Detailed description of the invention
Access technology based on client and server, the present invention autopolling mechanism by domain name, real
Now without change client can intelligence switching server request domain name technology, thus reduce maintenance cost,
Shorten renewal and the turn-on time of server, improve user experience.Describe in detail below in conjunction with accompanying drawing
Each specific embodiment of the present invention.
As it is shown in figure 1, provide a kind of user end inserting method in one embodiment of the invention.The party
Method can automatically access new service in time primarily to realize client when server end generation address change
The mode of device end.This user end inserting method comprises the following steps S100 to step S300.
In the step s 100, client reads XML allocation list, and this XML allocation list records at least one
Individual server end domain name.The hereinbefore domain name mentioned refer to main frame (host), subdomain (sub domain) and
The Internet address (address) that the form in territory (domain) represents, the IP address (IP address) represented with numeral
Relatively.The most first attribute civil aviaton of domain name addresses, restriction domain name (full qualified domain name).
After generally computer keys in domain name inside Web address field, domain name addresses is translated as this domain name by existing dns server
Behind corresponding IP address, could normal linking objective server.
In one embodiment of the invention, XML allocation list can be only fitted to client this locality, it is also possible to is
It is arranged on server end.If being arranged on server end, when needs read XML allocation list, client
Can first from server end download XML allocation list to this locality, read XML allocation list the most again.
Additionally, in order to ensure that the XML allocation list of local preservation keeps consistent with server side content, then exist
In one of them embodiment of the present invention, when server end domain name has variation, server side can update XML
Allocation list, and after client is successfully connected server end every time, all download XML configuration from server end
Table is to local.Therefore, in another embodiment of the present invention, as in figure 2 it is shown, before step S100
Further comprising the steps of:
Step S110, downloads XML allocation list to this locality from server end.
But, first after server end downloads XML allocation list, update the XML configuration that this locality preserves
The step of table can be in the following ways.
Such as, when receive from server end feedback update notification or client be successfully connected every time
After server end, the XML allocation list recorded on server end can be extracted in order to update local preservation
XML allocation list.
Or, as it is shown on figure 3, step S121 is first carried out: extract the XML recorded on server end and join
Putting the version number of table or update the marks such as timestamp, this mark can be used as judging the XML configuration of local preservation
Table is the most consistent with the XML allocation list that server end preserves, the XML configuration that server end herein preserves
Table can be the XML allocation list of recent renewal.
Then, perform step S122: judge on server end the XML allocation list of record version number or
Update timestamp etc. and identify whether consistent, the most then with the correlated identities in the local XML allocation list preserved
The XML allocation list that different update client this locality preserves, otherwise, then extract the XML recorded on server end
Allocation list is in order to update the XML allocation list of local preservation.Then, in above-mentioned steps S100, then change
For reading the XML allocation list that this locality preserves.
In another embodiment of the present invention, XML allocation list except recording at least one server end domain name,
The version number of XML allocation list can also be recorded, XML allocation list is positioned at content distributing network (CDN, i.e.
Content Delivery Network) on storage address the withdraw information corresponding with server end domain name and
Storage address or version number corresponding update in timestamp etc. at least one.Above-mentioned with server end domain name pair
The information of withdrawing answered at least includes withdrawing time started, the end time of withdrawing, withdrawing the time limit and withdraw bulletin
Any one in Deng.The storage address that above-mentioned XML allocation list is positioned on content distributing network can configure many
Individual.
In step s 200, at least one the server end domain name in clients poll above-mentioned XML allocation list,
Initiate HTTP request.In the present embodiment, according to the server end domain name described in above-mentioned XML allocation list,
HTTP request is initiated, in order to realize poll successively to the server end of the server end domain name indication recorded.
And the polling sequence of server end domain name can be to randomly choose in XML allocation list in above-mentioned XML allocation list
The server end domain name recorded, or select according to order after the renewal time-sequencing of server end domain name,
Or order selects the server end domain name described in XML allocation list, or is by traveling through above-mentioned XML
The polling sequence selection modes such as the Servers-all end domain name described in allocation list.HTTP referred to herein
Request refers to the request message from client to server end, including: the request in message first trip, to resource
Method, the identifier of resource and the agreement etc. of use.
In step S300, client judges whether to receive the response message from server end.If existing
From the response message of server end, then set up the connection with this server end；Otherwise, then terminate or read
The information of withdrawing described in XML allocation list that takes is in order to show.
In one of them embodiment of the present invention, above-mentioned client judges whether to receive from server end
Step S300 of response message include:
In step s 200, the Servers-all end territory of record in the complete above-mentioned XML allocation list of clients poll
After Ming, perform judge whether to receive step S300 of the response message from server end, if exist from
The response message of server end, then can randomly choose a response message from the multiple response message received
Corresponding server end also sets up connection therewith；Or order selects one from the multiple response message received
Server end that individual response message is corresponding also sets up connection therewith；Or from the multiple response message pair received
The server end answered selects meet pre-conditioned server end and set up connection therewith.Certainly, if
In the complete above-mentioned XML allocation list of clients poll after the Servers-all end domain name of record, from server end
Response message only one of which, then just directly set up connection therewith.If the complete above-mentioned XML allocation list of poll is remembered
Do not receive response message yet after the Servers-all end domain name of record, then terminate or read in XML allocation list
That records withdraws information.
The present embodiment is mentioned pre-conditioned can be distance the closest (thing on such as network of client
Reason distance) server end, the optimum server end of network transmission channels, server end that resource is the abundantest
Etc. the server end that relatively optimizes.Network configuration can be optimized, it is to avoid all clients by the present embodiment
The most only connect some server end, cause network blockage.
Additionally, in one of them embodiment of the present invention, above-mentioned client judges whether to receive from clothes
Step S300 of the response message of business device end includes:
In step s 200, the server end domain name indication that client records in XML allocation list
After server end initiates HTTP request, perform once to judge whether that receiving the response from server end disappears
Step S300 of breath, if there is response message, server end corresponding with this response message the most immediately leads to
Letter connects, if now not receiving response message, then makes client select another to take from XML allocation list
Business device end domain name, and return the server end domain name that the above-mentioned client of execution records in XML allocation list
The server end of indication initiates the step of HTTP request, until receiving response message, and disappears with this response
The server end that breath is corresponding is set up and is connected.If the Servers-all end of record in the complete above-mentioned XML allocation list of poll
Do not receive response message after domain name yet, then terminate or read to withdraw information described in XML allocation list.
The present embodiment can simplify access process, shortens the time of access server side.In this embodiment, visitor
Family end selects the mode of a server end domain name can be to randomly choose XML configuration from XML allocation list
Server end domain name described in table, or according to order choosing after the renewal time-sequencing of server end domain name
Select, can also is that order selects the current server end domain name etc. recorded in XML allocation list.
In above-mentioned steps S300, above-mentioned foundation can use in this area with the step of the connection of this server end
Conventional connected mode, after usual client initiates HTTP request, if successful connection, then
Server end can send response message, otherwise, then the unsuccessful notification message of feedback link or do not feed back appoint
What is the need cease.In each embodiment above-mentioned, when not receiving the response message of server feedback, such as Fig. 4 institute
Show, in one of them embodiment of the present invention, read in XML allocation list in above-mentioned steps S300 and remember
In the step of the information of withdrawing carried or when step S300 does not receives the response message from server end
Time also include:
Step S310, obtains current time stamp, it is judged that whether current time is described in XML allocation list
Withdraw in the time range of information indication, the most then extract and withdraw information described in above-mentioned XML allocation list
It is shown, otherwise, then client processes voluntarily or terminates to connect, or again initiates above-mentioned steps
S100 accesses again to the process of step S300.
The present embodiment is withdrawn information indication time range can by the information of withdrawing is withdrawn the time started,
Withdrawing end time, the time limit of withdrawing etc. calculates acquisition.
Based on each embodiment above-mentioned, in another embodiment of the present invention, read in above-mentioned steps S100
Before taking the step of XML allocation list, also include:
Judge that the network of client connects whether fault, if it is not, then perform the step of described reading XML allocation list
Rapid S100, on the contrary terminate, or perform following step step S131 as shown in Figure 5 to step S134.
In the present embodiment, by by client go ping preset domain name judge client network connect be
No there is fault, such as preset domain name can from default domain name table unrestricted choice, preset in domain name table and show
Home and abroad domain name, as domestic for Baidu (http://www.baidu.com), is abroad google
(http://www.google.com) etc..Gone the corresponding domain name of ping (domestic for Baidu by client
(http://www.baidu.com), is abroad google (http://www.google.com)), if can not ping
Logical, illustrate that the network of first client is problematic, to Client-Prompt network problem；If can lead to by ping
Corresponding domain name, then explanation client network is no problem, it may be possible to domain name or server go wrong.
Based on each embodiment above-mentioned, in another embodiment of the present invention, as it is shown in figure 5, above-mentioned
Before step S100 reads the step of XML allocation list, also include:
Step S131, according to a front successful connection or default server domain name, initiates HTTP request,
Obtain conditional code；This conditional code refers to system mode code or the mistake returned according to HTTP request by operation layer
Code etc., such as the flag value of operation layer feedback.
According to described conditional code, step S132, judges whether HTTP request asks successfully, if it is not, then perform
The described network judging client connects step S120 of whether fault.And when judging according to described conditional code
When HTTP request is asked successfully, then perform step S133.
Step S133, it is judged that the attribute of described conditional code；
Step S134, updates, according to the attribute of described conditional code, the XML allocation list that client is locally stored.
When generally conditional code is 200, represents and ask successfully；And conditional code be another about definite value time, Ke Yipei
Put different processing modes.Such as, when conditional code is the first property value (such as-301), the most now business
Layer interface information normally returns, and this state simply tells that webHost of client this time request is general soon
Will go out of use, need client to update the XML allocation list that this locality preserves, in order to prevent backstage from artificially joining
Put and make mistakes, therefore next time request be polled with up-to-date webHosts, until find one can be with normal request
WebHost, if can not find, judge current time in system stamp whether start and end in xml configures
Between, if, then show and withdraw public information, if not existing, client does acquiescence close friend's prompting.Therefore,
When conditional code is the first property value (such as-301), step S134a in Fig. 6 can be performed and extract service
After the XML allocation list of storage is in order to update locally stored XML allocation list on device, then perform above-mentioned steps
S100 comprises above-mentioned steps S100 to step S300 to the process or Fig. 1 to Fig. 5 of step S300
Process.
When described conditional code is the second property value (such as-404), then the server being due up withdraws maintenance,
Need to update and the XML allocation list that client is local withdraws the contents such as information, update caching xml herein
During allocation list, in order to prevent from frequently writing caching, it is therefore desirable to the version number in the xml configuration downloaded
Compare with the version number of local cache, if local xml version number is more than or equal to just having downloaded, the most not
Update local cache, local cache to be updated, read up-to-date notice information of withdrawing after renewal and show
Client.Therefore when conditional code is the second property value (such as-404), then by step S121 in Fig. 3
Update locally stored XML allocation list to step S122 process, after perform again above-mentioned steps S100 to step
The process of rapid S300 or Fig. 1 to Fig. 5 comprise above-mentioned steps S100 to the process of step S300.
Or, as shown in Figure 6, when conditional code is the second property value (such as-404), then below execution
Step:
Step S121a: extract the version number of the XML allocation list recorded on server end or update timestamp
Deng mark, this mark can be used as judging the XML whether the XML allocation list of local preservation preserves with server end
Allocation list is consistent；
Step S122b: judge the version number of the XML allocation list recorded on server end or update timestamp
Etc. identifying whether that the correlated identities with the local XML allocation list preserved is consistent, the most do not update client
The XML allocation list that end this locality preserves, the information of withdrawing in execution extraction XML allocation list that redirects is shown,
Otherwise, then extract the XML allocation list recorded on server end in order to update the XML allocation list of local preservation,
The information of withdrawing in execution extraction XML allocation list that redirects the most again is shown.The present embodiment can effectively simplify
Part control flow, make that integrated operation is easier, flow performing more rapidly, reduce interaction time.And
The phase that can be found in hereinbefore is resolved about extracting the correlation step that in XML allocation list, the information of withdrawing is shown
Close explanation.
In the present embodiment, the decision error types such as the error code returned according to HTTP request also determine whether
Download xml document is in order to update locally stored XML allocation list, thus is resolved newly by new allocation list
