使用 Go 進行 HTTP 流量重放測試
在 Web 安全測試、API 調試、流量回歸測試中，HTTP 流量重放（HTTP Traffic Replay）是一項重要的技術。它可以幫助我們復現問題、測試系統兼容性、進行安全研究等。在這篇文章中，我們將簡單探討 HTTP 流量重放的原理，並通過 Go 語言實現不同的流量重放方案，同時介紹常見的開源工具。（身爲一個在小公司裏的網安牛馬，總得幹些雜活🐂🐎）HTTP 流量重放的原理HTTP 流量重放 ⌘ Read more

Go：終於有了處理未定義字段的實用方案
衆所周知，Go 裏沒有 undefined，只有各類型的零值。多年來，Go 開發者一直依賴 JSON 結構標籤 omitempty 來解決 “字段可能缺失” 這一需求。然而omitempty 並不能覆蓋所有場景，而且常常讓人抓狂——到底什麼算 “空”？定義本就含糊不清。在 編碼（marshal） 時：切片和 map 只有在爲 nil 或長度爲 0 時纔算空。 指針只有 nil 時爲空。 ⌘ Read more

I had Chick-fil-A breakfast today (sausage, egg, and cheese biscuit, hash browns, coffee, and orange juice). Then at lunch my work place offered hot dogs. I had two (kosher, if that matters), plus a coke, a macadamia nuts cookie, and a small chocolate brownie.

So, here I am, at home, feeling hungry but guilty and refusing to eat anything else for the rest of the day. To top it off, I have only clocked 4,000 steps today (and I don’t feel like walking). I am going to hell, am I?

在 Go ORM 開篇中我們將 Go ORM 框架分成了三類🌲 反射型主要通過反射機制將結構體映射到數據庫表上，代表作爲 go-gorm/gorm🌲 代碼生成型通過代碼生成工具預先生成數據模型及查詢構建器，代表作有 ent/ent 和日益流行的 go-gorm/gen🌲 SQL 增強型基於原生 SQL 庫進行封裝和擴展，既保留 SQL 的靈活性，又提供了一系列便捷函數，代表作爲 jmoiron/s ⌘ Read more

Go 語言錯誤處理：Panic 與 Error 的抉擇
在 Go 語言的開發實踐中，錯誤處理機制是構建健壯應用程序的核心要素。與其他語言不同，Go 通過顯式的錯誤返回和獨特的 panic/recover 機制形成了獨特的錯誤處理哲學。本文將深入探討 panic 與 error 的本質區別，並通過實際場景分析幫助開發者做出正確的技術選擇。 錯誤處理機制的核心差異———–Error 的顯式傳遞特性Go 語言將 error 定義爲內置接口類型， ⌘ Read more

Go 1-25：工具鏈優化與運行時改進
Go 語言自誕生以來，始終保持着穩定的迭代節奏。2025 年 8 月即將發佈的 Go 1.25 版本在工具鏈、運行時、編譯器及標準庫等方面都帶來了值得關注的改進。本文將從實際開發角度出發，詳細解析這些變化的技術細節及其對開發者產生的實際影響。工具鏈增強—–構建系統優化go build命令的-asan選項在 1.25 版本中默認啓用了內存泄漏檢測機制。該功能會在程序退出時自動檢查未釋放的 C ⌘ Read more

** Late March Snow **
The forecast predicted snow, but even with that knowledge I held out hope that it wouldn’t. The shade over the window in the bedroom doesn’t close all the way. It always stops short of totally covering the window with about an inch further to go. It is too short. When I woke up this morning there was a flat grey line of light streaming into the room through the gap left by the too short shade. So, I spent some time shoveling this morning. Probably sooner than I ought to have since it’s still coming down. It’s 80ish de … ⌘ Read more

Ehhh yeah, what could go wrong 🤔 😵‍💫

Go 語言中 Redis 管道的性能潛力
在現代分佈式系統架構中，Redis 憑藉其卓越的性能表現已成爲不可或缺的緩存和數據存儲組件。但在高併發場景下，如何突破網絡 I/O 瓶頸成爲開發者面臨的重要挑戰。本文將深入探討 Go 語言中 Redis 管道的實現原理，並通過詳實的代碼示例展示其性能優化之道。Redis 交互模式的演進之路—————傳統 Redis 客戶端的工作模式遵循 “請求 - 響應” 的同步範式。當執行S ⌘ Read more
