Cross-platform development is no longer a problem: learn Go language
With the rapid development of the mobile Internet, cross-platform development has become the choice of more and more developers. Cross-platform development can greatly reduce development workload, improve development efficiency, and enable applications to be released on multiple platforms at the same time. As an open source programming language, Go language has become one of the preferred languages for cross-platform development with its efficient concurrency features and powerful performance advantages. This article will lead you to learn the Go language and master how to use the Go language for cross-platform development.
1. Why choose Go language?
- Concurrency Features
The Go language has built-in powerful concurrency features. Through the goroutine and channel mechanisms, developers can easily write concurrent programs. This is especially important for cross-platform development, which allows applications to run well on different platforms and make full use of the resources of each platform. - Simple syntax
The syntax of Go language is simple and easy to understand, and the learning curve is relatively gentle. It uses clear naming conventions and simple syntax structures, allowing developers to get started quickly. This is very helpful for developing and maintaining code quickly. - Powerful standard library
Go language has a rich standard library, including many commonly used functional modules, such as network programming, image processing, etc. These functional modules can greatly simplify the development process and reduce development costs.
2. Go language cross-platform development example
Below we take a simple web crawler as an example to demonstrate how to use Go language for cross-platform development.
package main import ( "fmt" "net/http" "strings" "golang.org/x/net/html" ) func main() { url := "http://example.com" //待爬取的网址 links, err := ExtractLinks(url) if err != nil { fmt.Println("Error:", err) return } fmt.Println(links) } func ExtractLinks(url string) ([]string, error) { resp, err := http.Get(url) if err != nil { return nil, err } defer resp.Body.Close() doc, err := html.Parse(resp.Body) if err != nil { return nil, err } var links []string visitNode := func(n *html.Node) { if n.Type == html.ElementNode && n.Data == "a" { for _, a := range n.Attr { if a.Key == "href" { link := a.Val if !strings.HasPrefix(link, "http") { link = url + link } links = append(links, link) } } } } preOrder(doc, visitNode) return links, nil } func preOrder(n *html.Node, f func(n *html.Node)) { if n != nil { f(n) for c := n.FirstChild; c != nil; c = c.NextSibling { preOrder(c, f) } } }
The above code implements a simple web crawler that can obtain a list of all links in the page through the specified URL. The code uses the http and html packages in the Go standard library to implement HTTP requests and HTML parsing. This code will run on any platform and get the same results.
3. Things to note when developing cross-platform Go language For APIs or libraries, try to use the Go language standard library or cross-platform library.
Pay attention to the processing of file paths. The file path representation methods on different platforms may be different and need to be adapted.
- For projects that need to be compiled into executable files, you need to use cross-compilation tools to generate executable files corresponding to the target platform.
- Summary:
- By learning Go language, we can easily carry out cross-platform development. The concurrency features, concise syntax, and rich standard library of the Go language make it an ideal choice for cross-platform development. I hope this article can help readers better master the Go language so that they can play a greater role in cross-platform development.

Golang is suitable for rapid development and concurrent programming, while C is more suitable for projects that require extreme performance and underlying control. 1) Golang's concurrency model simplifies concurrency programming through goroutine and channel. 2) C's template programming provides generic code and performance optimization. 3) Golang's garbage collection is convenient but may affect performance. C's memory management is complex but the control is fine.

C is more suitable for scenarios where direct control of hardware resources and high performance optimization is required, while Golang is more suitable for scenarios where rapid development and high concurrency processing are required. 1.C's advantage lies in its close to hardware characteristics and high optimization capabilities, which are suitable for high-performance needs such as game development. 2.Golang's advantage lies in its concise syntax and natural concurrency support, which is suitable for high concurrency service development.

Golang excels in practical applications and is known for its simplicity, efficiency and concurrency. 1) Concurrent programming is implemented through Goroutines and Channels, 2) Flexible code is written using interfaces and polymorphisms, 3) Simplify network programming with net/http packages, 4) Build efficient concurrent crawlers, 5) Debugging and optimizing through tools and best practices.

The core features of Go include garbage collection, static linking and concurrency support. 1. The concurrency model of Go language realizes efficient concurrent programming through goroutine and channel. 2. Interfaces and polymorphisms are implemented through interface methods, so that different types can be processed in a unified manner. 3. The basic usage demonstrates the efficiency of function definition and call. 4. In advanced usage, slices provide powerful functions of dynamic resizing. 5. Common errors such as race conditions can be detected and resolved through getest-race. 6. Performance optimization Reuse objects through sync.Pool to reduce garbage collection pressure.

Go language performs well in building efficient and scalable systems. Its advantages include: 1. High performance: compiled into machine code, fast running speed; 2. Concurrent programming: simplify multitasking through goroutines and channels; 3. Simplicity: concise syntax, reducing learning and maintenance costs; 4. Cross-platform: supports cross-platform compilation, easy deployment.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
