Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
In the invention, a corresponding configuration file is generated in advance according to the domain name, the release address and the application resource of each application program. And when a user access request is received, performing reverse proxy according to a pre-generated configuration file. The reverse proxy is that a proxy end is used for receiving a connection request on the Internet and then forwarding the request to a background server end on an internal network; and the result obtained from the background server is returned to the client requesting connection on the Internet.
Before describing the reverse proxy method and system of the present invention, a method of generating a configuration file of the present invention will be described. Fig. 1 is a schematic diagram of a main flow of a domain name management method in an embodiment of the present invention, and as shown in fig. 1, the domain name management method includes:
step S101, resolving a domain name creating request, and determining a domain name, a release address and application resources of an application program;
step S102, generating a configuration file of a test state; the configuration file includes: domain name, publishing address and application resource;
and step S103, releasing the configuration file of the test state.
The application resource refers to various resources required by the page running of the application program, for example, when a domain name of a certain secondary channel of the application program is created, the various resources required by the page running of the secondary channel are the application resources. When an access party of an application program sends a domain name creating request, an application and a domain name are created, and a binding release address and a corresponding application resource are created. The invention creates the configuration file of the test state based on the domain name of the user, and the configuration file can be released after the test is passed.
Optionally, after generating the configuration file of the test state, the method further includes: and responding to a domain name issuing request, generating a configuration file of an on-line state according to the configuration file of the test state, and issuing the configuration file of the on-line state. Illustratively, after the configuration file in the test state passes the test, the access side of the application program sends a domain name publishing request for instructing to publish the configuration file in the test state on line.
The configuration file of the test state or the online state is automatically generated according to the domain name, the release address and the application resource of the application program, the problems that the online process is complex, errors are easy to occur and decoupling of application and domain name management cannot be realized due to the fact that the configuration file is manually generated and then packaged and uploaded to the server when the application program is online every time can be solved, one-key release of the configuration file is realized, unified management of the domain name can be realized, and statistics and monitoring are easy to realize.
When the configuration file is released, the released configuration file can be saved in a database, so that the reverse proxy system can acquire the released configuration file from the database. Optionally, the step of publishing the configuration file comprises: the configuration file is saved to a database and synchronized to the cache of the reverse proxy system. The reverse proxy system mentioned herein refers to the reverse proxy system provided in the first aspect of the embodiments of the present invention. The request response speed can be increased by caching the configuration file, the consumption of database resources is reduced, and the system stability is improved.
Optionally, the configuration file further includes: and identifying the version. Illustratively, for the channel a, a configuration file of the test state of the channel a is created for the first time, the version identifier of the configuration file is marked as V1.0, the configuration file of the test state of the V1.0 version can be modified for many times after being released, the version identifier is not changed when the modification is performed each time, the configuration file of the online state is released after the test is passed, and the configuration file of the online state is formed, wherein the version identifier of the configuration file of the online state is still V1.0. When the configuration information of the channel a needs to be reconfigured, the configuration file of the test state of the channel a can be created again, the version identifier of the configuration file is marked as V2.0, the configuration file of the test state of the V2.0 version can be modified for many times after being released, the version identifier is unchanged when the modification is performed each time, the configuration file of the online state is released after the test is passed, the configuration file of the online state is formed, and the version identifier of the configuration file of the online state is still V2.0. And by analogy, the channel A configuration information is created according to the steps each time the channel A configuration information needs to be reconfigured.
The configuration file is managed through the version identification, so that the configuration file with the target version identification can be conveniently searched, the version rollback can be realized, and the maintenance cost is reduced.
Optionally, synchronizing the configuration file to a cache of the reverse proxy system includes: and generating a configuration updating message, and sending the configuration updating message to the reverse proxy system so that the reverse proxy system responds to the configuration updating message to acquire a configuration file from the database and store the configuration file in the cache.
In the actual application process, after receiving the configuration update message, the reverse proxy system may immediately perform the step of obtaining the configuration file from the database, or periodically perform the step of obtaining the configuration file from the database through a timing task. The configuration updating message is generated after the configuration file is generated, so that the configuration file in the cache can be updated in time, the configuration file can be automatically validated in real time under the condition of not restarting an application program, the configuration file can be automatically on line at regular time, and manual watching is not needed.
Optionally, before the step of publishing the configuration file, the method further includes: and checking the generated configuration file and confirming that the check is passed. The content of the check can be selectively set according to the actual situation, for example, whether the syntax and format of the configuration file are correct or not can be checked. By checking the configuration file, the situation that the configuration file is failed to be issued due to the fact that the configuration file does not meet the set requirement can be avoided.
The domain name management method can be realized based on an upstream (a data forwarding mode in Nginx) mode in an openness (a Web platform based on Nginx and Lua) environment, and is realized by relying on Nginx (an HTTP and a reverse proxy Web server) and Lua (a script language). The domain name management is carried out based on the openness environment, so that the cost can be reduced.
The domain name management method can solve the following problems caused by manually generating the configuration file and then packaging and uploading the configuration file to the server when the application program is online in the prior art: in the process of implementing the invention, the inventor finds that at least the following problems exist in the prior art, the configuration file is published by one key, the domain name can be uniformly managed, and the invention is easy to count and monitor: (1) the online process is complex and is easy to make mistakes; (2) the device cannot be automatically on-line at regular time and needs to be manually on duty; (3) no off-line operation is performed, and the later maintenance cost is high; (4) decoupling of applications from domain name management cannot be achieved.
According to a first aspect of embodiments of the present invention, a method of reverse proxy is provided.

step S202, acquiring a target configuration file corresponding to the target domain name; the target configuration file comprises a domain name, a release address and an application resource of the application program to be accessed;
and step S203, reverse proxy is carried out based on the target configuration file.
It should be noted that the target configuration file may be a configuration file of a test state generated and issued in response to the domain name creation request in advance, for example, after the target domain name is determined in response to the user access request in the test environment, a configuration file corresponding to the target domain name is screened from configuration files of various test states as the target configuration file. The target configuration file in the present invention may also be a configuration file of an online state that is generated and issued according to a configuration file of a test state in response to a domain name issuing request in advance, for example, after a target domain name is determined in response to a subsequent access request in a production environment, a configuration file corresponding to the target domain name is screened from configuration files of online states as a target configuration file.
Optionally, the configuration file is verified and verified before being released. The content of the check can be selectively set according to the actual situation, for example, whether the syntax and format of the configuration file are correct or not can be checked. By checking the configuration file, the situation that the configuration file is failed to be issued due to the fact that the configuration file does not meet the set requirement can be avoided.
The configuration file issued based on the domain name management method is subjected to reverse proxy, the problems that the online process is complex, errors are easy to occur and decoupling of application and domain name management cannot be realized due to the fact that the configuration file is manually generated and then packaged and uploaded to a server when an application program is online every time can be solved, one-key issuing of the configuration file is realized, unified management of the domain name can be realized, and statistics and monitoring are easy to realize.
Optionally, publishing means: and storing the configuration file to a database, or storing the configuration file to the database and synchronizing the configuration file to a cache. In the actual application process, the published configuration file can be directly obtained from the database. Optionally, the obtaining of the target configuration file corresponding to the target domain name includes: judging whether a target configuration file corresponding to the target domain name exists in a cache or not; if yes, obtaining the target configuration file from a cache; otherwise, the target configuration file is obtained from the database.
The cache may include a cache of the pre-launch and a cache of the production environment reverse proxy system. The reverse proxy system refers to a system for performing reverse proxy by using the reverse proxy method provided by the first aspect of the present invention based on a pre-published configuration file, and may include a pre-transmitter and a production environment reverse proxy system. The pre-issuing machine is a testing machine and is used for previewing the issuing effect of the configuration file in the testing state. And the production environment reverse agent system carries out reverse agent based on the configuration file which is released to be on-line, so that the configuration file in the on-line state formally takes effect.
Exemplarily, under a test environment, judging whether a target configuration file corresponding to the target domain name exists in a cache of a pre-transmitter; if yes, obtaining the target configuration file from a cache of a pre-transmitter; otherwise, the target configuration file is obtained from the database. Under the production environment, judging whether a target configuration file corresponding to the target domain name exists in a cache of a reverse proxy system of the production environment; if yes, obtaining the target configuration file from a cache of a reverse proxy system of the production environment; otherwise, the target configuration file is obtained from the database.
The request response speed can be increased by caching the configuration file, the consumption of database resources is reduced, and the system stability is improved.
Optionally, the target configuration file further includes: a version identification; judging whether a target configuration file corresponding to the target domain name exists in the cache or not, wherein the judging step comprises the following steps: determining a target version identification corresponding to the target domain name according to a preset reverse proxy rule; judging whether a configuration file with the target domain name and the target version identification exists in a cache; if yes, judging that the target configuration file exists in the cache; otherwise, judging that the target configuration file does not exist in the cache.
The pre-set reverse proxy rule is used to indicate an available profile corresponding to a user access request. For example, each time a new version of the profile is released, a user access request is automatically directed to the most recent version of the profile corresponding to the target domain name. When a user access request is received, a target domain name corresponding to an application program to be accessed is analyzed from the access request, then a configuration file with the latest version of the target domain name is obtained, reverse proxy is carried out based on the obtained configuration file with the latest version, so that the request can be directed to the configuration file with the latest version by modifying a preset reverse proxy rule when the version of the configuration file is changed, automatic offline of the configuration file with the old version is realized, and maintenance cost is reduced.
The configuration file of the online state is managed through the version identifier, and the target version identifier is determined according to the preset reverse proxy rule, so that the configuration file with the target version identifier is conveniently searched, the version rollback is realized, and the maintenance cost is reduced. On the other hand, when the version of the configuration file is changed, the preset reverse proxy rule is modified to enable the request to point to the configuration file of the latest version, so that automatic offline of the configuration file of the old version is realized, and the maintenance cost is reduced.
Optionally, the method for domain name management in the embodiment of the present invention is further characterized in that: responding to the configuration updating message, acquiring a configuration file from the database and storing the configuration file to a cache; or, the configuration file is obtained from the database through the timing task and is stored to the cache.
