SpringCloud GateWay custom filter GatewayFilter and AbstractGatewayFactory

1. GatewayFilter GatewayFilter is a simple interface used to define the behavior of a gateway filter. A gateway filter is a class that implements the GatewayFilter interface and can perform certain operations when a request enters the gateway or when a response leaves the gateway. Filters can be used to modify requests or responses, log, […]

HBase advanced features: filters (1)

Level 1: Use filters to query data in specified rows Knowledge points 1. Steps to use filters: (1) Create a filter: RowFilter(CompareOperator op,ByteArrayComparable rowComparator). The first parameter receives the comparison operation object, and the second parameter receives the condition. The first parameter has many values to match various scenarios. The value table is as follows: […]

[STM32] Several message reception filtering modes for STM32 CANFD peripherals

In Controller Area Network (CAN) systems, correctly configuring message filters is critical to effectively manage network communications. Especially when using the Flexible Data-rate Controller Area Network (FDCAN), choosing the appropriate filter type can greatly improve network efficiency and message processing speed. The CAN peripheral of the STM32G47x chip has the following reception message filtering methods: […]

How to use fiddler to capture mobile phone packets and filters!

1. The difference between Fiddler and other packet capture tools 1. Although Firebug can capture packets, it is not powerful enough to analyze the detailed information of http requests. The function of simulating HTTP requests is not enough, and Firebug often requires “no refresh modification”. If the page is refreshed, all modifications will not be […]

An ADC sampling algorithm, median average filtering + recursive average filtering

Foreword In actual AD acquisition scenarios, there will be effects of periodic changes and occasional pulse fluctuation interference on AD acquisition. Here a combination of median average filtering + recursive average filtering is used Refer to the code framework written by predecessors, and also refer to the blog below by blogger GuYH_, and make slight […]
