In an embodiment according to the invention, the computing device 100 is configured to perform the resource access method 200 according to the invention. Wherein the operating system of the computing device 100 contains a plurality of program instructions for executing the resource access method 200 of the present invention, such that the resource access method 200 of the present invention can be executed in the operating system of the computing device 100.
According to one embodiment of the present invention, a resource access device 400 is disposed in an operating system of a computing apparatus 100, and the resource access device 400 includes a plurality of program instructions for executing the resource access method 200 of the present invention, so that the resource access method 200 of the present invention can be executed in the resource access device 400.
FIG. 2 illustrates a flow diagram of a resource access method 200 according to one embodiment of the invention. The resource access method 200 may be performed in an operating system of a computing device (e.g., the aforementioned computing device 100), and in particular may be performed in a resource access apparatus 400 in the operating system.
In an embodiment according to the invention, one or more applications are running on the operating system and at least one protocol analyzer, a plurality of protocol analyzers are arranged on the operating system.
In the specific embodiment, the present invention specifically describes the resource access method 200 by taking the Linux operating system as an example. However, it should be appreciated that the resource access method 200 of the present invention is not limited to a particular type of operating system that performs the method, and those skilled in the art will appreciate that the method can be implemented on other types of operating systems as well, such as Windows operating systems, without the need for inventive labor. Any kind of operating system that can achieve the speed of resource access based on URIs by the method of the invention is within the scope of the invention.
As shown in fig. 2, the method 200 begins at step S210.
In step S210, a request sent by an application program to access a resource based on a URI is received.
It should be noted that the present invention is not limited to a particular type of application. In one implementation, the application may be implemented as various types of file managers, such as Nautilus (the default file manager for the gnome desktop environment), dolphin (the default file manager for the KDE desktop environment), and the accessed resource may be various types of files, so that the method of the present invention may increase the speed of accessing the files. However, the present invention is not limited thereto.
Then, in step S220, the current optimal resolver information corresponding to the URI is acquired from the protocol analyzer based on the URI so as to resolve the URI based on the current optimal resolver. Here, the optimal parser is the highest priority protocol parser with the highest efficiency in URI parsing.
In one embodiment, the resource access device 400 requests the protocol analyzer to select the highest priority optimal resolver from the list of resolvers based on the URI. Specifically, the resource access device 400 may obtain a parser list from a configuration file and send the parser list to a protocol analyzer before receiving a request for accessing a resource based on a URI sent by an application. Here, the parser list includes a plurality of parsers matched with a plurality of resource protocols, wherein each resource protocol can adapt one or more parsers, and the plurality of parsers adapted for each resource protocol are preset with priority order. Thus, when the protocol analyzer selects the optimal analyzer for the first time, one or more resolvers matched with each resource protocol and a preset priority order of the resolvers can be determined according to the resolver list, and the resolver with the highest priority is selected from multiple resolvers according to the preset priority order of the resolvers to serve as the optimal analyzer.
The invention determines the priority order of the resolvers according to the resolution speed of the resolvers on the URI, wherein, for a plurality of resolvers matched with one resource protocol, the higher the resolution speed is, the shorter the access time is, the higher the priority of the resolvers is (the higher the priority order is); accordingly, the slower the parsing speed, the lower the priority of the parser (the later the priority order) the longer the access time.
It will be appreciated that the URI includes a corresponding resource protocol, and a parser matching the resource protocol in the URI can parse the URI. The optimal resolver is the highest priority protocol resolver, i.e., the first priority resolver, selected from one or more protocol resolvers matching the resource protocol in the URI.
It should be noted that when the resource protocol of the URI is adapted to multiple resolvers, the protocol analyzer selects the resolver with the highest priority from the multiple resolvers as the optimal resolver. If there is only one resolver that matches the resource protocol in the URI, the uniquely matching resolver can be directly taken as the optimal resolver.
In one embodiment, a protocol analyzer is provided with a parser query interface. In step S220, a parser query interface provided by the protocol analyzer may be invoked, and the current optimal parser information corresponding to the URI may be queried and obtained through the parser query interface.
Then in step S230, the corresponding current optimal resolver is pulled up based on the acquired current optimal resolver information, and the current optimal resolver is requested to resolve the URI to acquire the corresponding resource, the current optimal resolver may acquire the corresponding resource after resolving the URI, and then the resource information structure body is returned to the resource access device 400 as the resolving result, so that the resource access device 400 may acquire the resource information structure body returned by the current optimal resolver. Here, one or more kinds of resource attribute information (base information) are included in the resource information structure body.
Finally, in step S240, after acquiring the resource information structure returned by the current optimal resolver, the resource access device 400 sends the resource information structure to the protocol analyzer, and the protocol analyzer analyzes the resource information structure to determine the resource access type corresponding to the resource information structure and the next optimal resolver corresponding to the resource access type. Thus, when the resource that the application program requests to access based on the URI next time belongs to the resource access type, the next optimal parser information corresponding to the resource access type can be acquired from the protocol parser based on the URI.
In addition, after the resource information structure returned by the optimal resolver is obtained, the resource access device 400 returns the resource information structure to the application program, so that the application program obtains the result of accessing the resource based on the URI.
It should be noted that, the invention analyzes and selects the optimal analyzer through the protocol analyzer, and uses the optimal analyzer with the highest analysis speed to analyze the URI and acquire the resource, thereby improving the speed and the access efficiency of accessing the resource based on the URI.
FIG. 3 illustrates a timing diagram corresponding to resource access method 200 according to one embodiment of the invention. As shown in fig. 3, the application first pulls up the resource access device 400, and then the resource access device 400 pulls up the protocol analyzer, acquires the pull result returned by the protocol analyzer, and returns the pull result to the application. Next, the application initiates a URI request requesting the resource access device 400 to access the resource based on the URI. Subsequently, the resource access device 400 selects an optimal resolver type from the protocol analyzer based on the URI request, and acquires the optimal resolver type returned by the protocol analyzer. Next, the resource access device 400 pulls up the corresponding optimal resolver (the protocol resolver with the highest priority) according to the optimal resolver type, requests the optimal resolver to resolve the URI, and obtains the resolution result (resource information structure) returned by the optimal resolver. Subsequently, the resource access device 400 transmits the analysis result to the protocol analyzer to analyze the analysis result by the protocol analyzer, and the resource access device 400 returns the analysis result to the value application.
In one embodiment, the resource attribute information in the resource information structure includes, for example, one or more of the time consuming this access, the resource base type, the resource size, the resource depth (i.e., path depth), the number of sub-resources, and the list of sub-resources.
For example, the resource information structure may be implemented as:
in one embodiment, the protocol analyzer may analyze the resource information structure according to the following analysis method:
and determining the resource access type according to one or more resource attribute information in the resource information structure body, and acquiring the time-consuming data of the access from the resource information structure body. Here, the resource access type may be determined according to a range of attribute values in which one or more kinds of resource attribute information in the resource information structure body are located.
It should be noted that the present invention may define a plurality of resource access types based on different attribute value ranges of one or more kinds of resource attribute information in the resource information structure body. Specifically, resource information structures whose resource depths differ downward by no more than a resource depth threshold, whose resource sizes differ downward by no more than a resource size threshold, whose number of sub-resources differ downward by no more than a number of sub-resources threshold, and whose resource base types are the same may be defined as the same resource access type. Thus, when determining the resource access type based on one or more resource attribute information in the resource information structure, if the resource depth in the resource information structure differs downward by no more than a resource depth threshold, the resource size differs downward by no more than a resource size threshold, the number of sub-resources differs downward by no more than a number of sub-resources threshold, and the resource base types are the same, then the same resource access type may be determined.
In one implementation, the resource depth threshold is, for example, 1, the resource size threshold is, for example, 10%, and the sub-resource number threshold is, for example, 10%, that is, resource information structures whose resource depths differ downward by no more than 1, resource sizes differ downward by no more than 10%, sub-resource numbers differ downward by no more than 10%, and the resource base types are the same may be defined as the same resource access type. Conversely, exceeding the threshold may be defined as other resource access types.
And then, determining the next optimal resolver corresponding to the resource access type according to the historical access time-consuming data and the current access time-consuming data corresponding to the resource access type, so that the next optimal resolver with highest resolving efficiency and highest resolving speed is used for resolving the URI, the speed of accessing the resource based on the URI is improved, and the access time consumption is shortened as much as possible.
It should be noted that by defining multiple resource access types, the present invention can dynamically analyze the most efficient optimal resolver for each resource access type. Specifically, the invention classifies the resource accessed based on the URI, dynamically analyzes the optimal resolver with highest resolving efficiency and highest resolving speed according to the type of the resource access after the resource is acquired based on the URI each time, and can select the optimal resolver corresponding to the URI based on the result obtained by the latest analysis when the resource of the same type is accessed based on the URI later.
In one embodiment, whether to determine the current optimal resolver as the next optimal resolver corresponding to the resource access type is determined based on whether the time consuming data of the current access exceeds a time consuming threshold. Specifically, whether the time-consuming data of the current access exceeds a time-consuming threshold is judged, and if the time-consuming data of the current access does not exceed the time-consuming threshold, the optimal resolver of the current time is determined to be the optimal resolver of the next time corresponding to the resource access type. In one implementation, the time consumption threshold is, for example, 1000ms, but the present invention is not limited to a specific value of the time consumption threshold, which can be set by one skilled in the art according to actual needs.
If the time-consuming data of the current access exceeds the time-consuming threshold, judging whether the resource access type is the first access, and if the resource access type is the first access (no time-consuming data of the historical access exists), determining the second priority resolver as the next optimal resolver corresponding to the resource access type based on the priority order of the preset resolvers. That is, the order of the first priority resolver and the second priority resolver in the preset resolver priority order is adjusted, and the original second priority resolver is set as the highest priority resolver of the next (the next optimal resolver).
In addition, if the time-consuming data of the current access exceeds the time-consuming threshold, and the resource access type is not the first access (there is historical time-consuming data of the access), the priority order of the resolvers can be dynamically adjusted according to the historical time-consuming data of the access corresponding to the resource access type and the time-consuming data of the current access, wherein the priority order of the resolvers with shorter access time consumption is higher as the priority order is higher, and finally the next optimal resolvers corresponding to the resource access type can be determined.
In one embodiment, the protocol analyzer may determine a next best resolver corresponding to a resource access type through intelligent learning. The specific learning method is as follows: the protocol analyzer selects the optimal analyzer several times (configurable times) by executing the above analysis method, and a stable analyzer A is obtained after the analyzer selects to be stable. Then the rule of selecting the optimal resolver is reset, and the optimal resolver is selected for a plurality of times (the configurable times) to obtain the resolver B which is stabilized again. If resolver A is equal to resolver B, then it may be determined to be the next best resolver corresponding to the resource access type. If the resolver A is not equal to the resolver B, the learning method can be repeatedly executed to obtain the two stabilized resolvers until the two stabilized resolvers are the same, and the next optimal resolver corresponding to the resource access type can be determined.
Further, the definition of the resource access type can be further refined, and the learning method can be executed to determine the next optimal resolver corresponding to the refined resource access type. For example, the resource depth threshold is changed to be the same, the resource size threshold is changed to 5%, the sub-resource number threshold is changed to 5%, and the time-consuming threshold is changed to 500ms, and a better solution is obtained by executing the above learning method.
Fig. 4 shows a schematic diagram of a resource access device 400 according to an embodiment of the invention. The resource access device 400 is deployed in an operating system of a computing apparatus (e.g., the aforementioned computing apparatus 100) and is adapted to perform the resource access method 200 of the present invention. Wherein one or more applications are running on the operating system, and at least one protocol analyzer, a plurality of protocol analyzers are disposed on the operating system.
As shown in fig. 4, the resource access device 400 includes a receiving unit 410, an acquiring unit 420, an analyzing unit 430, and an analyzing unit 440, which are sequentially connected. Wherein the receiving unit 410 may receive a request for accessing a resource based on a URI sent by an application. The obtaining unit 420 obtains the information of the current optimal resolver from the protocol analyzer based on the URI, where the optimal resolver is the resolver with the highest resolving efficiency. The parsing unit 430 requests the current optimal parser to parse the URI based on the current optimal parser information, so as to obtain a resource information structure body returned by the current optimal parser. The analysis unit 440 transmits the resource information structure to the protocol analyzer, and analyzes the resource information structure by the protocol analyzer to determine a resource access type corresponding to the resource information structure and a next optimal analyzer corresponding to the resource access type.
It should be noted that the receiving unit 410 is configured to perform the foregoing step S210, the acquiring unit 420 is configured to perform the foregoing step S220, the analyzing unit 430 is configured to perform the foregoing step S230, and the analyzing unit 440 is configured to perform the foregoing step S240. Here, the specific execution logic of the receiving unit 410, the obtaining unit 420, the analyzing unit 430, and the analyzing unit 440 refers to the descriptions of steps S210 to S240 in the foregoing method 200, and will not be repeated here.
According to the resource access method 200 of the present invention, the optimal resolver with highest resolution efficiency and highest resolution speed can be selected based on different URIs to resolve the URIs. After the resource information structure body returned by the optimal analyzer is obtained each time, not only the resource information structure body is returned to the application program, but also further learning and analysis are performed by sending the resource information structure body to the protocol analyzer, so as to determine the resource access type and analyze the resource access type to obtain the next optimal analyzer corresponding to the resource access type. In this way, the invention dynamically analyzes the optimal analyzer with highest analysis efficiency and highest analysis speed based on each resource access type, the analyzed optimal analyzer is dynamically performed and updated, and when the application program accesses the same type of resource based on the URI next time, the next optimal analyzer information corresponding to the URI obtained by the latest analysis can be obtained from the protocol analyzer. According to the technical scheme of the invention, the URI is analyzed and the resource is acquired by using the optimal analyzer with the highest dynamic analysis speed, so that the resource accessing speed of an application program based on the URI can be improved, the accessing efficiency is improved, and the time consumption of accessing is shortened as much as possible.
