S103, accessing a real path by using a preset file transfer protocol, and transmitting the object file to be downloaded corresponding to the real path to client equipment by using a pre-established transmission channel.
And when the internal program returns the real path of the object file to be downloaded, accessing the real path by using a preset file transmission protocol, and executing downloading through a transmission channel established in advance, thereby finally realizing that the whole object file to be downloaded is downloaded to the client equipment. In this embodiment, the pre-established transmission channel is a dedicated channel for downloading the object file, and specifically, a network card may be added to the object storage pool, and a network link corresponding to the network card is used to perform data exchange with a server having a preset file transfer protocol, so as to download the object file to be downloaded.
The present embodiment does not limit the preset file transfer protocol, and the user can customize the setting, as long as the purpose of the present embodiment can be achieved. In one implementation, accessing the real path using a predetermined file transfer protocol includes: the real path is accessed using FTP. FTP (File Transfer Protocol) is a method of establishing a connection between an FTP client device and an FTP server. The FTP client device may issue commands to the FTP server to download files, upload files, create or change directories on the server. In another implementation, accessing the real path using a predetermined file transfer protocol includes: the real path is accessed using SFTP. SFTP (Secure File Transfer Protocol) can provide a Secure encryption method for the transmitted File, and has high reliability. In another implementation, accessing the real path using a predetermined file transfer protocol includes: the real path is accessed using the SCP. SCP (Secure Copy protocol) is used for remote file copying and the entire copying process is encrypted. Data transmission uses SSH and SSH connection tunnels are secure using the same authentication method as SSH, and thus file transmission based on SCP protocol is secure. In another implementation, accessing the real path using a predetermined file transfer protocol includes: the real path is accessed using TFTP. Among them, TFTP (Trivial File Transfer Protocol) only supports File Transfer without verifying the authority of the client. Of course, other file transfer protocols are possible, and this embodiment is not limited.
Based on the technical scheme, after receiving a download request of the client device, the embodiment acquires the metadata information of the corresponding object file to be downloaded, acquires the real path according to the metadata information, accesses the real path of the object file to be downloaded by using a preset file transfer protocol, and downloads the object file to the client device by using the pre-established transmission channel.
Further, before receiving a download request from a client device, to determine the reliability of the file, the method further includes:
after the uploading of the object file to be downloaded is finished, performing hash calculation according to the attribute information of the object file to be downloaded to obtain a hash value;
generating metadata information according to the hash value;
determining a real path of the object file to be downloaded according to the metadata information, including:
analyzing the metadata information to obtain a corresponding hash value;
and determining the real path of the object file to be downloaded according to the hash value.
The server stores a plurality of object files, and when the object files are uploaded to the server, hash calculation is performed on attribute information of the object files to generate hash values. According to the method and the device, the uploading of the object file to be downloaded is explained, after the uploading of the object file to be downloaded is completed, the server receives the complete object file to be downloaded, and the swift performs hash calculation on attribute information of the object file to be downloaded, wherein the attribute information includes but is not limited to the name of the object file to be downloaded, the size of the file, a real path and the like, a hash value is finally obtained, metadata information is generated according to the hash value, and the metadata information includes the hash value, IP information, ID information and the like. Further, in the downloading process, after the metadata information is determined, the metadata information is analyzed to obtain a hash value, and if the hash value is successfully calibrated, a real path of the object file to be downloaded is obtained. Therefore, the reliability of the object file to be downloaded is ensured by the hash operation mode in the embodiment.
Further, the method also comprises the following steps: creating an object storage based on a file system, and starting a preset file transfer protocol service in a directory of an object storage pool or other directories containing the object storage directory; determining a directory stored by the object file as an external root directory of a preset file transfer protocol; correspondingly, accessing the real path by using a preset file transfer protocol includes: and accessing the real path in the root directory by using a preset file transfer protocol.
In this embodiment, an object storage is created based on a file system, a preset file transfer protocol service of a server is started under a directory of an object storage pool of an object or other directories including the object storage directory, and the directory stored by the object file is determined as a root directory, where the file stored by the object includes an object file to be downloaded and other object files, and the directory stored by the object file is the directory of the object storage pool or other directories including the object storage directory; and accessing the real path of the object file to be downloaded in the root directory by using a preset file transfer protocol, and finally downloading the object file to be downloaded. When downloading an object file to be downloaded, an internal program is first required to obtain real storage path information (real path) of the object file to be downloaded, and return the real path information to an upper layer caller (client device).
Based on any of the above embodiments, this embodiment provides a specific method for implementing object file downloading based on FTP, where the method first adds a dedicated channel (transmission channel) for downloading an object at an existing object storage end, and specifically implements adding a network card to an object storage pool, and performs data exchange using a network link corresponding to the network card and an FTP server to perform downloading of an object file to be downloaded; secondly, starting FTP service at an object storage terminal built on the basis of a file system, taking a root directory used by the object storage or other temporary directories as the externally exposed root directory of the FTP, when an object file to be downloaded is downloaded, firstly obtaining metadata information of the object file to be downloaded in the back-end object storage through an internal program, further inquiring information of a real path returned by the internal program after the real path stored by the object file to be downloaded is stored according to the metadata information, and accessing the real path of the object file to be downloaded by using an FTP protocol and downloading the real path so as to finish the downloading of the whole object file to be downloaded. It can be understood that after the object storage finishes uploading the object file to be downloaded, the swift performs hash calculation according to the attribute information of the object file to be downloaded, generates the real storage position and name of the file in the object storage, downloads the object file to be downloaded to the root directory to which the object storage belongs through the FTP protocol, wherein the specific information of the object file to be downloaded includes the size, MD5, meta data information, then calls the download interface of the object storage, records the real path of the object file to be downloaded in the object storage pool according to the information returned by the download interface, and finally downloads the file according to the real path when downloading the file.
It can be seen that, in this embodiment, an object storage is established based on a file system, a dedicated internet access is added to the object storage end to perform data exchange with an external FTP client, when the FTP client downloads an object file to be downloaded through an FTP protocol, a real path of the object file to be downloaded is queried through an internal program, and then the FTP protocol is used to access a real location of the file and perform downloading. The embodiment can solve the problems that the downloading object occupies the object storage bandwidth and strongly depends on the interaction between the object storage client and the server, and the size of the file is not limited by the FTP downloading, so the embodiment can also solve the problem of the limitation of the size of the downloaded file 5G.
