Incorrect matching is difficult to find, so it is important to plan and test in advance.For example, if you confirm a phone number in the Web form, you may only need to meet ten numbers in any format. However, if you want to separate phone numbers from a large number of texts, you may need to authenticate and exclude incorrect matching.Write down some cases when considering the data you want to match. Write down some code for the case to test your regular expression. For any comp

For any complex regular expression, it is best to write a small program to test it. the specific form below can be used.In Perl: #! /Usr/bin/perl My @ tests = ("314-555-4000 ","800-555-4400 ","(314) 555-4000 ","314.555.4000 ",555-4000 ","Aasdklfjklas ","1234-123-12345"); Foreach my $ test (@ tests ){If ($ test = ~ M/(? # Optional parenthesesD {3} # required telephone area code)? # Optional parentheses[-S.]? # The

team.Deciding what to match is actually a balance between matching error results and missing correct results. If your regular expression is too strict, it will miss some correct matches; if it is too loose, it will produce an error match. Once a regular expression is issued to the actual code, you may not notice both. Consider the example of the phone number above. It will match "800-555-4000 =-5355 ". Incorrect matching is difficult to find, so it is important to plan and test in advance.For e

The VAIO Pro combines the benefits of VAIO Z with VAIO x, VAIO Pro uses the hexagonal line design of the VAIO Z, the carbon-fibre fuselage and the aluminum alloy back cover panel, and the overall size and thickness of the VAIO X is the ultimate slim, thin, light and hard to imagine.

. The IP address and subnet mask given above are only standard forms. Users can also use additional IP and subnet masks, such as the IP address set to 10.0.0.1, and the subnet mask set to 255.255.255.128, depending on their needs. However, in order to facilitate the classification and management, in the LAN set IP address, it is recommended that the standard classification to set. The IPV6 address is composed of 16 bytes and is divided into 8 segments. Each paragraph consists of 16 bytes and i

table with the destination address as the keyword to obtain the required RS Sh Source Address Hash Dispatch (source Hashing) finds a static hash table with the source address as a keyword to obtain the required RS Lc The minimum number of connections is dispatched (Least-connection), and the Ipvs table stores all active connections. Send a new connection request to the smallest current number of connections RS

overloaded, the return is empty.4, DH target address hash: Ibid, just now extract the destination address of the IP to do the hash.Advantages: Both of the above algorithms can achieve the same user access to the same server.5, LC Minimum connection. Prioritize requests to servers with few connections.Advantage: The load on each server in the cluster is more uniform.6, WLC weighted least connection. On the basis of the LC, weights are added to each se

weighted scheduling algorithm. We set weights for each server weight, load-balancing scheduler according to the weight of the dispatch server, the server is called the number of times with the weight of the proportional. Advantages: Considering the different processing capabilities of the server SH Original address hash: Extract User IP, according to hash function to get a key, and then according to static mapping table, investigate the corresponding value, that is, target server IP.
