  >  https://admin:123456@bsn91000001.bsngate.com:19602/node1

  {
    "jsonrpc" : "2.0",
    "id" : 2,
    "result" : "0x365"
  }

3. Interact with node by Web3.js

Example:

  const Web3 = require("web3");

  const web3 = new Web3(
  new Web3.providers.HttpProvider("https://VuF0h0y7pLwtvDqjuW:y2sYuiIciR6JFtHbmC@bsnmu7d0gNn.bsngate.com:19602/node1")
