Android推送SDK(9)-TCP网络问题

心跳异常

香港心跳异常

现象

  • 手表使用香港卡用80端口连接到IM服务器出现心跳急剧下降到60秒的异

  • 出现异常的都是使用80端口,如果是使用8000端口就恢复正常

原因

  • 80端口是Http的常用端口号,连接到IM服务器之后,由于服务器并没有

把Http和TCP连接服务做区分导致IM的TCP使用80端口连接进来的时候被误

识别成是一个Http请求,所以就对IM的TCP数据流(TLV格式)进行解析导

致报错返回了一个Http请求报错的网页的Html数据,具体返回的数据格式

客户端打印是:


400 Bad Request


nginx/1.8.0

以上是客户端TCP数据流read到100字节打印出来的数据,是一个Http请求

失败返回Http状态码为400的网页Html数据

以上是tcpdump抓包信息,从抓包信息中可以得知返回的数据确实是一个

Http请求失败的网页,对比客户端程序log打印是吻合的

  • 客户端的TCP流读取到上述数据的时候以为是IM服务器正常返回的TLV格

式的数据,所以对read到的数据进行常规的TLV数据解析导致程序解析报错

(数组越界):

{ConnectionService$6.onRead--1} 
com.xtc.sync.b.b: decode data 

error:java.lang.ArrayIndexOutOfBoundsException: src.length=45 

srcPos=2 dst.length=121 dstPos=0 length=121
at com.xtc.sync.push.common.f.a(Unknown Source)
at com.xtc.sync.push.common.ConnectionService$6.onRead(Unknown 

Source)
at com.xtc.sync.push.common.m.b(Unknown Source)
at com.xtc.sync.push.common.m.a(Unknown Source)
at com.xtc.sync.push.common.m.run(Unknown Source)

客户端发生数据解析报错之后会认为当前接收到的数据已经不正确,同时

也会认为后面接续读取的数据也将不正确,所以会把socket连接关闭重连

java.net.SocketException: Socket closed
at java.net.SocketInputStream.socketRead0(Native Method)
at java.net.SocketInputStream.read(SocketInputStream.java:151)
at java.net.SocketInputStream.read(SocketInputStream.java:120)
at java.net.SocketInputStream.read(SocketInputStream.java:106)
at com.xtc.sync.push.common.m.run(Unknown Source)
  • 对于客户端IM SDK而言
  1. 遇到数据解析异常导致的TCP连接断开跟网络NAT超时时间无关,因此不

应该下调心跳周期,但是旧版(1.0.1Realease-1.0.6Realease版本)存在

不足,并没有对此做过滤处理,所以会不断的下调心跳

  1. 在遇到数据解析异常断开重连的时候没有做时间间隔递增的重连,所以

断线后会马上重连

  1. 客户端IM SDK在断线重连之前没有先切换域名或者端口,选择拿原来连

接断开的域名和端口再次尝试重连,在重试重连失败的时候才会去切换域

名或者端口,而遇到这种情况,每次尝试重连TCP都能连接成功,连接成功

之后,数据解析失败又把TCP连接断开,然后再拿原来的域名和端口,再重

连,再断开,如此陷入死循环,无法切换域名或者端口,断线重连频率很

高:

  • 具体log分析流程
  1. connect to server success,hostname:gw.im.okii.com,port:80代表

TCP连接IM服务器gw.im.okii.com成功,连接端口为80

  1. read [323] bytes,all buffer bytes:323表示客户端杜渠道服务端写

入的TCP数据为323个字节

  1. cut data[86] bytes,rest buffer bytes:237表示客户端开始对读取到

的数据进行解析

  1. java.lang.ArrayIndexOutOfBoundsException: src.length=45

srcPos=2 dst.length=121 dstPos=0 length=121表示数据解析报错,数组

越界

  1. 对与解析错误的数据做打印输出,然后关闭TCP连接进行重连:

解决方案

  • 服务器把Http和TCP服务做区分,避免对使用80端口连接进来的IM服务错

误的识别成Http短连接

  • 客户端优化心跳下调策略,在遇到数据解析错误导致的TCP断开的时候,

不下调心跳间隔,避免心跳误下调,影响心跳探测的准确性

  • 客户端优化重连策略,在遇到数据解析错误导致的断开重连的时候要做

时间间隔递增重连,避免频繁的重连

  • 客户端新程序不再允许使用80端口去连接IM服务器,不单单是80端口,

一些常用的端口,例如8080,443,1000一下的端口等都不能使用,避免出

现类似的问题

  • 客户端在每一次重连之前首先切换下域名或者端口,避免用同一个域名

和端口去再次连接IM服务器导致无法跳出这个域名和端口连接造成的异常

,如果客户端有成功切换域名或者端口,那么遇到上述情况会立即切换到

8000端口,次数连接就会恢复正常

解决效果

  • 服务器在对Http和TCP服务做了区分之后,从大数据分析来看,香港几台

有上传大数据的手表分析来看全部都恢复正常使用

  • 等待客户端的新版IM程序测试更新

青海心跳异常

现象

  • 青海心跳周期异常的现象和香港的现象一模一样

原因

  • 客户端使用80端口连接gw.im.okii.com域名的时候被运营商劫持到了

111.44.228.186这个地址(正确的应该是106.75.86.52),而被误识别成

Http短链接,然后返回一个错误的网页html数据,然后客户端接收到数据

后解析报错,导致频繁的断线重连和心跳下调

  • 客户端的心跳下调策略和重连策略存在缺陷,遇到这种情况后会导致心

跳误下调,重连频繁,与香港的原因类似

{TCPConnection.a--1} local 

dns,hostname:gw.im.okii.com,ip:111.44.228.186

gw.im.okii.com本地dns解析出来的ip为111.44.228.186,由此确认是被劫

客户端在不切换域名和端口的情况下断线重连成功

解决方案

  • 客户端禁止使用80端口
  • 针对以上香港问题分析出的客户端在心跳下调策略,重连策略存在的缺

陷进行修复(主要是在重连的时候要确保域名或者端口的切换,不要拿旧

的域名和端口再次尝试连接)

解决效果

  • 青海域名劫持问题,TCP连接80端口可以成功,但是不确定8000端口是否

能成功,如果8000端口无法连接成功,那么1.0.4Release或以上版本(去

掉80端口)程序在遇到域名被劫持的时候,再次尝试连接不成功,这时候

就会去跑常规的httpdns流程

  • 新修改的IM的Httpdns方案无论是否使用80端口,都可以解决劫持的

问题,目前并没有在1.0.+Release版本的程序更新,是在当前手表主干更

新的,目前还在提测阶段
