This article, in conjunction with the previous article, "Python uses Youdao translation to achieve the" language translator "function" of the implementation code, processing, to achieve the request server to hide user-agent.There are two general ways that Python implements hidden user-agent:(1) Before the request object is generated (req in the example below), a dictionary-type head is passed into the urllib.request.Request (URL, data, head) as a para

When we learn spring, we know that spring has two main ideas, one is the IOC, the other is AOP, and for IOC, dependency injection doesn't have to be said, and for spring's core AOP, we not only need to know how to satisfy our function through AOP, What we need to learn is how the underlying is a principle, and the principle of AOP is the dynamic agent mechanism of Java, so this essay is a review of the dynamic mechanism of java.In the dynamic

First, the origin of dynamic agentsAgent refers to: to each specific class to write a proxy class, in the future to use a specific class, as long as the object to create its proxy class, and then invoke the proxy class method can be, but if there are many specific classes, it is necessary to create a lot of proxy class can, this is obviously not suitable, the dynamic agent was born.Second, there are 2 ways to implement dynamic

Zabbix Agent source code compilation and Installation Introduction: Sort out Zabbix Agent separately. 1.

You can specify the -- enable-agent parameter to install the Agent.One is to install the Zabbix

The concept and function of agent in programTo add some system functionality to the various methods that already exist for the target class with the same interface, such as Exception handling, logging, calculation method run time, transaction management, and so On.Proxy Architecture Diagram:　　If you are managing with Factory mode and configuration files, you do not need to modify the client program, whether you want to use the target class or the prox

Proxy mode:　Provides a proxy for other objects to control access to this object. The proxy mode is divided into two main categories:　　　　static Proxy: The source code is generated automatically by the programmer or a specific tool, and then compiled. Before the program runs, the. class file for the proxy classes already exists.　　　　Dynamic Proxy: when the program is running, it is created dynamically using the reflection mechanism1. Static agent relativ

One of the underlying technologies used by Spring AOP is the dynamic agent technology of Java. The dynamic agent technology of Java is mainly around two classes.Java.lang.reflect.InvocationHandlerJava.lang.reflect.ProxyThe first step is to explain how the Java Dynamic Agent is implemented from the code level.Business Logic Interface:　　/** * Create a Human interfa

There are 2 implementations of Java dynamic Agents, Jdkdynamicaopproxy and Cglib2aopproxy.Spring's AOP is all used in this 2 implementation, JDK Dynamic agent is implemented by the internal reflection mechanism of Java, with Proxygenerator.generateproxyclass (... ) to generate the bytecode, the cglib dynamic proxy generates a subclass of the proxy class (so the final class is not dynamic proxy), and the underlying is implemented with ASM. In general,

Recently in the study of this Java SSH three framework, when see this spring AOP (aspect-orinted-programming), which mentioned this Java dynamic Proxy mechanism, this dynamic agent, I seem to have seen before, But that's a design pattern. So one time to search for this dynamic agent, the dynamic agent to conduct a study to record their progress.Spring's AOP progr

Dynamic Agent for JavaProxy modeProxy 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 clas

Proxy modeBrief introduction:Instead of manipulating the actual object directly, the actual object is manipulated indirectly through the proxy object, and the specific user does not know the specificobject or the actual object.Static proxy1.

When using the AWS Cloud Service, 90% uses the ELB service as a load-balanced solution, and using Elb is much more convenient than building load balancing yourself. 　　The main benefits of are: 1. Can monitor the health status of the instance at any time; 2. When the server is not normal, the ELB alert policy will automatically send messages to notify the Operators 3. When the server load reaches the threshold, the new server is automatically joined to the cluster through the auto scanning, a

Because only the get and post methods can be used in Axios to make request data cross-domain Access data without JSONP and so on if you want to use Axios to do cross-domain access directly it is not possible to configure the agent why do I need to configure the agent? The reason is because the client is requesting that the data on the server has cross-domain problems and that the servers and servers can req
