- How to generate temporary files in Golang?
- To generate temporary files in Go, you can use two functions of the os package: TempFile and TempDir. TempFile creates a temporary file with a specified extension, example: os.TempFile("","example.txt"); TempDir returns the absolute path to the temporary directory, which can be used to create temporary files, example: os.Create(filepath.Join(os .TempDir(),"example.txt")). The system will automatically delete temporary files, which should be closed and deleted after use to release resources.

- How does the golang framework architecture achieve modularity and scalability?
- Through modularity and extensibility, the Go framework architecture promotes flexibility and makes it easy to add new features based on changing application needs. Modularization: Divide the framework into independent modules, each module is dedicated to specific functions, following the single responsibility principle, loose coupling and high cohesion. Extensibility: Allow the framework to seamlessly support new functionality and features by creating abstraction layers, implementing a plug-in system, and providing extensible configurations.

- Differences in language features between Golang and Scala
- The difference in language features between Go and Scala is: Type system: Go uses a static type system, while Scala uses a mixed type system. Concurrency: Go is based on lightweight goroutines, while Scala uses an Akka-based actor model. Generics: Go offers experimental generics features, while Scala has a mature generics system. Functional programming: Scala is influenced by functional programming and supports pattern matching and higher-order functions, while Go only supports some functional programming concepts. Ecosystem: The Go ecosystem is huge, while Scala is relatively small.

- Concurrency patterns in Go: CSP and message passing
- When programming concurrently in Go, it is crucial to understand and use appropriate patterns. CSP is a concurrency mode based on sequential processes, implemented using Goroutine, and is suitable for simple communication. Message passing is a pattern that uses channels as message queues for communication, and is suitable for complex or multiple Goroutine interaction scenarios. In practical applications, CSP can be used to implement simple message services, sending and receiving messages between different Goroutines through channels.

- Integration of golang framework and cloud platform
- The Go framework can simplify the development process by integrating with cloud platforms. Common Go frameworks include: Gin (high-performance HTTP), Echo (modern HTTP), Fiber (fast HTTP), GORM (ORM) and GoKit (microservices). Practical integration example: Use the Echo framework to integrate with GCP to implement file upload, and use the Gin framework to integrate with AWS to implement file download.

- Golang framework extension implementation principle
- The Go framework can be extended in two ways: Extension points: The framework provides predefined extension points that allow the insertion of custom code such as middleware, handlers, and validators. Code Generation: Use code generation tools to generate code that extends the functionality of the framework, allowing the creation of custom extensions without the need for manual coding.

- Golang framework performance comparison: How to benchmark framework performance?
- According to the provided article, the steps for benchmarking Go framework performance are as follows: Determine the performance metrics: request throughput, response time, or resource usage. Choose a benchmarking tool: a testing package or a third-party library such as benchmark. Write benchmark code: use the Benchmark prefix and reflect real scenarios. Set up the environment: Make sure the system configuration for testing is consistent with the production environment. Run the benchmark: Use gotest-benchmem or gotest-bench command. Analyze results: Compare the performance of different frameworks and make decisions based on benchmark results.

-
- Which golang framework is most suitable for deployment on cloud platforms?
- In cloud platforms, choosing the right Go framework is crucial. Gin is lightweight and efficient, suitable for small and medium-sized APIs and microservices; Echo is high-performance and easy to expand, suitable for large APIs and distributed systems; Beego is cross-platform and easy to use, suitable for rapid development and prototyping. Use Gin to deploy RESTfulAPI, Echo to deploy GraphQLAPI, and Beego to quickly build web applications.
