Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those skilled in the art's every other implementation obtained without making creative work
Example, shall fall within the protection scope of the present invention.
It will be appreciated that though may be described in embodiments of the present invention using term first, second etc. each user or
Terminal, but user or terminal should not necessarily be limited by these terms.These terms are only used to for user or terminal being distinguished from each other out.For example,
In the case where not departing from range of embodiment of the invention, the first user can also be referred to as second user, similarly, second user
The first user can also be referred to as；Likewise, second user can also be referred to as third user etc., the embodiment of the present invention is to this
With no restrictions.
To understand convenient for reader, simple introduction is done to ken according to the present invention and application scenarios first:
The course of work of HTTP is typical client/server operating mode, and client is WWW browser, and server is
It is www server.The course of work of HTTP uses request/response handshake mode: 1. client connects, and both sides set up one
TCP connection；2. client issues request；3. server processing requests return to response；4. server closing connects.
The main feature of HTTP is as follows:
1) simple and quick
HTTP itself was not only simple, but also can effectively handle a large amount of requests.After client computer is connect with server, client computer must
The information that must be transmitted is requesting method and path.Exactly because HTTP is simple, so that HTTP server program small scale, and
Simply.Therefore quickly via the communication speed of HTTP, compared with other agreements, time overhead is much smaller.
2) connectionless
HTTP is a connectionless protocol.It is meant that connection only handles a request, client computer and clothes every time for limitation
It is engaged in submitting a request after device connection, be disconnected at once after client computer is connected to response.Using this connectionless protocol, do not having
When having request, server will not there the spare time wait, server more will not complete one request after also original request
It does not put.Just looking like using connectionless protocol is to write letter, once finishing writing letter sending, just it is over.Other side, which writes in reply, new information, then
Write another envelope letter.And keep connection protocol just similar with making a phone call.Both sides say by turns it is many after just hang up.In session electricity
It is occupied always to talk about line.For connectionless protocol, one side of server, which implements, to be easier, and can be made full use of online
Resource.
3) stateless
HTTP is stateless agreement: being requested each time, content, state and the performance of response are not as historical data
Remain into next stage use.It is both advantage and disadvantage.On the one hand, due to not having state, agreement does not have transaction
Memory capability.If subsequent transaction needs previous processed for information about, these information must protect outside agreement
It deposits.Lacking state means that required foregoing information must reappear, and certainly will cause to connect every time will transmit more information.Separately
On the one hand, also make HTTP burden few just because of lacking state, the speed of service is high, and server response is fast.
4) content negotiation
When server can provide multiform expression response to the request of client, need using content negotiation mechanism,
Web server is set to select the resource entity with most suitable expression-form for being able to satisfy user's requirement.Because very
It source server or the intermediate server of caching is provided does not have a unified best resource formal standard when more, and user
Browser is held also not necessarily to have the ability to handle all entity types.
5) it is easy to expand
It publishes as one using agreement, HTTP has good expandability, and what it was transmitted has been not only super
Text data.It is required on this basis for the research of application developer, exploitation, requesting method and sound can be readily added
State is answered, is run among customized system.By the server of expansion, it is able to respond the browser of original standard,
The dedicated CLIENT PROGRAM that user oneself exploitation can be distinguished makes corresponding response processing.
Http protocol development
WWW alliance set up after, organized IETF (English: Internet Engineering Task Force, Chinese: because
Special net engineering task force) group further improves and publication http protocol.So far, http protocol experienced 0.9,1.0,1.1 3
A stage.
1) HTTP/0.9 feature:
1. being used for the succinct fast protocol of various data informations；
2. having typical statelessness；
3. connectionless property；
4. not being available content negotiation；
5. picture can not be shown and be handled.
2) HTTP/1.0 feature:
1. single quick；
2. statelessness；
3. connectionless property；
4. not being available content negotiation；
5. increasing metamessage: adding a block message, the i.e. information of information before key data.It enables the server to mention
For information about for transmission data.For example, which kind of type transmission object is, with which kind of written；
6. supporting the form of plurality of kinds of contents, such as picture, audio.
3) HTTP/1.1 feature:
1. duration connects: allowing to request the browser an of web page to initiate primary connection can be above and below server
Carry multiple files；
2. still statelessness, but can provide state control；
3. having newly increased resource request: increased on the basis of original GET, HEAD, POST several method OPTIONS,
PUT, DELETE and TRACE；
4. authentication: a kind of basic access authorization method of simple " challenge-response " formula.Process is first by server
Identity is issued to client and identifies request, then confirmation message is issued by client；
5. using content negotiation mechanism；
6. (Cache) mechanism of caching: by the content for the web server response that previous client requests and request is corresponding
It is stored temporarily in the memory or physical storage of machine, so that can use when handling new client's request.
3) HTTP/2.0 is introduced:
HTTP2.0, that is, hypertext transfer protocol 2.0 is Hypertext Transfer Protocol Next Generation.It is the Hypertext by IETF
Transfer Protocol Bis (httpbis) work group develops.It is first after being issued from http1.1 in 1999
It updates.HTTP2.0 carries out interoperability testing for the first time in August, 2013.The fortune for the HTTP semantic optimization that HTTP/2.0 is provided
It is defeated.
One HTTP/2.0 connection passes through a TCP connection (the application-level agreement [TCP] operated above).Client
It is TCP connection promoter.The HTTP/2.0 agreement of logical construction: framing, streams and application program mapping.Client can be sent out
It plays HTTP2.0 and negotiates upgrading, if server supports HTTP2.0 agreement, the 100OK that server just replys HTTP2.0 is true
Recognize, otherwise the 100OK confirmation of direct response HTTP1.x.Client can also directly initiate HTTP2.0 request message, server
The request of necessary response HTTP2.0.
