Description
Technical Field
The invention relates to the technical field of computers, in particular to an information processing method and a terminal of an API gateway.
Background
The API gateway plays an important role in forwarding service traffic. In order to improve the performance of traffic forwarding, the gateway can cache the responded entity content in a disk of a server where the gateway is located based on the requested relevant information as a cached key, or store the returned entity content in a memory by using a cache plug-in. After the cache is opened, the requests are all preferentially acquired from the cache and are not forwarded to downstream services, so that the response speed is improved, and the pressure of a gateway and the downstream services is reduced.
The current technical solution can only use one strategy: the returned message is directly stored in the cache under the condition that the cache is allowed, and different cache storage modes cannot be judged and selected according to other strategies.
The problem that only one strategy can be adopted to select a cache storage medium is obvious, the current main scheme is to store the small files into a disk, if the disk cache stores too many small files, the read-write performance of the disk is influenced, and for frequent requests with the returned result of the small files, the effect of opening the disk cache is even inferior to that of the unopened state.
Another solution is to store the data directly into a memory cache, but because the memory is limited and the size of the memory is much smaller than the size of the disk. With the content of the cache increasing, the memory occupation will increase, thereby influencing the routing forwarding of the core capability of the API gateway as the gateway.

In this embodiment, the step S1 specifically includes:
receiving external information, acquiring a first cache storage strategy corresponding to an interface of the external information from a plurality of preset cache storage strategies according to an interface type of the external information or a preset interface regular matching rule, and if the external information is external request information and first characteristic data corresponding to the first cache storage strategy is the request URL, executing step S21;

In this embodiment, in order to enable the interface to provide better performance, a micro-service developer opens the gateway cache and configures a custom cache storage policy of the gateway cache. Taking the example of selecting different cache storage policies of the cache media according to the size of the returned data, when a developer configures the cache storage policies, the developer sets the feature data as the size of the returned data, sets a specific threshold value, and sets a cache media matching rule: the response data with the returned data size smaller than the threshold is stored in the memory cache medium, the response data with the returned data size larger than the threshold is stored in the disk cache medium, and the cache medium reading priority is additionally configured.
S3, performing corresponding reading or writing response information operation on the first cache medium according to the external information;
in this embodiment, when the external response information enters the cache storage policy, the size of the returned data is determined, if the size is larger than the preset threshold, the disk cache medium is selected for caching, and otherwise, the memory cache medium is selected for caching.
If the external information is external request information, the step S3 specifically includes:
judging whether the first cache medium has first response data corresponding to the external request information, if so, returning the first response data to the outside, otherwise, sending the external request information to a first server corresponding to a gateway to acquire the first response data, and storing the first response data into the first cache medium;
if the external information is external response information, the step S3 specifically includes:
writing the external response information to the first cache medium;
when the external information is external request information and the first characteristic data corresponding to the first cache storage policy is a returned data size, the process proceeds to step S4, where step S4 specifically includes:
s4, reading corresponding first response data from the corresponding cache media in sequence according to the preset cache media reading priority, if the first response data are successfully read, returning the first response data to the outside, and otherwise, sending the external request information to a first server corresponding to the gateway to obtain the first response data and storing the first response data into the first cache media.
In this embodiment, after receiving the request, the API gateway obtains the cache storage policy corresponding to the current request interface. In this example, the feature data corresponding to the cache storage policy is the size of the returned data, and therefore, the cache is sequentially queried from the cache medium according to the cache medium reading priority configured in advance by the user.
Referring to fig. 1 and fig. 3, a second embodiment of the present invention is:
based on the first embodiment, in this embodiment, a user wants to store all caches of certain specific URLs in a cache medium of redis. The user firstly configures a cache storage strategy, the strategy is named as a redis _ flexible cache storage strategy, and the rule in the strategy is that as long as a path of a request URL carries a flexible _ store, the cache data of the external request is stored in the redis.
In addition, the user needs to reconfigure the interface type or interface regular expression which is matched with the cache storage policy named redis _ flexible. After configuration is completed, as long as a request interface of an external request conforms to the corresponding type or interface regular expression, the request interface enters a redis _ flexible cache storage strategy.
In this embodiment, after entering the redis _ flexible cache storage policy, it is further determined whether the request conforms to a cache matching rule in the redis _ flexible cache storage policy: if the path of the request URL has a flexible _ store, if the path is judged to have the flexible _ store, the result of the request is cached to a specific redis caching medium. Similarly, when the cache is obtained, whether the cache exists is preferably inquired from the corresponding cache storage medium.
Referring to fig. 2, a third embodiment of the present invention is:
an information processing terminal 1 of an API gateway comprises a processor 2, a memory 3 and a computer program stored on the memory 3 and operable on the processor 2, wherein the processor 2 implements the steps of the first or second embodiment when executing the computer program.
In summary, according to the information processing method and terminal of the API gateway provided by the present invention, different cache storage policies are selected according to different interfaces, and according to the cache storage policies and the feature data of the response data, the returned response data is stored in a suitable API gateway cache medium according to the configuration of the cache storage policies, and the request also obtains response entity data from the corresponding cache medium through the gateway proxy according to the different cache storage policies and the feature data in the request, so as to improve the performance of the API gateway reverse proxy forwarding the routing request. Meanwhile, the problems caused by only using a single cache medium, such as the problems of overhigh memory occupation and frequent disk reading and writing of the memory cache or the disk cache, are solved.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes made by using the contents of the present specification and the drawings, or applied directly or indirectly to the related technical fields, are included in the scope of the present invention.
