Description
Technical field
The present invention relates to internet arena, be specifically related to a kind of URL reorientation method, Apparatus and system.
Background technology
URL (Uniform Resource Locator, URL(uniform resource locator)) is the resource address of standard on internet, for intactly describing webpage and other resources on internet.URL is comprised of a series of characters, and form is protocol: // [username:password] host[/path] [? query].Wherein, protocol territory given transmission agreement; Username and password territory are specified and are connected to the required username and password of server; Host name or the IP address of the server of depositing resource specified in host territory; The store path of resource in the given host of path territory; Query territory is assigned to the parameter that dynamic web page transmits.During the information resources of client-requested access services device, need agreement, the server of request, the information such as the store path of request resource (being referred to as request path in the present invention) of determining that request is used, above-mentioned information is all provided by URL address.
URL is redirected and is called again URL rewriting (URL Rewrite), refers to the URL address that server intercepting is imported into, this URL address is redirected to the process of other URL.The URL address sending such as browser is www.autohome.com.cn/364/, the configuration file that server is redirected according to URL, automatically www.autohome.com.cn/XXX.aspx is redirected to in this URL address? id=364, the URL address that client is seen while still sending request, but actual access is the URL address (the resource store path in this URL address, is referred to as to apply path in the present invention) after being redirected.The redirected advantage of URL is: shorten the length of URL address, hide Actual path and improve fail safe; Be easy to user's memory and key in; Being easy to searched engine includes; Be convenient to network upgrade.
The redirected implementation of existing URL is, first obtains the redirected configuration file of URL, for example, be:
Above-mentioned configuration file is xml file, this xml file comprises that many are redirected rule (for regular expression rule), every redirected rule is expressed by <RewriterRule> element, each <RewriterRule> element comprises <LookFor> element and <SendTo> element, the pattern that will search in requested URL is by <LookFor> element representation, replace the character string of found pattern by <SendTo> element representation.
Then, server intercepts file request for example during aaa.xml, in configuration file, find from the top down the redirected rule of coupling, adopt regular expression (regular expression) coupling, result has matched above-mentioned redirected rule, therefore aaa.xml an is redirected to/aaa/bbb.aspx.
Regular expression refers to one " character string " describes a feature, to verify whether another " character string " meets this feature.For example expression formula " mn* " is described the feature of a character string, and this feature is comprised of one " m " and arbitrarily individual " n ", if character string to be verified is " mn ", " mnn " or " mnnnnnn ", these character strings all meet this feature.
But, adopt the speed of matching regular expressions slower, and the system resource consuming is also higher.Particularly for complicated website, its redirected rule for the redirected configuration file of URL is a lot, adopt the mode of matching regular expressions to carry out URL and be redirected and can make the speed of client-access server resource slower, make user's experience effect not good.

Embodiment
Exemplary embodiment of the present disclosure is described below with reference to accompanying drawings in more detail.Although shown exemplary embodiment of the present disclosure in accompanying drawing, yet should be appreciated that and can realize the disclosure and the embodiment that should do not set forth limits here with various forms.On the contrary, it is in order more thoroughly to understand the disclosure that these embodiment are provided, and can by the scope of the present disclosure complete convey to those skilled in the art.
Fig. 1 shows the structure chart of URL Redirectional system according to an embodiment of the invention.As shown in Figure 1, URL Redirectional system comprises a plurality of clients 110 (there is shown 3), for these clients 110 provide the server end 120 of various network resources, and client 110 and server end 120 be intercommunication mutually via internet.
In embodiments of the present invention, client 110 can be any equipment that can present the Internet resources that obtain from server end 120 in this area, includes but not limited to desktop computer, notebook computer, personal digital assistant, intelligent mobile terminal and panel computer etc.Client 110 has operating system, and in operating system, operation has browser, and described browser can present the Internet resources that obtain from server end 120, for example web page files.
Server end 120 is answered the request (for example http request) of client 110 and asked Internet resources is returned to client 110.During the Internet resources of client 110 request access server ends 120, need agreement, the server of request, the information such as the store path of request resource (being referred to as request path in the present invention) of determining that request is used, above-mentioned information is all provided by URL address.For example, the request URL of client 110 is http://www.autohome.com.cn/aaa/20/article.html, and the request path in this URL is /aaa/20/article.html, and the first class catalogue of this request path is /aaa.
In some cases, the URL that server end 120 need to be asked client 110 is redirected, the request path being about in URL is rewritten as other paths (being referred to as to apply path in the present invention) in server end 120, therefore, server end 120 also comprises URL redirection device 200, by URL redirection device 200, carries out being redirected of URL.For example, does is URL redirection device 200 redirected above-mentioned URL into http://www.autohome.com.cn/ccc.aspx? does is does is id=20, about to request path/aaa/20/article.html and redirected to application path/ccc.aspx? id=20.After URL is redirected, does is the URL of client 110 actual access http://www.autohome.com.cn/ccc.aspx? id=20, client 110 sees that URL's remains http://www.autohome.com.cn/aaa/20/article.html, like this, just shorten the length of the URL address of user's input, thereby hidden the fail safe that Actual path has improved Internet resources.
Fig. 2 shows the structure chart of URL redirection device 200 according to an embodiment of the invention.Described URL is heavy to be arranged in server end 120 to device 200, and the URL that is suitable for client 110 to ask is redirected.
With reference to Fig. 2, described URL redirection device 200 comprises data dictionary generation unit 210, first class catalogue acquiring unit 220, dictionary lookup unit 230 and redirected unit 240.
Data dictionary generation unit 210 is suitable for the configuration file generated data dictionary redirected according to URL.The data dictionary generating comprises one or more data entries, redirected rule (for the rule based on the regular expression) set that each data entry comprises directory name and is associated with this directory name, described directory name is the first class catalogue of request path in the redirected rule of configuration file, the redirected regular collection being associated with this directory name is the set in configuration file with the redirected rule that the request path of this first class catalogue is corresponding, the subset that this set is the included all redirected rules of configuration file.That is to say, data dictionary generation unit 210 is sorted out the redirected rule in configuration file according to the first class catalogue of request path, redirected rule corresponding to request path that first class catalogue is identical is classified as a class, and is stored as a data entry of data dictionary.
Server end 120 for example stores for carrying out the redirected configuration file of URL in Website server, and described configuration file comprises that some are redirected rule, and described redirected rule is the redirected rule based on regular expression.This configuration file stores in Website server after for example can being set by website design personnel.
For example, in server end 120, the configuration file of storage is as follows:
Above-mentioned configuration file is xml file, this xml file comprises that 4 are redirected rule (for regular expression rule), every redirected rule is expressed by <RewriterRule> element, each <RewriterRule> element comprises <LookFor> element and <SendTo> element, the pattern that will search in requested URL is by <LookFor> element representation, replace the character string of found pattern by <SendTo> element representation.
For example, in above-mentioned configuration file, article one, the pattern that is redirected in regular <LookFor> element "～/aaa/ (d+)/" and indicates to search is: the first class catalogue of URL request path is /aaa/, second-level directory is/(d+), and wherein " d+ " represents one or more numerals; Article one be redirected in regular <SendTo> element "～/bbb.aspx? id=$ 1 " represent when URL request path mates with "～/aaa/ (d+)/", by the request path of this URL kind replace with application path "/bbb.aspx? id=$ 1 ", wherein $ 1 represents in "～/aaa/ (d+)/" value of regular expression in first bracket.
Data dictionary generation unit 210 can carry out the configuration file generated data dictionary redirected according to URL in the following manner: from configuration file, read one by one and be redirected rule; For every that reads redirected rule, this is redirected to the first class catalogue and adding in data dictionary that this redirected rule is associated of regular request path.Particularly, be redirected rule for every that reads, first judge whether this first class catalogue that is redirected regular request path is present in data dictionary (judge in data dictionary whether exist the data entry corresponding with this request path); Then, when this first class catalogue is not present in data dictionary, this first class catalogue and this redirected regular incidence relation are added in data dictionary as a data entry; When this first class catalogue is present in data dictionary, this redirected rule is added in the redirected regular collection being associated with this first class catalogue in data dictionary and (upgrade data entry corresponding with this first class catalogue in data dictionary, this redirected rule is added in the included redirected regular collection of this data entry).
In addition, the request path of the redirected rule in described configuration file may be the first class catalogue set of a plurality of first class catalogues formations.For example, for the last item in above-mentioned configuration file, be redirected in regular <LookFor> element, the first of request path/(a1|a2|a3) is the set that 3 first class catalogues form, be respectively/a1 ,/a2 and/a3.In such cases, data dictionary generation unit 210 is respectively by each first class catalogue in first class catalogue set and adding in data dictionary that this redirected rule is associated, for above-mentioned example, in data dictionary, add 3 data entries, be respectively/a1 of the directory name of these three data entries ,/a2 and/a3, the redirected rule being associated is:
<LookFor>～/(a1|a2|a3)/\ad{6}/(\d+)12\.html</LookFor>
<SendTo>～/mmm/ddd.aspx？id＝$2</SendTo>
In addition, the first class catalogue of the request path of the redirected rule in described configuration file may be also numerical character string variable, for example, be/(d+), in such cases, in data dictionary, data strip destination directory name is called this numerical character string variable.
Data entry in data dictionary specifically can be stored mode with key-value (key-value).For example, key corresponding to data dictionary generating according to above-mentioned configuration file is respectively: aaa, ddd, a1, a2, a3, and the value that aaa is corresponding comprises that two are redirected rule, are respectively:
The value that ddd is corresponding comprises that is redirected a rule, as follows:
A1, a2, the value that a3 is corresponding are identical, comprise that is redirected a rule, as follows:
First class catalogue acquiring unit 220 is suitable for obtaining the URL of client 110 requests, obtains the first class catalogue of request path from this URL.When client 110 needs the Internet resources in access services device end 120, send request (for example http request) to server end 120, this request comprises the URL that these Internet resources are corresponding, first class catalogue acquiring unit 220 can obtain the request path in this URL, and obtains the first class catalogue in this request path.
For example, the request path in the URL of client 110 requests is /mmm/20/ that corresponding first class catalogue is mmm; Again for example, the request path in the URL of client 110 requests is /aaa/20/article.html that corresponding first class catalogue is aaa.
The first class catalogue that dictionary lookup unit 230 is suitable for obtaining according to first class catalogue acquiring unit 220 is searched the redirected regular collection being associated from data dictionary.For example, when the first class catalogue getting is mmm, according to mmm, search data dictionary, in data dictionary, not having directory name is the data entry of mmm, searches unsuccessfully; Again for example, when the first class catalogue getting is aaa, according to aaa, search data dictionary, in data dictionary, having directory name is the data entry of aaa, and in this data entry, the redirected regular collection associated with aaa comprises that two are redirected rule, as follows:
In addition, when accessed first class catalogue is digit strings, this digit strings is directly mated with the numerical character string variable in data dictionary.
Redirected unit 240 is suitable for that the request path in the URL of request is carried out to canonical with the redirected regular collection finding and mates (matching regular expressions), and according to the redirected rule matching, URL is redirected.Being redirected unit 240 can take out and be redirected rule one by one from the redirected regular collection finding, and the redirected rule of this request path and this is carried out to canonical and mate; When matching certain redirected rule, this request path is redirected to the application path in matched redirected rule; When all redirected rules are not all mated, this URL is not redirected.
Certainly, if when the first class catalogue that dictionary lookup unit 230 obtains according to first class catalogue acquiring unit 220 is searched data dictionary, if searched unsuccessfully, be redirected unit 240 and also this URL be not redirected.
For example, the request path in the URL of client 110 request is /mmm/20/, according to first class catalogue mmm, searches unsuccessfully, this URL is not redirected.
Again for example, the request path in the URL of client 110 request be/aaa/20/article.html, and above-mentioned two the redirected rules that find according to first class catalogue aaa are carried out matching regular expressions, and result matches second and is redirected regular:
So, according to this second, be redirected rule, the request path/aaa/20/article.html in the URL of request redirected to application path/ccc.aspx? id=20.
According to the URL redirection device of the embodiment of the present invention, in advance the redirected rule in configuration file is sorted out according to the first class catalogue of request path, and adopt data dictionary to preserve, carrying out URL while being redirected, first by data dictionary, search first class catalogue, found and carried out again matching regular expressions, otherwise do not carry out matching regular expressions, avoided directly carrying out the situation of matching regular expressions failure, thereby improved the efficiency of match hit, and then improved the speed of resource in the redirected processing speed of URL and client-access server.And what carry out matching regular expressions is only a subset of all redirected rules, has further improved the redirected processing speed of URL.
For example, for above-mentioned, comprise that request path is /URL of mmm/20/, according to existing URL redirection scheme, even if do not exist in configuration file and/redirected rule that mmm/20/ is corresponding, also need all redirected rule in configuration file to carry out successively matching regular expressions processing procedure, waste a large amount of server process resources, and caused the speed of Internet resources in client-access server also slower; And according to the URL redirection scheme of the embodiment of the present invention, when searching less than the canonical table expression formula set corresponding with first class catalogue mmm according to data dictionary, do not proceed the coupling of regular expression, directly determine this URL not to be redirected, significantly improved the redirected processing speed of URL.
It should be noted that, above-mentioned data dictionary generation unit 210 is selectable unit, be can not comprise described data dictionary generation unit 210 in described URL redirection device 200, data dictionary is input to server end 120 after can be pre-configured, by URL redirection device 200, is used.
Fig. 3 shows the flow chart of URL reorientation method according to an embodiment of the invention, and this URL reorientation method is carried out by server end.
With reference to Fig. 3, this URL reorientation method starts from step S302.In step S302, the configuration file generated data dictionary redirected according to URL.The data dictionary generating comprises one or more data entries, redirected rule (for the rule based on the regular expression) set that each data entry comprises directory name and is associated with this directory name, described directory name is the first class catalogue of request path in the redirected rule of configuration file, the redirected regular collection being associated with this directory name is the set in configuration file with the redirected rule that the request path of this first class catalogue is corresponding, the subset that this set is the included all redirected rules of configuration file.That is to say, be that the redirected rule in configuration file is sorted out according to the first class catalogue of request path, and redirected rule corresponding to request path that first class catalogue is identical is classified as a class, and be stored as a data entry of data dictionary.
In step S302, can carry out in the following manner the configuration file generated data dictionary redirected according to URL: from configuration file, read one by one and be redirected rule; For every that reads redirected rule, this is redirected to the first class catalogue and adding in data dictionary that this redirected rule is associated of regular request path.Particularly, be redirected rule for every that reads, first judge whether this first class catalogue that is redirected regular request path is present in data dictionary (judge in data dictionary whether exist the data entry corresponding with this request path); Then, when this first class catalogue is not present in data dictionary, this first class catalogue and this redirected regular incidence relation are added in data dictionary as a data entry; When this first class catalogue is present in data dictionary, this redirected rule is added in the redirected regular collection being associated with this first class catalogue in data dictionary and (upgrade data entry corresponding with this first class catalogue in data dictionary, this redirected rule is added in the included redirected regular collection of this data entry).
In addition, the request path of the redirected rule in described configuration file may be the first class catalogue set of a plurality of first class catalogues formations.In such cases, be respectively by each first class catalogue in first class catalogue set and adding in data dictionary that this redirected rule is associated.In addition, the first class catalogue of the request path of the redirected rule in described configuration file may be also numerical variable variable, for example, be/(d+), in such cases, in data dictionary, data strip destination directory name is called this numerical variable variable.Wherein, the data entry in data dictionary specifically can be stored mode with key-value (key-value).
It should be noted that, in step S302 the performed processing processing performed with data dictionary generation unit 210 identical, specifically can, with reference to the description to data dictionary creation unit 210 above, not repeat here.
After having generated data dictionary in advance by step S302, method enters step S304.In step S304, obtain the URL of client-requested, from this URL, obtain the first class catalogue of request path.It should be noted that, in step S304 the performed processing processing performed with first class catalogue acquiring unit 220 identical, specifically can, with reference to the description to first class catalogue acquiring unit 220 above, not repeat here.
After getting the first class catalogue of request path, method enters step S306.In step S306, according to the first class catalogue obtaining, from data dictionary, search the redirected regular collection being associated.
It should be noted that, in step S306 the performed processing processing performed with dictionary lookup unit 230 identical, specifically can, with reference to the description to dictionary lookup unit 230 above, not repeat here.
After finding the redirected regular collection being associated, method enters step S308.In step S308, the request path in the URL of request is carried out to canonical with the redirected regular collection finding and mate, and according to the redirected rule matching, URL is redirected.Can from the redirected regular collection finding, take out and be redirected rule one by one, the redirected rule of this request path and this be carried out to canonical and mate; When matching certain redirected rule, this request path is redirected to the application path in matched redirected rule; When all redirected rules are not all mated, this URL is not redirected.Certainly, if while searching unsuccessfully in step S304, this URL is not redirected in step S306 yet.
It should be noted that, in step S308 the performed processing processing performed with redirected unit 240 identical, specifically can, with reference to the description of counterweight directed element 240 above, not repeat here.
According to the URL reorientation method of the embodiment of the present invention, in advance the redirected rule in configuration file is sorted out according to the first class catalogue of request path, and adopt data dictionary to preserve, carrying out URL while being redirected, first by data dictionary, search first class catalogue, found and carried out again matching regular expressions, otherwise do not carry out matching regular expressions, avoided directly carrying out the situation of matching regular expressions failure, thereby improved the efficiency of match hit, and then improved the speed of resource in the redirected processing speed of URL and client-access server.And what carry out matching regular expressions is only a subset of all redirected rules, has further improved the redirected processing speed of URL.
It should be noted that, above-mentioned step S302 is optional step, and described URL reorientation method can not comprise described step S302, and data dictionary is input in server end after can be pre-configured, by described URL reorientation method, is used.
According to URL reorientation method and the device of the embodiment of the present invention, for ease of the realization of code, when carrying out website design, the first class catalogue for the redirected configuration file of URL corresponding to this website can be defined as:
