message handler

基本解釋

Listing 1 shows a message handler that reads the request body while the request is being sent.
清單 1 顯示了一個(gè)消息處理程序，用于在發(fā)送請(qǐng)求時(shí)讀取請(qǐng)求主體。
The trouble with this approach is that your message handler is called many times to notify you of events that are not relevant for your plug-in.
這種方法的弊端是，消息處理程序?qū)⒈欢啻握{(diào)用來向您通知事件，而這些事件可能與您的插件無關(guān)。
The first step that your message handler should take is to examine the event passed in from the platform and return it immediately if it is not relevant.
因此，消息處理程序應(yīng)當(dāng)首先檢查由平臺(tái)傳入的事件，如果該事件與您的插件無關(guān)，那么立即返回此事件。
