Abstract
The invention discloses a kind of file access methods, comprise the following steps, S1: passing through the network address character recognition local file or network file of specific format；S2: if network file, S3 is thened follow the steps；If local file, then S4 is executed；S3: utilizing window application page file address, Windows function address is mapped to local function address, network file is then transferred to the corresponding service routine processing of network, executes step S5；S4: local file is distributed to Windows API, executes step S5；S5: terminate.The solution of the present invention supports the operation of a variety of files, so that local file is consistent with network file browsing process, user can equally operate network file as local file, without any application layer transport protocol, it is high-efficient, it is at low cost, improve the quick access in video portrait identification Compare System to video image, and system is supported to carry out networking extension, conducive to sharing out the work and help one another in qualification process is improved.
Description
Technical field
The present invention relates to network file process field more particularly to a kind of file access methods.
Background technique
How local file system and network file are accessed simultaneously, is the emphasis of many people's researchs.But it if can be efficiently
Access network file and local file, be the problem that many technical staff explore always.
For this purpose, derivative problem focuses primarily upon: if realizing local folders visiting from outside, and having ignored will be outer
Portion's network file realizes the access mode for being similar to local file.
To solve the above-mentioned problems, the present invention proposes a kind of file access method.
Summary of the invention
To solve the above-mentioned problems, the present invention proposes that a kind of file access method, the document method comprise the following steps,
S1: pass through the network address character recognition local file or network file of specific format；
S2: if network file, S3 is thened follow the steps；If local file, then S4 is executed；
S3: window application page file address is utilized, Windows function address is mapped to local function address, network
File is then transferred to the corresponding service routine processing of network, executes step S5；
S4: local file is distributed to Windows API, executes step S5；
S5: terminate.
In step S3 and step S4, first monitoring network environment is needed, and network parameter is arranged according to network environment.
The network environment includes network bandwidth, and the network parameter includes the file packet threshold size of file transmission.
The network bandwidth is positively correlated with the file packet threshold size.
If the network adaptability that the network environment is embodied is bad, by data buffer storage, rewriting data is improved into
Power.
It in data transmission procedure, also monitors comprising data transmission failure, if transmission fault occurs, is reset using file
Position is fault-tolerant to carry out.
The specific file format is<ServerPath>[Ipaddress@port]<FilenameExtension
>。
The beneficial effects of the present invention are: (reading and writing, attribute are obtained, position, create, are deleted for 1. operations for supporting a variety of files
Except etc.).2. local file is consistent with network file browsing process, user can equally grasp network file as local file
Make, is not necessarily to any application layer transport protocol, it is high-efficient, it is at low cost.Compare System is identified in video portrait 3. being greatly improved
In quick access to video image, and system is supported to carry out networking extension, conducive to sharing out the work and help one another in qualification process is improved.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；Fig. 2 is the structural schematic diagram of the preferred embodiment of the present invention.
Specific embodiment
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control attached drawing 1-2 illustrates this
The specific embodiment of invention.
The present invention proposes that a kind of file access method, the document method comprise the following steps,
S1: pass through the network address character recognition local file or network file of specific format；
S2: if network file, S3 is thened follow the steps；If local file, then S4 is executed；
S3: window application page file address is utilized, Windows function address is mapped to local function address, network
File is then transferred to the corresponding service routine processing of network, executes step S5；
S4: local file is distributed to Windows API, executes step S5；
S5: terminate.
In step S3 and step S4, first monitoring network environment is needed, and network parameter is arranged according to network environment.
The network environment includes network bandwidth, and the network parameter includes the file packet threshold size of file transmission.
The network bandwidth is positively correlated with the file packet threshold size.
Preferably, the network bandwidth is positively correlated in certain phase with file packet threshold size, when it is more than certain rank
Duan Hou, file packet threshold size no longer change.
If the network adaptability that the network environment is embodied is bad, by data buffer storage, rewriting data is improved into
Power.
It in data transmission procedure, also monitors comprising data transmission failure, if transmission fault occurs, is reset using file
Position is fault-tolerant to carry out.
The specific file format is<ServerPath>[Ipaddress@port]<FilenameExtension
>。
For example, C: Users cxj Desktop DS-2ZCN3007_720P_25fps_2M [10.6.30.120@
7156] .smf can be used as one kind of format.
It should be noted that for simple description, therefore, it is stated as a systems for each embodiment of the method above-mentioned
The combination of actions of column, but those skilled in the art should understand that, the application is not limited by the described action sequence, because
For according to the application, certain some step be can be performed in other orders or simultaneously.Secondly, those skilled in the art also should
Know, the embodiments described in the specification are all preferred embodiments, related movement and unit not necessarily this Shen
It please be necessary.
In the above-described embodiments, it all emphasizes particularly on different fields to the description of each embodiment, is not described in some embodiment
Part, reference can be made to the related descriptions of other embodiments.
Those of ordinary skill in the art will appreciate that realizing all or part of the process in above-described embodiment method, being can be with
Relevant hardware is instructed to complete by computer program, the program can be stored in computer-readable storage medium
In, the program is when being executed, it may include such as the process of the embodiment of above-mentioned each method.Wherein, the storage medium can be magnetic
Dish, CD, ROM, RAM etc..
The above disclosure is only the preferred embodiments of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, therefore equivalent changes made in accordance with the claims of the present invention, is still within the scope of the present invention.
