Question

我的任务是创建一个必须与服务器上的其他客户端通信的C ++ XMPP客户端。我使用Gloox库编写了一个简单的C ++ XMPP客户端，在服务器上注册一个新用户。我使用的服务器是Openfire，IDE是VC ++ 2008.

// register_example.cpp

class RegTest : public RegistrationHandler, ConnectionListener, LogHandler

{

public:
RegTest() {}
virtual ~RegTest() {}

void start()
{
  j = new Client( "localhost" );
  j->disableRoster();
  j->registerConnectionListener( this );
  m_reg = new Registration( j );
  m_reg->registerRegistrationHandler( this );
  j->logInstance().registerLogHandler( LogLevelDebug, LogAreaAll, this );
  j->connect();
  delete( m_reg );
  delete( j );
}

virtual void onConnect()
{
 m_reg->fetchRegistrationFields();
}

virtual void onDisconnect( ConnectionError e ){ 
printf( "register_test: disconnected: %d\n", e );    }

virtual bool onTLSConnect( const CertInfo& info )
{
  printf( "status: %d\nissuer: %s\npeer: %s\nprotocol: %s\nmac: %s\ncipher: %s\ncompression: %s\n",
  info.status, info.issuer.c_str(), info.server.c_str(),
  info.protocol.c_str(), info.mac.c_str(), info.cipher.c_str(),
  info.compression.c_str() );
  return true;
}

virtual void handleRegistrationFields( const JID& /*from*/, int fields, std::string  instructions )
{
  printf( "fields: %d\ninstructions: %s\n", fields, instructions.c_str() );
  RegistrationFields vals;
  vals.username = "testuser";
  vals.password = "testpwd";
  m_reg->createAccount( fields, vals );
}

virtual void handleRegistrationResult( const JID& /*from*/, RegistrationResult result )
{
  printf( "result: %d\n", result );
  j->disconnect();
}

virtual void handleAlreadyRegistered( const JID& /*from*/ )
{
  printf( "the account already exists.\n" );
}

virtual void handleDataForm( const JID& /*from*/, const DataForm& /*form*/ )
{
  printf( "datForm received\n" );
}

virtual void handleOOB( const JID& /*from*/, const OOB& oob )
{
  printf( "OOB registration requested. %s: %s\n", oob.desc().c_str(), oob.url().c_str() );
}

virtual void handleLog( LogLevel level, LogArea area, const std::string& message )
{
  printf("log: level: %d, area: %d, %s\n", level, area, message.c_str() );
}
 private:
 Registration *m_reg;
 Client *j;
};

int _tmain(int argc, _TCHAR* argv[])
{
  RegTest *r = new RegTest();
  r->start();
  return 0;
}

代码构建成功，但是当我运行代码时，我得到以下错误代码400 ---错误请求。请告诉我出了什么问题？日志 -

Answer 1

服务器需要的信息比“jabber：iq：register”命名空间的架构支持的信息多，因此服务器向您发送了数据表单。您必须返回填充的数据表单，该表单优先于“jabber：iq：register”的字段。它在XEP-0077（带内注册）的Extensibility部分中定义。

无法将Gloox Xmpp客户端连接到Openfire服务器
