Proxy type: Transparent proxy anonymous agent obfuscation agent and high stealth proxy. Here are some Python crawlers using the agent knowledge, there is a proxy pool class. It is easy to handle all kinds of complex crawl problems in the work. Urllib module using proxy urllib/urllib2 is cumbersome to use proxies, you need to build a Proxyhandler class, then use that class to build the opener class of the Web page open, and then install the opener in the request. The proxy format is "http ://127.0.0.1:80 ", if you want the account password is" http://user:password@127.0.0.1:80 ". proxy=" http://127.0.0.1:80 "# Create a Proxyhandler object Proxy_support=urllib.request.proxyhandler ({' http& #3

4.10.Java Foundation-Agent

Introduction: Basic Concepts-Provides a proxy object for an object, and the proxy object Controls access to the original object, that is, the client does not manipulate the original object directly, but indirectly manipulates the original object through the proxy object. Generally speaking, like to buy train tickets, originally we need to train station to buy tickets, now set up a ticket, you can buy tickets directly through the ticket point. The implementation of agent can be divided into static agent and dynamic agent, and dynamic agent is divided into JDK dynamic agent and Clgib dynamic agent. Static proxy observation code can discover that each proxy class can serve only one interface, so the program opens

5. In-depth understanding of Java dynamic Agents

Introduction: Proxy mode is a common Java design pattern, his characteristic is that the proxy class and the delegate class have the same interface, the proxy class is mainly responsible for the delegate class preprocessing messages, filtering messages, forwarding messages to the delegate class, and post-processing messages. There is usually an association between the proxy class and the delegate class, and the object of a proxy class is associated with an object of a delegate class, and the object of the proxy class does not actually implement the service, but instead provides a specific service by invoking the related method of the object of the delegate class. The proxy class can be divided into two types according to the agent's creation period.

6. Understanding of SPRINGAOP

Introduction: AOP (Aspect Orient programming), as a complement to object-oriented programming, is widely used to deal with some system-level services with crosscutting properties, such as transaction management, security check, cache, object pool management, etc. The key to AOP implementations is the AOP proxy, which is automatically created by the AOP framework, which can be divided into static proxies and dynamic proxies, in which static proxies are compiled using the commands provided by the AOP framework to generate an AOP proxy class at compile time, which is also referred to as compilation While the dynamic agent generates an AOP dynamic agent in memory with the help of JDK dynamic agent, CGLIB, etc.
