Detailed Description
The embodiment of the application provides a session information generation method, a session information generation system and an application server.
In order to make the technical solutions in the embodiments of the present application better understood and make the above objects, features and advantages of the embodiments of the present application more comprehensible, the technical solutions in the embodiments of the present application are described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of a first embodiment of a session information generation method according to the present application is shown:
step 101: the session configuration file in the application server is upgraded from the first version to the second version.
The SESSION configuration file in the application server mainly includes configuration information such as attribute values of the SESSION KEY, for example, encryption attribute of the SESSION KEY, compression attribute of the SESSION KEY, encoding format of the SESSION KEY, and the like. After a SESSION operation is completed between the client and the application server, a corresponding SESSION KEY is generated according to configuration information in the SESSION configuration file, for example, if the configuration information indicates that the user name does not need to be encrypted, the user name generated in the SESSION KEY is unencrypted plaintext.
The configuration file in the application server may be upgraded as needed, and assuming that the configuration file before the upgrade is a first version, when the configuration information is changed, the configuration file may be upgraded from the first version to a second version, for example, the configuration information in the first version indicates that the user name does not need to be encrypted, and the configuration information in the second version indicates that the user name needs to be encrypted. The application server stores configuration files of different versions before and after upgrading, wherein configuration information of the configuration files before upgrading is used for reading the SESSION KEY, and configuration information in the configuration files after upgrading is used for generating the SESSION KEY.
Step 102: the application server receives a session request of the client, wherein the session request comprises session keywords stored according to the session configuration file of the first version and the version number of the first version.
When the current SESSION configuration file in the application server is upgraded from the first version to the second version, the SESSION KEY carried by COOKIE may still be the SESSION KEY generated according to the configuration information of the configuration file of the first version in the SESSION request sent by the client.
Step 103: and reading the session key words according to the configuration information in the session configuration file of the first version.
When the SESSION KEY carried in the SESSION request is the SESSION KEY generated according to the configuration information of the configuration file of the first version, the configuration file before and after the upgrade is stored in the application server, so that the corresponding configuration file can be found according to the version number of the first version carried in the SESSION request, and the SESSION KEY is read according to the configuration information of the configuration file. For example, the configuration information of the first version indicates that the user name does not need to be encrypted, and the application server may directly read the plaintext of the user name in the SESSION KEY.
Step 104: and when the session request is finished, generating a session key word according to the configuration information of the session configuration file of the second version, and finishing the current process.
When the SESSION request between the client and the application server is finished, a new SESSION KEY needs to be generated according to the configuration information of the SESSION configuration file of the second version, for example, the configuration information of the second version indicates that the user name needs to be encrypted, the application server encrypts the user name plaintext according to a set encryption rule to generate a user name ciphertext, and the user name ciphertext is the new SESSION KEY to be written into the client COOKIE this time.
Referring to fig. 2, a flowchart of a second embodiment of the session information generating method according to the present application shows in detail a process of generating session information after the session configuration information of the application server is upgraded:
step 201: the application server stores the first version of the session configuration file and the version number thereof.
The SESSION configuration file in the application server mainly includes configuration information such as attribute values of the SESSION KEY, for example, encryption attribute of the SESSION KEY, compression attribute of the SESSION KEY, encoding format of the SESSION KEY, and the like. After a SESSION operation is completed between the client and the application server, a corresponding SESSION KEY is generated according to the configuration information in the SESSION configuration file.
Step 202: the application server sends a subscription message to the configuration server requesting a session profile.
Configuration files in the application server may be upgraded as required, the upgrade may be performed manually by an administrator, configuration information after the upgrade is input in a management interface of the application server, or may be performed automatically by the configuration server.
In a large-scale application system, the number of application servers is large, so that the automatic upgrading mode through the configuration server is more efficient, the real-time performance is good, the application server adopting the automatic upgrading needs to send a subscription message requesting the SESSION configuration file to the configuration server in advance, and the application server sending the subscription message and the configuration server are located in the same local area network.
Step 203: and receiving a second version of the session configuration file pushed by the configuration server through broadcasting.
When the SESSION configuration file in the configuration server is upgraded from the first version to the second version, the configuration server broadcasts and pushes the upgraded second version of the configuration file in the local area network in real time, and the application server which sends the subscription message receives the SESSION configuration file.
Step 204: and saving the second version of the session configuration file and the version number thereof, and taking the second version of the session configuration file as the upgraded current session configuration file.
After receiving the upgraded SESSION configuration file of the second version, the application server stores the SESSION configuration file of the second version and the version number thereof, at this time, the application server simultaneously stores the SESSION configuration file of the first version and the SESSION configuration file of the second version, the SESSION configuration files are identified by the version numbers, and simultaneously, the application server sets the SESSION configuration file of the second version as the currently used SESSION configuration file.
Step 205: the application server receives a session request of the client, wherein the session request comprises session keywords stored according to the session configuration file of the first version and the version number of the first version.
When the current SESSION configuration file in the application server is upgraded from the first version to the second version, the SESSION KEY carried by COOKIE may still be the SESSION KEY generated according to the configuration information of the configuration file of the first version in the SESSION request sent by the client.
Step 206: and judging that the session key words in the session request are the session key words stored according to the configuration file of the first version according to the version number.
Step 207: and acquiring the stored configuration file of the first version according to the version number of the first version.
Step 208: and reading the session key words according to the configuration information in the session configuration file of the first version.
When the current SESSION configuration file in the application server is upgraded from the first version to the second version, the SESSION KEY carried by COOKIE may still be the SESSION KEY generated according to the configuration information of the configuration file of the first version in the SESSION request sent by the client.
Step 209: and after the session request is finished, generating a session key word according to the configuration information of the second version of the session configuration file.
When the SESSION request between the client and the application server is finished, a new SESSION KEY needs to be generated according to the configuration information of the SESSION configuration file of the second version, for example, the configuration information of the second version indicates that the user name needs to be encrypted, the application server encrypts the user name plaintext according to a set encryption rule to generate a user name ciphertext, and the user name ciphertext is the new SESSION KEY to be written into the client COOKIE this time.
Step 210: and writing the session key word generated according to the configuration information of the second version of the session configuration file and the version number of the second version into the client COOKIE, and ending the current process.
The following describes a session information generation process in the embodiment of the present application with reference to an application example:
assuming 1 month and 1 day, the version number of the SESSION configuration file initially stored in the application server is "version 1", and the attribute value of the user name in the configuration information of "version 1" is set to "no encryption required";
supposing that the user name of the client is Zhang III, after the client accesses the application server through the IE browser, the server writes a user name into the COOKIE of the client, and according to the indication of the version 1, the attribute value of the user name is set to be ' encryption-free ', so that the user name written into the COOKIE of the client is plaintext Zhang III ', and the SESSION KEY in the COOKIE is usually kept for one week and is not expired;
1 month and 2 days, the SESSION configuration file of the application server is assumed to be upgraded from 'version 1' to 'version 2', and the attribute value of the user name in the configuration information of 'version 2' is set to 'encryption required';
in 3 days after 1 month, the user name in the SESSION KEY stored in the client COOKIE is still "one third", that is, the SESSION KEY corresponding to "version 1" is not expired, when the client accesses the application server again, the client carries the identifier of "version 1", and the application server knows that the SESSION KEY carried by the SESSION access of the client is "version 1" according to the identifier, so that the configuration information in "version 1" is used, that is, the SESSION KEY of the client is read in an unencrypted manner;
after the session access is finished, the application server encrypts the username Zhang III according to the configuration information in the version 2, writes the encrypted username Zhang III into the client COOKIE, and notes that the version number is the version 2;
after the session communication, the application server side drives the client side to complete the compatibility and seamless upgrade of the session information.
It should be noted that, the above application example only takes writing the SESSION KEY into a single COOKIE, and when there are multiple clients accessing the server at the same time, the operation processes are consistent, and are not described herein again; in addition, if the version of the configuration file of the application server is upgraded for multiple times within a period of time, the client will obtain the SESSION KEY according to the upgraded latest version once after accessing the application server.
