func (*Client) IsEncrypted

func (c *Client) IsEncrypted() bool

IsEncrypted will return true if the client is connected using a TLS transport, either because it used. TLS to connect from the outset, or because it successfully used STARTTLS to promote a TCP connection to TLS.

rawInformation send a IQ request with the the payload body to the server

func (*Client) RawInformationQuery

func (c *Client) RawInformationQuery(from, to, id, iqType, requestNamespace, body string) (string, error)

RawInformationQuery sends an information query request to the server.

func (*Client) Recv

type Options

type Options struct {
	// Host specifies what host to connect to, as either "hostname" or "hostname:port"
	// If host is not specified, the  DNS SRV should be used to find the host from the domainpart of the JID.
	// Default the port to 5222.
	Host string

	// User specifies what user to authenticate to the remote server.
	User string

	// Password supplies the password to use for authentication with the remote server.
	Password string

	OAuthScope string

	// OAuthToken provides go-xmpp with the required OAuth2 token used to authenticate

	// provided to the server as the xmlns:auth attribute of the OAuth2 authentication request.
	OAuthXmlNs string

	// TLS Config
	TLSConfig *tls.Config

	// InsecureAllowUnencryptedAuth permits authentication over a TCP connection that has not been promoted to
	// TLS by STARTTLS; this could leak authentication information over the network, or permit man in the middle
	// attacks.
	InsecureAllowUnencryptedAuth bool

	// NoTLS directs go-xmpp to not use TLS initially to contact the server; instead, a plain old unencrypted
	// TCP connection should be used. (Can be combined with StartTLS to support STARTTLS-based servers.)
	NoTLS bool

	// StartTLS directs go-xmpp to STARTTLS if the server supports it; go-xmpp will automatically STARTTLS
	// if the server requires it regardless of this option.
