Description
Technical field
The present invention relates to order line analytic technique fields, and in particular to a kind of realization method and system of order line input.
Background technology
The existing all kinds of products for data communication, such as interchanger, router, fire wall, modem, PON (Passive
Optical Network, passive optical-fiber network), GTN (General Transport Network, general transmission net), PTN
(Packet Transport Network, Packet Transport Network) etc., can all provide a kind of management means being called order line, i.e.,
User inputs specific order line (showing as a string of character strings), is parsed by the order line kernel analysis program in equipment,
Know that the operation of user is intended to, then executes and feedback result is to user.As soon as simply example, such as windows operations
Ping orders in system are exactly a kind of order line.Industry Normal practice is exactly by all order line prototypes with the shape of command tree
Formula is stored.After order line kernel analysis program receives user's input, tree root just is traversed from the tree crown of command tree, is searched
Order line is inputted with user and matches order line prototype, and after finding matched order line prototype, it is corresponding to be carried out this order line
Execute function.
As shown in Figure 1, being the schematic diagram of command tree, command tree stores command-line string with tree structure
A kind of data structure.Each bifurcated of command tree, is exactly order line node, and order line prototype is hung under each node.
It is character string that user, which inputs order line, and order line kernel analysis program is exactly to be matched according to character string, to feel
Know user view.Parameter in order line input by user is all materialization, and the ginseng for the order line registered on command tree
Number is all that Scoped is considered as long as design parameter input by user belongs to the legal range of command line parameter on command tree
Be them it is matched.But this matching rule is more stiff, must strictly observe succession and integrality.
By taking ping orders as an example：
Table 1
Table 1 is order line prototype and user's input order line matching list on command tree.By taking serial number 2 as an example, user's input
When, after having inputted the addresses keyword ping and ip, it must just force first to input keyword-w, then could input keyword-
S, and this 2 keywords and parameter must have all been inputted, it is only valid operation, it could 2 order line prototype of successful match serial number.
If user merely desires to input-w, actual match be serial number 1 on command tree order line prototype rather than serial number 2.Or
First input-s, then input-w, then actual match be serial number 3 on command tree order line prototype.If user has input
Ping 1.1.1.1-s20-w10 add parameter that is, behind keyword, and do not have the order line prototype ping of serial number 3 on command tree
(A.B.C.D)–s<1-100>–w<1-200>, then order line kernel analysis program can not be matched to order line prototype, will judge
User's input is illegal, leads to not execute this order line.This is exactly that conventional order line kernel analysis program is strictly required
Succession and integrality.
But some order lines are other than the keyword and parameter that must input, also possess many optional keywords and
Parameter, user are inputting these optional keywords and when parameter, the combination of optional keyword and parameter is arbitrary, it is random can
Speech, this results in this order line, and there are many kinds of combining forms.By taking ping orders as an example：
C:\Users\ytao>ping/
Usage:ping[-t][-a][-n count][-l size][-f][-i TTL][-v TOS]
[-r count][-s count][[-j host-list]|[-k host-list]]
[-w timeout][-R][-S srcaddr][-4][-6]target_name
Option:
Host specified-t Ping, until stopping.
Control-Break please be key in check statistical information and continuing operation-；To that stop-please keying in
Control-C。
- a is by address resolution at host name.
- n count echo the number of requests to be sent.
- l size send buffer size.
" not being segmented " mark (being only applicable to IPv4) is arranged in-f in the packet.
- i TTL life spans.
- v TOS service types (are only applicable to IPv4.The setting is not agreed with using, and in IP headers
Type of service field there is no any influence).
The routing (being only applicable to IPv4) of-r count record count hops.
- s count count the timestamp (being only applicable to IPv4) of hop.
Loose source routings (the be only applicable to IPv4) of-j host-list together with Host List.
Stringent source routings (the be only applicable to IPv4) of-k host-list together with Host List.
- w timeout wait for the time-out time (millisecond) replied every time.
- R is equally using routing header test reverse route (being only applicable to IPv6).
- S srcaddr source addresses to be used.
- 4 force to use IPv4.
- 6 force to use IPv6.
Ping orders further include 16 optional keywords other than target_name is must to specify.And these can
The band parameter (such as-n/-l/-i) that keyword has is selected, for some without parameter (such as-t/-a/-f), this results in the order line of ping
Prototype has very multiple combinations form.These combining form numbers are too many, and exhaustive all combinations are obviously unrealistic, and work
It measures huge, all brings certain difficulty for registration and the realization in later stage, and can not extend.
Invention content
In view of the deficiencies in the prior art, the purpose of the present invention is to provide a kind of implementation methods of order line input
And system, it supports the random combine input of optional keyword and parameter, does not have to the number for considering optional keyword and parameter and suitable
Sequence problem is registered and is realized convenient for order line, is reduced workload, can subsequently be extended.
To achieve the above objectives, the present invention takes a kind of implementation method of order line input, including step：
Defining optional keyword and parameter in custom command row and being placed on must input below, and use character string generation
It replaces；
Define the self-defined analytical function of an analysis definition command row, and be registered on command tree described in from
Definition command row is bound；
Judge whether the optional keyword and parameter are legal by the self-defined analytical function, meanwhile, according to order
Custom command row prototype is automatically replenished the optional keyword of part input on tree.
Based on the above technical solution, the order line of the self-defined analytical function parsing input, traverses command tree,
It searches and passes through self-defined analytical function if the order line prototype is customized with the matched order line prototype of the order line
It is parsed；If the order line prototype is not customized, parsed by original flow.
Based on the above technical solution, defining the custom command row includes：
To custom command row support in need optional keyword definition enumerate；
A data structure is defined, by each optional keyword, corresponding help information and corresponding parameter area information
It is associated between three；
An array is defined, member is the data structure；
Define the form of the custom command row, it is necessary to which the keyword and parameter of input are placed on front, all optional passes
Key word and parameter are put behind.
Based on the above technical solution, in the data structure, if optional keyword is without parameter, corresponding ginseng
Number range information is sky.
Based on the above technical solution, the self-defined analytical function parses custom command row, if current input
Optional keyword and array in the optional keyword that stores mismatch, or the optional keyword currently inputted and inputted
There are logic conflicts for optional keyword, think that input is illegal, terminate flow.
Based on the above technical solution, the self-defined analytical function parses custom command row, if current input
Optional keyword do not patrolled with the optional keyword for matching, currently inputting stored in array and the optional keyword inputted
Conflict is collected, and the parameter that user continues to input belongs to corresponding parameter area in array, then illustrates the optional key currently inputted
Word and corresponding parameter are legal.
Based on the above technical solution, the self-defined analytical function parses custom command row, if current input
Optional keyword it is as some the optional keyword part stored in array identical, match, then directly according to being stored in array
Optional keyword is supplemented, and is extracted the optional keyword and substituted the character string used when corresponding optional keyword registration,
Obtain the corresponding help information of the optional keyword and corresponding parameter area.
Based on the above technical solution, self-defined analytical function parses custom command row, if what is currently inputted can
It selects keyword identical as at least two optional keywords all parts stored in array, matches, then it is identical to provide all parts
Optional keyword is selective, substitutes the character string used when corresponding optional keyword registration with selected optional keyword, obtains
To the corresponding help information of the optional keyword and corresponding parameter area.
Based on the above technical solution, if the optional keyword has corresponding parameter area, and do not have subsequently
Input parameter, or the parameter subsequently inputted are not belonging to corresponding parameter area in comparison array, then critical parameter is illegal
State, flow terminate.
The present invention also provides a kind of realization systems of order line input, including：
Order line definition module is used for behind optional keyword and parameter in definition command row be placed on and must input,
And it is replaced using character string；
Parsing module is used to be automatically replenished the optional key of part input according to chartered custom command row
Word is additionally operable to judge whether the optional keyword of input and parameter are legal.
Based on the above technical solution, the order line definition module includes data structure and array, data structure
It will be associated between each optional keyword, corresponding help information and corresponding parameter area information three；Array at
Member is the data structure.
Based on the above technical solution, the parsing module includes：
Custom command row discrimination module, is used to traverse command tree, judges whether the order line of input is registered
Custom command row；
Keyword discrimination module is used to traverse the legitimacy that the array judges the optional keyword currently inputted；
Parameter discrimination module is used to traverse the array and judges the optional keyword subsequent input parameter currently inputted
Legitimacy.
Based on the above technical solution, the keyword discrimination module further includes association's unit, is used for part
The legal optional keyword of input is supplemented, and obtains the corresponding help information of the optional keyword and corresponding parameter model
It encloses.
Based on the above technical solution, if some the optional pass stored in the optional keyword and array that currently input
Key character segment is identical, matches, and association's unit is directly optional to what is currently inputted according to the optional keyword stored in array
Keyword is supplemented.
Based on the above technical solution, if stored in the optional keyword and array that currently input at least two can
It selects keyword all parts identical, matches, the identical optional keyword in all parts of association's unit offer is selective, with quilt
The keyword of selection substitutes the character string used when corresponding optional keyword registration.
The beneficial effects of the present invention are：
1, custom command row is defined, all optional keywords and its parameter are replaced with the character string PS of no practical significance
In generation, without exhaustive all combinations when registration, greatly reduces life without paying close attention to the sequence and permutation and combination problem of optional keyword
Enable the number-of-registration of row.When user inputs, according to user input values, it can associate automatically and match corresponding optional pass in array
Key word or parameter are replaced the character string in order line, are realized simply, securely and reliably in turn.Custom command row includes
Optional keyword is more, and the benefit of inventive method is more apparent, and advantage is bigger.
2, extremely small to the change of original order line kernel analysis program, when custom command row is registered, it is only necessary to tie up
Fixed self-defined analytical function can reduce workload for non-custom order line without binding.Even if self-defined
Self-defined analytical function realize wrong, also only influence this current order line, other order lines will not be parsed and be caused
Any influence.
3, existing order line kernel analysis program, its own is actively to include and judge each order line keyword
Between logical relation too complicated because information content is too big, processing logic cannot be realized.But the present invention is for self-defined
Logical relation between order line optional keyword judges, can be placed in self-defined analytical function and realize, to realize
Judge user's input logic legitimacy.When the logical relation between all kinds of optional keywords of custom command row changes,
Self-defined analytical function only need to be changed and kernel analysis program is unrelated, it is convenient, fast, efficient.
