Detailed description of the invention
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
In practice, the multimedia data resources of backstage configuration would generally swap between a client and a server, generally speaking, described client and server carry out the mode of multimedia data resources exchange two kinds: a kind of is that client is local image and sound files passe, to store under certain field in database table in the way of data base, in data base, namely insert image and sound; Another kind is these images in client-access data base and sound, namely takes out these images and sound from data base.
Respectively above-mentioned exchanged form will be described in detail by different embodiments below.
With reference to Fig. 1, it is shown that the flow chart of the storage embodiment of the method for a kind of multimedia file of the present invention, specifically may comprise steps of:
Step 101, request multimedia file uploaded onto the server by client submission;
Corresponding multimedia file, according to described request, is converted to flow object, and stores to data base by step 102, server.
In implementing, the multimedia file upload request that described server can be submitted to according to client, extract corresponding multimedia file, and for described multimedia file allocation field name, field type and file type information, be then store as corresponding data-base recording.
It should be noted that in embodiments of the present invention, described flow object refers to binary stream, such as binary system array (byte []); Described field type is stream file type.
In practice, arranging data base in the server can be SQLServer data base, then the field type of described multimedia file can represent by Image type; As another embodiment, if data base in the server can be oracle database, then the field type of described multimedia file can represent by Blob type.
Below for oracle database, illustrate the storage organization of multimedia file of the present invention. Assume to set present image file, audio files storage under Value field, as shown in table 1:
Table 1:
| Field name | Field type | Whether it is empty | Explanation |
| Resid | Varchar(50) | Not Null | The name of image or sound |
| Value | Blob | Null | Storage image or sound |
| Type | Int(4) | Not null | Type judges that 0 as picture, 1 sound |
After the upload request submitting a switch picture file to, the respective record that server preserves in data base is as shown in table 2:
| Resid | Value | Type |
| Switch | <BLOB> | 0 |
For making those skilled in the art be more fully understood that the present invention, describe the multimedia file storing process of the present invention in detail below by way of an object lesson:
The first step, pass on the interface of multimedia file on the client, picture that selected client to be uploaded is local or audio file;
Second step, server perform upload operation, selected picture or audio file are converted to binary stream file, and are deposited in table 2 and form corresponding data-base recording.
With reference to Fig. 2, it is shown that the flow chart of the read method embodiment of a kind of multimedia file of the present invention, specifically may comprise steps of:
Step 201, by client submit to multimedia file inquiry request;
Step 202, server, according to described inquiry request, retrieve the multimedia file record of correspondence in data base, and described multimedia file record are issued in the way of HTTP;
Step 203, client are according to the described corresponding multimedia file of HTTP information retrieval.
In implementing, described multimedia file record can include the information such as field name, field type and file type, then can include field name information in described inquiry request.
In one preferred embodiment of the present invention, it is also possible to comprise the following steps:
Step 204, client show described multimedia file.
For making those skilled in the art be more fully understood that the present invention, the multimedia file describing the present invention below by way of an object lesson in detail reads process:
The first step, client submit the inquiry request of multimedia file to;
Second step, service end-apparatus, according to querying condition, are retrieved corresponding record in data base, and these are existed the multimedia file in data base, issued to client by the mode of Http.
Be specifically as follows, dispose a Servlet (GetImageServlet) at server end, then the http address issued is:
Http: // 192.168.1.205:8080/nvmserver/GetImageServlet? resid=switch;
Wherein, 192.168.1.205 is the IP address of server end, and 8080 is port numbers, and resid is the Resid accessing picture or audio file, is specifically referred to the related content in table 1.
The above-mentioned http address of 3rd step, client-access, it is thus achieved that corresponding multimedia file, namely has access to the image of switch.
