Abstract

Method to transport HTTP over XMPP, including: forming a first two-level URI template to identify web resources accessible by use of HTTP in an XMPP network, wherein a first level is XMPP-formatted and a second level is HTTP-formatted; binding HTTP to XMPP <message> and <iq> stanzas; transmitting the HTTP messages in those stanzas; receiving HTTP messages in those stanzas; and a XMPP mechanism to discover if an XMPP entity supports transporting HTTP over XMPP.

Claims

1. A system to transport HTTP over XMPP, comprising:

a computer readable storage medium, storing executable instructions; and

a processor in communication with the computer readable storage medium, the processor when executing the executable instructions;

forms a first two-level URI template to identify web resources accessible by use of HTTP in an XMPP network, wherein a first level is XMPP-formatted and a second level is HTTP-formatted;

binds HTTP to XMPP in the first two-level URI template, wherein binding HTTP to XMPP comprises;

binding HTTP GET to an XMPP <

iq type=“

get”

>

stanza;

binding HTTP PUT, POST and DELETE to an XMPP <

iq type=“

set”

>

stanza;

binding HTTP response codes 1xx-3xx to an XMPP <

iq type=“

result”

>

stanza; and

binding HTTP response codes 4xx-5xx to an XMPP <

iq type=“

error”

>

stanza;

transmits the first two-level URI template to a destination;

receives a second two-level URI template from the destination; and

dereferences the second two-level URI template.

2. The system of claim 1, wherein the destination comprises an HTTP/XMPP gateway.

3. The system of claim 1, wherein the processor, when executing the executable instructions, transmits the first two-level URI template by using an XMPP process library.

4. The system of claim 1, wherein the processor, when executing the executable instructions, dereferences the second two-level URI template by:

extracting an XMPP JID from the second two-level URI template;

assigning the XMPP JID to an HTTP Host header field;

extracting an HTTP Request-URI field from a portion of the second two-level URI template following a predetermined delimiter;

activating an XMPP connection;

transmitting an XMPP IQ stanza to a destination indicated by the JID, wherein the XMPP IQ stanza comprises an HTTP GET message to a URI location indicated by the HTTP Request-URI;

receiving a result IQ stanza from the destination indicated by the JID; and

extracting a response from the result IQ stanza.

5. The system of claim 4, wherein the processor, when executing the executable instructions, activates the XMPP connection by selecting a previously established XMPP connection.

6. The system of claim 4, wherein the processor, when executing the executable instructions, activates the XMPP connection by prompting a user to log in to an XMPP server.

7. The system of claim 1, wherein the processor, when executing the executable instructions, transmits an XMPP service discovery stanza to the destination, wherein the XMPP service discovery stanza comprises one of a query of supported protocols or a query of an entry point URI.

8. The system of claim 7, wherein the processor, when executing the executable instructions:

receives a response to the XMPP service discovery stanza; and

invokes REST services at the entry point URI.

9. A system to transport HTTP over XMPP, comprising:

a computer readable storage medium, storing executable instructions; and

a processor in communication with the computer readable storage medium, the processor when executing the executable instructions;

forms a first two-level URI template to identify web resources accessible by use of HTTP in an XMPP network, wherein a first level is XMPP-formatted and a second level is HTTP-formatted;

binds HTTP to XMPP <

message> and

<

iq>

stanzas, wherein binding HTTP to XMPP comprises;

binding HTTP GET to an XMPP <

message type=“

chat|groupchat|normal”

>

stanza;

binding HTTP PUT, POST and DELETE to an XMPP <

message type=“

chat|groupchat|normal”

>

stanza;

binding HTTP response codes 1xx-3xx to an XMPP <

message type=“

chat|groupchat|normal”

>

stanza; and

binding HTTP response codes 4xx-5xx to an XMPP <

message type=“

error”

>

stanza;

transmits the XMPP<

message> and

<

iq>

stanzas;

receives an HTTP message in received <

message> and

<

iq>

stanzas; and

discovers, by use of an XMPP mechanism, whether an XMPP entity supports the transport of HTTP over XMPP.

10. The system of claim 9, wherein the processor, when executing the executable instructions, transmits the <

message> and

<

iq>

stanzas to an HTTP/XMPP gateway.

11. The system of claim 9, wherein the processor, when executing the executable instructions, transmits the <

message> and

<

iq>

stanzas by using an XMPP process library.

12. The system of claim 9, wherein the processor, when executing the executable instructions, discovers whether an XMPP entity supports the transport of HTTP over XMPP by:

extracting an XMPP JID from a second two-level URI template;

assigning the XMPP JID to an HTTP Host header field;

extracting an HTTP Request-URI field from a portion of the second two-level URI template following a predetermined delimiter;

activating an XMPP connection;

transmitting an XMPP IQ stanza to a destination indicated by the JID, wherein the XMPP IQ stanza comprises an HTTP GET message to a URI location indicated by the HTTP Request-URI;

receiving a result IQ stanza from the destination indicated by the JID; and

extracting a response from the result IQ stanza.

13. The system of claim 12, wherein the processor, when executing the executable instructions, activates the XMPP connection by selecting a previously established XMPP connection.

14. The system of claim 12, wherein the processor, when executing the executable instructions, activates the XMPP connection by prompting a user to log in to an XMPP server.

15. The system of claim 12, wherein the processor, when executing the executable instructions, transmits an XMPP service discovery stanza to the destination, wherein the XMPP service discovery stanza comprises one of a query of supported protocols or a query of an entry point URI.
