Code as above; Write three functions of order500, order200 and orderNormal respectively, and process their own business logic in the functions respectively. If their own functions cannot be processed, they will return the string nextSuccessor to pass it back, then encapsulate the constructor Chain, pass an object fn into it, and have their own attribute Successor. There are two methods setNextSuccessor and passRequest on the prototype. The method setNextSuccessor specifies the order of nodes in the responsibility chain, and saves the corresponding method to the attribute this.Successor, chainOrder500. SetNextSuccessor (chainOrder200); ChainOrder200. SetNextSuccessor (chainOrderNormal); Specifies the order in the chain, so this.Successor references the order200 method and the orderNormal method, so if chainOrder500.passRequest (1, true, 500) is called for the first time, the order500 method is called, output directly, and chainOrder500.passRequ is called for the second time.

We know that IPTables acts according to rules. Let's talk about rules. Rules are actually predefined conditions for network administrators. Rules are generally defined as "if the packet header meets such conditions, this packet will be processed in this way". The rules are stored in the packet filtering table in kernel space, specifying the source address, destination address, transport protocol (such as TCP, UDP, ICMP), service type (such as HTTP, FTP, and SMTP), and so on. When packets match the rule, iptables processes these packets according to the methods defined by the rule, such as accept, reject and drop. The main task of configuring a firewall is to add, modify, and delete these rules.
