Embodiments of the present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, in the method and system embodiment of acquiring network address for embedded terminal of the present invention, the method for acquiring network address for embedded terminal comprises the steps:
Step S11 server access named web page, resolve its script file, obtain expression formula for search: server timer access named web page, news pages of Yahoo etc. for example, these web page addresses can not change, but, its content is constantly to change, that is to say the chained address that on above-mentioned named web page, has a plurality of variations, the content that each chained address is corresponding different, in this step, these address setting of server timer access are the webpage of portion within it, and resolve the script file of these webpages one by one, obtain the expression formula for search of each chained address on it.
Step S12 is to expression formula for search classification automatically, autoabstract and metadata analysis: in this step, the expression formula for search that previous step is obtained in rapid is handled, these processing comprise automatic classification, produce Summary file and its metadata is analyzed automatically, create text title, keyword, search actions such as link address, source, like this, just each chained address being put in order as label with keyword or title is an inventory item or an information.This inventory item or an information are just corresponding to a chained address.So, just can take out the chained address comparison of carrying in the request that a chained address and built-in terminal send separately as label with its keyword or title.
Step S13 changes the form of above-mentioned data: the information translation that previous step is obtained suddenly is for ease of the form of database storage, and the benefit of doing like this is to be convenient to these information are stored, and also is convenient to search in database these information.
That step S14 obtains upgrading, be kept at the address list in the database: in this step, the result who obtains in the above-mentioned steps is left in the address list of server database.In the present embodiment, the above-mentioned information or the inventory item that obtain are inserted address list one by one, if there is label identical, the item before covering when inserting; If there is not identical label, then increase an inventory item, the above-mentioned information adding that obtains is got final product.
Step S21 built-in terminal sends request: in this step, built-in terminal sends the request that obtains Web content, and in the present embodiment, built-in terminal is to send this HTTP request by built-in Wi-Fi wireless communication module.As we point out in front, built-in terminal is not to move this request of sending by the online the same with PC, usually, this built-in terminal is owing to be limited to the hardware of himself, in the link label of some settings, select, the chained address of obtaining before having in these labels just comprises these chained addresses in the above-mentioned request.
Step S22 server parses should request, and obtain wherein chained address: in above-mentioned steps, built-in terminal sends request, and this asks serviced device to receive, and, these requests of server parses, the chained address that obtains wherein being comprised.What deserves to be mentioned is that the request of this built-in terminal is sent must be at server, server receives this request and also is bound to its decomposition.In addition, the action of above-mentioned server is carried out on the backstage, uses the user of above-mentioned built-in terminal can not feel.
Is this address of step S23 identical with address of the same name in the server? in this step, more above-mentioned by the address of the same name comparison in the database in chained address that obtains in the request and the server, judge whether these two addresses are identical, if these two addresses are identical, illustrate that the address list in this terminal is up-to-date, server no longer upgrades the address list in the above-mentioned built-in terminal, directly transmits the request that above-mentioned built-in terminal is sent, execution in step S24; If above-mentioned two address differences illustrate that then the address list in the above-mentioned built-in terminal is old, server need upgrade execution in step S24 to this address list.
The above-mentioned request of step S24 server forwards: in this step, because server itself judges that the chained address of this request is effective or up-to-date, therefore, server is not made any change to this request, directly should ask to transmit to this chained address.
Step S25 server accesses address list in the database. in this step, because server itself judges that the chained address of this request is effective or up-to-date, therefore, server accesses the address list in the database, prepares to upgrade the chained address of this built-in terminal.
Step S26 changes above-mentioned address list form: since before leave in the chained address in the database time its form made change, therefore, in this step, need be converted into above-mentioned terminal receives, RSS form to the form of these chained addresses again.
Step S27 sends above-mentioned address list to built-in terminal, the address list content of new terminal more: in this step, server is issued built-in terminal with above-mentioned through the chained address after the format conversion, upgrades the chained address of this built-in terminal, simultaneously, above-mentioned server is no longer transmitted this request, and built-in terminal will before the request that the send address that changes link, send once more, at this moment, server begins executive program from above-mentioned steps S21 once more, promptly jumps to step S21 from this step.
In the present embodiment, above-mentioned steps S11 can be to be a part to step S14, and step S21 can be considered as an other part to step S27, above-mentioned two parts connect each other, but have any different, step S11 can carry out to step S27 with step S21 simultaneously to step S14, also can successively carry out, and its last purpose is that the address list in the server database is updated to the current effective chained address in a word.
