經過ejabberd的日誌，整理了下客戶端登陸流程。 html

1. 經過TCP鏈接5222端口的流程： node

(1) 客戶端向服務器發送stream流服務器

<stream:stream to="nba.com"
               xml:lang="*"
               version="1.0"
               xmlns:stream="http://etherx.jabber.org/streams"
               xmlns="jabber:client">

(2) 服務器應答stream

<?xml version='1.0'?>
<stream:stream xmlns='jabber:client'
               xmlns:stream='http://etherx.jabber.org/streams'
               id='4171758611'
               from='nba.com'
               version='1.0'
               xml:lang='en'>

(3) 服務器發送流特性

<stream:features>
	<starttls xmlns='urn:ietf:params:xml:ns:xmpp-tls'/>
	<mechanisms xmlns='urn:ietf:params:xml:ns:xmpp-sasl'>
		<mechanism>PLAIN</mechanism>
	</mechanisms>
	<c xmlns='http://jabber.org/protocol/caps'
	   hash='sha-1'
	   node='http://www.process-one.net/en/ejabberd/'
	   ver='AxFG3uvIZfHAbBjOUb9t3klmoos='/>
	<register xmlns='http://jabber.org/features/iq-register'/>
</stream:features>

(4) 客戶端發送tls請求

<starttls xmlns="urn:ietf:params:xml:ns:xmpp-tls"/>

(5) 服務器迴應並開始TLS握手

<proceed xmlns='urn:ietf:params:xml:ns:xmpp-tls'/>

(6) TLS握手完成後，客戶端從新初始化stream流

<stream:stream to="nba.com"
               xml:lang="*"
               version="1.0"
               xmlns:stream="http://etherx.jabber.org/streams"
               xmlns="jabber:client">

(7) 服務器應答

<?xml version='1.0'?>
<stream:stream xmlns='jabber:client'
               xmlns:stream='http://etherx.jabber.org/streams'
               id='703708799'
               from='nba.com'
               version='1.0'
               xml:lang='en'>

(8) 服務器告知客戶端支持的SASL驗證機制

<stream:features>
	<mechanisms xmlns='urn:ietf:params:xml:ns:xmpp-sasl'>
		<mechanism>PLAIN</mechanism>
	</mechanisms>
	<c xmlns='http://jabber.org/protocol/caps'
	   hash='sha-1'
	   node='http://www.process-one.net/en/ejabberd/'
	   ver='AxFG3uvIZfHAbBjOUb9t3klmoos='/>
	<register xmlns='http://jabber.org/features/iq-register'/>
</stream:features>

(9) 客戶端選擇簡單認證機制併發送用戶名密碼

<auth xmlns="urn:ietf:params:xml:ns:xmpp-sasl" mechanism="PLAIN">
AGNoZW53ZW5jYW4ja2VkYWNvbS5jb20AMjEyMThjY2E3NwgzNGQyYmExOTIyYzMzZTAxNTExMDU=
</auth>

(10) 服務器告訴客戶端校驗經過，SASL握手完成

<success xmlns='urn:ietf:params:xml:ns:xmpp-sasl'/>

(11) 客戶端再次初始化stream流

<stream:stream to="nba.com"
               xml:lang="*"
               version="1.0"
               xmlns:stream="http://etherx.jabber.org/streams"
               xmlns="jabber:client">

(12) 服務器應答 session

<?xml version='1.0'?>
<stream:stream xmlns='jabber:client'
               xmlns:stream='http://etherx.jabber.org/streams'
               id='2767342509'
               from='nba.com'
               version='1.0'
               xml:lang='en'>

(13) 通知客戶端進行資源綁定併發

<stream:features>
	<bind xmlns='urn:ietf:params:xml:ns:xmpp-bind'/>
	<session xmlns='urn:ietf:params:xml:ns:xmpp-session'/>
	<c xmlns='http://jabber.org/protocol/caps'
	   hash='sha-1'
	   node='http://www.process-one.net/en/ejabberd/'
	   ver='AxFG3uvIZfHAbBjOUb9t3klmoos='/>
	<register xmlns='http://jabber.org/features/iq-register'/>
</stream:features>

(14) 客戶端請求資源綁定 spa

<iq type="set" id="0">
	<bind xmlns="urn:ietf:params:xml:ns:xmpp-bind">
	<resource>boston</resource>
	</bind>
</iq>

(15) 服務器應答 .net

<iq id='0' type='result'>
	<bind xmlns='urn:ietf:params:xml:ns:xmpp-bind'>
	<jid>rondo@nba.com/boston</jid>
	</bind>
</iq>

(16) 客戶端請求session綁定 rest

<iq type="set" id="1">
	<session xmlns="urn:ietf:params:xml:ns:xmpp-session"/>
</iq>

(17) 服務器應答日誌

<iq type='result' id='1'>
	<session xmlns='urn:ietf:params:xml:ns:xmpp-session'/>
</iq>

至此，可認爲登錄完成，後續進行能力協商，發送其餘請求消息，發送出息消息等。

2. 經過http鏈接5280端口的流程 code

http方式的交互是經過BOSH協議完成的，詳細可參見

      wait='60'
      hold='1'
      content='text/xml;charset=utf-8'

    <stream:features xmlns:stream='http://etherx.jabber.org/streams'>
        <mechanisms xmlns='urn:ietf:params:xml:ns:xmpp-sasl'>
            <mechanism>PLAIN</mechanism>
        </mechanisms>
        <c xmlns='http://jabber.org/protocol/caps'
           hash='sha-1'
	   node='http://www.process-one.net/en/ejabberd/'
	   ver='AxFG3uvIZfHAbBjOUb9t3klmoos='/>
