I. Infura API obtains the current configuration chain ID of Ethereum - Blockchain data development practice

Introduction: Infura is an API service for Ethereum and IPFS provider. Infura initially only provided stable and reliable RPC access for ConsenSys internal projects. Later, with the development of the Ethereum ecosystem, they realized that they could play a greater role, so they began to provide public API services to developers. This article summarizes the implementation of using the Infura API to obtain the current configuration chain ID of Ethereum.

This article summarizes the implementation of using the Infura API to obtain the current configuration chain ID of Ethereum.

Infura API official documentation: https://infura.io/docs

To use the API, you need to apply for a Project ID. The ID is free to apply for. The application process is "Register-Login -Create a new project", no review is required and it can be done in a few minutes.

Infura API standard request port format:

In this example we use the HTTP-based Ethereum mainnet JSON-RPC port:
