關(guān)于環(huán)信3.xSDK日志簡單分析

個人博客：【lzan13 / 關(guān)于環(huán)信3.xSDK日志簡單分析
】

前言

首先說下環(huán)信日志保存的機制袱箱，這邊只要是在開啟了SDK的Debug模式下調(diào)用環(huán)信的EMLog.d()方法輸出的日志荐类，日志內(nèi)容都會在控制臺輸出的同時記錄到設備的日志文件中未状；

這里就一些常見的日志跟大家略微解釋下呈宇，一邊能給大家在以后排查問題中起到一些幫助；

PS：這里所列出來的日志內(nèi)容只是特定情況測試下出現(xiàn)胯盯，在不同的設備孟辑，不同環(huán)境下稍微會有些出入扩淀，不過一些關(guān)鍵詞的地方都應該是一樣的楔敌，不要死心眼就好；

網(wǎng)絡相關(guān)

SDK 的初始化

SDK 初始化的時候會首先檢查 DNS 配置信息是否存在驻谆，如果不存在梁丘，在初始化時會首先請求 DNS 配置列表，請求成功后就會返回一個json串旺韭，2.x 是xml格式內(nèi)容氛谜；如果當對方的網(wǎng)絡情況有問題的時候，這一步就可以看出一些問題区端，比如請求 dns 列表失敗等

關(guān)鍵詞：getDnsListFromServer,parseDnsServer,dns_time

手動登錄

當進行手動登錄是值漫，會首先獲取 DNS 配置，（上邊初始化時不是已經(jīng)獲取了么织盼，為什么還要獲妊詈巍？因為 sdk 就這樣寫的沥邻，所以它又獲取了一次??）如果不存在就去獲取危虱，獲取失敗的情況下會進行多次嘗試，然后獲取完成 DNS 之后就開始登錄了唐全，登錄要做的就是獲取賬戶的 token埃跷，后續(xù)的操作都是根據(jù)這個 token 進行操作了

自動登錄

在3.x中確定自動登錄只需要一個關(guān)鍵詞就好：autoLogin
需要注意一點，自動登錄和重連不一樣邮利，自動登錄包含初始化以及 DNS 的檢測弥雹，重連一般不檢測 DNS，自動登錄最后輸出的日志基本和重連的一樣延届，都是進行網(wǎng)絡鏈接剪勿；

鏈接監(jiān)聽與重連

連接監(jiān)聽主要是實現(xiàn) EMConnectionListener 接口來監(jiān)聽設備和服務器的連接情況运悲，其中牽扯到網(wǎng)絡恢復后與服務器的重連，下邊這部分日志是當檢測到網(wǎng)絡連接斷開后髓窜，SDK和服務器的連接情況扇苞，下邊的日志中當SDK 檢測到鏈接不到服務器后會首先清空 socket 等一些鏈接相關(guān)信息欺殿，然后會回到鏈接監(jiān)聽的onDisConnect()方法寄纵，接著 SDK 會進行嘗試重連 3 次，當嘗試全部失敗后就不在嘗試脖苏，會安排一個定時器程拭，定時器的時間是2'45"，到時間后會觸發(fā)心跳重新進行嘗試連接服務器棍潘，如果在這個心跳觸發(fā)之前恃鞋，網(wǎng)絡狀況有新的變化會直接重新嘗試連接服務器；

被踢&強制下線&移除賬戶

和賬戶相關(guān)的操作其實也都是以消息的形式和服務器進行交互的亦歉，其中一個特殊屬性為ns恤浪，類型是STATISTIC，然后具體的操作通過 operation進行細分：1.表示移除/禁用/強制下線肴楷，2.表示異地登錄
這幾個狀態(tài)都會觸發(fā)網(wǎng)絡鏈接監(jiān)聽的斷開onDisconnect()回調(diào)水由；

PS：需要注意的一點就是，當收到這幾個狀態(tài)的回調(diào)后需要手動調(diào)用logout赛蔫，清除當前登錄狀態(tài)砂客，因此在遇到被踢和強制下線的日志中一般都能看到和 logout 相關(guān)日志

消息相關(guān)

消息相關(guān)的日志還是比較明確的，

發(fā)送消息

發(fā)送新消息時會首先生成一個臨時的 msgId宝磨，這個 msgId 是當前時間戳+四位拼成弧关；當消息發(fā)送成功后盅安，服務器會返回對應的服務器生成的 msgId 然后更新到本地，這算是一個消息的發(fā)送完成（可以根據(jù)這部分來判斷消息是否發(fā)送成功）世囊；
然后如果開啟了已讀回執(zhí)别瞭，當對方讀了消息之后，發(fā)送者會收到一條通知（NOYICE 的消息）告訴你有因消息株憾，因為 ack 也是新消息蝙寨，所以也是需要自己去服務器同步拉取（注意日志中的 REAF_ACK）嗤瞎；當做完這些之后墙歪，SDK 會重新發(fā)一條同步的消息，來看下是否還有新的消息

收到新消息

3.x收到新消息后服務器并不會直接下發(fā)消息虹菲，而是給SDK端下發(fā)一個通知（NOTICE 的消息），告訴你有新消息掉瞳，就像下邊日志的第一行毕源，sdk 收到這條消息之后，會給服務器發(fā)送一個我要獲取新消息的消息（有點繞）陕习，然后服務器才會把這條消息給下發(fā)霎褐，當接收完這次通知的消息后，SDK 還會給服務器在發(fā)送一條同步消息该镣，用來詢問服務器是否還有新的消息冻璃，當返回結(jié)果包含is_last:true時，表示已經(jīng)沒有新消息拌牲；
當消息接收完成之后就是SDK內(nèi)部給上層發(fā)送通知了俱饿；最后就是當自己看了新消息之后，還要給對方發(fā)送一條ACK 的信息塌忽，然后還要收到一條服務器返回的一條狀態(tài)信息才算完事拍埠；

業(yè)務邏輯相關(guān)

在3.x 中一切的操作都是用消息的形式來做的土居，通過發(fā)送代表特定操作的消息給服務器枣购，然后服務器會返回這個消息發(fā)送成功，接著服務器會以新消息的形式告訴 SDK 操作成功擦耀，最后都和收發(fā)消息的日志邏輯一樣棉圈；
需要注意的就是這些操作中的關(guān)鍵詞；
首先說一點就是眷蜓，這些操作都有一個特殊的屬性 ns這個屬性的指表示不同的操作:MUC表示群組和聊天室相關(guān)操作分瘾；ROSTER表示聯(lián)系人相關(guān)操作

下邊先用創(chuàng)建新群組來詳細解釋下：

創(chuàng)建新群組

從創(chuàng)建群組可以看出，創(chuàng)建的操作就是給服務器發(fā)送一個創(chuàng)建的操作吁系，接著服務器返回這條消息發(fā)送成功德召，然后就像收到消息一樣白魂，服務器告訴創(chuàng)建者，你有新消息需要拉取上岗，拉取到后可以發(fā)現(xiàn)福荸，這條消息就是告訴自己群組創(chuàng)建成功，然后后邊就是檢查是否有新消息;

通話相關(guān)

由于通話功能大部分都是由底層實現(xiàn)，這邊暫時無法看懂怨规，也就先不寫了

結(jié)束語

沒有什么能一眼看出錯誤的方法，只要記住正常的日志是什么樣的幸缕，以后只要遇到錯誤的日志就知道這不正常了，所有能通過日志看出來問題的問題，都不是說一下根據(jù)哪一點日志就能知道的，一般都是需要聯(lián)系下上下文的日志谒养，然后結(jié)合場景才好分析

沒什么投機取巧的方式挺狰，其實都是熟能生巧明郭，然后大家互相交流，分享自己所知道的

最后希望這一篇分析能對大家有所幫助丰泊，
