Infura is an API service provider for Ethereum and IPFS. 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.
