Course Introduction：This article discusses how to efficiently manage a PHP file so that it can be used as an API interface for front-end AJAX requests and as an internal library function for back-end PHP scripts. The core solution is to use the conditional judgment mechanism to distinguish HTTP requests from internal references, thereby avoiding unnecessary code execution and ensuring the flexibility and correctness of the script. The article will provide specific code examples and discuss related best practices.

Course Introduction：Axios Key Points Axios is a popular Promise-based HTTP client with an easy-to-use API that can be used in browsers and Node.js environments. It provides a versatile tool for JavaScript developers. Axios differs from the built-in Fetch API in several ways, including its handling of HTTP error codes, its automatic inclusion of cookies in requests, and the ability to provide upload/download progress updates. Axios allows developers to convert output or input data and add interceptors, functions that are triggered when a request is made or a response is received. These functions are for processing data and managing

Course Introduction：In Debian systems, OpenSSL is an important library for encryption, decryption and certificate management. To prevent a man-in-the-middle attack (MITM), the following measures can be taken: Use HTTPS: Ensure that all network requests use the HTTPS protocol instead of HTTP. HTTPS uses TLS (Transport Layer Security Protocol) to encrypt communication data to ensure that the data is not stolen or tampered during transmission. Verify server certificate: Manually verify the server certificate on the client to ensure it is trustworthy. The server can be manually verified through the delegate method of URLSession

Course Introduction：This article explores the challenge of how to remotely shut down an HTTP server in Go and ensure that clients can receive downtime acknowledge messages. In response to the problem that directly using os.Exit may lead to message loss, the article details how to use http.Hijacker to force the sending of responses and discusses its limitations. At the same time, the article also looks forward to more elegant server downtime strategies, including managing on-the-go requests and leveraging the modern features of the Go standard library, aiming to provide a comprehensive solution guide.

Course Introduction：Use rate.Limiter to realize the basic current limiting based on the token bucket algorithm, and block the waiting token through the Wait() method to ensure that the number of requests processed per second does not exceed the set value; 2. Use the Allow() method to check whether the request is released without blocking, which is suitable for quickly rejecting over-limit requests and returning a 429 status code; 3. The current limiter can be integrated into HTTP middleware to achieve global current limiting, and the rate of all requests is unified; 4. Use map to combine sync.RWMutex to independently maintain the current limiter for each IP or user to achieve fine-grained current limiting; it is necessary to note that long-term unused current limiter instances should be cleaned regularly in the production environment to avoid memory leakage. Go's rate package is simple and efficient, and is easy to integrate into various services.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
