WebSocket 流
与 HTTP 不同,使用 WebSockets,当您需要特定信息时,您无需不断发出请求。WebSockets 会为您维护网络连接(如果操作正确)并监听更改。您可以在此处查看官方文档。
wscat -c wss://api.chainup.net/ws/ethereum/mainnet/<YOUR_API_KEY>
< {"jsonrpc": "2.0", "id": 0, "method": "eth_gasPrice"}
< {"jsonrpc": "2.0","id":0,"result":"0x6f56b59ac"}const Web3 = require('web3');
const web3 = new Web3("wss://api.chainup.net/ws/ethereum/mainnet/<YOUR_API_KEY>")
web3.eth.getBlockNumber().then(console.log) // -> 9022457
from web3 import Web3
websocket_url='wss://api.chainup.net/ws/ethereum/mainnet/<YOUR_API_KEY>'
w3 = Web3(Web3.HTTPProvider(websocket_url))
# You can check if the connection is established using isConnected function.
w3.isConnected()
# Output: TrueLast updated
