a flow chart of a file upload method shown according to an exemplary embodiment, as shown in FIG. 1, includes:

S101: Perform a fragmentation operation on the image file of the system according to a preset fragmentation rule to obtain multiple fragmented files;

The execution subject of this embodiment is a browser, and the purpose is to upload the image file of the system to the server. In this embodiment, the browser and the server support uploading in fragments, and developers can formulate the fragmentation rules of the image file, that is, the preset fragmentation rules in this step, for example, the fragmentation size of the image file of 1G, and Fragment start and end identifiers. On the browser side, the image file of the system is fragmented according to the preset fragmentation rules mentioned above, and the result is multiple fragmented files.

S102: Extracting target fragment files from all the fragment files, and calculating a check value corresponding to each of the target fragment files;

Since the contents of the image files of the system are basically the same under the same version, the image files of different versions and different systems are very different, so the content verification can be carried out by sampling. In this step, all fragmented files are sampled to obtain target sampled files, and a check value corresponding to each target fragmented file is calculated. It should be noted that the specific form of the check value is not limited here, for example, it may be an MD5 value.

It should be noted that this embodiment does not limit the specific sampling method, and a preset number of slice files may be extracted from all the slice files as target slice files. Preferably, the step of extracting the target slice file from all the slice files includes: extracting the first slice file and the last slice file of the image file as the target slice file; obtaining accurate degree, and calculate the extraction quantity according to the accuracy; wherein, the extraction quantity is the product of the accuracy and the quantity of all the fragment files; extract the target of the extraction quantity in all the fragment files Shard files.

In a specific implementation, the first fragment file and the last fragment file of the image file are extracted, a sampling number of indexes are randomly generated, and the fragment files corresponding to the indexes are extracted as target fragment files. That is to say, the target segment file includes the first segment file, the last segment and a randomly selected number of segment files, and the number of target segment files is the sampling number plus two. The accuracy can be adjusted according to actual needs. If the actual required accuracy is higher, the accuracy can be improved by increasing the ratio of the number of target fragment files to the number of all fragment files.

In order to improve the efficiency of detecting whether the image file exists in the server, duplicate name detection can be performed before content verification. That is, before this step, it also includes: sending the system name of the system and the file name of the image file to the server, so that the server can confirm whether there is a file with the same name, and generate a second confirmation result to return to the Browser; if the second confirmation result is that it does not exist, execute this step. In specific implementation, when a user requests to upload a mirror image file, the browser first requests the server to perform duplicate name detection. If there is a duplicate name file, the upload request is directly prohibited, and a prompt message is output to remind the user that the mirror file already exists.

S103: Send all the check values to the server, so that the server can confirm whether the same check value exists, and generate a first confirmation result and return it to the browser;

This step is to verify the content of the image file in the previous step to determine whether there is an image file with the same content as the image file on the server side, so as to avoid repeated uploads. Specifically, the browser sends the verification value of the target segment file calculated in the previous step to the server to request content verification from the server, and the server confirms that the same verification value is stored for the duration and returns the confirmation result to the browser.

S104: If the first confirmation result is that it does not exist, upload all the fragment files to the server, so that the server can calculate and store the check values corresponding to all the fragment files, and upload all the fragment files The fragmented files are merged into the image file.

In a specific implementation, if the same verification value does not exist in the server, it means that the image file is uploaded to the server for the first time. After the server receives all the fragmented files, it first calculates the verification value of all the fragmented files, stores them with the system name plus the version number as the unique identifier, and then merges all the fragmented files to obtain a complete image file.

S105: If the first confirmation result is that the image file exists, output a prompt message that the image file already exists.

In specific implementation, if there is the same verification value in the server, it means that the image file has been uploaded to the server. To avoid repeated uploads, this upload request is prohibited, and a prompt message is output to remind the user that the image file already exists.

The file upload method provided by the embodiment of the present application compares the contents of the file before uploading the image file of the system to ensure that only one copy of the image file with the same content is saved on the server, which avoids the storage usage of the server caused by multiple uploads of the same file. Too many and multiple uploads cause the problem that the server bandwidth is too large and the load is too large. In addition, all the fragmented files are sampled to obtain the target fragmented files, and the verification value of the target fragmented files is used to compare the file content, which avoids the problem of too slow and low efficiency in obtaining the verification value of the entire image file.

The embodiment of the present application discloses a file uploading method. Compared with the previous embodiment, this embodiment further explains and optimizes the technical solution. specific:

Referring to FIG. 2 , a flow chart of another file uploading method shown according to an exemplary embodiment, as shown in FIG. 2 , includes:

S201: Perform a fragmentation operation on the image file of the system according to a preset fragmentation rule to obtain multiple fragmented files;

S202: Send the system name of the system and the file name of the image file to the server, so that the server can confirm whether there is a file with the same name, if so, go to S206; if not, go to S203;

S203: Extract target fragment files from all the fragment files, and calculate a check value corresponding to each target fragment file;

S204: Send all the check values to the server, so that the server can confirm whether there is the same check value, if yes, go to S206; if not, go to S205;

S205: Upload all the fragmented files to the server, so that the server calculates and stores check values corresponding to all the fragmented files, and merges all the fragmented files into the mirror image file.

S206: Output prompt information that the image file already exists.
