Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance. The technical scheme of the application obtains, stores, uses, processes and the like the data, which all meet the relevant regulations of national laws and regulations.
Currently, internet banking systems deploy data centers in different regions, session requests initiated by users are distributed to a certain container of the data center through a Domain name resolution server (Domain NAME SERVER, DNS), load balancing LTM equipment, a firewall WAF (Web application protection system, also called as a website application level intrusion prevention system, web Application Firewall, WAF) and a Gateway, and a server responding to the session requests is operated in the container. But as the user initiates a session request multiple times, each session request may be distributed to different servers. For example, a first session request initiated by a user in the morning is assigned to data center A and a second session request initiated by a user in the afternoon is assigned to data center B. Since the data in the different data processing centers are not shared, data center B does not store the data involved in the first session in data center a, resulting in a failure of the second session request.
According to the session processing method provided by the embodiment of the invention, the association relation between the session identifier and the target server is established when the first session request is responded. When the second session request is responded, the target server is determined according to the association relation established in advance, so that a plurality of session requests initiated by the user can be responded by the same target server, the condition that the plurality of session requests initiated by the user are distributed to different servers for responding is avoided, and the fault tolerance rate is improved.
Example 1
Fig. 1 is a flowchart of a session processing method according to an embodiment of the present invention, where the embodiment is applicable to a case of responding to a web session request, and the method may be performed by a server that distributes a session request, and specifically includes the following steps:
Step 110, in response to the first session request, a target server of the distribution target data center responds to the first session request.
Wherein the first session request is a request initiated when the target domain name is first accessed.
The user accesses the homepage through the client. When the user first triggers the login page in the homepage, a first session request is triggered. The first session request is sent to a load balancing device, which distributes the first session request to a target server response of a target data center according to load conditions of the plurality of data centers. The target data center includes a plurality of containers, each container containing at least one server. Each container is secured by a firewall WAF, and the first session request is routed through the gateway to the target server through filtering by the firewall WAF.
After the user initiates the first session request, the user communicates with the target server through the channel established by the first session request to complete the business operation. The business operations may include business content contained in an online banking page, such as business operations of balance inquiry, money transfer, financial business transaction, and the like.
Alternatively, the target server that distributes the target data center responds to the first session request by:
Step 111, determining domain name information used by the client for subsequent access.
The client is a user operated device that initiates a first session request. Multiple pieces of domain name information can be set to provide access for different clients, so that slow response caused by centralized access of a user to one piece of domain name information is avoided. A fixed domain name information may be determined for subsequent access by the client. After the user triggers the first session request in the homepage, the user can jump according to the fixed domain name information, so that the jump stability is improved.
Optionally, determining domain name information used by the client for subsequent access may be implemented as:
And determining domain name information used by the client for subsequent access according to the region information of the first session request.
The regional information of the client can be acquired through the router frouter, and domain name information used by the client for subsequent access is determined according to the regional information. Illustratively, frouter is deployed under the home domain name. When the user accesses the homepage through the client and triggers the first session request in the homepage, frouter identifies the region information where the first session request is located, and determines domain name information according to the region information.
Step 112, allocating a target server for responding to the first session request, the target server being located at the target data center.
And the load balancing determines a target data center according to the load condition of each data center. A target server for responding to the first session request is determined by the target data center.
Step 113, domain name information is sent to the page, so that the client initiates a subsequent request of the first session request through the page.
And returning the domain name information determined in the step 111 to the page, wherein after the page acquires the domain name information, the follow-up requests of the first session request are all accessed by the domain name information.
Step 114, responding to the subsequent request by the target server.
Frouter can accurately acquire the region information of the client, further determine the fixed domain name information to the page, enable the client to access with the domain name information later, trigger the subsequent request, and improve the triggering stability of the session request.
Step 120, a session identifier of the first session request is obtained, and an association relationship between the session identifier and the target server is established.
The tomcat server can generate jsesionid, the jsesionid is used as a session identifier, and the association relationship between the jsesionid and the target server is established. The association represents a session request issued by the target server in response to the session represented by jsesionid. The same user has a unique session identification in one container, so the session can be marked inside the data center using jsesionid.
Optionally, the session identifier of the first session request is obtained, and the association relationship between the session identifier and the target server is established, which may be implemented by the following manner:
step 121, performing SSL offloading on the first session request, and determining a session identifier of the first session request according to the offloading result.
When the first session request is triggered, the first session request is transmitted over a secure socket protocol (Secure Sockets Layer, SSL). And performing secure socket protocol SSL offloading through the NAT64 network equipment to obtain an offloading result, wherein the offloading result comprises a session identifier first session request. A session identification is extracted from the first session request.
Step 122, marking according to the firewall device WAF in communication with the load balancing device LTM.
The load balancing device LTM may be connected to a plurality of data centers. Optionally, each data center may also set a load balancing device LTM at the data center level. Each server in the data center is configured with a firewall device WAF. By marking the load balancing device that transmitted the first session request and the firewall device WAF, the transmission path of the first session request can be recorded.
Step 123, obtaining a container at the back end of the firewall equipment WAF, wherein a target server for responding to the session request runs in the container.
The firewall equipment WAF is used for protecting the target server in the container, and the target server can be accurately positioned according to the marking of the firewall equipment WAF communicated by the load balancing equipment LTM.
And 124, establishing association relation according to the session identification, the firewall equipment and the container.
The firewall device and the container identify a path of the target server. The association relationship is used for associating the session identifier with the path of the target server.
And 130, responding to the second session request, determining a target server according to the association relation, and responding to the second session request through the target server.
The second session request is a session request re-issued by the user through the client. The second session request may be a session request triggered by the client in the first page for the nth time, and N may be an integer greater than or equal to 2. When the user initiates the second session request by the client, the page provides the page for the user to initiate the subsequent request of the second session request according to the domain name information. After receiving the second session request, the server determines a target server for responding to the user session request according to the association relationship obtained in step 120.
Optionally, determining the target server according to the association relationship may be implemented as:
Determining whether the association relation is valid according to the time interval of the second session request and the first session request; and if the association relation is effective, determining the target server according to the association relation.
Alternatively, a first preset interval of session hold may be configured. If the time interval between the second session request and the first session request is smaller than or equal to the first preset interval, the association relation is determined to be valid. Otherwise, if the time interval between the second session request and the first session request is greater than the first preset interval, determining that the association relationship is invalid.
Further, a second preset interval may also be set. The second preset interval may be a session maintenance interval between the load balancing LTM and the firewall device WAF. After receiving the first session request, the server establishes a transmission channel of session data between the load balancing LTM and the firewall device WAF, where the transmission channel remains valid for a second preset interval. If the second session request is received within the second preset interval, multiplexing of the transmission channels may be performed. And if the second preset interval is exceeded, releasing the transmission channel. And when the second session request is received beyond the second preset interval, reestablishing a transmission channel of the second session according to the association relation.
In the session processing method provided by the embodiment of the invention, in response to a first session request, a target server of a target data center is allocated to respond to the first session request, wherein the first session request is a request initiated when a target domain name is accessed for the first time; acquiring a session identifier of a first session request, and establishing an association relationship between the session identifier and a target server; and responding to the second session request, determining a target server according to the association relation, and responding to the second session request through the target server. Compared with the prior art that the session requests initiated by the users are distributed to different data centers, the embodiment of the invention can establish the association relation between the session identifier and the target server when the users initiate the first session request, and when the users initiate the second session request, the target server which responds to the user session request before is determined according to the association relation, and the second session request is responded by the target server, so that the session requests initiated by the same users for multiple times are responded by the same target server, and the fault tolerance of session processing is improved.
Example two
Fig. 2 is a flowchart of a session processing method according to a second embodiment of the present invention, as a further explanation of the foregoing embodiment, after determining domain name information used by a client for subsequent access, the method further includes: writing the domain name correspondence relation between the client and the domain name information into a configuration file; correspondingly, responding to the second session request by the target server includes: acquiring domain name information accessed by a client according to a configuration file; the domain name information is sent to the page so that the client initiates a subsequent request of the second session request through the page. The method can be implemented by the following modes:
Step 201, in response to the first session request, determining domain name information used by the client for subsequent access.
Step 202, writing the domain name correspondence between the client and the domain name information into a configuration file.
After determining the domain name information used by the client for subsequent access, the domain name information is written into the configuration file. The configuration file is used for storing domain name information used by the client.
Alternatively, the user may be assigned fixed domain name information based on the user name or client. For example, a certain group of users is assigned specific domain name information. When any user in the group users accesses the first page to trigger the session request, the specific domain name information is returned to the page of the group users for display. An administrator can quickly and accurately manage domain name information of a user through a configuration file. For example, when a web server of a certain domain name information fails and service distribution needs to be performed temporarily, the domain name information in the configuration file can be modified to quickly distribute, so that service access stability is improved.
Furthermore, specific domain name information can be configured for a part of users in the group users according to a preset proportion, and other users in the group users can determine the domain name information according to the region information. The method and the device realize the configuration of the domain name information for the user according to the preset proportion, and further compare the service operation effect of the specific domain name information and the domain name information determined according to the region information.
Step 203, allocating a target server for responding to the first session request, the target server being located in a target data center.
Step 204, domain name information is sent to the page, so that the client initiates a subsequent request of the first session request through the page.
Step 205, response to the subsequent request by the target server.
Step 206, obtaining the session identifier of the first session request, and establishing the association relationship between the session identifier and the target server.
Step 207, in response to the second session request, determining the target server according to the association relation.
Step 208, obtaining domain name information accessed by the client according to the configuration file.
Step 209, the domain name information is sent to the page, so that the client initiates a subsequent request of the second session request through the page.
Further, in step 202, after writing the domain name correspondence between the client and the domain name information into the configuration file, the method further includes:
Responding to the modification operation of the administrator, and modifying the domain name correspondence in the configuration file; obtaining abstract information of the configuration file according to the first time interval; determining whether the configuration file is updated according to the abstract information; if the configuration file is updated, acquiring updated domain name information according to the configuration file; and sending the updated domain name information to the page.
In order to ensure the real-time performance of the configuration file, the summary information can be acquired according to the first time interval. The summary information of the configuration file is calculated according to the MD5 Message-Digest Algorithm (MD 5). If the summary information obtained in adjacent time intervals is the same, it is determined that no update exists. Otherwise, if the abstract information obtained by the adjacent time intervals is different, determining that the update exists. At Frouter application start-up, the configuration file for the relevant domain name in the configuration center is loaded and the file is abstracted using the md5 algorithm. If there is an update, the updated configuration file is sent to frouter to improve accuracy of the domain name information. When frouter is started, the summary information of the configuration file is obtained at intervals of a first time (such as one minute), and if the values of the summary information obtained at adjacent time intervals are different, the file content is reloaded.
The session processing method provided by the embodiment of the invention can effectively shunt and timely and accurately update the domain name information through the configuration file, thereby improving the access stability of the client.
