支付寶證書原理和使用 Golang 集成
支付寶證書驗證機制是保障交易安全的核心環節，主要是基於 PKI（公鑰基礎設施）體系構建。其驗證流程包含以下幾個關鍵部分：1，證書體系支付寶使用兩套證書，應用證書和支付寶根證書。應用證書由開發者上傳到支付寶開放平臺，支付寶根證書用於驗證支付寶返回數據的真實性。2，簽名驗證流程請求時，開發者使用私鑰對請求參數簽名，支付寶使用應用公鑰驗證。響應時，支付寶使用私鑰對返回數據簽名，開發者使用支付寶公鑰驗證。 ⌘ Read more

一文掌握常見的限流算法：計數器、漏桶、令牌桶等
限流（Rate Limiting），也稱流量控制。是指系統在面臨高併發，或者大流量請求的情況下，限制新的請求對系統的訪問，從而保證系統的穩定性。限流會導致部分用戶請求處理不及時或者被拒，這就影響了用戶體驗。所以一般需要在系統穩定和用戶體驗之間平衡一下。常見的限流算法包括固定窗口計數器算法、滑動窗口計數器算法、漏桶算法、令牌桶算法、基於用戶的限流和動態限流。其中固定窗口計數器算法、滑動窗口計數器算法 ⌘ Read more

Golang 接口加鎖與數據庫事務的重要性：從紅包漏洞看系統安全
在分佈式系統和高併發場景中，接口加鎖和數據庫事務處理是保障數據一致性和系統安全的關鍵機制。本文將通過一個真實的紅包系統漏洞案例，探討 Golang 中接口加鎖的實現方式、數據庫事務的正確使用方法，以及忽視這些機制可能帶來的嚴重後果。一、Golang 接口加鎖機制爲什麼需要接口加鎖？在高併發場景下，多個請求可能同時訪問通過一個資源（如用戶賬戶餘額），如果沒有適當的鎖機制，會導致競態條件，造成數據不一 ⌘ Read more
