1. rabbitmq在ios中实战采坑

1.1. 问题

ios使用rabbitmq连接，没过多久就断开，并报错。且用android做相同的步骤并不会报错，错误如下

Received connection: <RMQConnection: 0x600002594080> disconnectedWithError: Error Domain=GCDAsyncSocketErrorDomain Code=7 "Socket closed by remote peer" UserInfo={NSLocalizedDescription=Socket closed by remote peer}

之后通过查看rabbitmq日志发现，日志同样也报了错误，如下

{handshake_error,starting,0,

    {error,badarg,'connection.start_ok',

        [{rabbit_framing_amqp_0_9_1,encode_method_fields,1,

             [{file,"src/rabbit_framing_amqp_0_9_1.erl"},{line,963}]},

         {rabbit_binary_generator,build_simple_method_frame,3,

             [{file,"src/rabbit_binary_generator.erl"},{line,59}]},

1.2. 解决

通过修改添加配置解决
修改rabbitmq.config

[

  {rabbit,

   [

     {tcp_listeners, [5672]},

     {heartbeat, 120},{handshake_timeout, 60000},

     {default_vhost, <<"/">>},

     {default_user, <<"user">>},

     {default_pass, <<"bitnami">>},

     {default_permissions, [<<".*">>, <<".*">>, <<".*">>]}

   ]

  },

  {rabbitmq_management,

   [

     {listener, [{port, 15672 }, {ip, "0.0.0.0"}]}

   ]

  }

].

重点是{heartbeat, 120},{handshake_timeout, 60000}，改完重启后发现正常了

1.3. 总结

handshake_timeout 表示对AMQP 0-8/0-9/0-9-1握手的最大时间(在套接字连接和SSL握手之后)，以毫秒为间隔

Default: 10000也就是10秒
事实上在ios连接rabbitmq时，这个握手时间是可能超过10s，为了避免连接断开，设置时间可以长一些
