Description

Method and system for realizing API call information statistics based on InfluxDB
Technical Field
The invention discloses a method and a system for realizing API calling information statistics based on InfluxDB, and relates to the technical field of API calling.
Background
Kong is a highly available, easily extensible API Gateway project sourced by Mashape corporation based on the Nginx _ Lua module write. Since Kong is based on Nginx, it is possible to horizontally extend multiple Kong servers to handle large volumes of network requests by distributing the requests evenly to the individual servers through a pre-load balancing configuration.
Kong employs a plug-in mechanism for functional customization, with a set of plug-ins (which may be 0 or n) being executed during the life of the API request response cycle. Plug-ins are written using Lua, and there are currently several basic functions: HTTP basic authentication, key authentication, CORS (Cross-domain Resource Sharing), TCP, UDP, file logging, API request throttling, request forwarding, and nginx monitoring.
The cache database is one of the most popular NoSQL databases at present, is an open-source key-value pair storage database which is written by ANSI C, comprises a plurality of data structures, supports a network, is based on an internal memory and has optional persistence, and has the following characteristics:

After the lua-supporting script joins Kong, each client's request to the API will first arrive at Kong, which will then be proxied to the final API, and between the request and the response, Kong will execute any installed plug-ins, extending the API function set, and Kong effectively becomes the entry point for each API.
InfluxDB is an open source time-series data developed by InfluxData. The time sequence database is a database which is stored based on time, each piece of data has a time stamp, so the database is particularly suitable for storing the data which change along with the time, and the trend of the data which change along with the time can be analyzed after being processed by some tools.

s1, the issued API call information is stored in a cache database by utilizing the gateway kong;
s2, storing the calling information in the cache database into the InfluxDB at regular time;
s3, using the interface of InfluxDB to inquire the calling condition of API;
s4, directly storing the data of the processing specification into the InfluxDB in the plug-in;
realizing that the calling condition of Kong API is stored in a cache function through Lua codes, taking Redis as a cache database and taking InfluxDB as a database for storing the calling condition of API; when the API of the user is called, the called condition is saved in a cache, and then the data in the cache is saved to the InfluxDB by using a timing task;
when a user needs to create an API on a console page, a plug-in does not need to be bound, and kong can execute the plug-in for storing calling conditions when the API is called to store data into a cache database;
cache format
Storing application and API call information using hash format

Figure BDA0003510887830000061
Further, the specific steps of S2 for regularly saving the call information in the cache database to the InfluxDB are as follows:
s201, regularly caching data acquired as stored in a database by a timing task;
s202, the timing task stores the acquired data into the InfluxDB;
s203, the timing task judges whether the storage is successful or not, and the stored data is deleted successfully;
acquiring calling information of an API in batch from a redis cache by using a timing task, storing data into the InfluxDB in sdk batch by using the InfluxDB, and deleting the calling information from the redis cache after the data are successfully stored; the data is processed into the standard data stored in the InfluxDB in the plug-in unit, and the data is directly stored without independently processing the data by a timing task;
further, the specific steps of S3 querying the calling condition of the API using the interface of the infiluxdb are as follows:
s301, acquiring calling information of the API in batch from a cache of the cache database by using a timing task;
s302, sdk batches of data of the InfluxDB are used for storing the data into the InfluxDB, and after the data are successfully stored, the calling information is deleted from the cache database;
creating a timed task by using the note @ Scheduled in the SpringBoot, wherein the execution frequency of the timed task is 1 minute
@Scheduled(cron="0 0/1***?")
Further, the step S301 of obtaining the calling information of the API in batch from the cache of the cache database by using the timing task includes:
s3011, calling and saving information by the API, wherein APIg: monitor is used as the beginning of the key in the plug-in;
s3012, acquiring a certain number of key sets to obtain cursors of the scanning data of the cache database by means of scan commands of the cache database;
s3013, repeating the above operations until the cursor value is zero, and ending the current task;
API calls and stores information, uses APIg (android package) monitor as the beginning of a key in the plug-in, uses the scan command of redis to fetch a certain number of key sets each time, and simultaneously obtains the cursor of redis scanning data, wherein the cursor is the key value of the scanning data, thereby ensuring that repeated data cannot be obtained
By using the pipeline characteristic of the redis, the API call storage information can be obtained in batch according to the key set obtained from the redis only by one request;
the above operations are repeated continuously until the value of the cursor is 0, which indicates that there is no unsynchronized API call information data in redis, and the current task can be ended;
still further, in S302, sdk batches of data of the infiluxdb are stored in the infiluxdb, and the specific steps of deleting the call information from the cache database after successful storage are as follows:
s3021, judging whether other operation processes exist according to the value in the cache database;
s3022 writing identification data into the cache database;
s3023 identifying that the value of the data uses a timestamp;
s3024, deleting the identification data in the cache database after the current thread completes the synchronization data;
judging whether other processes are operated or not according to the values in the redis when the task starts, if other processes finish the current task immediately in the synchronous data and wait for the next task period to be executed again, and if no other processes are in the synchronous data, performing the following process;
writing a group of data into the redis when the task starts, wherein the data indicate that a thread is in synchronous data at present, and other threads do not need to operate;
the identification data is as follows
Key APIg:kong:monitor
Value time stamp
The value of the identification data uses the timestamp to prevent the problem that the exception occurs in the execution process of the current thread to cause data with different steps for a long time
Deleting identification data in redis by the current thread after the synchronous data is completed
The process lock is used for ensuring that only one process operates data, ensuring that the data processing is not disordered and ensuring the validity and the safety of the data;
each piece of API calling information data obtained from the redis is processed into a standard InfluxDB insertion statement in the plug-in unit without being processed again;
establishing connection of InfluxDB, and specifying a database name and a storage strategy, wherein the storage strategy is established together when a database is established, and the storage strategy must be specified when the connection is established, and storing API call information data acquired from redis by using a method for storing data in batches in an SDK;
after the storage is successful, the just created InfluxDB connection is closed, so that the waste of InfluxDB resources is avoided, and the influence on the InfluxDB query is avoided;
API call information data acquired from reis needs to be deleted from redis after being synchronized into InfluxDB, and the data are ensured to be synchronized only once
And deleting the keys at one time by using a transactional calling mode of redis, and rolling back the transaction if the deletion fails to ensure the integrity of the data.
