golang 每日一庫之 go-workflow
go-workflow 是一個基於 Go 語言開發的超輕量級工作流引擎,設計靈感來源於 Java 的 Activiti,但進行了深度簡化和解耦,特別適用於微服務架構下的流程控制需求。特點微服務架構友好 :go-workflow 僅關注流程流轉邏輯,完全解耦用戶、組織等業務數據,便於與各類系統集成。 JSON 流程定義 :採用 JSON 數組替代傳統的 BPMN 模 ⌘ Read more

如何理解高可用架構設計原理
在分佈式系統中最重要的抽象概念之一是共識, 即在網絡、進程故障等情況下, 讓所有非故障節點在某一件事情上達成一致. 那麼在實現共識的過程中, 我們就需要在理論與實踐中去發現哪些可行, 哪些不可行. 對此我們需要了解什麼是分佈式一致性, 它和我們構建一個高可用系統架構有什麼關聯? 同樣今天來談談自己的思考. 高可用原理本質 一談到高可用架構設計, 想必我們都會想到採用 “冗餘” 來實現高可用. ⌘ Read more

MCP 最新企業級權限認證方案,STDIO-SSE 不同實現詳解!
在做 MCP 企業級方案落地時, 我們可能不想讓沒有權限的人訪問 MCP Server, 或者需要根據不同的用戶返回不同的數據, 這裏就涉及到 MCP Server 授權操作。那 MCP Server 有 2 種傳輸方式, 實現起來不一樣:STDIO—–這種方式在本地運行, 它 將 MCP Server 作爲子進程啓動。 我們稱爲標準輸入輸出, 其實就是利用運行命令的方式寫入和讀取控制檯的信 ⌘ Read more

golang 開發 OA 系統,工作流引擎選型
我想開發一套企業內部使用 OA 系統,使用 golang gin 開發,讓 AI 推薦了幾個流程管理的庫,即工作流引擎。發現大部分找到的都是 Java Sprint Boot 的實現,但是我還是希望用 golang gin 去實現。畢竟 golang gin 目前用的最順手,也積累了大量的內部功能庫,而且服務器資源佔用低。加上是集團內幾個公司一塊使用,使用現成的開源實現,也達不到要求,估計也很難改 ⌘ Read more
