Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1 and 2, the data acquisition method according to the preferred embodiment of the present invention includes the following steps:
and step S10, monitoring the preset interface, and acquiring data into the memory in real time.
Specifically, the preset interface includes an http interface, which is an API based on an http service and is an agreement for interaction between systems, and the so-called web service is actually an http interface, but is more standard and universal. The http interface mainly functions to better solve the interaction requirement between different systems (which may be different in function, development language, different in service provider, and the like, but are all based on http service), such as various interfaces of wechat public numbers, which can be called well whether developed by Java or PHP, whether developed by a company a or a company B, and whether to be used as a mall system or an enterprise promotion website.
The data acquisition mode of the invention supports the http (post and get) request mode, and acquires the data to the memory in real time by monitoring the http interface.
And step S20, acquiring the data stored in the memory, and sending the data to a Web platform.
Wherein the data comprises: structured log data and non-repetitive structured business data.
Specifically, the step S20 specifically includes: acquiring the structured log data (for example, as shown in fig. 2, the log data acquired from a television is the process event record data generated by a recording IT system) and the non-repetitive structured service data in the memory; and sending the structured log data and the non-repetitive structured service data in the memory to an interface of the Web platform (i.e. OpenResty).
OpenResty (also called ngx _ OpenResty) is a flexible Web platform based on NGINX, and provides many high-quality third-party modules, that is, OpenResty is a flexible Web platform implemented by expanding NGINX through Lua.
OpenResty is a powerful Web application server, Web developers can use the Lua scripting language to invoke various C and Lua modules supported by the Nginx, and more importantly, OpenResty can rapidly construct an ultrahigh-performance Web application system capable of concurrent connection response of more than 10K in performance.
And step S30, after the Web platform receives the data, writing the data into a distributed log system in real time through a built-in script.
Specifically, the step S30 specifically includes: the Web platform (OpenResty) successfully receives the structured log data and the non-repetitive structured service data through an interface; and the Web platform (OpenResty) writes the structured log data and the non-repetitive structured service data into a distributed log system (kafka) in real time through a built-in self-defined acquisition script.
Wherein, the Script (Script) is an executable file which is written according to a certain format by using a specific descriptive language; a scripting language, also known as a build-out language, or dynamic language, is a programming language used to control software applications, and scripts are usually stored in text (ascii) and are only interpreted or compiled when called. The content of the acquisition script is body data for analyzing the HTTP request.
Kafka is a distributed, partitioned, multi-replica, multi-subscriber, zookeeper-based coordinated distributed log system (which may also be considered an MQ system), commonly available for web/nginx logs, access logs, message services, and the like. The main application scenarios are: a log collection system and a messaging system.
That is to say, after OpenResty receives data, the data is directly written into kafka in real time through a built-in script, so that low latency, real-time performance and stability are guaranteed.
In the invention, data is submitted to an interface of OpenResty through an HTTP request, the OpenResty is internally provided with a self-defined acquisition script to directly write the data into kafka, and the script supports lua language and C language writing. The script content is body data for parsing the HTTP request and sending the body data to the configured kafka service.
Further, as shown in fig. 3, based on the above data acquisition method, the present invention also provides a data acquisition system, and the data acquisition system includes:
the data acquisition module 51 is used for monitoring a preset interface and acquiring data into a memory in real time;
the data transmission module 52 is configured to obtain data stored in the memory, and send the data to the Web platform;
and the data writing module 53 is configured to write the data into the distributed log system in real time through a built-in script after the Web platform receives the data.
The invention provides a high-performance data acquisition system based on OpenResty, unifies the data acquisition mode, does not need to deploy other components, and ensures low delay, real-time performance and stability. For example, the data part collects data of an order service end, the colleagues of the service end write codes to submit the order data to an OpenResty interface, and the data part collects and writes the order data into kafka in real time.
The key points of the invention are as follows: the scheme used previously is nginx + flux + kafka, and the current scheme is OpenResty + kafka, which has one less link in the process. The data acquisition scheme is unified, when the service acquisition is increased, only OpenResty needs to be directly deployed and comprises the uploaded self-defined acquisition script, no code needs to be written, the kafka can be acquired in real time, and the low delay, the real-time performance and the stability are guaranteed.
Further, as shown in fig. 4, based on the data acquisition method and system, the present invention also provides a terminal, which includes a processor 10, a memory 20, and a display 30.
