Course Introduction:With the popularity of the Internet and the increase in data volume, web crawlers have become an indispensable part of various industries. As a high-performance programming language, Go has become the language of choice for more and more crawler projects. However, in actual development, we often need to control the crawler thread, such as when we need to stop or restart the crawler. This article will discuss how to stop the crawler thread from the perspective of Go language. 1. Methods to implement thread stopping in Go language. In Go language, a thread can be represented by a goroutine. By default, g

Course Introduction:In the implementation of web crawlers, asynchronous multi-threading can greatly improve the efficiency of crawling. As a mainstream programming language, PHP can also implement asynchronous multi-threaded crawlers through concurrent programming. This article will introduce the specific implementation method. 1. Overview of asynchronous multi-threaded crawlers Asynchronous multi-threaded crawlers mainly rely on two technologies: asynchronous IO and multi-thread processing. In traditional synchronous IO, the thread will wait for the IO operation to complete before proceeding to the next operation. In asynchronous IO, threads can perform operations while waiting for IO operations.

Course Introduction:Introduction to concurrency and multi-thread processing skills of PHP crawlers: With the rapid development of the Internet, a large amount of data information is stored on various websites, and obtaining this data has become a requirement in many business scenarios. As a tool for automatically obtaining network information, crawlers are widely used in data collection, search engines, public opinion analysis and other fields. This article will introduce a concurrency and multi-threading processing technique for a PHP-based crawler class, and illustrate its implementation through code examples. 1. The basic structure of the reptile class is used to realize the concurrency and multi-threading of the reptile class.
