Description
Technical field
The present invention relates to field of computer technology, more particularly to a kind of method and dress acting on behalf of HTTP request by UDP
Put.
Background technology
When a web site is accessed, domain name is sent to DNS (Domain Name System, domain name system) to go to parse, DNS solves
After analysis, IP (Internet Protocol, the agreement of interconnection between the network) address of website is returned to client, by IP ground
HTTP (Hyper Text Transfer Protocol, HTML (Hypertext Markup Language)) request is initiated in location.During HTTP request,
Connected by setting up TCP (Transmission Control Protocol, transmission control protocol), client could take to Web
Business device sends solicited message, and Web server, after receiving solicited message, returns corresponding response message, and client receives
After the response message of Web server, execution is explained to these data, Web server cuts out TCP and connects simultaneously.
But, the HTTP application based on TCP transmission agreement, connect in wireless network environment, the network of trans-regional operator
When connecing server, the three-way handshake process being typically passed through TCP could set up connection.Three-way handshake is i.e. to each data sending
Amount be how to follow the tracks of hold consultation make data segment send and receive synchronization, the data being determined according to received data volume
Confirm number and data is activation, receive after when cancel contact, and set up virtual connections.If packet loss in handshake procedure,
Connect the process meeting last for several seconds of three-way handshake, at this moment, do not connect always in terms of client application, from server end application
Never receive the request content of user, cause the situation of both-end sky etc., only lean on client setting application layer timer to sentence
Disconnected time-out, leads to request slow, efficiency is low.
And, similar DNS request is also easily by Local DNS (Local Domain Name System, home domain name
System) server kidnapped, and for example, operating system can be sent to this domain name the name server of this area, if operation
If business wants to kidnap domain name, just the name server in his this area, directly in response to a wrong IP to user, leads to
User by flow process connect further this IP failure, although or connect upper, cannot correct IP address response results.

During existing HTTP request, connected by setting up TCP, client could send request letter to Web server
Breath.Connect the substantial amounts of resource overhead of consuming due to setting up multiple TCP, so in the case of allowing and be possible, taking by agency
Business device agency forwards HTTP request.The function of proxy server is exactly that agency network user goes to obtain the network information.Figuratively：
It is the terminal of the network information.In general, directly go to connect the acquirement of other internet sites using web browser
During the network information, request signal must be sent and answered, then other side is returned information with byte mode transmission again.
Proxy server is a server between browser and Web server, and after having it, browser is not
It is directly to go to fetch webpage to Web server but sends request to proxy server, request signal can first deliver to agency service
Device, to fetch the information required for browser by proxy server and to send browser to.And, most of proxy server is all
There is the function of buffering, just look like a big cache memory, it has very big memory space, and it constantly will newly obtain
Data storage on the memorizer of its machine, if the data that browser is asked existed on the memorizer of its machine and
And be up-to-date, then it does not just fetch data from Web server again, and directly sends the data on memorizer to user
Browser, thus can significantly improve surfing and efficiency.More importantly：Proxy server is the Internet link level gateway
A kind of important security function being provided, its work is mainly in the dialogue layer of open system interconnection model.
Based on this, embodiments provide a kind of method and apparatus that HTTP request is acted on behalf of by UDP, detailed process
As follows：
Referring to Fig. 1, Fig. 1 is a kind of a kind of stream of method acting on behalf of HTTP request by UDP provided in an embodiment of the present invention
Journey schematic diagram, comprises the steps：
S101, receives the UDP request message that first network equipment sends, and UDP request message includes UDP request header, unification
Resource identifier；
Specifically, UDP proxy server receives the UDP request message that first network equipment sends, this UDP request message bag
Include UDP request header, Uniform Resource Identifier.Here, UDP request header is to be prepared to UDP agency service according to first network equipment
HTTP domain name construction in the HTTP request that device is initiated, this HTTP domain name is one of HTTP Uniform Resource Identifier in HTTP request
Part, the therefore uniform resource identifier in UDP request message do not include HTTP domain name.By what first network equipment was initiated
HTTP request, is configured to UDP request message, thus sending this UDP request to UDP proxy server, completing UDP and acting on behalf of HTTP
The process of request.
In addition, it is necessary to explanation, the first network equipment being previously mentioned in embodiments of the present invention and second network equipment,
Refer respectively to send the original sender of HTTP request and receive HTTP request recipient, for example, first network equipment is permissible
It is client, second network equipment can be server end, for meeting all-network appointed condition, belong to the present invention real
Apply the protection domain of example, here differs a citing.
S102, parses UDP request header from UDP request message, identifies HTTP domain name, and according to HTTP domain name and unification
Resource identifier constructs HTTP request message, and UDP request header is to be constructed according to HTTP domain name, the destination of HTTP request message
Location is second network equipment；
Specifically, because the UDP request header in UDP request message is by the HTTP domain name construction in first network equipment
, therefore parse this UDP request header it is possible to identify this HTTP domain name corresponding to UDP request header.Further, since UDP please
Ask and in the Uniform Resource Identifier in message, there is no HTTP domain name, therefore by the HTTP having identified domain name and unified resource mark
Know symbol jointly to construct HTTP request message, the HTTP request message constructing here is the HTTP request message of standard, meanwhile, should
The destination address of HTTP request message is second network equipment.
S103, sends HTTP request message to second network equipment.
Specifically, HTTP request message is sent to second network equipment by UDP proxy server, due to this HTTP request
Message is that therefore this HTTP request message is included by HTTP domain name and system by HTTP domain name and Uniform Resource Identifier construction
The HTTP Uniform Resource Identifier of one resource identifier composition, sends an inclusion HTTP unified resource to second network equipment
The request message of identifier, thus complete act on behalf of, by UDP, the process forwarding HTTP request.
It should be noted that in the present embodiment, disappear because a UDP request is only capable of the less request of transmitting request text
Breath, it is therefore possible to use the method agency of the present embodiment forwards the request response less HTTP request of text.For example, if one
Individual UDP bag maxsize is 1.5KB, if the request text of HTTP request is more than 1.5KB, just cannot act on behalf of clothes by UDP
Business device agency forwards this request, if http response text is more than 1.5KB, this http response text can be disassembled into several
The response text of these 1.5KB can be numbered with sequence number and be sent respectively to first network equipment by 1.5KB, UDP proxy server, the
One network is combined, and reads complete response text.
As can be seen here, a kind of method acting on behalf of HTTP request by UDP that the present invention provides, by UDP proxy server
First receive the UDP request message that first network equipment sends, then disappeared according to the HTTP request that this UDP request message constructs standard
HTTP request message is finally issued second network equipment by breath.This method that forwarding HTTP request is acted on behalf of by UDP, it is to avoid
The three-way handshake of TCP and DNS request, during effectively solving for request text less HTTP request, the three of TCP
Secondary shaking hands leads to ask the low problem of efficiency, and during HTTP request, DNS request is held as a hostage problem, improves request effect
Rate.
In embodiments of the present invention, after sending HTTP request message to second network equipment, acting on behalf of HTTP by UDP please
The method asked also includes：
Receive the http response message that second network equipment sends, http response message includes http response text, HTTP
Response message is used for responding HTTP request message；
Specifically, UDP proxy server receives the http response message that second network equipment sends, this http response message
For responding the HTTP request message of UDP proxy server transmission.Then this http response message is processed, HTTP is rung
Answer message transformation to be UDP response message, then UDP response message is sent to first network equipment, complete whole HTTP request
Repeating process with response.
It is configured to parse a UDP head response of http response text, and sends a UDP to first network equipment and ring
Answer message, a UDP response message includes a UDP head response, http response text, so that first network equipment passes through parsing
First UDP head response, reads http response text, and a UDP head response includes the information for reading http response text.
Here, the UDP response message constructing in the present invention, is to distinguish and being not received by during response to be sent
The 2nd UDP response message difference, equally, in the present invention construction a UDP head response, be in order to distinguish and not have reception
Difference to the 2nd UDP head response being constructed during response.If second network equipment has response, it is configured to parse HTTP
First UDP head response of response text, responsive state code is inserted in this UDP head response.Then, send to first network equipment
First UDP response message, a UDP response message includes a UDP head response, http response text, so that first network sets
For by parsing a UDP head response, read http response text, a UDP head response is included for reading http response
The information of text.
Construction a UDP head response, for example, a UDP head response be by magic (1 byte), opcode (1 byte),
Compress (1 byte), total (1 byte), subidx (1 byte), status (1 byte), reserved1 (1 byte),
Reserved2 (1 byte), sequence (4 byte), bodylen (4 byte) are constituted, and wherein, magic is identification, the meaning of mark
Think, be term when defining agreement；Opcode is corresponding with request domain name, and proxy server selects business service according to opcode
The configuration domain name of device；Compress indicates content compression mode；Total represents that this complete response can be divided into how many UDP
Bag；It is currently that subidx represents for which response；Status inserts the HTTP conditional code of service server response；reserve1、
Reserve2 is reserved field.
In an optional embodiment of the present invention, if not receiving what second network equipment sent in Preset Time
Http response message, or receive the HTTP error response message that second network equipment sends, then construction the 2nd UDP response
Head, and send the 2nd UDP response message to first network equipment, the 2nd UDP response message includes the 2nd UDP head response, and second
UDP response message is used for notifying the failure of first network equipment UDP request message, so that first network equipment passes through parsing second
UDP head response, reads the information of UDP request message failure.
Specifically, comprise in the 2nd UDP head response of construction for notifying the failure of first network equipment UDP request message
Information, when the http response message not receiving the second network equipment transmission in Preset Time, or receives the second network
It is possible to directly send, to first network equipment, the response comprising UDP head response during the HTTP error response message that equipment sends
Message, so that first network equipment passes through to parse the 2nd UDP head response, reads the information of UDP request message failure.
In embodiments of the present invention, parse UDP request header from UDP request message, identify HTTP domain name, including：
Parse UDP request header from UDP request message, identify the requested service type of UDP request header；
The domain name being pre-configured with according to requested service type, identifies HTTP domain name.
Specifically, UDP proxy server parses UDP request header from UDP request message, due to this UDP request header be by
HTTP domain name construction to be visited it is possible to identify HTTP domain name, detailed process first passes through the industry identifying this request
Service type, the domain name being pre-configured with further according to requested service type, identifies HTTP domain name.
Pass through the less HTTP of UDP proxy requests, HTTP request here is for specific scene ability in the present invention
Use, the specific transactions of a such as specific company, compressed by this UDP proxy server and act on behalf of, an agency
Server only needs to act on behalf of several or regulation how many different domain names, so can use 1 byte here
Opcode represents a kind of type of service, first passes through the type of service that different domain names is compressed into 1 byte, then finds out this
Configuration domain name corresponding to type of service, the domain name further according to configuration and URI construct the HTTP request of standard.
Referring to Fig. 2, Fig. 2 is a kind of another kind of method acting on behalf of HTTP request by UDP provided in an embodiment of the present invention
Schematic flow sheet, comprises the steps：

Specifically, first network equipment constructs UDP request header according to its HTTP domain name to be visited, that is, in UDP request header
Comprising HTTP domain name, constructing UDP request header here primarily to being sent to UDP proxy server, due to UDP proxy server only
Identification UDP request message can be received, therefore act on behalf of by UDP to forward by HTTP request to be sent, realize quickly small-sized
The request of HTTP and response process.
Here, the UDP request header of construction, for example, UDP request header be by magic (1 byte), opcode (1 byte),
Compress (1 byte), reserved (1 byte), sequence (4 byte), bodylen (4 byte) are constituted；Wherein, magic
It is identification, the meaning of mark, be term when defining agreement；Opcode with request domain name corresponding, proxy server according to
Opcode is selecting the configuration domain name of service server；Compress indicates content compression mode；Reserved is reserved field；
Sequence is request identification, and client constructs and fills this field, and proxy server only needs in request
Sequence value inserts head response, is easy to the concrete response of client identification；Bodylen represents Uniform Resource Identifier in request
Length, response in represent response text length.
In addition, it is necessary to explanation, the first network equipment being previously mentioned in embodiments of the present invention and second network equipment,
Refer respectively to send the original sender of HTTP request and receive HTTP request recipient, for example, first network equipment is permissible
It is client, second network equipment can be server end, for meeting all-network appointed condition, belong to the present invention real
