java實現(xiàn)即時通信的完整步驟分享
更新時間：2020年09月09日 10:57:09 作者：氵何章懷曉 。
這篇文章主要給大家介紹了關(guān)于java實現(xiàn)即時通信的完整步驟，文中通過示例代碼介紹的非常詳細，對大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價值，需要的朋友們下面隨著小編來一起學(xué)習(xí)學(xué)習(xí)吧
前言
移動社交是我們?nèi)粘Ｉ钪泻艹Ｒ姷能浖?，最近在做即時通信，我用的是環(huán)信，和大家分享一下~~
環(huán)信的API都是基于JSON的，所以在構(gòu)造HTTP請求的時候，要指定請求頭：
注意==》環(huán)信API必須攜帶token才可以訪問。
創(chuàng)建一個認證類
