a)?Backslash?(“\”)?is?represented?as?“\\”.
b)?Comma?(“,”)?is?represented?as?“\,”?in?individual?substring?entries。
CSV form original data record file format is defined as follows:
Table 2
Modules function in data analysis module 14 is as described below respectively:
Unicode support module 141:
The search engines such as Google acquiescence uses UTF-8 as the coding of NON-ASCII, and this is mainly to consider international adaptability.Chinese character has the coding of our country oneself, as GB2312, and GBK, they are all with double-byte representation, and it is block code, is different from a variable-length encoding to nybble of the employing of UTF-8.Chinese character encoding is widely used on windows operating system and other software at home.Must consider character-coded conversion when surfing the Net Chinese character string coupling or extraction.
Mail tabulation identification module 142:
The mail that uses Mail Clients to send is generally used smtp protocol, and its mail head has set form, and receiving mail protocol is also that set form is arranged as POP3, and this provides convenience to doing mail recognition.New mail sending and receiving agreement IMAP is also similar, and just form is variant.But the exchange server email message of Microsoft has its own special-purpose cover agreement, can not use Exchange server because of home network and make mail server, so can not realize identification in native system.Realized extracting recipient's list of Mail Clients receiving and dispatching mail in native system, sender, the list of making a copy for, close list, the mail matter topics of sending.The mail that the webpage mailbox sends is in the information extraction of use characteristic coding mode.
GB modular converter 143:
In URL, two bytes of Chinese character encoding are carried out escape with the % symbol, in order to represent hexadecimal Chinese character encoding with ASCII character.Except above-mentioned UTF-8 Chinese character encoding, some website in the country such as Baidu all directly use GB representation Chinese character, and it is constant to keep the ASCII character coding, when processing the Chinese character string, this module has been carried out flexible processing, has solved various codings and has deposited and avoid occurring the problem of mess code.
Search identification extraction module 144:
Baidu's keyword query acquiescence is used the GBK code, and google keyword query acquiescence is used the UTF-8 coding.Various search engines are searched for fixing inquiry string, but as escape character, the space, comma is processed variant, and this submodule solves these difference, and various search keys can former state be restored.
Condition code identification extraction module 145:
This submodule is a submodule the most complicated in data analysis module 14, it utilizes pre-set regular expression to mate and extracts useful information, regular expression is powerful, use flexibly, pass through appropriate design, can make coupling simple efficient, avoid taking too many system resource and cause networking speed to be affected.
Network control module 15:
Data reporting module 16:
This module is responsible for regularly sending to file server the original recorded data that generates.Therefore output file writes in ramfs, needs to control the internal memory use amount, prevents that ramfs is full of, and in time process to surpass the file that limits the time limit, need to consider following some:
1. during behavior, can not report the sky data without online when the LAN side.
When 2. reporting purpose unreachable, gateway does not overstock too many log file.
3. when repeatedly attempt unreachable after, gateway stops data acquisition.Data will be compressed and encryption before sending.
4. produce when analysis package writing time, kernel does not provide the time
5. the direct invoke script of FTP periodic report function and active reporting is uploaded ftp, need withdraw from releasing resource after having passed.
6. repeatedly file server unreachable after, send out the message informing system and stop data collection, until recover.
7. after successfully reporting, with the associated documents deletion, filename meets unified regulation, comprises gateway identification and gets sequence number, reports date and time.
8. when surpassing reservation threshold, automatically deletes by the file that overstocks the early stage file that generates.
9. set the static routing of file server, if special-purpose management PVC is arranged, file server is by management PVC transmission, otherwise by online PVC transmission, this does not provide the modification interface.
