用户注册

注册流程：

1、客户端进行握手给服务端发送连接消息：

[html] view plain copy

<stream:stream to="192.168.2.104" xmlns="jabber:client" xmlns:stream="http://etherx.jabber.org/streams" version="1.0"></stream:stream>

2、服务端回执：

[html] view plain copy

<?xml version=‘1.0‘ encoding=‘UTF-8‘?><stream:stream xmlns:stream="http://etherx.jabber.org/streams" xmlns="jabber:client" from="hytest240" id="9fd61155" xml:lang="en" version="1.0">
<stream:features>
<mechanisms xmlns="urn:ietf:params:xml:ns:xmpp-sasl">
<mechanism>DIGEST-MD5</mechanism>
<mechanism>JIVE-SHAREDSECRET</mechanism>
<mechanism>PLAIN</mechanism>
<mechanism>ANONYMOUS</mechanism>
<mechanism>CRAM-MD5</mechanism>
</mechanisms>
<compression xmlns="http://jabber.org/features/compress">
<method>zlib</method>
</compression><auth xmlns="http://jabber.org/features/iq-auth"/>
<register xmlns="http://jabber.org/features/iq-register"/>
</stream:features>

3、客户端发送注册申请

[html] view plain copy

<iq id="69Bxy-0" to="hytest240" type="get">
<query xmlns="jabber:iq:register"></query>
</iq>

4、服务端给出注册需要的填写的信息，相当与给客户端发送一个申请单

[html] view plain copy

<iq type="result" id="69Bxy-0" from="hytest240">
<query xmlns="jabber:iq:register">
<username/><password/><email/><name/>
<x xmlns="jabber:x:data" type="form">
<title>XMPP Client Registration</title>
<instructions>Please provide the following information</instructions>
<field var="FORM_TYPE" type="hidden">
<value>jabber:iq:register</value>
</field>
<field var="username" type="text-single" label="Username">
<required/></field>
<field var="name" type="text-single" label="Full name"/>
<field var="email" type="text-single" label="Email"/>
<field var="password" type="text-private" label="Password">
<required/>
</field>
</x>
</query>
</iq>

5、客户端接收到服务端发送的申请单后，并填写回复：

[html] view plain copy

<iq id="69Bxy-1" to="hytest240" type="set">
<query xmlns="jabber:iq:register">
<username>test</username>
<email></email>
<name></name>
<password>123456</password>
</query>
</iq>

6、注册完成后，服务端返回成功这里没有做出任何消息，仅仅只是回复。

[html] view plain copy

<iq type="result" id="69Bxy-1" from="hytest240" to="hytest240/9fd61155"/>

IQRegisterHandler

IQRegisterHandler位于org.jivesoftware.openfire.handler中。该类主要处理客户端注册信息。

该类中有两个比较重要方法initialize、handleIQ。接下来看这两个方法。

initialize

该方法主要是做初始化注册模板。这个注册模板就是在上面提到的需要发送给客户端申请注册的深表表单。源码如下：

[java] view plain copy

@Override
public void initialize(XMPPServer server) {
super.initialize(server);
userManager = server.getUserManager();
rosterManager = server.getRosterManager();
if (probeResult == null) {
// Create the basic element of the probeResult which contains the basic registration
// information (e.g. username, passoword and email)
probeResult = DocumentHelper.createElement(QName.get("query", "jabber:iq:register"));
probeResult.addElement("username");
probeResult.addElement("password");
probeResult.addElement("email");
probeResult.addElement("name");
// Create the registration form to include in the probeResult. The form will include
// the basic information plus name and visibility of name and email.
// TODO Future versions could allow plugin modules to add new fields to the form
final DataForm registrationForm = new DataForm(DataForm.Type.form);
registrationForm.setTitle("XMPP Client Registration");
registrationForm.addInstruction("Please provide the following information");
final FormField fieldForm = registrationForm.addField();
fieldForm.setVariable("FORM_TYPE");
fieldForm.setType(FormField.Type.hidden);
fieldForm.addValue("jabber:iq:register");
final FormField fieldUser = registrationForm.addField();
fieldUser.setVariable("username");
fieldUser.setType(FormField.Type.text_single);
fieldUser.setLabel("Username");
fieldUser.setRequired(true);
final FormField fieldName = registrationForm.addField();
fieldName.setVariable("name");
fieldName.setType(FormField.Type.text_single);
fieldName.setLabel("Full name");
if (UserManager.getUserProvider().isNameRequired()) {
fieldName.setRequired(true);
}
final FormField fieldMail = registrationForm.addField();
fieldMail.setVariable("email");
fieldMail.setType(FormField.Type.text_single);
fieldMail.setLabel("Email");
if (UserManager.getUserProvider().isEmailRequired()) {
fieldMail.setRequired(true);
}
final FormField fieldPwd = registrationForm.addField();
fieldPwd.setVariable("password");
fieldPwd.setType(FormField.Type.text_private);
fieldPwd.setLabel("Password");
fieldPwd.setRequired(true);
// Add the registration form to the probe result.
probeResult.add(registrationForm.getElement());
}
// See if in-band registration should be enabled (default is true).
registrationEnabled = JiveGlobals.getBooleanProperty("register.inband", true);
// See if users can change their passwords (default is true).
canChangePassword = JiveGlobals.getBooleanProperty("register.password", true);
}
