How to implement a simple interceptor operation in Java through dynamic proxy
Article Introduction:1. Proxy Before using dynamic proxies to implement interceptors, let us first briefly understand what Java proxies are. Proxy, as the name suggests, does not directly operate the object being proxied (hereinafter referred to as the target object, which sounds more comfortable), but indirectly uses the methods in the target object through a proxy object. Agents are divided into two modes, one is static agent and the other is dynamic agent. Next, write an example of a static proxy. Whether it is a static proxy or a dynamic proxy, the target object must implement an interface. Note that if you use the proxy provided by cglib, you do not have to implement the interface, but implement it through a subclass. We will not discuss this method for the time being. . (1) First define an interface public

Introducing Nginx, forward proxy and two examples of implementing reverse proxy
Article Introduction:Nginx is a high-performance open source web server and reverse proxy server with lightweight, scalable and high-concurrency processing capabilities. It is widely used to build reliable and efficient web applications and services. Forward proxy is a proxy server application mode that acts as a middleman for the client to help the client communicate with the target server. For example, when a client cannot access certain websites directly, access can be achieved through a forward proxy. In this case, the client sends a request to the proxy server, and the proxy server forwards the request to the target server. Ultimately, it is assumed that there is a network environment within the company, and employees need to access external Internet resources through the proxy server. In this case, the proxy server acts as a forward proxy and receives

How to configure multiple WeChat under Nginx reverse proxy port 80
Article Introduction:Detailed explanation of configuring multiple WeChat projects under nginx reverse proxy port 80. If we want to access the WeChat public account platform for development, we need to fill in the server configuration, and then implement the business logic according to the interface document. However, the WeChat official account interface only supports interface 80 (port 80). Due to business needs, we need to publish two projects that require WeChat authorization under one official account domain name. What should we do? We can use nginx server as a reverse proxy to solve this problem. The nginx server externally accesses port 80, and then accesses different projects internally based on different url parameters. The nginx configuration is as follows: Open /usr/local/nginx/conf/nginx.confworke

Use PHP code to implement the request proxy and reverse proxy of Baidu Wenxinyiyan API interface
Article Introduction:Using PHP code to implement the request proxy and reverse proxy of Baidu Wenxin Yiyan API interface Overview: Baidu Wenxin Yiyan is an API interface that provides various random sentences and famous quotes, which can be used in websites, APPs and other applications. But for some reasons, we may need to call the API with the help of a proxy or reverse proxy to avoid some limitations or better control the requests. Request proxy: Request proxy refers to sending our request to an intermediate server (proxy server), and then the proxy server sends it to Baidu Wenxinyiyan A on its behalf

How to build a simple forward proxy server using Golang
Article Introduction:Golang is a powerful programming language that is increasingly favored by developers in network programming due to its efficiency and flexibility. In network programming, the proxy server is one of the very important functions. It provides a transfer station between the client and the target server, forwards the client request to the target server, and returns the response of the target server to the client. end. This article will introduce how to build a simple forward proxy server using Golang. 1. Overview A forward proxy is a network application that is typically used between a client and a target server

What proxy IP does a crawler generally use?
Article Introduction:Crawlers generally use high-anonymity proxy IPs. Because crawlers require high anonymity, only proxies with high anonymity, security and stability, that is, high-anonymity proxies, are suitable for crawlers. The high-anonymity proxy does not change the client's request, so that it looks to the server like a real client browser is accessing it, and the server will not think that we are using a proxy.

How to build a simple Nodejs proxy server
Article Introduction:With the development of the network, we increasingly need to request files on remote servers through the network. However, in some cases, we will be troubled by issues such as unstable access to servers in different regions and poor network environments. At this time, we can solve these problems through proxies, and Nodejs happens to provide good support. As a server-side development environment, Nodejs's built-in http module provides APIs for processing HTTP requests and responses. We can use these APIs to implement proxy requests. in the text

Open source large-model AI agent operating system: control AI agents like Windos
Article Introduction:This article is reprinted with the authorization of the AIGC open community. Please contact the source for reprinting. To learn more about AIGC, please visit: 51CTOAI.x community https://www.51cto.com/aigc/ Last year, the emergence of AutoGPT made us realize the powerful automation capabilities of AI agents and created a new AI Agency track. However, there are still many problems that need to be solved in sub-task scheduling, resource allocation and collaboration between AI. So researchers at Rutgers University developed AIOS, an AI agent operating system with large models at its core. It can effectively solve the problem of low resource call rate as the number of AI agents increases. It can also promote context switching between agents and realize concurrent agent merging.

Example analysis of dynamic proxy and static proxy in Java
Article Introduction:0. Agent Mode Why should we learn the agent mode? This is the classification of SpringAOP's underlying [SpringAOP and SpringMVC] proxy modes: Static proxy Dynamic proxy 1. Static proxy In static proxy, our enhancement of each method of the target object is done manually (the code will be demonstrated later_) , very inflexible (for example, once a new method is added to the interface, the target object and proxy object must be modified) and troublesome (_need to write a separate proxy class for each target class). There are very few actual application scenarios, and there are almost no scenarios where static proxies are used in daily development. Role analysis: Abstract role: Generally, interfaces or abstract classes are used to solve the problem. Real role: the role of the agent. Agent role: the real role of the agent.

Example analysis of Java dynamic proxy and static proxy
Article Introduction:1. Static proxy Static proxy uses static proxy. The proxy class and the proxy class implement the same interface. The proxy class also holds a reference to the proxy class. In this way, when we need to call the method of the proxy class, we can pass Do this by calling a method on the proxy class. Example: Suppose the leader's job is to hold meetings and evaluate employees. First define an interface: packagecom.sharpcj;publicinterfaceIWork{voidmeeting();intevaluate(Stringname);} and then define the leader class: packagecom.sharpcj;importjava.util.Random;publicc

What is the principle of JavaScript proxy mode?
Article Introduction:In JavaScript, the principle of the proxy pattern is to provide a substitute or occupier for an object in order to control access to it; by providing a proxy for an object, and the proxy object controls the reference to the original object, it is a Object structural pattern.
