Agent modeProxy proxy mode is a structural design pattern, the main problem is: The problem of direct access to the object, such as: the object to be accessed on the remote machine. In object-oriented systems, there are some objects that for some reason (such as object creation overhead, or some operations require security control, or require out-of-process access), direct access can cause a lot of trouble for the user or system structure, and we can

First, prefaceIn some cases, a customer does not want or cannot refer directly to an object, and an indirect reference can be achieved by a third party called a "proxy". A proxy object can act as a mediator between the client and the target object, and can remove content and services that the customer cannot see or add additional services that the customer needs through the

AOP is one of the core of the spring framework, and it plays a very important role in the application and is the foundation of other components of spring. It is a facet-oriented programming idea. On the basic knowledge of AOP, I believe most of the children's shoes are already at hand, we skip this part to explain the underlying implementation mechanism of the core functions of AOP: How to use dynamic proxy to achieve cut-plane interception. The block

Python scans the proxy and obtains the instance of the available proxy ip address, pythonproxy Today, I wrote a practical tool to scan and obtain available proxies. First of all, I first Baidu found a Website: http://www.xicidaili.com as an Example This website has published many available proxy ip addresses and ports at home and abroad. Let's analyze it as we us

When it comes to proxy servers, most people should be more familiar with it. Remember when in school because the campus network can not access foreign sites, so often use agents to visit foreign sites.
