Under every other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to FIG. 1, Fig. 1 is a kind of implementation flow chart of the method for OVA file upload services device in the present invention, the OVA
The method of file upload services device may comprise steps of:
Step S101: after receiving the uploading instructions for OVA file, the communication channel with server is established.
The method of OVA file upload services device described herein can be applied to any one master connecting with server
In generator terminal.Host side can receive the uploading instructions for OVA file of user's transmission, will include on needs in the uploading instructions
The information such as the file name of the OVA of biography.
OVA file is made of multinomial subfile, in most of occasion, by virtual disk files, and OVF file and mf text
Part is constituted.It is emphasized that OVA file is made of multinomial subfile, it is not to say that and these subfiles is placed in a file
Just OVA file is constituted in folder, but needs to compress these subfiles according to preset format, compressed compressed package
File as OVA format.
Host side needs to establish the communication channel with server after receiving the uploading instructions for OVA file.In
When it is implemented, an OVAGenerator can be maintained in the memory of host side, this Shen is executed by OVAGenerator
Each step please.It, can be in IP, port, the user of host side input server when establishing the communication channel with server
The information such as name and login password, realize the foundation of communication channel.
The communication protocol that server is taken is different, and the communication channel of foundation can be adaptably different.Such as work as server
When for FTP (File Transfer Protocol, File Transfer Protocol) server, the transmission channel that host side is established can be
FTP Socket transmission channel.Certainly, there can also be the server of other forms in other occasions, but it should be recognized that
It is usually that sharing for OVA file is carried out by ftp server, i.e. the scheme of the application is usually applied to the occasion of ftp server
In.
Step S102: according to preset order, target subfile is selected from every subfile to be uploaded.
Preset sequence can arbitrarily be set in advance by staff, and be can according to need and be adjusted, such as set
Fixed sequence are as follows: preferentially upload virtual disk files, i.e., preferentially select virtual disk files as target subfile, Zhi Houshang
OVF file is passed, mf file is finally uploaded, i.e., after virtual disk files upload finishes, chooses OVF file as target Ziwen
Part finally chooses mf file as target subfile.For another example, preset sequence are as follows: preferential OVF file of choosing is as target Ziwen
Part, later mf file, last virtual disk files.
Step S103: the metadata information and boil down to OVA format of target subfile to be uploaded are obtained, and utilizes communication
Channel is uploaded to server.
Such as the target subfile selected is virtual disk files, then needs to obtain the metadata letter of virtual disk files
Breath.
Metadata information mainly includes file name, size, permission control, uname, gname, the creation of file, modification
The information such as time, namely constitute the File Header information of this subfile.The organized formats of OVA file can be shown in Table one.
Table one:
| File Header | File Content | …… | File Header | File Content |
When OVA file is made of three subfiles, then File Header is partially and three corresponding there are three tool
The part File Content.
After the metadata information for obtaining target subfile, boil down to OVA format is needed, and using in communication channel
Reach server.When uploading metadata information, due to memory and the rate limitation of network transmission, need according to file stream,
Or the mode of referred to as data flow is transmitted, i.e., transmits a part of data every time, realizes complete first number by being transmitted several times
It is believed that the upload of breath, uploads file content in subsequent step, i.e. when upload File Content is also such.
It should also be noted that, when uploading data every time, it usually needs added according to the Data Transport Protocol of server
Dependent instruction, so that the OVA file that server storage host side uploads.Indicate that server execution connects by dependent instruction
The storage of the OVA file of receipts operates.And it is possible to the description to the data of upload be added in each instruction, so that server
The location of the data got every time can be known, in general, size of data, data can be added for the data uploaded every time
The description of title and data start.
Step S104: the file content of target subfile, and the text that will be got every time are obtained in the way of file stream
Part content compression be OVA format after, be uploaded to server using communication channel.
After the File Header for obtaining and uploading target subfile, then need to upload target subfile
File Content, i.e. upload file content.
The file content that target subfile is obtained in the way of file stream, the file content pressure for needing to get every time
It is condensed to OVA format and then is uploaded to server using communication channel.
When uploading file content, it is one and constantly obtains, the process constantly compressed and uploaded.The data volume obtained every time
It can according to need and set, in a specific embodiment, it is contemplated that uploading data, there are the limitations of network transmission, often
The secondary size for obtaining the file content that too many file content is easy to cause the accumulation of data to be uploaded, therefore obtains every time is set
It is set to lower than preset network transmission threshold limit.For example, network transmission threshold limit is 2,000,000, and setting is every in concrete scene
It is secondary obtain 1,000,000 file content, after being compressed with this 1,000,000 file content is uploaded to server.
Step S105: it returns and executes according to preset order, select target subfile from every subfile to be uploaded
Operation, until OVA file in every subfile be selected it is primary be used as target subfile, to complete OVA file
It uploads.
After finishing the upload of any one subfile, it is required to judge whether there is also to be uploaded in OVA file
Subfile.If it is present return step S102, every subfile when subfile not to be uploaded, i.e., in OVA file
When being selected primary conduct target subfile, the upload of OVA file is just completed.
The usually available respective file initial position of every subfile for constituting OVA file of host side and file are big
It is small.When the upload of a certain item subfile finishes, by switching the initial position of reading of content, the switching of upload project is realized.
In the scheme of the application, a complete OVA file to be uploaded can't be formed in host side.Specifically, this
