Unified error handling is implemented through middleware and the ErrorResponse structure, capturing panics and standardizing responses. The middleware uses defer and recover to prevent crashes, and the writeError function simplifies error returns, ensuring consistent and maintainable API error responses when integrated with routing. In Go language development for web services, unified error handling is key … Read more
Abandoning fasthttp Client: A Case Study Recently, I developed a web service with strict latency requirements that needed to call external HTTPS services. The maximum allowed latency was 50ms, with a maximum QPS of about 1000 (the deployed machine was configured with 4 CPU cores, 8GB of memory, and an outbound bandwidth of 12Mbps). Since … Read more
Scheduler Fairness and Real-Time Performance: Golang vs Erlang Overview This codebase contains a comparative analysis of scheduling fairness and real-time performance between Golang and Erlang. Tests indicate that the performance of Golang’s goroutine scheduler is subpar — it is coarse, unfair, and lacks good real-time capabilities. In contrast, Erlang’s scheduler excels in both fairness and … Read more
This article provides a detailed introduction to implementing an HTTP proxy using Golang. Those who have a need in practical applications can learn from it! A proxy is an important function in networking, serving to retrieve network information on behalf of network users. Figuratively speaking, it acts as a transfer station for network information. For … Read more

Introduction Today, while using the http package in GoLang, I found that the case of the headers I set did not match what I passed in. Standards The HTTP standard states that HTTP headers are case insensitive. GoLang HTTP GoLang normalizes headers when setting them, capitalizing the first letter and the first letter after a … Read more
