Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those skilled in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Although should be appreciated that may adopt in embodiments of the present invention term first, second etc. each user or terminal are described, user or terminal should not be limited to these terms.These terms are only used for user or terminal to be distinguished from each other out.Such as, when not departing from embodiment of the present invention scope, first user also can be called as the second user, and similarly, the second user also can be called as first user; Same, the second user also can be called as the 3rd user etc., and the embodiment of the present invention does not limit this.
For ease of reader understanding, first simple introduction is done to ken involved in the present invention and application scenarios:
The course of work of HTTP is typical client/server mode of operation, and client is WWW browser, and namely server is www server.The course of work of HTTP uses request/response handshake mode: 1. client connects, and both sides set up a TCP and connect; 2. client sends request; 3. server processing requests, returns response; 4. server closing connects.
The main feature of HTTP is as follows:
1) simple and quick
HTTP itself is both simple, can effectively process a large amount of request again.After client computer is connected with server, the information that client computer must transmit is requesting method and path.Exactly because HTTP is simple, make http server program small scale, and simply.Therefore the communication speed via HTTP is very fast, and compared with other agreement, time overhead is much smaller.
2) without connecting
HTTP is a connectionless protocol.Its implication is that restriction each connection processes a request, client computer submits to one to ask after being connected with server, receives the rear horse back of response disconnect in client computer.Use this connectionless protocol, when not asking, server can not the spare time be waited there, and server more also can not put original request after completing a request.Connectionless protocol is used to just look like be write letter, once finish writing letter to send just that it is over.The other side writes in reply fresh information, then writes another envelope letter.And keep connection protocol just similar with making a phone call.Both sides take turns to say many after just hang up.Always occupied at session telephone wire.For connectionless protocol, server one side implements than being easier to, and can make full use of online resource again.
3) stateless
HTTP is stateless agreement: ask each time, and the content of response, state and performance do not remain into next stage as historical data and use.It is advantage is also shortcoming.On the one hand, owing to not having state, agreement does not have memory capability to transaction.If follow-up transaction needs previous processed for information about, so these information must be preserved outside agreement.Lack state and mean that required foregoing information must reappear, each connection certainly will be caused will to transmit more information.On the other hand, also make HTTP burden few just because of lacking state, the speed of service is high, and server acknowledge is fast.
4) content negotiation
When server can provide multiform expression to reply to the request of client, need to use content negotiation mechanism, Web server can be selected can meet the resource entity with the most applicable expression-form that user requires.Because many times source server or provide the intermediate server of buffer memory not have a unified best resource formal standard, and user side browser is also not necessarily had the ability all entity type of process.
5) be easy to expand
Publish use agreement as one, HTTP has good expandability, and what its transmitted is not only hypertext data.On this basis for research, the development requires of application developer, requesting method and responsive state can be increased easily, among the system running on customization.Through the server expanded, the browser of original standard can be responded, also can distinguish the special CLIENT PROGRAM of user oneself exploitation, make and respond process accordingly.
Http protocol develops
After WWW alliance sets up, IETF (English: InternetEngineeringTaskForce, Chinese: internet engineering task group) group has been organized to improve further and issue http protocol.So far, http protocol experienced by 0.9,1.0,1.1 three phases.
1) HTTP/0.9 feature:
1. for the succinct fast protocol of various data message;
2. there is typical Stateless;
3. without connectivity;
4. content negotiation cannot be used;
5. cannot show and process picture.
2) HTTP/1.0 feature:
1. fast single;
2. Stateless;
3. without connectivity;
4. content negotiation cannot be used;
5. metamessage is added: before key data, add a block message, i.e. the information of information.It enables server provide and transmits data for information about.Such as, which kind of type transmission object is, be with which kind of written etc.;
6. the form of plurality of kinds of contents is supported, as picture, audio frequency etc.
3) HTTP/1.1 feature:
1. persist connection: the browser of a permission request web page initiates once to connect just to download multiple file from server;
2. still Stateless, but state can be provided to control;
3. resource request has been newly increased: on the basis of original GET, HEAD, POST several method, add OPTIONS, PUT, DELETE and TRACE;
4. authentication: a kind of basic access authorization method of simple " challenge-response " formula.Process first sends identity verify request by server to client, then sends confirmation by client;
5. content negotiation mechanism is used;
6. buffer memory (Cache) mechanism: in the internal memory that the content of web server response corresponding to previous client request and request is temporarily kept at machine or physical storage, make can utilize when processing new client and asking.
3) HTTP/2.0 introduces:
HTTP2.0 and HTML (Hypertext Markup Language) 2.0 are Hypertext Transfer Protocol Next Generations.Developed by the HypertextTransferProtocolBis of IETF (httpbis) work group.It is the first renewal after http1.1 in 1999 issues.HTTP2.0 carries out interoperability testing first in August, 2013.The transport of the HTTP semantic optimization that HTTP/2.0 provides.
A HTTP/2.0 connects and connects (the application-level agreement [TCP] run) above by a TCP.Client is TCP Connection initiator.The HTTP/2.0 agreement of logical construction: framing, streams, and application program maps.Client can be initiated HTTP2.0 and consult upgrading, if server supports HTTP2.0 agreement, the 100OK that server just replys HTTP2.0 confirms, otherwise the 100OK directly replying HTTP1.x confirms.Client also can directly initiate HTTP2.0 request message, and server must reply the request of HTTP2.0.
