- Golang framework automated testing common problems and solutions
- Common problem: Test granularity is too large: break the test into smaller units. Testing is slow: Use parallel testing and data-driven testing. Test instability: use mocks and test fixtures to isolate tests. Insufficient test coverage: Use code coverage tools and mutate testing.

- Experience sharing on building real-time systems using Golang microservice framework
- There are five key elements when using the Golang microservices framework to build real-time systems: Choose an appropriate microservices framework, such as Gin, Echo or GoKit. Follow design principles including non-blocking, parallel processing, efficient data structures, and fault tolerance. Use Golang's concurrency features to process events in parallel. Use Gin to build real-time alerting systems that enable non-blocking, parallel processing, efficient data structures, and fault tolerance. By following these principles, you can build robust, high-performance real-time systems that meet modern business needs.

- How to use Golang to implement the retry mechanism of HTTP file upload?
- Use Go to implement the HTTP file upload retry mechanism: use the Client.Do() method to send a request. Waits for the specified number of seconds (retryWaitSeconds) when an error occurs. Retry maxRetries times at most. If the maximum number of retries is reached, the error "maximumretriesexceeded" is returned.

- How to validate JSON with regular expression in Golang?
- How to validate JSON using regular expressions in Go? Define a regular expression pattern that ensures that the string begins with curly braces, contains key-value pairs, the keys are enclosed in quotes, and the values can be strings, arrays, or nested objects. Compile regular expressions using the regular expression package. Checks whether a JSON string matches a regular expression pattern.

- Golang framework performance comparison: What factors affect the difference?
- The influencing factors of Go framework performance comparison are: Language characteristics: Go’s high concurrency characteristics affect framework performance. Framework architecture: The efficiency of the framework in processing requests and data determines performance. Dependencies: Third-party dependencies can impact performance. Deployment method: How Docker or Kubernetes is deployed affects performance. Benchmark test results show that Fasthttp has the fastest response time, Gin balances response time and throughput, and Echo has the slowest response time but has more functions. Custom router performance indicates that the framework's underlying request handling implementation is different. Optimization techniques include using coroutines to improve concurrency, choosing appropriate dependencies, optimizing database queries, and adjusting framework configurations.

- Golang framework common problems and solutions
- Common Go framework problems and their solutions include: Controller cannot be injected: Make sure the controller is registered in the main function. Model cannot be injected: Make sure the model is registered in the main function. Route registration failed: Check the uniqueness of the routing path and the correctness of the configuration. Database connection failed: Check the correctness of the database connection string or server operation. Static files cannot be accessed: Check the correctness of the file path and file configuration.

- How to handle empty file names in Golang file upload?
- For empty file names in Go file uploads, the following steps need to be taken: Check whether the FormFile object exists, and return an error if it is empty. Create a custom parser to check whether the uploaded file name is empty, and return an error if it is empty.

- How to manage concurrency using pipelines in Go?
- Pipes are a lightweight communication mechanism that allows values to be sent and received between concurrent goroutines, improving concurrency and scalability. How the pipeline works: The pipeline is a FIFO queue, consisting of a sending end (created using chan) and a receiving end, respectively.

- Security considerations for golang framework extensions
- Go framework extensions need to consider the following security considerations: Validate user input to prevent forgery. Defend against cross-site request forgery (CSRF) attacks by validating CSRF tokens. Filter sensitive data to prevent accidental disclosure. Continuously monitor applications and middleware to detect suspicious activity.

- Things to note when Golang functions receive map parameters
- When passing a map to a function in Go, a copy will be created by default, and modifications to the copy will not affect the original map. If you need to modify the original map, you can pass it through a pointer. Empty maps need to be handled with care, because they are technically nil pointers, and passing an empty map to a function that expects a non-empty map will cause an error.
