Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
It is shown in Figure 1 applied to Web service the embodiment of the invention discloses access method between a kind of multiple data centers,
This method includes：
Step S11：The Http requests that receiving terminal is sent.
Specifically, terminal proxy server receiving terminal is asked by the Http of TCP linkup transmits.
Step S12：The address information of server in being asked using Http, is searched in address scheme table set in advance
To the address information of server agent server corresponding with server.
Specifically, Http requests include the address information of destination server, and preserved in terminal proxy server pre-
Address information, the address of server agent server of server are have recorded in the address scheme table first set up, address scheme table
The corresponding relation of information and server and server agent server, therefore, the address letter of the server in being asked using Http
Breath, can find the address information of server agent server corresponding with server in address scheme table.
Step S13：Using the address information of server agent server, Http requests are sent to server agent service
Device.
Specifically, terminal proxy server is found after the address information of server agent server, Http is asked to send out
Server agent server is delivered to, wherein, terminal proxy server can choose the free time from the TLS connection pools pre-established
Connection, obtains a TLS being connected with server agent server and is connected, and Http requests are extremely serviced using TLS linkup transmits
Device proxy server, transmits data using TLS encryption connections, improves security of the data in transmittance process.
Step S14：The Http that the reception server proxy server is sent is replied.
It it should be noted that being managed by TLS connection poolizations, can be connected with the multiplexing of maximum possible, improve connection and use
Efficiency, therefore, terminal proxy server can be replied with the reception server proxy server using the Http of TLS linkup transmits, its
In, the TLS connections between terminal proxy server and server agent server do not change, still for terminal proxy server to
Server agent server sends the TLS connections of Http requests, realizes TLS connection multiplexings.
Step S15：Http is replied and sent to terminal.
In the embodiment of the present invention, terminal proxy server can utilize the first mapping relations, and Http is replied and passes through terminal
TCP linkup transmits to terminal；Wherein, the first mapping relations are the corresponding relation that TLS connections are connected with the TCP of terminal, first
Mapping relations utilize terminal and terminal when terminal proxy server is set up the TLS connected with server agent server and is connected
The mark of TCP connections is connected and bound with TLS between proxy server, so as to obtain the first mapping relations, is closed using the first mapping
System can determine that TLS connections are corresponding with that terminal, terminal proxy server is quickly sent Http to terminal and answer
It is multiple, without recycling the address information in Http answers to search the address information of terminal.
It can be seen that, communication of the embodiment of the present invention between terminal and server, as transfer, makes end using proxy server
The Http requests that end is sent are sent to terminal proxy server, then are sent Http requests to server by terminal proxy server
Proxy server, and the Http answers that the reception server proxy server is sent, and last reply Http is forwarded to terminal, it is real
Access method between efficient and simple multiple data centers is showed.
The embodiment of the invention also discloses access method between a kind of multiple data centers, applied to Web service, referring to Fig. 2 institutes
Show, this method includes：
Step S21：The Http requests that receiving terminal proxy server is sent.
Specifically, what server agent server can be sent by TLS connection receiving terminals terminal proxy server
Http is asked.
Step S22：Server address information in being asked using Http, Http requests are sent to server.
Specifically, server agent server can utilize TCP connections, Http requests are sent to server.
Further, the corresponding relation that TLS connections are connected with TCP can be now set up, TLS connections is connected with TCP
Mark is bound, so as to obtain the second mapping relations.
Step S23：The Http that the reception server is sent is replied.
Specifically, after the complete Http requests of server process, server generation Http is replied, and server agent server connects
The Http for receiving server generation is replied.
Step S24：Http is replied and sent to terminal proxy server.
Specifically, server agent server, it is possible to use the second mapping relations judge the TCP connections that server is used
Corresponding TSL connections, are acted on behalf of so that Http be replied by TLS linkup transmits to terminal server corresponding with server；Its
In, the second mapping relations are that terminal proxy server sends pair that Http asks the TLS connections used to be connected with the TCP of server
It should be related to.
