1. XMPP
eXtensible Messaging and Presence Protocol可擴展消息處理和現場協議,用於在2個地點之間傳遞小型的結構化數據段的協議。定義了在兩個或更多痛心屍體之間傳遞數據所採用的格式。
2. XMPP服務器
為XMPP節提供路由。
3.應用
在XMPP內部,可以找到由聯繫人組成的花名冊,可以用它們來創建定向或無向社交圖。
當聯繫人上下線時自動發送出席通知,而個人消息和公共消息時XMLPP系統的基礎應用。
有時候開發人選選擇XMPP作為底層技術。
4. XMPP內部功能塊
構建發布-訂閱服務、多人聊天、表單檢索和處理、實時數據傳輸、隱私控制、遠程過程調用。
5. XMPP節
XMPP通信的端點以節為單位來處理輸入和產生輸出。
首先有個XMPP流,然後所有工作都是在這個流上發送和接收XMPP節實現的。
XMPP流有2份XML文檔組成,通信的每個方向均有1份。這些文檔的根節點是<stream:stream>。這個stream節點的子節點由“可陸游的節以及流相關的頂級節點”構成。每個節都是一個XML元素(包括它的子節點)。
XMPP節有3種:<presence>、<message>、<iq>。
